Background
At present, when an automobile brakes, a piston is pushed by hydraulic pressure so as to push a friction plate to clamp a brake disc, and when the automobile brakes, the friction plate is separated from the brake disc by the return of the piston, the sliding of a brake caliper and the centrifugal force when the brake disc rotates. But there is no fixed connection between the friction plate and the piston, and between the friction plate and the brake caliper. When the brake fluid pressure is released, the piston returns to the brake caliper cylinder hole under the action force of the deformation recovery of the rectangular ring, and the brake caliper slides in the opposite direction under the action of the reaction force, so that the effect of releasing the inner friction plate and the outer friction plate is achieved. However, the inner friction plate is not fixedly connected with the piston, the outer friction plate and the brake caliper, and the inner friction plate and the outer friction plate are difficult to completely and rapidly separate only by virtue of centrifugal force generated when the brake disc rotates, so that the dragging phenomenon can be generated, the service life of the friction plate is shortened, and the oil consumption or the electricity consumption of an automobile is greatly increased.

As a further technical scheme, the inner friction plate and the outer friction plate further comprise friction blocks, steel backs and silencing plates, wherein the friction blocks are fixed on one side of each steel back, the silencing plates are fixed on the other side of each steel back, and cold adhesive layers are arranged on the surfaces of the silencing plates; the friction blocks of the inner friction plate and the friction blocks of the outer friction plate are opposite to each other.
The beneficial effects of the utility model are as follows:
1. the structure is simple, industrialization is easy, cost increase is less, and the adopted cold adhesive is the same as the cold adhesive used on the inner side of the silencing sheet;
2. the effect of reducing the dragging torque is obvious through practical verification, and the dragging torque is reduced by about 15 percent;
3. the device has a certain noise reduction effect, and the complete and rapid separation of the discs shortens the duration of friction noise among the discs and reduces decibels; the flexible cold adhesive can reduce vibration noise among the piston, the brake caliper and the friction plate.

Detailed Description
The utility model will be described in detail below with reference to the attached drawings:
examples: as shown in figure 1, the novel structure for reducing drag torque comprises a piston 1, a rectangular ring 2, an inner friction plate 3, an outer friction plate 4 and a brake caliper 5, wherein the piston 1 is arranged in a cylinder hole of the brake caliper 5 in a sliding manner, and the rectangular ring 2 is sleeved on the periphery of the piston 1 and is limited by a clamping groove 7 arranged in the cylinder hole of the brake caliper 5; the inner friction plate 3 is fixed on the end face of one side of the piston 1 facing the brake caliper 5 through a cold adhesive layer 6; the outer friction plate 4 is fixed on the end face of the brake caliper 5, which faces the piston 1, through a cold adhesive layer 6; during braking, the piston 1 pushes the inner friction plate 3 to clamp the outer friction plate 4 and the brake caliper 5; when the brake is released, the piston 1 returns to the cylinder hole of the brake caliper 5 under the action force of the deformation recovery of the rectangular ring 2, the inner friction plate 3 is driven to return together, and meanwhile, the brake caliper 5 slides in the direction away from the piston 1 under the action of the reaction force, and the outer friction plate 4 is driven to slide together.
Referring to fig. 2, the inner friction plate 3 and the outer friction plate 4 further comprise friction blocks 8, a steel back 9 and a silencing plate 10, wherein the friction blocks 8 are fixed on one side of the steel back 9, the silencing plate 10 is fixed on the other side of the steel back 9, and a cold adhesive layer 6 is arranged on the surface of the silencing plate 10; the friction blocks 8 of the inner friction plate 3 and the friction blocks 8 of the outer friction plate 4 are opposite to each other.
The working process of the utility model comprises the following steps: during braking, hydraulic oil enters a cylinder hole of the brake caliper 5, hydraulic pressure pushes the piston 1 to slide along the inner wall of the cylinder hole, the rectangular ring 2 deforms along with the cylinder hole, and the piston 1 pushes the inner friction plate 3, so that the friction block 8 of the inner friction plate 3 clamps the friction block 8 of the outer friction plate 4 and the brake caliper 5, and braking is realized. After the brake fluid pressure is relieved, the piston 1 returns to the cylinder hole of the brake caliper 5 under the action force of the deformation recovery of the rectangular ring 2, and the inner friction plates 3 return together because the inner friction plates 3 are fixed on the piston 1; simultaneously, the brake caliper 5 slides in the opposite direction (namely, in the direction away from the piston 1) by the reaction force, and the outer friction plate 4 slides together because the outer friction plate 4 is fixed on the brake caliper 5, so that the inner friction plate and the outer friction plate are completely and quickly separated from the brake disc, and the dragging moment is reduced.
Through practical use tests, the drag torque of the brake caliper is reduced by about 15% compared with the prior art. In addition, the complete and rapid separation of the disks reduces the duration of friction noise between the disks and decibels; the flexible cold adhesive can reduce vibration noise among the piston, the brake caliper and the friction plate.
It should be understood that equivalents and modifications to the technical scheme and the inventive concept of the present utility model should fall within the scope of the claims appended hereto.
