AI Technical Summary

Technical Problem

In the prior art, the sealing and lubrication problem of gear assemblies is difficult to solve when the angle changes are large, especially in the "Tatra" type drive axle, where the sealing and lubrication performance of the gear assembly is insufficient during the angle change between the output half shaft and the input shaft.

Method used

The system employs a circumferentially foldable gear-shaped soft oil pack, comprising the oil pack body, a first rigid oil seal, and a second rigid oil seal. Designed in the shape of a gear housing, it is made of steel wire and soft, oil-resistant, and wear-resistant materials. The V-shaped movable opening closes after installation, providing a flexible seal. The power output port can circumferentially swing to ensure sealing. The drive bridge includes two bridge arm housings and the gear-shaped soft oil pack. The power output shaft swings synchronously with the bridge arm housings to ensure lubrication.

Benefits of technology

It achieves large-angle swing of the power output shaft, exceeding the limit angle of the "Tatra" type drive axle, ensuring the sealing and lubrication performance of the gear assembly during large-angle changes, and improving off-road performance and safety.
