Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an ABS gear ring brake disc. Background Technology

[0002] like Figure 1 As shown, in traditional vehicle axle braking systems, the brake disc and ABS gear ring are usually connected by bolts. Under the high-temperature environment of frequent braking, due to the difference in thermal expansion coefficients between the brake disc and the ABS gear ring, as well as vibration, the connecting bolts are prone to loosening or even falling off.

[0003] like Figure 2 As shown, the ABS gear ring is integrated with the brake disc. In this case, the ABS gear ring is too close to the brake disc, and the ABS sensor is prone to high temperature erosion, which can cause the ABS signal to fail and seriously affect driving safety.

[0004] In summary, existing technologies employ auxiliary methods such as anti-loosening nuts and thread-locking adhesives, but these cannot completely solve the loosening problem at high temperatures and increase assembly complexity and maintenance costs. While some designs integrate the ABS gear ring and brake disc, the gear ring is inserted too deeply into the brake disc cavity or too close to the friction surface, leading to high-temperature ablation of the ABS sensor.

[0005] Therefore, the main drawbacks of the existing technology are: the existing ABS gear ring mounting structure has many parts, complex assembly, and a high failure rate of ABS sensors, which affects driving safety. Utility Model Content

[0006] The technical problems to be solved by this utility model are: firstly, how to solve the problem of the traditional ABS gear ring mounting bolts loosening at high temperatures; secondly, how to solve the problem of complex assembly and high maintenance cost of ABS gear rings. Therefore, an integrated ABS gear ring brake disc is provided.

[0007] To solve the above problems, this utility model is achieved through the following technical solution:

[0008] An ABS gear ring integrated brake disc includes a brake disc with a cavity in the center of the brake disc, and the ABS gear ring is located in the cavity.

[0009] The brake disc includes an inner first friction surface and an outer second friction surface;

[0010] The ABS gear ring includes several gear ring bases, each gear ring base is provided with teeth, the gear ring base of the ABS gear ring is connected to the first friction surface, the teeth of the ABS gear ring are higher than the second friction surface; and an ABS sensor is provided above the ABS gear ring.

[0011] In the brake disc, there are heat dissipation ribs between the first friction surface and the second friction surface, and a first ventilation groove is formed between adjacent heat dissipation ribs; in the ABS gear ring, a second ventilation groove is formed between adjacent gear ring bases, and the first ventilation groove and the second ventilation groove are connected.

[0012] The gear ring base is connected to the first friction surface of the brake disc as a single unit.

[0013] There is a gap between the ABS gear ring and the inner side of the second friction surface in the brake disc.

[0014] Weight reduction holes are provided in the teeth and / or base of the ABS gear ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Completely eliminate the risk of bolted connection failure and improve reliability under high-temperature conditions;

[0017] 2. Reduce the number of parts and lower assembly costs;

[0018] 3. By casting an integral structure, the overall rigidity is improved, and signal interference caused by vibration is reduced;

[0019] 4. Increase the distance between the ABS gear ring and the brake disc friction surface to avoid high-temperature erosion of the ABS sensor. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the ABS gear ring integrated brake disc includes a brake disc 1, with a cavity in the center of the brake disc 1, and the ABS gear ring 2 located in the cavity.

[0029] The brake disc 1 includes an inner first friction surface 11 and an outer second friction surface 12;

[0030] The ABS gear ring 2 includes several gear ring bases 23, each with teeth 21. The gear ring bases 23 of the ABS gear ring 2 are connected to the first friction surface 11, and the teeth 21 of the ABS gear ring 2 are higher than the second friction surface 12. An ABS sensor 3 is positioned above the ABS gear ring 2. This arrangement, with the teeth 21 higher than the second friction surface 12, ensures that the ABS sensor 3, located above the teeth 21, is at a certain distance from the second friction surface 12, preventing the ABS sensor 3 from failing due to high temperatures.

[0031] Furthermore, such as Figure 5 , Figure 6 As shown, in the brake disc 1, there is a heat dissipation rib 14 between the first friction surface 11 and the second friction surface 12, and a first ventilation groove 13 is formed between adjacent heat dissipation ribs 14; in the ABS gear ring 2, a second ventilation groove 22 is formed between adjacent gear ring bases 23, and the first ventilation groove 13 and the second ventilation groove 22 are connected.

[0032] Furthermore, the gear ring base 23 is connected to the first friction surface 11 of the brake disc 1 as a whole, so that the ABS gear ring 2 and the brake disc 1 can be integrally cast or integrally machined.

[0033] Furthermore, a gap is left between the ABS toothed ring 2 and the inner side 15 of the second friction surface in the brake disc 1, so that the ABS toothed ring 2 is located outside the brake disc cavity. In this way, the ABS sensor 3 is at a certain safe distance from both the second friction surface 12 and the inner side 15 of the second friction surface, so as to avoid the ABS sensor 3 being burned by high temperature radiation from the brake disc.

[0034] Furthermore, weight reduction holes are provided in the tooth portion 21 and / or the tooth base 23 of the ABS toothed ring 2.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
