摘要： A drive system has at least two drive units each including a central shaft, a central gear wheel connected to the central shaft such that the central gear wheel rotates at a speed of the central shaft, and two to four decentralized gear wheels distributed over the circumference of the central gear wheel and meshing with the central gear wheel such that the speed of the central gear wheel is at least 0.5 times the speed of the decentralized gear wheels. The rotational speed of the central gear wheel is at least 0.5 times the rotational speed of the decentralized gear wheels. Each decentralized gear wheel is coupled directly and without transmission to a single electric machine, or to two electric machines of a plurality of electric machines. The central shafts of the drive units are coupled to form a series connection of the drive units.

摘要： A drive system for driving a and/or being driven by a coupled machine comprises an output for driving the and/or by the coupled machine, a first machine unit with at least one electric machine and a second machine unit with at least one electric machine. The first machine unit has a transmission gear and the drive system has a first switching unit which is set up in such a way that, in a first operating state of the first switching unit, it operatively connects the transmission gear of the first machine unit and the output in a torque-transmitting manner and, in a second operating state of the first switching unit, this operative connection is interrupted. In addition or alternatively, the drive system has a first switching device which is set up in such a way that, in a first operating state of the first switching device, the electrical machine of the first or second machine unit and a power supply and/or energy storage device are electrically connected by it, and, in a second operating state of the first switching device, said connection is disconnected and an active short circuit of said electrical machine is effected.

摘要： A steering drive system for a wheel side steered vehicle includes a coupling element couplable to output drives of the vehicle in order, when an amount of a superposition rotational speed of the coupling element is greater than zero, to provide at the output drives, which are driven at a basic rotational speed on the basis of a travel drive system of the vehicle, for steering the vehicle a superposition rotational speed which is to be superposed on the basic rotational speed. The system further includes at least one first electric machine whose rotational speed can be variably set or controlled, with a power summation and/or power branching unit, wherein a first connection of the power summation and/or power branching unit is coupled to a shaft which can be coupled, in particular via a defined transmission ratio, to a shaft of the travel drive system. A second connection of the power summation and/or power branching unit is coupled to the at least one first electric machine, and a third connection of the power summation and/or power branching unit is coupled to the coupling element, in particular via at least one defined transmission ratio.

摘要： A drive arrangement of a working machine to be driven at a variably adjustable speed includes a differential gear, a first drive unit coupled to a first element of the differential gear, a working machine coupled to a second element of the differential gear, and a second drive unit coupled to a third element of the differential gear. The speed of the second drive unit can be superimposed on a speed dependent on the speed of the first drive unit, whereby the first or second drive unit can be driven at a variably adjustable speed. The drive arrangement includes an auxiliary gear stage and a switching element interacting with the auxiliary gear stage, wherein, when the switching element is closed, the auxiliary gear stage is load-transmitting and the speeds of the first and second drive units are coupled as a function of at least one transmission ratio of the auxiliary gear stage, and when the switching element is open, the auxiliary gear stage is load-free and the speeds of the first and second drive units are decoupled.
