A suspension of the type having the weight of the vehicle supported by torsion springs. A rigid shaft is disposed longitudinally of the vehicle adjacent each wheel. Three torsion springs are disposed in longitudinally spaced relationship about each shaft and each spring has an annulus of elastomer as the yieldable portion. Each spring has a rigid outer shell received over the elastomer annulus. A rigid arm is attached to the outer shell of the end springs to connect them resiliently in parallel. Additional arms are rigidly cantilevered from each end of each shaft. In one form of the suspension, the free ends of the arms from the shaft are pivotally connected through shackles to the vehicle frame and the free ends of the arms from the springs secured to the wheel axle. In another form of the suspension, the outer shells of the springs are secured to the vehicle frame and the free end of the arms from the shaft pivotally connected to the axle of the wheel. The center spring has the free end of the arm attached to its outer shell secured to the wheel axle in the first-mentioned form and secured to the vehicle frame in the latter form. Adjustment means are provided on the attachment of the center spring arm for preloading the center spring.
