Tracked vehicle for constructional purposes has spring/hydraulically-loaded support arms for chassis to permit relative movements between lowe vehicle body and chassis

摘要

The vehicle has a lower vehicle body (5) with frame (6) and side chassis (7,8), each with a track (9,10). At least one support arm (30) for each chassis is connected pivoted to the frame, and is charged elastically and positively by an element, with e.g. a helical spring (42) with internal telescopic rod (43) and/or a piston/cylinder unit. The chassis is hinged directly or indirectly to the support arm.
