摘要

摩擦衬片在长时间使用后状况恶化是离心离合器产生抖动的主要原因之一。摩擦特性可以通过在摩擦衬垫上产生特定的纹理或凹槽来保持。本文尝试用沟槽摩擦衬片研究离心式离合器的特性。以若干接触为基础,建立了离心式离合器的试验循环。实验使用了一个车辆试验台,其中开发的测试周期是自动化的。采用常规摩擦衬片和沟槽摩擦衬片对离心式离合器进行了100次循环试验,记录并分析了离心式离合器的性能特性。在本研究中,沟槽面积比保持为0.15,沟槽切割为90°。在完成100个测试循环后,带有沟槽摩擦衬垫的离合器表现出更好的特性。经过100次试验循环后,槽形摩擦衬板和法向摩擦衬板前缘的表面粗糙度分别降低了6.44%和8.11%。槽型摩擦衬板和普通摩擦衬板的前缘厚度分别减小了3.73%和4.98%。在整个100个测试周期的运行中,在带有沟槽摩擦衬垫的离合器的情况下,可以看到较高的离合器外壳温度。在第100个测试周期中,带沟槽摩擦衬套的离合器扭矩比普通摩擦衬套的离合器扭矩大15.22%。即使在长时间使用后,带有沟槽摩擦衬垫的离合器也表现出更好的抖动特性,并为车辆提供了更高的燃油经济性。

Experimental Investigation on Performance Characteristics of Dry Centrifugal Clutch with Grooved Friction Liners
The deteriorated condition of friction liners after prolonged use is one of the primary causes of judder in centrifugal clutches. The friction characteristics can be retained by generating specific textures or grooves on the friction liner. An attempt has been made to study the characteristics of centrifugal clutch using grooved friction liners. A test cycle for centrifugal clutch has been developed using a number of engagements as the basis. A vehicle test bench was used for the experiment where the developed test cycle was automated. The performance characteristics of the centrifugal clutch have been recorded and analyzed with normal friction liners and grooved friction liners for 100 test cycles. For this study, the groove area ratio was retained at 0.15, and the grooves were cut at 90°. After completing 100 test cycles, the clutch with a grooved friction liner exhibited better characteristics. After completing 100 test cycles, the surface roughness reduction at the leading section of the grooved friction liner and normal friction liner has been found to be 6.44% and 8.11%, respectively. The thickness reduction at the leading section of the grooved friction liner and normal friction liner has been reported to be 3.73% and 4.98%, respectively. Throughout the run of 100 test cycles, the higher clutch housing temperature has been witnessed in the case of a clutch with a grooved friction liner. At the 100th test cycle, the clutch torque with a grooved friction liner was 15.22% more than the clutch torque with a normal friction liner. Even after prolonged use, the clutch with grooved friction liner exhibited better judder characteristics and also provided higher fuel economy for vehicles.
