A connecting rod (11) can be pivotally connected by a first end (12) to the central bell crank (2) and pivotally connected by a second end (13) to a rotary actuator (14). The rotary actuator (14) can include an actuator horn (14′) connected to the second end (13) of the connecting rod (11).


In various embodiments, the central bell crank (2), the first bell crank (6), or the second bell crank (10) can be disposed in various structural forms capable of changing motion through an angle. The illustrative examples of the bell cranks (2) (6) or (10) shown in the Figures are not intended to preclude embodiments which incorporate similar or equivalent crank arms, crank levers, angled levers, suspension arms, or rocker arms, currently or prospectively available, and the fixed pivot or the moving pivots of the bell cranks (2) (6) or (10) can, but need not necessarily, further incorporate a bushing assembly or a bearing assembly to align, guide, or support the bell crank (2) (6) or (10) or reduce wear or friction. Further, while the illustrative examples may show pivot axes defined by pivot pins; this is not intended to preclude the use of pivot balls, pivot joints, ball joints, living hinges, or other structures which allow the fixed pivot or moving pivots of the bell cranks (2) (6) (10) to operate in relation to one another. Further, in various embodiments, the rotary actuator (14) can, but need not necessarily, be a commercially available servo motor used with toy and radio control vehicles. As an illustrative example, a servo motor suitable for use in embodiments can be a Redcat Racing Hexfly HX 15s 200 oz waterproof high torque metal gear servo available from Redcat Racing, 3145 East Washington Street, Phoenix, Arizona 85034. However, this illustrative example of a rotary actuator (14) is not intended to preclude embodiments which incorporate similar or equivalent devices that produce rotary motion or torque, such as high speed and high torque servo motors, currently or prospectively available.


Again, referring primarily to FIGS. 1 through 5, in particular embodiments, the vehicle suspension (1) can further include a first adjustable-length member (15) having a first end mount (16) opposite a second end mount (17). The first adjustable-length member (15) connects to the first bell crank (6) at the first end mount (16). In particular embodiments, the first adjustable-length member (15) can, but need not necessarily, be a commercially available shock absorber or strut used in toy and radio control vehicles. As one illustrative example, an adjustable-length member (15) suitable for use in embodiments, can be a Redcat Racing Shock Absorber Part No. 86002 available from Redcat Racing, 3145 East Washington Street, Phoenix, Arizona 85034. However, the illustrative examples of the first adjustable-length member (15) described in the specification or shown in the Figures are not intended to preclude embodiments which incorporate similar or equivalent toy vehicle shock absorbers, currently or prospectively available. In yet further embodiments, the first adjustable-length members (15) can, but need not necessarily, be a rigid linkage connected to torsion bars, or the like, in or for use with adjustable height suspensions.


Now, referring primarily to FIGS. 1 through 3, embodiments of the vehicle suspension (1) can include a first vertical suspension assembly (18) pivotally coupled to the vehicle chassis (VC). The first vertical suspension assembly (18) interconnects a first wheel (W1) to the first adjustable-length member (15) allowing generally vertical movement of the first wheel (W1) in relation to the vehicle chassis (VC). In particular embodiments, the first vertical suspension assembly (18) can include a lower suspension linkage (19) extending from a pivotal coupling on the vehicle chassis (VC) to connect with the second mount (17) of the first adjustable-length member (15), and a first upper wishbone linkage (20) having a first arm (21) and a second arm (22) extending in general parallel relationship to one another (21, 22) from corresponding pivotal couplings on the vehicle chassis (VC) to a first knuckle (23). The first wishbone linkage (20) disposed above the first lower suspension linkage (19), aligns the first mount (16) of the first adjustable-length member (15) connected to the first bell crank (6) with the second mount (17) of the first adjustable-length member (15) connected to the first lower suspension linkage (19) allowing the first adjustable-length member (15) to pass between the first arm (21) and the second arm (22) of the first upper wishbone linkage (20). A first two-ended member (24) can interconnect the first upper wishbone linkage (20) to the first lower suspension linkage (19). A first axle (25) can be rotatably mounted in the first two-ended member (24). The first wheel (W1) can be rotatably coupled to the first axle (25).


