COUPLING STRUCTURE OF THE HUB BEARING OF A VEHICLE WHEEL TO A CONSTANT SPEED JOINT, CAPABLE OF EASILY ASSEMBLING AND DISMANTLING A HUB BEARING UNIT BEFORE AND AFTER THE CONSTANT SPEED JOINT

摘要

PURPOSE: A coupling structure of the hub bearing of a vehicle wheel to a constant speed joint is provided to optimize closed sealing operation in the interface area between a constant speed joint and a hub bearing unit and to prevent water from approaching the coupling structure spline-formed between the joint and the hub bearing unit.;CONSTITUTION: A coupling structure of the hub bearing of a vehicle wheel to a constant speed joint comprises a tube shape protrusion unit(31), a hub bearing unit, and a lid member(40). The tube shape protrusion unit is inserted into a driving ring(18). The hub bearing unit includes a hub(10) to which the driving ring is fixed. The lid member is held in the cavity of a bell member. The lid member is contiguous to the radial shoulder formed in the bell member. The hub is detachably fixed by the lid member and a fixing unit(43). The fixing unit makes the lid member connect detachably to the hub.;COPYRIGHT KIPO 2010
