Abstract:
A chassis system (47), (53) and suspension module for vehicles comprising a subsystem for each wheel, incorporating a lateral torsion bar (1) and co-axial enveloping damper unit (9), featuring active-adaptive suspension characteristics. Four pre-fabricated suspension modules are situated inside respective box-structures (20), connected via wheelbase (39) and track (38) members, allowing the storage of heavy elements (such as batteries or fuel-cells) make up the chassis. The chassis being robust and self-carrying is enhanced, using upper body members (45), in terms of structural rigidity, for a given wheelbase, achieveing high impact-energy absorbtion. The suspension arms (5) can incorporate upper and lower members (42), (43), articulation, connect internally or externaly to the suspension module, and transmit drive and brake forces to the wheels. The suspension module, the box-structure, the torsion-bar/damper unit (17), drive (48) and transmission (54) unit, suspension arm and steer module, featuring asymmetrical steer characteristics, can be reproduced on each corner of the chassis, featuring electronic control without mechanical connection (steer by wire), constituting the chassis of the vehicle (53).
