A flexible vehicle track section for an endless vehicle track has two parallel spaced track belts mutually connected by transverse bars which also serve for transferring drive power from a vehicle wheel to the track. Each section comprises two juxtaposed moulded track units of rubber or similar material each extending over a substantial number of bars, e.g. having a length about 0.5-2 m or more. The outer side face of the unit pad carries spacingly arranged transverse gripping ribs. Apertures with suitable guide sleeves are provided in the track unit pad between the gripping ribs for mounting the transverse bars on the side face being opposite to the ribs. The transverse bars have wing portions with arcuate convex guide cleats thereon projecting in direction away from the track unit pad. In each unit pad a tension wire cable is embedded in the rubber material in shape of an endless loop extending around the peripheral portion of the unit pad. At the ends of the unit retaining members are provided for connection with corresponding members in an adjacent unit and serving for anchoring portions of the tension cable in the pad. I-shaped connection members between successive units in a track belt are provided having an upper flange portion similar to any of the transverse bars for driving and controlling the track section.

An endless vehicle drive track which comprises at least two transversely spaced parallel track belts, each track belt comprising a plurality of elongate track units which are arranged one after another in the longitudinal direction of the track belt, and transverse connecting members provided between the ends of adjacent track units to connect the track units with one another, each track unit comprising: an integral pad which is made of rubber or similar material and has an inner face and an outer face and is formed at its outer face with a plurality of transversely-extending longitudinally-spaced gripping ribs which are integral with the pad, adjacent ribs defining transversely-extending channels therebetween, the channels of each pad of one belt being aligned with respective channels of the pads of each other belt; first and second transverse retainer members provided at opposite respective ends of the pad and at least partly embedded in the material of the pad said retainer members being connected respectively to the two transverse connecting members provided between the ends of the traCk unit and the two adjacent track units respectively; and an elongate reinforcing cable embedded in the material of the pad and extending through the body of the pad, the cable forming a single, closed, substantially rectangular loop extending around the periphery of the pad and outside the retainer members to be retained thereby against movement in the longitudinal direction of the pad, and the track further comprising a plurality of transversely-extending longitudinally-spaced drive bars connecting the belts together, each drive bar being disposed at the inner face of a pad of each belt at a position corresponding to a channel defined between two adjacent ribs of a pad of said belt and being secured to each such pad by at least one fastening member which extends through the pad into said channel, there being one drive bar for each channel of said one belt.
