Hunan Rongda Intelligent Transmission Co., Ltd.

Rongda was founded in November 2003 and is a nationally recognized high-tech enterprise, a key enterprise of Hunan Province, and a Hunan Province Double Hundred Project enterprise. In 2017, Rongda became a subsidiary of Chongqing Sokon Industry Group. Chongqing Sokon Industry Group is a physical manufacturing enterprise with engines and new energy vehicles as its core business and complete vehicles as its main business. It is one of China's Top 500 Private Enterprises, Top 500 Chinese Manufacturing Enterprises, Top 500 Chinese Machinery Enterprises, and an A-share listed company.
The company is mainly engaged in the R&D, production, sales, and technical services of automotive continuously variable transmissions (CVT). The company currently has nearly 400 employees, including nearly 100 in technical R&D, and more than 20 technical personnel with doctoral degrees or senior professional titles. Over the years, the company has adhered to independent R&D and technological innovation, and has overcome all key technologies for the industrialization of continuously variable transmissions. The CVT developed by the company has completely independent intellectual property rights. Key technologies such as the "metal belt type continuously variable transmission digital electro-hydraulic control system" have obtained more than 50 national patents.
The company's current main products include traditional internal combustion engine CVT gearboxes and CVT-based hybrid transmissions HCVT (platform under development).
The mass-production platform products of traditional internal combustion engine CVT transmissions are the company's RDC15 and RDC18 products and the upcoming mass-produced RDC27 product: the RDC15 product was independently developed by Rongda and won the title of "National Key New Product"; the RDC18 product was jointly designed and developed with Bosch Transmission Technology Co., Ltd. This design applies a variety of advanced CVT application technologies fully verified by Bosch, and the product allows *** input torque to reach 180Nm; the RDC27 product is the company's third-generation CVT product, and the product allows *** input torque to reach 270NM. The application of various new technologies can further reduce fuel consumption, achieve a lower lock-up vehicle speed, and have lower hydraulic losses. Mass production is planned for early 2019.
Development of CVT-based hybrid transmission HCVT: Since 2012, the company has successively carried out project cooperation on hybrid transmission module development with Dongfeng Nissan, Chery, Lifan Auto, Dongfeng Sokon, etc., and has undertaken project development and research topics for hybrid CVT such as the National 863 Program and the Science and Technology Bureau Technology Promotion Special Project. It has accumulated rich development experience and research results in the field of new energy vehicles and can provide OEMs with hybrid and electric drive transmission products based on P2, P4, and other solutions.
The company currently has two production bases, the Changsha production base and the Luzhou production base under construction. The first phase of the Luzhou base is planned to be put into production within 2018, and after production, the annual capacity can reach 150,000 units/sets. The second phase is planned to be put into production in 2019, and after production, the annual capacity can reach 500,000 units/sets.
