Pneumatic brake is a very important accessory in our daily life, which is very commonly used and plays an indispensable role. If there is a problem with the brake, the safety of the motor vehicle will face great danger. So whether your car is a private car, a truck, a truck, or a crane, brakes will be installed on it. What are the components of pneumatic brakes? Any braking system has the following four basic components: 1. Control device, including various components that generate braking actions and control braking effects. 2. Transmission device, including various components that transmit braking energy to the brake 3. Brake, a component that generates a force (braking force) that impedes the movement or tendency of a vehicle, including the deceleration device in the auxiliary braking system. 4. Energy supply device, including various components that supply and regulate the energy required for braking and improve the state of the energy transmission medium. In summary, it is a component of the brake system. Do you understand it now? We cannot just use the brake and neglect its maintenance to avoid damaging its service life due to improper daily maintenance! That's all for introducing this knowledge to everyone.
At first glance, the term 'brake' may seem unfamiliar to many people. In fact, brakes are very simple, and they are what we usually refer to as brakes. Do you understand this statement? There are many types of brakes, including hydraulic brakes, block brakes, disc brakes, and many more. So who knows what the main faults of disc brakes are? The pressure on the barometer rises slowly. Main reasons: (a) Pipeline leakage; (b) The air pump is not working properly; (c) The one-way valve is corroded and stuck; (d) The oil drain bolt of the oil-water separator is not tightly closed or the pressure regulating valve is leaking air. Methods for cleaning up problems; Firstly, the pipeline should be cleaned of any air leaks, and then the operation status of the air pump should be checked. Remove the exhaust pipe of the air pump and press the outlet tightly with your thumb. If the exhaust pressure is low, it indicates that there is a problem with the air pump. If the air pump is in excellent working condition, check the oil drain plug or pressure regulating valve of the oil-water separator to prevent bypass, and clean up the problem after inspection. Finally, check the two one-way valves in the three-way connector again. If the one-way valves are stuck, it will cause the air storage cylinder to be unable to intake or intake slowly. (2) Lack of braking force and weakness. Main reasons: (a) Brake oil leakage; (b) There is air in the brake oil circuit; (c) The wheel hub oil seal is damaged, and there is oil stains on the clamp disc; (d) Severe brake wear and tear, with burnt conflict surfaces; (e) The air pressure adjustment in the pneumatic circuit is too low. The above problems can be repaired, adjusted, or replaced with parts according to their respective causes before cleaning. (3) Run off track after braking. The direct cause of deviation is the unequal braking torque between the two wheels. Common causes of the problem include: (a) The oil stains on the brake caliper disc are severe, and the coefficient of the conflict body is severely reduced, resulting in an unbalanced braking torque. At this moment, the oil stains on the brake caliper disc should be removed; (b) The cylinder piston is stuck and cannot operate. Press the brake pedal while still, investigate the condition of the cylinder operation, and disassemble and inspect as necessary. (4) Brake card issuing. Symptoms of the problem: The loader has difficulty starting and walking, and after parking, touching the clamp plate with your hand causes it to heat up. Main reasons: (a) After parking the conflict film, touch the clamp plate with your hand, and the clamp plate will heat up. Main reasons: (b) The wear and tear of the conflict plate has become thinner, the dust ring is damaged and water has entered, and the piston is corroded and stuck; (c) The reset tension spring in the booster pump is weak or broken, and high-pressure oil cannot flow. (5) The booster pump sprays brake fluid. Symptoms of the problem: When applying the brake, oil mist sprays out. Reason for the outbreak: (a) The brake light switch is damaged, and high-pressure oil is spraying out from the switch interface. Replacing the switch can solve the problem. (b) The piston rod length of the booster pump is too long. This situation can occur when replacing the booster pump assembly. The reason is that the piston rod adjustment is too long, resulting in excessive piston stroke during booster pump operation. Brake fluid flows back into the booster pump from the drain hole and sprays out. During installation, the piston stroke should be measured to determine the length of the piston rod. Common problems with disc brakes during use include air resistance, lack of braking force, and noise during braking. Air resistance The heating part of the disc brake is concentrated on a very narrow brake pad, and its unit pressure is higher than that of the drum brake. The brake pad and the piston of the caliper body directly touch each other, so the heat during braking is easily transferred to the brake fluid. In this way, the disc brake can easily experience air resistance. However, if corresponding measures are adopted, the occurrence of air resistance symptoms can also be prevented. 1. Prevent the boiling point of brake fluid from decreasing
摩擦分类 ①摩擦式制动器。靠制动件与运动件之间的摩擦力制动。 ②非摩擦式制动器。制动器的结构形式主要有磁粉制动器(利用磁粉磁化所产生的剪力来制动)、磁涡流制动器(通过调节励磁电流来调节制动力矩的大小)以及水涡流制动器等。 制动件结构形式 又可分为外抱块式制动器、内张蹄式制动器、带式制动器、盘式制动器等; 制动件工作状态 还可分为常闭式制动器(常处于紧闸状态，需施加外力方可解除制动)和常开式制动器(常处于松闸状态，需施加外力方可制动); 操纵方式 也可分为人力、液压、气压和电磁力操纵的制动器。

What should I do if there is noise from the disc brake
What is a brake? A brake is what we refer to as a brake. Of course, the application of a brake is very extensive, and it is commonly used in movable mechanical equipment. There are many types of brakes, one of which is a disc brake. People who have applied disc brakes may encounter noise from disc brakes. What should they do? If there is a "squeak, squeak" noise when braking with a disc brake, the following methods can be used to eliminate it: 1. Add an anti noise plate between the brake caliper piston and the brake lining to create an inclination on the piston. Then ensure that the brake pads and brake discs have a flexible touch during braking, so that the brake pads do not produce abnormal noise under normal wear conditions. 2. Select brake pad materials with softer and lower density for the brake. 3. When braking with a disc brake, the brake pads move to one side, creating a collision motion. This is caused by the large gap between the brake pad and the caliper body, which can be eliminated by plating solder. However, it should be noted that the solder plating should be placed on the opposite side of the direction of travel to avoid failure under the effect of braking force. After reading the relevant introduction above, have you come up with appropriate measures to deal with the noise of disc brakes?
