Low flat semi - trailer oblique direction is what is going on. Low flat semi trailer is a kind of commonly used semi trailer, its use is very common, and the effect is good, but low flat semi trailer driving also need to pay attention to a lot of problems, the following is about low flat semi trailer oblique direction is what is going on.
1, the vehicle skew is mainly because the distance between the traction pin center and the corresponding points on both sides of the first axle is not equal (three points are not isosceles triangle), if out of tolerance may cause abnormal tire wear (zigzag phenomenon).
2. Detection and adjustment method
1) Park the vehicle on a level road surface without braking.
2) Take points on the inner surface of the front wheel hub of the front axle, and take points on the left and right sides with symmetrical positions.
3) Take the traction pin center as the benchmark, measure the distance to the above two points, the requirement is "l1-L2I 3mm. If out of tolerance, adjust the front axle live pull rod until it meets the deviation requirement.
4) Before measurement, check the measured value at corresponding points of rear axle hub, requiring 2mm of old 181-821. If it is out of tolerance, adjust the rear shaft pull rod to make the front and rear shafts parallel until the deviation meets the requirements.
5) Tighten the fastening bolts on the front and rear drawrods.
6) After adjustment, drive about one kilometer and stop in place without braking, and check the above dimensions. If there is no change, the adjustment will be successful.
7) The adjustment process should make the pull rod in working state, that is, a rotation of the pull rod, the bearing of the car, the adjustment of the pull rod is normal.
