Six-wheeled independent drive chassis system for unmanned vehicle

Abstract

The invention relates to a six-wheeled independent drive chassis system for an unmanned vehicle. The chassis system comprises a frame, suspension systems, transmission devices and motor speed reducer assemblies, and is characterized in that: the frame comprises two longitudinal beam parts which are eudipleural, and three transverse beam modules which are parallelly arranged back and forth; the three transverse beam modules are fixedly connected between the two longitudinal beam parts; six groups of suspension systems are connected to the longitudinal beam parts of the frame; each group of suspension system comprises a suspension system, a braking system and a driving system; six groups of transmission devices are arranged on the suspension systems; and six groups of motor speed reducer assemblies are fixedly arranged on the three transverse beam modules of the frame in pairs, and are connected with and drive the driving systems of the suspension systems through the transmission devices. The chassis system is high in modular degree, has the advantages of simple structure and high shock absorption property, is convenient to assemble, disassemble and maintain, can be applied to the unmanned vehicle and can be used as the chassis structures of other electric automobiles.

Description

technical field [0001] The invention relates to a vehicle chassis device, in particular to a six-wheel independently driven chassis system for an unmanned vehicle, which belongs to the technical field of automobiles. Background technique [0002] In terms of structure, a car can be divided into two parts: the chassis and the body. Automobile chassis refers to other parts other than the body, including the chassis frame equivalent to the skeleton of the automobile, the driving device, the braking device and other necessary devices for driving. A pure electric vehicle is a vehicle that uses a battery as a power source for energy storage. It uses a battery as a power source for energy storage, and supplies electric energy to the motor through the battery to drive the motor to run, thereby propelling the car forward. From the appearance point of view, electric vehicles are no different from ordinary cars that we see every day. The main difference lies in the power source and it...
