During braking, using the friction force between the lower friction plate and the brake disc, a wedge effect can be formed between the upper wedge, the lower wedge and the brake disc to generate a large braking positive pressure, thereby reducing braking force. The motor drive torque required for driving can be reduced to save energy consumption.

本发明设置有角度传感器，当摩擦片发生磨损时，ECU控制单元通过计算螺杆一的转角与正常值的差值，驱动电机二转动，推动下楔块的移动，实现对摩擦片与制动盘之间制动间隙的补偿。本发明能够保证制动间隙的恒定性，从而保障制动响应的一致性。The invention is equipped with an angle sensor.

The second motor 3 is connected with the ECU control unit 28, and is fixed on the brake caliper body 18 by the screw three 29, the second motor 3 is connected with the screw rod two 30 through the coupling two 7, and the screw rod two 30 and the adjustment wedge 31 are threaded Drive connection. One side of the adjusting wedge 31 is in contact with the lower wedge 12 , and the other side of the adjusting wedge 31 is connected with the back plate 9 through the roller 8 . The back plate 9 is connected to the brake caliper body 18 through fixing screws 6 .

在制动时，所述电机一14驱动螺杆一11转动，螺杆一11推动推杆10沿水平方向移动，进而推杆10推动上楔块15沿水平方向和竖直方向移动，消除正常制动间隙a，下摩擦片16与制动盘1接触，实现制动。在未制动时，所述滚子19相对下楔块12处于P2位置，相对上楔块15处于P3位置。在制动时，上楔块15相对下楔块12沿竖直方向移动正常制动间隙a的距离，滚子19处于P1的位置，滚子19相对上楔块15和下楔块12分别移动a/2的距离。制动结束后，电机一14反转，上楔块15和滚子19在拉伸弹簧24的作用，回到初始位置。When braking, the motor one 14 drives the screw rod one 11 to rotate, the screw rod one 11 pushes the push rod 10 to move in the horizontal direction, and then the push rod 10 pushes the upper wedge 15 to move in the horizontal direction and the vertical direction, eliminating the normal braking The gap a, the lower friction plate 16 is in contact with the brake disc 1 to realize braking. When not braking, the roller 19 is at the position P2 relative to the lower wedge 12 and is at the position P3 relative to the upper wedge 15 . During braking, the upper wedge 15 moves vertically relative to the lower wedge 12 by the distance of the normal braking gap a, the roller 19 is at the position of P1, and the roller 19 moves respectively relative to the upper wedge 15 and the lower wedge 12 a/2 distance. After braking, the motor one 14 reverses, and the upper wedge 15 and the roller 19 get back to the initial position under the action of the extension spring 24 .

当所述上摩擦片17或下摩擦片16发生磨损后，在制动时，上楔块15相对下楔块12沿竖直方向移动的距离大于正常制动间隙a，电机一14驱动螺杆一11转过的角度大于正常值。角度传感器20把螺杆一11的转角传送到ECU控制单元28；ECU控制单元28通过计算螺杆一11的转角与正常值的差值，计算出上楔块15在竖直方向需要补偿的位移。从而ECU控制单元28驱动电机二3和螺杆二30转动一定角度；调节楔块31相对螺杆二30和背板9向左移动，进而推动下楔块12、电机一14、上楔块15、下摩擦片16相对制动钳体18沿竖直方向移动相应的补偿距离，使制动间隙恢复正常值，实现间隙的自动调节。When the upper friction plate 17 or the lower friction plate 16 is worn out, when braking, the distance that the upper wedge 15 moves vertically relative to the lower wedge 12 is greater than the normal braking clearance a, and the motor one 14 drives the screw one 11 The angle turned is larger than normal. The angle sensor 20 transmits the rotation angle of the screw rod one 11 to the ECU control unit 28; the ECU control unit 28 calculates the displacement that the upper wedge 15 needs to compensate in the vertical direction by calculating the difference between the rotation angle of the screw rod one 11 and the normal value. Thereby ECU control unit 28 drives motor two 3 and screw rod two 30 to rotate certain angle; The friction plate 16 moves a corresponding compensation distance relative to the brake caliper body 18 in the vertical direction, so that the brake clearance can be restored to a normal value, and automatic adjustment of the clearance is realized.
