Slip-in Tube Propshafts With Fixed Flanges at Both Ends

Neapco has developed a slip-in-tube propshaft/driveshaft that solves customer requirements for a fixed flange at both the transmission and axle ends. Using fewer components, Neapco slip-in-tube propshafts/driveshafts are lighter and more cost-effective than traditional designs.

Traditional slip-between-center designs typically use a slip yoke and stud yoke welded to the propshaft/driveshaft tube as a slip mechanism. Available in steel or aluminum, Neapco's design uses an innovative spline forming process to integrate the traditional slip mechanism function into the tube itself. The slip-in-tube design uses two mated tubes with formed splines to transmit torque while functioning as a slip mechanism to accommodate suspension travel. Additional features include:

  • Low plunge effort significantly improves NVH performance
  • Telescopes safely in vehicle crash
  • Higher operating speeds than conventional design
  • Highly durable integrated designs allow warranty and cost improvements
