The invention discloses a mechanical transmission with a multi-sectional dual-clutch mechanism and belongs to the technical field of mechanical transmitting and driving. The transmission comprises the multi-sectional dual-clutch mechanism, a first-stage speed changing mechanism and a second-stage speed changing mechanism, wherein the multi-sectional dual-clutch mechanism comprises four multi-sectional clutches, each multi-sectional clutch can complete one working section, and friction torque output of each working section is achieved through changes of the positive pressure of an independent oil filling-discharging control piston to a friction pair; changes of oil filling-discharging alternating match control are carried out between the working sections so that the friction torque output of the clutches can be continuously controlled; control match between the first-stage speed changing mechanism and the multi-sectional dual-clutch mechanism is completed by controlling six synchronizers inside the first-stage speed changing mechanism, and control match between the second-stage speed changing mechanism and the multi-sectional dual-clutch mechanism is completed by controlling six synchronizers inside the second-stage speed changing mechanism. Under the situation with the equivalent size structure, the number of gears of the mechanical transmission can be largely increased, and then the riding comfort of an automobile transmitting system is improved.
