Description

Technical Field

[0001] The invention belongs to the technical field of automobiles, and in particular relates to an automobile braking system. Background Art

[0002] Disc brakes are now widely used in passenger cars. Most cars now use them on all wheels, while a few only use them on the front wheels, working in conjunction with drum brakes on the rear wheels to provide greater directional stability during braking. In commercial vehicles, disc brakes are increasingly being adopted in new and high-end models. The automotive brake disc is a crucial component of the vehicle's braking system, ensuring braking. It is typically made of cast iron, steel, or carbon fiber composites, offering high strength and wear resistance. The brake disc is mounted on the wheel and works in conjunction with the brake pads. When the driver depresses the brake pedal, brake fluid is transferred through the braking system to the brake pads attached to the disc. The friction between the pads and disc slows or stops the wheel.

[0003] In the process of using a car, stepping on the brakes is a necessary step, especially in urban roads with many traffic lights and intersections. Frequent stepping on the brakes causes the brake discs to rub more frequently, which will cause the following deficiencies: 1. In the prior art, the brake pads on the inner side of the brake caliper first contact and brake with the adjacent brake disc under the action of the oil pump, and then the brake pads outside the brake caliper contact and brake with the adjacent brake disc, which makes the brake disc on the inner side wear more than the brake disc on the outer side. Therefore, when the inner brake disc does not meet the use conditions, the entire brake disc needs to be replaced in time, which greatly reduces the service life of the brake disc; 2. Since the brake pads do not cover the outer edge of the brake disc, After long-term wear of the brake disc and brake pad, a circle of annular protrusions will appear on the outer edge of the brake disc. When the vehicle shakes, the outer edge of the brake pad will contact the annular protrusion formed on the brake disc, thereby generating a large noise. Although it does not affect the use of the car, the noise caused by occasional braking makes the driving experience worse; 3. With the long-term use of the brake disc, a large amount of heat will be generated. Although there is a solution of setting through holes to solve the heat dissipation problem in the existing technology, the heat dissipation effect is poor; 4. When the brake disc and brake pad are in use, a lot of dust and debris will be generated. When the dust and debris stick between the brake disc and the brake pad, it will cause uneven friction and noise, thereby affecting the service life of the brake disc. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an automobile braking system.

[0005] The technical solution is as follows: a vehicle braking system, comprising a brake caliper (5), a first brake pad (7) being installed on the outside of the brake caliper (5), a second brake pad (8) being installed on the inside of the brake caliper (5) via an oil pump (3), a first brake disc (1) and a second brake disc (2) being installed between the first brake pad (7) and the second brake pad (8), the first brake disc (1) being close to the first brake pad (7), the second brake disc (2) being close to the second brake pad (8), and a brake drum (3) being installed on the disc surface of the first brake disc (1), the key point being that the thickness of the second brake disc (2) is greater than that of the first brake disc (1);

[0006] A connecting strip (4) is evenly distributed between the first brake disc (1) and the second brake disc (2), and the connecting strip (4) is an arc-shaped structure. When the first brake disc (1) and the second brake disc (2) rotate clockwise, the end of the connecting strip (4) close to the center of the second brake disc (2) is the front end, and the end close to the edge of the second brake disc (2) is the rear end;

[0007] With the above structure, the thickness of the second brake disc is designed to be greater than that of the first brake disc according to the degree of wear, which greatly extends the service life of the entire brake disc. At the same time, the connecting strip is designed into an arc structure, which gives it a good air-guiding structure and improves the heat dissipation effect.

[0008] Preferably, a circumferential avoidance step (a) is provided on the edges of the first brake disc (1) and the second brake disc (2) that are away from each other.

[0009] With the above structure, when the brake disc and brake pad are used together, the brake pad can cover the outer edge of the brake disc without generating annular bulges, thereby avoiding abnormal sounds or noises when the car brakes, and improving driving safety and comfort.

[0010] Preferably, the thickness of the avoidance step (a) is L, and 2mm≤L≤4mm. This does not affect safety and also prevents the brake disc from making noise before it is scrapped.

[0011] Preferably, L=3 mm.

[0012] Preferably, a first guide groove (11) is evenly provided on the outer disc surface of the first brake disc (1), and the first guide groove (11) is an inclined groove from shallow to deep from the edge to the center of the first brake disc (1), and the bottom of the first guide groove (11) near the center of the first brake disc (1) passes through the inner disc surface of the first brake disc (1);

[0013] Second guide grooves (21) are evenly formed on the outer disc surface of the second brake disc (2), and the second guide grooves (21) are inclined grooves from shallow to deep from the edge to the center of the second brake disc (2), and the bottom of the second guide groove (21) near the center of the second brake disc (2) passes through the inner disc surface of the second brake disc (2);

[0014] Three air blowing pipes (6) are installed on the brake caliper (5), and the three air blowing pipes (6) are distributed to blow toward the first guide groove (11), between the first brake disc (1) and the second brake disc (2), and the second guide groove (21).

[0015] With the above structure, the first guide groove (11) and the second guide groove (21) have the function of guiding the wind and discharging the dust and debris. Since the first guide groove (11) and the second guide groove (21) are inclined grooves from shallow to deep from the edge to the center, they have good wind guiding performance and thus have a good heat dissipation effect. At the same time, this structure is also conducive to the discharge of dust and debris from the inside of the brake disc, without affecting the use of the brake disc. Based on the above structure, three air blowing pipes are provided, and the wind from the air blowing pipes blows directly to the first guide groove, between the first brake disc and the second brake disc, and the second guide groove, so that the heat dissipation and dust removal effects are better.

[0016] Preferably, the outlet of the first guide groove (11) penetrating the inner surface of the first brake disc (1) and the outlet of the second guide groove (21) penetrating the inner surface of the second brake disc (2) are arranged opposite each other;

[0017] The outlet of the first guide groove (11) penetrating the inner surface of the first brake disc (1) and the outlet of the second guide groove (21) penetrating the inner surface of the second brake disc (2) are located between adjacent connecting bars (4). This structure has better heat dissipation and dust removal effects.

[0018] Preferably, when the first brake disc (1) and the second brake disc (2) rotate clockwise, the end of the first guide groove (11) close to the center of the first brake disc (1) is the front end, and the end close to the edge of the first brake disc (1) is the rear end;

[0019] The end of the second guide groove (21) close to the center of the second brake disc (2) is the front end, and the end close to the edge of the second brake disc (2) is the rear end. With the above structure, when the car is running, the wind from the front side flows into the first guide groove and the second guide groove to a greater extent, and the heat dissipation and dust removal effects are better.

[0020] Preferably, the opening edges of the first guide groove (11) and the second guide groove (21) are both rounded.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the thickness of the second brake disc is designed to be greater than that of the first brake disc according to the degree of wear, which greatly extends the service life of the entire brake disc. At the same time, the connecting strip is designed to be an arc-shaped structure, so that it has a good air-guiding structure and improves the heat dissipation effect; it also solves the problem of annular bulges and abnormal sounds or noises after long-term use of the brake disc, and at the same time improves the heat dissipation and dust removal effects of the brake disc, increases the service life of the brake disc, and thus improves the safety and comfort of vehicle driving.
