Description

Hub reduction gear shell welding structure

Technical Field

The utility model relates to a wheel reduction gear shell processing technology field specifically is a wheel reduction gear shell welded structure.

Background

The wheel-side reducer is used for improving the driving force of the automobile so as to meet or correct the matching of the driving force of the whole transmission system, and the engine ignition transmits the power to the main reducers of the front axle and the rear axle through the clutch, the speed changer and the transfer case, and then the power is transmitted to the wheel-side reducer and wheels from the output end of the main reducer so as to drive the automobile to run. In the process, the working principle of the hub reduction gear is that the rotating speed and the torque transmitted by the main reduction gear are reduced and torque-increased through the hub reduction gear, and then transmitted to the wheels, so that the wheels generate larger driving force under the reaction of ground adhesion, the hub reduction gear is connected with a vehicle body through a hub reduction gear shell, and the hub reduction gear shell is easy to deform and needs to be welded at the joint of the hub reduction gear shell because the strength of the existing hub reduction gear shell is insufficient.

Common round of limit speed reducer shell welded structure, common round of limit speed reducer shell is fixed through screw and bolt, nevertheless because the part position of round of limit speed reducer shell can take place deformation when welding, if take place deformation in screw and bolt department, the internal thread that can lead to the screw takes place to split or the phenomenon of distortion to the later stage that influences inside round of limit speed reducer shell can't be opened, takes out inside round of limit speed reducer, proposes a round of limit speed reducer shell welded structure for this reason.
