Abstract
A vehicle shifting mechanism configured for actuation of a clutch and gear-shifting of a shift drum in a transmission is disclosed, which includes a camshaft linked to the shift drum; an actuating motor for driving the camshaft to allow the camshaft to make one revolution to shift the shift drum with one gear; and a cam connected to the camshaft to coaxially rotate with the camshaft and abutting against a release bearing actuating element to actuate engagement and disengagement of the clutch. The cam has a symmetrical contour such that the camshaft driven by the actuating motor is capable of making one unidirectional revolution to enable actuation of the clutch and the gear-shifting of the shift drum to occur concurrently.

A vehicle shifting mechanism configured for actuation of a clutch and gear-shifting of a shift drum in a transmission, the clutch comprising a clutch actuating element for clutch-actuating the clutch, the vehicle shifting mechanism comprising:
- a camshaft linked to the shift drum;
- an actuating motor linked to and driving the camshaft, for allowing the camshaft to make one revolution to shift the shift drum with one gear;
- and
- a cam connected to the camshaft to coaxially rotate with the camshaft and abutting against the clutch actuating element of the clutch to actuate engagement and disengagement of the clutch, wherein the cam has a symmetrical contour such that the camshaft driven by the actuating motor is capable of making one unidirectional revolution in order to enable actuation of the clutch and the gear-shifting of the shift drum to occur concurrently.
