电驱动无人履带车辆线控机电联合制动技术研究

The electric drive tracked vehicle has good motion controllability, and the problems of heavy load and short life of brake system for the traditional tracked vehicle can be relieved by means of electric brake, which is an ideal driving method for realizing the unmanned driving of tracked vehicle. Through the design of braking system for an electric drive unmanned tracked vehicle, a complete technical solution for the electro-mechanical combined braking system is proposed, which is totally controlled by wire. An improved three-stage mechanical-electric brake combination method is adopted, and according to the principle of maximizing braking energy recovery under the premise of ensuring the custom dynamic performance, a corresponding mechanical-electrical braking force distribution strategy is given. After the platform was built according to the scheme, the brake performance test was carried out. The test results show that the system has good braking performance and stability, and can fully meet the requirements of the national military standard for the braking performance of military tracked vehicles while ensuring the kinetic energy conversion efficiency being around 25%.
