Description

Technical Field

[0001] The utility model relates to the technical field of brake components, in particular to a brake disc component which is easy to adjust. Background Art

[0002] In recent years, people's quality of life has been getting better and better, and more and more cars have entered civilian families, which has driven people's consumption of cars, and the amount of cars has been on the rise. The continuous emergence of various new cars and the vigorous development of the automobile industry have accelerated the pace of progress of related mechanical industries, such as automobile-related parts: automobile brake discs, brake drums, etc. Brake discs play a role in braking and decelerating when the car is driving, so the sensitivity and life of the brake disc are of great importance. As the performance and driving speed of the vehicle are constantly improving, in order to increase the stability of the vehicle's braking when driving at high speeds, disc brakes have become the mainstream of the current brake system.

[0003] Most of the brake disc assemblies nowadays use the piston inside the brake caliper to push the friction block to perform friction braking on the brake disc to achieve the purpose of braking. However, there is only one set of pistons and friction blocks to brake the brake disc. When the friction block rubs against the brake disc for a long time, the friction position of the friction block and the brake disc will cause wear, which will affect the braking effect. The existing solution is to stop the car, send it for inspection, and replace the friction block or brake disc. This method is usually troublesome and inconvenient in some environments.

[0004] Therefore, it is urgent to design a brake disc assembly that can temporarily brake the vehicle when the original friction block and brake disc are severely worn, resulting in poor braking effect of the vehicle, without affecting the normal use of the vehicle. Utility Model Content

[0005] The purpose of the utility model is to provide a brake disc assembly that is easy to adjust, so as to achieve temporary adjustment to a new brake disc assembly for braking when the original brake disc assembly fails, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A brake disc assembly that is easy to adjust, comprising a brake disc and a brake caliper located at the outer end of one side thereof, a wheel hub being fixedly arranged in the middle position of the brake disc, an oil inlet being opened on one side of the brake caliper, the oil inlet being connected to a cavity located inside the brake caliper, a first piston and a second piston being respectively arranged inside the cavity and located above the left and right sides of the brake disc, and friction blocks being arranged on the front sides of the first piston and the second piston.

[0008] As a preferred solution of the utility model, the cavity is divided into two small cavities from top to bottom, and the first piston and the second piston are respectively distributed in the two cavities.

[0009] As a preferred solution of the utility model, a sealing assembly is provided between the upper and lower small cavities, and the sealing assembly respectively includes a sealing plate rotatably connected to the inner housing of the brake caliper through a hinge.

[0010] As a preferred solution of the utility model, a limiting groove is further provided on one side of the sealing plate away from the hinge, and a limiting sealing strip fixedly installed on the inner shell of the other side of the brake caliper is sealed and clamped inside the limiting groove.

[0011] As a preferred solution of the utility model, a side of the sealing plate close to the hinge is also connected to a driving member through a shaft, and the driving member is a micro-drive motor.

[0012] As a preferred solution of the utility model, the control end of the driving member is also electrically connected to a control circuit, and the driving member is electrically connected to a control panel in the vehicle cab via the control circuit.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, a brake disc assembly that is easy to adjust is provided. When the brake disc assembly is used, the original brake disc assembly (i.e., the first piston and the friction block located in the upper cavity) is firstly used for braking operation. After long-term use, when the original brake disc assembly or the brake disc is partially seriously worn, the sealing assembly is controlled to open, so that the brake fluid enters the cavity below, pushing the second piston and the friction block to move to the right and press onto the brake disc to achieve the purpose of braking, thereby achieving the adjustment of the brake assembly, so as not to affect the normal use of the vehicle, and the driver can also safely drive the vehicle to the maintenance place to replace the original brake disc assembly.

[0025] A brake disc assembly that is easy to adjust includes a brake disc 1 and a brake caliper 2 located at the outer end of one side of the brake disc 1. A wheel hub 3 is fixedly arranged at the middle position of the brake disc 1. An oil inlet 4 is opened on one side of the brake caliper 2. The oil inlet 4 is connected to a cavity 5 located inside the brake caliper 2. Brake fluid flows inside the cavity 5. A first piston 6 and a second piston 7 are respectively arranged inside the cavity 5 and above the left and right sides of the brake disc 1. Friction blocks 8 are arranged on the front sides of the first piston 6 and the second piston 7. The first piston 6 and the second piston 7 can push the friction blocks 8 to move so as to press onto the brake disc to perform braking action.

[0026] For details, please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The cavity 5 is divided into two small cavities from top to bottom, and the first piston 6 and the second piston 7 are respectively distributed in the two cavities; a sealing assembly 9 is arranged between the upper and lower small cavities, and the sealing assembly 9 respectively includes a sealing plate 91 which is rotatably connected to the inner shell of the brake caliper 2 through a hinge 92; a limiting groove 93 is also provided on the side of the sealing plate 91 away from the hinge 92, and a limiting sealing strip 94 fixedly installed on the inner shell of the other side of the brake caliper 2 is sealed and engaged inside the limiting groove 93, so as to improve the sealing when isolating the two cavities and prevent the brake fluid in the upper cavity from entering the cavity of the lower cavity; a driving member 95 is also connected to the side of the sealing plate 91 close to the hinge 92 through a shaft, and the driving member 95 adopts a micro driving motor;

[0027] In this embodiment, when the original brake disc assembly or the brake disc is severely worn locally, the driving member 95 in the sealing assembly 9 is controlled to work, and the driving member 95 drives the sealing plate 91 to rotate to connect the upper cavity and the lower cavity, so that the brake fluid enters the lower cavity, pushes the second piston 7 and the friction block 8 to move to the right, and presses onto the brake disc 1 to achieve the purpose of braking. Through the above operation, the original brake assembly can be adjusted to the new brake assembly for use, which will not affect the normal use of the vehicle and improves safety.
