  • Patent number: 11320040
    Abstract: 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.

  • Patent number: 10655727
    Abstract: 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).

  • Patent number: 10113635
    Abstract: A drag torque reduction device for an automatic transmission includes a hydraulic controller with a radiator. In one embodiment, the drag torque reduction device also includes a parallel connection of a pressure relief valve, a constant aperture and a temperature-dependent, switchable aperture positioned upstream of the radiator. In another embodiment, the drag torque reduction device includes an overflow cooling oil diversion with a temperature-dependent, switchable aperture and a pressure relief valve that is positioned upstream of the radiator.

  • Publication number: 20170261101
    Abstract: 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.

  • Publication number: 20170261091
    Abstract: 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.
