Suspension and automobile

The invention relates to a suspension and an automobile. The suspension comprises a first swing arm and a second swing arm which are rotationally connected through a rotating shaft; the first corresponding ends of the first swing arm and the second swing arm are connected to a knuckle separately, the second ends are each provided with a connecting point rotationally connected with the bottom of achassis, at least one of the second ends of the first swing arm and the second swing arm can slide in the transverse direction relative to the bottom of the chassis, the distances between the rotatingshaft and the connection points of the first swing arm and the second swing arm are equal, and the distances between the Z-direction plane where the axis of the rotating shaft is located and the connecting points of the first swing arm and the second swing arm are equal. On the condition that wheels bounce or wheel loads of left and right wheels are different due to steering, the first swing armand the second swing arm ar
