Description
Technical Field
[0001] The utility model relates to the technical field of automobile brake pads, in particular to an automobile brake steel back. Background Art
[0002] Automobile brake pads, also known as automobile brake leathers, refer to friction materials fixed on brake drums or brake discs that rotate with the wheels. The friction linings and friction blocks bear external pressure and generate friction to achieve the purpose of vehicle deceleration. The existing brake pad steel back is mainly used to fix friction materials for easy installation on the brake system. However, due to the limitations of the steel back surface structure, the fixation between the friction material and the steel back is not strong enough, resulting in low safety performance of the brake pad.
[0003] A kind of automobile brake steel back recorded in a Chinese patent (publication number CN214578488U) can improve the bearing capacity of the steel back body and increase the overall strength by setting reinforcing ribs, avoid the steel back from breaking during long-term use, and improve the service life of the steel back. Through the set through holes, the noise generated by the brake pad when working can be transmitted to the cavity at the bottom of the steel back body, and then the sound-absorbing cotton set inside the cavity can absorb the entering noise, thereby reducing the noise generated by the brake pad when working and improving the practicality of the device.
[0004] However, glue is used to bond the steel back to the friction material. After a period of use, the friction material will be worn out and needs to be replaced with a new one. During the replacement process, tools are needed to scrape off the bonding part before replacing the new friction material, which is troublesome and inconvenient to use. Utility Model Content
[0005] In view of the above problems, a car brake steel back is provided, which solves the problem that the friction material is inconvenient to replace by setting a sliding connection mechanism.
[0006] In order to solve the problems of the prior art, the utility model provides an automobile brake steel back, including a steel back body, on which friction material is installed, a sliding connection mechanism is provided between the friction material and the steel back body, and a side plate for limiting the position of the friction material is also slidably provided on the steel back body.
[0007] Preferably, the sliding connection mechanism includes a sliding component for connecting the friction material to the steel back body, and a connecting component for fixing the friction material to the steel back body.
[0008] Preferably, the sliding assembly includes a slide groove, which is arranged at the top of the steel back body, and a sliding block matching with the slide groove is arranged at the lower end of the friction material.
[0009] Preferably, the connecting assembly comprises a connecting block, which is arranged at the bottom of the slide groove, and there are multiple connecting blocks, and the sliding block is provided with a connecting groove matching with the connecting block.

[0012] Preferably, mounting blocks are provided on both sides of the steel back body, and mounting holes for fixing the steel back body are provided on the mounting blocks.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. The utility model aligns the slider of the friction material with the slide groove at the top of the steel back body, and gently pushes the friction material into the slide groove. During the pushing process, the connecting block at the bottom of the slide groove and the connecting groove provided on the slider ensure that the slider slides smoothly along the track of the slide groove until the friction material completely enters the predetermined position, so that the friction material is installed on the steel back body, which improves the convenience of replacing the friction material.
[0015] 2. The utility model uses a vertically arranged connecting block to resist the lateral force generated by the contact between the friction material and the brake disc when in use, providing stable support and positioning for the brake pad, so that the brake pad can maintain a relatively stable position, thereby effectively transmitting the braking force to the brake disc, achieving a safe and reliable braking effect.

