Definitions

  • the functions "fix cover” and “positioning of the sensor relative to the throttle shaft” can be separated. This considerably simplifies the design of the sensors used. Particularly when using non-contact systems, such as in Hall sensors, to achieve a high accuracy with respect to the detection of the angular position of the throttle valve, a very precise positioning of the sensor element is required. This exact positioning of a contactlessly operating sensor element can not be achieved during the relative movement of a cover element, in which a sensor element is integrated, when it is mounted on the transmission housing, since the tolerances and the dimensions of the adding components are too great.
  • the sensor module 9 After joining the components 7 and 8 of the throttle unit, the sensor module 9 is finally inserted into the opening 29 and aligned corresponding to the opening 18 in the bottom of the gear housing 7. This allows a simple adjustment of the sensor module 9 regardless of the position of the modular cover element 8 on the gear housing 7 make.
  • the alignment takes place only on the sensor module 9, which is to be inserted into the top of the modular cover element 8. In this case, the sensor module 9 takes over both the contacting of the actuator via the plug lugs to be inserted into the plug receptacles 24 and the connection of the sensor elements.
  • An alignment of the sensor module 9 regardless of the installation of the cover element 8 is particularly important for non-contact sensor systems to achieve a high measurement accuracy of crucial importance.
