Four-wheeler mechanism with adjustable eccentric distance

Abstract

The invention discloses a four-wheel vehicle mechanism with adjustable eccentricity, which comprises left and right wheels on both sides of the front part of the vehicle body and left and right wheels on both sides of the rear part, and the wheels include a wheel body and a wheel center adjustment assembly , the wheel center adjustment assembly includes a slide plate, a slide block and a drive motor for the slide plate, the slide plate is slidably arranged in the transverse sliding groove covering the wheel center of the wheel body on the back of the wheel body, and is installed through the transverse screw rod below and the transverse guide rod above In place, the screw rod is screwed into the screw hole at the lower part of the slide plate, the guide rod is penetrated through the guide hole at the upper part of the slide plate, and the drive motor of the slide plate is set on one side of the transverse slide groove and connected to the screw rod through a gear transmission pair; The slide block is slidably arranged in an oblique slide groove provided on the diagonal direction of the slide plate, and is installed and connected with the car body through the wheel shaft. The invention can run smoothly on complex terrain, not only reduces the bumping range of the four-wheel vehicle in the running process, but also improves the ability to overcome obstacles.

Description

Technical field [0001] The invention relates to a four-wheel vehicle mechanism, in particular to a four-wheel vehicle mechanism with adjustable eccentricity. Background technique [0002] With the rapid development of my country's nuclear industry, expedition and rescue, military investigation, fire fighting and explosives, aerospace and other fields, there is an urgent need for a device that can walk freely on flat ground as well as complex terrain such as earthquake ruins and mining disaster sites. And mobile robots that walk and cross obstacles freely in the environment. [0003] Existing mobile robots can be divided into: wheeled mobile robots, walking mobile robots (single-legged, double-legged and multi-legged), crawler mobile robots, crawling robots, creeping robots and swimming robots And other types. The wheel is recognized as the most efficient walking mechanism, due to its fast speed, high efficiency, simple structure, low motion noise, etc., it is durable. [0004] The ...

AI Technical Summary

Problems solved by technology

[0004] The wheel shaft of the ordinary four-wheel vehicle mechanism is fixedly installed at the wheel center of the wheel. During driving, it will not only produce bumps with the change of road conditions, but also have a sense of undulation and impact. The ability of obstacles is relatively small, far from meeting the requirements of stability and obstacle-surmounting ability
