What is the working principle of the agricultural machinery clutch?

The agricultural machinery clutch is a core component in the power transmission system of agricultural machinery. Its core function is to achieve the engagement and disengagement of power between the engine and the gearbox, ensuring that the power transmission can be flexibly controlled when the agricultural machinery starts, shifts gears, stops, or switches working devices. Its working principle is based on the dynamic cooperation of "frictional engagement" and "mechanical disengagement", which can be divided into the following key links:
I. Basic Structure and Core Components
The agricultural machinery clutch mainly consists of the active part, the passive part, the pressure mechanism and the control mechanism:
The active part: It is connected to the engine crankshaft and includes the flywheel, pressure plate, clutch housing, etc., rotating synchronously with the engine.
The passive part: It is connected to the input shaft of the gearbox. The core is the driven disc with friction plates, which can rotate and transmit power driven by the active part.
