Abstract

The invention discloses an automatic control oil cylinder of an AMT gearbox dry clutch. The automatic control oil cylinder comprises a clutch ejector rod, a piston, an oil cylinder shell, a connecting block, a guide plate and an angle sensor. The piston comprises a first piston rod, a piston body and a second piston rod. The oil cylinder shell comprises a first cavity and a second cavity. An end of the first piston rod is clamped in the first cavity. The piston body is clamped in the second cavity. An end cover is arranged at an end of the oil cylinder shell. The second piston rod penetrates through the end cover and extends out of the end cover. A clamping groove is formed in one end of the piston rod. One end of the clutch ejector rod is clamped in the clamping groove. The guide plate is fixed to the oil cylinder shell. The middle position of the connecting block is connected with the guide plate and can horizontally move on the guide plate. One end of the connecting block is fixed to the second piston rod, and a sensor connecting plate is arranged at the other end of the connecting block. The angle sensor is connected with the guide plate. A connecting rod is arranged between the angle sensor and the sensor connecting plate.

Description

Technical field: [0001] The invention relates to the technical field of automobile dry clutch control, in particular to an automatic control oil cylinder for an AMT gearbox dry clutch. Background technique: [0002] The clutch control in the automatic transmission control system is roughly divided into several types: hydraulic torque converter, wet clutch, dry clutch and so on. Due to the large transmission torque of commercial vehicles, dry clutches are often used. However, the existing dry clutch oil cylinders still have problems such as high processing difficulty, low control accuracy, and poor consistency. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. Invention content: [0004] The object of the ...
