摘要

#CMT# #/CMT# The unit (1) has an inner ring (4) axially held on a hub (5) by a collar. The collar comprises a gearing (7) in an intervention with an appropriate counter teeth at a joint component (9). The gearing and the counter teeth are braced against each other by a screwing element (17). A screw thread (12) is supported into the hub at the joint component over a head (18). The head is axially pre-tensioned over a rotation axis of an inclined surface. A sealing ring is radially introduced between a shaft of the screw element and an inside wall (23) of the hub through a hole. #CMT#USE : #/CMT# Wheel bearing joint unit for a motor car. #CMT#ADVANTAGE : #/CMT# The sealing ring is radially introduced between the shaft of the screw element and the inside wall of the hub through the hole, so that the wheel can be easily disassembled in an energy-saving, simple and inexpensive manner, and avoids the needs of dragging power for driving the wheel. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a wheel bearing joint unit. 1 : Wheel bearing joint unit 4 : Inner ring 5 : Hub 7 : Gearing 9 : Joint component 12 : Screw thread 17 : Screwing element 18 : Head 23 : Inside wall.
