To provide a transmission in which two shift stages can be simultaneously selected without enlarging the size of the transmission itself.

gear depending power take-off

engine speed p.t.o.

Optimizing heat generation within the gear box may include maximizing internal power losses in the gear box during start up.

Simultaneously, the torque of a transmission input shaft (12) associated with the transmission (4) is evaluated.

The arrangement permits a hot shift between speed ratios of a gear transmission.

Because of this the shifting movement of the stick are transferred to the gearbox while the stick remains unaffected by movements of the gearbox.

The synchronized gearbox concludes two set gear shift.

The gearbox has an input shaft and an output shaft connected to the pivot arms.

The gearbox has controllable free-wheel units (7a-7c)corresponding with pairs of toothed wheels (7a-7c) for disengaging or engaging an old or new gear and a coupling (5) mounted on the output side.

The inventive transmission ensures an especially reliable determination of the rotational speed of the transmission shaft (3).

Internal gearbox ratios (ratios of engine to gearbox output shaft revolutions

Gear box has the following role: 1, accelerated deceleration, is often said that the gearbox.

The drive torque goes nonstop to the gear box.

A rotation speed in the summarizing gear (6) is superimposed by a supplementary drive (4) on the drive speed transmitted to the running gear (8a, 8b) by the gearbox (3).
