Description

Technical Field

[0001] The invention relates to an automobile component, in particular to an automobile brake bracket device. Background Art

[0002] The traditional automobile brake bracket device achieves braking by separating and expanding the two brake shoes fixed on the brake bracket to fit tightly against the brake hub. Since the traditional brake shoes are two horseshoe-shaped entities, after stepping on the brake, the two horseshoe-shaped brake shoes will expand outward and fit tightly against the brake hub. However, since they are two horseshoe-shaped entities, the outward expansion will make it difficult for the two ends of the brake shoes to fit tightly against the brake hub, resulting in poor braking effect and directly affecting the safety performance of the car. Summary of the invention

[0003] The purpose of the present invention is to solve the above-mentioned practical problems and provide a car brake bracket device, which can make the outer circumferences of two horseshoe-shaped brake shoes fit tightly with the brake hub from both ends to the middle to achieve braking, which is beneficial to improving the braking safety performance of the car.

[0004] The present invention includes a bracket body for automobile brakes, and the technical solution adopted is: the bracket body with a sleeve shaft is closely attached to the outer periphery of two horseshoe-shaped brake shoes that are relatively arranged and are broken into two halves in the middle, the horseshoe-shaped brake shoes divided into two halves are connected to form an integral brake shoe through a hinge-type connecting shaft on the outside of the breaking line, and the horseshoe-shaped brake shoes divided into two halves are elastically pulled together by a tension spring plate on the inside of the breaking line for use, the tension spring plate is sleeved on the middle of the central axis on both sides of the horseshoe-shaped brake shoe, and the rear ends of the two ends are bent inwardly and fixed on the tension adjustment fixing cards on both sides of the brake shoe, and the integral horseshoe-shaped brake shoe thus formed is movably riveted to the bracket body through a connecting block, and a convex return trapezoidal pile is provided on the bracket body at the intersection of the side ends of the two horseshoe-shaped brake shoes, and a return spring sheet is installed between the return trapezoidal pile and the two horseshoe-shaped brake shoes through a convex point, and a friction buffer wheel is provided between the side ends of the two horseshoe-shaped brake shoes and the inclination of the return trapezoidal pile.

[0005] In the above technical solution: a brake expansion wheel is arranged between the intersection of the other side of the horseshoe-shaped brake shoe and the other side of the horseshoe-shaped brake shoe.

[0006] Compared with the prior art, the present invention has the following advantages and effects: due to the adoption of the above technical scheme, by setting the two horseshoe-shaped brake shoes as a combination disconnected from the middle, when used after installation, the two horseshoe-shaped brake shoes move to the right with the return trapezoidal pile to perform work, and then the two horseshoe-shaped brake shoes form an outward expansion effect from the disconnection in the middle, thereby increasing the area where the brake pads on the outer periphery of the horseshoe-shaped brake shoes and the brake hub are in close contact, so that the brake pads on the brake shoes can produce friction braking with the brake hub from both ends to the middle, solving the problem that the two ends of the traditional brake shoes cannot be closely attached to the brake hub, which is unfavorable to safety, and is beneficial to increasing the braking area and improving the safety performance of automobile braking.

DETAILED DESCRIPTION

[0011] Figure 1 , Figure 2 As shown: a bracket body 1 with a sleeve shaft is close to two horseshoe-shaped brake shoes 2 arranged opposite to each other on the outer periphery and is broken into two halves in the middle. The horseshoe-shaped brake shoes 2 divided into two halves are connected as an integral brake shoe by a hinged connecting shaft 4 on the outside of the breaking line 3. The horseshoe-shaped brake shoes 2 divided into two halves are elastically pulled together by a tension spring plate 5 on the inside of the breaking line 3 for use. The tension spring plate 5 is sleeved on the middle of the central axis 7 on both sides of the horseshoe-shaped brake shoe 2, and the rear ends are bent inward and fixed on the tension adjustment fixing cards 6 on both sides of the brake shoe. The integral horseshoe-shaped brake shoe 2 thus formed is movably riveted to the bracket body 1 through a connecting block 8. A convex return trapezoidal pile 9 is provided on the bracket body 1 at the intersection of the side ends of the two horseshoe-shaped brake shoes 2, and a return spring sheet 11 is installed between the return trapezoidal pile 9 and the two horseshoe-shaped brake shoes 2 through a convex point 12, and a friction buffer wheel 10 is provided between the side ends of the two horseshoe-shaped brake shoes 2 and the inclination of the return trapezoidal pile 9. A brake expansion wheel 13 is provided between the intersection of the other side of the horseshoe-shaped brake shoe 2 and the other side.

[0012] In the present technical scheme, the brake expansion wheel 13 is a component attached to the original bracket body 1. After the foot brake is applied, the brake expansion wheel 13 immediately rotates 90° to horizontally open one end of the horseshoe brake shoe 2 that is in close contact with the brake wheel hub, so that the horseshoe brake shoe 2 expands toward the periphery of the bracket body 1 and is in close contact with the brake wheel hub for braking. Since the horseshoe brake shoe 2 is movably riveted to the bracket body 1 using a connecting block 8, the other end of the horseshoe brake shoe 2 can be twisted. At the same time, the middle breaking line 3 extends outward with the hinged connecting shaft 4 so that the horseshoe brake shoe 2 is in close contact with the brake wheel hub as a whole. The hinged connecting shaft 8 is oriented to allow the horseshoe brake shoe 2 to twist, and the inclined end of the tail end also moves to the right with the twisting. Since the friction buffer wheel 10 is in close contact with the inclined surface of the return trapezoidal pile 9, the horseshoe brake shoe 2 can be slightly moved to the right to achieve the braking effect at the tail end. After the brake pedal is released, the return spring 11, under the elastic action of the convex point 12, allows the horseshoe-shaped brake shoe 2 to rebound as a whole, and the tension spring plate 5 then rebounds to return the two halves of the horseshoe-shaped brake shoe 2 to their original state, thereby achieving the technical purpose.

[0013] According to the original technology, the connecting block 8 is provided with a convex shaft on the bracket body 1, and after the connecting block 8 is installed and connected, it is fixed with a pin. The present technical solution adopts an active riveting method, which can also be implemented according to the original technology, that is, a convex shaft is provided on the bracket body 1, and after the connecting block 8 is installed, it is fixed with a pin.
