Spring piece device capable of enabling friction piece to automatically return

Abstract

The invention belongs to the technical field of mechanical braking, and relates to a device for reducing dragging force of calipers, particularly to a spring piece device capable of enabling a friction piece to automatically return. The spring piece device comprises a friction piece assembly, a spring piece, a bracket, a caliper body and a piston, wherein the piston is mounted in a cylinder hole of the caliper body; the bracket is fixedly connected with the caliper body; the spring piece is fixedly mounted on the bracket; the friction piece assembly is mounted on the spring piece; clamping grooves and buckles are arranged on the bracket; the spring piece is connected between the clamping grooves and the buckles in a clamping manner; an automatic return mechanism is arranged on the spring piece; and one end of the automatic return mechanism and one end of the spring piece are in circular arc transition connection. According to the spring piece device, the spring piece is changed into split type, and the automatic return mechanism is added on the spring piece, so that the problems that the spring piece cannot be utilized in common and the friction piece cannot timely return in projects of brake discs with different thicknesses.

Description

technical field [0001] The invention belongs to the technical field of mechanical braking, and relates to a device for reducing the dragging force of a caliper, in particular to a spring device for actively returning a friction plate. Background technique [0002] In recent years, people's awareness of energy saving and emission reduction has been strengthened. OEMs also have higher requirements for the drag torque of caliper manufacturers. The function of the caliper is to decelerate or stop the car through the friction between the friction plate and the brake disc. The caliper is one of the key safety parts of the car. [0003] Taking the one-piece caliper as an example, the bracket is installed on the horn, the spring piece is stuck on two recesses on one side of the bracket, the friction plate is installed on the spring piece, and the housing assembly is connected to the bracket through guide pins. When the same type of spring is applied to brake discs with different t...

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to provide a spring device for actively returning the friction plate. By changing the spring to a split type, each depression of the bracket is equipped with a spring respectively, and an active return mechanism is added to the spring , to solve the problem that the spring plates cannot be shared and the friction plates cannot be returned in time in the project of brake discs of different thicknesses
