Description

Technical Field

[0001] The utility model relates to the technical field of high-precision automobile braking, in particular to a high-precision automobile braking structure. Background Art

[0002] A car is a modern means of transportation, which is mainly composed of engine, chassis, body and electrical equipment. The manufacturing process of a car includes stamping, welding, painting, assembly and testing. Each step has its specific function and importance, and finally completes the manufacturing of the car. High-precision cars mainly refer to cars that use high-precision technology and equipment in the manufacturing process. This high-precision manufacturing process ensures that the various parts and components of the car can be precisely matched, thereby improving the performance, safety and reliability of the car. In the field of automobile manufacturing, the application of high-precision technology covers many aspects.

[0003] The common high-precision automobile braking structure mainly includes two parts: the brake and the brake transmission device. The brake usually includes a brake drum or brake disc and a brake shoe or brake pad. When the brake pedal is pressed, the brake transmission device transmits the braking force to the brake, so that the brake shoe or brake pad is in close contact with the brake drum or brake disc and generates friction, thereby slowing down or stopping the rotation of the wheel. This is the common high-precision automobile braking structure and usage. In the traditional high-precision automobile braking structure, frequent braking will cause the brake drum and brake pad to heat up rapidly due to friction, and high temperature will affect the toughness and ductility of the metal, which can easily cause the brake pad to wear faster or even directly break. For example, patent number CN220053756U is an anti-runaway automobile braking structure. The micro water pump will pump out a small stream of water from the car water tank, and spray water on two sets of brake pads at the same time through the bifurcated nozzle to achieve a cooling effect. However, in this method, since water is poured when the temperature of the brake pad is high, the water droplets evaporate instantly, the temperature will drop rapidly, causing the brake pad to deform, thereby affecting its existence and braking performance, and shortening its service life, causing premature failure or damage, thereby affecting the driving safety of the car. Therefore, a high-precision automobile brake structure is proposed. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the utility model provides a high-precision automobile brake structure to solve the technical problems of deformation and shortened service life of the brake pads when water is poured at high temperature.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-precision automobile braking structure, comprising:

[0008] A brake drum and a shaft body arranged at the center of the front face of the brake drum, and a brake pad is arranged on the inner wall of the brake drum;

[0009] The heat absorbing pipe is arranged on the back of the inner cavity of the brake drum, and connecting rods are installed around the upper part of the surface of the heat absorbing pipe and connected with the inner wall of the brake drum;

[0010] The inlet pipe and the outlet pipe are arranged at the center of the upper and lower parts of the back of the brake drum, and the rear ends of the inlet pipe and the outlet pipe penetrate the outer wall of the brake drum and are connected with the heat absorbing pipe. The front ends of the surfaces of the inlet pipe and the outlet pipe are provided with electromagnetic valves, and the front ends of the inlet pipe and the outlet pipe are provided with connecting flanges. The inlet pipe and the outlet pipe are connected with the external micro pump body through the connecting flange, and the micro pump body is connected with the car water tank, and the electromagnetic valve is opened to allow the liquid to flow into the heat absorbing pipe and absorb the heat generated by the brake pad in the brake drum, and then the heat-absorbing liquid is discharged by the outlet pipe. On the one hand, when the brake pad is cooled, the liquid can be prevented from directly contacting with the brake pad, which can cause the deformation of the brake pad and shorten the service life. On the other hand, a micro temperature sensor and a controller can be added to control the operation of the external micro pump body on the car, which can not only realize accurate and high-precision operation, but also can timely discharge and inject the heat exchange liquid, thereby improving the heat dissipation effect of the brake pad.

[0011] Preferably, brake shoes are provided on both sides of the inner cavity center of the brake drum, and a connecting plate is installed at the inner cavity center of the brake drum, and a connecting piece is provided at the bottom of the connecting plate. When the brake shoe is subjected to actuating force at one end, it can swing outward around the fulcrum at the other end and press against the inner circumferential surface of the brake drum to generate a friction torque.

[0012] Preferably, the heat absorbing tube is designed as a whole in an annular shape, and the upper and lower center positions of the back of the heat absorbing tube are connected to the corresponding ends of the inlet tube and the discharge tube respectively. The inlet tube injects liquid into the top of the heat absorbing tube, and the liquid after heat exchange is completed is discharged through the discharge tube, so as to realize the circulation of liquid and avoid the phenomenon that the liquid is difficult to be discharged in the heat absorbing tube, resulting in reduced heat dissipation effect.

[0013] Preferably, a fixing plate is transversely mounted at the center of the upper and lower parts of the back of the brake drum, and a guide rod is longitudinally inserted at the center of the top of the fixing plate. The guide rod moves along the fixing plate on the brake drum.

[0014] Preferably, the top of each guide rod is provided with a limit plate, which fits with the fixed plate, and the outer surface of each guide rod is provided with a compression spring, one end of which fits with the fixed plate. The limit plate prevents the guide rod from separating from the fixed plate, and the guide rod is tightly fitted with the limit plate under the action of the compression spring.

[0015] Preferably, the bottom ends of the guide rods are all equipped with arc clamps, which are connected to the rear ends of the surfaces of the inlet pipe and the discharge pipe, and the other end of the extrusion spring fits the arc clamps. Under the action of the extrusion spring, the guide rod drives the arc clamps to fit tightly to the surfaces of the corresponding inlet pipe and the discharge pipe, thereby ensuring the stability of the connection between the inlet pipe and the discharge pipe and the micro pump body, and avoiding the occurrence of shaking or even collision and damage when the car is driving.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a high-precision automobile braking structure, which has the following beneficial effects:

[0018] The brake structure of the high-precision automobile connects the inlet pipe and the outlet pipe with the external micro pump body through the connecting flange, and the micro pump body is connected with the automobile water tank, and the solenoid valve is opened to allow the liquid to flow into the heat absorption pipe and absorb the heat generated by the brake pad in the brake drum, and then the heat-absorbing liquid is discharged by the outlet pipe. In this way, on the one hand, when the brake pad is cooled, direct contact between the liquid and the brake pad can be avoided, which leads to deformation of the brake pad and shortened service life. On the other hand, a micro temperature sensor and a controller can be added to control the operation of the external micro pump body on the automobile, which not only realizes accurate high-precision operation, but also can discharge and inject the heat exchange liquid in time, thereby improving the heat dissipation effect of the brake pad.
