Appl. No.:

16/410754

Inventors:

Chad Timothy Leichliter - Quakertown PA, US
Steven William Butcher - Collegeville PA, US

International Classification:

F16H 57/04
F16H 57/032

Abstract:

A Power Transfer Unit (PTU) has a housing with at least one side having an outer surface. One or more standoffs are provided at the at least one side of the housing and extend outward from the outer surface of the housing. A thermal deflector formed as a flat plate is attached to the standoffs at a predetermined distance from the outer surface of the housing. The flat plate deflects heat from nearby components, such as the catalytic converter and/or exhaust pipe, away from the PTU.

International Classification:

F16H 63/32

Abstract:

The disclosed transmission shift fork has improved contact areas that engage a gear that is shifted into and out of engagement with the drive train. As a result of the improved contact areas the gear and the shift fork have a more stable alignment that reduces wear during shifting and avoids uneven wear of the parts. The shift fork has an elongated pin that is positioned inside of a biasing spring. The pin has a length that is greater than the length of a compressed biasing spring, which contributes to increased stability and reduced wear from linear movement.
