On an illustration the distributive Torsen-differential in a cut is presented.
If will establish authorship of any firm in a question on introduction of a full drive for serial cars «in a decent society» it, undoubtedly, will give Audi.
The off-road car «VW Iltis», developed by request of the Bundeswehr firm Audi for Volkswagen, most likely, has served as a germinal cage for idea quattro (a full drive). The legend says:
Concepts of a full drive
Connected full drive
Until recently the concept of "the all-wheel drive car» was almost inseparably linked with concept of "the off-road car». The concept of a full drive of the last was simple enough: to a standard drive (the engine ahead, the drive back) has been simply attached one more drive, namely to the forward bridge one more transmission through a distributing box and additional propeller conducted a shaft.
Constant full drive
So, if the idea has come to a head to create the constant full drive constantly operating on all four wheels it is necessary to create the device preventing проскальзывание of wheels. This problem is solved by so-called interaxal differential.
In the winter, for example, happens so: the wheel standing on ice is turned, and the opposite wheel on a rough covering does not transfer any force and consequently costs. Clearly one: the similar differential is not necessary for a role interaxal because it is necessary to achieve opposite effect. Force should be transferred there where wheels can move the car. Namely there, where the road covering possesses good coupling. And as the driver never it foreknows, distribution should occur automatically.
