SUSPENSION INTRODUCTION The suspension of BOLT and ZEST are designed in such a way to offer greater passenger comfort. The technological solutions adopted to reach this goal can be summarized as follows: Front suspension geometry with the positioning of the front and rear pivot bushes, have made it possible to contain the effect of vibration caused due to road undulations; also, helps to decouple the effect of acceleration, braking and cornering loads, providing better stability in all driving conditions Twist beam Suspension also referred as Torsion Beam Suspension designed to provide key advantages of both independent suspension and rigid axle suspension. This ‘H’ shaped Semi-independent rear suspension is designed to increase structural rigidity and increase the flexibility of the suspension through improved bushing. Nitrogen gas charged shock absorbers with improved design configuration for better ride and reduced noise levels in the passenger cabin. Vertical orientation of rear Shock absorbers and their placement with respect to the wheel center provides advantage of effective damping. Stiffness and damping characteristics are modified to suit vehicle ride and handling quality. Focus during design of components has always been related to comfort; technical solutions which are more common in premium vehicles such as asymmetric rear lower control arm bushes to minimize impact harshness are adopted. Structural rigidity of suspension Sub-frame increased to produce better vibrational and acoustic isolation inside the passenger cabin.
