Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a high-strength composite automotive brake disc. Background Technology

[0002] Traditional disc brakes work by clamping brake pads between calipers and brake discs, creating friction between the pads and discs to slow the vehicle down or stop. However, traditional disc brakes typically use cast iron discs. While cast iron discs are inexpensive, their one-piece molding limits the use of a single material, resulting in greater weight and poorer heat dissipation. Higher-end discs are made of carbon fiber, but this is more expensive and less readily available.

[0003] To address the aforementioned issues, Chinese Patent No. CN207005153U discloses an automotive brake disc and an automotive vehicle. By providing a first friction layer on the first brake disc surface of the brake disc portion, and a first adhesive layer between the first brake disc surface and the first friction layer, and by providing a second friction layer on the second brake disc surface of the brake disc portion, and a second adhesive layer between the second brake disc surface and the second friction layer, both the first and second friction layers are separated from the brake disc portion. This allows the brake disc portion, the first friction layer, and the second friction layer in the automotive brake disc to be manufactured using different materials.

[0004] While the aforementioned device can solve the problem in existing automotive brake discs where the entire disc can only be made of the same material due to its one-piece molding, in actual use, the two sides of the brake disc are respectively fixedly connected by adhesive to two sets of friction layers. When the car brakes, high temperatures and huge friction are generated during the braking process, which causes the adhesive properties at the bonding point to deteriorate, reducing the bonding strength between the friction layers and the brake disc, resulting in the friction layers falling off, affecting the braking effect, and even causing safety accidents. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength composite automotive brake disc to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a high-strength composite automotive brake disc, comprising a brake disc body, a first friction pad, a second friction pad, and multiple sets of composite docking mechanisms. The first friction pad and the second friction pad are respectively fixedly connected to the two side surfaces of the brake disc body through the multiple sets of composite docking mechanisms. Each composite docking mechanism includes a docking seat, a docking hole, an inner socket, and a fixing bolt. The docking seat is fixedly disposed on the surface of the first friction pad facing the brake disc body, and the inner socket is fixedly installed on the surface of the second friction pad facing the brake disc body. The docking hole is formed on the brake disc body, the docking seat is inserted into the docking hole, the inner socket is inserted into the docking seat, and the fixing bolt passes through the inner socket and is bolted to the docking seat.

[0007] Furthermore, in the aforementioned high-strength composite automotive brake disc, a first guide plate is provided on the outer periphery of the end of the mating seat fixed to the first friction plate, and an inner hole is provided inside the mating seat, with a screw hole at the bottom of the inner hole; a first mating groove is provided on the side of the mating hole near the mating seat, and a second mating groove is provided on the other side of the mating hole away from the mating seat; a second guide plate is provided on the outer periphery of the end of the inner socket fixed to the second friction plate, and an insertion hole is provided inside the inner socket, with a through hole communicating with the insertion hole on the second friction plate.

[0008] Furthermore, in the aforementioned high-strength composite automotive brake disc, the dimensions of the mating seat and the mating hole are matched, the dimensions of the inner hole and the inner socket are matched, the inner socket is inserted into the inner hole, the dimensions of the first guide plate and the first mating groove are matched, the first guide plate is inserted into the first mating groove, the dimensions of the second guide plate and the second mating groove are matched, the second guide plate is inserted into the second mating groove, and the fixing bolt passes through the through hole and the insertion hole in sequence and is screwed and fixed to the screw hole.

[0009] Furthermore, in the aforementioned high-strength composite automotive brake disc, both the first friction pad and the second friction pad are disc-shaped structures made of alloy cast iron.

[0010] Furthermore, in the aforementioned high-strength composite automotive brake disc, multiple sets of working grooves are uniformly formed on the surfaces of the first friction pad and the second friction pad.

[0011] Furthermore, in the aforementioned high-strength composite automotive brake disc, the working groove is arc-shaped.

[0012] Compared with the prior art, the high-strength composite automotive brake disc of this invention has the following advantages and beneficial effects:

[0013] (1) This utility model achieves a tight composite connection between the brake disc body, the first friction plate and the second friction plate through multiple sets of composite docking mechanisms including docking seats, docking holes, inner sockets and fixing bolts, ensuring that the first friction plate and the second friction plate will not be misaligned when subjected to force, thereby ensuring the stability of the brake disc body, the first friction plate and the second friction plate during operation, and improving the reliability and safety of the braking system.

