Abstract:
The disclosed articulated wheel assemblies and associated vehicles, for example wheelchairs, include articulated wheel assemblies with at least one offset connecting arm rotatably attached at one end to a payload platform, for example a seat, and attached at the other end to a linear actuator, where the linear actuator is further connected to a wheel. Embodiments include a rotary actuator for varying the linear actuator swing angle, a rotary actuator for eccentrically rotating a hubles wheel, a linear actuator motor for varying the length of the linear actuator, and a propulsion motor. Embodiments provide omnidirectional motion, stepping action when presented with obstacles, irregular surface negotiation, tight space maneuvering and other features to provide disabled people increased mobility.

Abstract:
The invention refers to a drive system for a wheel coupled to a chassis, comprising a rotary driving means, a rotary driven means and coupling means surrounding said rotary driving and driven means for transferring a driving force from said rotary driving means to said rotary driven means. What is provided according to the invention is that said wheel is movable laterally relative to said chassis from a first position to a second position, and said rotary driving and driven means are coupled to said wheel so that their angular orientations relative to the chassis change by the same amount when said wheel is moved from said first position to that second position.

Abstract:
A vehicle differential inversion assembly for splitting the torque of the vehicle power source two ways to opposite sides of the vehicle, to a set of wheels; a left wheel and a right wheel. The wheels are supported by respective independent left and right suspensions allowing vertical travel of each wheel. The assembly features a differential module for splitting the torque two ways. The differential module is disposed between the left wheel and the right wheel and has a left side output and a right side output. The outputs spin at opposed directions. A left output axle couples with the left side output and extends to the left of the differential module. A right output axle couples with the right side output and extends to the right of the differential module. A left wheel axle is cross-coupled with the right output axle by a right inversion joint disposed at a distance to the right of the differential module. The left wheel axle extends toward and turns the left wheel. A right wheel axle is cross-coupled with the left output axle by a left inversion joint disposed at a distance to the left of the differential module. The right wheel axle extends toward and turns the right wheel. The right inversion joint and the left inversion joint provide for angular articulation of the left wheel axle and the right wheel axle, respectively, thereby allowing the vertical travel of each wheel.

Abstract:
The invention relates to automobile construction. The technical effect of using it is to simplify construction, reduce the volume of metal required and increase the unit's reliability. The device contains brackets (2) attached to the side covers (4) of the reduction gear unit (1). The brackets (2) are secured by means of the threaded joints connecting the cover (4) of the reduction gear unit (1) with its housing. One end of each bracket (2) is connected via resilient connecting elements (6) to the support beam (5) of the steerable wheels' independent suspension system. The other end of each bracket (2) is connected via at least one resilient mounting (8) to the vehicle's lateral stabilizer. The brackets (2) can be mounted along the vehicle's longitudinal axis, in which case they are connected to the stabilizer (7) via two resilient mountings (8). The brackets can be bent in plan to form a fork-shaped unit, in which case the appropriate end of the bracket is connected to the stabilizer (7) via one resilient mounting (8). The resilient mounting (8) comprises a housing (9) and a cradle (10). The resilient connecting element between the brackets (2) and support beam (5) is in the form of a rubber bush (6).

Abstract:
A mechanical transmission group for transmitting motion from a central axis to four drive wheels of a large vehicle, in which the central axis is composed of two half-axles and has two drive half-shafts which transmit the motion to the wheels via appropriate mechanical transmissions. Each axle shaft (1 1 ) is connected in an oscillating or tilting way to a bearing structure that supports the wheels (3) by means of a slewing ring coupling (2). Each drive half shaft (5) is divided into several, mechanically connected, parts locked for rotation by means of sliding couplings and joints.
