THE TRACTION MECHANICS OF A BULLDOZER WITH PNEUMATIC PROPULSION SCHEME 44 AND BLOCKED ACTUATOR IN THE DEVELOPMENT OF SOIL
The task of the work is to assess the traction capabilities of a wheeled bulldozer when digging the soil in connection with the specifics of its pneumatic-wheeled propulsion and drive of the driving wheels, since publications on this topic are not complete enough. And for this it is necessary, first of all, to further highlight some issues of traction mechanics of these machines, using the material developed by the authors. Due to the complexity of solving all the problems of traction mechanics of a wheeled bulldozer purely analytical way in the work applied analytical-graphical method, which allowed some traction indicators to Express through others, using their graphical dependencies, built on analytical formulas through the General third indicators, by their further exclusion. The object of research is a bulldozer having a pneumatic wheel drive with a wheel scheme 44 and a blocked drive them. The process of functioning of the bulldozer is considered. Traction mechanics of the bulldozer including questions of statics, kinematics, dynamics and management of process of development of soil taking into account specifics of work of its pneumocycle mover is investigated.
