Practical Procedures for Designing and Analyzing a Tandem Truck Driveline

Procedures for designing and evaluating a tandem truck driveline are presented here in a form that requires only basic algebra and trigonometry for using the graphs, illustrations, and tables. Phasing of a two joint driveline with the joints in two different planes, angular velocity relationship, and prediction of universal joint bearing life are all expressed in simple equations. Important design considerations are presented for the spline, tube and cross. Stress formulas and fatigue curves that provide technical assistance to a designer for these components are illustrated and explained.
