Abstract
This paper presents results of analyses of a three-wheeled vehicle with the newly designed steering system. Our design of steering system is intended to be mounted on a tricycle with the electric drivetrain. The standard steering system of a three-wheeled vehicle has disadvantage, that such a vehicle is unstable, when it is curving a curve mainly at higher speeds. It results to a breach of stability form the overturning point of view. The newly designed steering system of a three-wheeled vehicle contributes to increasing its stability. It means that a three-wheeled vehicle with the newly designed steering system is able to pass a curve with a smaller radius at higher speed. The main objectives of analyses presented in this paper is comparison of driving properties of a three-wheeled vehicle with two wheels on a rear axle with the standard steering system and with the newly designed steering system by means of simulation computations, which were carried out in Simpack package.
Highlights
Current consumption of fossil fuels of motor vehicles and the trend of prices related with it with forces car companies to develop more fuel efficient passenger vehicles
This section contains geometrical relationships, which are related to the overturning stability of a three-wheeled vehicle with two wheels on the rear axle, when it is driving in a curve
We have focused our interest on the fact, whether and how our newly designed steering system is able to improve the overturning stability of a three-wheeled vehicle with three wheels on the rear axle
Summary
Current consumption of fossil fuels of motor vehicles and the trend of prices related with it with forces car companies to develop more fuel efficient passenger vehicles. Standard four-wheeled vehicles are designed to accommodate four to six passengers comfortably with sufficient space for their luggage. This design creation limits significant improvements in the fuel efficiency of these vehicles. Two-wheeled vehicles such as bicycles, mopeds and motorcycles are extremely fuel efficient These two-wheeled vehicles are primary designed as single passenger vehicles with limited luggage compartment. Electric motor drive of vehicles is already applied in several areas of passenger transport [1, 14] and three-wheeled vehicles popularize These facts result to various design of lower-category urban cars with three wheels
