Authors: Azarov V. K. , Gayisin S. V. , Kutenev V. F.
Published: April 2022

The paper analyzes issues of vehicle structural safety regulated by international UN rules in order to reduce the number of road accidents and particularly the severity of their consequences. The effectiveness of the UN Rules for reduction of road accidents is analyzed and especially the number of killed and injured in accidents on the roads is studied. There were also considered the issues related to the increasing pollution of the atmosphere of large cities with exhaust gases harmful emissions from road transport even though long-term efforts of manufacturers were made to drastically reduce them to the Euro 6 for Ecology UN Rules number 49 and 83. A comparative analysis of foreign and domestic studies of emissions from wear of tires, brake mechanisms of road transport and road surface was made. The conclusion of a significant increase in pollution of air environment of large cities because of the solid fine particles from wear of tires and road surface was made. The problems of active, passive and environmental safety predetermine the necessity of reconsideration of the concept and strategy of the international and national legislation, for integrated safety of road transport.

Stabilization of the vertical reactions of the road on the wheel when driving automobile on periodic profile
Authors: Ryazantsev V. I. , Balsam Alsalamech
Published: April 2022

For various reasons roads could be in not very good condition. In particular, at the roads could appear the areas with clearly defined periodic profile. The traffic on such road sections may be accompanied by resonance oscillations of the wheels with their separation from the road. This causes a decrease in stability of the vehicle. To combat this phenomenon the new system of active safety of the cat could be applied - stabilization system of the vertical reactions of the road on the wheel when driving on a periodic profile. Such a system to control the vertical reaction uses an execution unit called the actuator. This is the engine in the form of a hydraulic cylinder or linear motor that is included in suspension in the parallel elastic element and shock absorber. The actuator is controlled by a signal generated by the control unit, which receives a signal from the sensor of vertical force that is perceived by a bus or a signal to replace it. The article shows that the linear control system copes with the elimination of separation of wheel from the road, reducing fluctuations in the value of the vertical reaction to 10% of the static load. In the hydraulic control system vertical reaction of road on the wheel may cause the nonlinear relationship of the values of vertical reaction and the force generated by a hydraulic cylinder. The calculations showed the feasibility of stabilizing the vertical reactions in this case. However, this nonlinearity can cause some instability of vibrations of a vertical reaction. Another promising solution to the design of the hydraulic system of stabilization of the vertical reaction to the preservation of its sufficient efficiency is the use of hydraulic cylinders of unilateral action, which simplifies the system and makes it more available for use, even on compact automobiles.
Increasing the efficiency of the catalytic converter
Authors: Solomin V. A , Shabanov A. V , Shabanov A. A , Kiliushnik V. M , Mladenskiy A. V
Published: April 2022

The article deals with the efficiency of the catalytic converter of automobiles in operation with the aim of solving the problem of reducing the pollution of the atmospheric air by the exhaust gases of automobiles. The problem of reducing emissions of harmful substances of vehicles is considered to be one of the main. The article presents calculations of the efficiency of the neutralizer at various operating conditions of the internal combustion engine, and factors influencing the process of oxidation-reduction reactions are determined. It is shown that a small amount of oxygen (О2) to the neutralizer limits the oxidation processes and does not give a good reduction efficiency for CO and CH. At an О2 concentration of 1.7 to 0.75% up to the neutralizer, the efficiency of the oxidation reactions in the neutralizer is maximal. The main requirements for the process of catalyzing harmful emissions and the disadvantages of modern neutralizers are considered. The main contribution to emissions of CO and CH is made by the modes of starting and warming up of engine. This is especially felt in the cycle of "cold tests" of the automobile under the UN Rules No. 83-06. Emissions of hydrocarbons increase proportionally with a decrease in engine temperature. In this regard, new types of neutralizers are provided to ensure the achievement of catalytic reactor activity at a lower temperature than those currently used on automobiles, as well as on-board vehicle diagnostic systems that support the environmental characteristics of vehicles in operation. The reasons for the "aging" of the neutralizer during its operation, the methods for diagnosing the neutralizer for the purpose of assessing its technical condition and on-board monitoring systems are analyzed. The urgency of the task of improving the design of the automobile in terms of limiting toxicity and the system of technical control in operation was noted. Improvement of the environmental control of vehicles is primarily related to the operability of on-board diagnostic systems of the car in operation and the catalytic neutralization system. The normative base of the Russian Federation and the EU in the field of environmental control of motor vehicles in operation is given.
Overview and classification of advanced schemes of multithreaded combined energy transmissions based on their kinematic analysis
Authors: Ryabev A. V.
Published: April 2022

The article deals with the existing and promising modern automotive multithreaded combined energy transmissions, based on the principle of separation of power for the electrical and mechanical streams. These combined energy transmissions due to the presence in their design of continuously variable electric transmission allow obtaining an arbitrary gear ratio from the engine to the wheels, while maintaining high efficiency inherent to manual transmission. It allows to assume that multithreaded combined energy transmissions are promising for use in hybrid vehicles as evidenced by the successful operation of Toyota Prius automobile. The article describes 16 different schemes of electromechanical transmissions. Some of them are actually applied in practice, while others exist only as prototypes or theoretical projects. On the basis of the kinematic analysis, including determination of number of operating modes and degrees of freedom as well as the construction of kinematic plans for different of operating modes the classification of multithreaded combined energy transmissions by type of differential mechanism (mechanical part of transmission) was proposed. There were allocated single-mode and multi-mode multithreaded combined energy transmissions. The last ones were divided into three classes, depending on the method of obtaining different modes: stepped, variable and combined. Moreover, within each class transmissions with differential at input, differential at output with complex power division were identified. This review allows to get acquainted with possibilities of application of multithreaded combined energy transmissions in road transport, to understand its strengths and weaknesses, identify promising areas of application of multithreaded electromechanical transmissions of various types.
