CATERPILLAR PROPULSION SYSTEM AND VEHICLE BASED ON SAID SYSTEM

摘要

A caterpillar propulsion system is proposed in which a caterpillar chain (15) consists of track links (17) which are coupled to one another so as to articulate via axis elements (18, 19) and provided with a device for fixing each track link at an angle to the adjacent track link before they are placed on the ground. The fixing device takes the form of plates (20) and stop elements (21) which co-operate with them. On the rear element (12) of the housing is mounted a device for unfixing the track links (17) in the form of disks (30) which co-operate with the flexible plates (21).
