| 20090048065 | DRIVE TRAIN AS WELL AS A METHOD OF OPERATING A HYRAULIC PUMP OF A DRIVE TRAIN - A method of operating a hydraulic pump of a drive train of a motor vehicle having a transmission with a hydrodynamic torque converter and a engine, with the input speed of the hydraulic pump being adjusted depending on the speed of the engine. The input speed of the hydraulic pump is adjusted depending on the pump speed of the torque converter, which corresponds to the speed of the engine and depends on the turbine speed of the torque converter, such that when the pump speed of the torque converter is higher than the turbine speed of the same, the hydraulic pump is operated at a speed higher than the speed of the engine. When the turbine speed of the torque converter and the pump speed of the same equalize, the excessive increase in the input speed of the hydraulic pump is reduced in relation to the speed of the engine. | 02-19-2009 |
| 20090107289 | MULTI-GROUP TRANSMISSION AND METHOD FOR CHANGING GEAR IN A MULTI-GROUP TRANSMISSION - An automated multi-group standard transmission, for a utility vehicle, and a process for changing gears in the multi-group transmission. The multi-group transmission includes at least two multi-speed transmission groups arranged one after the other, such that a multitude of gears can be shifted. A transmission input shaft that can be connected to an engine, via a startup element, is associated with a first transmission group and a second transmission main shaft is associated with a second transmission group. Load shifting mechanisms produce a temporary direct connection between the transmission input shaft and the transmission main shaft such that an intermediate gear can be shifted during a gear change from an original gear into a target gear. The load shifting mechanism enables gear changes that are virtually free of interruptions in load transfer during a gear change from a lower to a higher gear, thus increasing a high operational comfort. | 04-30-2009 |
| 20110039655 | METHOD AND DEVICE FOR CONTROLLING A CREEP MODE OF A VEHICLE HAVING A HYBRID DRIVE SYSTEM - The invention relates to a method and a device for controlling a creep mode of a vehicle having a hybrid drive system ( | 02-17-2011 |
| 20110046833 | METHOD FOR DETERMINING THE STARTING TORQUE IN A HYBRID VEHICLE - A method for determining the starting torque in a hybrid vehicle, comprising an internal combustion engine and an electric machine, wherein the internal combustion engine can be decoupled from the drive train by opening a clutch, said method providing for the determination of the starting torque by detecting the holding torque in a holding process of the vehicle with the internal combustion engine decoupled before the operating brake is engaged, wherein the holding torque detected corresponds to the minimum required starting torque. | 02-24-2011 |
| 20110100736 | HYBRID DRIVE TRAIN FOR A MOTOR VEHICLE - A hybrid drive train for a motor vehicle comprises an internal combustion engine, and electric machine, with a stator and rotor, and a transmission. A disk clutch is located in the force flow, between the combustion engine and the transmission input shaft, and an outer disk carrier of the disk clutch is fixed to a transmission input stage and an inner disk carrier of the disk clutch is connected to the combustion engine. The rotor of the electric machine drives another element of the transmission input stage, and the disk carriers of the clutch are mounted and centered by two roller bearings which center the inner and outer disk carriers relative to one another and bring them into axial alignment, and axial tolerances within the unit which comprises the electric machine, the separator clutch and the transmission input stage are compensated by displacing and aligning the disk packet of the clutch in the drive gearing of the inner disk carrier. | 05-05-2011 |
| 20110116859 | DEVICE FOR MOUNTING A HYBRID TRANSMISSION ON AN INTERNAL COMBUSTION ENGINE - A device for mounting a hybrid transmission, comprising a transmission unit and a hybrid module, onto an internal combustion engine, namely, for coupling a transmission shaft ( | 05-19-2011 |
| 20110132674 | INTERNAL COMBUSTION ENGINE/HYBRID TRANSMISSION ASSEMBLY - An internal combustion engine/hybrid transmission assembly of a motor vehicle, comprising an internal combustion engine and a hybrid module mounted on the internal combustion engine, the internal combustion engine having a flywheel. The hybrid transmission comprises a transmission and a hybrid module. The hybrid module has an electric motor which comprises a stator, on the stator side, and a rotor, on the rotor side, and the stator on the stator side comprises a stator housing, a stator liner which accommodates a stator core, and an end winding positioned on both sides of the stator core, when viewed in the axial direction. The section of the end winding, positioned on the side of the stator core facing the flywheel, is at least partially covered by a section of the flywheel, when viewed in the axial direction. | 06-09-2011 |
