Mecanum wheel omnidirectional vehicle active suspension device

The invention provides a Mecanum wheel omni-directional active suspension device for a vehicle. The Mecanum wheel omni-directional active suspension device comprises an active suspension, a laser sensor and a pose sensing controller. The active suspension is connected with the Mecanum wheel driving wheel set and then installed on the frame. During working, the active suspension does reciprocating rectilinear motion in the vertical direction, and when the pose sensing controller detects that Mecanum wheels are in poor contact with the ground, the length of a push rod of the suspension actuator is actively adjusted, and the inclination degree of a vehicle body is monitored until the wheels are in reliable contact with the ground and the vehicle frame is driven to return to the horizontal state; in the whole process, the wheel base and the wheel track of the omni-directional vehicle are not changed, so that the omni-directional movement performance and the operation precision of the omni-directional vehicle are guaranteed at the same time. The active suspension can also automatically adjust the ground clearance of the vehicle frame as required, and the trafficability and the driving stability of the omnidirectional vehicle are both considered. In addition, due to the arrangement of a guide mechanism limiting device and a rubber cushion block, all parts of the active suspension can be prevented from being damaged due to outrange and generating rigid collision.
