An electric power-assisted braking system with adjustable transmission ratio

Abstract

The invention discloses an electric power-assisted brake system with an adjustable transmission ratio. The system comprises a shaft I, a shaft II, a hollow shaft, a main cylinder and a control device,wherein the shaft I and the shaft II are symmetrically arranged on two sides of the hollow shaft; one end of the shaft I is connected with a motor I; a low-speed gear I and a high-speed gear I are fixedly connected onto the shaft II and synchronously rotate with the shaft II; a low-speed gear II is connected with the position, corresponding to the low-speed gear I on the shaft II, of the hollow shaft in a sleeving manner; the low-speed gear I is meshed with the low-speed gear II; a high-speed gear II is connected with the position, corresponding to the high-speed gear I on the shaft II, of the hollow shaft; the high-speed gear I is meshed with the high-speed gear II. The system has the beneficial effects as follows: functions of driving brake, actual effect backup and the like can be realized, and an active control technology can be integrated, so that intelligent control for a vehicle is realized; the system is good in portability and facilitates test experiments of external equipment.

Description

technical field [0001] The invention relates to an electric power-assisted braking system, in particular to an electric power-assisted braking system with an adjustable transmission ratio. Background technique [0002] In recent years, many countries have introduced plans to limit the sale of fuel vehicles, so electric vehicles will usher in a wave of development in recent years. With the rapid development of electric vehicles, many traditional automotive systems will usher in a comprehensive innovation. [0003] Since the electric power-assisted braking system cancels the vacuum booster commonly used in traditional vehicles, and can realize the decoupling of frictional braking force and regenerative braking force, and has a simple structure and convenient layout, it will become an inevitable trend in the development of electric vehicle braking systems. direction. [0004] At present, the development of the electric power assist system mainly lies in the control method of ...
