The vibration needed for the soil compaction is generated in the exciter
(9). The exciter is tightly bolted to the lower mass (8). It has been
designed as a central exciter, therefore allowing - by ways of a relative
rotation between the excentric weights (1) - the rotation of the direction
of the vibrations. Thanks to this technique, it becomes possible to
change over from forward travel to a right or left turn or to reverse travel
of the vibratory plate while during the compaction operation. This
process is controlled by means of a set of electro-hydraulic switching
valves.
The drive engine (12) anchored to the upper mass (7) drives the
exciter (9). The torque is transmitted by means of a friction connection
through the centrifugal clutch (4) and the exciter V-belt (10).
The centrifugal clutch interrupts flow of power to the exciter at low
engine speeds and thus permits perfect idling of the drive engine.
