Engine Power

The stability of motion and handling, mobility and fuel consumption of an all-wheel drive automobile depend on how the engine power is distributed among the front and rear axles and then between the left and right wheels of each axle. This power distribution is dependent on the properties of the driveline system and its power-dividing units (PDU) located between the drive axles and between the wheels of each drive axle. This paper presents a generalized driveline model and a computer algorithm. This model provides a way to model the power distribution among the four drive wheels of the automobile when using any of the existent passive power dividing units: open differentials, locked units, limited slip differentials with different locker properties and other mechanisms. The computer computational algorithm allows transferring each PDU from one state to another as a function of i) changes in the driving conditions, ii) the properties of the power-dividing unit, iii) variations in the mass and geometry parameters of the vehicle, and iv) its other systems (tires, suspension, transmission and engine). Using this generalized model and the computational algorithm in a MATLAB/Simulink environment, a program package is developed to embed into a computer model (user interested in investigating the effect of various driveline types on the dynamics of an all-wheel drive automobile). The paper presents examples of utilization of the above program package in investigating the features of curvilinear motion of an all-wheel drive automobile.

Theoretical Considerations

This article presents the results of analysis of power distribution in an electric vehicle independent all-wheel drive. The utilized method of velocity distribution takes into account the change in the motion resistance occurring on particular wheel. Moreover, the method of determining the change of vertical loads on traction wheels is also described. Theoretical considerations were verified on a dedicated laboratory stand that allows to perform real time simulation for analysed powertrain structure. The results of two different scenarios of vehicle driving in curvilinear motion are presented.

The Impact

In recent years, leading automotive companies have been developing various wheel power management systems for controlling power distribution among the driving wheels of all-wheel drive vehicles. Such systems being successors of tank turn/steer mechanisms have inspired new designs of wheeled vehicle driveline systems. Modern wheel power management systems usually consist of planetary transmissions with controllable clutches. The proposed paper analyzes kinematics and dynamics of main types of these systems and then the impact of the systems on the vehicle energy loading, mechanical power loss and, finally, on vehicle energy efficiency. Results of analytical research of double differentials, and open differential with three-link planetary rows are presented in comparison with traditional open differential. Conditions for providing improved energy (i.e. fuel efficiency) are formulated and then analytical representation is given to mathematically link parameters of the wheel power management systems with vehicle tread and minimal turn radius. Hence, a design engineer can assign the optimal parameters of a wheel power management system that provides improved vehicle energy/fuel efficiency.

Modification Of The Surface

The attack, on the surface of a polymer, by the atomic, molecular and ionic species that are created in a low pressure electrical discharge in a gas is interesting because: 1) significant interior morphological features may be revealed, 2) dielectric breakdown of polymeric insulation on high voltage power distribution lines involves the attack on the polymer of such species created in a corona discharge, 3) adhesive bonds formed between polymer surfaces subjected to such SDecies are much stronger than bonds between untreated surfaces, 4) the chemical modification of the surface creates a reactive surface to which a thin layer of another polymer may be bonded by glow discharge polymerization.
