Definitions
- the present invention relates to a steering gear for a steer-by-wire steering system of a motor vehicle with the features of the preamble of claim 1 and a steer-by-wire steering system with the features of the preamble of claim 8.
- the position of the steered wheels is not directly coupled to the steering input means, for example a steering wheel.
- DE 10 2006 008 911 A1 discloses a steering system for a motor vehicle with a hollow shaft motor, through the hollow shaft of which a rod is guided which can be driven in the longitudinal direction by means of the electric motor and when used in an auxiliary power steering in a region as a rack for engagement with a steering pinion is trained.
- the hollow shaft is rotatably connected to a pulley.
- the belt gear forms an intermediate gear to a rolling element screw gear.
- a steering gear for a steer-by-wire steering system is one
- Motor vehicle having a hollow shaft motor with a housing-fixed stator and a rotatably mounted rotor, which is arranged coaxially to a longitudinal axis and is penetrated by a screw gear, the screw gear comprising a spindle nut arranged coaxially to the longitudinal axis, which is drivingly connected to the rotor and which sits on a spindle which can be displaced along the longitudinal axis by means of the hollow shaft motor, and the pitch angle of the screw transmission is less than 4.5 °, in particular less than 4 ° and particularly preferably less than 3.5 °.
- Torque into an axial force where f is the angle of friction and a is the pitch angle.
- the ball screw is self-locking below a defined value.
- the angle of friction is preferably less than 4.4 ° and greater than 0.1 °.
- the screw gear is a roller screw gear, in particular a ball screw or a roller screw.
- the screw gear is a trapezoidal screw drive. It can be provided that the rotor sits directly on the nut and is connected to it in a rotationally fixed manner. It is advantageous if the rotor coaxially surrounds the nut. However, an intermediate gear can also be provided, which reduces the speed of the hollow shaft motor and connects the rotor to the nut.
- a steer-by-wire steering system for a motor vehicle comprises:
- a feedback actuator which can be acted upon by a driver with a driver request for a steering angle via a steering input device and which outputs a feedback signal to the steering input device in response to the driver request and a driving state of the motor vehicle
- Control unit transmitted, provided, the control unit controls the steering gear to the
- the spindle itself is preferably designed as a steering rod which is connected to tie rods for steering the wheels of the motor vehicle.
- Fig. 2 a longitudinal section through a steering gear with a hollow shaft motor
- a steer-by-wire steering system 1 is shown in FIG. On a steering shaft 2, a rotation angle sensor (not shown) is attached, which one by rotating a steering input means 3, which in the example as a steering wheel
- a feedback actuator 4 is attached to the steering shaft 2, which serves to simulate the repercussions from the roadway 70 on the steering wheel 3 and thus to give the driver feedback on the steering and driving behavior of the vehicle.
- the driver's steering request is based on the one measured by the rotation angle sensor
- the feedback actuator monitor unit transmits the driver's steering request to a control unit 5.
- the feedback actuator monitor unit preferably also takes over the control of the feedback actuator 4.
- the feedback actuator monitor unit can also be formed integrally with the control unit 5.
- the control unit 5 controls in
