The improper assembly of the leaf spring will directly affect the normal driving of the car, or damage the other parts. The following points should be paid attention to when the steel plate spring is assembled:

Check and replace the cracked plate before the assembly, remove oil and rust on the steel plate with a wire brush, coated with a layer of graphite calcium base grease.

The diameter of the center hole and the central bolt can not be more than 1.5mm, otherwise it will cause the front and back movement between the blades and affect the stability of the driving.

3. If the rivets are loose, the rivets should be re riveted. The gap between the two sides of the clamp and the steel plate should be about 2mm to ensure free extension. The iron pipe on the clip should have a certain gap between the blade and the blade.

After loading, the leaf spring should be fitted to each other, there should be no clear gap, and the arch degree should be checked. The arch degree of the left and right two pairs of steel plate springs is poor, the front steel plate shall not exceed 10mm, and the steel plate shall not exceed 20mm, otherwise the vehicle will be inclined and the control is difficult.

(5) when fastening the U bolts and nuts of Baotou Bei Ben heavy truck fittings, we should first tighten the front U bolts and nuts evenly (according to the direction of the car), then tighten the U bolts and nuts evenly.

In the middle Baotou beiben heavy truck parts leaf spring cover is provided with a rubber buffer block. In assembly, if the buffer block is found to be damaged, it should be updated, otherwise it will cause early damage to the leaf spring blade of the Baotou North running heavy card parts.
