Patent number: 9939050Abstract: The present invention provides improved, real time sensing of pressure supplied to the hydraulic operator of a clutch for a motor vehicle driveline power take off. A proportional sensor in the hydraulic line to the power take off clutch actuator provides a data signal in real time of the actual pressure applied to the clutch actuator. This signal is provided to the power take off control module (PCM) and/or to the transmission control module (TCM). The power take off control module, having instantaneous data regarding the pressure applied to the hydraulic operator achieves two important operating functions: monitoring and feedback.Type: GrantFiled: February 18, 2016Date of Patent: April 10, 2018Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Timothy J.

Patent number: 9850991Abstract: Assembly tools or aides assist the installation of chains and sprockets for a power take off in a motor vehicle automatic transmission. A first tool is an assembly clip having a semi-circular channel that engages the periphery of a chain disposed about a socket. The clip facilitates installation of the chain and a first sprocket through a slot or other opening in the side of a transmission housing while a second sprocket is being secured to a transmission shaft and the chain is engaged thereabout. The clip also facilitates positioning of the first sprocket in a desired location, typically on a driven shaft while retaining the chain thereabout. A second tool includes a pair of elongate, parallel pins which cooperate with the clip and the first sprocket to hold it in place during assembly of certain components of the transmission such as a power take off shaft or bulkhead.Type: GrantFiled: July 31, 2015Date of Patent: December 26, 2017Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Timothy J.

Patent number: 9597958Abstract: A power take-off (PTO) system for a motor vehicle includes a PTO housing. The PTO housing is mounted to a transmission case. A disconnect clutch assembly is positioned within the PTO housing acting when supplied with a first volume of a pressurized oil from the transmission case to engage an output shaft member. A controlled lube oil circuit is isolated from the first volume of the pressurized oil. The controlled lube oil circuit supplies a second volume of the pressurized oil directly to the disconnect clutch assembly to lubricate the disconnect clutch assembly. A lube oil drain return is connected to the PTO housing. The lube oil drain return receives oil that collects inside the PTO housing to be returned to the transmission case.Type: GrantFiled: August 11, 2015Date of Patent: March 21, 2017Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Timothy J.
