Concept analysis of front wheel drive systems in future trucks

Abstract [en]

A new type of heavy truck is under development at Volvo with the purpose to create a versatile vehicle that can improve on-road and off-road transports. If a traditional mechanical transmission on the front axle can be replaced by a lighter transmission a bigger pay load will be possible. During on-road transports all wheel drive is seldom needed, hence would a front axle propulsion system that is easily engage able/disengage able be beneficial because of decreased fuel consumption. The target of this master thesis work has been to map, develop and compare current front axle propulsion systems for a heavy truck. Technologies in focus have mainly been hydraulic, electrical and mechanical. A key component in a non mechanical transmission is where the power from the combustion engine is to be taken out. Because of that, different concepts of implementing a new power take-off adapted for a hydraulic pump installation has been carried out. For a prototype fleet ready in 2008, a comparison of different hauler/trailer concepts with the goal to find the best solution regarding load capacity, tracking performance and ground shearing was done as a last part of the thesis work.
