Shifting execution mechanism for dual clutch transmission

A shifting execution mechanism for a dual clutch transmission, comprising:

• a front shell, a rear shell, at least two hydraulic cylinders, and at least one connecting sleeve;
• wherein the at least two hydraulic cylinders are mounted along the same axis, two ends of the hydraulic cylinders are clamped between the front shell and the rear shell;
• wherein each hydraulic cylinder is mounted with a shifter, a positioning seat and two sealing plates, the two sealing plates are mounted in the hydraulic cylinder and disposed respectively adjacent to two ends of the hydraulic cylinder, the positioning seat is mounted in the hydraulic cylinder and disposed between the two sealing plates;
• wherein the shifter includes a shifting fork and a connecting plate, the connecting plate extends into the hydraulic cylinder from an outside of the hydraulic cylinder, the connecting plate is located between the two sealing plates and engaged with the positioning seat to form an engagement for restricting movement;
• wherein every two adjacent hydraulic cylinders are connected together through one connecting sleeve;
• wherein a first hydraulic chamber is defined between the connecting sleeve and the sealing plate located adjacent to the connecting sleeve in each hydraulic cylinder, the connecting sleeve is defined with a first oil path in communication with the first hydraulic chamber;
• wherein a second hydraulic chamber is defined between the front shell and the sealing plate located adjacent to the front shell in the hydraulic cylinder which is connected with the front shell, the front shell is defined with a second oil path in communication with the second hydraulic chamber;
• wherein a third hydraulic chamber is defined between the rear shell and the sealing plate located adjacent to the rear shell in the hydraulic cylinder which is connected with the rear shell (30), the rear shell is defined with a third oil path in communication with the third hydraulic chamber.
