What does flywheel throwing failure mean?

[XavierLee]

Flywheel throwing failure refers to a mechanical accident where the wheel, along with the hub and brake drum, automatically detaches from the vehicle while driving. The causes of this failure are as follows: Poor connection between the hub and axle: The front wheel hub of a car is installed on the steering knuckle with two sets of reverse-mounted radial thrust bearings. The bearing clearance is adjusted with the inner nut of the steering knuckle, and the outer part is secured with a locking nut. Improper connection of the stop device and locking device can lead to flywheel throwing failure. Radial thrust bearing failure: Improper adjustment and use of radial thrust bearings can cause issues. If the bearing clearance is too small, the bearings may burn out. Conversely, if the clearance is too large, additional impact forces during driving can cause thread failure, also resulting in flywheel throwing failure.
