  • Publication number: 20180281580
    Abstract: A transmission assembly for a hybrid vehicle includes a gearbox having an input shaft configured to be coupled with an internal combustion engine, and a pinion shaft configured to be coupled with a chassis, and a switchable planetary gear having a first connecting shaft configured to be coupled with an electric machine and a second connecting shaft non-rotatably coupled to the pinion shaft of the gearbox.

  • Publication number: 20130239729
    Abstract: An internal gear shift for a manual transmission is provided. The internal gear shaft includes a shifting shaft mounted rotationally moveably about its axis and displaceably in axial direction, counter-engagement means, and at least two engagement elements. The engagement elements interact with the counter-engagement means in order to lock the shifting shaft in at least one rotary position and in at least one stroke position. One of the engagement elements locks the shifting shaft in the stroke position and the other engagement element locks the shifting shaft in the rotary position. The engagement elements are movable against the counter-engagement means through the force of a common spring element.

  • Publication number: 20120247256
    Abstract: A shifting control is provided for a manual transmission of a motor vehicle having a shifting shaft, on which a shifting shaft lever for rotating the shifting shaft is rotationally fixed. A shifting mass is connected to an actuation end of the shifting shaft lever in a relatively moveable manner via an elastic element, so that the shifting mass and the elastic element form a vibration absorber.

  • Publication number: 20100024586
    Abstract: A manual transmission, in particular for an automobile, comprises a transmission housing (25), a drive and a driven shaft, which may be coupled to one another in different transmission ratios, a shifter shaft (1), which is rotatable and axially displaceable along predefined paths between positions corresponding to the different transmission ratios of the manual transmission, as well as at least one pair of guide elements (10, 5), which predefine these paths in a cooperating manner. The first (10) of the two guide elements is attached so that it can move with the shifter shaft (1) and the second (5) is attached to a first flange (26) connected to the transmission housing (25). The first flange (26) is fastened detachably to the transmission housing (25) and is connected to the shifter shaft (1) to form a structural unit.
