Publication number: 20240392710Abstract: The present disclosure relates to an engine assembly for a vehicle. The engine assembly includes an oil reservoir to receive oil from a crankcase. The oil reservoir is external to the crankcase and positioned rearward of the crankcase. The engine assembly also includes at least one scavenge pump configured to pump the oil from an oil collection pan. The scavenge pump is positioned within the crankcase forward of the crankshaft and includes a suction tube extending rearwardly to a low point in the oil collection pan. The engine assembly further includes a drive mechanism to drive a feed pump and the at least one scavenge pump with the crankshaft. The drive mechanism includes an oil pump shaft to drive the feed pump and includes a gear train coupled to the oil pump shaft to drive the at least one scavenge pump.Type: ApplicationFiled: April 29, 2024Publication date: November 28, 2024Inventors: Ralf Centmayer, Jochen Hämmerle, Dirk Winkler

Publication number: 20240392721Abstract: The present disclosure relates to an engine assembly for a vehicle. The engine assembly comprises an engine including an extended crankshaft with additional main bearings, an alternator or a generator, a drive chain assembly, and a starter motor assembly. The engine may be used in different models of the vehicle having different characteristics, which enables to interchange or replace an internal generator with an external alternator, and vice versa in addition enable to use a common starter motor assembly, crankshaft, crankcase, and drive chain assembly for both engine configuration without modifying a basic design of the engine. Further, placement of the starter motor assembly provides a compact arrangement. In addition, the extended crankshaft with the additional main bearings enables low noise level operation, avoids additional shafts and roller bearings to be attached, and cost effective. Similarly, the drive chain assembly produces less vibration and noise.Type: ApplicationFiled: May 21, 2024Publication date: November 28, 2024Inventors: Ralf Centmayer, Jochen Hammerle, Dirk Winkler, Jan Schempp, Dominik Hermann

Publication number: 20240392720Abstract: The present disclosure relates to a coolant system to cool an engine assembly. The coolant system includes a coolant pump impeller with multiple concentric ribs extending axially on a first side of the coolant pump impeller and multiple vanes extending axially on a second side of the coolant pump impeller. The coolant system also includes a coolant rail to collect coolant from a water jacket that surrounds portions of cylinders and a cylinder head of the engine assembly. The coolant system further includes bleed fittings to remove trapped air as the coolant system circulates coolant through the engine assembly. First and second bleed fittings are provided on opposite corners of the engine assembly such that either the first or the second bleed fitting is at a highest point of the coolant system based on an engine orientation of the engine assembly.Type: ApplicationFiled: April 30, 2024Publication date: November 28, 2024Inventors: Ralf Centmayer, Dirk Winkler

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
