Abstract

Abstract Wheel bearing with a built-in homokinetic coupling. The wheel bearing comprises a generally annular inner part, an outer race and two rows of rolling elements located between the outside running surfaces formed on the outer race and the inside running surfaces applied to the inner part. The outer race is equipped with a radially extending flange for the attachment of the bearing. The annular inner part is equipped with a radially extending flange to which the hub of a wheel can be attached. The inner part forms at the same time one unit with the outer ring of the homokinetic coupling. The flange of the inner part is extended with a brake element which forms the part to be braked of a braking mechanism so that the inner part of the bearing, the carrier flange for the wheel, the brake element and the outer ring of the homokinetic coupling form one homogeneous unit. The inner raceway surfaces for the rolling elements are treated to a high grade bearing material and the inner part has an axial stub directed away from the homokinetic coupling and extending beyond the attachment flange to define a guide means for the hub of the wheel.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 233 words
Wheel bearing with a built-in homokinetic coupling, including a generally annular inner part, an outer race and two rows of rolling elements located between the outside running surfaces formed on the outer race and the inside running surfaces applied to the inner part, whereby the outer race is equipped with a radially extending flange for the attachment of the bearing, and the annular inner part is equipped with a radially extending flange to which the hub of a wheel can be attached, and whereby this inner part forms at the same time one unit with the outer ring of the homokinetic coupling characterized by the fact that the flange (13, 13') of the inner part (1, 1') is extended with a brake element (17, 17') which forms the part to be braked of a braking mechanism (18, 18'), so that the inner part (1, 1') of the bearing, the carrier flange (113, 13') for the wheel, the brake element (17, 17') and the outer ring (10, 10') of the homokinetic coupling (9, 9') form one homogeneous unit, the inner raceway surfaces for the rolling elements being treated to form a high grade bearing material and said inner part having an axial stub (21, 21') directed away from the homokinetic coupling (9, 9') and extending beyond the attachment flange (13, 13') to define a guide means for the hub (16, 16') of the wheel.
