SHIFTING EXECUTION MECHANISM FOR DUAL CLUTCH TRANSMISSION

摘要

Disclosed is a shifting execution mechanism for a dual clutch transmission. The shifting execution mechanism comprises a front shell (20), a rear shell (30), at least two hydraulic cylinder barrels (40) and at least one connecting sleeve (50), wherein the at least two hydraulic cylinder barrels (40) are mounted on the same straight line, two ends, i.e. the front end and the rear end of each hydraulic cylinder barrel are clamped between the front shell (20) and the rear shell (30), and each hydraulic cylinder barrel(40) is provided with a shifting fork assembly (60), a shifting fork locating seat (70) and two piston rings (90); every two adjacent hydraulic cylinder barrels (40) are connected together through one connecting sleeve (50), a first hydraulic cavity (A) is formed between the piston ring (90) at one end of each hydraulic cylinder barrel (40) which approaches the connecting sleeve (50) and the connecting sleeve (50), and the connecting sleeve (50) is provided with a first oil passage (56) which is in communication with the first hydraulic cavity (A); a second hydraulic cavity (B) is formed between the piston ring (90) at one end of each hydraulic cylinder barrel (40) connected to the front shell (20) which approaches the front shell (20) and the front shell (20), and the front shell (20) is provided with a second oil passage (23) which is in communication with the second hydraulic cavity (B); and a third hydraulic cavity (C) is formed between the piston ring (90) at one end of each hydraulic cylinder barrel (40) connected to the rear shell (30) which approaches the rear shell (30) and the rear shell (30), and the rear shell (30) is provided with a third oil passage (33) which is in communication with the third hydraulic cavity (C).
