Definitions

  • Load adjusting device with a throttle valve determining the performance of an internal combustion engine, which is connected in a rotationally fixed manner to a throttle valve shaft mounted in the throttle valve housing, the throttle valve shaft having an accelerator pedal-side mechanical linkage side and an actuating linkage side, which is assigned a coupling element for mechanically decoupling the throttle valve and an actuator motor a device for reporting the respective position of the throttle valve shaft to an electronic control device.
  • the throttle valve is usually actuated on the accelerator pedal side via a driver connected to the articulation side of the throttle valve shaft, which is connected to the vehicle pedal for this purpose by means of a Bowden cable.
  • the throttle valve shaft is controlled by an electric servomotor assigned to the load adjustment device. This is preceded by manual control by the driver. It is therefore necessary to mechanically decouple the throttle valve from the electric servomotor for defined angular ranges. Because of this decoupling, it is necessary for the control quality of the load adjustment device to report the local position of the electric servomotor. The position is recorded by the feedback device, which is assigned to a control device is.
  • the actual part of the device for the feedback on the accelerator pedal side mechanical articulation side of the load adjusting device is assigned to the position of the servomotor.
  • the invention is based on the object of designing a load adjustment device in such a way that all parts essential for the feedback device can be accommodated in a space-saving and well-protected manner.
  • the object is achieved according to the invention in that the device for feedback has a first transmission element, which is arranged on the throttle valve shaft in a rotationally fixed manner and which interacts with a first potentiometer, and in addition a second transmission element which is freely rotatably mounted on the throttle valve shaft and which interacts with a second potentiometer.
  • This has housed a very inexpensive and space-saving arrangement of all essential parts of the device for feedback on the throttle valve shaft. This is achieved in particular in that the two potentiometers and the associated transmission elements are arranged next to one another.
  • the transmission element which is arranged on the throttle valve shaft in a rotationally fixed manner, is designed as a throttle valve lever which is in contact with the first potentiometer via a wiper driver, all parts being accommodated in a housing.
  • the placement of the potentiometers, slider drivers and transmission elements in a single housing ensures good protection against damage and dirt.
  • the second transmission member which is freely rotatably mounted on the throttle valve shaft, is designed as a driver element with at least one stop, against which the throttle valve lever can be brought into contact and which is in contact with the second potentiometer via a second wiper driver, which is arranged in the same plane as that first potentiometer.
  • the second driver element has a free-wheeling segment with a stop in which the throttle valve lever is adjustable and that the driver element on the actuating articulation articulation side is drive-connected via a gear element to an electric motor that can be controlled by a control device.
  • the stop provided in the driver element ensures that the throttle valve lever is adjusted in the idle control range.
  • the corresponding setpoint information is passed on to the control device via the second potentiometer via the actual value detection device, and the electric motor for adjusting the throttle valve is thereby controlled until the throttle valve is set to the desired setpoint, which is then compared with the actual value determined by the first potentiometer. If the accelerator pedal lever and thereby the throttle valve lever are adjusted, the driver element remains in its position since the throttle valve lever can move freely due to the advantageous arrangement.
  • An advantageous embodiment of the invention is that the driver element on the actuator Articulation side is drive-connected via a gear element to an electric motor which can be controlled via a control device. This provides a drive connection between the throttle valve shaft and the electric motor in a simple manner.
  • the vehicle pedal is connected to the throttle valve lever directly or indirectly via a setpoint lever that can be freely pivoted on the throttle valve shaft in a defined area, and that a freewheel hook is arranged on the throttle valve shaft in a rotationally fixed manner, which is in a setpoint lever provided freewheel segment engages, is brought into contact with a stop spring against a stop delimiting the freewheel segment and is connected in terms of drive to the throttle valve lever via the throttle valve shaft.
  • the return spring acts on the throttle valve shaft by means of the lever arm and pulls it in the closing direction for safety reasons.
  • the setpoint lever can be used as a throttle valve drive lever and for idle control operation.
  • a very space-saving arrangement is also obtained by arranging the two potentiometers in one plane.
  • the parts shown in the frame 18 according to FIG. 1 form an actuator or a load adjustment device 10, the parts being combined in one structural unit.
  • the load adjusting device 10 includes a servomotor or electric motor 14, which is connected to a throttle valve 9 via a gear mechanism 4, which is only indicated schematically. The actuating forces of the electric motor 14 are transmitted to the throttle valve 9 via the transmission 4, and an adjustment to the desired position is thereby brought about.
  • the load adjustment device 10 can be adjusted via an accelerator pedal 1, wherein a lever 3 is adjusted by actuating the accelerator pedal 1 and is prestressed in the idling direction LL via a return spring 2.
  • the accelerator pedal 1 is connected to a driver 6 by means of a throttle cable 5, so that when the accelerator pedal 1 is actuated, the driver 6 is displaced in the direction of the full load stop VL.
  • Return springs 7 are connected to the driver 6 and bias them in the idling direction LL. As long as the throttle cable 5 is not acted upon, the driver 6 rests against the idling stop LL assigned to it. Due to the fixed arrangement of the spring 12, a direct return of the throttle valve 9 is achieved.
  • the function of the spring is described in more detail below and illustrated in Figure 2.
  • the load adjustment device has a second control element part 16 which can be connected to an electric motor 14.
  • the control element part 16 is also only indicated schematically in FIG. 1 and can correspond to a gear not shown in the drawing.
  • the two control element parts 8 and 16 are not firmly connected to one another, but can only be coupled in one direction of movement, namely in the upward direction.
  • the electronic control device 17 which contains processing, logic and control circuits, is indicated schematically.
  • the control device 17 stores values for adapting the vehicle and processes the digital or digitized values of various input variables, which then regulate the desired position of the throttle valve 9 via an analog part.
  • the electronic control device 17 cooperates with an actual value detection device 19 belonging to the control element part 8 and an actual value detection device 20 assigned to the second control element part 16 and determining the respective position of this control element part 16.
  • the first actual value detection device 19 according to FIG. 1 corresponds to a first potentiometer 23 and the second actual value detection device 20 corresponds to the potentiometer 24 shown in FIGS. 2 and 3.
  • the control device 17 has the task of all input signals, e.g. the engine speed by means of the potentiometers 23, 24 (FIG. 2) and to compare them. If, for example, the actual speed deviates from the setpoint speed, the actuator is activated until the specified speed has been reached.
  • the electronic control device 17 also detects signals via an idle contact 29, which is activated by the driver 6, when the latter comes to rest against the idle stop LL assigned to it.
  • the electronic control device 17 serves the purpose of building up a safety logic relating to the control of the first and second control element parts 8, 16. As soon as the electronic control device 17 or the electric motor 14 no longer function properly, the throttle valve 9 is moved in the direction of the maximum Idle position preloaded spring 43 in the idle emergency position LL not moved.
  • the actuator 10 shown only schematically in the frame 18 in Figure 1 is shown in detail. It consists of a throttle valve housing 30, in which a throttle valve shaft 32 with a throttle valve 9 is arranged.
  • a setpoint lever 39 is freely rotatably supported in a defined area by means of a roller bearing 51 on the end of the throttle valve shaft 32.
  • the setpoint lever 39 has a freewheel segment 41 (FIG. 4) which serves to receive a freewheel hook 40 which is fixedly arranged on a lever arm 44.
  • the actuating forces emanating from the accelerator pedal 1 are transmitted to the throttle valve shaft 32 via the setpoint lever 39 and the freewheel hook 40.
  • the freewheel hook 40 can move freely in the freewheel segment 41.
  • the setpoint lever 39 is also connected via the freewheel hook 40 on the actuating articulation side of the throttle valve shaft 32 to a throttle valve lever 21, which is connected to the throttle valve shaft 32 in a rotationally fixed manner.
  • a first grinder driver 22 On the surface of the throttle valve lever 21 facing the throttle valve 9 there is a first grinder driver 22 which is in contact with a first potentiometer 23.
  • the potentiometer 23 and the grinder driver 22 are shown schematically in FIG. 1 by the actual value detection device 19, which forwards the actual value position of the throttle valve shaft 32 to the control device 17 as a signal.
  • a freewheel bell 45 designed as a driving element 25, which is freely rotatably mounted on the throttle valve shaft 32 by means of a slide bearing 54 and has a web 56 at its upper end which overlaps the upper end of the throttle valve lever 21.
  • a second wiper 37 is arranged on the web 56 and is in contact with a second potentiometer 24.
  • the second potentiometer 24 and the grinder 37 are shown schematically in FIG. 1 by the actual value detection device 20, which forwards a corresponding signal for the idle control range to the control device 17.
  • the driver or the freewheel bell 45 is equipped with a cylindrical extension for receiving a drive wheel 59, which can be drive-connected to the electric motor 14 via a transmission 4 shown schematically in FIG.
  • the driver element 25 has a stop 46 against which the throttle valve lever 21 is pulled by means of the return spring 42, so that the electric motor 14 can adjust the throttle valve 9 for the idle control range via the driver element 25 and the throttle valve lever 21. If the vehicle pedal 1 is actuated, the electric motor 14 is deactivated, so that the driver element 25 of the throttle valve lever 21 can move freely in the freewheeling segment 27. The throttle valve 9 is now adjusted by means of the setpoint lever 39.
  • the two potentiometers 23, 24, the driver element 25, the throttle valve lever 32 and the grinder drivers 22, 37 are located in a closed housing 36, so that these parts are protected from dirt and damage. It is also advantageous if the two potentiometers 23, 24 are arranged in one plane on two different circular paths, and that the driver element 25 and the throttle valve lever 21 are arranged close to one another, so that all parts of the actuator 10 can be accommodated in the smallest space.
