Description

Technical Field

[0001] The utility model relates to the technical field of anti-lock structures, in particular to a disc brake anti-lock structure. Background Art

[0002] While existing anti-lock braking systems offer adequate braking performance, they still have some limitations in terms of driver comfort. Furthermore, they generate high temperatures during braking, which reduces braking efficiency. This is because existing anti-lock systems employ intermittent braking, meaning the braking process is a combination of multiple, brief friction events between the brake pads and the brake disc.

[0003] Conventional anti-lock braking systems cause drivers to experience a certain degree of vibration, which impacts ride comfort. Furthermore, because the contact area between the brake pad and the friction disc in existing floating caliper brakes is very small, and this is the sole source of braking force to prevent further wheel rotation, the friction force per unit area on the contact surface is very high. Consequently, each time the brake pad rubs against the disc, the brake pad heats up dramatically due to friction. Utility Model Content

[0004] The present utility model aims to provide a disc brake anti-lock braking structure to address the problem that the anti-lock braking method proposed in the above-mentioned background art causes a certain degree of vibration to the driver, thereby affecting comfort to a certain extent. In addition, because the contact area between the brake pad and the friction disc of the existing floating caliper brake is very small, and the braking force preventing further wheel rotation is entirely provided by this contact area, the friction force per unit area on the contact surface is very high. As a result, the temperature of the brake pad increases rapidly due to friction each time the brake pad rubs against the brake disc.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a disc brake anti-lock structure, comprising a brake caliper body, a cylinder body provided at the front end of the brake caliper body, a splined brake shaft provided on the inner wall of the cylinder body, a first gear fixedly connected to the outer wall of the cylinder body, a second gear meshingly connected to the upper end of the first gear, a turbine connected to the middle portion of the second gear, a disc body mechanism sleeved on the outer wall of the splined brake shaft, a pressure mechanism fixedly connected to the front end of the cylinder body, and an input pipe passing through one side of the cylinder body;

[0006] The disk mechanism includes a fixed and movable disk, the inner wall of which is sleeved with the outer wall of the spline brake shaft, and limiting rings are provided on both sides of the fixed and movable disk. The inner wall of the limiting ring is provided with a socket, and the outer wall of the limiting ring is movably connected to the movable disk, and a spline groove is opened through the inner wall of the movable disk.

[0007] Preferably, the rear end of the cylinder is rotatably connected to the front end of the brake caliper body, and the outer wall of the spline brake shaft is plugged into the inner wall of the brake caliper body.

[0008] Preferably, both sides of the fixed disk are fixedly connected to one side of the limiting ring, and the inner wall of the limiting ring is connected to the outer wall of the socket.

[0009] Preferably, the shape of the stator plate is the same as that of the spline brake shaft and is adapted to the inner wall of the cylinder.

[0010] Preferably, the pressure mechanism includes a hydraulic cylinder, the rear end of the hydraulic cylinder is fixedly connected to the front end of the cylinder, the front end of the hydraulic cylinder is provided with an oil filling pipe, the inner wall of the hydraulic cylinder is provided with a movable cavity, and the inner wall of the movable cavity is slidably connected to the piston body.

[0011] Preferably, the front end of the hydraulic cylinder is connected to the rear end of the oil filling pipe, and the inner wall of the hydraulic cylinder is embedded in the outer wall of the movable chamber.

[0012] Preferably, one end of the piston body away from the oil filling pipe passes through the hydraulic cylinder and extends into the barrel.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The disc mechanism enables the equipment to achieve more precise braking control. Since the fixed disc matches the shape of the splined brake shaft and adapts to the inner wall of the cylinder, the fixed disc can rotate synchronously with the brake shaft during braking, thereby ensuring uniformity and stability of braking. The fixed connection between the fixed disc and the limiting ring, and the through-connection between the limiting ring and the socket, provide additional stability for the braking system, effectively preventing unnecessary displacement of the fixed disc in extreme braking situations, thereby ensuring consistency and reliability of the braking effect.

[0015] 2. The set pressure mechanism enables the equipment to achieve precise control of the braking pressure. The piston body, which is slidably connected to the inner wall of the active chamber of the hydraulic cylinder, can respond quickly according to the braking demand and provide the necessary braking force. At the same time, the front end of the hydraulic cylinder is connected to the rear end of the oil filling pipe, ensuring the smooth flow of hydraulic oil and further improving the braking efficiency. It not only improves the braking accuracy and response speed, but also enhances the overall stability of the braking system, thereby providing safe and reliable braking effects under various driving conditions.

This pressure can effectively resist the relative movement between the fixed disc 71 and the movable disc 74, ensuring that the brake does not lock during emergency braking. In addition, in order to ensure the response speed and braking effect of the brake, the setting of the hydraulic cylinder 81 needs to take into account the fluidity of the hydraulic oil and the movement speed of the piston body 84. The embedded connection between the inner wall of the hydraulic cylinder 81 and the movable chamber 83 can reduce the leakage of the hydraulic oil and ensure the sealing of the hydraulic oil. At the same time, the sliding connection setting of the piston body 84 can reduce friction and improve the response speed and braking efficiency of the system.
