Abstract
Description
Technical Field
[0001] This utility model relates to the field of brake shoe technology, specifically a brake shoe that allows for quick replacement of brake pads. Background Technology
[0002] A hub brake, also known as a drum brake, is a type of drum brake used in vehicle braking systems. It achieves braking by working in conjunction with the wheel hub. Most electric vehicles use hub brakes. Hub brakes typically work by externally cranking a camshaft, which in turn rotates the internal brake shoes. This rotation applies a pushing force to one end of two opposing crescent-shaped brake shoes, the other ends of which are connected and fixed to the hub brake box by pins. The brake shoes then rotate around these other ends, causing the brake pads on the brake shoes to press against the inner wall of the drum, generating friction to stop the wheel's rotation and thus braking the electric vehicle.
[0003] Currently, brake pads on commercially available brake pads are usually fixedly bonded to the brake pads, making them difficult to separate. This means that when brake pads are severely worn and need replacement, the brake pads must also be replaced, resulting in waste and high maintenance costs. To address this issue, we have proposed a brake pad design that allows for quick brake pad replacement. Utility Model Content
[0004] The purpose of this invention is to provide a brake shoe that allows for quick replacement of brake pads, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a brake shoe with quick-replacement brake pads, comprising:
[0006] The shoe block body has an mounting block on it, and a brake pad is mounted on the mounting block. Two symmetrically arranged slots are formed in the center of the mounting block. Two insert rods are fixedly welded to the brake pad, and each insert rod is movably inserted into one of the two slots. A locking groove is formed at the end of each insert rod away from the brake pad. A through groove is formed on the shoe block body, and a locking rod is movably inserted into the through groove. Both ends of the locking rod are movably inserted into the locking groove, and an opening is formed in the middle of the locking rod. A groove is formed on the side wall of the shoe block body, and a threaded groove is formed in the groove, penetrating the through groove. A locking bolt is placed in the groove, and the locking bolt passes through the through groove and is threaded into the threaded groove of the groove.
[0007] Preferably, a plurality of reinforcing ribs are fixedly welded to the hoof block body, and the reinforcing ribs are fixedly welded to the mounting block.
[0008] Preferably, multiple heat sinks are fixedly bonded to the mounting block.
[0009] Preferably, the mounting block and the hoof block body are integrally formed.
[0010] Preferably, both the hoof block body and the mounting block are made of steel.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] When using this invention, if brake pads need to be replaced, a tool can be used to first remove the locking bolt from the groove to release the locking rod from its position. Then, the locking bolt is used to push the locking rod out of the through groove, causing it to disengage from the two insert rods. Finally, the brake pad insert rod can be pulled out of the slot. This allows for quick removal of the brake pads. During installation, simply reverse the above steps. This makes it easy to replace the brake pads and avoids the waste and high maintenance costs associated with replacing brake shoes along with the brake pads when they are severely worn.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3 This utility model provides a technical solution: a brake shoe with quick-replacement brake pads, comprising:
[0019] The shoe block body 1 has an mounting block 2 on it, a brake pad 3 on it, and two symmetrically arranged slots 4 in the middle of the mounting block 2. Two insert rods 5 are fixedly welded to the brake pad 3 and are movably inserted into the two slots 4 respectively. A locking groove 6 is formed at the end of the insert rod 5 away from the brake pad 3. A through groove 7 is formed on the shoe block body 1, and a locking rod 8 is movably inserted into the through groove 7. Both ends of the locking rod 8 are movably inserted into the locking groove 6 respectively. A through opening 9 is formed in the middle of the locking rod 8. A groove 10 is formed on the side wall of the shoe block body 1, and a threaded groove is formed in the groove 10. The threaded groove passes through the through groove 7, and a locking bolt 11 is provided in the groove 10. The locking bolt 11 passes through the through opening 9 and is threaded into the threaded groove of the groove 10.
[0020] Multiple reinforcing ribs 12 are fixedly welded to the main body 1 of the hoof block. The reinforcing ribs 12 are fixedly welded to the mounting block 2. The reinforcing ribs 12 can strengthen the support of the mounting block 2 and prevent the mounting block 2 from being deformed by pressure.
[0021] Multiple heat sinks 13 are fixedly bonded to the mounting block 2. The heat sinks 13 facilitate the rapid heat dissipation of the mounting block 2, so that when the brake pad 3 receives heat generated by friction, it can be conducted to the mounting block 2 and dissipated through the multiple heat sinks 13, thereby improving the heat dissipation effect of the brake pad 3.
[0022] The mounting block 2 and the hoof block body 1 are integrally formed.
[0023] Both the brake shoe body 1 and the mounting block 2 are made of steel, which has high hardness and improves the service life of the brake shoe.
[0024] Working principle: When using this utility model, if it is necessary to replace the brake pad 3, the locking bolt 11 can be removed from the groove 10 to release the restriction on the locking rod 8. Then, the locking bolt 11 can be used to push the locking rod 8 out of the through groove 7, so that the locking rod 8 is disengaged from the two insert rods 5. Then, the insert rod 5 of the brake pad 3 can be pulled out of the slot 4. This achieves quick removal of the brake pad 3. When installing, simply reverse the above steps. This allows the brake pad 3 to be replaced conveniently, avoiding the problem of having to replace the brake shoes together when the brake pad 3 is severely worn and needs to be replaced, which would cause waste and high maintenance costs.
