Steering system for commercial vehicle, has steering gear and electric drive motor for generating driving torque and servo gear to step down driving torque

摘要

The steering system has a steering gear (203) and an electric drive motor (207) for generating a driving torque and a servo gear (208) to step down the driving torque. A transmission ratio, formed from the quotient of a steering wheel shaft angle and a drive shaft angle over the steering wheel shaft angle varies between 5 and 30, particularly between 10 and 25. The steering gear is formed from a hypoid gear and a pinion gear.
