Abstract
A releasable gear type spline clutch can couple a shaft to a wheel rotatably mounted on the shaft. The clutch comprises an annular clutch member axially mounted on the shaft. Mating external and internal first splines are provided respectively on the shaft and the dutch member, and mating external and internal second splines are provided respectively on the clutch member and the wheel. The pitch diameter of the second splines is greater than the pitch diameter of the first splines, and the pressure angle of the first splines is greater than the pressure angle of the second splines. The clutch member is axially shiftable between a disengaged position at which the second splines are out of mesh, and an engaged position at which the second splines are meshed. The first splines are meshed in both the engaged and disengaged positions.
