Technical Field

[0001] The utility model relates to the technical field of braking devices, in particular to a brake shoe that can effectively prevent detachment. Background Art

[0002] A brake shoe is a component that is pushed outwards by the action of a brake cam or a push rod and presses against the brake drum to produce a braking effect. It is usually installed in a drum brake system, contacts the inner wall of the brake drum, and slows down the rotation speed of the wheel through friction, thereby achieving the deceleration and stop of the vehicle. The brake shoe is an indispensable part of the vehicle braking system and is crucial for ensuring driving safety.

[0007] To achieve the above purposes, the utility model is realized through the following technical solutions: A brake shoe that can effectively prevent detachment includes a brake shoe body.

[0014] Beneficial effects

[0015] The utility model provides a brake shoe that can effectively prevent detachment. Compared with the prior art, it has the following

[0016] Beneficial effects:

[0017] (1) A brake shoe that can effectively prevent detachment. By setting up an anti-detachment component, the clamping joint improves the rotation of the support block on the rotating shaft, causing the clamping joint to move into the card slot. The clamping joint contacts the edge of the card slot through the clamping block and contracts into the partition through the spring, enabling the clamping joint to enter the card slot. During disassembly, the pull plate is pulled backward, causing the push plate to move backward through the push rod, driving the connecting rope to move through the pulley group, making the clamping block contract into the partition, and causing the clamping joint to pop out of the card slot through the torsion spring on the rotating shaft. This solves the problem that during the use of a brake shoe block, since there are no shielding plates on both sides of the brake shoe, long-term use will cause the brake shoe to move to both sides, resulting in displacement of the brake shoe and thus the risk of detachment. It achieves the effect of fixing the side of the friction plate through the anti-detachment component, thereby preventing the friction plate from displacing during long-term use.

[0018] (2) A brake shoe that can effectively prevent detachment. By setting up a heat dissipation component, the heat dissipation fins are installed in the installation slot in the brake shoe body through the limit blocks. Through the cooperation of the limit bolts and nuts, the heat dissipation fins can be fixed between the friction plate and the brake shoe body, thereby dissipating the heat generated after the friction of the friction plate. This solves the problem that during the use of the existing brake shoe with effective anti-detachment, the heat generated after long-term friction between the friction plate and the inside of the brake drum will damage the internal parts of the brake shoe, resulting in a reduced service life of the parts. It achieves the effect of dissipating the heat generated by the friction of the friction plate through the heat dissipation component, thereby reducing the damage of internal parts due to overheating.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1:

[0026] Please refer to Figures 1-4 , a brake shoe that can effectively prevent detachment, including a brake shoe body 1, an anti-detachment component 2 is installed on the top of the brake shoe body 1, a heat dissipation component 3 is installed inside the brake shoe body 1, and a friction plate 4 is fixed on the outside of the heat dissipation component 3;

[0027] The anti-detachment component 2 includes a mounting seat 21, a rotating shaft 22 is fixed on the top of the mounting seat 21, a support block 24 is fixed in the middle of the rotating shaft 22, a clamping joint 25 is fixed on the side of the top of the support block 24, a sliding groove 26 is opened inside the clamping joint 25, one end of the sliding groove 26 is fixed with a telescopic rod 27, the other end of the telescopic rod 27 is fixed with a push rod 29, the other end of the push rod 29 is fixed with a push plate 211, and connecting ropes 212 are fixed on both sides of the other end of the push plate 211, and the other end of the connecting rope 212 is fixed with a clamping block 213;

[0028] A partition plate 215 is fixed on the side of the sliding groove 26 away from the telescopic rod 27, the other end of the partition plate 215 is fixed with a spring 214, the other end of the spring 214 is fixed with a clamping block 213, and there is a distance between the spring 214 and the connecting rope 212. The partition plate 215 can separate the space between the sliding groove 26 and the spring 214;

[0029] A pulley group 216 is fixed on the side of the sliding groove 26, and the connecting rope 212 is slidably connected to the pulley group 216. The material of the connecting rope 212 is steel wire. The connecting rope 212 made of steel wire can make the service life of the connecting rope 212 longer and the wear resistance higher. It can be in friction with the pulley group 216 for a long time, and the connecting rope 212 is in a taut state when it is on the pulley group 216;

[0030] A pull plate 210 is fixed on the top of the push rod 29 near the telescopic rod 27. The pull plate 210 penetrates through the top of the clamping joint 25. A telescopic spring 28 is sleeved on the telescopic rod 27. Installation bolts 217 are threadedly connected to both sides of the top of the mounting seat 21. Torsion springs 23 are sleeved on both ends of the outside of the rotating shaft 22. Card slots 218 are opened at both the upper and lower ends of the brake shoe body 1. The installation bolts 217 can make the mounting seat 21 be freely disassembled, and the torsion springs 23 can make the rotating shaft 22 have an automatic resilience force.

[0031] In this embodiment, when the friction plate 4 is installed on the brake shoe body 1, the support block 24 rotates through the rotating shaft 22. When the clamping joint 25 enters the clamping groove 218, when the clamping block 213 contacts the notch of the clamping groove 218, the clamping block 213 contracts into the partition plate 215 through the spring 214, so that the clamping joint 25 is clamped in the clamping groove 218, and both the upper and lower ends of the friction plate 4 are clamped by the clamping joint 25, so that the friction plate 4 can be fixed. After the friction plate 4 rubs against the brake drum for a long time, the friction plate 4 will not shift to the side.

When the clamping block 213 completely contracts into the interior of the partition plate 215, the clamping joint 25 is directly ejected from the clamping groove 218 due to the torsion generated by the rotation of the torsion springs 23 on both sides of the rotating shaft 22, so that the friction plate 4 can be disassembled.

[0032] Embodiment Two:

A limiting bolt 33 is threadedly connected inside the limiting block 32, and a nut 34 is threadedly connected to one end of the limiting bolt 33;

[0034] An installation groove 35 is opened inside the brake shoe body 1. Threaded grooves 37 are opened at both inner ends of the brake shoe body 1. Heat dissipation holes 36 are opened on the heat dissipation fins 31. The shape of the heat dissipation fins 31 is arc-shaped. The heat dissipation holes 36 can make the heat dissipation effect of the heat dissipation fins 31 more significant and at the same time accelerate the heat dissipation efficiency. The arc-shaped heat dissipation fins 31 result in the best heat dissipation effect.

[0035] In this embodiment, when installing the brake shoe body 1, through the limiting blocks 32 at both ends of the heat dissipation fins 31, the heat dissipation fins 31 can be clamped and installed in the installation groove 35 opened inside the brake shoe body 1, so that the holes on the limiting blocks 32 coincide with the threaded grooves 37 opened on the inner side of the brake shoe body 1. Then, the limiting bolt 33 is used to threadedly fix the limiting block 32 and the brake shoe body 1 through the threaded groove 37, and the nut 34 is used to fix the limiting bolt 33. Then, the friction plate 4 is clamped on the outer surface of the heat dissipation fins 31, and the friction plate 4 is fixed by the anti-detachment assembly 2, thereby preventing the friction plate 4 from falling off. The heat dissipation holes 36 opened on the surface of the heat dissipation fins 31 can dissipate the heat generated after the friction plate 4 rubs for a long time, thereby protecting the parts inside the brake shoe body 1 from being affected by high temperature.
