Description

Technical Field

[0001] The utility model relates to the technical field of nut adjusting tooling, and particularly relates to a nut adjusting tooling. Background Art

[0002] The axle is a key component in the vehicle suspension system, connecting the wheels to the body, supporting the vehicle weight, absorbing road shocks, and ensuring wheel positioning and stability. The axle can be divided into the front axle and the rear axle. The front axle is mainly responsible for steering and support, while the rear axle is mainly responsible for load bearing and power transmission. The nut of the axle main reducer is usually located in the rear axle system of the vehicle, used to adjust the pre-tightening force of the main reducer, ensure that the gear clearance of the main reducer is within the correct range, so as to optimize the performance and durability of the transmission system.

[0003] When repairing the axle, it is necessary to first adjust the differential inside the main reducer, including adjusting the meshing impression and meshing clearance of the main / pinion gears. During the actual repair process, it is necessary to first adjust the pre-tightening degree of the bearing, then adjust the meshing impression, and finally adjust the meshing clearance. Since it is necessary to ensure a larger meshing surface between the main gear and the pinion gear to avoid damage. Therefore, the pre-tightening degree adjustment of the pinion gear needs to be adjusted by adjusting the nut, that is, by squeezing the outer side of the bearing through the adjusting nut at the transition block, and then adjusting the slight movement of the left and right positions of the pinion gear. And for the adjustment of the pinion gear, it is necessary to first tighten the adjusting gears on the left and right transition blocks of the main reducer so that the left and right adjusting nuts are firmly fixed to the pinion gear; after the pinion gear is fixed, it is necessary to adjust the whole to maximize its meshing surface with the main gear. The existing operation method requires manual holding of the tightening tool to adjust one by one manually, and the operation process is relatively cumbersome and the efficiency is low.
