Description
Technical Field
The invention relates to an adjustable steering column for a motor vehicle.
Background
Typically, the steering column in a passenger car can be adjusted in height and length manually or electrically. In particular, the longitudinal adjustment is often implemented as a telescopic device between a housing, which performs a pivoting movement for the height adjustment, and a telescopic tube (often referred to as a crash tube or guide tube).
Furthermore, some steering columns have a so-called easy entry function, which enables the steering column body of the steering column to be retracted to a depth allowed by the adjustment range of the steering column. The adjustment range of the steering column typically has a stroke of 25mm to 35 mm.
DE 102008060225B 4 discloses an adjustable steering column for a motor vehicle, which steering column has a steering column body for mounting a rotatable steering shaft, a clamping mechanism for achieving a continuously variable adjustability of the steering shaft in the longitudinal direction of the steering column body, and an energy-absorbing mechanism for the energy-consuming displacement of the steering shaft in an accident.
However, in the context of autonomous driving operation using a vehicle, it is desirable to allow a greater adjustment range of the steering column so that the steering column and the steering device mounted thereon can sink to the greatest extent into the dashboard or inner lining of the vehicle in the autonomous driving operation of the vehicle.
The conventional steering column is usually adjusted by a spindle drive coupled to the electric machine, wherein a spindle nut of the spindle drive is coupled to an energy absorption element which in turn has a direct connection to the crash tube.
It is therefore the object of the present invention to provide an improved adjustable steering column for a motor vehicle, which enables a wider adjustability of the telescopic mechanism relative to the steering column body.
This object is achieved by an adjustable steering column for a motor vehicle having the features of claim 1.
Disclosure of Invention
The invention provides an adjustable steering column for a motor vehicle, comprising a steering column body for supporting a rotatable steering shaft, a sleeve arranged in a longitudinally movable manner in an opening of the steering column body, and a crash tube arranged in a longitudinally movable manner in an opening of the sleeve.
The adjustable steering column further includes a plurality of first guide assemblies guiding the sleeve in the steering column body for moving the sleeve in the axial direction of the steering column body and a plurality of second guide assemblies guiding the crash tube in the sleeve for moving the crash tube in the axial direction of the steering column body.
The adjustable steering column further comprises a drive for adjusting the steering column and a transmission mechanism configured to convert an axial movement of the sleeve into an axial movement of the crash tube.
The invention is based on the idea of providing a telescopic mechanism consisting of a sleeve and a crash tube, which is designed to convert an axial movement of the sleeve into an axial movement of the crash tube, by providing a transmission mechanism by which the sleeve and the crash tube are coupled. The adjustment path of the steering column is therefore advantageously larger.
Furthermore, due to the joint actuating movement of the sleeve and the crash tube, the actuating speed is increased, which is advantageous for the intended use in the area of autonomous driving operation, since the change from manual driving operation to autonomous driving operation and vice versa can thus be carried out more quickly.
Advantageous embodiments and developments emerge from the dependent claims and from the description with reference to the figures.
According to a preferred refinement, it is provided that the gear mechanism is designed as a rack gear, wherein the gear mechanism has a first rack arranged axially in the opening of the steering column body, a second rack arranged adjacent to the first rack on the outer circumference of the crash tube, and a toothed wheel which meshes with the first rack and the second rack.
By providing a transmission mechanism, a mechanically stable connection can thus be provided in an advantageous manner between the steering column body and the crash tube, while at the same time the crash tube and the sleeve can be telescoped.
According to a further preferred refinement, it is provided that the gearwheel has a central axle shaft (Achswelle), wherein a first axle shaft section which projects on a first side of the gearwheel is mounted in a first needle bearing (nadelager) which is accommodated in the sleeve, and wherein a second axle shaft section which projects on a second side of the gearwheel is mounted in a second needle bearing which is accommodated in the sleeve.
Since the pinion is accommodated in the first and second needle bearings, the pinion is supported in the sleeve when moving along the first and second racks. The gear wheel is therefore advantageously set in motion during the axial movement of the sleeve caused by the spindle drive.
Thus, by the rolling of the gear wheel on the first and second toothed rack, a torque transmission from the bushing via the gear wheel onto the crash tube is achieved, so that the crash tube likewise performs an axial movement.
