Gear shifting device with clutch and synchronizer for transmission

The utility model relates to a gear shifting device for a transmission capable of achieving gear shifting. The gear shifting device is provided with a gear shifting engagement sleeve, a friction clutch assembly and an operating element. The gear shifting engagement sleeve can move between the first position and the second position, a first idler wheel can rotate relative to a shaft in the first position, and the gear shifting engagement sleeve connects the first idler wheel with the shaft in a torsion resisting mode in the second position. The friction clutch assembly can move between the first position and the second position, and two parts of the friction clutch assembly can rotate relative to each other in the first position and are connected in the second position. The operating element can move between the neutral gear position and the first gear shifting position within one degree of freedom. In the neutral gear position, the gear shifting engagement sleeve and the friction clutch assembly can located at the first positions of themselves. In the middle portion, the gear shifting engagement sleeve is located at the second position of itself, and the friction clutch assembly is located at the first position of itself. In the first gear shifting position, the gear shifting engagement sleeve and the friction clutch assembly are located at the second positions of themselves.
