AS TRONIC GEARBOX
General CF65/75/85 series
1-2
1.1 SYSTEM DESCRIPTION
The AS Tronic gearbox (4) is a fully automatic
gearbox based on a conventional mechanical
gearbox combined with an electropneumatic
shift and clutch control system.
The gearbox modulator (3) consists of the
electronic unit, sensors, a pressure limiting valve
(5) and the pneumatic shift control.
As the clutch is operated automatically, there is
no need for a clutch pedal.
Clutching and declutching are effected by
means of an automatic single-plate dry clutch
(1), the clutch unit (2) and the modulator (3).
An operating unit enables the driver to drive the
vehicle in both the semi-automatic and the fully
automatic gearbox position.
The operating unit facilitates driving in the
semi-automatic gearbox mode, thanks to the
clear gear-change pattern on the gear lever.
In the fully automatic position, clutch and shift
control takes place by the electronic shift control
in the gearbox modulator.
