摘要:
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 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.
摘要:
A method for controlling of a drive train of a vehicle having a multi-group transmission, an output mechanism and a control apparatus for the regulation of the drive train. The multi-group transmission consists of an automatic transmission and a range group. To change the ratio of the range group the drive train is relieved of load; a shifting element of the range group is closed; a shifting element of the range group is synchronized and opened; and a ratio of the automatic transmission is so altered that a change of the ratio of the multi-group transmission is less than in a case of an individual alteration of the ratio of the range group.
摘要:
A method for controlling a drivetrain (1) in a motor vehicle is disclosed, in particular in an off-road vehicle with a drive unit (2), a multi-group transmission (4) and an output. The multi-group transmission (4) comprises at least an automatic gearbox (8) and a subsequent range transfer box (9) which may be switched by means of switching elements (24, 25). On changing the ratio in the range transfer box (9), a synchronisation of the switching element (24 or 25), for switching in the range transfer box (9), is carried out by means of a controller of switching elements in the automatic gearbox (8).

A distributor transmission (8) having at least three shafts (11, 12, 13) for distributing a drive torque (M_GE) as needed to at least two drive axles (4, 5). A first shaft (11) is operatively connected with the first drive axle (5) and can be loaded with the drive torque (M_GE). The second shaft (12) is operatively connected with the second drive axle (4) and a torque (M_E) of a machine device (14) on a third shaft (13) can be applied which influences a degree of distribution (P_VA/P_GES) of the drive torque (M_GE) between the drive axles (4, 5).

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.
摘要:
A vehicle with a drive engine, with at least two vehicle axles and a transmission unit for variable distribution of drive torque from the drive engine in the vehicle's longitudinal direction between the vehicle's axles. The transmission unit is made with an input shaft and at least two output shafts, at least two planetary gearsets and an electric machine arranged between two mutually connected shafts of the planetary gearsets for distribution of the torque delivered via the transmission input shaft between the transmission output shafts as a function of a torque produced by the electric machine. The electric machine is in active connection with the transmission unit connecting between the two interconnected shafts of the planetary gearsets and the planetary gearsets are made with different transmission ratios so that the electric machine is driven by virtue of a speed difference between the actively interconnected shafts of the planetary gearsets.
摘要:
A transfer case (12) for distributing a driving torque of an input shaft (19) between two drivable output shafts (22, 29) is described. The transfer case (12) is realized with two controllable and adjustable frictionally engaged clutches (k_VA, k_HA), which are arranged between the input shaft (19) and the output shafts (22, 29) and whose transfer capabilities can be respectively adjusted via separate actuating devices (10, 11). A driving torque can be distributed between the drivable output torques (22, 29) in dependence upon the set transfer capabilities of the clutches (k_VA, k_HA). One clutch (k_HA) can also be radially enclosed by the other clutch (k_VA).
