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

Abstract

The invention relates to the technical field of clutches, and discloses an electrohydraulic servo clutch, an electronically controlled separation or combination operation mode of a pressure plate type gearbox including the electrohydraulic servo clutch, and a vehicle equipped with the electrohydraulic servo clutch. The electro-hydraulic servo clutch of the present invention includes a booster cylinder, four control pistons, an oil pot, a booster piston solenoid valve and a sensor. The working force of the working chamber is equal to that of the booster cylinder. The push rod stroke is displayed by a self-adjusting stroke sensor, the booster piston adopts a spring return, the oil pot adopts a cartridge design, and the seal of the hydraulic master cylinder adopts a two-way Y-ring design. It can be directly installed on the existing gearbox bracket without changing the existing installation method. It can also realize that the hydraulic chamber does not need to exhaust air, and monitor the hydraulic leakage in real time through the program. It is especially suitable for gearboxes with diaphragm pressure plate type of electronically controlled separation and combined operation.

Description

technical field [0001] The present invention relates to the technical field of clutches, in particular to an electrohydraulic servo clutch suitable for a gearbox with electronically controlled separation and coupling actions, suitable for vehicles such as AMT or other automatic control clutches, especially suitable for electronic control separation and coupling Operation mode Diaphragm pressure plate type gearbox. The invention also relates to a gearbox of the diaphragm pressure plate type in an electrically controlled separation and combination operation mode equipped with such a clutch and a vehicle equipped with such a clutch. Background technique [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. ...
