WHEEL BEARING ASSEMBLY, CAPABLE OF IMPROVING DURABILITY BY UNIFORMLY APPLYING STRESS TO A DRIVER

摘要

PURPOSE: A wheel bearing assembly is provided to improve durability by resolving non-uniform stress by asymmetrically forming a crowning.;CONSTITUTION: A wheel bearing assembly comprises a hub(10), an inner wheel(20), an outer wheel(30), and drivers(40,41). The inner wheel is mounted on the stepped part(12) of the hub. The outer wheel is equipped in the outside of the inner wheel and the hub. A driver is equipped between the hub and the outer wheel, and between the inner and outer wheels. The hub or the inner wheel is formed with an inner orbit part for being in touch with the driver. The inner orbit part is formed with an inner crowning into an asymmetrical sectional shape.;COPYRIGHT KIPO 2013
