Multitronic

The name Audi Multitronic used to indicate continuously variable automatic transmission. Transmission Multitronic CVT operates on the principle.

Multitronic is an automatic transmission that can transmit high-performance engine thrust without interruption during gear changes. Transmission is Multitronic CVT operates on the principle of competitive like CVT . The core Multitronic gearbox is a wide steel chain with flat cells. The chain moves and stretches between two pairs of hydraulically adjustable cones, which continuously adjusts the resulting conversion. This allows the engine always operates in the most economical speed Multitronic and therefore achieves lower fuel consumption than comparable automatic transmission.

principle function Multitronic gearbox

Principle:

The basic function of the variator is relatively simple. Axial sliding bevel gears are continuously changing the gear ratio of gearbox output shaft share (transferring engine power to the wheels) and the input shaft, which directly transmits the engine speed. Integrated control system adjusts wheel variator so that the wide range of possible ratios were always set the optimal total transfer. The engine can run at such speeds for maximum performance, the car will accelerate, but the engine speed remains constant. If the driver takes away, the control electronics selects the economical engine speed, and she turns smoothly transfer the engine speed decreases, the speed is maintained.
