Handle control provided with an angular position sensor
First Claim
1. A handle control provided with an angular position sensor;
- the handle control comprises;
a supporting body, which is provided with a central through hole and is adapted to be fitted about a handlebar to be rigidly fixed to the handlebar;
a twist grip, which has a tubular shape, is rotationally carried by the supporting body and is centrally perforated to be fitted about the handlebar so as to rotate with respect to the handlebar; and
an angular position sensor adapted to read the angular position of the twist grip and comprising at least one rotor, which is supported by the twist grip to rotate along with the twist grip, and at least one reader, which is carried in a stationary position by the supporting body, is arranged close to the rotor, and is suitable for a contactless and remote reading of the orientation of the rotor;
the handle control is characterized in that the rotor of the angular position sensor is magnetless, is adapted to influence an electric field, and comprises at least one closed turn made of an electrically conductive material and having a number of lobes distributed about a rotation axis of the twist grip; and
the reader of the angular position sensor generates an electric field, which is reflected by the turn of the rotor and then the reader reads the electric field reflected by the turn.

17. A handle control provided with an angular position sensor;
- the handle control comprises;
a supporting body, which is provided with a through central hole and is adapted to be fitted about a handlebar to be rigidly fixed to the handlebar itself; a twist grip, which has a tubular shape, is rotationally carried by the supporting body and is centrally perforated to be fitted about the handlebar so as to rotate with respect to the handlebar itself; and an angular position sensor which is adapted to read the angular position of the twist grip and comprises at least one rotor, which is supported by the twist grip to rotate along with the twist grip itself, and at least one reader, which is carried in a fixed position by the supporting body, is arranged close to the rotor, and is adapted for a contactless and remote reading of the orientation of the rotor itself; the handle control is characterized in that; the rotor has at least one axial rib, which radially protrudes towards a rotation axis and axially extends for a certain length; and the grip internally has an axial seat which is engaged by the axial rib of the part of the rotor to make the rotor angularly integral with the grip and, at the same time, to allow an axial sliding between the grip and the rotor without varying the distance between the rotor and the reader.
