Complete drive

The system of complete drive model CX-7 borrowed from “hot” sedan Of mazda6 MPS of the previous generation, but into a somewhat truncated version. In the usual situation crossover - front-wheel-drive (to the rear wheels it is transferred not more than two percent of thrust), but rear axle is connected upon command of electronics with the aid of electromagnetic coupling, interlocked with the main drive.

Electromagnet compresses the packet of friction clutches with the aid of the manager of clutch, constantly “playing” by thrust on the rear wheels, up to the complete closing of clutch plates - in this situation thrust is distributed equally between the front and rear wheels. How to precisely stop up friction clutches - decides electronics, constantly analyzing the speed of rotation of each of the wheels, the angle of rotation of control and so on.

But, fortunately I made mistakes! It occurs, mechanics from the command of Oleg [Keselman] - the chief instructor of the sport academy Of mazda - they knew how to completely open (read - “to break”) “electronic collar” on CX-7. But now already it is possible to recall about the fact that the all-wheel-drive transmission on “[mazdovskom]” crossover is almost wholly borrowed in “charged” sedan Of mazda6 MPS, there is no only rear interlocking differential, and motor from there - 2,3- liter “four” with the turbine supercharger and the straight injection, but depowered from 260 to 235 horsepower. Entirely another matter!
