And sealing rings are arranged on the inner sides of the two linear bearings.

One end of the actuating rod is connected with the hydraulic main cylinder.

Two motors are arranged on the shell in parallel, and each motor drives one actuating rod through one set of driving tooth, driven tooth and actuating rod driving tooth.

Two actuating rods are arranged in parallel

The invention has the beneficial effects that: the utility model provides a general automatic control clutch actuating mechanism and select actuating mechanism that shifts for various different motorcycle types that hope to match AMT such as commercial car, passenger car and little car with the effect that few number of teeth gear drive ratio is big, it has simple structure, low cost, uses reliable and the apparent characteristics such as compact simple to operate of volume. Therefore, a better choice is provided for reducing the development cost of the AMT and shortening the development period of the AMT, and in addition, the invention can also be used for various other mechanisms needing linear driving.

The hydraulic clutch control mechanism has the remarkable characteristics of simple structure, low cost, reliable use, compact volume, convenient installation and the like, has strong applicability, and can be used for all vehicle types using the hydraulic clutch control mechanism no matter commercial vehicles, mini-vehicles or passenger vehicles; the invention can be used for all vehicle types using the stay cable type gear selecting and shifting control mechanism. The development cost can be reduced and the development period can be shortened.
