What is an active disc finished component?

The active disc finished part brake is also called a disc brake part, named for its shape. The brake disc is made of alloy steel and is fixed to the wheel when the wheel rotates. The contact of the active disc component occurs between the fixed part of the car and one or more ends of the brake, so what is an active disc finished component?

What is an active disc finished component?

The contact material only covers a small part of the disc brake, known as the caliper disc brake. The disc brake with all working surfaces of the contact material is called an integral brake part. Modern cars widely use single disc single calibration disc brakes. Only a few large tonnage special dump trucks use single disc, three calipers, double calibration, single standard fixed disc brake parts, and the variety is complete. Do you know the advantages and disadvantages of the active disc components used in most domestic cars?

1. The braking torque is independent of the front and rear of the car.

2. Good thermal stability. Because the size of the brake contact film is not long, the working surface area is only 12% to 6% of the brake disc area, so the heat dissipation is good.

3. The thermal expansion of the active disc component does not cause a loss of brake pedal travel like the thermal expansion of the brake drum, which also simplifies the design of the automatic gap adjustment device.

4. Good water stability. Due to the pressure of the disc brake unit, it is easy to lose water. Under the action of centrifugal force, water can be easily expelled. With the wiping of the disc brake pads, normal braking performance can be restored after more than ten brake applications.

5. The valve flap lining is left, and the valve flap is easy to replace. The structure is simpler, and maintenance is more convenient.

6. The active disc finished part and contact film are smaller (0.05-0.15mm), which shortens the working time of the cylinder piston and increases the power ratio of the braking transmission.

What are the preventive measures for active disc finished components?

1. The manufacturing requirements for the active disc are high, the contact film wears severely, and the cost is expensive.

2. Due to the small contact area of the contact film, the relative contact of the working surface is also small. It requires higher brake fluid pressure. The vehicle must use a device with a booster, generally using a servo device.

3. Brake failure. The two contact points on the flower key can slide back and forth, which is the rotating part of the brake shell. During braking, the vehicle can stop in a short time. In addition, the angle of the ball groove on the disc cannot be infinitely large, and the braking is not smooth.

The above is the relevant knowledge about what an active disc finished component is that I have organized for you. Currently, active disc components have been widely used in domestic cars, and most disc brakes are used on all wheels. A few are used as front wheel brakes, used together with rear drum brakes. Currently, new models and types have gradually adopted disc brakes.
