The suspension comprises a central driven shaft with each end connected to an axle through a universal joint, the outer ends of the axles are enclosed by a collar member which allows the axles to rotate therein, a torsion bar is connected between each collar member and the central frame member to prevent horizontal displacement of the axles, and two resilient members in the form of hydraulic shock absorber and coil spring combinations are connected between the collar members and the central frame to allow resistive vertical movement of each axle independent of the other.
