Track section with crossbar and track belt formed by such track sections

A track section adapted to be linked to a plurality of similar track sections to form a track belt (1) for mounting around the outer periphery of vehicle tyres, wherein the track section (10) comprises:

• an elongated crossbar (11) having a tyre-facing inner side (13) and a ground engageable outer side (14) opposite to the inner side;
• a first lateral support member (12a) mounted to the crossbar (11) at first end section (11a) thereof;
• and
• a second lateral support member (12b) mounted to the crossbar (11) at an opposite second end section (11b) thereof,
• the first and second lateral support members (12a, 12b) protrude on the inner side (13) of the crossbar (11) and are spaced apart to allow a tyre (2) to be received between the first and second lateral support members (12a, 12b) with the crossbar (11) extending across and being in contact with the envelope surface (3) of the tyre,
• the crossbar (11) is lattice-like and is formed by two or more flat, upright and elongated crossbar elements (16) and two or more connecting elements (17),
• each crossbar element (16) has a longitudinal inner edge (18) on the inner side (13) of the crossbar and a longitudinal outer edge (19) on the outer side (14) of the crossbar,
• the crossbar elements (16) extend in parallel with each other in the longitudinal direction of the crossbar (11) and are spaced apart in the cross-direction of the crossbar,
• empty spaces (21) are provided between the crossbar elements (16), the connecting elements (17) are arranged at a distance from each other in the longitudinal direction of the crossbar (11),
• each connecting element (17) extends across and is fixed to the crossbar elements (16) to act as a spacer between the crossbar elements, and each connecting element (17) is configured to project from the crossbar elements (16) on the outer side (14) of the crossbar (11).
