A rubber caterpillar track () has an interior surface () intended to collaborate with drive means, and a tread () comprising a tread pattern () formed of N relief elements made of an elastomeric material which are intended to come into contact with the ground in order to give the caterpillar track () traction, each element of the tread pattern () comprising a leading face () intended to transmit force, characterized in that: a. the leading face of n tread pattern elements, the number n being at least equal to 0.2×N, is inclined with respect to a direction (OZ) normal to the bearing surface by an angle α comprised between 45 degrees and 75 degrees; and b. the tread is notably made of an elastomeric material of which the shore A hardness, measured in accordance with the standard ASTM D2240, is greater than or equal to 65.

Tread of a vehicle track

A tread () for the driven axle of an agricultural vehicle having tread pattern elements () extending radially towards the outside from a bearing surface (). The tread pattern elements have, in the central part of the tread, a series of blocks () juxtaposed with one another in the longitudinal direction and separated by transverse cuts (), and having, in the rolling direction (), a leading face, a contact face and a trailing face. The leading face having a radial height greater than the radial height of the trailing face. The contact face being oriented at an angle α with respect to radial direction Z, α being between 93 and 105° and radial depth PR of the transverse cuts () being at least 50% of the radial height of the leading face, the width of the blocks representing at least 15% of the width of the tread.
