Description

Technical Field

[0001] This utility model relates to the field of friction braking structure technology, specifically to a clutch assembly employing an elastic separation structure. Background Technology

[0002] The clutch, installed between the engine and the transmission, is an assembly in the automotive drivetrain that is directly connected to the engine. Typically, the clutch is mounted together with the engine crankshaft flywheel assembly, serving as the component that cuts off and transmits power between the engine and the drivetrain. Throughout the entire process from starting to normal driving, the driver can operate the clutch as needed to temporarily separate or gradually engage the engine and drivetrain, cutting off or transmitting power from the engine to the drivetrain.

[0003] The driven disc hub clutch, also known as a friction clutch, is the most widely used and oldest type of clutch. It basically consists of four parts: the driving part, the driven part, the clamping mechanism, and the operating mechanism. The driving and driven parts and the clamping mechanism are the basic structures that ensure the clutch is engaged and can transmit power, while the operating mechanism is mainly the device that disengages the clutch.

[0004] If there is no clutch between the engine and the load, the engine will generate a large inertial force upon starting, creating a huge resistance torque that causes the engine speed to drop sharply or even stall. If a clutch is provided during startup, it can first be used to separate the engine from the gearbox, and then the clutch can be gradually engaged while increasing the throttle, gradually increasing the torque transmitted through the clutch. Another function of the clutch is to ensure smooth transitions between operating conditions. Without a clutch during emergency braking, the enormous inertial force would overload the transmission system, affecting not only the transmission mechanism but also potentially damaging engine components.

Separator ear plates are provided between the upper and lower elastic separation components and the pressure cover, respectively.
