REDUCER OF AN ELECTRIC POWER ASSISTING STEERING SYSTEM, CAPABLE OF PROVIDING FRESH DRIVING ENVIRONMENT BY DECREASING RATTLE NOISE CAUSED BY THE INCREASE OF BACK LASH DUE TO THE ABRASION OF A WORM AND A WORM WHEEL

摘要

PURPOSE: A reducer of an electric power assisting steering system is provided to reduce resonant sound by absorbing vibration from a worm axis with a damper.;CONSTITUTION: A reducer of an electric power assisting steering system comprises a gear housing(260), a worm axis(254), and a worm wheel(156). The gear housing is coupled to a motor(146) providing the steering assisting power. The worm axis is connected to the gear housing, and moves together with the axis of the motor and comprises a worm(152) on its outer circumference. The worm wheel is meshed with the worm to drive a steering axis(106). A hollow(315) is formed in the worm axis and a damper(310) is coupled to the hollow.;COPYRIGHT KIPO 2010
