Electronic throttle control system for motorcycles
First Claim
1. Electronic throttle control system device for motorcycles that is mounted on a handlebar element, said system comprising, in combination:
- a twist-throttle control element that may be adjusted at the handlebar element by rotation along an actuation direction from an idle position to full-throttle position, a rotation-position sensor that is mounted outside the rotation axis of the twist-throttle control element, wherein the rotation-position sensor consists of a rotor unit and a stator unit, the rotor unit with the twist-throttle control element may be moved with respect to the stator unit, and the rotation axis of the rotor unit and the twist-throttle control element are positioned parallel to each other at a distance, and the rotor unit may be adjusted by means of an engagement element connected with the twist-throttle control element that includes a first number of teeth that engage with a second number of teeth on a toothed element, wherein the toothed element is coupled with the rotor unit, or the rotor unit is at least partially formed as a toothed element, and at least one return element is provided that acts against the actuation direction so that the engagement between the first and the second teeth is essentially without free play.

Abstract
An electronic throttle device 10 for motorcycles is mounted on a handlebar. A twist grip 16 may be rotated from an idle position to the full-throttle position. A rotation-position sensor 104 with a rotor unit and a stator unit is either mounted along the rotation axis of the twist-throttle control element 16 or outside of it. In the former case, an intermediary coupling unit 50 is provided that is fixed both to the twist-throttle control element 16 and to the rotor unit 46, 74 to rotate with them. In the latter case, an engagement element 92 is provided for coupling with a first toothed area 94 that engages with a toothed element 96 with a second toothed area 98. A Hall-effect rotation sensor or inductive rotation sensor is preferably used as a rotation-position sensor, whereby in the former case a rotor unit 46, 106 may be moved across from a stator unit 44, 108 with two stator partial elements 58a, 58b. In the latter case, an inductive coupling element 78 is mounted on the rotor unit 74, and an induction circuit 80 is mounted on the stator unit 76.
