Definitions

  • the invention relates to a hand control lever, in particular for the operating platform of a vehicle, with at least one electrical actuator for delivering control signals to at least one work function in response to pivoting of the hand control lever and / or in response to the operation of at least one arranged on the hand control lever actuator.
  • a selector lever for motor vehicle transmission is shown in which are provided to prevent inadvertent switching in certain speed steps fuses, which are represented by a backdrop with scenes stages.
  • a locking element usually a guided in the shift lever rod locking rod, which locks in this way the selector lever or prevents that can be changed to another gear.
  • the locking rod can be over a Move actuator on the handle of the selector lever from the scenes stages and then releases the selector lever. To avoid noise after releasing the push button, the return movement of the locking element is damped.
  • a hand control element according to the preamble of claim 1 is known for example from GB 2 248 102 A.
  • a hand control element according to the preamble of claim 1 is known for example from GB 2 248 102 A.
  • the object of the invention is based is to provide a hand control lever of the type mentioned in such a way that the risk of accidental release of work functions is easily avoided and / or that the operation of the work function is disabled under certain circumstances.
  • At least one manually activatable activation element communicating with at least one electrical switching element is provided in the region of the actuating handle of the hand control lever.
  • the switching element cooperates with an electrical locking control unit or a locking logic in order to activate or deactivate the at least one actuating transducer of the hand control lever in response to actuations of the activating element for the purpose of outputting control signals.
  • the locking control unit can be designed so that control signals are forwarded by the control only to the work function, if previously the activation element is actuated deliberately. Otherwise, there is a suppression of the control signals.
  • the hand control lever is designed in the manner of a joystick, which can be pivoted about a universal joint in two directions and is urged by spring force into its middle neutral position. At least one actuating transducer is provided for influencing at least one associated work function for each pivoting direction.
  • Joystick-like control levers allow easy operation of multiple work functions.
  • a hand control lever in the manner of a joystick for the operation of a loader, in particular the loader of an agricultural or industrial work vehicle considered.
  • the loader boom of the loader can be lowered or raised, and by lateral movements of the joystick, for example, a blade or other tool of the loader can be tilted.
  • an unintentional and unexpected operation of the loader boom and the tool must be avoided because people could be in the loader, so that here the present invention can develop their benefits particularly effective.
  • the rocker element in the region of the actuating handle, which is connected to at least one actuating transducer designed as a potentiometer for generating a control signal corresponding to the rocking position of the rocker element.
  • the patentiometer can be included in the locking strategy according to the invention.
  • a potentiometer is sufficient, which is responsible for both Wippidesen and the output signal is calibrated for the rest position of the rocker element as a zero signal.
  • it can also be provided for each of the two Wippraumen depending on a potentiometer.
  • the rocker switch for example, the oil flow of a hydraulically operated work function can be adjusted proportionally to the rocking position.
  • the work function may be a hydraulic accessory connected to the vehicle (gripper, lift, rotating mechanism).
  • a particularly advantageous embodiment of the hand control lever according to the invention results from the fact that the activation element is articulated via a pivot axis movable on the hand control lever.
  • the at least one actuating transducer is only activated for the delivery of control signals to the working functions, when the activation element is deflected by hand from its rest position against a small force (eg., Spring force, gravity).
  • a small force eg., Spring force, gravity
  • the activation element is designed like a flap and articulated in the region of the shaft-side end of the actuating handle via a transverse axis to the longitudinal axis of the pivot axis of the hand control lever.
  • the hand lever is such that the activation element has a substantially L-shaped cross-section, wherein the end of the first leg is hinged to the hand control lever and the end of the second leg ends with unactuated activation element near the free end of the actuating handle and does not protrude beyond this.
  • the second leg runs in the vicinity and substantially parallel to the operating handle. To grasp the operating handle, the hand must be pushed between the operating handle and the activating element. This is only possible because of the proximity between the second leg and the operating handle, when the second leg pivots away from the operating handle, wherein the associated switching element is triggered.
