Description

Technical Field

[0001] The utility model relates to the technical field of braking components, in particular to a high-strength iron-aluminum brake drum. Background Art

[0002] A brake is a component in a braking system that generates a braking force to impede the movement or movement tendency of a vehicle. Except for various retarders, almost all automotive brakes are friction brakes that generate braking torque by the friction between the working surfaces of fixed elements and rotating elements. A brake drum is a friction pair of a drum brake. In addition to having the strength and stiffness required as a component, it should also have as high and stable a friction coefficient as possible, as well as appropriate wear resistance, heat resistance, heat dissipation, and heat capacity. However, when the existing brake drum works frequently, the local temperature of the brake drum will be higher, making the brake drum in a severe thermal fatigue state and difficult to meet people's requirements for the safety, durability, and smoothness of automobiles; in addition, the structural reinforcement firmness and ventilation and heat dissipation performance of the existing brake drum are not good, affecting the braking effect.

[0003] In order to solve the deficiencies of the existing technology, people have carried out long-term explorations and proposed various solutions. For example, a Chinese patent document discloses an aluminum-iron composite brake drum [CN201621379385.8], which includes a layer of aluminum alloy heat dissipation structure layer compounded on the outer circumferential surface of the brake drum body. There is a compound interface between the aluminum alloy heat dissipation structure layer and the brake drum body, and the aluminum alloy heat dissipation structure layer and the brake drum body are of the same body. The brake drum body is made of cast iron, and the aluminum alloy heat dissipation structure layer is made of high-strength aluminum alloy material.

[0004] The above solution solves to a certain extent the problem that the brake drum in the existing technology is difficult to meet people's requirements for the safety, durability, and smoothness of automobiles, but this solution still has many deficiencies, such as: the structural reinforcement firmness and ventilation and heat dissipation performance are not good, affecting the braking effect.

The heat dissipation diversion structures 5 are connected to the plug-in seat connection structure 3.

[0025] Among them, the plug-in separation structure 2 includes a plug-in connecting rod 21 provided on the circumferential direction of one end of the brake drum body 1, an annular end cover 22 is provided at the end of the plug-in connecting rod 21 away from the brake drum body 1, and a diversion gap 23 is formed between two adjacent plug-in connecting rods 21.

[0026] Visibly, the plug-in connecting rod 21 is a movable telescopic structure, and a locking screw 24 for fixing the end of the plug-in connecting rod 21 is provided on the annular end cover 22.

[0027] The size of the diversion gap 23 can be adjusted according to requirements, and the heat flow generated when the brake drum is heated is subjected to air-cooled heat exchange through the diversion gap 23.

[0028] Obviously, the plug-in seat connection structure 3 includes a plurality of annular plug-in connection seats 31 provided on the outer circumferential wall of the brake drum body 1. There is a positioning gap 32 between the annular plug-in connection seats 31, and an annular aluminum heat-conducting seat 33 fixedly connected to the outer wall of the brake drum body 1 is provided in the positioning gap 32.

[0029] Furthermore, connection slots 34 are provided on both sides of the annular plug-in connection seat 31, connection blocks 35 corresponding to the connection slots 34 are provided on both sides of the annular aluminum heat-conducting seat 33, and the connection blocks 35 are inserted into the connection slots 34.

[0030] The outer circumferential wall of the brake drum body 1 is connected by an annular plug-in structure, and heat transfer is performed on its outer wall.

[0031] Even further, the heat dissipation diversion structure 5 includes a heat-conducting ring body 51 disposed between the structure strengthening ring body 4 and the annular plug-in connection seat 31 and inclined. The heat-conducting ring body 51 is connected end to end, and its inner wall is connected to the annular plug-in connection seat 31 and the other wall is connected to the inner wall of the structure strengthening ring body 4.

[0032] A heat dissipation air cavity is formed between the heat-conducting ring bodies 51, and an opening is provided at one end away from the annular end cover 22. Air flow holes are provided on the heat-conducting ring body 51 here.

[0033] Specifically, the inner wall of the structure strengthening ring body 4 has a heat-conducting aluminum layer 41, and a thickened steel structure layer 42 covers the outer circumferential wall of the heat-conducting aluminum layer 41.

[0034] Such a setting enhances the structural strength during the process of ensuring heat dissipation.

[0035] Preferably, a heat-conducting tube body 52 is inserted into the structure strengthening ring body 4. One end of the heat-conducting tube body 52 penetrates into the heat-conducting aluminum layer 41 and the other end penetrates into an annular heat dissipation block 53 on the outer wall of the thickened steel structure layer 42.

Secondly, internal heat exchange is carried out by using the diversion gap 23, and the heat dissipation cavity 55 is dissipated by using the heat-conducting channel 54, so as to improve the heat dissipation effect. At the same time, the heat dissipation intensity is improved and the structure is enhanced by the combination of iron and aluminum.
