Abstract
A mechanical transmission and a method for controlling the mechanical transmission. The mechanical transmission includes an input shaft, a first engagement sleeve, a second engagement sleeve, a clutch, an odd gear output shaft and an even gear output shaft. A power transmission route is formed, then by sequentially controlling the coupling and disengaging of the clutch, and the combining and quitting of the first engagement sleeve and the second engagement sleeve, the power of the input shaft is alternatively conveyed to the odd gear output shaft or the even gear output shaft, thus up-shift and down-shift operations are completed. In this way, the number of the clutch is reduced, which decreasing the volume of the transmission accordingly, and meanwhile reducing the dragging resistance produced by the clutches and the cost of the transmission, also improving the transmission efficiency.
