FIELD: transportation.SUBSTANCE: chassis for moving over various support surfaces contains wheel-step movers, each of which consists of three supports fixed on a common shaft symmetrically relative to the axis of shaft rotation and inclined to each other, forming the lateral edges of an imaginary pyramid. The shaft is located at an angle to the supporting surface in such a way that the support surface is not touched by more than two supports from each wheel-step mover at the same time. The shaft is fixed with the possibility of lateral movements and is kinematically connected with the vibration compensator fixed to the chassis.EFFECT: increased reliability and speed of movement, increased passableness due to increase of clearance.14 cl, 6 dwg
