Problems solved by technology

When the motor is decelerated by the reducer to drive the robot to walk, the unevenness of the ground will cause the wheels to vibrate, which will be directly transmitted to the robot chassis, resulting in particularly severe robot bumps
For a wheeled mobile robot with four or more wheels, if the two-wheel differential drive is used, due to the uneven ground, the driving wheel will be lifted by the driven wheel and cannot be driven.

Abstract

The invention discloses a suspension device for a wheeled mobile robot. Two first through holes used for two wheels (11) to penetrate through are formed in a chassis (1), two supporting bases (2) are fixedly arranged in the middle, between the two first through holes, of the chassis (1), are arranged oppositely and are each horizontally provided with two second through holes used for rotating shafts (6) to penetrate through, each rotating shaft (6) is fixedly connected with one end of the corresponding wheel support (7), the other ends of the two wheel supports (7) are connected with the two wheels (11) respectively, a gap is formed between the two wheel supports (7), and plate springs (4) are arranged at the opposite ends of the two wheel supports (7). The suspension device for the wheeled mobile robot relieves robot jolting caused by wheel vibration, improves driving stability of the robot, can adjust the distance from the driving wheels to the ground, and guarantees that the wheels touch the ground all the time.

Description

technical field [0001] The invention relates to a suspension device for a wheeled mobile robot, which belongs to the technical field of robots. Background technique [0002] In the wheeled mobile robot driving device, the driving wheel and the chassis are usually rigidly connected, that is, the wheel and the reducer are fixed on the wheel bracket, and the wheel bracket is directly fixed on the wheel chassis. When the motor is decelerated by the reducer to drive the robot to walk, the unevenness of the ground will cause the wheels to vibrate, which will be directly transmitted to the robot chassis, causing the robot to bump particularly seriously. For a wheeled mobile robot with four or more wheels, if a two-wheel differential drive is used, due to uneven ground, the driving wheel will be lifted by the driven wheel and cannot be driven. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method that can effectively...
