Abstract
A steering system has a steering wheel and steered vehicle wheels which are normally connected only controlwise by a control system, with the steering wheel actuating a steering angle setpoint generator and with the steered vehicle wheels adjusting a steering angle actual value generator so that the control system can actuate a motorized steering control assembly in accordance with a setpoint-actual value comparison of the steering angle during control of the steered vehicle wheels by steering. Axial displaceability of the steering wheel is provided so that stable mounting prevents vibrations of the steering wheel and the feedback effects on the steering angle setpoint generator originating therefrom.
Claims21
Steering system for motor vehicles comprising:
- a steering wheel that can be operated by the driver,
- a steering assembly for using a motor to adjust the steering of steered vehicle wheels,
- a steering angle setpoint generator actuated by the steering wheel,
- a steering angle actual value generator actuated by the steered vehicle wheels,
- a control system that operates the steering assembly as a function of a comparison of the setpoint and actual value of the steering angle, and
- a manual force control device which, in correlation with forces that develop between the steered vehicle wheels and the steering assembly, produces a restoring force on the steering handle as well as a control travel of the steering handle correlated with changes in the steering angle of the steered vehicle wheels,
- wherein the manual force controller is connected drivewise with the steering wheel by an axially stationary shaft part, said part being axially displaceably and nonrotatably connected with another shaft part that is mounted axially and radially in a jacket tube at an end facing the steering wheel and is axially displaceably guided in the jacket tube in a relatively stationary housing part and is held with substantially zero play by spring clamping of said jacket tube.
A steering system assembly comprising:
- a steering wheel,
- a hydroelectric control system operable to control steered vehicle wheels, and
- a manual force controller operable to provide steering control forces to the steering wheel,
- wherein the manual force controller is connected drivewise with the steering wheel by an axially stationary shaft part, said part being axially displaceably and nonrotatably connected with another shaft part that is mounted axially and radially in a jacket tube at its end facing the steering wheel and is axially displaceably guided in the jacket tube in a relatively stationary housing part and is held with substantially zero play by spring clamping on said jacket tube.
