Embodiment Construction

[0022] In order to better understand the present invention, the technical solutions of the present invention will be further described below in conjunction with examples.

[0023] Such as figure 1 As shown, a friction plate active return mechanism includes a fixed caliper, and the friction plate 1 located on both sides of the brake disc is installed on the fixed caliper. The fixed caliper can be single cylinder, double cylinder or multiple cylinders. This embodiment is double cylinder.

[0024] Such as figure 1 , 2 , 6, there are two return elastic parts between the two friction plates 1, and the two return elastic parts are symmetrically arranged at both ends of the upper part of the friction plate 1; the initial state of the two return elastic parts after installation is It is a compressed state with a certain initial elasticity.

[0025] Among them, the return elastic member preferably chooses a concave-shaped coil spring 3, and the concave-shaped coil spring 3 is a con...

Abstract

The invention belongs to the technical field of automobile disc brakes, and particularly relates to a friction plate active return mechanism of a fixed caliper. The friction plate active return mechanism includes two friction plates, a piston is arranged on the back of each friction plate, and two return elastic parts are arranged between the two friction plates; the two return elastic parts are symmetrically arranged at the two ends of the upper parts of the friction plates; the elastic force of an initial compression state of the return elastic parts is greater than the sliding resistance ofthe friction plates; when the friction plates are fully worn, the maximum elastic force of the return elastic parts is less than the sliding resistance of the pistons; and the bottoms of the pistonsare fixedly connected with the friction plates. The active return mechanism is additionally arranged on the basis of the fixed caliper, and the problem that friction plates in the prior art cannot bereturned automatically is solved. Through the active return, the friction plate can be returned faster and more in place, so that the drag torque is reduced, the unexpected wear of a brake disc and the friction plates is reduced, the fuel utilization rate and the service life of the friction plates are improved, and the occurrence rate of jittering is reduced

Description

technical field [0001] The invention belongs to the technical field of automobile disc brakes, and in particular relates to an active return mechanism for a friction plate of a fixed caliper. Background technique [0002] The friction plate of the existing fixed caliper disc brake has no active return function. When braking each time, the friction plate clamps the brake disc under the action of the piston to generate braking force to slow down or stop the vehicle; At this time, the piston returns first, and the friction plate is then thrown away from the brake disc by the rotation of the brake disc to realize the return of the friction plate. [0003] There are problems in the existing technology: the passive return of the friction lining causes the friction surface of the friction lining and the brake disc to wear faster, which reduces the life of the friction lining, and the excessive wear of the brake disc increases the occurrence probability of brake chatter, and this F...
