Braking Process and Characteristics of Brake Disc
    The Brake Disc has its own force. When the two friction plate assembly in the short half-axis driven by counterclockwise rotation. The friction between the friction surface caused by friction, so that the brake pressure plate also followed counterclockwise rotation, but because the inner Brake Disc earrings by the Brake Disc shell on the shoulder restrictions, can not be rotated, and outside Brake pressure plate in the friction torque, will be relative to the inner Brake Disc to continue counterclockwise rotation, which helps the ball continue to move the two Brake Discs to both sides of the process, the process put The role of self-power. When the friction plate assembly is rotated clockwise, the outer ring of the Brake Disc is restricted by the shoulder on the Brake Disc housing, and its energization and braking procedures are similar to those described above. So whether the tractor forward, or back, Brake Disc brake with their own role when the force.
    Brake Discs are small in size, compact in structure, easy to operate, easy to seal, friction lining wear more uniform, long life, no need to adjust the gap, the braking effect is good, with the advantages of self-boost force. The main drawback is that the brake is not smooth enough, individual parts (such as brake pressure ball slot) processing more complex.
  Brake Disc is a common product in a large category, its technical performance and stability, the following to introduce its technical parameters:
    (1) the diameter of the Brake Disc D: Brake Disc diameter D should be taken as much as possible to increase the effective radius of the Brake Disc to reduce the clamping force of the clamp, reducing the unit pressure and operating temperature The The diameter of the Brake Disc is usually chosen to be 70% to 79% of the diameter of the rim, as limited by the diameter of the rim. The total mass of more than 2t of the car should take the upper limit.
    (2) Brake Disc thickness h: Brake Disc thickness h on the Brake Disc quality and work temperature impact. In order to make the quality smaller, the Brake Disc thickness should be smaller; in order to reduce the temperature rise, the Brake Disc thickness should take some. The Brake Disc can be made solid, or for cooling, ventilation needs to cast the ventilation duct in the middle of the Brake Disc. General solid Brake Disc thickness can be taken as 10 ~ 20mm, ventilated Brake Disc thickness of 20 ~ 50mm, using more is 20 ~ 30mm.
    (3) friction outside the radius of the liner and the radius: the recommended friction outside the radius of the ruler and the radius of the ratio of not more than 1.5. If the ratio is too large, the outer edge of the liner and the inner peripheral speed of the difference between the more, uneven wear, contact area decreases, and ultimately will lead to large changes in braking torque.
    (4) Brake pad work area A When determining the working area A of the Brake Disc brake pad, it is recommended to use the vehicle mass in the range of 1.6 to 3.5 kg / cm2 according to the vehicle mass occupied by the brake pad per unit area.
The specific procedures and requirements for installing the frequency converter on the Brake Disc.
Motor selection with Brake Discs Basic requirements for supporting the drive The motor with the Brake Disc selects the frequency converter and must be a regenerative brake signal processing unit inside it or has a regenerative brake signal as an optional part Processing unit.
At the same time, in order to motor positioning, emergency stop and stop when the maintenance should generally be used with mechanical Brake Disc motor.
Frequency control system on the Brake Disc power supply connection requirements:
Brake Disc power must be connected to the input of the inverter, because the output voltage of the inverter is low voltage at low speed, so the suction force of the electromagnet will be weakened and the Brake Disc will be released. of.
Therefore, the voltage of the Brake Disc can not be the same as that of the motor.
