Electric hydraulic servo clutch and corresponding gear box and vehicle

Abstract

The invention relates to the technical field of clutches and discloses an electric hydraulic servo clutch, a gear box taking an electronic control pressure disc way to perform separation and combination comprising the electric hydraulic servo clutch, and a vehicle provided with the electric hydraulic servo clutch. The electric hydraulic servo clutch comprise an assistant cylinder, four control pistons, an oil pot, an assistant piston, a magnetic valve and a sensor; the assistant piston adopts a double-guide ring design; the magnetic valve adopts the directly operated type pneumatic magnetic valve with high responding speed; the acting force of a hydraulic work cavity is equivalent to that of the assistant cylinder; the stroke of a push rod is displayed a stroke sensor with a self-adjusting structure; the assistant piston adopts a spring to reset; the oil pot adopts a container type design; and a hydraulic main cylinder is sealed by a two-way Y-shaped ring design. The electric hydraulic servo clutch can be directly installed on the existing gear box support, and no change is required for the existing installing way. In addition, in the electric hydraulic servo clutch provided by the invention, a hydraulic cavity is free from air exhausting and hydraulic leakage can be monitored in real time through a procedure, therefore, the electric hydraulic servo clutch is especially applicable to the gear box taking the electronic control diaphragm pressure disc type way to perform separation and combination.

Description

Technical field [0001] The present invention involves the field of clutch technology, especially a electrical hydraulic servo clutch suitable for the separation and binding action of the electrical control operation method. It is suitable for vehicles such as AMT or other automatic control clutch.Operation method Mizer -type transmission.The present invention also involves the electronic control separation and combined operating method of the clutch, the membrane pressure transmission type, and the vehicle equipped with this clutch. Background technique [0002] In the vehicle power system, the clutch is installed between the engine and the gearbox. For gear transmission with an electronic control operation method and combined action, the existing clutch control structure is more complicated, the installation is inconvenient, and the itinerary control is not accurate.If the application number is: 201020636998, the invention of China's practical new patent named "Electro -Hydrolog...

AI Technical Summary

Problems solved by technology

[0002] In the vehicle power system, the clutch is installed between the engine and the gearbox. For a gearbox with electronically controlled separation and combination actions, the existing clutch control structure is relatively complicated, installation is inconvenient, and the stroke position control is not accurate enough.

For example, the application number is: 201020636998, and the invention name is "Electro-hydraulic control power output clutch" Chinese utility model patent. The hydraulic pump and other devices that require continuous power are arranged at the rear of the transmission box power output clutch shaft, which increases the cost and space. , the structure is very large
