Abstract

The invention discloses an electronic mechanical brake with a parking function. The electronic mechanical brake comprises a parking braking mechanism and a service brake. The parking braking mechanism is used for achieving the parking function and comprises a torque motor, a spline, a tension spring, an electromagnetic push rod, a parking energy storage spring, a pin, a pin spring, a parking ball screw mechanism, a parking pressing rod, a parking push rod and the like. The service brake is used for completing service braking and comprises a speed reducing and torque increasing mechanism, a motion conversion mechanism, an automatic gap adjusting mechanism, a caliper body, a brake disc, a brake block, a brake friction plate and the like. The automatic gap adjusting mechanism is used for achieving automatic adjustment of the brake gap when the brake friction plate is abraded and comprises a transmission bolt, a two-jaw rotating wheel, a three-jaw rotating wheel, a chain wheel and a chain. The problems that an existing electronic mechanical brake is uniform in braking force distribution, low in braking reliability, slow in braking response and the like are solved, and the functions of automatic gap adjustment and parking braking can be achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile brake safety, and relates to a structure of an electromechanical brake with a parking function. Background technique [0002] With the development of society and the advancement of technology, cars are gradually evolving towards intelligence and electronics. Due to the shortcomings of slow braking response, complex overall structure, large overall size, and hydraulic hysteresis, the traditional hydraulic braking system has been unable to meet the requirements of lightweight, electronically controlled, and intelligent vehicles. As a brand-new braking system, the electromechanical braking system uses the motor as the power source and replaces the complex mechanical pedal with the electronic pedal. It has the advantages of simple structure, small size, fast response speed, high control precision, energy saving and environmental protection, etc. It has become a research hotspot. [0003] At prese...
