A retractable wheel and/or track drive assembly for an amphibian comprising an actuator, a retraction linkage assembly movable between a protracted position and a retracted position, a suspension assembly at least partially connected to the retraction linkage assembly and movable between a protracted position and a retracted position, and at least one wheel and/or track drive, wherein when the retraction linkage assembly and the suspension assembly are protracted then the retraction linkage and/or suspension assembly supports and/or holds at least one wheel and/or track drive in a ground engaging position for use on land.

An off-road vehicle includes a frame, a front suspension, and a rear suspension. In some examples of the off-road vehicle, the rear suspension includes trailing arms with are pivotally attached to the frame rearward of an operator area. Further, the frame can include a front subframe assembly and a rear subframe assembly which are easily removable from the main frame of the vehicle to permit access to various components of the off-road vehicle.

A wheel module (10) for a motor vehicle includes a wheel (12) and a wheel guide (14) for guiding the wheel (12). The wheel guide (14) includes a wheel carrier unit (16) for supporting the wheel (12); a wheel fork (24) supporting the wheel carrier unit (16); a steering actuator (18) for adjusting the steering angle of the wheel (12); a spring-damper unit (28); and a level adjustment unit (36) for adjusting the height of the vehicle body (32) of the motor vehicle. The spring-damper unit (28) is arranged in a region of the wheel guide (14) between the wheel fork (24) and the wheel carrier unit (16).

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.

Embodiments relate to an off-road vehicle comprising a frame, including at least one cargo box support member, a suspension movably coupled to the frame, a passenger compartment, an engine, a transmission operatively coupled to the engine, and a cargo box. The cargo box includes a floor and a plurality of upwardly extending sidewalls, wherein at least a portion of the cargo box floor extends over the at least one cargo box support member and wherein the cargo box is removably coupled to the at least one cargo box support members and is removable from the off-road vehicle via the removal of fewer than eight fasteners.

The disclosure relates to a wheel module of a motor vehicle that includes a wheel and a steering lever assembly for a steering movement to the wheel. The steering lever assembly can be rotatably mounted on a support frame of the motor vehicle. A steering actuator for introducing a steering movement is connected to the steering lever assembly. The steering actuator is in the form of linear actuator. The steering lever assembly has a main lever connected to the steering actuator by means of a first connection region, and a steering lever connected to the main lever by means of an intermediate lever.

A suspension damping device installed at a chassis of a mobile robot comprises a vehicle frame, a controlling arm set and a damping device. The vehicle frame is fixed to the chassis and arranged on the ground. One end of the controlling arm set is hinged to the vehicle frame, and the other end of the controlling arm set is hinged to a steering device, so the controlling arm set controls the motion stability of the steering device. One end of the damping device opposite to the ground is hinged to the vehicle frame, and the other end of the damping device faced to the ground is hinged to the steering device. A six-wheeled bionic chassis which comprises a chassis frame, a controller, a sensor, front wheel suspension assemblies, middle wheel suspension assemblies and rear wheel suspension assemblies is also disclosed in the present invention.

An assembly for a wheel of a robotic vehicle and a method for overcoming an obstacle for said robotic vehicle. The assembly comprises a first arm portion and a second arm portion, the first arm portion being attachable to a chassis of the robotic vehicle at an attachment point and extending forwardly and downwardly relative to the attachment point in a direction of a movement of the robotic vehicle. The second arm portion is pivotably connected with the first arm portion at an arm pivot point and extends forwardly relative to the arm pivot point in the direction of the movement. The wheel is rotatably mounted on one end of the second arm portion opposed to the arm pivot point. A wheel rotation axis being positioned at least as high as the arm pivot point relative to a surface on which the robotic vehicle is positioned.
