Concept Development of Steered Support Axle for 5-axle Off-Road Vehicles
2014 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

In this project, the object for investigation and product development process was the suspension of the extra support axle on Scania AB’s five axle trucks. One question for the thesis was to find out why some customer demands the support axle position to be in front of the driven bogie while others demands position behind. The current suspension of the extra support axles is today air bellows, which result in both advantages and disadvantages compared to mechanical solutions.The project as performed in two phases: investigation phase and product development phase. The results from the investigation phase were used as input to the product development phase. The assignment for the investigation phase was to list principal differences between the alternatives of position of support axles in front of/behind the driven bogie and find out which type of customer demanded which kind of position for the support axle.The product development phase used the output from the investigation phase to improve some principal differences and the result was an innovative concept of a triple bogie. The concept resulted in mechanical load transfer, which also means instant load transfer and correct axle pressure at all times, which gives advantages like decreased wear (on tire, driveline and other components), increased traction and better accessibility in terrain. Other advantages are that the sensitive air bellows does not have to be used (especially mining application), increased tipping stability and modular design for push and tag setup. Scania AB is investigating the possibility to apply for one or more patent on this solution.
