A portable towing system for a motorcycle or similar vehicle, such as a trike, the frame of which can be lowered to ground level to facilitate loading of the motorcycle or similar vehicle by pushing or riding the vehicle onto the frame without risk of the vehicle falling off the sides of a steeply inclined ramp. The towing system may be assembled, raised, lowered, and disassembled by a single person, if desired. The raising and lowering of the frame is effected by a lifting and lowering mechanism connected with the wheel assemblies.

A chassis for an electrically powered vehicle, including a front wheel suspension and a rear wheel suspension, each having longitudinal control arms arranged on both sides and a torsion spring actively connected to the longitudinal control arms. The chassis includes a battery housing receiving a propulsion battery. A front transverse carrier extends between the respective longitudinal control arms of the front wheel suspension, and a rear transverse carrier extends between the respective longitudinal control arms of the rear wheel suspension. The respective transverse carriers are rigidly connected to the battery housing and couple the longitudinal control arms and the torsion spring.

A universal axle-hub assembly is provided for an off-road vehicle. The universal axle-hub assembly comprises a wheel hub that receives a constant velocity (CV) axle snout into an opening extending through an axle support of the wheel hub. An outboard-most portion of the opening is a splined portion that engages with similar splines disposed on an outboard-most portion of the CV axle snout. An inboard-most portion of the opening is a smooth portion that receives a smooth portion of the CV axle snout. The axle support extends through an entirety of the width of a bearing that supports the wheel hub, such that the bearing supports the smooth portion of the CV axle snout and substantially eliminates shear forces acting on the splined portion of the CV axle snout. A bearing carrier supports the bearing and may be fastened onto a trailing arm or a spindle of the off-road vehicle.

A low suspension arm strut coupling is provided for a suspension of an off-road vehicle. The suspension comprises a lower suspension arm that is hingedly coupled between a chassis of the off-road vehicle and a spindle assembly that is coupled with a front wheel. An upper suspension arm is hingedly coupled between the chassis and the spindle assembly. A strut is coupled between the lower suspension arm and the chassis. A lower pivot couples the strut to the lower suspension, and an upper pivot couples the strut to the chassis. The upper and lower pivots provide a lower center of gravity of the off-road vehicle and a relatively smaller shock angle. The lower suspension arm is reinforced to withstand forces due to movement of the front wheel and operation of the strut in response to travel over terrain.

The present invention relates to a modular way to build a rolling chassis using composite materials without custom forming, and yielding appropriate weight distribution (centre of gravity) and torsional and bending rigidity.

A finish machined rear pivot support a dump body of a haul truck can comprise a pair of rear pivots spaced apart from each other in a first direction, and a cross-member extending in the first direction between the rear pivots. The rear pivots can be respectively welded in-line with longitudinal support body members on a bottom of the dump body. The cross-member can extend from inward-facing sides of the rear pivots. Each of the rear pivots can include two cut-outs spaced apart from each other in a second direction perpendicular to the first direction. The cut-outs can be provided over corresponding one of transverse support body members on the bottom of the dump body.

An information processing apparatus disclosed has a controller configured to execute the processing of accepting a request for retrieving a target vehicle body unit that is laid at a specific place, selecting a chassis unit for retrieval from among chassis units in the state separated from any vehicle body unit, the chassis unit for retrieval being a chassis unit to be used to retrieve the target vehicle body unit, and sending a retrieval command to the chassis unit for retrieval, the retrieval command being a command to retrieve the target vehicle body unit.
