The V2206PT (VT2206PT, GSS-PS) is a 6-speed, fully automat-
ic gearbox designed for an engine torque of 2200 Nm.
The fully automatic Powertronic V2206PT shifts with no
interruption in power (power-shift). The gearbox also offers
the option of manual gear shifting. In the manual mode, the
driver shifts up or down with a rocker switch on the gear
lever.
The V2206PT consists of a hydraulic torque amplifier with
lock-up, a number of planetary gears with brakes, disc
clutches that lock the different parts of the planetary gears,
and an electronically controlled regulating system that mon-
itors and regulates the shifting function. The gearboxes’
control modules are integrated into the trucks electronic
system.
The hydraulic torque amplifier boosts the engine’s torque,
which provides the truck with excellent power when mov-
ing off from a standstill. The torque amplifier absorbs sudden
loads in the driveline when starting off, and it is fitted with
an automatic direct lock-up which, after starting off, locks
the turbine- and pump wheels to each other. The direct lock-
up, which is engaged in all gears, offers a high degree of
efficiency, low fuel consumption, and low operating costs.
The range of ratios for the V2206PT offers the lowest gear
with high power when moving off, while the highest gear,
which is a direct drive gear (1:1), offers very good fuel
economy for motorway driving. The Powertronic V2206PT
is adapted for heavy-duty transport such as construction
driving and for driving in city areas, with numerous starts and
stops.
The gearbox pictured is fitted with a power take-off (option) and an
extra steering servo pump
