All-terrain hybrid power chassis

Abstract

The invention relates to an all-terrain hybrid power chassis, and belongs to the field of agricultural machinery. The chassis is characterized in that the chassis is in a symmetrical structure, and comprises a trolley body and four motion units with the same structural size, wherein each motion unit comprises a liftable driving wheel mechanism and a track swing arm mechanism; liftable driving wheels are driven by a hub motor; the track swing arm mechanisms are driven by rear wheels; power is provided by a diesel engine; four track swing arms are configured on the inner sides of wheels; and the track swing arm mechanisms can achieve rotation motion of tracks and can swing around central shafts of track driving wheels. The chassis has the characteristics of quick wheel motion, can adjust the lifting heights of the driving wheels, and can adjust a ground clearance; during transverse working in a sloping field, the lifting heights of the driving wheels on the left and right sides can be adjusted, and the levelness of a chassis frame is maintained, so that side turn of working machinery is avoided; and obstacle-crossing and climbing motion in a complicated farmland environment can be achieved by the track swing arms or compound motion of the track swing arms and the driving wheels.

Description

technical field [0001] The invention relates to an all-terrain hybrid power chassis, which relates to the field of agricultural machinery. technical background [0002] my country's hilly and mountainous areas account for about 70% of the total land area, and hilly and mountainous areas have unique natural conditions such as large slopes, small plots, irregular terrain, and narrow farming roads, so that agricultural machinery in mountainous areas not only requires its chassis to be able to adapt to various complex terrains , when working horizontally, it is also necessary to effectively avoid tipping and ensure safe operation. It is also required that the operating machinery can realize long-distance, long-term and heavy-duty operations. At present, wheeled or tracked power chassis are generally used in agricultural machinery in mountainous areas. The wheeled chassis has the advantages of simple structure, high speed and low energy consumption, but it is not suitable for cro...

AI Technical Summary

Problems solved by technology

The wheeled chassis has the advantages of simple structure, high speed and low energy consumption, but it is not suitable for crossing obstacles such as ravines and ridges, and its ability to overcome obstacles is poor; the crawler chassis has high crossing ability and good performance in soft and uneven terrain Environmental adaptability, less damage to soil compaction, but has the disadvantages of high driving resistance and high energy consumption

In recent years, many scholars have researched and developed the wheel-track composite mobile platform, so that it can combine the advantages of wheel and track-type power chassis, but the research and application areas are concentrated on small mobile robots, using batteries as power sources. and limited battery life, not suitable for long-distance, long-term and heavy-duty operations
