Definitions
- the invention relates to a rotary actuator for controlling several operating functions of a technical system, with a rotary knob which can be rotated about an axis of rotation into one of several operating positions corresponding to the operating functions and the respective positioning position can be detected by a first sensor unit, with a corresponding positioning position signal from a control unit for controlling the technical system and the controlled operating function can be carried out, with a second sensor unit, from which a switch-off signal of the technical system can be detected and supplied to the control unit, through which the technical system can be adjusted into a basic function of the operating positions, with one or more arranged centrally on the rotary knob, at an angle less than 360 ° radially around the current, limited by stops slotted tracks, in the stationary stop elements to limit the angle of rotation of the rotary knob in a direction are available, the respective operating function being indicated by a display unit.
- Such a known rotary actuator is used for manual actuation of the switching functions forming the operating functions "P" for parking, “R” for reverse gear, “N” for neutral and “D” for driving an automatic transmission of motor vehicles.
- the switching signal is triggered by actuating the brake of the motor vehicle or by a door contact when leaving the motor vehicle or by an ignition switch when the ignition of the motor vehicle is switched off.
- the automatic transmission is shifted from one of the inserted gear steps "R", or “D” is switched to the gear step "Park", but the display shows the gear lever previously engaged.
- the control electronics now also switch the display to switching position "P", whereby the plunger, which can be brought into contact with the slide tracks and which can come into contact with the stops, prevents the locking disk and the rotary knob from rotating. If the motor vehicle continues to drive, the desired gear stage can then be turned by normally turning the the unlocked rotary knob can be set again, the display then also showing the correct switching level.
- electromagnets The actuation of the plunger by electromagnets requires a number of electromagnets corresponding to the number of switching stages, which is very complex.
- two electromagnets are usually energized during operation, which causes high power consumption and considerable self-heating.
- the object of the invention is therefore to provide a rotary actuator of the type mentioned which, with a simple construction, requires reduced power consumption and causes only a small amount of self-heating.
- This object is achieved in that the stop elements against a spring force of cams of a cam plate can be moved from an out of reach position into the slide tracks, the cam plate being rotatably driven by an electric motor and the respective rotational position of the cam plate being detectable by a third sensor unit, one of which Corresponding rotational position signal of the control unit can be fed.
- the rotary knob on a radially circumferential path can have a plurality of axially directed locking recesses corresponding to the set positions, which are evenly distributed over 360 ° around the circumference, in each of which one or more axially displaceable bar guided and acted upon by a spring force in the locking direction locking elements which can be locked by turning the rotary knob into the adjacent Rastver recesses.
- the stop elements and / or the locking elements can be movable radially to the axis of rotation. However, it leads to a compact design if the elements and / or the locking elements are movable axially to the axis of rotation.
- tappets By means of the cams, tappets can be moved from the disengaged position from the scenes into the scenery paths.
- the plungers can be spring-loaded in contact with the cam disc by prestressing the spring arms.
- Figure 1 is a side view of a turntable
- Figure 2 shows the turntable of Figure 1 in a perspective view
- FIG. 3 shows a perspective view of an axis with gear of the rotary actuator according to FIG. 1
- Figure 4 is a perspective view of a locking disk of the turntable according to
- FIG. 5 shows a perspective view of an assembly consisting of plungers, spring arms and retaining ring of the turntable according to FIG. 1
- FIG. 6 shows a perspective view of a structural unit consisting of a cam disk and a gear stage of the rotary actuator according to FIG. 1
- Figure 7 is a perspective view of a knob and a display of the
- the rotary actuator shown in the figures for controlling a plurality of operating functions of a technical system has a rotary knob 1 which can be rotated about an axis of rotation 2 into one of a plurality of adjusting positions corresponding to the operating functions.
- the rotary control shown serves for manual actuation of the shift stages "P" for parking, “R” for reverse gear, “N” for neutral and “D” for drive of an automatic transmission of motor vehicles.
- a locking disk 3 On the underside of the rotary knob 1, a locking disk 3 is concentrically arranged, which has two radially circumferential link tracks 4 and 4 'on the same diameter.
- the two slide tracks 4 and 4 ' are separated at their ends by protruding stop cams 5, 5', which form 4 stops 6 and 6 '' for the slide track and 4 'stops 6' and 6 '' for the slide track.
- a cam disk 7 is arranged at an axial distance, which is rotatably driven by an electric motor 9 via a gear stage 8.
- the cam disk 7 has a plurality of cams 10 protruding toward the locking disk 3 on a slide track 4, 4 'axially opposite lying radially circumferential track.
- plungers 11 forming stop elements can be moved axially out of a disengaged position from the slide tracks 4, 4 'into the slide tracks 4, 4'.
- the eight plungers 1 1 are evenly distributed on the circumference via spring arms 12 with egg nem radially inner retaining ring 13 which is seteil fixed to a housing, not shown.
- the locking disc 3 radially within the guide tracks 4, 4 'has a con centric radial circumferential track 14 with a number of axially directed locking recesses 15 corresponding to the setting positions, which over 360 ° evenly around are distributed.
- the track 14 axially opposite are axially guided on a housing part, not shown, in guide bores 16, which form latching elements and are acted upon by helical compression springs 17 in the latching direction against the track 14, so that the pins 16 snap into the latching depressions 15.
- the rotary knob 1 Upon rotation of the rotary knob 1 snap under compression of the helical compression springs 17, the bolts 16 from the locking recesses 15 and engage in the adjacent locking recesses.
- a further gearwheel 18 is rotatably driven by the gear stage 8 and is arranged on an axis 19 which is fixed to the gearwheel 18.
- a diametrical permanent magnet 20 is arranged on one end of the axis 19, in the magnetic field of which a rotational position sensor element 21 is arranged on a fixed circuit board 21.
- a Hall sensor 22 is arranged on the printed circuit board 1 and a permanent magnet 23 is arranged on the locking disk 3. Corresponding to the position of the permanent magnet 23 relative to the Hall sensor 22, a second rotational position signal is generated by the latter and sent to the control electronics.
- a display 24 for the gear stages with the display elements “P” for parking, “R” for reverse gear, “N” for neutral and “D” for drive of an automatic transmission is arranged.
- the display element is activated by the control electronics, the switching stage of which is currently set.
- control electronics receives a brake signal from a brake, not shown, of the motor vehicle when the brake is actuated and, for example, from a door contact when leaving the motor vehicle or from an ignition switch when switching off the ignition of the motor vehicle, a switch-off signal.
