The invention provides a suspension structure and connecting mode of a bridgeless automobile and relates to the technical field of automobile running system structures. The invention discloses the suspension structure and connecting mode of the bridgeless automobile. The suspension structure and connecting mode of the bridgeless automobile comprises the steps of hinging and connecting the upper ends of left and right side suspensions of a frame to form a rotation point; hinging and connecting the lower ends of the left and right side suspensions with left and right side wheel supporting assemblies and one end of a transverse hydraulic supporting stabilizing bar to form rotation points; hinging and connecting the other end of the transverse hydraulic supporting stabilizing bar with a steering knuckle supporting seat assembly on a sub frame to form a rotation point; when the upper part of a vehicle body is inclined to one side under the influence of steering centrifugal force, the bottomof the sub frame can swing to one side reverse to the direction of the centrifugal force; during swinging, the tail end of a steering knuckle extrudes the transverse hydraulic supporting stabilizingbar to retract so that the transverse supporting distance of this side is shortened and the supporting position of this side is lowered; a hinging part on an associated side is enabled to rotate so that the gravity force of the vehicle body is naturally lowered to automatically offset the steering centrifugal force; and therefore, the supporting balance of the gravity centers, on the left and right sides, of the vehicle body is automatically adjusted.
