Concept and model of terrain wheeled tractor with hybrid drive

The article presents construction concept of a tractor with hybrid, diesel-hydraulic and diesel-electric drive meant for the use in livestock holdings. The tractor is enabled to cover short distances with the combustion engine switched off. This solution uses independent engines to propel front and rear axles. This article presents a computer model and simulation results for the project of a hybrid, diesel-electric tractor based on a benchmark machine Fendt 516. Aside from the ability to drive with diesel engine switched off, the proposed solution has additional positive features allowing smooth transition of relation of peripheral speed of the front and rear wheels. It enables to obtain higher tractive powers for various conditions in a broader range than for a traditional solution (with propelling both axles with one engine through different transmission systems and specific difference of peripheral speed of the wheels). The computer model was built on the basis of the benchmark machine.
