(1) The wet multi disc friction clutch clutch assembly is immersed in engine oil, which is divided into three parts: driving, driven and separating. The clutch is a constant joint type. When the clutch handle is tightly pinched, the screw handle rotates the screw sleeve in the left cover through the steel cable. The adjusting screw in the screw sleeve is moved to the right, pushing the separating push rod and the gland, the spring pressure disappears, and the friction sign is separated from the driven plate.
(2) The structure of the automatic centrifugal clutch can automatically control the separation and engagement of the clutch according to the speed of the engine. The clutch is composed of driving, driven and separating engagement mechanism. The active part is composed of clutch cover, thrust plate, clutch plate, etc. The driven part is composed of friction plate, central sleeve, etc.
(3) The active part of the shoe type automatic clutch is a fixed seat driven by the crankshaft. There are three shoe assemblies on the seat, which are connected to the fixed seat with a pin shaft. The spring pulls the shoe toward the center of the crankshaft. When the rotating speed increases, the centrifugal force generated by the shoe is greater than the spring force, it will swing outward. When the centrifugal force reaches a certain value, it will be connected with the clutch disc, which will be driven by friction The driven part rotates to transmit power.
