Abstract

The invention discloses an adjustable suspension device for a heavy-duty wheeled robot, which comprises a suspension support, on which a fixed end of a guide device is arranged; Support, the lower end is only supported by the lead adjustment block; the lead adjustment block is installed in the lead adjustment block mounting hole of the suspension support, and can move along the lead direction. The suspension device of the present invention can change the ground clearance of the robot, increase the passability of the chassis, and improve the ability to pass through the bottom of the vehicle or obstacle by changing the compression amount of the spring of the suspension and the relative position of the upper and lower vertices of the spring; Potholes on the road where the robot actually operates can increase the suspension stiffness and improve the robot's ability to maintain posture when moving on uneven roads; the suspension device of the present invention is especially suitable for ultra-thin wheeled robots.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to an adjustable suspension device for a heavy-duty wheeled robot. Background technique [0002] Current wheeled robots mainly use flexible materials such as rubber or a fixed spring to achieve shock absorption. The prior art can only perform barrier and shock absorption to a certain extent, but cannot achieve a more accurate adjustment of the up and down stroke of the suspension. Contents of the invention [0003] The object of the present invention is to provide an adjustable suspension device for a heavy-duty wheeled robot aiming at the deficiencies of the prior art. [0004] The purpose of the present invention is achieved through the following technical solutions: an adjustable suspension device for a heavy-duty wheeled robot, including a suspension support, a fixed end of a guide device is arranged on the suspension support, and the mobile end of the guide device...
