Abstract

The invention discloses a variable-impedance Mecanum wheel posture keeping mechanism which comprises a front axle, a rear axle, a front and rear axle hinge connector, a left front Mecanum wheel, a right front Mecanum wheel, a left rear Mecanum wheel, a right rear Mecanum wheel, a left parallelogram mechanism, a right parallelogram mechanism, a left variable-impedance elastic device, a right variable-impedance elastic device, a frame and a rotation shaft. The variable-impedance elastic device can ensure that a car can adapt to different loads. The variable-impedance Mecanum wheel posture keeping mechanism can not only solve the problem of keeping simultaneous wheel landing and advancing of a Mecanum vehicle on the uneven ground, but also can ensure that the wheels are always perpendicular to the ground where the wheels are located, further ensure that the conditions of contact with the ground of the wheels are the same, and accordingly ensure the movement performance.

Description

technical field

[0001] The invention relates to the field of structural design of a Mecanum wheel trolley, in particular to a variable impedance Mecanum wheel attitude maintaining mechanism. Background technique

[0002] The Mecanum wheel (also known as the Swedish wheel) is a special wheel train proposed by the Swiss engineer BengtIron. The peripheral edge of the hub is equipped with a roller that is at a certain angle to the central axis and can rotate around its own axis. When the wheel rotates on the ground, the stick The oblique force generated by the interaction with the ground drives the wheels to move along the oblique direction. The Mecanum-wheeled trolley has omnidirectional movement characteristics and high precision. It can easily shuttle in narrow and crowded spaces, and flexibly complete various tasks. Compared with traditional mobile platforms, it has obvious advantages. However, due to the special structure of the Mecanum wheel, the wheels need to be in cons...
