STEP FOR VEHICLE

摘要

FIELD: transport.SUBSTANCE: step for vehicle contains "?"-shaped flat-topped frame located in the area of door opening of vehicle cabin and accommodated under fixed step. Transversally oriented portion of "?"-shaped frame forms footboard. Free ends of vertically oriented frame portions are linked with assembly for turning frame into up and down position. Turning assembly is made as two located in parallel irregular parallelograms. Longitudinally oriented rods of parallelograms are pivotally linked with vertically oriented portions of "?"-shaped frame and vehicle frame. Length of upper rods exceeds the length of lower rods of these mechanisms. Lower rods of both parallelograms are interconnected by common crossmember. Power hydraulic cylinder is pivotally connected with crossmember and with vehicle frame. Knuckle pivots of parallelogram mechanism longitudinal arms and articulation joint of hydraulic cylinder with vehicle's frame are parallel to "?"-shaped frame and located tier-by-tier in vehicle's frame niche under fixed step.EFFECT: better step operation conditions.5 dwg
