Between centers clutch mechanism wherein and gear-shifting clutch mechanism also can all or part ofly share, and to reduce installing space, reduce manufacture cost.
Want the occasion of demanded driving force input output coaxial line at some, also can increase an output shaft, form the layout of similar three shaft transmissions, output shaft is arranged in the side that input shaft A is relative with power source A, between output shaft and driven shaft, can gear transmission be used; Can also be connected by between centers clutch mechanism between output shaft with input shaft A, form one and directly keep off.
Requiring the occasion of multiple gear ratios speed change, system can arrange speed change gear and gear-shifting clutch mechanism more, realizes the variation of speed ratio.
Strict occasion is being required to system radial dimension, can a power source B is being arranged between power source A and speed change gear, forming hollow-core construction.
Requiring strict occasion to axial dimension, one or all of power source can be arranged on the side of input shaft, connects power source and input shaft by gear or other driving mechanisms.
The invention has the beneficial effects as follows mixed power system characteristics of compact layout, ensuring smooth transmission, power interruption when can realize the multiple drive modes of single motor and shift gears to AMT under automatic controlled conditions compensates and realizes dynamic gearshift.
The present invention can be widely used on the various power equipments such as automobile, rail vehicle, boats and ships, engineering machinery, farm machinery.
