VEHICLE SELF-PROPELLED CHASSIS Russian patent published in 1995 - IPC

FIELD: automotive industry; self-propelled chassis of all-wheel drive vehicles with 4 x 4 wheel arrangement. SUBSTANCE: self-propelled chassis has frame 1, suspension support 2 mounted in frame corner zones for axial displacement and fixing against turning. Each pair of adjacent supports is arranged in one plane. Fitted on upper ends of supports are single-arm levers 11, 12 and on lower ends of supports running wheels 13 are mounted; chassis has steering linkage with steering rods coupling levers 11 and 12 of adjacent supports 2. Each pair of adjacent supports 2 is arranged at angle relative to each other. Front and rear wheels 13 of chassis have independent steering linkage. Upper single-arm levers 11 are made for displacement in direction of longitudinal axis of supports 2 by means of power drive. Lower single-arm levers 12 are made for displacement in direction of longitudinal axis of supports 2 by means of power drive. Steering rods of linkage can be made both cross tie and longitudinal drag. EFFECT: enlarged operating capabilities. 5 cl, 10 dwg
