Definitions

  • the present invention relates to an adjustment unit of a steering column of a vehicle and a steer-by-wire steering system with such an adjustment unit.
  • the steering wheel is adjustable in height and length.
  • the steering column housing parts must move relative to one another. This is achieved by a telescopic arrangement of the housing parts. This allows the steering wheel to be brought into a position that is suitable for the driver. Recently there has been a requirement to retract the steering wheel into a stowage position in the dashboard.
  • an adjustment unit of a steering column of a vehicle in which a steering spindle is rotatably mounted about a longitudinal axis and has a casing unit which has at least three casing tubes arranged axially telescopically relative to one another, one of which forms an outer casing tube, in which at least one intermediate casing tube is accommodated, in which an inner casing tube is accommodated, a motor being provided for adjusting the casing unit, the motor being connected to the intermediate casing tube.
  • Such a structure according to the invention makes it possible for the motor to be moved when the jacket unit is pulled out, i.e. when the jacket unit is adjusted, based on the attachment of the motor to the intermediate jacket tube. This has the advantage that a travel path of the adjustment unit can be increased cost-effectively and in a space-saving manner.
  • the motor actuates a spindle.
  • This spindle is used to operate the telescopic extension of the jacket units.
  • the spindle usually limits the travel distance, as for safety reasons it cannot be selected larger than 100mm.
  • travel distances of greater than 100 mm can now advantageously be achieved for the jacket unit.
  • a nut is in operative connection with the spindle and the nut is also arranged in a stationary manner.
  • the spindle is designed in two parts and has an outer spindle and an inner spindle.
  • the outer spindle and the inner spindle can be moved in and out of one another. This results in a telescopic structure of the spindle.
  • the spindle itself can be designed to be short and at the same time enable large travel distances.
  • the spindle can have an external and internal thread.
  • the threads themselves have an opposite pitch.
  • the outer spindle has a right-hand thread on its outer surface and a left-hand thread on its inner surface.
  • the inner spindle has a left-hand thread on its outer surface 13.
  • FIG. 1 shows a schematic representation of an adjustment unit according to the invention according to a first embodiment in the retracted state
  • FIG. 2 shows a schematic representation of an adjustment unit according to the invention according to a first embodiment in the extended state
  • FIG. 3 shows a schematic representation of an adjustment unit according to the invention according to a second embodiment in the retracted state
  • Fig. 4 is a schematic representation of an adjustment unit according to the invention according to a second embodiment in the extended state.
  • Fig. 1 shows a schematic representation of an adjustment unit 1 according to the invention according to a first embodiment in the retracted state.
  • the adjustment unit 1 has a casing unit 2, which has at least three casing tubes arranged axially telescopically relative to one another, one of which forms an outer casing tube 3, in which at least one intermediate casing tube 4 is accommodated, in which an inner casing tube 5 is accommodated.
  • the jacket tubes 3, 4, 5 are adjusted by means of a motor 6, i.e. adjusted from a retracted state (Fig. 1) to an extended state (Fig. 2).
  • the motor 6 itself is connected to the intermediate casing tube 4. It can also be seen that the motor 6 is arranged in the direction of a steering wheel 14.
  • the motor 6 is further connected to a spindle 7, which is also actuated by the motor 6.
  • the spindle 7 serves to operate the telescopic extension of the jacket units 2.
  • the spindle 7 is designed in two parts and has an outer spindle 8 and an inner spindle 9.
  • the outer spindle 8 and the inner spindle 9 are designed in such a way that they can be moved in and out of one another.
  • a nut 10 is operatively connected to the outer spindle 8.
  • the mother 10 itself is also arranged in a stationary manner.
  • the outer spindle 8 has a right-hand thread on its outer surface 11 and a left-hand thread on its inner surface 12.
  • the inner spindle 9 has a left-hand thread on its outer surface 13.
  • the outer spindle 8 is driven by the motor 6, whereby the nut 10 on the external thread moves by the pitch in one direction and the inner spindle 9 moves by the pitch in the other direction (opposite directions) with one revolution. This means that two paths are defined with one spindle.
  • Figure 2 shows the adjustment unit 1 from Figure 1 in the extended state.
  • FIGS 3 to 4 show a further exemplary embodiment of the adjustment unit 1 according to the invention.
  • the same components are designated with the same reference numbers as in the previous figures. The description only focuses on the different training.
