Title     The design of hybrid braking system for new energy Vehicles  

Abstract

Hybrid braking system is a combination of traditional hydraulic braking system and regenerative braking system.Transmission mechanism of braking force is a set of device to transmit braking energy from the pedal to the brakes,determining the braking performance of the hybrid braking system.

The paper discusses the composition of braking system,and analyzes the role of each component during the braking process,and investigates the methods of automobile braking system analysis and evaluation.The paper also study the force transmission mechanism of hybrid braking system of the new energy vehicle, to solve the problem found during the study，the paper puts forward three solutions, and design a kind of force transmission mechanism electro-hydraulic hybrid braking system based on linear motor braking, and analyzes its working principle and characteristics. Finally the paper make vehicle parameters of the Toyota Camry 2015 as design basis to design and calculate,determine appropriate parameters of master cylinder and wheel cylinder such as size and the brake pedal lever ratio.After being verified，the force transmission mechanism meet the regulation of braking.
