A track maintenance system and a track maintenance machine are also provided.

Abstract: A vehicle including a frame; an engine connected to the frame, the engine comprising a crankshaft extending longitudinally, the crankshaft rotating about a crankshaft axis extending longitudinally; a transmission disposed rearward of the engine, the transmission being operatively connected to the crankshaft, the crankshaft being received at least in part in the transmission, the transmission including a plurality of axles and gears for altering a gear ratio of the vehicle, at least one of the plurality of axles rotating about an axis parallel to the crankshaft axis; a rear final drive disposed rearward of and being operatively connected to the transmission; a drive shaft assembly extending forward from the transmission; and a front final drive operatively connected to the at least one front ground engaging member, the front final drive being disposed forward of the engine, the front final drive being operatively connected to the drive shaft assembly.

Abstract: A method for carrying out work on a railway track by means of a rail vehicle, comprising a track motor vehicle with at least one electrically operable treatment device and an energy supply device for providing electrical energy, as well as a trailer wagon coupled to the track motor vehicle with an energy storage device for providing electrical energy, with the rail vehicle being driven to a track point to be treated, with the trailer wagon being decoupled from the track motor vehicle, and with the track point to be treated being treated by means of the track motor vehicle. Before and/or after treatment by means of the track motor vehicle, the track point is treated by means of the trailer wagon by supplying an electric traction drive of the trailer wagon and a treatment device of the trailer wagon with electrical energy from the energy storage device. In this way, the trailer wagon is used autonomously for track treatment.

Abstract: A transmission for a vehicle (20) includes: an input shaft (122) for connection to an internal combustion engine (52) of the vehicle (20); a gear (605) shaft (122, 199, 400A, 400B) selectively operatively connected to the input shaft (122); a clutch selectively actuatable to transmit motion between the input shaft (122) and the gear (605) shaft (122, 199, 400A, 400B) for selectively operating the transmission in one of a plurality of transmission gears (600); an output shaft (740) operatively connected to the gear (605) shaft (122, 199, 400A, 400B) at least in part by the transmission gears (600); and a transmission housing (102) at least partly enclosing the input shaft (122), the transmission gears (600), the clutch and the output shaft (740). An internal dividing wall (506, 510) defines first and second chambers (350A, 502), the internal dividing wall (506, 510) being configured to limit flow of transmission fluid between the first and second chambers (350A, 502).

Abstract: A dual-clutch transmission for use in a vehicle has a housing, a clutch pack drum adapted to rotate inside the housing, a central clutch gear connected to the clutch pack drum, a first clutch pack, a first clutch hub, a first pressure plate disposed on the first side of the central clutch gear, and a first shaft connected to the first clutch hub. The first shaft drives at least one first transmission gear when the first pressure plate squeezes the first clutch pack. The dual-clutch transmission further includes a second clutch pack, a second clutch hub, a second pressure plate disposed on the second side of the central clutch gear, and a second shaft connected to the second clutch hub. The second shaft drives at least one second transmission gear when the second pressure plate squeezes the second clutch pack. A vehicle having a dual-clutch transmission is also encompassed.

Abstract: An internal combustion engine has a crankcase having a first crankcase portion fastened to a second crankcase portion along a first plane, a crankshaft, a cylinder block defining two cylinders, two pistons, and a cylinder head. A crankshaft support defines a crankshaft support aperture. A central portion of the crankshaft is received in the crankshaft support aperture. At least one fastener fastens the crankshaft support to the cylinder block. The at least one fastener is perpendicular to a crankshaft axis and is disposed in a second plane. The crankshaft axis is normal to the first plane. The second plane is one of coplanar with and parallel to the first plane.
