2.2.2
The drive engine (1) anchored to the upper mass (4) drives the exciter
(13). The torque is transmitted by means of a friction connection
through the centrifugal clutch (11) and the exciter V-belt (12).
2.2.3
The centrifugal clutch (11) interrupts flow of power to the exciter (13)
at low engine speed and thus permits perfect idling of the drive engine
(1).
2.2.4
The automatic V-belt pulley (10) combined with the centrifugal clutch
(11) ensures optimum tension of the exciter V-belt (12) during
operation and relief of the tension of the exciter V-belt (12) when the
machine is being relocated or transported.
2.2.5
Moreover, the automatic V-belt pulley (10) automatically adapts to the
V-belt flanks in line with the wear and thus makes the entire drive from
the engine (1) to the exciter (13) maintenance-free (see chapter
Exciter V-belt).
2.2.6
The speed of the drive engine (1) can be infinitely varied by remote
control on the throttle control lever (8). The upper (4) and lower (5)
masses are connected to each other by 4 vibration-damping rubber
metal shock mounts (14). This damping system prevents the very high
frequencies from being transmitted to the upper mass (4). As a result
the functionability of the drive engine (1) is retained in spite of the high
compaction performance. The drive engine (1) works on the diesel
principle; it is started electrically by a pinion starter (3), draws in the
combustion air through an air filter, dry (9) and is air-colled.
2.2.7
To facilitate the starting procedure (at very low temperatures, with
hand start) the drive engine (1) has an automatic decompression
mechanism (2). It ensures that compression is very low during the
cranking operation but steadily increases after a few revolutions when
it then switches over to full compression.
