POWER TAKE-OFF UNIT (PTO) WITH INTEGRAL SHIFTER

摘要

Provided is a power transfer unit, such as a power take-off unit including an input shaft coupled to an input gear for common rotation and axially movable relative to the input gear for engaging a coupling at a first end of the shaft with a drive component, a chamber formed between the input shaft and input gear, and a piston axially movable in the chamber, whereby the piston rotates with the input shaft. Due to the rotation of the piston with the input shaft, a power take-off unit is provided without the need for components to separate the piston from the input shaft.

1. A power transfer unit including:
a housing; an input gear rotationally supported in the housing; an input shaft coupled to the input gear for common rotation, the input shaft being axially movable relative to the input gear for engaging a coupling at a first end of the shaft with a drive component; a chamber formed between the input shaft and input gear; and a piston axially movable in the chamber and sealed to the input shaft and input gear, whereby the piston rotates with the input shaft.
