摘要： Methods and systems for improving operation of a vehicle driveline that includes an engine and an automatic transmission with a torque converter are presented. In one non-limiting example, the engine may be stopped while a vehicle in which the engine operates is rolling. A transmission coupled to the engine may be shifted as the vehicle rolls so that vehicle response may be improved if a driver requests an increase of engine torque.

摘要： A multi-speed automatic transmission includes a housing, a transmission input shaft, and a plurality of clutches. Different combinations of clutches of the plurality of clutches are engaged to generate different gear ratios corresponding to respective forward speeds of the automatic transmission. The plurality of clutches are positioned within the housing and include a first friction clutch coupled the input shaft and having a first hub, and a second friction clutch having a second clutch hub. The second friction clutch is disposed about the input shaft and radially nested within the first clutch hub such that the second friction clutch is positioned radially between the first clutch hub and the input shaft. The first friction clutch is engaged to generate at least two forward speeds of the transmission and the second friction clutch is engaged to generate seven forward speeds of the transmission including the two forward speeds.

摘要： A driven wheel unit includes an electric motor coupled to a two-speed, three stage planetary drive assembly and has a width dimensioned for traveling between rows of crop. A wheel hub is supported on an outer surface of a fixed housing by large diameter wheel bearings surrounding both a motor-containing cavity and an adjacent cavity containing first and second planetary stages. Nested radially and surrounding the two planetary stages are two SAHR disc clutches including pistons engaging inner and outer surfaces of a compact piston guide member. The third stage planet carrier defines a cap and is fixed to an axially outer end of the wheel hub. A third stage ring gear has an outside diameter approximately equal to that of the wheel bearings and has an inside diameter fixed to the housing by a planar, annular wheel bearing retainer plate that is fixed to an end of the housing.

摘要： A multi-stage transmission for a motor vehicle is disclosed. The transmission has a transmission input shaft, at least four planetary gear stages which are disposed one behind the other along a main axis of rotation, and at least one combined gear shift unit which is configured as a brake and has a rotatable coupling element as well as a friction-locking unit and a form-locking unit connected in parallel with the friction-locking unit, which are in each case provided in order to connect the rotatable coupling element fixedly to the housing. One of the planetary gear stages is associated with the combined gear shift unit and includes a transmission element which is permanently connected non-rotatably to the rotatable coupling element. The planetary gear stage associated with the combined gear shift unit includes a further transmission element which is permanently connected non-rotatably to the transmission input shaft.