DETAILED DESCRIPTION
[0022] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0023] See also Figure 1-Figure 5 As shown, it includes a steel back body 100, on which a friction material 302 is installed, a sliding connection mechanism is provided between the friction material 302 and the steel back body 100, and a side plate 501 for limiting the position of the friction material 302 is also slidably provided on the steel back body 100.
[0024] See also Figure 3 , Figure 4 As shown, a placement groove 400 is provided on the steel back body 100, and a sound-absorbing sponge 401 is installed in the placement groove 400. A through hole 402 is provided at the bottom of the steel back body 100, one end of the through hole 402 is connected to the placement groove 400, and the other end of the through hole 402 is connected to the outside, and a plurality of through holes 402 are provided. When in use, the noise generated when the brake pad is working can be transmitted to the placement groove 400 in the steel back body 100 by setting the through hole 402, and then the noise entering the placement groove 400 can be absorbed by the sound-absorbing sponge 401 set inside the placement groove 400, thereby reducing the noise generated when the brake pad is working and improving the practicability of the device.
[0025] See also Figure 4 , Figure 5As shown, the sliding connection mechanism includes a sliding component for connecting the friction material 302 to the steel back body 100, and a connecting component for fixing the friction material 302 to the steel back body 100. The sliding component includes a slide groove 200, which is opened at the top of the steel back body 100. The lower end of the friction material 302 is provided with a slider 300 that matches the slide groove 200. The connecting component includes a connecting block 201, which is arranged at the bottom of the slide groove 200, and the connecting block 201 is provided with a The slider 300 is provided with a connecting groove 301 that matches the connecting block 201. A lubricating layer is applied between the contact surface of the slide groove 200 and the slider 300. A groove 303 is provided on the friction material 302. When in use, the slider 300 of the friction material 302 is aligned with the slide groove 200 at the top of the steel back body 100, and the friction material 302 is pushed into the slide groove 200. During the pushing process, the connecting block 201 at the bottom of the slide groove 200 and the connecting groove 301 provided on the slider 300 ensure that the slider 300 moves along the slide groove 20 0, until the friction material 302 completely enters the predetermined position, so that the friction material 302 is installed on the steel back body 100, and the connecting block 201 and the connecting groove 301 can reduce the shaking or deviation of the friction material 302 during the braking process, thereby enhancing the stability of the brake pad. When the brake pad is in use, when the friction material 302 contacts the brake disc and generates friction, this friction not only includes the force that prevents the wheel from rotating (usually called braking force), but also may include lateral forces caused by various factors (such as slight unevenness of the brake disc, slight deviation of the installation angle of the brake pad, etc.). These lateral forces may try to cause the brake pad to deviate or shake in the slide groove 200, and the vertically arranged connecting blocks 201 play a key role in this case. They provide stable support and positioning for the brake pad through the cooperation of the connecting groove 301. This design can ensure that during the braking process, even if there is lateral force, the brake pad can maintain a relatively stable position, thereby effectively transmitting the braking force to the brake disc, and achieving a safe and reliable braking effect.
[0026] See also Figure 1-Figure 4As shown, the steel back body 100 is provided with an opening 500, and a side plate 501 is slidably provided in the opening 500. A fixing hole 502 and a positioning hole 504 are provided in the steel back body 100.

When in use, after the friction material 302 is installed, the side plate 501 is inserted into the opening 500. After the side plate 501 reaches the specified position, the fixing bolt 503 and the positioning bolt 505 are used to fix the side plate 501 on the steel back body 100, so that the side plate 501 limits the friction material 302, fixes the friction material 302 in the slide groove 200, and also limits the sound-absorbing sponge 401.
[0027] See also Figure 1 As shown, mounting blocks 101 are provided on both sides of the steel back body 100, and mounting holes 102 for fixing the steel back body 100 are opened on the mounting blocks 101. When in use, the steel back body 100 is installed in a specified position by passing bolts through the mounting holes 102, which is convenient for use.
[0028] The above embodiment discloses a brake steel back for automobiles. When the brake steel back is used, the steel back body 100 is installed at a specified position by passing a bolt through the mounting hole 102, and then the slider 300 of the friction material 302 is aligned with the slide groove 200 at the top of the steel back body 100, and the friction material 302 is pushed into the slide groove 200. During the pushing process, the connecting block 201 at the bottom of the slide groove 200 and the connecting groove 301 provided on the slider 300 ensure that the slider 300 slides smoothly along the track of the slide groove 200 until the friction material 302 completely enters the predetermined position, so that the friction material 302 is pushed into the slide groove 200. 302 is installed on the steel back body 100, and the connecting block 201 and the connecting groove 301 can reduce the shaking or deviation of the friction material 302 during the braking process, thereby enhancing the stability of the brake pad. When the brake pad is in use, when the friction material 302 contacts the brake disc and generates friction, this friction not only includes the force that prevents the wheel from rotating (usually called braking force), but also may include lateral forces caused by various factors (such as slight unevenness of the brake disc, slight deviation of the brake pad installation angle, etc.), which may try to cause the brake pad to deviate in the slide groove 200. The vertically arranged connecting blocks 201 play a key role in this case. They provide stable support and positioning for the brake pads through the cooperation of the connecting grooves 301. This design can ensure that the brake pads can maintain a relatively stable position even if there is a lateral force during the braking process, thereby effectively transmitting the braking force to the brake disc to achieve a safe and reliable braking effect. The sound-absorbing sponge 401 is then installed in the placement groove 400. By setting the through hole 402, the noise generated by the brake pads during operation can be transmitted to the placement groove 400 in the steel back body 100. The sound-absorbing sponge 401 arranged inside the placement groove 400 can absorb the noise entering the placement groove 400, reduce the noise generated when the brake pad is working, and improve the practicality of the device. Finally, the side plate 501 is inserted into the opening 500. After the side plate 501 reaches the specified position, the side plate 501 is fixed to the steel back body 100 using the fixing bolts 503 and the positioning bolts 505, so that the side plate 501 limits the friction material 302, fixes the friction material 302 in the slide groove 200, and also limits the sound-absorbing sponge 401.
