-wrap-mode: nowrap;">Clutch Disc  serves as the core friction component of the clutch assembly. Key information is as follows:

Core Function

Sandwiched between the flywheel and clutch pressure plate, it transmits engine power through friction between its friction surfaces. During engagement, it is compressed by the pressure plate and rotates synchronously with the flywheel. During disengagement, it separates from the pressure plate to interrupt power transmission, facilitating gear shifting operations.

Compatible Models & Parameters

Compatible Models: Heavy-duty trucks including Sinotruk Howo, Shaanxi Delong, Dongfeng Tianlong, etc.

Common Specifications: Diameter matches pressure plate (typically 380mm/430mm); spline teeth count usually 10 teeth/12 teeth (matches transmission input shaft); torque capacity matches pressure plate (2000N・m and above). Product Features

Structure and Materials:

Friction Plates: Utilize ceramic/copper-based composite materials offering high wear resistance and heat tolerance (operates above 300°C);

Steel Core and Buffer Structure: Steel core provides structural support, while internal torsion springs (buffer blocks) absorb transmission impact to reduce shift shock.

Operational Characteristics:

Wear on friction surfaces causes clutch slippage, necessitating periodic thickness checks (typically worn to 1/2 original thickness);

Fatigue failure of buffer springs may induce abnormal shift noises.

Maintenance Key Points:

Typically replaced as part of the “clutch three-piece set” alongside pressure plate and release bearing;

Align spline directions during installation to prevent abnormal power transmission from incorrect orientation.
