[0002] Disc braking is to use a brake caliper to clamp brake pads on a brake disc fixed on an axle or a wheel web, so as to generate friction between the brake pads and the brake disc, convert kinetic energy into heat energy, and transfer it into the brake disc and the disc.

[0003] At present, there are problems such as brake shoe failures, abnormal or irregular wear, insufficient or unqualified brake fluid, oil leakage, and irregular wear, internal quality failures, and wear exceeding the normal service life in horizontal disc brakes. The brake fluid leaks severely at the dust cover of the master cylinder push rod, mostly caused by the inversion or serious damage of the master cylinder cup. The control method of traditional horizontal disc brakes is prone to phenomena such as the overturning of the wheel cylinder cup. Therefore, a structure of an electro-hydraulic horizontal disc brake is needed to improve the above problems. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment, please refer to Figures 1 - 4 The present utility model provides a technical solution:

[0026] A structure of an electro-hydraulic horizontal disc brake includes a main body 1, and a hydraulic brake assembly 2 and an electric control hydraulic assembly 3 are fixedly connected to the side surface of the main body 1.

[0027] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the hydraulic brake assembly 2 includes a hydraulic cylinder 201, and an oil inlet hole 202 is opened at the top of the hydraulic cylinder 201. The electric control hydraulic assembly 3 includes a hydraulic pump 301. A hydraulic motor 302 is fixedly connected to the side surface of the hydraulic pump 301. A relief valve 304 is arranged on the top of the hydraulic pump 301. A filter pipe 305 is fixedly connected to the side surface of the relief valve 304. A hydraulic valve 306 is fixedly connected to the side surface of the filter pipe 305. By combining hydraulic transmission and electric control, the switch of the hydraulic valve 306 is controlled by electricity, so as to control the flow and pressure of the hydraulic oil, and further drive the hydraulic cylinder 201 to realize mechanical movement. Furthermore, through the coordinated cooperation of components such as the hydraulic pump 301, the hydraulic valve 306, the hydraulic cylinder 201 and the hydraulic motor 302, the movement control of the horizontal disc brake is realized. This control method has the advantages of simple structure, stable transmission and flexible control.

[0028] Among them, the output end of the hydraulic cylinder 201 is fixedly connected with an adapter plate 203. The side of the adapter plate 203 is fixedly connected with a brake plate 204. The side of the filter pipe 305 is fixedly connected with a proportional directional valve 307. The bottom of the proportional directional valve 307 is fixedly connected with a delivery pipe 308. The delivery pipe 308 extends into the oil inlet hole 202. A flange plate 303 is arranged on the side of the overflow valve 304. There are two flange plates 303, two adapter plates 203, and two brake plates 204. The overflow valve 304 can maintain the system pressure nearly constant in the hydraulic system, and at the same time make the excess oil in the system return to the fuel tank through overflow, playing a safety protection role. The overflow valve 304 has high sensitivity. Since the valve core surface controlling the opening is a conical surface, when the valve core moves axially slightly, a large opening can be obtained. The valve core has a small volume, small inertia, and flexible movement. The flow capacity of the valve core is large. An annular groove is opened on the bias flow disc at the left end of the valve core. When the oil flows through this groove, the flow direction changes, forming a hydraulic force in the opposite direction to the spring force. The proportional directional valve 307 is different from the traditional on-off valve. The proportional directional valve 307 can precisely control the flow rate of the fluid, thus meeting the requirements of various complex processes. This precision is particularly important in applications that require precise fluid control. They can quickly adjust the fluid flow rate to adapt to the dynamically changing working conditions.

[0029] In this embodiment, as Figure 1 and Figure 4 shown, the main body 1 includes a carrier frame 101. The material of the carrier frame 101 is stainless steel. A threaded rod 102 and a threaded hole pipe 103 are arranged inside the carrier frame 101. The threaded rod 102 extends into the threaded hole pipe 103. The threaded rod 102 is threadedly connected with the threaded hole pipe 103. There are two threaded hole pipes 103 and four threaded rods 102. The threaded connection method has many advantages. First of all, it provides a strong connection force. Due to the design characteristics of the thread, the threaded fastener can provide a stable connection and resist the action of external forces. Secondly, it has good sealing performance. The threaded connection can effectively prevent the leakage of liquids and gases. In addition, the threaded connection has the characteristics of simplicity and reliability and is suitable for various environments.

[0030] Working process of the utility model: When the structure of the electro-hydraulic horizontal disc brake designed by this solution is working, the switch of the hydraulic valve 306 is controlled by electricity, so as to control the flow and pressure of the hydraulic oil, and then drive the hydraulic cylinder 201 to achieve mechanical movement. During the control process, the hydraulic pump 301 is responsible for sucking the hydraulic oil required by the mechanical transmission system from the fuel tank and supplying it to the hydraulic system to form a certain amount of hydraulic energy. The hydraulic valve 306 is responsible for controlling the flow direction, flow rate and pressure of the hydraulic oil, so as to control the movement of the hydraulic cylinder 201. By using the high-pressure hydraulic oil generated by the hydraulic pump 301 and through the control of the hydraulic valve 306, the hydraulic oil is sent into the two chambers of the hydraulic cylinder 201. When the hydraulic oil enters one side chamber of the hydraulic cylinder 201, the hydraulic oil in the other side chamber of the hydraulic cylinder 201 will be discharged, thus pushing the piston of the hydraulic cylinder 201 to move. Vice versa, by controlling the switch of the hydraulic valve 306, the forward and reverse rotation and speed adjustment of the hydraulic cylinder 201 can be realized. The hydraulic motor 302 is a device that uses the pressure and flow rate of the hydraulic oil to drive the rotor to achieve rotational movement. Similarly, the adjustment of torque, speed and direction is realized through the control of the hydraulic valve 306, and then the expansion and contraction of the hydraulic cylinder 201 can be controlled to brake the brake disc located between the two brake plates 204.
