When at work, tractors change direction
and gear ratio regularly. Depending
on the size of the field and the type of
process, the gear is changed every
few seconds. In order to improve driver
comfort, a solution was required to allow
automatic shifting and direction changes.
Using proven core valve technology, imi precision engineering
designed a modular system that electro-hydraulically controls
the clutches and gearbox, allowing smooth gear and direction
changes. Tractors equipped with this system can be controlled
semi, or fully automatically depending on selected configuration.
There are two main systems, which can be used or combined:
Powershuttle
Changing drive direction "under the load"
The smooth forward and reverse movement in all
temperature conditions increases driver comfort and
allows the driver to focus on other tasks such as loading.
Customisable to specific requirements, the power shuttle
consists of a hydraulic valve block, electronic clutch
pedal position sensor and transmission control unit.
Powershift
Changing gears "by the wire"
The quick and easy gear shifting helps the driver to focus
on their tasks. The shifting can be done automatically when
powershift is combined with the powershuttle system, which
brings the biggest advantage for customers. Customisable to
specific requirements, the power shift consists of a hydraulic
valve block, hydraulic actuators and transmission control unit.
