Definitions

  • the invention relates to an activation system of a Device control device for a work vehicle having a Swing seat includes, which has a first and a second Pivoting seat position, with an activatable and deactivatable device control device, means for Determining the position of the swivel seat, which indicate when the swivel seat in the first, the second or one third swing seat position is located, with the third Pivoting seat position between the first and the second Pivoting seat position, and one in a first Switch position on and in a second switch position Disconnectable ignition switch.
  • an activation system of the beginning mentioned type at least one changeover switch for activation the device control device, which in a first and in a second changeover switch position is switchable, wherein the Device control device is activated when ideal Activation conditions are present.
  • ideal Activation conditions are only available if the Ignition switch is turned on and the means of detection indicate the position of the swivel seat that the swivel seat essentially in his first and not in his second or third swing seat position is located.
  • a release device which, compared to conventional systems, a higher security against manipulation by willful acts of a Operator offers.
  • the release device accomplishes this by requesting release conditions and a Intentional act by an operator to release the Device controller.
  • Ideal release requires the following release states: 1. the swivel seat, often associated with backhoes is in a backhoe operating position and not in another operating position, 2. the ignition switch is in the "on” position and 3. a device controller changeover switch will be in a release order for the Device controller switched, while 1st and 2nd ideal Release state is present.
  • This is an ideal release for the device control device only if the Operator the device controller changeover switch in the release position for the device control device switches, after the ignition of the working vehicle has been activated and remains in "on" position and the seat in the Backhoe operating position is located. If, after the Release for the device control device was made, a the state changes, the device control device automatically deactivated. The device control device is automatically reactivated only when the ideal Release states are available again.
  • Non-ideal release requires the following conditions: 1. The Swing seat is not in the backhoe operating position, 2. the ignition switch is in the "on" position and 3. the device controller changeover switch is in a release position for the device control device switched while 1st and 2nd non-ideal release state is present. Thus, the non-ideal release is actually a Bypass state in which the device controller changeover switch acts as a bypass switch. Of the Operator is by means of an optical alarm from a Display device of a monitor and / or by means of a Beeps from a speaker of the monitor signals that a non-ideal release is present. The signaling can by a single short-term alarm, a periodic Alarm or by a constant alarm.
  • the non-ideal release allows the operator several Perform functions when needed.
  • an operator his seat in a loader operating position or in a position between the backhoe operating position and pivot the loader operating position and manipulate his shovel or his work vehicle while simultaneously being backhoe working implement served. Swiveling the seat in any or any position disables the Device controller and requires a reactivation before the device control device is released again.
  • a memory for the Backhoe functions a hydraulic safety pressure and the operator enables the Backhoe work implement in a controlled manner on the Lower the ground if the engine stops or fails.
  • FIG. 1 shows a special work vehicle 10 in which the Invention can be used.
  • the special Work vehicle 10 which is shown in FIG. 1, is a Backhoe, which usually has two functions having.
  • the functions of this special work vehicle 10 are those of a backhoe and a loader.
  • the Work vehicle 10 includes a cabin 15, a pivotal seat 20, at least one device control device 160, a Backhoe area 50 and a loader area 60.
  • the work vehicle 10 also includes wheels 70 as well a propulsion system (not shown) with which it is on the ground is driven in a known manner.
  • the pivot seat 20 has at least two sitting positions, i. Swivel angle positions in which the seat 20 detectable is.
  • These seating positions have at least one Angular position, in which the pivot seat 20 the Backhoe area 50 faces and a Angular position, in which the pivot seat the loader area 60th is facing. Usually these are at an angle of 180 ° apart, as indicated in Figure 1. Of the Swing seat 20 is located in a backhoe or deep excavator Charger operating position, if this is within about 15 ° to the appropriate sitting position.
  • FIG. 2 shows a block diagram which shows a exemplary embodiment of the invention illustrates.
  • the Diagram includes: an ignition switch 100, a first one Seat switch 110 to determine whether the seat 20 in the Backhoe operating position is or not, one second seat switch 120 for determining whether the seat 20 in the loader operating position is or not, one Device controller 160, a device controller changeover switch 130 for releasing the device control device 160, which also acts as a bypass switch and a logical control unit 150.
  • the logical control unit can a conventional control computer on board the work vehicle 10, a conventional hard-wired switching mechanism or a conventional group of switches and relays that way are arranged that by means known to a person skilled in the art Methods the logic of the invention is feasible.
  • FIG. 3 shows a flowchart in which a detail is given Control circuit 200 for each invention Operating steps, as shown in Figure 2, shown is.
  • the operating steps shown in FIG. 3 can by techniques known to those skilled in the art Hardware and / or by software programming of the logical Control unit 150 can be implemented.
  • Step 210 d. H. with a turn on the ignition switch to to initiate a flow of energy that activates all other switch is needed.
  • the ends Process immediately with step 270 and the device controller 160 is not activated when the ignition switch 100 in step 210 is off. As soon as the ignition switch 100th is turned on, the switch position is in step 220 of the first seat switch 110 checked.
  • step 230 the switch position of second seat switch 120 determine. If the second Seat switch 120 is not in its first switch position then the process proceeds to step 240. If in step 240 the device controller changeover switch 130 in its first changeover switch position is switched, then the device control device 160 ideally activated.
  • step 220 If, at step 220, the first seat switch 110 is not in its first seated switch position, or, in step 230, the second seat switch 120 is in its first Seat switch position is, the process goes to step 270 over and the device controller 160 is not activated, unless the device controller changeover switch 130 is in step 260 in its first changeover switch position connected. If, under these conditions, the Device controller changeover switch 130 as Bypass switch is used and in its first Switching position is switched, then the process continued with step 250, in which the Device controller is not ideal, and goes to step 280, in which the operator, by means of a Monitor 180 and a display device 181 and / or a Beep generator 190 on non-ideal activation is informed.
  • FIG. 4 shows a memory 191 which contains the memory Operational safety of the activation system increases.
  • the Memory works as a failover mechanism for the case of catastrophic decay of the engine 170 and a pump 189 (see Figure 2) Hydraulic pressure. Such a failure could occur as a result z. B. a motor failure, a failure of a hydraulic Line, a failure of the hydraulic pump, etc. Should the provided hydraulic pressure fails, the memory is used 191 for temporary pressure maintenance and allows the Operate the device controller 160 to operate Appropriate control of the implement, which usually is a backhoe, and in a proper position too bring, for example, in a parking position.
