Abstract
A steering gear for a vehicle includes a linear drive having at least one displacement element, which is displaceable substantially along a vehicle longitudinal axis of the vehicle and which is fastenable to a steering drag link of the vehicle, in which the linear drive is configured to convert a rotational movement of a steering column of the vehicle into a movement of the displacement element substantially along the vehicle longitudinal axis. Also described is a related vehicle having the steering gear, a method for actuating the steering gear, and a method for steering the vehicle.
Claims15
A steering gear for a vehicle, comprising:
- an input shaft having a spindle section;
- a recirculating ball nut, adjacent the spidle section, and having an external toothing;
- an output shaft having a segmented toothing arranged rotationally conjointly thereon, the segmented toothing meshing with the external toothing;
- a steering arm connected rotationally conjointly to the output shaft and movably connected to a steering drag link;
- and
- a linear drive having at least one displacement element, which is displaceable substantially along a vehicle longitudinal axis of the vehicle and which is fastenable to the steering drag link of the vehicle;
- wherein the linear drive is configured to convert a rotational movement of a steering column of the vehicle into a movement of the displacement element substantially along the vehicle longitudinal axis.
A vehicle, comprising:
- a steering column, which is an input shaft:
- a steering drag link;
- and
- a steering gear, which is coupled to the steering column and to the steering drag link;
- wherein the steering gear includes the input shaft, which has a spindle section;
- a recirculating ball nut, adjacent the spidle section, and having an external toothing;
- an output shaft having a segmented toothing arranged rotationally conjointly thereon, the segmented toothing meshing with the external toothing;
- a steering arm connected rotationally conjointly to the output shaft and movably connected to the steering drag link,
- wherein the steering gear includes a linear drive having at least one displacement element, which is displaceable substantially along a vehicle longitudinal axis of the vehicle and which is fastenable to the steering drag link of the vehicle, and
- wherein the linear drive is configured to convert a rotational movement of the steering column of the vehicle into a movement of the displacement element substantially along the vehicle longitudinal axis.
A method for actuating a steering gear, the method comprising:
- reading in a steering signal that represents a steering movement;
- and
- providing a control signal for controlling a drive unit for driving at least one displacement element using the steering signal;
- wherein the steering gear includes the input shaft, which has a spindle section;
- a recirculating ball nut, adjacent the spidle section, and having an external toothing;
- an output shaft having a segmented toothing arranged rotationally conjointly thereon, the segmented toothing meshing with the external toothing;
- a steering arm connected rotationally conjointly to the output shaft and movably connected to the steering drag link,
- wherein the steering gear includes a linear drive having the at least one displacement element, which is displaceable substantially along a vehicle longitudinal axis of the vehicle and which is fastenable to the steering drag link of the vehicle, and
- wherein the linear drive is configured to convert a rotational movement of the steering column of the vehicle into a movement of the displacement element substantially along the vehicle longitudinal axis.
A method for steering a vehicle, the method comprising:
- coupling a steering moment into the steering gear via a steering column, which is an input shaft, wherein the vehicle includes the steering column, a steering drag link and a steering gear coupled to the steering column and to the steering drag link, wherein the steering gear has a linear drive with at least one displacement element which is displaceable substantially along a vehicle longitudinal axis of the vehicle and which is fastenable to the steering drag link;
- and
- converting the steering moment into a movement of the displacement element substantially along the vehicle longitudinal axis by the linear drive;
- wherein the steering gear includes the input shaft, which has a spindle section;
- a recirculating ball nut, adjacent the spidle section, and having an external toothing;
- an output shaft having a segmented toothing arranged rotationally conjointly thereon, the segmented toothing meshing with the external toothing;
- a steering arm connected rotationally conjointly to the output shaft and movably connected to the steering drag link.
