Abstract

The invention relates to a test bench for hybrid four-wheel drive tractors. The test bench comprises a rack control device, an inertia simulator, a power output loading device, front axle dynamometers and rear axle dynamometers. Research and development are done according to the special requirement for hybrid powder, a test debugging environment the same as that for a hybrid tractor is provided for part assemblies of the hybrid tractor, the controllers in the test bench are subjected to data acquisition and control by the rack control device, and performance analysis, data processing and real-time displaying in light, medium and heavy load states of the tractor under the conditions of harrowing, seeding, rotary tillage and ploughing or the transport conditions of normal running, climbing, downhill running and the like are achieved, and a fine test platform is provided for the further study on hybrid tractors.

Description

technical field [0001] The invention relates to a hybrid power four-wheel drive tractor test stand. Background technique [0002] In recent years, the number of domestic tractors has increased year by year, making tractors one of the factors that cannot be ignored in the current environmental pollution and energy consumption problems. With the gradual maturity of hybrid technology, hybrid tractors will soon become an inevitable trend in the development of tractors. Research on hybrid tractors has been carried out in China, but due to the severe lack of various experimental equipment, the research is still in its infancy, and the development is slow, which seriously restricts the research on various performances, design analysis methods and control systems of hybrid tractors. [0003] In order to carry out the test and debugging of each component assembly of the hybrid tractor in the same environment as the whole vehicle, the research and development of the whole machine, the...
