An additional wheel weight for a utility vehicle includes a weight plate and a retention member configured to be fitted to a wheel rim and on which the weight plate is guided in a longitudinally axial manner. A clamping lever closure is disposed between the weight plate and retention member. A first assembly element of the clamping lever closure is coupled to the retention member, a second assembly element of the clamping lever closure engages the weight plate in a longitudinally axial manner, and a lever mechanism is disposed between the first and second assembly elements. The lever mechanism includes a clamping element being releasably secured to the first assembly element and an actuation lever being articulated between the second assembly element and the clamping element.

Vehicles are disclosed that are configured to carry loads in a stabilized manner, such that the load is maintained in a substantially constant position or orientation relative to a predetermined reference point or frame even as the vehicle moves. A stabilization controller in such a vehicle receives information about movement of the vehicle relative to the reference point or plane from one or more sensors on the vehicle, and uses the information to control one or more movable objects by which the load is secured to the vehicle so as to maintain a relatively constant relationship between the load and the reference point or plane.

A wheel includes a circular wheel main body and at least one grouser. The at least one grouser is provided along an outer circumference of the wheel main body and has a contact surface capable of drawing a first tangent line. The first tangent line is inclined opposite to a rotational direction of the wheel main body from the center line of the wheel main body.

A circular wheel is aligned in a rotational plane and has a peripheral outfacing surface symmetrical about the plane of rotational. A center line of the width of the peripheral outfacing surface is sinusoidal around the wheel. The wheel may have a central hub, a rim, a medial wheel structure between the hub and the rim, and a tire mounted on the rim. The outfacing surface may be that of the hub, the medial wheel structure, the rim, or the tire depending on the application.

Disclosed is a method of forming a wheel assembly consisting of a wheel portion and a cover portion. The method includes handling the wheel portion from dunnage to a work cell with an outboard face of the wheel portion facing away from a supporting surface. Next, determining a planar position and a rotational position of wheel portion and retrieving the cover portion. The method proceeds with applying an adhesive to at least one of the back side of the cover portion and the outboard face of the wheel portion. Then, aligning the cover portion with the wheel portion utilizing the planar position and the rotational position. The next step is engaging the cover portion and the wheel portion with one another and maintaining the wheel portion in engagement with the cover portion for a predetermined amount of time with a predetermined amount of pressure to form the wheel assembly.

The present disclosure belongs to the technical field of walking mechanisms, and provides a smooth obstacle-crossing walking mechanism, which can provide strong smooth obstacle crossing capability, meanwhile, maintains lower friction loss and higher efficiency, and is suitable for most daily use situations. A smooth obstacle-crossing walking mechanism includes a driving wheel and a contact wheel. The driving wheel has a wheel diameter lower than that of the contact wheel. The driving wheel compresses an inner edge of the contact wheel under gravity. The contact wheel is in contact with the ground surface. When the driving wheel rotates actively, it walks along the inner edge of the contact wheel under the frictional force with the contact wheel. The contact wheel rolls forwards under a pressure and the frictional force of the driving wheel, so as to enable the smooth obstacle-crossing walking mechanism to walk.

A driving device for a carriage includes a motor, a speed reducer, and a first mecanum wheel and a second mecanum wheel. The speed reducer decelerates the rotation input from the motor and outputs decelerated rotation. The first and second mecanum wheels are arranged in the axial direction parallel to the rotation axis of the decelerated rotation output from the speed reducer and are rotated by the decelerated rotation output from the speed reducer. In the axial direction, the center of the speed reducer is positioned between an outer end of the first mecanum wheel opposite to the second mecanum wheel and an outer end of the second mecanum wheel opposite to the first mecanum wheel.
