Problems solved by technology

[0003] However, on the one hand, with the deterioration of the environment and the lack of resources, people pay more attention to and advocate "green energy", and the traditional hydraulic system will be gradually replaced by renewable energy. Therefore, the development of electromechanical brakes has a great impact on protecting the ecological environment. Significance; on the other hand, due to the shortcomings of the existing brake system, such as easy leakage of the hydraulic circuit, slow braking response speed, poor pedal performance, difficult assembly and maintenance, and difficult module integration, it has prompted people to develop a new generation of automotive brakes. system, the brake-by-wire system

Abstract

The invention discloses a vehicle electronic mechanical brake with a gap regulating function, which comprises a floating clamp body. The floating clamp body is provided with friction plates; an upper friction plate is fixedly arranged on the floating clamp body; a lower friction plate is connected with a force amplifier; a brake disc is arranged between the two friction plates; the force amplifier is connected with a motor; and the motor is used for pushing the friction plates by the force amplifier to ensure the friction plates adjacent to the brake disc so as to realize brake. According to the invention, under the action of a one-way clutch, a worm connected with a gear is driven by the gear to rotate and a worm gear is driven to rotate, so that a screw rotates relative to a nut fixed on the floating clamp body, and thus, the effect of regulating gaps is achieved and the gaps between the brake disc and the friction plates are freely regulated. Meanwhile, the self-locking property ofthe worm gear and the worm can also take a one-way moving effect. The vehicle electronic mechanical brake has both a force amplification effect and a gas regulating function, has simple structure, isconvenient to install and is easy to maintain.

Description

technical field [0001] The invention relates to an automobile braking system, in particular to an electronic mechanical brake for automobiles with the function of gap adjustment. Background technique [0002] As a ground vehicle, a car has three basic functions: driving, steering, and parking. The parking function is performed by the braking system of the car. "Safety, energy saving, and environmental protection" are the three themes of the future development of automobiles. As an important part of automobiles, the braking system directly affects the safety of automobiles. With the development of modern science and technology, at the same time, consumers' requirements for the safety performance of automobiles are increasing day by day, and the braking system of automobiles has also been continuously developed. Existing automotive braking systems are based on traditional hydraulic braking systems, implanted with ABS (anti-lock braking system), TCS (traction control system), ...
