3.3.3. Main transfer
The transmission will transform a torque of the engine which through small and big gear wheels of the main transfer is transferred further. The big gear wheel is fixed in the case of the main transfer. Power shafts connect the main transfer to semi-axes of wheels. The main transfer together with a transmission is mounted in one case.
In the same place four conic gear wheels (differential) connected with each other two of which are connected to power (kardanny) shafts which in turn transfer a torque to driving wheels of the car are established. The hinges of equal angular speeds (tripod type) established on shaft provide transfer of a necessary torque at changing tilt angles of shaft.
During rectilinear movement on ideally equal surface both wheels have the identical speed of rotation equal to speed of rotation of the main transfer. The differential rotates with similar speed, and conic gear wheels are at rest. At turn or arrival on roughness one of wheels passes bigger distance, than another. The differential which distributes a torque between wheels in this case comes into effect and allows conducted shaft to rotate with unequal angular speeds.