Again, referring primarily to FIGS. 1 through 3, the vehicle suspension (1) can further include a second adjustable-length member (26). The second adjustable-length member (26) can have a first mount (27) connected to the second bell crank (10). In substantially similar structural arrangement to the first vertical suspension assembly (18), embodiments can further include, a second vertical suspension assembly (29). The second vertical suspension assembly (29) interconnects a second wheel (W2) to the second adjustable-length member (26). The second vertical suspension assembly (29) can include a second lower suspension linkage (30) connected to a second mount (28) of the second adjustable-length member (26). A second upper wishbone linkage (31) includes a first arm (32) and a second arm (33) which correspondingly extend from pivotal couplings on the vehicle chassis (WC) in a substantially parallel relationship to a second common knuckle (34). The second upper wishbone linkage (31) can be disposed above the second lower suspension linkage (30), to align the first mount (27) of the second adjustable-length member (26) connected to the second bell crank (10) with the second mount (28) of the second adjustable-length member (26) connected to the second lower suspension linkage (30) allowing the second adjustable-length member (26) to pass between the first arm (32) and the second arm (33) of the second upper wishbone linkage (31). The vertical suspension assembly (29) can include a second two-ended member (35) which interconnects the second upper wishbone linkage (31) to the second lower suspension linkage (30). A second axle (36) can be rotatably mounted in the second two-ended member (35). The second wheel (W2) can be rotatably coupled to the second axle (36).


Again, referring primarily to FIGS. 1 through 5, in particular embodiments, the central bell crank (2) can be pivotally mounted on the vehicle chassis (VC) to axially pivot along the longitudinal axis (LA) of the vehicle chassis (VC) interconnecting the connecting rod (11) to the first link (3) and second link (7). The first link (3) and second link (7) can be disposed side-by-side to one another in vertical orientation to connect second ends (5) (9) to the central bell crank (2). Each of the first ends (4), (8) of the first link (3) and the second link (7) can correspondingly couple to the first bell crank (6) and second bell crank (10) each mounted to the vehicle chassis (VC) to transversely pivot across the longitudinal axis (LA) of the vehicle chassis (VC). Operation of the rotary actuator (14) moves the connecting rod (11) to generate operative interconnection between the central bell crank (2), the first bell crank (6) and the second bell cranks (10) to concurrently transfer sufficient force through the first adjustable-length member (15) and the second adjustable-length member (26) to downwardly lower the first vertical suspension assembly (18) and the second vertical suspension assembly (29) in relation to the vehicle chassis (VC) to correspondingly upwardly raise the vehicle chassis (VC) in relation to the support surface (SS). In particular embodiments, the downward movement of the first vertical suspension assembly (18) and the second vertical suspension assembly (29) can occur with sufficient force to cause the first wheel (W1) and the second wheel (W2) to hop off the support surface (SS), whether the vehicle is either stationary or in motion. In particular embodiments, the rotary actuator (14) can be repeatedly actuated to cause a repeated hopping motion of the vehicle chassis (VC) in relation to the support surface (SS).


Now referring primarily to FIGS. 1, 2 and 3, the rotary actuator (14) can, but need not necessarily, have a square center section with opposite extending brackets for mounting to the vehicle chassis (VC). The rotary actuator (14) in operation via radio control, can be connected to an offset actuator horn (14′), which can be connected to a second end (13) of the connecting rod (11). When the rotary actuator (14) actuates the connecting rod (11), the radial movement of the actuator horn (14′) can converted into movement in the form of a rearward pull of the connecting rod (11).


Now, referring primarily to FIGS. 3 and 4, a steering linkage (S) (shown in broken line) can, but need not necessarily, be operated by an additional rotary actuator (14c) via radio control.


