Description

Technical Field

[0001] The utility model relates to an electronic parking caliper, in particular to an electronic parking caliper with more stable resetting. Background Art

[0002] The electronic parking caliper is a device used in modern cars to achieve parking brakes, which is used to clamp the brake disc to brake the vehicle. It replaces the traditional mechanical handbrake and realizes the parking brake function through an electronic control system.

[0003] When parking is required, the piston drives the friction plates to move toward each other, and the wheel disc is located between the friction plates. At this time, the friction plates and the wheel disc are against each other, thereby achieving the purpose of parking. When it is necessary to move again, the piston returns, and the friction plates are reset under the drive of the reset plate. At present, the position of the reset plate is unstable. When the friction plate and the wheel disc are against each other, deformation occurs. When it is necessary to move again, the deformation of the reset plate is reduced, thereby resetting the friction plate. During the deformation process of the reset plate, the position of the reset plate is unstable, which affects the subsequent reset of the friction plate. Utility Model Content
