AI Technical Summary
Technical Problem
There is a matching gap problem with the assembly of existing wheel hubs and end caps, which leads to rust on the end surface of the wheel hub installation, and adding bolts or painting processes will increase production and assembly costs.
Method used
By designing an end cap structure including a slope surface, a jaw member and a tightening ring, the hook part of the jaw member is snapped into the groove ring of the hub, and the tightening ring tightens the hook part to ensure that the end cap and the hub are sealed.
Benefits of technology
The sealing fit between the hub and the end cover is achieved, avoiding matching gaps and rust problems, simplifying the assembly process, and reducing production and assembly costs.

Abstract
The utility model relates to the technical field of automobile parts, and provides an end cover and a hub assembly. The end cover is used for a hub of the vehicle and comprises a matching end face and a slope face located on the inner side of the matching end face. The multiple clamping jaw pieces are arranged on the slope face at intervals, the clamping jaw pieces are provided with claw parts protruding in the radial direction, and grooves are formed in the back faces of the claw parts; and the tight supporting ring is tightly supported in the grooves of the plurality of clamping jaw pieces. When the end cover provided by the utility model is assembled with the hub, the hook claw part is clamped into the groove ring on the inner wall of the shaft hole of the hub, so that the end cover is hung on the hub; the clamping jaw piece is arranged on the slope surface capable of weakening the plastic shrinkage deformation phenomenon and can be stably clamped in the groove ring of the hub; in addition, through the grooves formed in the back faces of the hook claw parts and the tight supporting rings tightly supported in the grooves of the multiple clamping claw pieces, when the hook claw parts are clamped into the groove rings of the hub, the tight supporting rings tightly press the hook claw parts to the groove rings, the matching end face of the end cover is attached to the installation end face of the hub, and it is ensured that the end cover is in sealed fit with the hub.
