A bearing-suspension standard assembly for a motor vehicle wheel comprises a standard ( ) with an essentially cylindrical seat ( ), and a bearing unit ( ) with a non-rotating outer race ( ) fixedly mounted in the seat ( ). A cementing material ( ) is applied at one of the axial ends of the seat ( ) so as to lock the bearing unit ( ) in the seat ( ).

Fixation of the wheel hub bearing to the suspension of a motor vehicle

In a vehicle wheel hub bearing unit the bearing forms a rotating radial flange ( ) adapted for securing to a radial flange ( ) of a disc or drum brake member and rotate fixedly therewith. The brake flange ( ) is located in the same radial plane of the bearing flange ( ) and secured directly to the peripheral portion thereof. Radial bulk of the bearing assembly is reduced and deformation of the bearing races and braking surface is avoided.

Wheel hub bearing unit

A device for locking and unlocking two mechanical members (,) coupled for rotation as a unit (,) by means of a splined coupling (,), comprises an elastic means (,) secured to the first member (,) and adapted for co-operation with the second member (,). The elastic means (,) is comprised of a bistable elastic element (,) having first (,) and second (,) alternative steady positions. The bistable elastic element is provided with hooking means (,) adapted for co-operating in the first steady position (,) with the second member (,) to keep the members (,) axially coupled, and for disengaging in the second steady (,) from the second member (,) to allow separation of the members (,) forming the coupled unit (,).

Device for locking and unlocking two mechanical members by means of a bistable elastic element

In a vehicle wheel hub bearing unit the bearing forms a rotating radial flange (11) adapted for securing to a radial flange (12) of a disc or drum brake member and rotate fixedly therewith. The brake flange (12) is located in the same radial plane as the bearing flange (11) and secured directly to the peripheral portion thereof. Radial bulk of the bearing assembly is reduced and deformation of the bearing races and braking surface is avoided.
