Today, most widely used synchronizer rings (SNRs) are made of brass (brass SNR). The development of superior SNR to brass SNR has been required for both shift feeling and durability, which are two important requirements for SNRs. Carbon-based friction material (carbon material) is selected to develop superior friction material to brass because carbon material is one of the most durable materials for an application of clutch and brake. Carbon material is placed on the friction surface of SNR (carbon SNR). The structure of carbon material, kinds of raw materials and their combination ratio are selected and optimized. The carbon SNR is confirmed to have higher performance than brass SNR for both shift feeling and durability. At present, our carbon SNRs have been introduced into pickup trucks and SUVs in USA.
