Relevant Knowledge
Simple judgment method of adjusting arm:
1. Check the material and mechanical strength of the adjusting arm shell and internal accessories;
2. Rotate the hexagon of the worm screw of the first-generation adjusting arm assembly continuously counterclockwise for 30 circles. During the rotation process, failure phenomena such as slipping, jumping teeth, and breaking are not allowed. After 30 circles of rotation, the locking torque of the adjusting arm must be maintained. Above 20N.m;
3. Rotate the hexagon of the worm screw of the second-generation adjusting arm assembly continuously counterclockwise for 50 circles. During the rotation process, failure phenomena such as slipping, jumping teeth, and breaking are not allowed. After 50 circles of rotation, the locking torque of the adjusting arm must be Keep above 25N.m;
Failure judgment of the front axle brake adjustment arm:
1. Appearance judgment:
Check the shell and control arm and other parts, and judge the failure of the products with cracks or breaks. Products with severe wear on the reinforcing ring and connecting sleeve shall be judged to be invalid.
If the connecting ring and the control arm can rotate relative to each other, it is determined that the product has failed. It is usually called control arm slipping. Turn the control arm clockwise until it stops, and then rotate counterclockwise. At this time, the hexagonal head of the worm cannot follow If it rotates, it is determined that the product has failed.
2. Parameter determination:
Turn the hexagonal head of the worm screw of the adjusting arm counterclockwise, and the adjusting arm with a torque less than 18N·m is judged to be invalid.
Turn the hexagonal head of the worm screw of the adjusting arm counterclockwise, the sound is discontinuous and not crisp, and the sound of "pop, pop"...is judged to be invalid.
self-adjusting arm installation
Precautions for self-adjusting arm installation:
1. The direction of the arrow on the shell should be consistent with the braking direction, that is, the direction in which the brake air chamber push rod pushes the automatic adjustment arm outward (see figure). Push the control arm toward the braking direction (the arrow on the control arm indicates the direction of push) (counterclockwise) as far as possible to the bottom. Otherwise, there will be adjustment failure and the adjustment gap is too small to cause brake lock failure.
2. The adjustment arm is divided into left and right. When installing, it must be ensured that the direction of the push rod of the air chamber is consistent with the direction of the arrow cast or engraved on the self-adjusting arm.
3. Be careful not to lose the nylon rubber sleeve of the control arm. One is to prolong its service life; the other is to ensure its adjustment accuracy.
4. The diameter of the stop gasket shall not be less than 60mm, otherwise it will lead to early failure of the stop.
5. The axial clearance of the self-adjusting arm on the camshaft should be controlled between 0.5-2mm, otherwise it will affect the adjustment accuracy and return.
