Abstract

The present invention discloses a shaft assembly for conveying fluid in a transmission of a vehicle. The shaft assembly includes an input member rotatable about a longitudinal axis. The input member defines a chamber along the longitudinal axis. The shaft assembly further includes a shaft that rotates about the longitudinal axis and extends to a first end facing the input member. The shaft and input member are spaced apart along the longitudinal axis to define a gap therebetween. The shaft assembly also includes a cover attached to the shaft, wherein the cover extends through the gap into the cavity of the input member. The cover defines an aperture in fluid communication with the chamber for communicating fluid from the shaft to the chamber of the input member.

Description

technical field [0001] The invention relates to a gearbox for a vehicle including an engine, wherein the gearbox is configured to convey fluid, and to a shaft assembly for conveying fluid in the gearbox. Background technique [0002] There are various types of gearboxes used in vehicles. One type of transmission may include an input shaft connected to a vehicle engine. The input shaft is rotatable about the central axis. The output shaft cooperates with the input shaft and is also rotatable about the central axis. Specifically, the input shaft is arranged in the output shaft, wherein a seal is arranged between the input and output shafts for preventing fluid from leaking therebetween. As the shaft rotates, the seal can create friction between the input and output shafts, which can cause loss of rotation of the input and output shafts. Contents of the invention [0003] The present invention provides a shaft assembly for conveying fluid in a transmission of a vehicle. ...
