Parametric chassis system for vehicles, comprising four suspension elements, incorporating a lateral torsion bar and co-axial damper unit, in a box-module, that allows central location of heavy items, such as batteries

A parametric chassis system for vehicles having a rear suspension, the system comprising:

• a rear subframe for the rear suspension, the rear subframe having a track, a pair of trailing arms, and two pre-fabricated suspension-box-modules connected to the pair of trailing arms, the rear subframe being formed by a pair of two opposed box-panels encasing the two pre-fabricated suspension-box-modules, each suspension-box-module comprising a co-axial damper unit, a base, and a lateral torsion bar, each suspension-box-module enveloping the respective co-axial damper unit and locating a respective one of the two trailing arms through a respective base,
• a track panel forming a spacer connecting the two opposed suspension-box-modules, the track of the rear subframe being defined by a size of the track panel;
• a front subframe having two swivels, two pre-fabricated suspension-box-modules, and two leading arms, the front subframe corresponding to a reversed rear subframe and locating the two leading arms and wheels, the front subframe operable to carry out steering of the wheels through the two swivels;
• two longitudinal panels defining a wheel base of the vehicle and connecting the rear subframe to the front subframe;
• and
• a chassis having four corners, the four suspension-box-modules of the front subframe and the rear subframe being located on a respective one of the four corners of the chassis, the chassis in a fully active/adaptive mode being operable to apply asymmetric steering characteristics, being controlled electronically without mechanical connection, and providing vehicle control of ride-height, body-roll and dynamic handling by ensuring verticality of the wheels to a given degree.
