Description
Technical field
The utility model relates to a kind of car gear shifting booster.
Background technique
In the process of moving shifted of automobile all relies on driver's operation selector manual lever to finish, and traditional selector exists speed change to become to lag behind, and the driver is firmly big, the shortcoming that labor intensity is big.So exploitation gear shift booster is a new problem, the gear shift booster is one and utilizes pressurized air to make the energy, reduces the splendid device of the operation strength of selector manual joystick.
Summary of the invention
The purpose of this utility model is to provide a kind of rapid operation at the existing shortcoming of above-mentioned selector, the car gear shifting booster that the speed change reflection is fast.
In order to achieve the above object, the utility model has mainly adopted following technological scheme to finish.The utility model mainly is made up of servo-cylinder seat and the servo-cylinder be located on the servo-cylinder seat, also is provided with the intake and exhaust connector assembly on the servo-cylinder seat, and the intake and exhaust connector assembly comprises dust-proof cover and is located at end cap in the dust-proof cover, is provided with suction port and air outlet in the end cap.End at servo-cylinder also is provided with dust-proof cover.In servo-cylinder, be provided with the power-assisted chamber, power-assisted is provided with piston in the chamber, piston is provided with seal ring, in piston, be provided with transmission shaft, the end of transmission shaft is provided with outer shaft sleeve, on transmission shaft, be provided with the push rod of two symmetries, the opposite design of direction, be respectively equipped with valve and intake valve port corresponding and exhaust valve port on the push rod with it, and corresponding with the inlet and outlet mouth on being located at piston.Also be respectively equipped with the opposite taper return spring of direction on the push rod.
The utility model compared with prior art has following obvious advantage and good effect.(1), a shelves booster is a new problem, the gear shift booster is one and utilizes pressurized air to make the energy, reduces the splendid device of the operation strength of selector manual joystick.(2), the power-assisted effect is directly proportional with the declutch shift lever steering force, and speed changer is produced servo action.(3), respond no hysteresis fast during speed change.(4), do not influence compressed air system.(5), gear is in the optimum position when driving, and avoids increasing engine loading, improves fuel economy.
The utility model is applicable to lorry, passenger vehicle and other vehicle.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
