The utility model discloses profitable effect is: the utility model discloses the structure has realized the function of friction disc initiative return through increasing the rubber spare to reduced the dragging moment of stopper, reduced the oil consumption of car, compared other designs, the utility model discloses a friction disc does not have extra return spring structure, in the aspect of the installation, easily maintains, through rubber spare and support interference contact, has solved friction disc noise problem.
Description
Technical Field
The utility model relates to a structure of friction disc, especially a noise reduction of friction disc and initiative return structure.
Background
The back plate of the existing friction plate is made of steel and is in rigid contact with the support, so that the back plate is easy to collide with the support to generate noise in the driving process of an automobile and does not have the function of active return. The friction plate does not have the function of active return after the automobile is braked, and needs to be thrown away by the aid of centrifugal force of a brake disc, so that dragging torque of the product is large, and oil consumption of the automobile is increased.
Disclosure of Invention
The utility model discloses solve above-mentioned prior art's shortcoming, provide a friction disc that simple structure, practicality are stronger and fall and initiative return structure.
The utility model provides a technical scheme that its technical problem adopted: the noise reduction and active return structure of the friction plate mainly comprises a support and the friction plate, wherein convex blocks at two ends of the back of the friction plate are embedded into grooves in corresponding positions of the support, a rubber piece is arranged on each convex block, each convex block is in contact with the corresponding groove through the corresponding rubber piece, the rubber piece is in interference fit with the corresponding groove of the support, and the friction plate is in contact with a brake disc through the pushing of a piston.
Bosses are arranged on the lower portions of the convex blocks at the two ends of the back of the friction plate.
The utility model discloses profitable effect is: the utility model discloses the structure has realized the function of friction disc initiative return through increasing the rubber spare to reduced the dragging moment of stopper, reduced the oil consumption of car, compared other designs, the utility model discloses a friction disc does not have extra return spring structure, in the aspect of the installation, easily maintains, through rubber spare and support interference contact, has solved friction disc noise problem.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the structure of the automobile during braking;
FIG. 3 is a schematic diagram of the structure of the automobile after the brake is released.
Description of reference numerals: the brake comprises a support 1, a friction plate 2, a rubber part 3, a brake disc 4 and a boss 5.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in the figure, this kind of friction disc is fallen and initiatively return structure, mainly include support 1 and friction disc 2, in the lug embedding support 1 relevant position's at 2 back both ends of friction disc the recess, be equipped with rubber spare 3 on the lug, the lug passes through rubber spare 3 and groove contact to solve the problem that the inter-metal collision produced the noise of traveling in-process, rubber spare 3 is interference fit with the recess of support 1, friction disc 2 contacts through piston promotion and brake disc 4. The bosses 5 are arranged on the lower portions of the lugs at the two ends of the back of the friction plate 2, and the bosses 5 at the two ends of the back of the friction plate 2 are stressed during braking, so that the problem that the rubber part 3 is damaged or falls off when bearing excessive load is solved.
During the braking process of the automobile: the piston pushes the friction plate 2 to move towards the direction of the brake disc 4, and the rubber piece 3 on the friction plate 2 is in interference fit with the support 1, so that the friction plate 2 moves, but the movement amount of the rubber piece 3 is smaller than or not movable than that of the friction plate 2, and the rubber piece 3 deforms.
After the automobile brake is released: after the automobile is braked and released, the piston is actively returned by the rectangular sealing ring, the force applied on the friction plate 2 by the piston is relieved, and at the moment, the rubber piece 3 returns to a normal state from a deformation state, so that the friction plate 2 is driven to return, the friction plate 2 is separated from the brake disc 4 by the force pulled back by the rubber piece 3, the problem that the friction plate 2 rubs the disc is solved, and the dragging torque of the brake is reduced.
In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
