Transmission power switch device assembled with rotary shaft

摘要

A transmission power switch device assembled with rotary shaft has a simplified structure and provides power transmission and switching effect. The transmission power switch device includes a rotary shaft connected with a power source. On the rotary shaft are disposed a first drive mechanism, a second drive mechanism and a brake device rotatable with the rotary shaft. The brake device is movable on the rotary shaft to selectively brake the first drive mechanism or the second drive mechanism so as to transmit power to an output shaft.

1. A transmission power switch device assembled with rotary shaft, comprising a rotary shaft defined with an axis, on the rotary shaft being disposed a freely rotatable first drive mechanism, a free rotatable second drive mechanism and a brake device rotatable with the rotary shaft, wherein:
the first drive mechanism having a drive gear mounted on the rotary shaft and a driven gear driven by the drive gear; the second drive mechanism having a drive gear mounted on the rotary shaft and a driven gear driven by the drive gear of the second drive mechanism; and the brake device being at least movable between a first position and a second position to selectively brake the first drive mechanism or the second drive mechanism to output power; wherein the driven gear of the second drive mechanism is mounted on a differential mechanism, the differential mechanism having an output sleeve, the output sleeve and the driven gear of the second drive mechanism being keyed with each other, the driven gear of the second drive mechanism being synchronously rotatable with the output sleeve.
