| 20080234093 | Multi-Speed Gearbox - The eight-gear transmission comprises an input shaft (AN), an output shaft (AB), four planetary gearsets (RS | 09-25-2008 |
| 20080269004 | Multi-Speed Transmission - The 8-stage transmission possesses one input and one output shaft (AN, AB), four planetary gearsets (RS | 10-30-2008 |
| 20080287249 | PLANETARY TRANSMISSION - A planetary transmission with at least one planetary gearset including planetary gears supported on a planetary gear carrier. The planetary carrier has inner teeth, which engage outer teeth of a shaft to form a lock tooth array. To secure the planetary carrier axially on the shaft, the planetary carrier is placed with one axial end against a stop on the shaft and the opposite axial end is fixed axially with a circlip fit into a circlip groove in the shaft. At least one axially adjacent component is supported against the planetary carrier such that an axial bearing is arranged radially and axially adjacent to the circlip and includes a roller group guided in a cage and a first check-disk A second check-disk is arranged radially opposite and at a distance from the circlip in such manner that when assembled, the circlip cannot escape from the circlip groove in the shaft. | 11-20-2008 |
| 20080293536 | PLANETARY TRANSMISSION WITH A DISK CLUTCH OR A DISK BRAKE - A transmission with a planetary gearset including planetary gears supported on a carrier, with a disk clutch or brake including a disk carrier which, via an integral cylindrical portion, is fixed to a shaft that supports the disk carrier, such that the carrier rotates on the cylindrical portion and the carrier is supported by a first axial bearing on the disk carrier and a second axial bearing on a sun gear, which engages the planetary gears, and with an oil supply for lubricating and/or cooling bearings, disk clutch and/or brake components. The first axial bearing includes rollers guided in a cage and first check-disk adjacent the carrier and a second check-disk rollers. The first check-disk flanged disk with a section for rollers of the first axial bearing and with a cylindrical section offset from the rolling section. | 11-27-2008 |

| 20100048344 | MULTI-SPEED TRANSMISSION - A transmission having input and output shafts, gearsets (RS | 02-25-2010 |
| 20100178102 | ROTATIONALLY FIXED CONNECTION OF TWO PARTS OF A TRANSMISSION FOR TRANSMITTING TORQUE - A rotationally fixed connection of first and second components ( | 07-15-2010 |
| 20100243401 | SHIFTING ELEMENT OF A GEAR BOX - A shifting element of an automatic transmission with a shifting element piston that can be hydraulically actuated via an engaging pressure space and with a way of pressure compensation which compensates for dynamic engagement forces that act on the shifting element piston and are produced in the engaging pressure space filled with hydraulic liquid by its rotation. The way of pressure compensation comprising of at least one pressure compensation space that can be fed with pressure compensation liquid in which dynamic compensation forces, directed opposite to the dynamic engagement forces, can be produced by virtue of the rotation. To achieve effective passive compensation of dynamic hydraulic pressures with comparatively little radial structural space occupation, at least two pressure compensation spaces, opposite the engaging pressure space, are arranged in a cylinder space of the shifting element piston axially next to one another. | 09-30-2010 |
| 20100279814 | 10-GEAR AUTOMATIC TRANSMISSION - An automatic planetary transmission comprising a drive input shaft (AN), a drive output shaft (AB), first, second, third and fourth planetary gearsets (RS | 11-04-2010 |
| 20100331137 | MULTISPEED TRANSMISSION - A transmission having input and output shafts, gearsets (RS | 12-30-2010 |
| 20110077119 | MULTI-SPEED TRANSMISSION - The 8-gear transmission comprises an input shaft (AN), an output shaft (AB), four planetary gearsets (RS | 03-31-2011 |
| 20110143876 | AUTOMATIC TRANSMISSION FOR A VEHICLE - A transmission for a vehicle with a clutch and/or a brake which is hydraulically actuated by a cylinder and a piston actuator. A pressure chamber is located between the cylinder and the piston and a hydraulic pressure medium flows into the pressure chamber via an inlet. The pressure medium is supplied to the pressure chamber via a component fixed on the housing, a rotary passage between the fixed component and the rotatable component and then via the rotatable component. The radial distance of the radial middle of the rotary passage is larger than the smallest radial distance and smaller than the largest radial distance of the pressure chamber from the rotation axis of a central shaft of the automatic transmission. The radial arrangement of the rotary passage, between the radially smallest and largest diameters of the pressure chamber, neutralizes centrifugally generated forces on the pressure medium in the pressure chamber. | 06-16-2011 |
