The forward movement is achieved by ensuring that the springs allow limited longitudinal travel of the axle and by positioning leading radius rods each to thrust the associated wheel forwardly when it experiences bump conditions. | InventorApplicationNo. 05/604691 filed on 08/14/1975US Classes:280/86.75, Alignment adjustment267/242, Including adjustment for spring loading280/124.106, Antiroll or antisway280/124.157, Fluidic suspension280/124.175, Connection detail280/124.177, Elastomeric spring280/124.179Coil springExaminersPrimary: Goodman, PhilipAttorney, Agent or FirmUS Patent References1097353, 2264174, 2626144, 3013794Foreign Application Priority Data1974-08-16 AU |
