离合器片

A clutch disc is a friction component in clutch-brake systems that engages and disengages power transmission between rotating shafts.

技术定义与适配语境
典型 离合器片 会按材料、尺寸公差、适配关系和失效风险在 汽车制造 中评估。

The clutch disc is a critical friction component in mechanical clutch-brake systems, consisting of a steel core plate with friction material bonded to both sides. It transmits torque from the driving shaft to the driven shaft when engaged under pressure from the pressure plate, and allows disengagement when pressure is released. The disc includes torsional dampers with springs to absorb vibration and shock loads during engagement.

定义
The clutch disc is a critical friction component in mechanical clutch-brake systems, consisting of a steel core plate with friction material bonded to both sides. It transmits torque from the driving shaft to the driven shaft when engaged under pressure from the pressure plate, and allows disengagement when pressure is released. The disc includes torsional dampers with springs to absorb vibration and shock loads during engagement.
工作原理
The clutch disc operates on friction principles. When the clutch is engaged, the pressure plate forces the disc against the flywheel, creating friction that transmits rotational force. When disengaged, the pressure is released, allowing the disc to separate and interrupt power transmission. The torsional damper springs absorb rotational irregularities to ensure smooth engagement.

常见问题

What causes clutch disc wear?

Clutch disc wear is primarily caused by friction heat, abrasive particles, improper engagement (slipping), and contamination from oil or grease.

How do I know when to replace a clutch disc?

Replace when experiencing slipping (RPM increases without acceleration), burning smell, difficulty shifting gears, or visible wear below minimum thickness specifications.
