This invention relates to articulated vehicles and more particularly to an apparatus permitting pitch, yaw and roll interrelationship between multiple vehicle units.
Articulated vehicles with apparatus permitting yaw, pitch and roll interconnections are known in the arts including U.S. Pat. No. 4,545,454 to Bas; U.S. Pat. No. 5,366,299 to Hughes; U.S. Pat. No. 4,482,165 to Dawson et al; and U.S. Pat. No. 5,456,185 to Rother et al. The patents referred to herein are provided herewith in an Information Disclosure Statement in accordance with 37 CFR 1.97.
The present invention is an apparatus creating yaw, pitch and roll interconnections between vehicles in a multiple unit vehicle. Pitch is provided by a hinge connection with one hinge first leaf affixed, generally by an immovable affixing means including welding, bolting, riveting and other such immovable means to a first vehicle unit. The first leaf is connected to a second leaf by hinge means provided in the preferred embodiment as a shaft received by outwardly extending planar elements, presenting apertures, extending from each of the first leaf and the second leaf thereby permitting shaft interconnection of the first leaf and the second leaf allowing the first leaf and the second leaf to revolve relative to the other. The orientation of the first and second hinged leaves, comprising the pitch assembly, is such as to respond with pitch movement, between the first and the second vehicle when the vehicle is subject to a pitch position as it transits terrain.
A roll assembly comprised or roll means and provided, in the preferred embodiment, of a threaded unit received by a complementary threaded unit. Those of ordinary skill in the mechanical arts will recognize that other threaded configurations will provide an equivalent function. The complementary threaded unit, either male or female, depending on the form of the threaded unit, is affixed by means to a second vehicle. Such affixing means includes but is not limited to welding, bolting, riveting and other such immovable affixing means. The threaded unit is affixed to a threaded unit plate again by such similar affixing means. The roll assembly is interconnected to the second vehicle unit in an orientation to allow roll movement between the first vehicle unit and the second vehicle unit when the multi-unit vehicle traverses terrain imposing roll forces of the first vehicle unit relative to the second vehicle unit. The threaded unit plate of the roll assembly and the second leaf of the pitch assembly are interconnected by the yaw assembly.
The yaw assembly is comprised of at least one plate extending from the second leaf to present an aperture for alignment with at least one plate extending from the threaded unit plate which presents an aperture for alignment with said apertures receiving shaft joining means. The orientation of the yaw assembly plates is such as to allow yaw movement between the first vehicle unit and the second vehicle unit when the first vehicle unit yaw turns relative to the second vehicle unit. The aligned apertures receive either rotatable shaft means and or yaw motor means. A yaw motor, comprised in the preferred embodiment of an electric, pneumatic or hydraulic motor, is immovably affixed to either the plate extending from the second leaf or the plate extending from the threaded unit plate with a shaft and key-notch interconnecting with the opposing plate so as to exert yaw forces on the respective second leaf and threaded unit plate thereby creating a turning force vis-a-vis the first and the second units. A vehicle steering means will provide electric, pneumatic and or hydraulic signals or forces at the yaw motor means causing the exertion of yaw power.
The foregoing and other features and advantages of the present invention will become more readily appreciated as the same become better understood by reference to the following detailed description of the preferred embodiment of the invention when taken in conjunction with the accompanying drawings, wherein:
