distribution (central) The differential serves to align the front and rear transmissions. (Front and rear axle differentials operate independently of it.)
It is located - not perceived as a separate unit from the outside - at the rear of the manual gearbox. Engineers say: integrated.
The name Torsen comes from the Gleason gearbox company where this differential was invented. Its name is derived from the English letters Torque Sensing, which means «feeling the torque». Thus, it is in this concept that the description of the function already lies, since:
- the differential transmits increased force to the drive of the axle that has the best grip;
- it happens so efficiently (due to the design), that this axle can transmit 3.5 times more force than the other axle;
- but with equally good soil properties, an equivalent distribution of the drive to the front and rear axles is carried out, i.e. there is no preference for one axle due to the design.
Operating principle
The operation of the torsion differential is based on the principle of a worm drive and uses its fundamental principles:
- the worm drive can be designed in such a way that it will have a high or low locking ability (the amount of blocking in this case is a multiply increased force with which the gear must be rotated);
- the value of the blocking value depends on the angle of the worm, i.e. the worm has a lot of flat or few steep turns;
- an example of a high-lock flatworm is a jack, in which the knee the worm acts on lifts the car, but the car can never move the knee with its weight.
Location
By intelligent arrangement of a total of eight worm wheels and 12 gears, in combination with a differential housing, a hollow shaft, a drive shaft in front and a drive shaft in the rear, the function described in the penultimate paragraph is achieved in the best possible way.
