Abstract
A compact hub-embedded multi-stage transmission is provided which is implemented to achieve multi-stage shifting by using a multi-stage planetary gear set having a one stage or two or more stages and a double one-way clutch in order to impart an overrunning function during inertial travel, and at the same time, to allow rapid shifting to be made even with a small force for manipulating a shift lever by means of use of a forced shift function even in a driven travel state. Accordingly, product marketability can be maximized, and rapid shifting can be made even with a small force for manipulating a shift lever by means of use of a forced shift function even in a driven travel state, thereby considerably improving shifting accuracy.
