Problems solved by technology

[0004] However, in this electric brake, only a brake nut is driven by a motor to press a friction plate on the brake disc to achieve braking. Because the friction plate is not directly connected with the brake nut, and the brake disc is Circumferential rotation will occur, and when the brake nut pushes the friction plate against the brake disc, as the brake disc rotates, the friction plate will easily deflect around the action point of the brake nut, thus causing the friction plate to In the case of eccentric wear, the braking effect is poor; and it is difficult to determine whether the braking force of the friction plate is sufficient when the electric brake is braking. After long-term use and wear of the friction plate, insufficient braking force is prone to occur, resulting in poor braking effect and poor braking response. Slow speed or even brake failure

Abstract

The invention provides an electric brake and belongs to the technical field of vehicle braking. By adopting the electric brake, the problem that an existing electric brake is poor in braking effect issolved. The electric brake comprises a drive device, a brake lining, a brake disc and a first push rod arranged between the drive device and the brake lining. A second push rod is further arranged between the drive device and the brake lining. The first push rod and the second push rod are in transmission connection with the drive device, and can be driven by the drive device so as to drive the brake lining to abut against the brake disc. The electric brake further comprises two pressure sensors and a controller. The two pressure sensors can detect the amplitudes of braking force applied to the brake lining by the first push rod and the second push rod correspondingly, and send information of the braking force to the controller. The controller can receive the information of the braking force of the pressure sensors and controls driving force output by the drive device. The electric brake has the advantage of good braking effect.

Description

technical field [0001] The invention belongs to the technical field of vehicle braking and relates to an electric brake. Background technique [0002] The braking system is an important part of the car, and the braking devices of most existing cars are hydraulic brakes. When braking, the driver controls the hydraulic brake master cylinder through the pedal to pressurize through the vacuum booster, and transmits it to the brake cylinders of each wheel through hydraulic pipelines to perform hydraulic braking on the disc brakes. However, during the use of the hydraulic braking system, due to the use of hydraulic pipelines for braking force transmission, oil leakage is prone to occur and the response speed is slow. [0003] For this reason, people have designed a kind of electric brake and have applied for Chinese patent (its application number is: 200820226958.2; Its announcement number is: CN201326669Y), this electric brake comprises brake caliper, brake cylinder and brake cy...
