摘要:
In an automatic load shift transmission including a transmission output shaft arranged coaxially with respect to a twin clutch disposed at the transmission input side, a countershaft is provided comprising only fixed gears and all the freely movable gears and the shift elements are arranged on the shafts extending along the axis of the twin clutches and the input and output shafts.

In an automated split path transmission with at least six forward speeds and three characteristic transmission steps (sI, sII, sIII), which decrease with the height of the forward speed, one of the forward speeds is a direct gear and the power of a further forward speed passing through two constant gearsets of the split path group.
摘要:
In a transmission for a motor vehicle of a reduction gearing design with power branching including a main shaft and a counter shaft, a first component transmission and a planetary gear unit, power is branched to the countershaft by the first component transmission in certain gears and recombined via the planetary gear unit and a direct power transmission path is provided wherein the countershaft is decoupled selectively by means of a control device.
摘要:
In a dual clutch transmission with a main group and final shift group, with a coupling device for coupling a transmission element of the main group to a final shift group transmission element of the final shift group, the transmission comprises two transmission gears (V4L, V5L, V1 H, V2H) which can be formed simultaneously with one of the transmission gears (V4L, V5L) assignable to a lower group of the final shift group and another of the transmission gears (V1H, V2H) assignable to an upper group of the final shift group.

In a commercial vehicle transmission with a main group and a downstream group including a downstream group countershaft, the downstream group includes means for decoupling the downstream group countershaft in direct through drive so that in direct through-drive the countershaft does not run in an oil sump and no churning losses occur thereby increasing vehicle transmission efficiency.

摘要:
In a drive train of a motor vehicle having an engine and a dual-clutch gearbox for transmitting engine power to driven wheels of the motor vehicle, an additional gearbox having at least two shift positions with different transmission ratios is arranged between the engine (5) and the driven vehicle wheels in series with the dual clutch gearbox.
