Abstract

This utility model discloses an axle housing support shaft connection structure, specifically relating to the field of drive axle technology. Located between the wheel hub and the axle housing, it connects the two. The structure includes an axle head body, with the axle housing end extending into the axle head body. A first flange is located on the outer side of the axle housing at the end of the axle head body. A second flange, which mates with the first flange, is installed on the end of the axle head body near the axle housing. A stop seal, which mates with the axle housing, is located inside the axle head body. An inner reinforcing ring is located on the side of the stop seal facing the wheel. This utility model integrates multiple components in the axle head body, ensuring a stable connection between the axle housing and the axle head. The sealing ring and positioning stop of the stop seal provide double sealing and precise positioning. The inner and outer reinforcing rings strengthen the connection from both inside and outside. The inner support groove and dimensional gradient design optimize the fit to reduce gaps. The third flange stably connects to the wheel hub. The overall structure is compact and functionally coordinated, improving connection reliability, sealing performance, and durability.
