Description
Technical Field
The utility model relates to the field of brake calipers, in particular to a friction plate return mechanism.
Background
At present, when an automobile brakes, a piston is pushed by hydraulic pressure to further push a friction plate to clamp a brake disc, and when the automobile brakes, the friction plate is separated from the brake disc through the return of the piston and the centrifugal force generated when the brake disc rotates. However, due to the sliding resistance of the friction plate, the friction plate and the brake disc cannot be completely separated quickly when the brake is released, so that the dragging phenomenon is formed.
The method comprises the following specific steps: the head 51 of the brake caliper 5 is provided with an oil inlet hole, an oil pipe is connected with the oil pipe, brake fluid is filled in the oil pipe, when a pedal is stepped on by a foot, hydraulic pressure can be generated in a piston cylinder at the head of the brake caliper to push a piston outwards, the piston pushes a friction plate out again to enable the piston to be in contact with a brake disc, the friction plate is arranged on two sides of the brake disc, the friction plate 52 is in contact with the brake disc to brake, when the brake pedal is reset, the hydraulic pressure disappears, the brake disc has centrifugal force to throw away the friction plate, then a rubber ring for resetting is arranged in the cylinder head, and the piston is pulled back. The friction plate 52 is formed by connecting a friction block 2, a steel back plate 1 (steel back for short), a silencing plate and an alarm plate. In order to realize complete and quick separation, a return spring 3 is added to the large arc B on the outer edge of the steel back in the market as shown in figures 1, 2 and 3, the action of the return spring is to add a force on the basis of centrifugal force and rubber return force to help the steel back to return faster and better, otherwise dragging can be generated, and two ends of the return spring 3 are connected to the steel backs 1 of the two friction plates.
Referring to fig. 1 and 3, according to stress analysis, the deformation restoring force of a return spring received by a friction plate is located near a large arc B on the outer edge of a steel backing, and a point of the return spring 3 acting on the steel backing 1 is close to the outer side, so that the friction plate is very easy to deflect towards the inner side A, and a small arc C on the inner edge of the friction plate is in contact with a brake disc to generate eccentric wear and dragging phenomena, the service life of the friction plate is shortened, and the oil consumption or the power consumption of an automobile is greatly increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provides a friction plate return mechanism.
