HEAVY-WEIGHT TRANSPORTATION VEHICLE Russian patent published in 1996 - IPC

FIELD: road building and repair machinery. SUBSTANCE: vehicle has propelling devices in form of supports with pulsed lifting mechanisms. At oscillatory motion of pulsed mechanism inertia mass 10, inertia forces act periodically onto supports 1 and 2, thus providing counter-phase pressing of supports to surface and separating them from the surface. In semiperiod of pressing, housing 5 is moved relative to pressed support by means of longitudinal displacement mechanism 7, and at separating semiperiods, separated support is returned by spring 8 in initial position relative to housing 5. Pressing of supports to surface by inertia forces increases adhesion weight of vehicle and ensures considerable pulling effort at low power consumption. EFFECT: enlarged operating capabilities. 5 dwg
