Abstract
A structure for three wheeled vehicles such that when the front handle bars are turned either the frame will be tilted in the direction of the turn or the wheels will be tilted parallely into the direction of the turn by providing in one form a means for rotatably mounting the frame upon a solid rear axle of the vehicle and in a second form by providing means to shift a pair of independent rotatably mounted axles to permit the wheels to be directed into the direction of the turn. In either situation the turning of the handle bars and the front wheel controls the attitude of the frame or the attitude of the wheels such that the unit will more easily corner or turn and thus decrease the possibility of tipping over.
Claims6
A tip over control for three wheeled vehicles, which vehicles include a front, rotatable steering wheel assembly, a frame assembly including a rearwardly positioned laterally extending frame portion, said control including:
- a. a rear axle pivotally connected, for movement about the longitudinal axis of the vehicle generally centrally to the lateral frame portion permitting the frame to shift relative to said axle;
- b. wheels rotatably mounted on the respective ends of said axle;
- c. linkage means including cable means having its ends operatively attached respectively to said axle on laterally spaced portions thereof and having its midsection wrapped about the steering assembly whereby the effective length of the cable means from said midsection to one of its axle connections will be lengthened when the steering assembly is rotated in one direction while the effective length of said cable means from its midsection to the other of its connections is shortened whereby the frame is shifted with respect to said axle upon rotation of the steering assembly said linkage means including;
- 1. a pair of lever elements rotatably mounted at their midpoints to the laterally extending frame portion and spaced outwardly from said axle connection;
- 2. the outer ends of said levers being attached to said axle;
- and,
- 3. said cable means being connected to the inner ends of said levers.
A tip over control for three wheeled vehicles, which vehicles include a front, rotatable steering wheel assembly, a frame assembly including a rearwardly positioned laterally extending frame portion, said control including:
- a. a pair of laterally and oppositely extending rear axle members rotatably connected respectively generally at their midpoints to laterally spaced portions of the laterally extending frame;
- b. wheel members rotatably arranged on the outer ends of said axle members;
- c. means for simultaneously controlling the position of said axles and thereby said wheels including linkage means extending from said rotatable steering wheel assembly to the inner ends of said levers to shift the same upon rotation of said wheel assembly.
