摘要:
An axle drive (1) for a motor vehicle axle includes at least a first drive unit (2), a second drive unit (2), and an output axle (6). The first and second drive units (2) are arranged such that an overall center of gravity (7) of the axle drive (1) is situated proximate to a center of the output axle (6) and/or an axis of rotation of a vehicle wheel of the motor vehicle driven by the axle drive (1).

An electric drive axle for a vehicle includes at least one first electric vehicle drive system (1) for driving at least one vehicle wheel (11, 12) and at least one connection interface (8) for at least one power take-off (PTO). The vehicle drive system (1, 13) is coupled at least to one first double shift element (6) such that, at least in a first engagement position of the first double shift element (6), the vehicle drive system (1, 13) is drivingly coupled to at least one vehicle wheel (11, 12) and, in a second engagement position of the first double shift element (6), the vehicle drive system (1, 13) is decoupled from the at least one vehicle wheel (11, 12) and is drivingly coupled to the connection interface (8) for the power take-off (PTO). A vehicle with an electric drive axle is also provided.
摘要:
A range-change transmission having a main transmission, an upstream splitter group and a downstream range group. The main transmission comprises planetary gearsets (PS2, PS3). A ring gear of gearset (PS2) is rotationally fixed to an input shaft of the main transmission. A planetary carrier of gearset (PS2) is fixed, via an intermediate shaft, to the sun gear of gearset (PS3). By way of one dual shifting element, the sun gear of gearset (PS2) can be selectively locked to the housing or rotationally fixed to the intermediate shaft. By way of two single shifting elements, the planetary carrier of gearset (PS3) can be locked to the housing or rotationally fixed to the output shaft of the main transmission. By way of another dual shifting element, the ring gear of gearset (PS3) can be locked to the housing or rotationally fixed to the output shaft of the main transmission.
摘要:
A method of actuating a shifting element with three shift positions, having a simply controlled shifting cylinder as the actuating element, a shifting element for shifting to the three shift positions and a pressure regulator, such that the shifting cylinder is designed as a cylinder with one working line and the shifting element is pushed by the spring force of at least one spring element to an end position and moved to the other shift positions in opposition to the spring force. The central position is recognized in that, when the correct shifting element position is reached, the force for moving the shifting element in opposition to the spring force abruptly increases and, because of this, a specific pressure can be set by a pressure regulator for the central position.
摘要:
A motor vehicle powershift transmission which comprising two partial transmissions (TG1, TG2) each with a respective input shaft (GE1, GE2) that can be drivingly connected, via a main separator clutch (CL1, CL2; CL1′, CL2′; CL1*, CL2*), with the driveshaft (TW) of a drive engine (VM) and, on the output side, with a common output shaft (GA). To enable powershifts without frictional slipping, the two input shafts (GE1, GE2), on the input side, can be connected to and disconnected from a respective intermediate shaft (ZW1, ZW2) by the respective main separator clutch (CL1, CL2; CL1′, CL2′; CL1*, CL2*). The first intermediate shaft (ZW1) is directly connected to the driveshaft (TW) and the second intermediate shaft (ZW2) is in driving connection with the first intermediate shaft (ZW1) by way of a variator (V) which has a continuously adjustable transmission ratio (iV) and a rest transmission ratio having the value one iV—0=1).
