Title The design of military vehicles electronic parking brake system actuator Abstract Automotive Electronic Parking Brake (EPB, Electronic Parking Brake) is to improve the maneuverability of vehicle and Parking safety and developed a wire control device. Automotive electronic parking brake system are analyzed the development background, domestic and foreign development present situation, trend and significance, and analysis of automotive electronic parking brake system composition, working principle, advantages and difficulties. Research to meet military vehicles under full load condition to the central disc parking brake reliably is parked on a 60% slope. Design a military vehicle electronic parking brake system overall scheme, detailed analysis of the stress of the military vehicle, design a military vehicle key mechanical execution components, including motor selection, the design of the speed reducer, ball screw vice parts selection, to slow down the related parts and the ball screw vice related check. Twisting the reducer's main function is to slow down, ball screw implementation is to put the gear reducer rotation movement into linear motion, through the cable to realize the safety of the car parking, heritability has realized the electronic parking brake system has the function of the expected design.
Key words： Electronic parking brake system The central disc parking brake Gear reducer Ball screw vice
