A new omnidirectional track drive system for off-road vehicles



The purpose of this paper is to present a new drive technology for construction machines. The concept is based on Mecanum wheels (passive rollers) mounted on a track. This concept was evaluated by two demonstrators of considerable different sizes. The first demonstrator weights 100 kg and have a load capacity of 80 kg. It is driven by battery-powered servo-motors and controlled by a micro-controller. The second demonstrator weights 4 tons and may carry 6 tons. It is powered by a diesel motor, which delivers energy for a hydraulic system controlled by a programmable logic controller.
The paper will present design and functionality of the two demonstrators as well as their evaluation by driving test cases. As a result, the benefits and drawbacks of this omnidirectional track drive system will be derived and possible application fields will be discussed.

Host city and venue - Vienna

Vienna (Wien) is the federal capital and largest city of Austria, and one of the nine states of Austria. Vienna is Austria's primate city, with a population of about 1.9 million (2.6 million within the metropolitan area, nearly one third of Austria's population), and its cultural, economic, and political centre.