  • the activation element in the vicinity of its pivot point for example, formed as a projection, actuator, which cooperates with an actuating pin of the switching element, so that upon pivoting of the activation element from its unactuated rest position, the switching element is actuated to deliver control signals to a lock control unit.
  • control unit which evaluates the signals of the at least one actuating transducer and the at least one switching element.
  • the control unit contains a lock control unit and outputs control signals to the corresponding work functions as a function of the cited signals while observing a suitable locking strategy.
  • an electrical control device which receives and evaluates the signals of at least one actuating transducer, which responds to pivoting of the hand control lever, as well as the signals of the at least one switching element associated with the locking element.
  • the control unit accepts an activation of the at least one actuation converter, that is to say a forwarding of signals the actuator to the associated work function, only if the activation element is triggered (actuated), while the manual control lever is in its neutral position. However, if the manual control lever is initially in a position other than its neutral position, the actuating converter is not activated when the activation element is actuated. The activation is thus possible only from the neutral position of the hand lever.
  • the safety-relevant advantage that a movement of the work function (eg front loader) can only be caused when the manual control lever is moved, but not when, for example, the ignition of the vehicle is switched on when the hand control lever is deflected.
  • the activated hand lever is pivoted from its neutral position, the activation is maintained even when the activation element returns to its rest position.
  • a preferred embodiment of the invention provides, however, that the control unit cancels the activation when the activation element is in its rest position (because it was released) and the hand control lever returns to its neutral position and there remains longer than a first predetermined time interval.
  • the first time interval can be, for example, up to 2 seconds, preferably about 0.5 seconds.
  • the invention provides that the control unit cancels the activation when the manual control lever returns to the neutral position when the activation element is actuated and remains here longer than a second predeterminable time interval.
  • the second time interval is preferably up to 3 minutes, preferably about 1 minute. However, if the neutral position is traversed only briefly, the activation remains.
  • hand lever 10 is a center-centered by spring force joystick-like lever, which by means of a universal joint 12, not shown in two directions, fore and aft (x) and to the left and right (y) , can pivot.
  • the manual control lever 10 consists essentially of an operating handle 14, a central console 16 and a subsequent down to the console 16 lever shaft 18, at the lower end of the universal joint 12 is located.
  • actuating transducer potentiometer
  • actuating handle 14 On the upward-facing end face of the actuating handle 14 are two manually operable actuators 20, 22, which form with associated, not shown electrical actuation converters two pressure switch. With the actuators 20, 22, the operator control signals (z 1 , z 2 ) trigger, for example, to switch between different additional functions.
  • a manually operable rocker 24 is arranged with an upper rocker arm 26 and a lower rocker arm 28.
  • the rocker 24 is associated with a not shown, designed as a potentiometer actuator actuator that outputs control signals to auxiliary devices that are proportional to the rocker position.
  • a flap-shaped activation element 34 (safety flap) is pivotably articulated to the console 16 via a pivot axis 32 extending transversely to the lever longitudinal axis 30, which by means of a spring, not shown, with low spring force in its rest position shown in FIG is urged.
  • the activation element 34 has a substantially L-shaped cross section with two legs 36, 38.
  • the free end of the first leg 36 forms with the pivot axis 32, the pivot point of the activation element 34.
  • the second leg 38 runs at an acute angle to the lever longitudinal axis 30 and terminates near the upper free end of the actuating handle 14.
  • the free rounded end of the second leg 38 does not protrude beyond the front side of the operating handle 14 and thus offers no possibility of attack for accidental deflection.
  • a downwardly extending projection 40 is formed. This acts with the actuating pin 42 of a micro switch designed as a switching element 44 which is urged by the force of a spring in the direction of projection 40. In the illustrated rest position, the projection 40 does not engage the actuating pin 42, so that the latter does not trigger a switching signal (s) of the switching element 44.
  • the operator To grasp the operating handle 14, the operator pushes his fingers between the activation element 34 and the operating handle 14 and pushes the activation element 34 from its illustrated rest position to the left (with respect to FIG. 1). At the same time, the projection 40 presses against the actuating pin 42 and triggers a switching function in the switching element 44. If the operator takes her hand away from the operating handle 14, the activating element 34 pivots back into its basic position as a result of spring force. In this case, the switching element 44 is switched back and outputs no switching signal.