Now, with general reference to FIGS. 6 through 10, in particular embodiments, the central bell crank (2) can comprise a first central bell crank (2′) and a second central bell crank (2″). The first central bell crank (2′) and the second central bell crank (2″) can each be pivotally mounted on the vehicle chassis (VC) to axially pivot along the longitudinal axis (LA) of the vehicle chassis (VC). The first bell crank (6) and the second bell crank (10) can be pivotally mounted on the vehicle chassis (VC) to transversely pivot along the transverse axis (TA) of the vehicle chassis (VC). A first link (3) can have a first end (4) connected to the first bell crank (6) and a second end (5) can be connected to the first central bell crank (2′). A second link (7) can have a first end (8) connected to the second bell crank (10) and a second end (9) can be connected to the second central bell crank (2″). A first end mount (16) of a first member (15) can be connected to the first bell crank (6) and a second end mount (17) of the first member (15) can be connected to a first vertical suspension assembly (18) pivotally coupled to the vehicle chassis (VC). A first wheel (W1) can be interconnected to the first vertical suspension assembly (18). A first end mount (27) of a second member (26) can be connected to the second bell crank (10) and a second end mount (28) of the second member (26) can be connected to a second vertical suspension assembly (29) pivotally coupled to the vehicle chassis (VC). A second wheel (W2) can be interconnected to the second vertical suspension assembly (29). The first member (15) and the second member (26) can have a fixed non-adjustable length. In particular embodiments, the first member (15) and the second member (26) can correspondingly comprise a first adjustable-length member and a second adjustable-length member. The first adjustable-length member and a second adjustable-length member can be configured as mechanical shock absorber.


Operative interconnection of the first central bell crank (2′), the first bell crank (6), the first member (15), and the first vertical suspension assembly (18) can move the first wheel (W1) independent of movement of the second wheel (W2) to corresponding lift and lower one side of the vehicle chassis (VC) independent of the other side of the vehicle chassis (VC). That is, lift and lower one of the left side or the right side of a vehicle chassis (VC). Operative interconnection of the second central bell crank (2″), the second bell crank (10), the second member (26) and the second vertical suspension assembly (29) can move the second wheel (W2) to lift and lower one side of the vehicle chassis (VC) independent of the other side of the vehicle chassis (VC). That is, lift and lower the other one of the left side or the right side of a vehicle chassis (VC).


A first connecting rod (11′) can be pivotally connected by a first end (12′) to the first central bell crank (2′) and pivotally connected by a second end (13′) to a first rotary actuator (14a). The first rotary actuator (14a) can include an actuator horn (14a′) connected to the second end (13′) of the first connecting rod (11′). Operation of the first rotary actuator (14a) moves the first connecting rod (11′) to generate operative interconnection between the first central bell crank (2′) and the first bell crank (6) to concurrently transfer sufficient force through the first member (15) to downwardly lower the first vertical suspension assembly (18) in relation to the vehicle chassis (VC) to correspondingly upwardly raise one side of the vehicle chassis (VC) in relation to the support surface (SS). In particular embodiments, the downward movement of the first vertical suspension assembly (18) can occur with sufficient force to cause the first wheel (W1) to hop off the support surface (SS), whether the vehicle is either stationary or in motion. In particular embodiments, the first rotary actuator (14a) can be repeatedly actuated to cause a repeated hopping motion of one side of the vehicle chassis (VC) in relation to the support surface (SS).


A second connecting rod (11″) can be pivotally connected by a first end (12″) to the second central bell crank (2″) and pivotally connected by a second end (13″) to a second rotary actuator (14b). The second rotary actuator (14b) can include an actuator horn (14b′) connected to the second end (13″) of the second connecting rod (11″). Operation of the second rotary actuator (14b) moves the second connecting rod (11″) to generate operative interconnection between the second central bell crank (2″), the second bell crank (10) to concurrently transfer sufficient force through the second member (26) to downwardly lower the second vertical suspension assembly (29) in relation to the vehicle chassis (VC) to correspondingly upwardly raise the other side of the vehicle chassis (VC) in relation to the support surface (SS). In particular embodiments, the downward movement of the second vertical suspension assembly (18) can occur with sufficient force to cause the second wheel (W2) to hop off the support surface (SS), whether the vehicle is either stationary or in motion. In particular embodiments, the second rotary actuator (14b) can be repeatedly actuated to cause a repeated hopping motion of the other side of the vehicle chassis (VC) in relation to the support surface (SS).


