Hub/wheel bearing unit
The newly developed wheel bearing generation
is used on the rear axle of front-wheel-drive
vehicles. The twin-tracked ball bearing has a
stationary outer race which is bolted to the rear
axle mounting plate.
The bearing inner race serves as the carrier for
the brake disc and wheel. This design eliminates
the need for an axle pivot.
The ABS speed sensor is inserted into the wheel
bearing and secured with a clip to prevent it
from falling out.
The advantages of the new wheel bearing
generation are as follows:
l Minimal wear due to improved sealing.
l The rotor is protected by the inserted
speed sensor and cannot be damaged by
external influences.
l The wheel bearing does not have to be
adjusted any longer because the bearing
preload is predetermined by its design.
