Please pay attention to the failure causes and maintenance methods of the disc brake.

The common faults of disc brake include air resistance, insufficient braking force and noise during braking. Here is a brief introduction to the causes and maintenance methods of the faults.

1、 Air resistance

The heating part of the disc brake is concentrated on a very narrow brake pad, and its unit pressure is larger than that of the drum brake. The brake pad is in direct contact with the piston of the caliper body, so the heat during braking is easily transferred to the brake fluid. In this way, the disc brake is prone to air lock. However, if corresponding measures are taken, the occurrence of air resistance can also be prevented.

1. Prevent the boiling point of brake fluid from decreasing

Vegetable oil type brake fluid cannot meet the use requirements of disc brake, so synthetic brake fluid with high boiling point must be used. However, synthetic brake fluid has water absorption properties. Under certain usage conditions, the boiling point decreases rapidly. To prevent a significant decrease in the boiling point of brake fluid, the following measures are commonly adopted:

(1) Regularly replace the brake fluid. 3 months or 5000km in summer; After 6 months of winter or 1000 kilometers of driving, the brake fluid will be updated soon.

(2) Brake fluids with different properties cannot be interchanged or mixed.

(3) Store brake fluid tightly. Automobile maintenance network

To increase the temperature of the brake fluid, it is necessary to ensure that the piston can flexibly and automatically return to its original position to avoid slipping or biting of the brake due to rust or jamming. When the brake pads are excessively worn, the heat transmitted to the brake fluid will also rapidly increase. Therefore, worn brake pads should be replaced in a timely manner.

2、 Insufficient braking force

When the braking force of the disc brake is insufficient, the following methods can be used to solve the problem:

1. Change the brake pad material

A slightly softer brake pad material can be used to improve the friction coefficient and increase the braking force.

2. Remove foreign objects from the debris removal groove of the brake pad

If the debris discharge groove of the brake pad is covered by foreign objects, the effect of dust discharge and water scraping will be lost during braking, resulting in a decrease in braking force.

3、 Noise during braking

When braking, if there is a "squeaking, squeaking" noise, the following methods can be used to eliminate it:

1. Add an anti noise pad between the brake caliper piston and the brake lining to create a tilt on the piston. This ensures flexible contact between the brake pads and brake discs during braking, ensuring that there is no abnormal noise in the brake pads under normal wear and tear conditions.

2. Choose a brake pad material that is softer and less dense.

3. When braking, the brake pads may move to one side and there may be a knocking sound. This is due to the excessive gap between the brake pad and the caliper body, which can be eliminated by electroplating solder. However, it should be noted that the solder should be coated on the side opposite to the direction of travel to prevent failure under the action of braking force.

4、 Damaged front wheel bearings

The brake caliper body is generally installed behind the steering knuckle, which can relatively reduce the load on the front wheel bearings during braking. However, some models install the clamp body in front of the axle, which increases the synthetic load on the front wheel bearings and can easily cause premature damage to the front wheel bearings. Therefore, for wheels with this structure, timely adjustment and maintenance should be carried out.

The purpose and characteristics of the power loss brake

The purpose and characteristics of the power loss brake, brake factory 15838971872, welcome friends to cooperate and consult with the factory.

The purpose of the power-off brake: The DHD series brakes are friction disc brakes (hereinafter referred to as brakes) that apply spring pressure during electromagnetic disengagement (release) and power-off. It can be paired with electric power to become a new type of braking motor, and can also be used in mechanical transmission systems to achieve fast parking and accurate positioning. It can be used in situations such as safe (anti risk) braking in case of power failure. This type of brake has the advantages of simple structure, wide adaptability, low noise, and reliable braking, and is widely used in various mechanical transmission devices. It is an ideal actuator in industrial modernization. The automation of production technology requires ultra-thin power-off brakes (safety brakes) to meet the needs of various machinery such as robots and motors for different purposes with their excellent characteristics.

Structural characteristics of the power loss brake:

1. Although the axial size of the compact and power-off brake is small, the braking torque is sufficient.

2. The quick response and power loss brake uses a spring device to form braking torque, and the spring reset time is the braking response time.

3. Long service life, power loss braking adopts new friction materials, which determine the performance of high service life.

The power loss brake can operate reliably under the following conditions:

1. The relative humidity of the surrounding air shall not exceed 85% (20 ± 5 ℃).

2. There is no gas or dust in the surrounding medium that is sufficient to corrode metals and damage insulation.

3. The brake is surrounded by Class B insulation, with voltage fluctuations not exceeding+5% and -15% of the rated voltage, and its working mode is continuous working.

4. During installation, ensure the accuracy of the fit between the transmission shaft and the brake.

5. The brake disc of the brake must be used without oil stains.
