    摘要： A steering system for a riding lawn mower includes a wheel frame pivotally coupled to a vehicle frame about a roll axis. The wheel frame has spaced apart upper and lower wheel frame members. Steering knuckles are pivotally coupled to opposing sides of the wheel frame for rotatably supporting wheels. Each steering knuckle is straddle mounted between the upper and lower wheel frame members. A rack and pinion steering mechanism for pivoting the steering knuckles is coupled to a steering wheel via a steering column. The steering column includes a shaft portion extending along a shaft axis and has at least one socketed connection. The socketed connection transmits rotational movement about the shaft axis between the shaft portion and another rotatable component. The socketed connection also permits axial movement of the shaft portion along the shaft axis in response to the wheel frame rolling relative to the vehicle frame.

    摘要： An apparatus (10) for use in turning steerable vehicle wheels (12, 14) includes first and second piston and cylinder type hydraulic motors (32, 34) which are connected with a central portion of a vehicle. A steering control valve (24) is operable in response to manual rotation of a steering wheel (18) to effect extension and contraction of the first and second hydraulic motors. A rack and pinion steering gear (110, 114) may be connected with a piston rod (86) of one of the hydraulic motors (32). A secondary control valve (200) may be provided to effect operation of one of the hydraulic motors to a greater extent than the other hydraulic motor.

    摘要： A utility vehicle is provided with a bogey beam on which are mounted the steering axle at the forward end of the bogey beam and the middle axle on the rearward end of the bogey beam. A rear drive axle is supported by the frame of the utility vehicle. The bogey beam is connected to the frame by a pivot assembly defining a transverse pivot axis about which the bogey beam can oscillate. The weight transferred to the bogey beam is proportionately distributed between the front steering axle and middle axle. As a result, the steering characteristics of the steering axle are not impaired by the imposition of a load in the load bed of the utility vehicle, as the middle axle cannot be loaded sufficiently to overpower the front steering axle. The middle axle is rotatably driven by a chain drive transferring rotational power from the rear drive axle. The bogey, beam is provided with a plurality of pivot axis locations to vary the proportions of the load applied to the front and middle axles as a result of the longitudinal movement of the bogey beam pivot.

    摘要： A utility vehicle is provided with a middle axle that is mounted at the end of a bogey beam for flotational movement relative to the frame of the vehicle. The middle axle is restrained longitudinally by support links that are pivotally connected at a location forward of the rear drive axle. The middle axle is formed by a pair of stub axles interconnected by a support beam that is pivotally connected to the rearward end of the bogey beam. Vertical movement of the middle axle support wheels results in a corresponding vertical movement of the rearward end of the bogey beam and a rotation of the support beam about its pivotal connection on the bogey beam. The configuration of the support links provides sufficient slack in the drive mechanism to the middle axle during flotational movement thereof so as to allow a slight twisting of the drive mechanism during oscillation of the middle axle.
