Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 Shown is a schematic diagram of the normal working state of the present invention. The highly integrated novel fully decoupled electro-hydraulic composite braking system is composed of an active pressure building module, a pedal feeling simulation module, a decoupling module and a brake wheel cylinder pressure regulating solenoid valve.

[0028] The active pressure building module is composed of a motor 3, a worm 4, a worm gear 5, a gear 7, a rack 8, a brake master cylinder 9 and a pedal displacement sensor 12, and the output shaft of the motor is connected with the worm 4, and the One end of said gear 7 is an optical axis, and one end has teeth, and the optical axis of this gear is connected with the center hole of worm wheel 5 by a key.

[0029] The brake master cylinder 9 is divided into front and rear cylinder cham...

Abstract

The invention relates to a highly-integrated novel fully-decoupled electric-liquid compound braking system, which comprises a motor, a worm wheel, a worm, a gear, a rack, a braking master cylinder, a pedal, a pedal displacement sensor, a secondary master cylinder, solenoid valves, a decoupled cylinder, a pedal simulator, a pressure sensor, a liquid storage tank, a pipeline and the like. According to the fully-decoupled electric-liquid compound braking system, the motor and a turbo-worm mechanism are adopted as power to brake, so that the pedal and the braking master cylinder can be fully decoupled; through a simple control method, the six solenoid valves are used to mutually cooperate to realize the functions such as ABS (Anti Lock Braking System) and ESC (Electronic Stability Control), the structure is simple and compact, a high pressure accumulator is cancelled, the potential safety hazard is reduced, meanwhile, the braking is fast, the control is accurate, and the mechanical connection also effectively ensures the safety and the reliability of automobile braking.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to automobile braking technology, in particular to an electro-hydraulic composite braking system driven by a motor and provided with mechanical failure protection control. Background technique [0002] Petroleum resources are a kind of non-renewable resource energy. With the continuous improvement of people's living standards and the continuous increase of the number of cars, the consumption of petroleum is constantly increasing. While the energy is decreasing, it has also brought many serious problems to the society. Environmental and energy issues, so energy-saving and environmentally friendly electric vehicles have become the subject of research and research, and are also the trend of future automotive development. On urban roads, especially in large cities, the braking of automobiles is quite frequent, and the energy consumed thereby accounts for a large part of the total ener...
