Switching transmission mechanism

摘要

The mechanism has a commutation wheel (4.7) rotatably assembled on a periphery of a driving wheel (4.6), and an intermediate driving wheel (4.9) assembled around a change gear (4.1) and with the commutation wheel. The intermediate driving wheel is fixed at a control wheel (4.10) to be turned in a controlled manner by a controlling mechanism of the transmission system, and the driving wheel is axially placed between two cores (4.1.1, 4.3.1). An independent claim is also included for a clock movement comprising a display mechanism.
