Description
Technical Field
[0001] This utility model relates to the field of brake technology, and more specifically, to an anti-deviation mechanism for a brake. Background Technology
[0002] A brake is a device that decelerates, stops, or keeps a moving part (or moving machinery) at a stop. It is a mechanical part that stops or decelerates moving parts in machinery, commonly known as a brake or brake. A brake mainly consists of a frame, braking components, and operating devices. Due to the development of modern industrial machinery, brakes have evolved into various new structural types. Among them, caliper disc brakes, magnetic powder brakes, and electromagnetic brakes are the most widely used, and are further divided into disc brakes and external block brakes, etc. Traditional disc brakes typically use a single guide structure to limit the movement of the brake pads. Under long-term, high-frequency braking or when subjected to heavy braking loads, the brake pads are prone to lateral displacement or tilting, resulting in a reduction in the contact area between the brake pads and the brake drum (or brake disc). This not only reduces braking efficiency but also causes excessive local wear of the brake pads, shortens the replacement cycle of the brake pads, and increases operating costs. Therefore, an anti-deviation mechanism for brakes is proposed. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-bias mechanism for a brake to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-deviation mechanism for a brake, comprising a fixed disc, two brake plates are provided on one side of the fixed disc, and brake pads are fixedly connected to one side of the brake plates. The brake plates drive the brake pads to move and fit against the external brake drum to achieve the braking effect. A support plate is provided on the inner side of the brake plates, and a mounting plate is fixedly connected to one side of the support plate. The surface of the mounting plate is provided with mounting holes, which facilitate the installation and fixing of the support plate and the mounting plate. The support plate has a U-shaped cross-section. Two limiting plates are provided in the middle of the support plate. A threaded rod is inserted into one side of the support plate, and a threaded head is fixedly connected to one end of the threaded rod. Stabilizing grooves are symmetrically opened on both sides of the limiting plates. Two stabilizing rods are fixedly connected to the middle of the support plate. By rotating the threaded rod, the limiting plates can be controlled to squeeze the wall of the brake plate, thereby limiting the position of the brake plate and preventing the brake plate from shifting or tilting during use, thus improving the stability of the brake plate's movement. Furthermore, the movement of the limiting plates can be limited by the cooperation of the stabilizing rods and the stabilizing grooves, thereby improving the stability of the limiting plates' movement. The support plate has an insertion hole on one side, and a fixing cover is fitted over the screw head. A rod is fixedly connected to one side of the fixing cover. The rod is inserted into the insertion hole, and the fixing cover covers the screw head to limit its position and prevent it from loosening.
[0005] Preferably, a first connecting plate is provided on one side of the fixed plate, and a rotating shaft passing through the fixed plate is fixedly connected to the middle of one side of the first connecting plate. A brake drum is installed on one side of the first connecting plate by bolts, and the first connecting plate is driven by the rotating shaft to make the brake drum move synchronously with the wheel.
[0006] Preferably, the brake plate has an "L" shaped cross-section, and one side wall of the brake plate extends to the middle of the support plate and is located between two limiting plates. The brake plate supports the brake pads, and the limiting plates in the middle of the support plate limit the position of the brake plate.
[0007] Preferably, the top end of the brake plate is connected to a brake cylinder and a return spring, and the bottom end of the brake plate is connected to a second connecting plate. When the brake cylinder is activated, it pushes the top end of the brake plate. With the cooperation of the second connecting plate, the brake plate drives the brake pads to move outward until they are in contact with the brake drum to achieve braking. The return spring can reset the brake plate when the brake cylinder resets.
[0008] Preferably, the stabilizing rod is adapted to the stabilizing groove, and the stabilizing rod passes through the middle of the stabilizing groove. The stability of the movement of the limiting plate is improved by the cooperation of the stabilizing rod and the stabilizing groove.
[0009] Preferably, the threads at both ends of the threaded rod correspond to each other, and the threaded rod passes through the limiting plate and is threadedly connected to the wall of the limiting plate. Rotating the threaded rod controls the movement of the limiting plate, which can squeeze and limit the wall of the brake plate, improve the stability of the movement of the brake plate, and play a role in preventing deviation.
[0010] Preferably, the insertion rod is adapted to the insertion hole, the inner cavity of the fixing cover is adapted to the screw head, one end of the insertion rod passes through the insertion hole and is fixedly connected with a buckle, the insertion rod passes through the insertion hole to limit the fixing cover, and the fixing cover can limit the screw head to prevent the screw head from rotating and loosening, thereby improving the anti-deviation effect.
[0011] The technical effects and advantages of this utility model are as follows: This utility model firstly forms a multi-dimensional limiting system through the wrapping limiting of the "U"-shaped support plate, the limiting of the two sides of the brake plate by the two limiting plates, and the secondary stabilizing cooperation of the stabilizing rod and the stabilizing groove. This effectively limits the offset of the brake plate in the lateral and longitudinal directions, ensures that the brake plate always moves along the preset trajectory, guarantees the contact accuracy between the brake pad and the brake drum, improves braking efficiency, and reduces uneven wear of the brake pad. This utility model also achieves precise adjustment of the spacing between the limiting plates through the reverse thread design at both ends of the threaded rod. Combined with the anti-loosening fixing structure of the fixing cover, the insertion rod and the insertion hole, it can flexibly adjust the limiting gap of the brake plate according to the actual use needs, and prevent the gap change caused by the rotation of the threaded rod after adjustment, ensuring the long-term stability of the limiting gap and avoiding brake jamming or displacement caused by gap problems. In summary, through the interaction of the above-mentioned multiple functions, the lateral and longitudinal offset of the brake plate can be effectively limited, ensuring that the brake plate always moves along the preset trajectory, guaranteeing the contact accuracy between the brake pads and the brake drum, and improving braking efficiency.

[0018] As attached Figure 1-3 As shown, a first connecting plate 2 is provided on one side of the fixed plate 1. A rotating shaft passing through the fixed plate 1 is fixedly connected to the middle of one side of the first connecting plate 2. A brake drum is installed on one side of the first connecting plate 2 by bolts. The cross-sectional shape of the brake plate 3 is set as "L". One side wall of the brake plate 3 extends to the middle of the support plate 5 and is located between two limiting plates 10.
