Patent number: 11320040Abstract: A transmission (G) for a motor vehicle includes a pump (P), an oil sump (S), a hydraulic control unit (HCU), a gear set (RS) for providing different transmission ratios between an input shaft (GW1) and an output shaft (GW2) of the transmission (G), and a cavity (HY) arranged on an input side, in which a torque converter (TC) and/or an electric machine (EM) are accommodated. The cavity (HY) is connected to the oil sump (S) via a gap (C) configured for a passive return of oil out of the cavity (HY) into the oil sump (S). In order to reduce the gap (C), a separating element (T) is configured for making it difficult for oil to flow out of the oil sump (S) to the cavity (HY). A drive train comprising such a transmission (G) is also provided.Type: GrantFiled: March 26, 2020Date of Patent: May 3, 2022Assignee: ZF FRIEDRICHSHAFEN AGInventors: Bernhard Sauter, Dirk Winkler

Patent number: 10655727Abstract: A greaser for a transmission includes a shaft (1) having an axial bore (3) and a plurality of axially spaced radial bores (6a, 6b, 6c). Each of at least one tube (8a, 8b) is inserted into a respective one of the axially spaced radial bores (6a, 6b) and extends radially inwardly into the axial bore (3) beyond a circumferential surface (4) of the axial bore (3) that is adjacent the respective one of the axially spaced radial bores (6a, 6b). Each of the at least one tube (8a, 8b) includes a slot (11a, 11b) at a tube end (10a, 10b) facing a central axis (2) of the shaft (1). The slot (11a, 11b) of each of the at least one tube (8a, 8b) extends along a central axis (9a, 9b) of the respective tube (8a, 8b) into an interior space of the axial bore (3).Type: GrantFiled: August 24, 2016Date of Patent: May 19, 2020Assignee: ZF FRIEDRICHSHAFEN AGInventors: Rainer Grundler, Markus Herrmann, Thilo Schmidt, Dietmar Gehring, Dirk Winkler

Publication number: 20170261101Abstract: A drag torque reduction device for an automatic transmission includes a hydraulic controller with a parallel connection of a pressure relief valve, a constant aperture and a temperature-dependent, switchable aperture that is positioned upstream of a radiator relative to a flow of fluid to the radiator. The parallel connection is disposed between a first control edge of a converter switching valve and a first line. The first line leads to both to the radiator and through a check valve to the converter ring. The first control edge of the converter switching valve is open and lubricating oil flows through the parallel connection when the converter switching valve is in a first switching position. The first control edge of the converter switching valve is closed and lubricating oil does not flow through the parallel connection when the converter switching valve is in a second switching position.Type: ApplicationFiled: June 30, 2016Publication date: September 14, 2017Inventors: Markus Herrmann, Thilo Schmidt, Gerhard Martin, Ahmed Mouhcine, Rainer Grundler, Dirk Winkler, Valentine Vincent

Publication number: 20170261091Abstract: A drag torque reduction device for an automatic transmission includes a hydraulic controller with a diversion for excess cooling oil into an oil sump that is positioned upstream of a radiator relative to a flow of fluid to the radiator. The diversion includes a temperature-dependent, switchable aperture and a switching valve. The temperature-dependent, switchable aperture is configured to close above a temperature threshold. The switching valve is configured to close above a threshold pressure.Type: ApplicationFiled: June 30, 2016Publication date: September 14, 2017Inventors: Markus Herrmann, Thilo Schmidt, Gerhard Martin, Ahmed Mouhcine, Rainer Grundler, Dirk Winkler, Valentine Vincent
