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 booster braking system, in particular to an electric booster braking system with adjustable transmission ratio. Background technique [0002] In recent years, many countries have introduced restrictions on 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 comprehensive innovation. [0003] Since the electric booster brake system cancels the vacuum booster commonly used in traditional cars, and can realize the decoupling of friction braking force and regenerative braking force, and has simple structure and convenient layout, it will become an inevitable development of electric vehicle braking system. direction. [0004] At present, the development of electric power assist system mainly lies in the control method of motor power assist, and the power assist ratio of the power as...
