Problems solved by technology

The use of this chassis has the following disadvantages: (1) The motor of the whole vehicle is fixed on the PCB, the bearing capacity of the whole vehicle is very small, and it cannot bear heavy objects
(2) The motor directly drives the wheels, and the radial bending moment of the motor directly acts on the motor shaft, which is easy to damage the motor or cause the wheels to appear external or internal.
(3) The steering of the whole vehicle is realized by the differential speed of the motor. It is inevitable that there will be a turning radius during the driving and turning process, and there will be some driving blind spots, which cannot achieve full road coverage.

Abstract

The present invention provides a four-wheel eight-drive robot chassis mechanism, comprising a chassis, four steering devices, and four driving devices. Each steering device comprises a steering motor, two steering motor fixing plates, a connecting plate, a synchronous belt, two synchronous belt wheels, a synchronous belt wheel connecting flange, a steering bearing, a steering bearing sleeve, and a fixing plate. Each drive device comprises a tire, a hub, a drive motor, a motor fixing plate, a hub connecting column, a hub connecting plate, and a motor output shaft fixing block. Each fixing plate is connected with a steering connecting block. The steering connecting block is fixedly connected withthe motor fixing plate, and the motor fixing plate is perpendicular to the steering connection block. The four-wheel eight-drive chassis mechanism can achieve zero turning radius, full-drive and all-direction, andflexible movement. Each wheel train is independent as a self-system, which is convenient to assemble into other driving modes. The structural parts of the wheel train are mostly plates or profiles, which are low in price and convenient to assemble.

Description

technical field [0001] The invention relates to the technical field of a robot chassis mechanism, in particular to the technical field of a four-wheel and eight-drive robot chassis mechanism. Background technique [0002] As a modern new invention, the smart car is the future development direction. It can automatically operate in an environment according to the preset mode, without human management, and can be used for scientific exploration and so on. The smart car can display time, speed, and mileage in real time. It has functions such as automatic tracking, light finding, and obstacle avoidance. It can be programmed to control driving speed, accurately locate parking, and remotely transmit images. [0003] As the most basic and core chassis mechanism of the smart car, it supports and carries other parts of the whole car, forms the style of the whole car, transmits the power of the motor, and ensures the normal driving of the whole car; and its structure also determines th...
