How to adjust the displacement of rear axle of Yutong bus airbag

1. First, enlarge the positioning hole of the rear axle of the automobile to make it round, and increase the depth of the positioning hole (the bottom of the hole is flat).

2. Then prepare the central bolt for the rear axle of the automobile, the thread of the central bolt remains unchanged (even if the fit between the bolt and the central hole of the leaf spring remains unchanged), and the diameter of the bolt head increases according to the size of the positioning aperture and the requirements of the fit clearance.

Finally, there is a "buzzing" sound in the rear axle housing of the automobile, which is aggravated with the increase of load. If it is judged that the backlash of the differential gear is too large or too small, it should be adjusted. If the rear axle housing of the automobile suddenly makes a violent noise during driving, it can be considered that the gear is cracked, and the gear pair should be replaced immediately.
