Patent number: 11754169Abstract: A vehicle transaxle includes a housing, an electric machine, and rotating components. The housing defines an internal cavity, a first channel, and a second channel. The first and second channels branch from a common inlet. The electric machine and rotating components are disposed within the internal cavity. The first channel is configured to deliver fluid to the electric machine for cooling. The second channel is configured to deliver the fluid to the rotating components for lubrication. The cooling channel is sized relative to the lubrication channel such that the fluid is biased from the inlet and toward the second channel in response to a temperature of the fluid being less than a threshold and is biased from the inlet and toward the first channel in response to the temperature of the fluid being greater than the threshold.Type: GrantFiled: July 7, 2022Date of Patent: September 12, 2023Assignee: Ford Global Technologies, LLCInventors: William David Guarino, Bharath Madduri, Derek Kinch, Kyle Ogrodzinski

Patent number: 11258316Abstract: A motor for an electric vehicle includes a motor housing for receiving a stator. A plurality of caps each have an outer rim and a washer portion defining a bolt receiving opening. The outer rim of each of the caps is press-fit into the receptacles in the motor housing. The caps are each attached to the stator by one of the bolts. The heads of the bolts clamp the cap to the stator to retain one end of the stator. The outer rim holds the cap in the motor housing while the washer portion flexes axially in response to thermal expansion and contraction of the motor housing. A method is disclosed for assembling the stator into the motor housing.Type: GrantFiled: October 4, 2019Date of Patent: February 22, 2022Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: William David Guarino, Michael Coury, Kenneth Gerard Kraft, Peter Alexander Szpara, Siraj Siddiqui, Cyrille Goldstein
