INFLUENCE OF CONSTRUCTION AND OPERATING FACTORS ON SUPPLY OF MOTION OF ELECTRO-CARS

Abstract

An analysis over of development of electro-cars in Ukraine, the use of that increases and in an agroindustrial complex, is brought in the article, that conditioned by possibility of charging of accumulators in interremovable time and use of unconventional energy sources. Use of electro-cars conditioned by their economy comparatively with traditional cars and less expenses on technical service. Technical perfection of electro-cars shows up the constructions and technologies of their making improved in future. Structural perfection shows up in diminished details, knots and aggregates, because at an electro-car absent combustion engine, system of cooling with a radiator, small box of transmissions, coupling and mechanical transmission, compactness due to simplification of construction of the bearing system, transmission, form of basket and by the even partition of load. Important structural technical description of electro-cars is their economy that is estimated by the specific expense of electric power and supply of motion. In the floor a calculation way is investigate influence of operating factors on the specific expense of electric power and supply of motion. Influence of rate of movement, acceleration, coefficient of resistance to woobling, size of getting up, presence of wind and ambient temperature on the indexes of economy is shown. The brought calculations over show quantitative sizes to influence of operating factors on the economy of electro-cars. Data of calculations can be used for the choice of the modes of motion in exploitation, and also in an educational process at planning of electro-cars.
