DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The preferred embodiment of the high-efficiency automotive disc brake lining provided by the utility model is as follows: Figures 1 to 6As shown: A high-efficiency automotive disc brake lining comprises a base plate 1, a back side of the base plate 1 is provided with reserved grooves 5 at equal intervals, fastening bolts 8 are movably connected inside the reserved grooves 5, limiting components 4 are arranged at equal intervals inside the base plate 1, a clamping groove 7 is provided on the front side of the base plate 1, a back plate 6 is movably connected inside the clamping groove 7, bolt holes 11 threadedly matched with the fastening bolts 8 are provided on the back side of the back plate 6 at equal intervals, a heat insulating layer 13 is fixedly connected at the middle position of the front side of the back plate 6, and a friction plate 2 extending to the outside of the base plate 1 is fixedly connected to the front side of the heat insulating layer 13.

[0029] The limiting component 4 includes a fixing groove 401, which is opened inside the bottom plate 1. A fixing spring 404 is movably connected at the middle position inside the fixing groove 401. Both ends of the fixing spring 404 are fixedly connected with sliding blocks 402. One end of the sliding block 402 is fixedly connected with a limiting block 405 extending to the inside of the reserved groove 5. One end of the top of the sliding block 402 is fixedly connected with a shifting block 403. By utilizing the elastic force of the fixing spring 404, the sliding block 402 slides to drive the limiting block 405 to return to its original position, thereby limiting the nut of the fastening bolt 8 to prevent the thread of the fastening bolt 8 from loosening and affecting the firmness and stability of the installation of the friction plate 2.

[0030] In this embodiment, a sliding structure is formed between the sliding block 402 and the lower end inside the fixed groove 401. The cross-section of the fixed groove 401 is convex. The sliding of the sliding block 402 and the lower end inside the fixed groove 401 improves the stability of the back and forth sliding of the limit block 405.

[0031] In this embodiment, the length of the fixed groove 401 is greater than the length of the limit block 405, and the horizontal plane at the top of the shift block 403 is lower than the horizontal plane at one end of the fixed groove 401. By using a longer fixed groove 401, the shift block 403 has enough moving space to drive the limit block 405 to detach from the reserved groove 5.

[0032] In this embodiment, a rubber ring 14 is fixedly connected to one end of the surface of the fastening bolt 8, and the cross-section of the rubber ring 14 is O-shaped. The O-shaped rubber ring 14 is used to increase the clamping force between the nut of the fastening bolt 8 and the inner wall of the reserved groove 5, thereby reducing the possibility of thread loosening of the fastening bolt 8.

[0033] In this embodiment, a locking structure is formed between the back plate 6 and the inside of the slot 7. The cross-sections of the back plate 6 and the slot 7 are arc-shaped.

[0036] In addition, the cross-section of the heat dissipation groove 12 is arc-shaped, and both ends of the heat dissipation groove 12 extend to the outside of the friction plate 2. The heat dissipation groove 12 extending to the outside of the friction plate 2 facilitates the flow of air inside and outside the friction plate 2, and facilitates ventilation and heat dissipation of the friction plate 2 itself.

[0037] The working principle and use process of the utility model are as follows: first, the back plate 6 is clamped into the inside of the card slot 7, and the positioning block 10 is clamped into the inside of the positioning slot 9, so as to improve the accuracy and firmness of the clamping installation between the friction plate 2 and the bottom plate 1, and then the sliding block 402 is driven to slide and compress the fixing spring 404 by toggling the toggle block 403 and drive the limit block 405 to slide until it is completely separated from the inside of the reserved slot 5, and then the fastening bolt 8 is inserted into the inside of the reserved slot 5 and screwed into the inside of the bolt hole 11, so as to achieve the firm fixation of the back plate 6 and the inside of the card slot 7, and ensure the firm and stable installation of the friction plate 2, and then the toggle block 403 is loosened, and the elastic force of the fixing spring 404 is used to make the sliding block 402 slide and drive the limit block 405 to return to its original position, so as to limit the nut of the fastening bolt 8, so as to prevent the thread of the fastening bolt 8 from loosening and affecting the firmness and stability of the installation of the friction plate 2;

[0038] At the same time, the heat dissipation groove 3 is used to improve the heat dissipation effect of the surface of the friction plate 2, and the arc-shaped heat dissipation groove 12 can ventilate and dissipate heat inside the friction plate 2, further improving the heat dissipation effect of the friction plate 2 itself. At the same time, the heat insulation layer 13 is provided to avoid continuous heat transfer and extend the service life of the friction plate 2.
