ABSTRACT:
A manually-operated automotive transmission has a cluster gear on which several forward drive input gears and the reverse drive input gear are formed integrally. The cluster gear has a central bore extending its full length. An input shaft clutched to as engine crankshaft is keyed at the end furthest from the engine to the far end of the cluster gear and has a loose fitting spline connection to the opposite end of the cluster gear. A portion of the input shaft between the clutch and the loose spline connection has relatively high torsional stiffness and strength, but the portion of the input shaft between the keyed connection and the loose spline connection has relatively low torsional stiffness and strength. The clearance between the teeth of the loose spline connection is sized so that relatively low torque is not transmitted through this connection. The clearance is taken up and engine torque transmitted through the loose spline connection when high operating torques are developed.
