The present invention relates to a vehicle and a method for improving the roll characteristics of a vehicle. The vehicle includes an axle, a sprung mass, a first control arm, a second control arm, a third control arm, a first pivotable joint, a second pivotable joint, a third pivotable joint, and a fourth pivotable joint. The torsional stiffness of the first control arm, the second control arm, the first pivotable joint, the second pivotable joint, the third pivotable joint, and the fourth pivotable joint are substantially equal to or greater than the torsional stiffness of the axle, whereby the axle bends and twists during a sprung mass roll event in order to limit an amount of roll.

Vehicle with a four bar link suspension system provided with improved roll characteristics

A suspension arrangement for interconnecting a frame and an axle in a vehicle includes a control arm having an upper beam and a lower beam, each beam having a first end and a second end, the first end of each beam being pivotally connectable to a vehicle frame at a common pivot point, and the second end of each beam being connected to a bushing arrangement mountable to the vehicle axle, the bushing arrangement having an upper portion connected to the upper beam and a lower portion connected to the lower beam.

Twist beam suspension with dual beam control arm

A suspension arrangement for interconnecting a frame and an axle in a vehicle includes a control arm having a first beam and a second beam in parallel, spaced relation, each beam having a first end with a single arm and a second end with an upper arm and a lower arm to define a Y-shape, the first end being pivotally connectable to a vehicle frame, and the second end being connectable to a vehicle axle disposed between the upper and lower arms, and a bushing arrangement mountable to the vehicle axle, the bushing arrangement having an upper portion connecting between the upper arms of the first beam and second beam and a lower portion connecting between the lower arms of the first beam and second beam.
