Herewith are the following drawings showing the arrangement of front axle control with the shock damper carried as far out towards the wheel as possible. N. Sch.4333 } Arrangement. N. Sch.4334 } N. Sch.4335 Front spring rear shackle. N. Sch.4339 Steering and control geometry stress and load tables. To avoid interfering with the steering lock angles, the shock damper is inclined to the chassis centre line in the plan view. To reduce the possibility of flexibility due to the centres of the shock damper and radius rod ball ends being widely separated in the plan view, the radius rod is also inclined in the same way. The steering geometry is the same as now. On N. Sch.4335 we have given some protection to the spring rear anchorage, this being made possible by the small angular movement of the shackle. The loads and stresses have been reduced compared with the original radius rod scheme except in the case of the shock damper shaft bearings, which are loaded by the increased overhang of the ball end. It is quite likely the existing bearings will do, but we are sending a suggestion for the use of needle bearings at this point, should a change be needed. Da.{Bernard Day - Chassis Design} | ||
