Fig. 26 Rubber track structure
The structure of the rubber track is shown above (fig 26). The steel cables and the
metal core are embedded in the rubber. The curved profiles function gives stability
on soft terrain. The wheel guides, located on the inside of the track, prevent the
track from sliding off the guide rollers.
Breakage of steel cables:
Excess track tension can cause steel cables to break in the following
conditions:
-
when stones or foreign matters accumulate between the track and the
undercarriage frame;
-
when the track slips off its guide system;
-
in case of great friction, e.g. rapid changes in direction.
Breakage of metal core:
Excess track tension can cause the metal core to bend or break, just like the steel
cables as stated above.
Other causes may include:
-
improper contact between track and sprocket;
-
rotation of internal rollers;
-
operation on sandy terrain.
Maintenance of Chassis
See a separate manual for the tracked undercarriage.
