Integration of Component Design for a 170 Ton Off-Highway Truck 770741

The purpose of this paper was to explain the design of the components of the Euclid 170 ton capacity off-highway rear dump truck. The unique aspects of this Euclid design flowed from a threefold perspective: 1. box-section frame construction; 2. liquid spring suspension; 3. horizontal body-side stiffeners.
Since overall vehicle performance and durability were dependent on the harmony which must be developed between major components, particular emphasis was given to an examination of the interrelationships of suspension, frame, and body.
The vehicular characteristics indicated that the suspension system with liquid springs, while yielding a good ride also played an important role in minimizing frame and body distress. In addition, good suspension would not be possible without the proper geometrical orientation the frame design afforded. Finally, loading and haulage were seen to be dependent not only upon the body in which the load is contained, but also upon the suspension which absorbed the input shocks and the frame which eventually supported both body and load.
