Jiaozuo brake

The repair of the SBD safety brake hydraulic cylinder body (cylinder barrel) requires inspection of the size and tolerance of the hydraulic cylinder hole after disassembly (usually H8 or H9, H7 for piston ring sealing, and H6 for gap sealing). The surface roughness of the inner hole (Ra0.8-0.2). The geometric accuracy of the cylinder hole (reference value is that the roundness and cylindricity error should be less than 1/2-1/3 of the diameter size difference). The straightness error of the cylinder hole axis (should not be greater than 0.03mm for a length of 500mm), and the verticality error of the cylinder end facing the axis (should not be greater than 0.04mm for a diameter of 100m).

Check the axis of the hole in the SBD safety brake hydraulic cylinder, the position error (reference value is 0.03mm) and verticality error (not greater than 0.1mm on a length of 10mn) of the cylinder axis, and the position error and verticality error (not greater than 0.1mm on a length of 100mm) of the ST3SH safety brake hydraulic cylinder axis. When assembling the ST3SH safety brake hydraulic cylinder, be careful to prevent the sealing lip from being cut. The guide sleeve is inserted into the piston rod to prevent the sealing lip from being cut. After disassembling the hydraulic cylinder, the following key parts and important positions should be inspected to determine which parts can be reused and which need to be repaired before reuse, What should be replaced? If the brake clearance between the two brake pads of the disc brake is too large, loosen the fastening screw of the camshaft bracket, and adjust it using the following method. When rotating the support pin directly, use the brake shoe to jack the camshaft to make it reach the appropriate position. Step on the brake pedal, the cam opens, and use the reaction force of the brake shoe to make the camshaft reach the appropriate position.

Adjust when braking for deviation. When the front wheel brake deviates, it can be adjusted by increasing the brake clearance on the other side of the deviation (or reducing the brake clearance on the deviation side). This can relatively increase the stroke of the push rod on the other side of the deviation, increase the effective area of the leather film, and increase the braking force, thereby eliminating the phenomenon of deviation. When increasing the braking clearance, it will cause a decrease in braking force. Therefore, this method can only be used when the effective area of the film increases the braking force, exceeding the decrease in braking force caused by the increase in braking clearance. Therefore, this method is not applicable when the difference between the brake clearances of the left and right disc brakes is too large. Measurement of brake pad thickness and brake clearance Brake clearance and brake shoe brake pad thickness are measured through the inspection hole on the disc brake. When checking the brake clearance, support the axle and suspend the wheels. Use a feeler gauge to measure the clearance between the brake shoes and the brake drum.
