Patent number: 8851028Abstract: A cooling system for a fan drive device, particularly for a wet friction clutch. The clutch shaft member is attached to a shaft mounting plate and ATF is circulated through them. The shaft mounting plate is connected in turn to an engine mounting plate which has engine coolant circulated through it at a lower temperature. The shaft mounting plate and engine mounting plates both have passageways for circulation of fluids therein.Type: GrantFiled: March 2, 2009Date of Patent: October 7, 2014Assignee: Borg Warner Inc.Inventors: Dale M. Pickelman, Jr., Theodore A. Malott, Thomas M. Tembreull

Patent number: 8726854Abstract: A fan drive system is provided having a housing connected with a pulley. A fan shaft is rotatably mounted to the housing by a clutch. A piston actuates the clutch. A pressure tube is provided for delivering pressure to the piston. A valve controls pressure against the piston. A fixed shaft rotatably supports the housing and the pulley and has passages extending through the pulley. A base connects the support shaft to a vehicle structure. An oil plate has inlets and outlets with the shaft passages. The oil plate circulates the hydraulic fluid. A coolant plate is juxtaposed between the oil plate and the structure supporting the support shaft. The coolant plate has inlets and outlets for coolant from a remote cooler.Type: GrantFiled: July 15, 2013Date of Patent: May 20, 2014Assignee: BorgWarner Inc.Inventors: Dale M. Pickelman, Jr., Thomas Tembreull, Michael Cooper, Paul Crockett, Michael Hagedorn, Justin Rumao

Publication number: 20140001005Abstract: A failsafe system for a heavy-duty multi-speed clutch includes a thermal valve coupled within a clutch pressure tube orifice circuit protecting a clutch pack from heat degradation. When oil temperature of the clutch reaches a level where thermal degradation can occur, the thermal valve allows flow into a clutch piston system at a maximum operating pressure, thereby engaging a clutch drive and cooling the clutch to a safe condition.Type: ApplicationFiled: September 2, 2013Publication date: January 2, 2014Applicant: BORGWARNER INC.Inventors: Dale M.

Patent number: 7516827Abstract: A hydraulically controlled fan drive system (12) having a method of engagement includes a housing assembly (20) containing a hydraulic fluid (48) and an engaging circuit (36). The engaging circuit (36) includes a pitot tube (152) coupled within the housing assembly (20) that receives at least a portion of the hydraulic fluid (48). An engaging circuit (36) engages the housing assembly (20) to a fan shaft (44) in response to supply of the hydraulic fluid (48) from the pitot tube (152).Type: GrantFiled: February 14, 2007Date of Patent: April 14, 2009Assignee: BorgWarner Inc.Inventors: Dale M.
