Four-wheel drive On an illustration the distributive Torsen-differential in a section is presented. If establish authorship of any firm in a question of introduction of the four-wheel drive for the serial cars "in decent society", then it will be given, undoubtedly, by Audis.
The VW Iltis SUV developed by request of the Bundeswehr by Audi for Volkswagen, most likely, served as a germinal cage for the idea of quattro (four-wheel drive). The legend says: Concepts of the four-wheel drive The connected four-wheel drive Until recently the concept of "the all-wheel drive car" was almost inseparably linked with a concept of "the off-road car". The concept of the four-wheel drive of the last was quite simple: one more drive was simply attached to the standard drive (the engine ahead, the drive back), namely to the forward bridge one more transmission via the transfer case and the additional driveshaft conducted. Constant four-wheel drive So if the idea to create the constant four-wheel drive, permanent on all four wheels came to mind, then it is necessary to create the device preventing wheel slip. 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 therefore costs. One is clear: the similar differential does not suit for a role interaxal because it is necessary to achieve opposite effect. Force has to be transferred there where wheels will be able to move the car. Namely there, where the paving possesses good coupling. And as the driver never foreknows it, distribution has to happen automatically. |
