Service HotlineUsually, the car wheel is fixed on the axle sleeve with positioning pins and pins, and the tire hub and the sleeve are fastened on the axle with locking nuts, lock washers, and adjusting nuts. This structure can operate normally within a certain period of time when the vehicle speed is low and the vibration is small. However, when the car runs for a long time, especially when the road surface is uneven and the load changes sharply, the axle sleeve bears a great impact. Once the shear force generated is too large, the pin will break, and the nut will be loosened. Affected, the wheel and hub will be loose. If the maintenance is not timely, or the driver is inexperienced, the car will have an accident in which the tire falls off with the wheel hub. This is extremely dangerous. So people are looking for ways to prevent wheels and hubs from falling off
Shaft retaining ring (hereinafter referred to as retaining ring) is a very common part and is widely used in shaft parts. The existing solution for pressing the retaining ring is: place the retaining ring sleeve in the chamfering section or the guiding section of the shaft head, and then use an indenter whose inner hole diameter is larger than the diameter of the shaft head to press the retaining ring into the groove, and then press the retaining ring into the groove through the shaft head. The retaining ring is combined with the slot to prevent the indenter from continuing to move downward.

Nuts on the market still have certain defects. The bolts rely on multiple nuts against each other to prevent loosening. This method cannot be completely locked. The bolts are easily loosened when subjected to huge pressure and vibration, which hides potential safety hazards and has a protective effect. Bad problem, for this, we propose a nut with self-locking function
