    摘要: A steering assembly for a utility vehicle having a support frame. The assembly includes a fluid-powered rotary actuator, with a body having a rotatable hollow shaft extending therewithin. An annular piston is mounted within the body about the shaft for reciprocal axial movement and rollers are provided for transmitting torque between the body and the shaft to produce rotational movement of the shaft in response to axial movement of the piston. An axially extendable member extends longitudinally within a central bore of the shaft with a lower end portion projecting out of the body and being attached to forks to which a wheel is rotatably mounted. The central bore of the shaft and the extendable member have meshing straight splines which transmit the rotational drive of the shaft to the extendable member, while allowing free axial movement of the extendable member. The extendable member has a piston portion which defines an interior fluid chamber. An accumulator is in fluid communication with the fluid chamber. The fluid chamber is filled with hydraulic oil, as is a portion of the accumulator. The remainder of the accumulator is filled with compressible nitrogen gas. The extendable member piston portion moves upwardly within the central bore in response to upper movement of the wheel to transmit the force of the upward movement through the hydraulic oil to the compressible fluid for absorption of at least a portion of the transmitted force.

    摘要: The present invention relates to a structure with multiple independent wheels for cycles or engine-driven vehicles which run on an irregular bearing surface. The structure is comprised of two twin wheels (10, 11) which are interconnected by two toggle-levers (12). Each of the two wheels (10 and 11) is comprised of a central part (13) and a peripheral part (14). The central part is fixed and the peripheral part rotates and is concentric with the central part. Both parts (13 and 14) are coupled to each other by a crown-shaped roller bearing (15) which is comprised of an inner annular element (16) and a rotary outer annular element (17). The two levers (12) are connected to the suspension by arms (20). The device provides an optimum adherence to road surfaces.

    摘要: A steerable fork mount that is pre-assembleable and compact comprising a fork having a top and two depending pedestals that are rigidly formed together, that are relatively short in the fore and aft direction, with a rocker beam at the bottom, rockable about a vertical stub shaft supported on each pedestal and providing an arrangement to support a spring mounted between the rocker beam and the pedestal, and with an arrangement to make the pedestal structure extremely rigid and strong, particularly in the transmission of the displacement forces from the wheel to the spindle mount.

    摘要: A shock absorbing wheel suspension for vehicles in which the ground engaging wheel is mounted for limited vertical and horizontal movement relative to a base by forward and rear wheel support brackets that are pivotally interconnected at their adjacent ends on the wheel axle and which are pivotally supported at their outer ends for vertical swinging and horizontal shifting movement on forward and rear suspension brackets pivotally connected to the base. Forward and rear spring assemblies are arranged to engage the forward and rear wheel support brackets to yieldably bias the wheel support brackets angularly in a direction to oppose upward movement of the wheel assembly and to also yieldably bias the forward and rear wheel support brackets horizontally in relatively opposite directions to a centered position. The mounting base is adapted to be supported for turning movement about an upright axis vertically aligned with the wheel axis when the latter is in its centered position to provide a steerable wheel assembly.
