When the preload adjustment is completed, the edge of the side bearings are caulked in the caulking grooves to fix the side bearings so that the preload adjustment state of the side bearings is not released or changed And more particularly, to a preload adjustment device and a method of installing a side bearing of a vehicle carrier assembly.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a preload adjustment device and a preload prevention device for a side bearing provided in a vehicle carrier assembly, and a mounting method using the preload adjustment and release prevention device.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a preload adjusting device and an unloading preventing device for a side bearing provided in a vehicle carrier assembly, and a mounting method using the same. More particularly, The present invention relates to a device for preventing and adjusting a preload of a side bearing provided in a carrier assembly and a mounting method using the same.

The side bearings are generally mounted on both sides of the vehicle carrier assembly, but preferential preload adjustment must be made.

To this end, when the side bearings are normally assembled into the carrier case of the carrier assembly, an adjust screw, which is arranged at regular intervals along the inner circumferential surface, is screwed into the carrier case to align the preload of the side bearings.

Thereafter, the operator adjusts the position of the plate lock for preventing preload unlocking and adjusts the position by loosening or tightening the adjuster screw in a slightly positive or reverse direction to match the adjacent adjustment.

Subsequently, a plate lock is disposed between the adjusters, and a plate and a bolt serving as a washer are added to fix the plate lock to the carrier case.

At this time, the plate is bent to prevent the bolt from being released.

However, in such a conventional method, many parts such as a screw, a plate lock, a plate, and a bold are required to fix the side bearings to prevent loosening while the side bearings are pre-adjusted to the carrier case. There is an inevitable increase in working time and raw material cost.

Particularly, such a conventional method is faced with a fatal problem in which a preload is changed by adjusting the position of the adjuster screw by slightly loosening or tightening the adjuster screw in the forward or reverse direction in order to fit the gap therebetween.

Therefore, in consideration of this point, development of a device for precisely maintaining the preload adjustment state of the side bearings without being released or changed is urgently required.
