ASSEMBLY OF OIL GUIDE AND THRUST WASHER FOR AUTOTRANSMISSION

摘要

An oil guide of an automatic transmission and a thrust washer assembly are provided to prevent the oil from being accumulated at a specific region by uniformly supplying the oil to a clutch and a pinion shaft. A thrust washer(100) includes plural oil grooves, which are formed along a circumference of the thrust washer. The oil groove decreases a friction between the oil groove and a balance piston by using an axial vibration of a planetary gear carrier and lubricating oil from an input shaft. Plural oil guides(200) are spaced from one another along a periphery of the thrust washer, such that the lubricating oil from the thrust washer is delivered to the pinion shaft. A first oil groove(110') is formed at an implementation direction of the oil guide, such that the lubricating oil is supplied to the pinion shaft. A second oil groove(110'') is formed away from the implementation direction of the oil guide, such that the lubricating oil is supplied to an overdrive clutch(500).
