STUDY OF FUNCTIONING CONDITIONS OF WHEEL VEHICLES, INCREASE OF THEIR EFFECTIVENESS IN FARMING

There the study object is T-25A tractor which was equipped by the quick-detachable devices against sliding. The paper purpose is to increase the use effectiveness of wheel vehicles on the basis of improvement of functional properties of propeller on the soils of low bearing strength by application of detachable devices against sliding, which allow to install them on drive wheels easily and fast, to disassemble them under service conditions. The determination methods of traction-grip properties of propeller, of optimum dimensions of detachable grousers on the wheel depending on the propeller dimensions and on the soil properties have been developed. The optimization simulator of grouser number on the drive wheel of vehicle has been substantiated. The program which realizes the main calculations by computer has been developed. The set of substantiated characteristics of grousers of detachable device against sliding has been developed; their application in farming will provided for the rise of crosscountry capability and of output of vehicle. The detachable device against sliding for the wheel tractors form 0,6-1,4 class has been introduced in number of farms of TatarstanAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
