Whether it is a commercial vehicle or a passenger car, the role of the transmission shaft is indispensable. A transmission shaft refers to a tubular shaft or solid shaft with universal joints, or an assembly directly connected by two universal joints to transmit torque and rotational motion, consisting of a shaft tube, a telescopic sleeve, and a universal joint. Its dynamic balance is crucial. Generally, the transmission shaft needs to undergo a dynamic balancing test before leaving the factory and be adjusted on the balancing machine.

The transmission shaft can cooperate with various accessories on the car to maintain high-speed rotation for a long time, ensuring the high-speed and safe driving of the car. During the process of driving, cars inevitably encounter various rough and uneven road conditions, which can cause the car to bounce and result in changes in load. As a result, the angle and distance between the transmission output shaft and the main reducer input shaft will also change accordingly. At this point, the universal joint on the transmission shaft can ensure that in such road conditions, when the relative position between the transmission output shaft and the input shaft of the main reducer changes to a certain extent, power can still be transmitted normally and reliably. In addition, the universal joint can also ensure that these two shafts can operate evenly.

Commercial Vehicle Transmission Shaft: Multiple Factors Ensure Medium - to Long Term Market Prosperity for Heavy duty Trucks
Driven by the policy of phasing out heavy-duty trucks in China. On July 3, 2018, the central government issued the "Three Year Action Plan to Win the Blue Sky Defense War", and on January 4, 2019, the Ministry of Ecology and Environment and eleven other departments jointly released the "Action Plan for the Battle against Diesel Truck Pollution Control". Propose to phase out more than 1 million medium and heavy-duty diesel trucks with National III emission standards or below in the Beijing Tianjin Hebei, Fenwei Plain and surrounding areas by the end of 2020. As of the end of 2018, the number of heavy-duty trucks under the "Three Guarantees" in China was 1.556 million, of which nearly 85% were heavy-duty trucks with a vehicle age of five years or more, indicating strong demand for updating the vehicles themselves.

Increased investment in infrastructure. Affected by the COVID-19 this year, the domestic and foreign trade situation declined significantly, and the economies of all countries suffered a heavy blow. Infrastructure construction has once again become an excellent means to boost the economy and increase employment in emergency situations. The progress of infrastructure construction will drive the demand for heavy-duty trucks in construction projects such as slag, concrete mixer trucks, and sand and gravel transport trucks in the near future.
In addition, due to the deepening of regulations such as overload management, the capacity of commercial vehicles has decreased. Faced with the continuous increase in logistics demand, the proportion of heavy-duty trucks in logistics has increased to 60-70%. In the medium and long term, the market demand for commercial vehicles, including heavy-duty trucks, will continue to increase.

The growth of heavy trucks is bound to drive the market for their required driveshafts. Among numerous commercial vehicles, the market volume of heavy-duty trucks occupies multiple parts of the entire market.

Passenger car transmission shaft: benefiting from the increased penetration rate of electric vehicles
Green environmental protection is an eternal global topic, and in the automotive industry, electrification of automobiles has become a trend of the times. The sales of new energy vehicles in China reached 12.15 million units in 2018, and are expected to grow to 7 million units by 2022, with an average annual compound rate of 34.2%; The sales of new energy vehicles in Europe reached 407000 units in 2018 and are expected to increase to 3.905 million units by 2022; The sales of new energy vehicles in the United States reached 358000 units in 2018 and are expected to increase to 1.7 million units by 2022. Driven by the trends of the Internet of Things and the Internet of Vehicles, the popularization of electric vehicles worldwide is just around the corner.

The profit of transmission shafts in the passenger car field is much higher than that in the commercial vehicle field. The passenger car sector will quickly become the world of electric vehicles, with higher torque requirements for the transmission shaft. The higher the torque requirements for the transmission shaft, the higher the product unit price and gross profit margin. Due to the working characteristics of the motor, its torque reaches its maximum at the moment of starting, while the fuel engine starts at a low speed and the torque gradually increases from small to large. Therefore, the impact of torque on the transmission shaft of electric vehicles will be greater.

The domestic constant speed transmission shaft market is mainly occupied by joint ventures or foreign-funded enterprises, mainly led by Shanghai Natifu, a joint venture between GKN and Huayu Automobile, with a market share of about 45%. The remaining share is mostly occupied by Japanese NTN's joint venture in China, Wanxiang Qianchao transmission shaft, and other smaller enterprises.

Henan Tongxin Transmission Co., Ltd., founded in 2001, is located in the Economic and Technological Development Zone of Xuchang City, Henan Province, covering an area of 80000 square meters. It is a national "specialized, refined, unique, and new" small giant enterprise and a national high-tech enterprise. And officially listed on the Beijing Stock Exchange on November 15, 2021.

The company has its own 'technology center', dedicated to improving product quality and constantly innovating technical processes. With over 40 patented properties, we have pioneered the forging of blank raw materials with "hollow cores and no waste edges" in the industry, and our technology has reached the international priority level. The company relies on advanced production technology, sophisticated equipment, efficient production organization capabilities, strict quality control system, and excellent full-service model; With the quality policy of "pursuing zero defects and satisfying customers", we aim to build our enterprise into a specialized transmission shaft service platform.

At the same time, with non constant speed transmission shafts occupying an absolute position, Far East Transmission sensitively sensed the business opportunity of constant speed transmission shafts for passenger cars and produced 2 million sets of passenger car constant speed transmission shafts in 2019, entering the passenger car field and opening up growth space. The new product of passenger car transmission shaft can be applied not only to fuel vehicles but also to new energy passenger vehicles. Due to the higher torque requirements of electric vehicles for transmission shafts, the gross profit margin obtained is also higher. It is foreseeable that this batch of products will benefit from the development of electric vehicles to obtain higher profits. It is expected that the production capacity will reach 3 years old, with a revenue of about 1 billion yuan and a profit of about 120 million yuan.

The domestic constant speed transmission shaft market is mainly dominated by joint ventures or foreign-funded enterprises, with most of their technological cores located overseas. However, many domestic companies in the industry have diversified their businesses and their focus is not on the transmission shaft market. Far East Transmission relies on the dual tube drive of constant speed transmission shafts and non constant speed transmission shafts, as well as its unique local advantages, to gain more market share and is expected to break the pattern of the constant speed transmission shaft industry, becoming a pioneer in the entire transmission shaft field.
