ABSTRACT:
A new and unique automatic transmission mechanism to be preferably mounted on an automobile or the like is disclosed which contains two gear assemblies as essential components. The first gear assembly generally comprising four gear elements of a low gear, a second gear, a third gear and a top gear is arranged freely rotatable on an engine output shaft with a clutch holder axially displaceably disposed therebetween, whereas the second gear assembly comprising a single solid multi-stage driven gear is fixedly arranged on a driven shaft. The first gear assembly meshes with the second gear assembly in such a manner that a certain gear element of the former meshes with a corresponding gear section of the latter. Generally the clutch holder has four recesses at an equal angular distance in which spindle-shaped clutch members having a frictional surface are radially displaceably received so as to ensure tight frictional engagement between the clutch holder on the screw-threaded engine output shaft and one of the four gear elements. A coil spring is contained in the hollow space defined by the bores of the gear elements. Prior to the starting operation the clutch holder is located in the bore of the top gear by the resilient force of the coil spring.
