Abstract
A snowmobile throttle control apparatus includes a pair of bushings with a hole and closed ends and a separate axle pin. The bushings are assembled to a thumb lever and mounted over the axle pin. The axle pin allows for a controlled gap to be maintained between the throttle lever, bushing assembly and the control housing. The thumb lever is allowed to flex open when a side load is applied. Thus allowing the thumb lever assembly to travel without binding on the control housing. This insures proper functioning of the RPS feature.

DETAILED DESCRIPTION

The particular values and configurations discussed in these non-limiting examples can be varied and are cited merely to illustrate at least one embodiment and are not intended to limit the scope thereof.


Referring to FIG. 1, a perspective view of a snowmobile 100 is illustrated, which can be implemented in accordance with a preferred embodiment. The snowmobile 100 generally includes a frame 120 having a pair of skis 125 coupled to the forward portion. The RPM of the engine of snowmobile 100 can be selectively adjusted utilizing a throttle lever 110 mounted on a right handle bar 115 of snowmobile 100. A hand grip 105 is generally attached to a right handle bar 115 of snowmobile 100.


Referring to FIG. 2 an exploded view of a throttle control mechanism 200 of a snowmobile, such as snowmobile 100 depicted in FIG. 1, can be implemented in accordance with a preferred embodiment. Note that in FIGS. 1-2, identical or similar parts or elements are generally indicated by identical reference numerals. For example, the throttle lever 110 depicted in FIG. 1 also appears in FIG. 2. As depicted in FIG. 2, a Runaway Prevention Switch (RPS) 275 can be provided, which includes a pair of screws 245, a cover 220, a connector assembly 255 containing a micro-switch, an external spring 260, an internal spring 265, a small plunger 225 and a large plunger 230. The RPS 275, throttle lever 110, an axle pin 210 and a pair of bushing 205 are housed into a control housing or case 215. The bushings 205 can be assembled to a pair of legs 240 in the throttle lever 110 and mounted over the axle pin 210. The axle pin 210 maintains a controlled gap between the throttle lever 110 and control housing 215.


Referring now to FIG. 3, a perspective view of a throttle control mechanism 300 for a snowmobile 100 is illustrated, which can be implemented in accordance with a preferred embodiment. The configuration depicted in FIG. 3 is essentially an imploded view of the configuration illustrated in FIG. 2. Note that in FIGS. 1-4, identical or similar parts or elements are indicated by identical reference numerals. Thus, the FIG. 3 illustration also depicts the control housing 215, throttle lever 110, a pair of legs 240, an axle pin 210 and a bushing 205, which are described above with respect to FIG. 2.


Referring to FIG. 4, a sectional view of a throttle control mechanism 400 of snowmobile 100 is illustrated taken along section line A-A of FIG. 3, in accordance with a preferred embodiment. The configuration depicted in FIG. 4 illustrates the control housing 215, throttle lever 110, a pair of legs 240, an axle pin 210 a RPS 275 and a bushing 205 as depicted previously with respect to in FIG. 2.


Referring to FIG. 5A-5B, FIG. 5A illustrates a perspective view of a throttle control mechanism 502 of snowmobile 100, and FIG. 5B depicts a sectional view of a throttle control mechanism 504 of snowmobile 100 taken along line A-A of FIG. 5A, in accordance with a preferred embodiment. With reference to the perspective view of the throttle control mechanism 502, the cross sectional view of throttle control mechanism 504 is shown along the lines A-A. Note that in FIGS. 1-5A/5B identical or similar parts or elements are generally indicated by identical reference numerals. Thus, the FIG. 5B illustration also depicts the control housing 215, throttle lever 110, an axle pin 210 and a bushing 205 which are described above with respect to FIG. 2.


It will be appreciated that variations of the above-disclosed and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. Also that various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
