Abstract

A transmission with a fluid distributing clutch hub is disclosed. The clutch hub is splined to a planetary ring gear and a second rotating element, coupling the two elements. The spline defines a number of axial fluid distribution channels that conduct fluid from an interior radial passageway beside the ring gear to exterior radial passageways over the ring gear. These axial passageways permit packaging the clutch pack directly over the ring gear without drilling holes in the hardened gear material. The axial channels may be defined by radial space between the splined components. Alternatively or additionally, some spline teeth may be omitted to define larger axial channels.

Description

Technical field [0001] The present disclosure relates to the field of transmissions for motor vehicles. More specifically, the present disclosure relates to a transmission having a clutch hub splined to a ring gear to create an axial fluid distribution passage. Background technique [0002] Many vehicles are used in a wide range of vehicle speeds (including both forward motion and reverse motion). However, most types of internal combustion engines can only operate efficiently in a narrow range of vehicle speeds. Therefore, transmissions that can efficiently transmit power at multiple gear ratios are often used. When the vehicle is at a low speed, the transmission usually operates at a high gear ratio, which doubles the engine torque to increase acceleration. When the vehicle is at high vehicle speeds, operating the transmission at a low gear ratio allows engine speeds associated with quiet, fuel-efficient cruise. [0003] Many transmissions utilize friction clutches and brakes ...
