Based on independent innovation, carbon particle material double cone ring is available in Tianhai

A synchronizer double cone ring made of carbon particle material, which is a new type of friction material, was successfully launched in Tianjin Tianhai Synchronizer Co., Ltd. According to the authoritative organization, the performance of this double cone ring is better than that of similar foreign products, and the manufacturing cost is low, which can completely replace the import, thus breaking the monopoly of foreign products.

Tianhai Synchronizer Co., Ltd. is the largest synthesizer research base in China. It has been well-known for its independent research and development of a variety of synchronizers that fill the domestic gap and reach the international advanced level. The domestic market share is as high as 70%, and it also plays an important role in the international market. Last year, Shaanxi Fast Gear Co., Ltd. and the company had a cooperation project, which required the use of the special sintered copper alloy double cone ring of the German HOERBIGER company. When the company went to purchase this expensive double cone ring to prepare for the package, it was rejected. The reason is simple. HOERBIGER has entered into a joint venture with Taizhou Dongfang Synchronizer Co., Ltd., thus blocking the patented product belonging to HOERBIGER. In the face of the technological monopoly and product blockade of foreign companies, Tianhai is determined to use its scientific research advantages and take a different approach. It uses a new type of friction material, namely carbon particle material, to independently develop a new generation of double cone ring. To replace the double cone ring of sintered copper alloy material.

Later, it proved that the company not only succeeded in developing a double-cone ring of carbon particle material, but also had a friction coefficient higher than that of a sintered copper alloy material double-cone ring, and it was used for a synchronizer of the same diameter, and the synchronous capacity was larger. After 200,000 shifting experiments, the carbon particle material double cone ring still has a wear margin, the synchronizer has not failed, and its quality has completely reached the international advanced level.
