发明名称 Radial bearing for an automatic transmission
摘要 In an automatic transmission an input part (3a) of a hydrodynamic torque converter is connected by way of a hollow shaft (3) to a pump impeller (2a) of an input pump. The said hollow shaft (3) is supported in the pump or transmission housing (2) by means of a needle roller bearing (1). Since an axial displacement of the hollow shaft (3) relative to an inner race (8) of the needle roller bearing (1) can occur due to a pressure rise in the converter housing and due to temperature changes, the inner race (8) is provided on its inner circumferential surface with an antiwear coating (16). <IMAGE>
