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 casing unit and a housing accommodating a spindle and the motor actuating the spindle.
  • Such a structure according to the invention enables the spindle to be used to operate the telescopic extension of the jacket units.
  • the spindle usually limits the travel distance, as for safety reasons it cannot be chosen to be larger than 100mm. Based on the inventive combination of the arrangement of the motor and the use of a short spindle, travel distances of greater than 100 mm can now advantageously be achieved for the jacket unit.
  • the spindle is designed in several parts and has at least one outer spindle, at least one intermediate spindle and at least one inner spindle.
  • the outer spindle, the intermediate 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 motor is preferably in operative connection with the intermediate spindle.
  • the intermediate spindle and/or the inner spindle is designed as a trapezoidal thread spindle.
  • the intermediate spindle which is designed as a trapezoidal spindle, is driven by the motor. This allows a rotational movement to be transmitted.
  • the intermediate spindle moves axially and is connected to the inner spindle by means of a trapezoidal thread connection, which can thereby carry out a corresponding axial movement. This has the advantage that the adjustment speed can be increased due to the trapezoidal thread.
  • the spindle can be designed as a ball screw.
  • the inner spindle is connected to the inner casing tube.
  • An alternative embodiment of the invention provides that the intermediate spindle is rotatably mounted with the outer casing tube.
  • Such structures mean that the motor does not require any axial travel.
  • the spindles enable a defined extension of the guide tubes towards one another
  • 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 is a schematic representation of an adjustment unit according to the invention according to a second embodiment in the retracted 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 jacket unit 2 and a housing 8 accommodating a spindle 7. Furthermore, it can be seen that the motor 6 is arranged in the direction away from a steering wheel 14.
  • the motor 6 also actuates the spindle 7.
  • the spindle 7 serves to actuate the telescopic extension of the jacket units 2.
  • the spindle 7 is designed in several parts and has an outer spindle 9, an intermediate spindle 10 and an inner spindle 11.
  • the outer spindle 9, the intermediate spindle 10 and the inner spindle 11 can be moved in and out of one another. This creates a telescopic structure Spindle 7 reached.
  • the motor 6 is in operative connection with the intermediate spindle 10.
  • the spindle 7 is designed as a ball screw drive.
  • Figure 2 shows the adjustment unit 1 from Figure 1 in the extended state.
  • FIG. 3 shows 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.
  • the spindle is designed as a trapezoidal thread spindle 12.
  • the intermediate spindle 10 which is fixed radially via a positive fit and is axially displaceable relative to the outer spindle 9, is driven by the motor 6. This allows a rotational movement to be transmitted.
  • the outer spindle 9 moves axially via the outer trapezoidal thread connection to the housing 8 and is connected to the inner spindle 11 by means of an inner trapezoidal thread connection, which can also carry out a corresponding axial movement. This results in an axial distance of: pitch of external trapezoidal thread plus pitch of internal trapezoidal thread per revolution.
  • the intermediate spindle 10 is axially fixed to the outer casing tube 3 via the housing and is connected to it in a rotary manner.
