Technical Field

The invention relates to the field of brakes, in particular to a light air pressure disc brake.

Background

With the rapid development of logistics, heavy vehicles are more and more, a brake is an indispensable part of the heavy vehicles, a disc brake is gradually replacing a drum brake, and the light weight of the disc brake plays an important role in reducing the weight of the automobile, saving energy, reducing emission and improving efficiency. The conventional disc brake is large in size and weight, and brings great inconvenience to the total mass of an automobile, the energy-saving and emission-reducing effects and later maintenance. The invention mainly solves the defects in the prior art and provides a light-weight disc brake.

Disclosure of Invention

The invention aims to solve the problems in the prior art, and designs a novel clamp body bracket for reducing the weight of a brake, which has the advantages of smaller mass, simpler and more convenient installation, lower manufacturing cost and higher production efficiency.

In order to achieve the purpose, the invention provides the following technical scheme: the brake caliper comprises a brake disc, a brake caliper body, a caliper body bracket and a friction lining; the brake caliper body is internally provided with a pressure arm which generates thrust under the action of an external air chamber, a support seat assembly pushes a friction lining friction brake disc to brake, and a master-slave adjusting mechanism adjusts the brake clearance.

Preferably, a sealing device is arranged outside the brake caliper body.

Preferably, a sealing device is arranged outside the brake caliper body.

Compared with the prior art, the invention has the beneficial effects that: the plate-shaped bracket adopted by the invention can greatly reduce the weight of the brake, reduce the size of the bracket, reduce the use of raw materials required by casting, greatly save the production cost, reduce the weight of the whole vehicle and improve the energy conservation and emission reduction. The heat dissipation performance of the friction lining on the other side for hanging installation is relatively improved because the bracket is only arranged on one side.

The brake caliper comprises a caliper body 1, a first brake lining 2a, a second brake lining 2b, a pressure arm 3, a self-adjusting mechanism 4, a caliper body bracket 5, a brake disc 6, a threaded pipe 7 and a support seat assembly 8.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b): the invention provides a technical scheme that: as shown in fig. 1-a, comprises a brake disc 6, a caliper body 1, a caliper body bracket 5, a first brake lining 2a and a second brake lining 2 b; a pressure arm 3 is arranged in the brake caliper body 1 and generates thrust under the action of an external air chamber, a support seat assembly 8 pushes a brake lining friction brake disc 6 to brake, and a master-slave adjusting mechanism adjusts a brake clearance; the outside is provided with a sealing device which can ensure that the air tightness in the clamp body 1 is good.

The bracket adopts a plate-shaped bracket which is different from the traditional bracket, and compared with the traditional bracket, the weight of the bracket is reduced by more than half. One friction lining is arranged on the bracket and the other friction lining is hung in a groove at the outer side of the caliper body. This design is more light than traditional disc brake, and the structure is more simple, and heat dispersion improves relatively.

The caliper bracket 5 is fixedly arranged on the axle, when pressure is input by air pressure, the air chamber can push the pressure arm 3 in the brake caliper 1 to further push the supporting seat assembly 8 to enable the brake lining 2b to move leftwards to eliminate the clearance between the brake lining and the brake disc 6, and the pressure is transmitted to the brake lining 2 b. When the brake lining 2b contacts the brake disc 6, the axial movement of the brake disc 6 is restricted, so that the brake disc 6 is acted on the caliper body 1 by a reaction force, the caliper body is applied with a reverse force to slide rightwards, the brake lining 2a is moved rightwards to clamp the brake disc 6, and a friction force is generated to act on the brake disc 6 to make the brake disc 6 static.

The main adjusting fork is in spline connection with a threaded pipe 7 on a supporting seat assembly 8, and the supporting seat assembly 8 is in threaded connection with the threaded pipe 7. When the friction lining is worn, the clearance is enlarged, and the pushing stroke of the pressure arm and the supporting seat is enlarged. When the stroke of the pressure arm reaches a preset value, the shifting fork on the pressure arm shifts the main adjusting fork on the self-adjusting mechanism 4 to rotate, so that the threaded pipe 7 is driven to rotate, the threads of the threaded pipe 7 rotate to push the supporting seat assembly 8 to move, and the gap between the friction lining and the brake disc is ensured within a preset range.
