Abstract

The invention relates to an electronic mechanical brake, an electronic control pressure-maintaining mechanism thereof and a pressure-maintaining method. The electronic control pressure-maintaining mechanism comprises a motor, a self-locking nut and a gear hobbing sliding block, wherein the motor is connected with the self-locking nut; the self-locking nut is driven to move forward and backward respectively through forward rotation and reverse rotation of the motor; the gear hobbing sliding block is fixed on the self-locking nut and moves along with the movement of the nut; and the gear hobbing sliding block is provided with an occlusion device which is used for being mutually occluded and locked with an occlusion device of a brake motor.

Description

technical field

[0001] The invention relates to the field of automotive brake-by-wire, in particular to an electronically controlled pressure-maintaining mechanism for an electromechanical brake and a realization method. Background technique

[0002] Since the 1990s, some well-known manufacturers of automotive electronic components, such as Germany's Bosh, Siemens and Centinental Teves, have successively started research on EMB, and have done some corresponding system simulation and loading tests. In addition, Eaton, Allied, Signal, Delphi, Varity Lucas, and Hayes also participated in the R&D competition of EMB. However, domestic research on this project is basically blank. Only Tsinghua University has studied the EMB test bed, and Tongji University has trial-produced a prototype; other universities have only carried out some related preliminary research, and some core technologies have not yet been broken through. However, the present invention proposes the design of the e...
