Problems solved by technology

Among the clutches mentioned above, when the clutch is in the closed state, the torque is transmitted by the pressing force of the driving disc and the clutch pressure plate and the pressing force of the spring, so the transmitted torque is small, which cannot meet the needs of the tractor.

Abstract

The invention discloses a clutch which comprises a control unit, a clutch unit and a hydraulic input unit. The control unit comprises a control mechanism, a programmable logic controller (PLC) and a driving mechanism. The control mechanism comprises a control lever, a position sensor I and a light electric tachometer. The driving mechanism comprises an oil cylinder, a piston, a servo motor and a ball screw. The clutch unit comprises a clutch shell, a clutch cover, a clutch pressing plate, driving plates I, driving plates II, driven plates and a power output shaft. The hydraulic input unit comprises a hydraulic input end, an electromagnetic valve, a one-way check valve and an oil supplementing pipeline. The clutch system is not only large in transferred torque and capable of meeting using requirements of a tractor but also long in service life.

Description

technical field [0001] The invention relates to a clutch for a tractor. Background technique [0002] An existing clutch used on a tractor includes a clutch housing, a clutch cover, a driving disc, a clutch pressure plate, a driven disc, a spring and a separation mechanism. The separation mechanism includes a pull rod, a separation lever and a separation lever seat. The separation lever seat is arranged on the outside of the clutch cover, and the separation lever is mounted on the separation lever seat through a pin shaft. The pressure plate is connected, and the other end of the pull rod forms a flexible connection with one end of the separation lever. When the release lever is stepped on, the release lever pulls the pull rod to drive the clutch pressure plate to separate, and when the release lever is released, the pull rod returns to its original position and the clutch is closed. Among the above clutches, when the clutch is in the closed state, the torque is transmitte...