According to another preferred refinement, it is provided that the gear mechanism has a gear ratio of 2: a transmission ratio of 1, wherein the transmission is configured to convert an axial adjustment of the first length of the sleeve into an axial adjustment of the second length of the crash tube, wherein the second length has a value which is twice the value of the first length, i.e. the crash tube has an adjustment path which is twice the adjustment path of the sleeve.
Advantageously, the transmission ratio is obtained by rolling of the gear wheels on the toothed sections of the first and second toothed racks, wherein the resulting axial movement of the crash tube corresponds to a double adjustment path of the sleeve.
According to a further preferred development, it is provided that the first and second toothed racks have a constant toothing along their rolling curve. The transmission mechanism can therefore be provided cost-effectively by simple structural means.
According to a further preferred development, it is provided that the first toothed rack is fixed in the opening of the steering column body by means of a first fixing means, in particular a screw, and wherein the second toothed rack is fixed, in particular welded, to the outer circumference of the crash tube. In an advantageous manner, therefore, there is a simple assembly of the first and second toothed racks onto the respective fastening assembly of the steering column.
According to a further preferred development, it is provided that the steering column body has an axial recess for receiving the first toothed rack.
The first toothed rack can thus be arranged space-effectively in the recess of the steering column body. The required overall height of the bushing is thereby advantageously reduced and the total overall height of the steering column that can be adjusted is therefore necessarily reduced.
According to a further preferred refinement, it is provided that the drive has an electric motor and a spindle drive connected to the electric motor, wherein a spindle nut of the spindle drive has a rigid connection to a belt, in particular a steel belt, which is fastened to the sleeve, wherein the spindle nut is designed for axially adjusting the sleeve by a movement along the spindle.
The spindle nut of the spindle drive is thus advantageously adjusted by its connection to the belt by the sleeve, which in turn is connected to the crash tube by the drive.
According to a further preferred development, it is provided that the axial adjustment range of the steering column from the first driving position to the second driving position is at least 70mm, preferably at least 100 mm. The telescopic mechanism of the steering column thus advantageously achieves full sinking of the steering wheel or steering device in the dashboard or lining of the motor vehicle in the second driving position.
According to a further preferred development, it is provided that the adjustment speed of the steering column, in particular of the combination of the sleeve and the crash tube, is between 10 and 100mm/s, preferably between 40 and 100mm/s, particularly preferably between 70 and 100 mm/s. In comparison with conventional solutions, therefore, an increased adjustment speed of the steering column can be advantageously achieved, which is advantageous for the intended use in the autonomous driving range of the motor vehicle, since a change between manual driving operation and autonomous driving operation and vice versa can thereby be effected rapidly.
According to a further preferred refinement, it is provided that the first guide arrangements have a section which is formed substantially concavely on the inner circumference of the column body, a section which is formed substantially concavely on the outer circumference of the sleeve, and a plurality of balls which are arranged in cavities between the section which is formed substantially concavely on the inner circumference of the column body and the section which is formed substantially concavely on the outer circumference of the sleeve.
Since a tube-in-tube telescopic tube mechanism is provided, which comprises a sleeve longitudinally movably arranged in the opening of the steering column body and a crash tube longitudinally movably arranged in the opening of the sleeve, which is supported by means of a respective guide assembly ball, a compact adjustment mechanism for adjusting the steering column can advantageously be provided.
According to a further preferred refinement, it is provided that the second guide assemblies have a section which is formed substantially concavely on the inner circumference of the sleeve, a section which is formed substantially concavely on the outer circumference of the crash tube, and a plurality of balls which are arranged in the hollow space between the section which is formed substantially concavely on the inner circumference of the sleeve and the section which is formed substantially concavely on the outer circumference of the crash tube.
In addition to an advantageously compact adjusting mechanism for adjusting the steering column, this arrangement has the advantage that it can be installed in a simple manner in the steering column. Furthermore, a guide assembly with a plurality of balls has the advantage of low friction and low noise adjustability of the tube.
The described embodiments and modifications can be combined with one another as desired.
Other possible embodiments, improvements and embodiments of the invention also include combinations of features of the invention not explicitly mentioned above or below in connection with the examples.
