Definitions

  • the invention relates to an over-rotation protection arrangement for a rotatable control element in a motor vehicle, the rotation range is more than a complete revolution, and having a rotor with a molded multi-start spiral track, wherein the spiral track has at least one ramp.
  • Rotatable controls can either be performed unlimited rotation or they have a predetermined range of rotation, which usually provides a mechanical rotation limitation. If the range of rotation is less than one revolution, the range of rotation can be easily limited by mechanical end stops. Turning stops are more difficult to provide when the operating element has a range of rotation that is more than a complete revolution. If no rotation restrictions are provided in such a turntable, then at least precautions must be taken so that an actuation of the operating element beyond the intended rotation range leads to no damage.
  • the steering angle sensor for a motor vehicle is described, which is actuated via the steering wheel and the steering shaft.
  • the steering angle sensor has a rotor with an integrally formed multi-start spiral contour, in which a functional element for determining the number of revolutions of the rotor is guided.
  • the spiral contour has ramp-like projections at its beginning and / or end region which, when an end region is reached, reflects the functional element back onto an adjacent path of the spiral contour.
  • the ramp-like projections act as an overspeed protection and protect the functional element and the spiral contour from damage.
  • the steering angle sensor has no real rotation limitation.
  • This object is achieved in that a release lever is guided in the spiral track, which shifts a sliding block in the plane of a locking segment connected to the rotor when running on the ramp.
  • the spiral track of the rotor is used here for actuating a release lever.
  • This axial disengagement movement is used to push the actual stop element, a so-called sliding block in a locking track, which presses the sliding block via a locking segment, which is connected to the steering column, in a rotationally fixed Gleitsteingephaseuse.
  • Release mechanism, sliding block and Gleitstein housing can be made of metal, but due to the design also made of plastic and attach anywhere, especially in the steering line, z.
  • a steering column module a power steering unit, a steering column or a coil spring cassette.
  • the storage of the sliding block is preferably carried out here as a linear bearing with a guide pin, but may alternatively be realized by a pivotal mounting of the sliding block.
  • the geometries and materials of the spiral track and disengaging mechanism can be optimized for the lowest friction values and noise, while the load-bearing components can be optimized in terms of their shape for strength.
  • the rotor may have a ramp at the beginning and at the end of the spiral track, so that the over-rotation protection arrangement can be effective for both directions of rotation.
  • this may advantageously have a guide pin which is slidably mounted in a Gleitsteingeophuse.
  • the sliding block is slidably mounted on a guide pin which is connected to the Gleitsteingephaseuse.
  • the sliding block is loaded with a spring which returns the pressed by the release lever in the blocking position sliding block to its original position. It is also advantageous if a spring is provided which centers the sliding block within the sliding block housing. It is particularly advantageous if a single spring is provided which fulfills both functions at the same time.
  • an engagement cam is formed on the locking segment, which pushes the sliding block out of the locking track when it encounters the sliding block. This can be effectively prevented that the sliding block outside the end positions of the control element, the movement of the steering shaft.
  • the control element may be a steering wheel with a steering angle sensor or an electric turntable, or in particular also, in combination of both features, a steer-by-wire steering wheel.
  • a steering wheel has a steering angle sensor which has a rotor with a multi-start spiral track, and in which the spiral track of the steering angle sensor simultaneously guides the release lever of the overspeed protection arrangement.

  • FIG. 1 shows in a side view parts of a steering angle sensor 1 with an overspeed protection arrangement. It was dispensed with the representation of housing parts that can accommodate the arrangement, as well as the presentation of electronic components for detecting the angle of their concrete embodiments as, for example, from DE 198 35 972 C1, known and can be assumed for explaining the Matterfitschan extract invention insignificant are.
  • the steering angle sensor 1 has a rotor 2, which can be mounted on the steering column, not shown, of a motor vehicle and is driven there by a torque-locking connected to the steering wheel steering spindle.
  • the range of rotation of a steering wheel is usually +/- 2 to 2.5 revolutions, based on the center position defined by the straight-ahead position of the wheels.
  • the steering angle sensor is mounted in a so-called steer-by-wire vehicle in which, during steering, the adjustment of the wheels takes place via an actuator which is controlled by signals of the steering angle sensor. Since there is no direct mechanical connection from the steering wheel to the wheels in such a vehicle, there is the problem that reaching the limit positions of the wheels for the driver is not is immediately recognizable, since he receives, for example by reaching end stops, no feedback on the wheel position.
  • the arranged in most vehicles in the steering wheel housing airbag is often electrically connected via a ribbon cable, which is guided in a so-called coil spring cassette.
  • the ribbon cable wraps up and down in steering wheel actuations within the coil spring cassette and therefore may be damaged if the steering wheel is over-tightened. It is therefore essential for a steer-by-wire vehicle to mechanically limit the range of rotation of the steering wheel.
  • a relatively large-volume barrier segment 8 is formed on a central cylindrical portion of the rotor 2 parallel to the spiral track 3, which has the shape of a circular ring sector.
  • the side edges of this locking segment 8 form stop surfaces 7 for limiting the steering wheel rotation range.
  • a counter stop is also a relatively large volume body, hereinafter referred to as sliding block 6, provided which is mounted vertically displaceable in a sliding block housing 10.
  • sliding block 6 can be brought into the plane of the blocking segment 8 or be removed from this plane.
  • the vertical position of the sliding block 6 can be controlled such that it is located only at the beginning and at the end of the rotational range of the steering wheel extending over several revolutions in the plane of the blocking segment 8.
  • the vertical position of the sliding block 6 is controlled by a release lever 5, which is pivotally mounted with a first end portion on a boom 15 of the Gleitsteingephinuses 10, and at the second end portion of a pin 14 (recognizable in Figures 2c and 3c) is formed, the is guided in the spiral track 3 of the rotor 2.
  • a release lever 5 which is pivotally mounted with a first end portion on a boom 15 of the Gleitsteingephinuses 10, and at the second end portion of a pin 14 (recognizable in Figures 2c and 3c) is formed, the is guided in the spiral track 3 of the rotor 2.
  • End portion of the release lever 5 is the bottom of the sliding block 6, so that the sliding block 6 can be raised by vertical movements of the release lever 5 or lowered.
  • FIG. 2 shows, in a plan view 2 a and two sectional views (2 b, 2 c), the over-rotation protection arrangement in a central rotation region of the steering wheel. From the figure 2c it can be seen that the pin 14 rests on a flat portion of the spiral track 3. As a result, the resting on the release lever 5 sliding block 6 is in a position below the plane of the locking segment 8, so that the rotor 2, and thus at the same time the steering wheel connected to the rotor 2 is freely rotatable.
  • FIG. 3 shows the overspeed protection arrangement in one of its two end positions, in which the further actuation of the steering wheel is blocked in one direction of rotation.
  • the spiral track 3 forms at its beginning and at its end in each case a ramp 4, one of which can be seen in FIG. 3c.
  • the sliding block 6 is rotated within the Gleitsteingephaseuses 10 around the guide pin 9 until the adjacent abutment surface 7 opposite outer surface of the sliding block 6 on the inner wall 1 1 of Sliding block housing 10 hits and blocks there. Thus, the rotational movement of the steering wheel is stopped in this direction.
  • the over-rotation protection arrangement is characterized in that they form virtual end stops for the steering wheel operation.
  • the relatively high forces to block the steering wheel movement are here by robust trained elements, namely by the blocking segment 8, which received the sliding block 6 and the Gleitsteingephaseuse 10.
  • the spiral track 3 and the release lever 5 are loaded only with the small forces, which requires the vertical displacement of the sliding block 6.
