How to avoid mechanical failure of Brake Disc
Brake Disc are commonly used in mechanical equipment, braking equipment, in some power equipment will also use it, such as: cars, cranes and so on. Take the bike, the new car riding will be more comfortable, but with the increase in the number of years, there will be brake failure, or hold the gate of the situation. Imagine that the brake can not be dangerous for the bike, then for the faster speed of the car or mechanical equipment, the risk has increased a lot. Therefore, to find out the reasons for the disc brake failure, to avoid accidents is what we need to do. First of all, we have to understand the next type of brake failure several types: 1, when the power to stop, the gate automatically slow down or hook quickly fall, disc brake serious failure; 2, power, Brake Disc brake Loose brake or delay loose; 3, disc brake working when the electromagnetic circuit when the vibration and noise. The cause of disc brake failure is divided into mechanical and electrical aspects and other reasons. Mechanical problems are: Brake Disc do not move after the power or do not open the gate, Brake Disc hold the gate, brake brake is not working (slow braking), brake pads wear or even burn, vibration sound and other failures The
The specific procedure and requirements for installing the frequency converter on the disc brake.
The basic requirements for the selection of the drive with the disc brake The selection of the inverter with the disc brake must be either the regenerative brake signal processing unit or the regenerative brake signal processing unit The At the same time, in order to motor positioning, emergency stop and stop when the maintenance should generally be used with mechanical disc brake motor.
Frequency control system on the disc brake power supply connection requirements: disc brake power must be connected to the input of the inverter, because the inverter output voltage at low speed when the low voltage, so the electromagnet suction will weaken, The brakes will be released, which is not allowed. Therefore, the voltage of the disc brake can not be the same as that of the motor.
What is the problem with the working principle of Brake Disc, first of all we have to understand its braking system. So how does the brake system of the Brake Disc work and play a role?
    A simple hydraulic brake system can be used to illustrate the working principle of the braking system. A metal brake drum with a round face as the working surface is fixed to the wheel hub and rotates with the wheel.
    On a fixed brake floor, there are two support pins that support the lower ends of the two curved brake shoes.
    The outer surface of the brake shoe is fitted with a friction plate. The Brake Disc is also provided with a hydraulic brake wheel cylinder connected to the hydraulic brake master cylinder mounted on the frame. The piston 3 in the master cylinder can be manipulated by the driver through the brake pedal mechanism.
    When the driver depresses the brake pedal so that the piston compresses the brake fluid, the wheel cylinder presses the brake shoe against the brake drum under the action of the hydraulic pressure, causing the brake drum to reduce the rotational speed or remain stationary.
    The resistance torque that must be applied to stop or decelerate the mechanical running parts is called the braking torque. Braking torque is the basis for the design and selection of Brake Disc, whose size is determined by the type and work requirements of the machine.
    The performance of the friction material (brake) used on the Brake Disc directly affects the braking process, and the main factors affecting its performance are the operating temperature and the temperature rise speed. Friction materials should have high and stable friction coefficient and good wear resistance.
    Friction materials are metal and nonmetallic. The former commonly used cast iron, steel, bronze and powder metallurgy friction materials, the latter are leather, rubber, wood and asbestos.
