The invention relates to structural components of vehicles, and more particularly to the suspension of both conventional and special vehicles, such as ambulances, baby carriages and wheelchairs. The suspension comprises a quadrangular frame with a pair of arms attached thereto, where the ends of said arms are configured to be connected to the hubs of the respective wheels, and the suspension of the present invention comprises two pairs of arms—a pair of identical transverse arms and a pair of identical longitudinal arms with the ends of the longitudinal arms configured to be connected to the hubs of the respective wheels, wherein each arm is rotatably attached by its central zone to the central portion of the corresponding side of a quadrangular frame through rubber-metal joint, wherein the arms contact surfaces are cylindrical, they are adapted for mechanical coupling of arms to each other and are oriented as follows: longitudinal left and right arms have their contact surfaces oriented upwards, while transverse front and back arms have their contact surfaces oriented downwards, contact surfaces of each arm are tangent to the plane extending through the axis of rotation of the arm and are located on one side of it, while each side of the quadrangular frame rests upon the hubs of two wheels through the corresponding arm. Each transverse and longitudinal arm is made as a pair of arms spaced apart and connected by at least one connecting rod, and each such spaced arm has the form of a parallelogram. The invention is based on the objective to provide the suspension, which is more reliable due to lower level of mechanical stresses in the suspension mechanisms, which results from creation of the conditions where the function of the mechanism for changing the direction of rotation is performed by a transverse arm having a length equal to the width of the suspension.