Each of the first rotary actuator (14a) and the second rotary actuator (14b) can operated independent of the other rotary actuator, to allow each side of the vehicle chassis (VC) to be independently raised and lowered independent of the other side of the vehicle chassis (VC). Each of the first rotary actuator (14a) and the second rotary actuator (14b) can operated concurrently to concurrently raise and lower both sides of the vehicle chassis (VC). In particular embodiments, the first rotary actuator (14a) and the second rotary actuator (14b) can be repeatedly actuated to cause a repeated hopping motion of both wheels (W1, W2) in relation to the support surface (SS).


As can be easily understood from the foregoing, the basic concepts of the present invention may be embodied in a variety of ways. The invention involves numerous and varied embodiments of a vehicle suspension apparatus, a method of making a vehicle suspension, a method of using a vehicle suspension apparatus to make a remote control car hop, and the component parts thereof, including the best mode.


As such, the particular embodiments or elements of the invention disclosed by the description or shown in the figures or tables accompanying this application are not intended to be limiting, but rather exemplary of the numerous and varied embodiments generically encompassed by the invention or equivalents encompassed with respect to any particular element thereof. In addition, the specific description of a single embodiment or element of the invention may not explicitly describe all embodiments or elements possible; many alternatives are implicitly disclosed by the description and figures.


It should be understood that each element of an apparatus or each step of a method may be described by an apparatus term or method term. Such terms can be substituted where desired to make explicit the implicitly broad coverage to which this invention is entitled. As but one example, it should be understood that all steps of a method may be disclosed as an action, a means for taking that action, or as an element which causes that action. Similarly, each element of an apparatus may be disclosed as the physical element or the action which that physical element facilitates. As but one example, the disclosure of a “crank” should be understood to encompass disclosure of the act of “cranking”—whether explicitly discussed or not—and, conversely, were there effectively disclosure of the act of “cranking”, such a disclosure should be understood to encompass disclosure of a “crank” and even a “means for cranking.” Such alternative terms for each element or step are to be understood to be explicitly included in the description.


In addition, as to each term used it should be understood that unless its utilization in this application is inconsistent with such interpretation, common dictionary definitions should be understood to be included in the description for each term as contained in the Random House Webster's Unabridged Dictionary, second edition, each definition hereby incorporated by reference.


All numeric values herein are assumed to be modified by the term “about”, whether or not explicitly indicated. For the purposes of the present invention, ranges may be expressed as from “about” one particular value to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value to the other particular value. The recitation of numerical ranges by endpoints includes all the numeric values subsumed within that range. A numerical range of one to five includes for example the numeric values 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, and so forth. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. When a value is expressed as an approximation by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. The term “about” generally refers to a range of numeric values that one of skill in the art would consider equivalent to the recited numeric value or having the same function or result. Similarly, the antecedent “substantially” means largely, but not wholly, the same form, manner or degree and the particular element will have a range of configurations as a person of ordinary skill in the art would consider as having the same function or result. When a particular element is expressed as an approximation by use of the antecedent “substantially,” it will be understood that the particular element forms another embodiment.


Moreover, for the purposes of the present invention, the term “a” or “an” entity refers to one or more of that entity unless otherwise limited. As such, the terms “a” or “an”, “one or more” and “at least one” can be used interchangeably herein.


Thus, the applicant(s) should be understood to claim at least: i) the vehicle suspension apparatus disclosed and described, ii) the related methods and systems disclosed and described, iii) similar, equivalent, and even implicit variations of each of the structure and method, iv) those alternative embodiments which accomplish each of the functions shown, disclosed, or described, v) those alternative designs and methods which accomplish each of the functions shown as are implicit to accomplish that which is disclosed and described, vi) each feature, component, and step shown as separate and independent inventions, vii) the applications enhanced by the various systems or components disclosed, viii) the resulting products produced by such systems or components, ix) methods and apparatuses substantially as described hereinbefore and with reference to any of the accompanying examples, x) the various combinations and permutations of each of the previous elements disclosed.
