Title: Suspension mechanism for four-wheeled vehicle

Abstract: A suspension mechanism for a four-wheeled automotive vehicle body with independently suspended wheels, comprises front and rear pairs of transversely aligned horizontal torsion bars rotatably supported by front and rear parts of the body. The transversely outer ends of these torsion bars are indirectly coupled to the respective wheels, so that these torsion bars undergo torsional displacement when their associated wheels are moved up and down. The transversely inner ends of the front and rear torsion bars are rigidly coupled to front and rear vertical arms the free ends of which are mutually connected by links extending in the front-to-rear direction of the body. One of the front and rear pairs of vertical arms are pivotally connected by a transverse lever pivotally supported at its middle parts by the vehicle body, whereby the diagonally opposite wheels move in the same vertical direction while the transversely opposite wheels move in the opposite vertical directions.
