Problems solved by technology

[0004] However, in the existing electromechanical braking system, the structure of the braking device is complex, it takes up a large space, and the manufacturing cost is high, so it is difficult to realize the application of loading in actual use.
For example, U.S. Patent US6405836 discloses an electromechanical brake, which has a complex structure and large radial size, and requires the design of a special torque motor, which is costly

Abstract

The invention provides an electronic mechanical braking device. The device comprises two friction plates (1, 3) arranged on two sides of a braking disc (2) respectively, and a braking execution mechanism which makes the two friction plates clamp the braking disc, wherein the braking execution mechanism comprises a ball screw mechanism and a power mechanism; the ball screw mechanism comprises a screw (4) and a nut (6) arranged on the screw; the screw (4) is connected with the output end of the power mechanism, and is driven to rotate by the power mechanism; and when the nut (6) on the screw makes linear motion on the screw (4), the nut (6) is contacted with the friction plate (3) arranged on one side of the braking disc. The electronic mechanical braking device has a simple and compact structure, small space occupying size and self-locking function, and can adaptively adjust the braking pressing force of the braking disc.

Description

technical field [0001] The invention belongs to the technical field of automobile wire-controlled braking in automobile manufacturing, and in particular relates to an electromechanical braking device. Background technique [0002] As consumers place increasing emphasis on vehicle safety, vehicle braking systems have undergone several changes and improvements. From the initial leather friction brake, to the appearance of drum and disc brakes, and then to the appearance of mechanical ABS braking system, followed by the development of electronic technology, analog electronic ABS braking system and digital electronic control system appeared. ABS braking system and so on. In the past 10 years, western developed countries have started to study the x-by-wire vehicle system, and then started the research on the electromechanical brake by the brake-by-wire system. Simply put, the electromechanical brake is to change the part of the brake system that was originally driven by hydraul...
