ABSTRACT

The paper presents results of traction studies of a tyre
4.00-10 and 5.00-10 (single and double – twin-transformed) on four different
surfaces (soil in the traditional cultivation, a layer of snow, a ground forest
road and a forest road with hardened surface). Maximum traction forces generated
on those surfaces were analyzed as well as the values of traction performances
and coefficients of adherence. The studies showed that twin-transformation of
tyres always results in an increase of traction forces and an increase of the
value of traction performances. The largest traction forces, traction performances
and adherence coefficients were established on a forest road with hardened surface,
whereas the smallest ones – on the snow.

Key words: changeable conditions of exploitation, traction forces, traction performances, tyres.
