Abstract: The life of a clutch is prolonged via bypassing a clutch of a gearbox and engaging a machine braking system. A change in speed or direction of a gearbox output shaft is accomplished by a management controller sending a signal through a signal transmission system to bypass the clutch and engage the machine braking system. The method includes the steps of generating a signal; processing the signal by the management controller, sending a signal to bypass the clutch; and sending a signal to engage the vehicle braking system to change the speed or direction of rotation of the gearbox. Because changes of speed and/or direction of rotation of the output shaft are assisted by the machine braking system and the clutch is at least partially bypassed, it is ensured that the braking function of the starting clutch is considerably reduced or even eliminated. This leads to a considerable reduction in wear on the clutch, so that its service life can be greatly increased.

Abstract: The gearing consists of a four-shaft toothed-gear planetary (epicyclic) transmission and a parallel, infinitely variable hydrostatic transmission, as well as additional gear wheels; toothed clutches achieve the various gears (speeds), whereas the hydrostatic transmission effectuates the infinitely variable adjustment of the infinitely variable transmission of the entire gearing; the gear shifting takes place at a synchronous speed of rotation, load-free, and without interrupting the tractive force. The special characteristic consists in the design of the toothed clutches and the control that has been provided for the shifting action, the effect being that the shifting into a new gear and out of the previous one is completely smooth and free of jolts. Apart from provding this comfortable and easy shifting action, the gearing also possesses an extensive range, overall, of transmission adjustment capability, as well as a good efficiency factor. Thus, it is very suitable for application in motor vehicles.
