- Abstract
The paper aims to achieve the normalized maneuverability indicators for buses of especially large class (hinge-jointed) possible by appropriate layout schemes and use of controlled (self-installed) wheels of trailer's section (trailer) which drive can be carried by an electric motor located in the trailing section. Furthermore, the electric motor may be pulling for the bus during movement in urban "traffic jams" when movement speed does not exceed 5 m/s. In view of the lateral wheel's abduction of SHZA was determined total resistance power for rolling wheels. In addition there was defined electric motor power that is set in the trailing section of the bus, based on the need to perform the following modes of movement as starting out from place, rectilinear bus motion, motion along a circle and turn the wheels of trailer's section to improve the maneuverability of an articulated bus. Analysis of static stability conditions SHZA at the implementation of tractive force on the axle of the trailer showed that the coefficient of aerodynamic resistance will not affect the value of the critical velocity (not included in the expression of critical speed), and the coefficients of rolling resistance on the first and second axes slightly affect the value of the critical velocity and a critical value of parameter alpha, which determines the amount of tractive effort. However, even under by optimum selected stiffness and selected layout parameters critical speed of the hinge-articulated buses does not exceed 12.5 m/s, those buses requiring special system against assembly.
