DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] In this technical solution, a disc brake assembly for a motor vehicle includes a disc brake disc 1 and a connecting ring 2. A convex block 3 is installed on the outer side wall of the connecting ring 2. A relief groove 4 is opened on the inner side wall of the disc brake disc 1. The disc brake disc 1 is sleeved on the outside of the connecting ring 2, and the convex block 3 can be inserted into the relief groove 4.

[0025] A through hole 5 is opened on the side wall of the convex block 3, a threaded hole 6 is opened on the inner side wall of the relief groove 4, a bolt 7 is inserted and installed in the through hole 5, and the bolt 7 is screwed and installed in the threaded hole 6.

[0026] A retaining cap 8 is inserted and installed in the through hole 5. The retaining cap 8 can be buckled on the outside of the bolt head of the bolt 7. A positioning block 9 is installed on the inner side wall of the retaining cap 8. The positioning block 9 can be attached to the outer side wall of the bolt head of the bolt 7. A wedge block 10 is installed on the outer side wall of the retaining cap 8. A clamping groove 11 is opened on the inner wall of the through hole 5. The wedge block 10 can be inserted and installed in the clamping groove 11.

[0027] In this technical solution, when the retaining cap 8 is inserted into the through hole 5 and sleeved on the outside of the bolt head of the bolt 7, the positioning block 9 inside the retaining cap 8 will be closely attached to the side wall of the bolt head to position the bolt 7. Then, the wedge block 10 outside the retaining cap 8 will be inserted into the clamping groove 11. At this time, the retaining cap 8 cannot rotate in the through hole 5. At the same time, due to the setting of the positioning block 9, the bolt 7 will not rotate either, thus avoiding the loosening of the connection between the disc brake disc 1 and the connecting ring 2 and affecting the driving safety of the vehicle.

[0028] In some technical solutions, a sealing ring 12 is attached to the side wall of the retaining cap 8. The cross section of the sealing ring 12 is conical, and the sealing ring 12 can be attached to the inner side wall of the through hole 5.

[0029] In this technical solution, a sealing ring 12 is also provided outside the retaining cap 8 of the device. Through the close attachment of the sealing ring 12 to the inner wall of the through hole 5, it can isolate the bolt 7 from the outside, prevent the bolt 7 from contacting external accumulated water or rainwater, and cause rust, which affects the later disassembly and replacement of the disc brake disc 1.

[0030] In some technical solutions, heat dissipation holes 13 are formed in the side wall of the disc brake disc 1. The heat dissipation holes 13 penetrate through the side wall of the disc brake disc 1. Main mounting holes 14 and auxiliary mounting holes 15 are formed in the side wall of the connecting ring 2. A screw on an external axle can penetrate through the side wall of the connecting ring 2 through the main mounting hole 14 and the auxiliary mounting hole 15.

[0031] In this technical solution, since the disc brake brakes by the friction between the disc brake disc 1 and the brake pads, a large amount of heat will be generated by friction in the disc brake disc 1 during the braking process. Therefore, by forming heat dissipation holes 13 in the disc brake disc 1, the disc brake disc 1 can dissipate heat faster.

[0032] In some technical solutions, a groove 16 is formed in the side wall of the sealing ring 12. The groove 16 is annular. An elastic member 17 is inserted and mounted in the groove 16. The elastic member 17 can support the sealing ring 12.

[0033] In this technical solution, by arranging the elastic member 17 inside the sealing ring 12, it can support the sealing ring 12, so that the sealing ring 12 can be closely attached to the inner side wall of the through hole 5. The elastic member 17 proposed in this article is a solid rubber ring.

[0034] In some technical solutions, a sealing ring 18 is mounted on the inner side wall of the disc brake disc 1. The sealing ring 18 can be attached to the outer side wall of the connecting ring 2.

[0035] In this technical solution, both side walls of the sealing ring 18 are attached to the disc brake disc 1 and the connecting ring 2 respectively, so as to block the connection between the two and prevent external rainwater or impurities from entering.

[0036] In some technical solutions, the retaining cap 8 is made of plastic, and the cross sections of the wedge block 10 and the card slot 11 are both triangular.

[0037] Working principle: The disc brake disc 1 is sleeved and mounted on the outer side of the connecting ring 2, and the convex block 3 on the outer side of the connecting ring 2 is snapped into the relief groove 4. Then, the bolt 7 is inserted into the through hole 5 and screwed into the threaded hole 6 to connect the disc brake disc 1 and the connecting ring 2. When the retaining cap 8 is inserted into the through hole 5 and sleeved on the outer side of the bolt head of the bolt 7, the positioning block 9 inside the retaining cap 8 will be closely attached to the side wall of the bolt head to position the bolt 7. Then, the wedge block 10 on the outer side of the retaining cap 8 will be snapped into the card slot 11. At this time, the retaining cap 8 cannot rotate in the through hole 5. At the same time, due to the arrangement of the positioning block 9, the bolt 7 will not rotate either, thus preventing the connection between the disc brake disc 1 and the connecting ring 2 from loosening and affecting the driving safety of the vehicle;

[0038] Meanwhile, the sealing ring 12 fits tightly with the inner wall of the through hole 5, which can isolate the bolt 7 from the outside, preventing the bolt 7 from contacting external accumulated water or rainwater, rusting, and affecting the later disassembly and replacement of the disc brake 1.
