Example apparatuses and techniques are disclosed for towing tracked vehicles at high speeds without various deficiencies and for allowing a vehicle to be configured to extend supplemental wheels from a storage configuration into a ground support configuration in which the vehicle is able to make use of the supplemental wheels for additional ground support.

This tracked vehicle for the transportation of at least one reduced mobility person comprises an endless track drive (10) on each side of a passenger compartment. Each endless track drive comprises an endless belt (102A-102D), an electric motor connected to a drive pulley (108) in engagement with the belt, an idle pulley; a sub-frame (110) supporting the drive pulley and the idle pulley, respectively around a first rotation axis (Y108) and a second rotation axis (Y112) parallel to the first rotation axis; and a suspension system. The suspension system includes two articulated arms (116, 120) mounted on the sub-frame (110) with a possibility of rotation around a first articulation axis (Y116) and a second articulation axis (Y120) parallel to the first and second rotation axes (Y108, Y112), each articulated arm being equipped with several rollers (118, 119) in permanent contact with an upper surface (S102) of a lower strand (102B) of the endless belt, between the two pulleys (108, 112), and with a set of teeth (1166, 1206) in meshing engagement with the set of teeth of the other arm. The suspension system also includes elastic means for biasing (E1) the sets of teeth (1166, 1206) of the two articulated arms (116, 120) toward the lower strand (102B) of the endless belt.

A track kit for a vehicle (2), having two track assemblies (1,1′), each track assembly having an endless track (5), a front idler wheel (8), an intermediate support member (6) with at least one track engaging element (7), a rear idler wheel (9), a drive wheel (10), at least one swing arm (11,12) and a shock absorber connecting assembly (13,14), wherein the endless track (5) has an external side featuring ground lugs (15) for ground engagement and an internal side featuring drive lugs (16) for engagement with the drive wheel (10), and the internal side is circumferentially trained around and in contact with the front idler wheel (8).

The invention relates to a welding technical field and provides a crawling welding robot. The crawling welding robot includes a vehicle chassis and two crawler wheels connected to two opposite sides of the vehicle chassis, respectively, wheel carriers of two crawler wheels are movably connected with the vehicle chassis. In this way, when the crawling welding robot moves on a non-planar surface for welding, the two crawler wheels can freely adjust its posture relative to the vehicle chassis to adapt to the surface for welding and improve a degree of fit between the two crawler wheels and the surface for welding, making the moving direction of the crawling welding robot easier to be controlled and reducing a probability of the crawling welding robot slipping or falling from the surface for welding.

The invention relates to a tracked vehicle comprising a vehicle body and a track assembly pair. Said track assembly pair is arranged to suspendedly support said vehicle body allowing relative movement between said vehicle body and each track assembly (21) of said track assembly pair. Each track assembly (21) comprises a track support beam (22) configured to support a plurality of road wheels (23, 23a), a drive wheel (24), and a motor (110) for operating said drive wheel (24), an endless track (25) being disposed around said road wheels (23, 23a) and drive wheel (24). Said motor (110) is fixedly arranged to said track support beam (22). Said motor (110) is arranged in connection to the drive wheel (24) such that a motor axle essentially coaxially coincides with a centre axis (Z) of the drive wheel (24).
