Neapco manufactures and designs single piece propshafts/driveshafts in a variety of configurations — from traditional slip yoke/fixed flange designs to plunging or fixed constant velocity joints and flexible rubber couplings. Neapco single piece propshafts/driveshafts are available in a variety of materials, including steel, aluminum, and metal matrix or carbon composites.
Neapco offers 2- and 3-piece propshaft/driveshaft designs for vehicles with extended wheelbases. Key features of Neapco multi-piece propshafts/driveshafts include a slip function that can be incorporated in a slip-in-tube design, and a center bearing assembly. Neapco uses a unitized design to eliminate or reduce the design barriers found in traditional slip-thru-center bearing designs, including stack-up, run-out, imbalance and spline interface.
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:
