  • the present invention relates to a device for actuating a power control device of an internal combustion engine according to the preamble of patent claim 1 and to a method according to the features of patent claim 7.
  • the technical background of the present invention includes the US 5,983,858 A1 ,
  • the DE 10335700 A1 describes a device for actuating a throttle valve of an internal combustion engine, especially in a motorcycle.
  • a throttle grip for driver-side input of a power request a pulley is connected, another pulley is connected to a throttle valve shaft, so that depending on the driver's input desired performance, the throttle is pivotable by means of a cable.
  • Actuator available which allows engagement with the position of the throttle in the closing direction. However, preference is given to a reduced power requirement entered by the driver, before a higher power requirement specified by means of the control device, is not provided.
  • the object of the invention is therefore to increase safety at an aforementioned device for actuating a power control device of an internal combustion engine and in particular to prevent an unintentionally high engine output due to a driver not wanted control of the power control element.
  • the invention is based on the idea that the adjusting device is connected to the power control device by means of a third spring.
  • the adjusting device with the power control device is not rigid, but elastically connected, so that in particular when exceeding a predetermined force, an adjustment of the power control device is made possible without an adjustment of the adjusting device.
  • the spring force of the third spring is greater than that of the second spring. It is thereby achieved that in a regular actuation of the power control device by means of the adjusting device, the power control device is opened at least approximately without adjustment of the third spring.
  • the added spring forces of the first and second spring are preferably greater than the spring force of the third spring in the open position of the power control device ,

  • the input of the mechanical input to the driver input side of the reduced power requirement of the position of the actuating device is preferred, thus increasing safety.
  • the added spring forces of the first and second spring against the third spring are expediently effective for a mechanical connection between the input device and the power control device.
  • the power control device is connected to a shaft having a first rotation element and the first rotation element has a counter contour corresponding to a contour assigned to the input device.
  • the first rotation element is provided with a cutout, which covers an angular range of 60 ° -110 °, in particular of about 80 ° -90 °, and with a pin-shaped extension of the input device associated second rotary element corresponds.
  • the invention is further based on the idea that in a method for actuating a device according to the invention, a first sensor device for detecting the position of the input device and generating a corresponding output signal, a second sensor device for detecting the position of the power control device and generating a corresponding output signal and a Control device for controlling the adjusting device, taking into account the output signals of the sensor devices comprises, the adjusting device is deactivated if the driver input by means of the input device input power desired deviates from the adjusted by means of the actuator position of the power control device by at least a predetermined amount in the closing direction.
  • a preferred consideration of the driver's input by means of the input device desired performance is supported by the actuator does not act against the force of the first and second spring.
  • actuation of the power control device by means of the input device driver's input desired performance is deviating with a limited gradient, if the driver input by means of the input device input power desired from the set by the actuator position of the power control device by at least a predetermined amount in the opening direction differs. In this way, the safety is further increased by preventing too rapid opening of the power control device.
  • FIG. 1 1 shows a device 100 for actuating a power control device 134 of an internal combustion engine with a third spring 136 arranged between the actuating device 122 and the power control device 134.

  • the throttle valve is pivotable in the opening direction and to reduce the power in the closing direction.
  • the throttle valve is rotatably connected to a throttle valve shaft 130, which is rotatable either by means of an here designed as an electric motor actuator 122 or manually by means of a here designed as a throttle grip input device 102.
  • the driver inputs a power by means of the input device 102 by correspondingly rotating the throttle grip.
  • a first pulley 104 is rotatably connected, which operates via a cable 106, a second pulley 108.
  • the second pulley 108 is rotatably connected to a shaft 110, so that upon actuation of the throttle grip the shaft 110 is rotated.
  • the rotation or the rotational position of the shaft 110 can be detected by means of a sensor 112, which is connected in a signal-conducting manner to a control device 118 by a line 114.
  • the rotation or the rotational position of the throttle valve shaft 130 can be detected, which is connected to the control device 118 in a signal-conducting manner with a line 126.
  • the control device 118 Based on the signals from the sensors 112, 128 and possibly further signals and / or stored information, the control device 118 outputs a control signal corresponding to the power request of the driver to the control device 122 via a line 120.
  • the actuating device 122 acts on a shaft 138, which is in rotational drive connection with the interposition of a spring 136 with the throttle valve shaft 130. Both the shaft 110 and the throttle shaft 130 are acted upon by springs 116, 132 which are supported on the housing side in the throttle valve closing direction.
  • FIG. 2 A detailed view of an effective in the closing direction of the power control device 134 mechanical connection 139 between Input device 102 and power control device 134 is in FIG. 2 shown. Additionally or alternatively, in addition to an actuation by means of the adjusting device 122, a manual actuation of the power control device 134 by means of the input device 102 is possible.
  • the present arrangement represents a safety device, which in a deviation of the input by means of the input device 102 (throttle grip) driver input side reduced power desired from the setting means of the actuator 122 (electric motor) position of the power control device 134 (throttle) by at least a predetermined amount or a driver side Entering a reduced power desired by means of the input device 102 with a gradient exceeding a predetermined gradient, a preferred consideration of the means of the input device 102 (throttle grip) driver input side reduced power desired guaranteed.
  • the second pulley 108, 242 is arranged in the axial direction adjacent to the shaft 130, wherein the axes are at least approximately aligned.
  • the second pulley 108, 242 has a pin-shaped extension 246, which engages in a cutout 248 of the shaft 130 associated part 244 of the mechanical connection 139.
