  • Patent number: 8430779
    Abstract: A power-dividing gear train assembly for motor vehicles includes a differential that outputs torque to two output shafts. The output torque applied to the output shafts is changeable by using a superimposing gear train, which comprises a plurality of epicyclic gear trains and is drivingly connected indirectly or directly with the output shafts. A drive motor is drivingly coupled to the superimposing gear train and the transmission ratio of the superimposing gear train is set such that an output shaft of the drive motor is still when the output shafts are rotating synchronously. To achieve a more precise and quicker-reacting redistribution of the drive torques, at least one epicyclic gear train, which reduces torque and cooperates with the differential, is connected upstream of the superimposing gear train.

  • Publication number: 20100167862
    Abstract: The invention relates to a power-dividing gear train assembly for motor vehicles, having a driven differential that outputs to two output shafts via compensating elements, wherein the output torque at the output shafts is changeable by using a superimposing gear train, which is formed by epicyclic gear trains and is drivingly connected indirectly or directly with the output shafts, and a drive motor coupled thereto, and wherein the transmission ratio of the superimposing gear train is set such that the drive motor is still when the output shafts are rotating synchronously. For achieving a more precise and quicker-reacting redistribution of the drive torques in a structurally-advantageous construction of the superimposing gear train and the drive motor, it is proposed that at least one epicyclic gear train (Uz, Uz2, U1, U2), which reduces torque and interacts with the differential (U), is connected upstream to the superimposing gear train (26).

  • Patent number: 6632155
    Abstract: The invention relates to a drive system, especially for motor vehicles, with a first power source (10), especially an internal combustion engine, and a second power source (20), especially an electric motor. The power sources acts upon a gearbox (14) that is provided with a plurality of gearwheel sets which modulate. The first power source is linked with the gearbox via a clutch (L1) and the second power source is linked with the gearbox directly. The aim of the invention is to provide a construction that is favorable both in terms of design and functionality. To this end, the first power source acts upon a shaft (12) that carries the one gearwheels of the gearwheel sets and the second power source acts upon a second shaft (16) that carries the other gearwheels of the gearwheel sets. A separate output shaft (22) can be optionally coupled to the first (12) or the second (16) shaft.

  • Patent number: 6491602
    Abstract: The invention relates to a drive assembly, in particular for motor vehicles. Said assembly comprises a first drive source, in particular, an internal combustion engine and a second drive source, in particular, an electric motor. Said drive sources operate on a variable transmission as speed converters, whereby the first drive source is connected via a clutch to the transmission and the second drive source is connected directly to said transmission. In order to achieve an optimal construction in terms of form and function, the first drive source impinges upon a first conversion element of the variable transmission, the second drive source impinges upon the second conversion element and a separate drive shaft is provided which can be selectively coupled to the first or second conversion element.
