Description

Technical Field

[0001] The present application relates to the technical field of automobile brake pads, and in particular to a brake pad steel back with a threaded copper column. Background Art

[0002] At present, the steel back of the brake pad needs to be shot blasted (to increase surface roughness) and coated with glue (to increase adhesion) to enhance the bonding strength between the friction material and the steel back and improve driving safety.

[0003] However, commercial vehicles with heavy weight and load as well as racing cars require higher shear strength of the brake pad steel back. The brake pad steel back still has safety hazards after ordinary treatment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present application provides a brake pad steel back with a threaded copper column, which is fixedly connected by the threaded copper column. The threaded structure of the copper column is conducive to increasing the contact area and strength between the copper column and the friction material. After the hot pressing process, the friction material is tightly bonded to the steel back, thereby improving the shear strength of the brake pad.

[0005] The technical solution of this application to solve the above technical problems is as follows:

[0006] A brake pad steel back with a threaded copper column comprises a steel back body, a threaded hole is opened on the steel back body, a threaded copper column is arranged on the steel back body, and one end of the threaded copper column is threadedly connected to the threaded hole.

[0007] Furthermore, the threaded copper column includes a coarse screw portion, a coarse connecting portion and a thin screw portion, and the coarse screw portion is threadedly connected to the threaded hole.

[0008] Furthermore, a cutout is provided on a side of the thick connecting portion.

[0009] Furthermore, the steel back body is connected to a friction lining via a thick connecting portion and a thin screw portion.

[0010] Furthermore, the diameters of the coarse screw portion and the coarse connecting portion are the same.

[0011] Furthermore, the height of the thick screw portion is less than or equal to the thickness of the steel back body.

[0012] Furthermore, the sum of the heights of the thick connecting portion and the thin screw portion is less than or equal to the thickness of the friction lining.

[0013] Furthermore, the coarse screw portion, the coarse connecting portion and the fine screw portion are integrally formed.

[0014] Furthermore, the number of the threaded holes is multiple and evenly distributed, with one threaded hole per 6 to 7 cm on the steel back body. 2 A threaded hole is provided.

[0015] In summary, compared with the prior art, the above technical solution has the following beneficial effects:

[0016] The present application describes a brake pad steel back with a threaded copper cylinder, in which the steel back body and the friction lining are stably connected via the threaded copper cylinder. By increasing the contact area and strength between the threaded copper cylinder and the steel back body and the friction lining, the friction lining is tightly bonded to the steel back body after a hot pressing process, which is beneficial to improving the shear strength of the brake pad.

[0022] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0023] The embodiment of the present application discloses a brake pad steel back with a threaded copper column.

[0024] Reference Figure 1-Figure 4 A brake pad steel back with a threaded copper column comprises a steel back body 1, a threaded hole 2 is opened on the steel back body 1, a threaded copper column is arranged on one side of the steel back body 1, one end of the threaded copper column is threadedly connected to the threaded hole 2, a friction lining 9 is arranged on one side of the steel back body 1 through a hot pressing process, the friction lining 9 is fixedly connected to the threaded copper column, and the friction lining 9 is connected to the steel back body 1 through the threaded copper column.

[0025] A groove 8 is provided on one side of the friction lining 9, and the threaded holes 2 are arranged to avoid the groove 8. The number of the threaded holes 2 is multiple and evenly distributed, and the steel back body 1 has a groove 8 every 6 to 7 cm. 2A threaded hole 2 is provided. The steel back body 1 and the friction lining 9 are stably connected through the threaded copper column. By increasing the contact area and strength between the threaded copper column and the steel back body 1 and the friction lining 9, the friction lining 9 is tightly bonded to the steel back body 1 after the hot pressing process, which is beneficial to improving the shear strength of the brake pad.

[0026] The threaded copper column includes a coarse screw portion 4, a coarse connecting portion 5 and a fine screw portion 6, wherein the coarse screw portion 4 is threadedly connected to the threaded hole 2. The coarse screw portion 4, the coarse connecting portion 5 and the fine screw portion 6 are integrally formed, which is conducive to enhancing the connection firmness between the steel back body 1 and the friction lining 9.

[0027] A cutout 7 is provided on the side of the coarse connection part 5. When the user needs to thread the coarse screw part 4 to the steel back body 1, the user can rotate the coarse connection part 5 more smoothly through the cutout 7, thereby making the threaded connection process of the coarse screw part 4 to the steel back body 1 more convenient.

[0028] The diameter of the coarse screw part 4 is the same as that of the coarse connecting part 5 . The height of the coarse screw part 4 is less than or equal to the thickness of the steel back body 1 . The sum of the heights of the coarse connecting part 5 and the fine screw part 6 is less than or equal to the thickness of the friction lining 9 .

[0029] The implementation principle of the brake pad steel back with a threaded copper column in the embodiment of the present application is as follows: the steel back body 1 and the friction lining 9 are stably connected by the threaded copper column, and the contact area and strength between the threaded copper column and the steel back body 1 and the friction lining 9 are increased, so that the friction lining 9 is tightly bonded to the steel back body 1 after the hot pressing process, which is beneficial to improving the shear strength of the brake pad.
