Description

Clutch driven disc of large bulldozer

Technical Field

The utility model relates to a friction disc technical field, concretely relates to large-scale bull-dozer clutch driven plate.

Background

The clutch driven disc hub is also called friction clutch, is a clutch which is widely applied and has the longest history, and basically comprises a driving part, a driven part, a pressing mechanism and an operating mechanism. The driving part, the driven part and the pressing mechanism are basic structures for ensuring that the clutch is in an engaged state and can transmit power, and the operating mechanism of the clutch is mainly a device for separating the clutch.

The friction clutch is generally positioned between the engine and the gearbox, or is combined with the gear to form a gearbox assembly with clutch and forward and reverse functions, and is a main part connected between the engine and the shafting. The output shaft of the clutch is the input shaft of the gear box.

In the marine machinery, if a clutch is not arranged between an engine and a load, a large inertia force is generated when the engine is started, and a large resistance moment is formed on the engine, so that the rotating speed of the engine is sharply reduced, and even the engine is flamed out. If the clutch is arranged during starting, the engine and the gear box can be separated by the clutch, then the engine and the gear box are gradually jointed while the accelerator is increased, the torque transmitted by the clutch is gradually increased, the propelling force of the ship is also gradually increased, and when the propelling force is greater than the driving resistance, the ship starts to move from a static state and gradually accelerates, so that the stable starting of the ship is one of the main functions of the clutch.

Another function of the clutch is to ensure smooth regime switching. Without the clutch, the huge inertia force can overload the transmission system when in emergency braking, which not only affects the transmission device, but also damages engine parts. In addition, the combination of the clutch and the gear can make the transmission device have a reverse function.
