US 2006/0185427 A1 · SIGNAL DETECTOR OF ENGINE FOR VEHICLE

Abstract

Disclosed is a vehicle engine in which a crankcase is reduced in length in a crankshaft direction and in which the number of parts for an ignition signal detecting device is reduced, whereas rigidity and function of a one-way clutch for a starter mechanism is maintained. The one-way clutch is mounted on one end of a crankshaft, and a sensor of the ignition signal detecting device is positioned radially outside a cylindrical outer wall of a clutch outer component of the one-way clutch. The cylindrical outer wall of the clutch outer component includes a plurality of concave and convex parts as a signal output part in its circumferential direction, where each of the concave and convex parts extends in the crankshaft direction. The cylindrical outer wall includes an annular reinforced part having a thickness which is greater than that of a bottom wall forming the concave part.

Dependent claims

A signal detector of an engine for a vehicle, in which the engine has a one-way clutch, for a starter mechanism of the engine, which is mounted on one end of a crankshaft of the engine, the signal detector comprising:

a clutch outer member of the one-way clutch;
and
a sensor for detecting signals, in which the sensor is provided radially outside a cylindrical outer wall of the clutch outer member so as to be opposed to the cylindrical outer wall,
wherein the cylindrical outer wall of the clutch outer member has:
an outer surface of concavity and convexity as a signal output part which is detected by the sensor;
and
an annular reinforced part which is thicker than a bottom surface of the concavity of the signal output part.