[0014] (2) The composite docking mechanism of this utility model is hidden inside the brake disc, making the overall structure more compact. At the same time, not being exposed to the brake disc can also reduce the impact of external factors on the composite docking mechanism, such as the corrosion of dust and water vapor, which helps to extend the service life of the composite docking mechanism, thereby extending the service life of the car brake disc as a whole.

[0015] (3) The surfaces of the first friction pad and the second friction pad of this utility model are uniformly provided with multiple sets of arc-shaped working grooves, which can increase the contact area between the friction pad and the car brake pad, make the friction force distribution more uniform, thereby improving the braking effect and shortening the braking distance, thereby further improving the reliability and safety of the braking system.

[0016] (4) The present invention facilitates air circulation by setting up a working groove. During the braking process, the air can carry away the heat generated by friction through the working groove, reduce the temperature of the friction pads and the car brake pads, prevent the braking performance from deteriorating due to overheating, avoid the phenomenon of heat fade, and ensure the stability and reliability of the braking system. Moreover, the arc-shaped working groove can guide the flow of some debris and dust generated during the braking process, so that these debris and dust are discharged along the working groove, preventing them from accumulating on the friction pads, thereby reducing wear and extending the service life of the friction pads.

[0028] Preferably, the mating seat 41 has a cylindrical structure, and the dimensions of the mating seat 41 and the mating hole 42 are matched. The mating seat 41 is inserted into the mating hole 42. The dimensions of the inner hole 412 and the inner socket 43 are matched. The inner socket 43 is inserted into the inner hole 412.

The fixing bolt 44 passes through the through hole 432 and the insertion hole 431 in sequence and is screwed and fixed to the screw hole 413.

[0029] In a preferred embodiment, multiple sets of working grooves 21 are uniformly formed on the surfaces of the first friction plate 2 and the second friction plate 3, and the working grooves 21 are arc-shaped.

[0030] Preferably, both the first friction plate 2 and the second friction plate 3 are disc-shaped structures made of alloy cast iron.

[0031] The specific composite assembly process of the high-strength composite automotive brake disc of this utility model is as follows:

[0032] Multiple sets of mating seats 41 on the first friction plate 2 are inserted into the mating holes 42 opened on the brake disc body 1, and the first guide plate 411 is inserted into the first mating groove 421 to complete the mating installation between the first friction plate 2 and the brake disc body 1.

[0033] Insert the inner socket 43 on the second friction plate 3 into the inner hole 412, and insert the second guide plate 433 into the second docking groove 422 to complete the docking and installation work between the second friction plate 3 and the brake disc body 1.

[0034] The fixing bolt 44 passes through the through hole 432 and the insertion hole 431 in sequence and is screwed into the inside of the screw hole 413, thus completing the fixed installation work between the brake disc body 1, the first friction plate 2 and the second friction plate 3.

[0035] In the high-strength composite automotive brake disc of this utility model, a tight composite connection between the brake disc body 1, the first friction pad 2, and the second friction pad 3 is achieved through multiple sets of composite docking mechanisms 4, including docking seats 41, docking holes 42, inner sockets 43, and fixing bolts 44.

[0036] In the high-strength composite automotive brake disc of this utility model, the composite docking mechanism 4 is hidden inside the brake disc, making the overall structure more compact. At the same time, not being exposed to the brake disc can also reduce the impact of external factors on the composite docking mechanism 4, such as the corrosion of dust and moisture, which helps to extend the service life of the composite docking mechanism 4, thereby extending the overall service life of the automotive brake disc.

[0037] In the high-strength composite automotive brake disc of this utility model, multiple sets of arc-shaped working grooves 21 are uniformly opened on the surfaces of the first friction pad 2 and the second friction pad 3, which can increase the contact area between the friction pad and the automotive brake pad, make the friction force distribution more uniform, thereby improving the braking effect, shortening the braking distance, and further improving the reliability and safety of the braking system.

[0038] In the high-strength composite automotive brake disc of this utility model, the working groove 21 facilitates air circulation. During braking, air can carry away the heat generated by friction through the working groove 21, reducing the temperature of the friction pads and automotive brake pads, preventing a decrease in braking performance due to overheating, avoiding thermal fade, and ensuring the stability and reliability of the braking system. Moreover, the arc-shaped working groove 21 can guide the flow of debris and dust generated during braking, allowing these debris and dust to be discharged along the working groove 21, preventing them from accumulating on the friction pads, thereby reducing wear and extending the service life of the friction pads.
