Abstract


The influence of the hydraulic machine control parameter in the braking process of a wheeled tractor with a GMT is established. The relationship between the form of the change in the control parameter of the HMG hydrostatic machine and the kinematic, power and energy indicators of the wheeled tractor during braking is determined. The expediency of using the curved shape of the hydraulic control parameter change during braking due to the more effective intensity of the change is proved, which leads to a decrease in the braking and braking distances. The main disadvantage of this research is the need to confirm by experimental tests, obtained theoretically the results.

The article presents a dynamic model of a wheeled tractor with a mathematical description of engine operation, GMT, interaction of wheels with a supporting surface, makes theoretical calculations more approximate to the experimental one.

Making the characteristic evaluation results obtained when implementing a curved, linear and convex shapes of the hydraulic control parameter changes in the HMG should be noted that when compared linear with convex and linear with curved, there are:

– reduction (for linear with curved) of braking time by 11.4 % and an increase (linear with convex) 3.8 %;

– decrease (for linear with curved) of braking distance by 23.3 % and an increase (linear with convex) by 21.7 %.

Comparing the qualitative results (calculation of the area) during the tractor braking, using the linear form of the change with a convex-curved shape of the change in the hydraulic machine control parameter, let’s observe:

– curved with linear: a reduction in the HMG efficiency by 9.3 %, a decrease in the GMT efficiency by 8.7 %, a decrease in the power consumption by 43 %;

– convex with linear: an increase in the HMG efficiency by 11.1 %, an increase in GMT efficiency by 7.4 %, an increase in the power consumption by 50.6 %.

These observations indicate that using the curved shape of the hydraulic control parameter for the tractor KhTZ-21021 during braking, the power losses in the HMG hydraulic link are increasing that is directly related to the efficiency of the braking of the tractor.
