HDB’s first wheel unit was introduced more than 15 years ago. Since then, an
increasing number of functions have been incorporated into hub units. Today, these
integrated, sealed, pre-greased and preset wheel bearing hub units have proven
themselves over millions of road miles. Wheel hubs may also transmit driveline
torque, provide a mounting point for the brake disc and wheel, and serve as a
structural member of the suspension.
Ever since the first wheel speed signal system was introduced to now G3 wheel hub bearing 40202-ED000, HDB's attention has been focused on optimizing the integration of sensor functions in hub bearing units.
Due to the position and mechanical precision of hub units, they are a perfect point
for monitoring vehicle speed. For reasons of both safety and driving comfort, more
and more vehicles are being equipped with speed sensing devices (primarily sensors
that provide the signal system with the wheel speed information). The optimum wheel
speed sensor solution is unique for each individual application.
Depending on vehicle requirements, the sensor can be either non-integrated,
which is the case in the most simple application; or an
integrated design, which improves reliability, saves weight,
and facilitates assembly.
