A variant of kinematic scheme of power shift gearbox with preselected shifting of working and transport speed ranges for the farm crawler 5-6 class tractor equipped with link steel crawlers and reduced maximum transport speed is considered.
A filter-heater intended for setting into regular sedimentation filter in order to increase the effectiveness of diesel fuel purification is presented.
An integrated system of quality control for mechanized works in crop growing is developed. The block schematic diagram and engineering tools for these purposes are described.
A method of optimal aggregation of basic machines (tractors) and working construction equipment is proposed. System analysis, statistic technometry and economic-mathematical computer simulation are fundamental in this methodology.
The influence of planetary muff gear ratio on the rigidity of pneumohydraulic elastic element has been analyzed.
Cogeneration is a highly effective way to convert and produce heat and electric energy. The method of golden section for the theoretical substantiation of optimal operating modes of cogeneration systems is offered for the use.
The processing chain and corresponding machine systems for woody biomass harvesting and fuel chips production from logging residues, low-quality and small-sized wood are examined. The features of these systems are the possibility of full-tree harvesting during principal felling and cleaning cutting.
An automatic two-channel control system of module with electromechanical transmission including power channel and technological channel is offered. Authors have also analyzed the factors that influence on power inputs at the cutting of herbage during the work of a segment-finger mower with electromechanical drive. An algorithm for calculation of resistance by segment-manual mower operation, which takes into account power consumption for the fluctuations of twisting moment and angular speed is given.
Problems of domestic tractor industry state and prospects of its development are considered.
Traffic safety mainly depends on the reliability of metal-ceramic friction materials used in brake gears, the most important vehicle units. The results of friction disk trials tested in actual condition immediately on the assembly are presented.
The general approach to forecasting of optimum values of operational indicators of the agricultural machine-tractor aggregate for the specified operating conditions is considered. As an example of its realization for the concrete unit the balanced system of operational indicators received as a result, their values, optimum levels of loading and use degree are given.
Basic problems related to the forming and standardization of indexes of tractor trailers' brake properties are considered. The shortcoming of normative documentation currently in force are indicated, suggestions on its perfection are given.
The influence of gas-distribution mechanism characteristics on the work indicators of automobiles' and traktors' piston engines was under study. The results of investigations are cited in this article. Relationships between analogs of a working substance speed in flow areas of inlet and outlet valves and a rotation angle of crankshaft are given.
The results of tiller hoe shape optimization are presented. These findings were used for the production of working organs of the subsurface ploughs, allowing to achieve the best soil cultivation.
The influence of active and passive tools of the combined aggregate on soil is considered. Forces necessary for the soil shift and displacement by an active tool at the semiclamped cutting are revealed.
The analytical expressions are received, allowing to define the basic design data parameters of a space-saving settling chamber of the closed pneumoseparator for conditions of its effective functioning at grain cleaning.
Some results of analysis of opportunities to rise a fuel affordability of diesel 6Ch 11/12.5 by regimes of low load or idling by deactivating some cylinders or cycles, named in other words as method of transformation of diesel active volume are presented. This analysis is carried out with the use of experimental universal diesel characteristics, namely fuel specific consumption of diesel, and mathematical simulation of some regimes of diesel operation.
The new art-design look of frame-panel cab system for serial and prospective «Kharkov tractor plant» production is designed.
A digital device for rapid detection of the clutch skidding of traction and transport machines has been developed. The device is designed to augment the wheel power, improve fuel efficiency and lessen the probability of failure by getting of digital information about the skidding at any moment of vehicle operation.
