3, the car load fuel consume is higher, and exhaust emissions is big.
Summary of the invention
In order to overcome above defective, the utility model provides a kind of gear selecting mechanism that increases gear selecting quantity that has, this mechanism is on the basis of original structure, the part of the gear selecting piston leverage (3) in the original structure is improved forming.
Gear selecting in the pneumatic AMT automatic gearbox gear shifting of the automobile described in the utility model actuator partly comprises: left side gear selecting cylinder (4), shift selection arm (5), actuator's seat band cover and oil seal assembly (6), pad (7), gear selecting transition axis assembly (8), air relief cock (9), seal ring (10), cylinder sleeve assembly (11), bush Assembly (12), pad (13), right side gear selecting cylinder (14), right position solenoid valve (15), location solenoid valve (16), left side position solenoid valve (17) etc.Right side gear selecting cylinder (14) and left side gear selecting cylinder (4) are installed in the left and right sides of actuator's seat band cover and oil seal assembly (6) respectively, cylinder sleeve assembly (11) is contained on the gear selecting transition axis assembly (8), bush Assembly (12) is positioned at right side gear selecting cylinder (14), gear selecting transition axis assembly (8) passes bush Assembly (12) from right-hand member and forms whole gear selecting transition axis assembly, this integral body gear selecting transition axis assembly is connected with actuator's seat band cover and oil seal assembly (6), and shift selection arm (5) is contained on actuator's seat band cover and the oil seal assembly (6); Right position solenoid valve (15) and location solenoid valve (16) are housed on right side gear selecting cylinder (14), a left side solenoid valve (17) are housed on left side gear selecting cylinder (4), all solenoid valves by screw on left and right sides gear selecting cylinder.Gear selecting mechanism after the improvement as shown in Figure 2.
As a kind of improvement of the present utility model, the diameter of right side gear selecting cylinder (14) is greater than the diameter of left side gear selecting cylinder (4).
In the work, when left side position solenoid valve (17) and right solenoid valve (15) when switching on simultaneously, pressurized air enters left side gear selecting cylinder (4) and right side gear selecting cylinder (14) respectively by these two solenoid valves, because the diameter of right side gear selecting cylinder (14) is greater than the diameter of left side gear selecting cylinder (4), so gear selecting transition axis assembly (8) and cylinder sleeve assembly (11) are to left movement, drive shift selection arm (5) motion simultaneously, when the boss in the middle of cylinder sleeve assembly (11) left side and the lining bush Assembly (12) is fitted, motion stops, the motion of gear selecting transition axis assembly (8) also stops, it is meta that shift selection arm this moment (5) mediates, and has so just realized that gear selecting mechanism increases the purpose of a gear selecting position.
After improving, the structure of the gear selecting mechanism in the pneumatic AMT automatic gearbox gear shifting of the automobile described in the utility model actuator more becomes reasonable, the state that an increase left side position solenoid valve and a right solenoid valve are switched on simultaneously makes the air inlet simultaneously of left and right side gear selecting cylinder, and air relief cock can be drained the unnecessary gas that occurs in the gear selecting process; After gear increased, the car load operating ratio was more steady, can mate with multiple mechanical gearbox.
