A mechanical leg comprises a frame, a retractable member, a wheel, an extension and retraction driving member, a travel driving member, an auxiliary leg, and an auxiliary wheel. The extension and retraction driving member is located on a side of the frame. The retractable member is connected to the extension and retraction driving member. The wheel is connected to the retractable member. The wheel is further connected to the travel driving member. A first end of the auxiliary leg is connected to the auxiliary wheel, and a second end of the auxiliary leg is located on the frame. The retractable member extends under the driving of the extension and retraction driving member to drive the wheel to jump. The wheel is driven by the travel driving member to move. When the auxiliary wheel contacts the ground, the mechanical leg moves with the rolling of the wheel and the auxiliary wheel.

A strut assembly including a reservoir tube that extends about and along a center axis and has an interior surface and defines a chamber. A bearing sleeve is disposed in the chamber of the reservoir tube and extends about and along the center axis between a proximal end and a distal end. The bearing sleeve presents an inner surface and an outer surface. A damper body tube is disposed in the bearing sleeve and is moveable relative to the bearing sleeve. A piston assembly is disposed in the damper body tube. The outer surface of the bearing sleeve has a tubular portion and a protrusion portion that extends radially outwardly relative to the tubular portion and annularly and providing an interference fit between the outer surface of the bearing sleeve and the interior surface of the reservoir tube.

A vehicle is provided including an electronic power steering system, an electronic throttle control system, and a stability control system.

A coilover shock absorber includes a damper element and a coil spring, where the coilover shock absorber includes a first mount for the damper element and a second mount for the damper element, and where the coilover shock absorber includes a first seat for the coil spring and a second seat for the coil spring, where the first mount for the damper element is operatively separate from the first seat for the coil spring, where the second mount for the damper element is operatively separate from the second seat for the coil spring. The resulting inverted coilover shock absorber allows for separate load paths for the damper element and the coil spring to the chassis.

An adjustable suspension mount assembly includes a bracket coupled to a suspension mounting component and coupled to a frame component of the vehicle. The assembly also includes a vertical adjustment assembly operatively coupled to the bracket. The assembly further includes an electric motor operatively coupled to the vertical adjustment assembly to adjust the vertical position of the bracket.
