摘要:
A transmission device for distributing drive torque to two output shafts, including a differential with a driven differential cage. The outputs are connected to the differential, in which, between the differential cage and the output of one side, viewed in the direction of the flow of force, two plus-planetary gear trains are arranged adjacent and co-axial with the output. The gear trains have first and second sun gears, first and second planetary ranges with the first sun gear being connected to the differential and the second sun gear being connected with the first sun gear and the output. The segment of the planetary gear for actuating the transmission device or transferring torque is able to be braked and the segment of the planetary gear train reversing drive is coupled via a switching element to the transmission housing.
摘要:
A transmission for distributing a drive torque between at least two drive output shafts with at least two planetary gearsets, each having at least three-shafts. In each case, a shaft of a planetary gearset is connected to a drive input shaft and a second respective shaft of a planetary gearsets is the drive output shafts. A respective third shaft of the planetary gearsets communicates with a brake such that a degree of distribution of the drive torque between the two output shafts varies as a function of the transfer capacities of the brakes. A transmission device controls and regulates a drive torque from a drive engine between the two output shafts of the transmission device. The transfer capacities of the two brakes are adjusted such that one brake is in a synchronous condition and the transfer capacity of the other brake is varied between a lower and an upper limiting value.
摘要:
A transmission for distributing a drive torque to two drive output shafts, with two planetary gearsets each having at least three shafts. A respective shaft of a planetary gearset is connected to a drive input shaft. Furthermore, one shaft of each planetary gearset constitutes one of the output shafts and in each case at least one further shaft of a planetary gearset is connected with a shaft of another planetary gearset. An operation-status-dependent torque of one shaft can be supported by the connection, depending on an operating status of the other shaft connected thereto, in such manner that when there is a rotation speed difference between the output shafts, a speed-difference-changing torque is applied to the planetary gearsets. Furthermore, a drive train is proposed, in which a drive torque from a drive-power-source is distributed variably in the longitudinal and transverse direction of the vehicle in an operation-status-dependent manner.

A power train (1) of an all-wheel drive vehicle with at least two driven vehicle axles (4, 5), with a main transmission (3) placed between a main engine (2) and the vehicle axles (4, 5), capable of displaying different conversion ratios, which has three control and adjustment frictional clutches (k_VA, k_HA_L and k_HA_R). The first clutch (k_VA) is placed between the main transmission (3) and the first vehicle axle (4) and the second clutch (k_HA_L) and the third clutches (k_HA_R) are respectively located between an axle transmission (7) and two driven wheels (5A, 5B) of the second vehicle axle (5). The respective transfer capabilities of the clutches (k_VA, k_HA_L, k_HA_R) can be adjusted with an actuator (8), and the driving torque between the driven vehicle axles (4, 5) can be distributed depending on the adjusted transfer capabilities of the clutches (k_VA, k_HA_L, k_HA_R).

摘要:
A vehicle is described, with a drive engine arranged in the transverse direction of the vehicle, with vehicle cross-shafts of a vehicle axle that can be driven by the drive engine and with a transmission unit for the variable distribution of the drive torque from the drive engine in the vehicle's transverse direction between wheels connected to the vehicle cross-shafts. The transmission unit has an input shaft and two output shafts, with two planetary gearsets and an electric machine arranged between two interconnected shafts of the planetary gearsets for the variable distribution of the torque delivered by the input shaft between the two output shafts as a function of torque produced by the electric machine. The electric machine is brought into active connection with the transmission unit and with the drive engine via shiftable clutch devices such that the degree of distribution between the output shafts of the transmission unit can be varied when the electric machine is operating as a motor and as a generator. The electric machine can be driven directly by the drive engine to operate as a generator.
