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

Embodiment Construction

[0047] Such as figure 1 As shown, the automotive electromechanical brake of the present invention includes a front side floating caliper 1 and a floating caliper body 7. The front side floating caliper 1 is connected to the front friction plate 23 through a friction plate support frame 24, and the front end of the floating caliper body 7 is connected through a nut piston 21. The rear friction plate 22, the brake disc 2 is arranged between the front friction plate 23 and the rear friction plate 22;

[0048] The nut piston 21 is fixedly connected with the floating caliper body 7, the nut piston 21 cannot rotate relative to the floating caliper body 7, and can only move axially together with the floating caliper body 7;

[0049] A sealing ring 20 may be provided between the nut piston 21 and the floating caliper body 7; or the piston cylinder of the nut piston 21 is a square section; or the nut piston 21 is provided with a sliding rod for guiding;

[0050] The nut piston 21 is c...

Abstract

The invention discloses an automobile electromechanical brake, which comprises a front floating caliper and a floating caliper block. The front floating caliper is connected with a front friction disc, the floating caliper block is connected with a back friction disc through a nut-piston, a brake disc is arranged between the front friction disc and the back friction disc, and the nut-piston is connected with a motor through a boosting linkage and is connected with a gap regulating mechanism. The motor pushes the back friction disc and the front friction disc to attach onto the brake disc by the boosting linkage, thereby realizing braking. The automobile electromechanical brake has a gap regulating function, and gaps among the brake disc and the friction discs can be regulated freely, so that constancy of the brake response speed of automobiles is guaranteed and braking performance is guaranteed further. The automobile electromechanical brake is fine in braking performance, simple in structure, convenient in installation, easy to maintain and low in energy consumption.

Description

technical field [0001] The invention relates to an automobile braking system, in particular to an automobile electromechanical brake. 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), ESP (electronic body stability system) and so...
