Title: Two speed transmission system - ensures change from high to low speed as required output torque increases
Inventor: RUEGAMER HEINZ
IPC: F16H48/08
Filed: 1975-04-16
Abstract: The transmission gear input shaft carries a bevel gear surrounded by a spur gear. The spur gear meshes with a wheel on a layshaft which carries two other gear wheels. One of these layshaft gears meshes with a spur gear on the output shaft and the ratios of the gears in this train provide a reduced output speed. The spur gear on the output shaft surrounds a bevel gear which meshes with the bevel pinions of a differential gear which are also in mesh with the bevel wheel of the input shaft. When driving through the differential bevel pinions, input and output speeds are equal but with increasing torque the drive is transmitted through the layshaft.
