  • the adjustable multi-plate clutch can be used to create a non-positive connection between the right and left wheel sides, which is particularly important when shifting on only one side, is advantageous in either the right or the left gearbox.
  • there is an interruption in traction when shifting on the right so that the right wheel would be without drive. This is prevented by the clutch being closed and the drive torque being transmitted from the left, still driven side to the right (unpowered) wheel. This avoids an interruption in tractive power, and gearshift comfort and driving performance are increased.
  • the manual transmission has two gear stages, i. H. a first gear and a second gear, with which the needs of the vehicle, in particular a commercial vehicle, are taken into account for the approach climbing ability and the top speed.

Both gear ratios serve to further reduce the speed of the electrical machines.
  • the switching operation is basically carried out only on one side, ie either on the side of the left wheel or on the side of the right wheel, and that at the same time, i.e. during the switching process, a torque is transmitted from the driven wheel side to the non-driven side via the clutch.
  • switching e.g. B. on the right side a pulling force break up so that the right wheel is without drive.
  • the clutch is closed or partially closed, so that a torque is transmitted from the left side, which was not shifted, to the right side - this means that both wheels are driven with the same torque during the switching process and it occurs no interruption of tractive power during the switching process.

B. driving straight or driving through a right or left turn and depending on a vehicle acceleration or a vehicle deceleration regulated.
  • the clutch is closed, when cornering, the clutch is not fully closed and, depending on the direction of the curve, shifting is only allowed on the right or left side.
  • the clutch is completely closed, which corresponds to a degree of transmission of one hundred percent when a switching operation is carried out on one side.
  • the full engine torque of the driving side is transferred to the non-driven side, which applies to the vehicle traveling straight ahead.

  • a shift operation or a gear change should be carried out on the right-hand side of the wheel if the vehicle is accelerated in a right-hand turn or decelerated in a left-hand turn. This also creates a yaw moment, which causes the vehicle to oversteer. Due to the tendency to oversteer, i. H. into the curve, the safety when switching in a curve is increased.
