As a circulating ball steering designed electrical power steering system of a motor vehicle

摘要

The present invention relates to a power steering system of a rail-borne motor vehicle, which is designed as a circulating ball steering. In order to increase the variability of the circulating ball steering, is fixed to a steering transmission input to the reduction of steering forces hand a servo motor is arranged, which is formed as an electric motor. This allows a with respect to the steering spindle radially freely selectable position of the servomotor. As a whole, the possibility to design conditions of the motor vehicle, such as, for example, axle configurations or installation space, can be individually and to react to be variable, as a result of which even a very compact and space-saving construction is achieved.
