A vehicle suspension system includes a frame, a damper and a rocker arm. The frame is connected with the rocker arm through the damper, the swing part of swing arm limits the swing arm's rotation angle by matching the limit structure on the frame; the bottom of damper is provided with the universal structure, the damper is connected with the rocker arm through the universal structure, and the universal structure controls the damper in free deflection. A deviation motion of vehicle wheels on both ends by coordinating the swing arm, vibration damper, etc. to avoid the slipping and rollover due to great sides way upon vehicle steering and the lateral wheels disengagement from ground and to enhance the safety of cornering driving of vehicles.

A suspension system for radio-controlled vehicles improves stability and traction. The suspension system includes a chassis, a motor pod plate, a shock absorption system, an upper pitch suspension link, a lower pitch suspension link, a left yaw suspension link, and a right yaw suspension link. The shock absorption system is used to reduce vibrations caused by impacts onto a radio-controlled vehicle. The upper pitch suspension link and the lower pitch suspension link allow the motor pod plate to pivot back and forth about a pitch axis of the chassis in order to increase stability and traction. The left yaw suspension link and the right yaw suspension link allow the motor pod plate to pivot back and forth about a yaw axis of the chassis in order to further increase stability and traction.

Disclosed is a mobile robot adapted to traverse vertical obstacles. The robot comprises a frame and at least one wheel positioned in a front section of the robot, at least one middle wheel positioned in a middle section of the robot, at least one back wheel positioned in a back section of the robot, and at least one further wheel in the front, middle or back of the robot. The robot also comprises at least one motor-driven device for exerting a downward and/or upward force on the middle wheel and at least two motors for driving the wheels and the motor-driven device. Also disclosed is a method of climbing using a mobile robot as disclosed.

Disclosed is a mobile robot adapted to traverse vertical obstacles. The robot comprises a frame and at least one wheel positioned in a front section of the robot, at least two middle wheels and at least two rear wheels. The at least one middle wheel and at least one rear wheel are connected by a tilting lever that is arranged on each of the opposing sides of or to the frame, forming a pair of wheels. Each tilting lever can be turned around a lever bearing located between the respective axial centers of rotation of each pair of wheels.

A vehicle comprising: a front wheel set and a rear wheel set, each set comprising two wheels and an axle attached to the said wheels; a base structure or chassis; a front elastic pivot structure, connecting the front wheel set to the chassis, wherein said front elastic pivot structure comprises a front set of at least one elastic joint, enabling the chassis to tilt along a front roll axis in respect to the said front wheel set; a front shock absorber, associated with the front wheel set; a rear elastic pivot structure, associated with the rear wheel set, wherein said rear elastic pivot structure comprises a rear set of at least one elastic joint, enabling the chassis to tilt along a rear roll axis in respect to the said rear wheel set; and a rear shock absorber, associated with the rear wheel set.
