The axle of a vehicle consist of the wheels, the
wheel hubs, the
wheel bearings and various
nuts,
studs and screws.
There are two types of wheel bearings: round or cone-shaped. The
wheel bearing is fitted into the wheel hubs. The car’s wheels are fixed to the
wheel hubs as well. To fix the wheel securely to the wheel hubs, each wheel has several bores in which the wheel studs are fitted.