  • a tilt switch 45 indicated in Fig. 2 is further arranged, which can be tilted between ON and OFF.
  • the toggle switch 45 By the toggle switch 45, the manual control lever 10 can be switched to its ready state.
  • Fig. 2 the manual control lever 10 with its actuators (potentiometer of the lever shaft 18, pressure switch 20, 22, potentiometer of the rocker element 24, switching element 44) is indicated as a block.
  • the signals of the actuation transducers are evaluated by a control unit 46, which outputs control signals to actuators 48, 50, 52 in accordance with an evaluation algorithm.
  • the actuators 48, 50, 52 control associated hydraulic valves 54, 56, 58 of work functions.
  • the valves 54, 56, 58 are, for example, electro-hydraulic control valves of a Front loader.
  • valve 54 affects the raising and lowering of a loader boom, not shown, the valve 56, the tilting of a gripper articulated at the free end of the loader boom and the valve 58, the opening and closing of the gripper.
  • the control of a hydraulic auxiliary device by the rocker 24 was not shown in Fig. 2 in detail.
  • the pressure switches 20 and 22 can serve the switching between various additional functions.
  • the evaluation of the signals takes place in the control unit 46 using an algorithm.
  • An algorithm suitable for carrying out the present invention is explained below with reference to the flowchart shown in FIG.
  • step 102 the manual control lever 10 is not yet activated, that is, the controller 46 does not convert the signals of the actuation transducers 20, 22, 24, 44 into control signals for the working functions.
  • step 104 the query is whether the hand control lever assumes its neutral position and whether the activation element 34 is in its rest position. As long as these two conditions are not met, the algorithm repeats the query of step 104 at regular intervals.
  • step 104 the algorithm proceeds to step 106, where it is queried whether the activation element 34 has been actuated in the meantime and has left its rest position. As long as this is not the case, step 106 repeats its query at regular intervals. If an activation of the activation element 34 is detected by step 106, the algorithm proceeds to step 108, through which the manual control lever 10 is activated. The hand control lever 10 is now in its working state in which, depending on its pivoting control signals are issued to associated work functions.
  • step 110 the query is whether the hand lever 10 is in its neutral position. If this is not the case, then the activation of the manual control lever 10 is maintained and the query of step 110 is repeated at regular time intervals. Here, the manual operating lever remains in its working state even when the activation element is released and returns to its rest position.
  • step 110 determines whether the handset lever 10 is in its neutral position. If it is determined in step 110 that the handset lever 10 is in its neutral position, the algorithm proceeds to step 112 where it is queried that the activation element 34 is still actuated. If the answer of step 112 is affirmative, the algorithm proceeds to step 114, where it is checked whether the activation element 34 has been continuously pressed during the last full minute. If so, in step 116 the handset lever 10 is deactivated and the algorithm is returned to step 104. This has the consequence that in a manual control lever 10 in the neutral position, this only remains activated if the activation element 34 has not been operated for more than one minute. Otherwise, the activation is canceled. This prevents the activation element 34 is blocked in an inadmissible manner without the operator takes the handset lever 10 and simultaneously actuates the activation element 34 with her hand.
  • step 114 If the answer in step 114 is negative, d. H. the activation element was not actuated continuously during the last minute while the operating lever 10 was in its neutral position, then the algorithm returns to step 110 and the manual control lever 10 remains activated.
  • Step 118 it is queried whether the activation element has not been actuated during the last half second. If so, in step 116 the handset lever 10 is deactivated and the algorithm is returned to step 104. Otherwise, the algorithm returns to step 110. This has the consequence that with unconfirmed activation element 34 of the manual control lever 10 can only be moved through its neutral position for a short time, without being automatically deactivated. If, however, it remains in its neutral position with unactivated activation element 34 for a longer time (longer than 0.5 seconds), it is deactivated. In this case, the polling loop must be run again beginning at step 104.
  • signals from other actuation transducers for example the signals of the pressure switches 20, 22 and / or the rocker switch 24, can also be included in the interlocking.
