Compared with the drum brake, the working surface of the disc brake is flat and heat transfer occurs on both sides. When the disc rotates, it is easy to cool down and is not prone to large deformation. The braking efficiency is relatively stable. After a long time of use, the brake disc has enhanced its braking effect due to high temperature expansion; The drum brake has a single side heat transfer and a large temperature difference between the inner and outer sides, which makes the brake drum prone to deformation. At the same time, after prolonged braking, the brake drum expands due to high temperature, and the braking efficiency is weakened. In addition, the disc brake is simple in structure, convenient in maintenance, and easy to realize automatic adjustment of brake clearance. The main defects caused by the friction disc assembly are: wear and burning of the friction plates; Cracks or looseness of rivets; Spline wear and friction disc deformation (warping), etc.The total thickness of the friction disc assembly varies depending on the model. The standard thickness of the Tieniu-55 tractor is 12 ± 0.1 millimeters, while the standard thickness of the Fengshou-35 tractor is 11.3+0.15 millimeters. When the friction plate is worn due to the total cause of the friction plate, and the total thickness is 3 mm less than the standard size, the friction plate should be replaced in time.

For example, the standard value of rivet head sinking for Tieniu-55 and Fengshou-35 tractors is 1mm, the allowable non repair value is 0.5-0.8mm, and the limit value is 0.25-0.30mm; The standard value of rivet head sinking for Dongfeng-50 and Shanghai-50 tractors is 1.2 millimeters, the allowable non repair value is 0.8 millimeters, and the limit value is 0.3 millimeters. When there are cracks or many loose rivets at the rivet head, and the settlement of the rivet head exceeds the limit value, the friction plate should be replaced. For many years, the fixing method of brake pads for domestic brake products has been using riveting and pressure plate assembly. The riveted connection is time-consuming and not material saving. Although the pressure plate assembly connection is convenient for maintenance and replacement, the utilization rate of the brake pad is low and the waste is serious. The fixing of the brake pad of the electric hydraulic brake adopts a plug-in connection, which overcomes the axial movement of the brake pad and omits the baffle. Not only is it convenient for replacement and maintenance, but the utilization rate of the brake pad can be increased by 30%, and some parts in the fixing are reduced, saving materials and time.For decades, there have been basically two types of brake backtracking adjustment devices in China. One is the limit position by the top screw. When the brake arm is opened, this device needs to repeatedly adjust the top screws on both sides to ensure that the backtracking on both sides is roughly equal, and when opened, the impact force is relatively large. If the automatic compensation mechanism is installed on the brake and the brake pad is worn, the device needs to be continuously adjusted. Otherwise, the top screw limit device will fail. The second is the spring limit, which is difficult to adjust and has a complex structure. Advanced brake products from foreign countries also have equal backlash device mechanisms, but the structural form is to cast the left and right connecting plates of the equal backlash device separately with the left and right brake arms, which is complex in casting structure, cumbersome in processing, and difficult.Actively participating in market competition, our company is determined to inherit and carry forward the excellent tradition of the enterprise, implement management with the spirit of "confidence, self-improvement, pursuit", produce products, provide services, and create performance. The company has gone through an extraordinary journey, and years of practical experience have taught us that in order to gain the ability to grow stronger and larger in the market, enterprises must always adhere to building a brand based on integrity, management, and quality.

A series of specialized devices that can forcibly reduce the driving speed of a car. The braking system mainly consists of four parts: energy supply device, control device, transmission device, and brake. The main function of the braking system is to slow down or even stop a moving car, maintain a stable speed when driving downhill, and keep a stopped car stationary. The braking system is essential for every type of vehicle, and without it, the scene would be unimaginable. In the braking system, brakes are also very important. Generally speaking, the role of front wheel braking is greater, surpassing the contribution of rear wheel braking. The front brakes are generally divided into two types: drum and disc.In general passenger cars, the braking devices of the front and rear wheels are often different. If all four wheels are disc brakes, the front wheels are mostly ventilated disc brakes, and the rear wheels are mostly ordinary disc brakes. If the disc brake is mixed with the drum brake, the front wheel adopts Disc brake, and the rear wheel adopts drum brake. Multiple thrustersUse and MaintenanceThe working condition of the brake shall be checked regularly, and the following items shall be emphasized during the inspection: 1. Whether the brake components can move normally and whether the adjusting nuts are fastened. 2. Whether the components of the thruster are normal and whether the hydraulic oil is sufficient. Is there any oil leakage or seepage. Check if the insulation of the incoming wires is good. 3. The size H1 should not be less than the small dimensions listed in Table 1. If it exceeds the requirements, it must be adjusted immediately, otherwise the braking effect will be lost. 4. Check whether the brake shoe rests on the brake wheel normally, whether the friction surface is in good condition, and whether there is greasy dirt. When the thickness of the brake pad reaches the values in Table 2, the brake pad should be replaced. 5. The temperature of the brake wheel should not exceed 200 ℃. 6.
