At the 2013 Shanghai Auto Show, ZF introduced its innovative passenger car transmission and chassis technologies. These technologies not only reduce vehicle fuel consumption, but also increase driving safety and flexibility. ZF Group continues to introduce the latest production technology into the Chinese market and gradually realizes the continuous growth of its business in China. ZF's 2012 financial report shows that its sales in China reached 2.1 billion euros (about 17 billion yuan), an increase of 22% over the previous fiscal year. In 2013, ZF will continue to consolidate its market position - the Beijing-based passenger car axle system production base will be officially opened. ZF exhibited at the Shanghai Auto Show an 8-speed automatic transmission suitable for longitudinal engine models and the world's first 9-speed automatic transmission suitable for the transverse front drive model. The two modern, efficient transmissions are suitable for almost all passenger cars equipped with conventional transmission systems. In addition, as an expert in the field of transmission and chassis, ZF's electric torsion beams are a classic example of a highly integrated transmission and chassis function on the rear axle. This product is suitable for purely electric driven miniature and Small vehicle. "ZF attaches great importance to the performance of the product and its fuel economy, so in the next few years, ZF is expected to achieve sustained growth in the Chinese market." At the press conference of the Shanghai auto show, Jürgen Mr. Jürgen Holeksa, member of the board of directors of ZF Group, head of human resources and Asia Pacific, said: "To achieve this goal, in addition to establishing a new production base, we will continue to strengthen our presence in China. In addition, the Chinese market is also playing an increasingly important role in ZF's global technical service network. "The Chinese market is one of ZF's most important markets. ZF's sales in China account for about 12% of the group's total sales. To this end, ZF will continue to consolidate its market position in China, and more and more new products will be locally developed in the engineering center in Shanghai. ZF 9-speed gearbox ZF entered China in 1980. Today, ZF has 24 manufacturing companies in China, employs more than 5,000 people, and is expected to add another 1,000 this year. ZF Lenksysteme GmbH is a joint venture between ZF and Bosch in a peer-to-peer ratio. ZF's subsidiary in China is dedicated to China. The market offers high-quality products that meet the needs of the local market. ZF's business in China includes transmission and chassis technology for passenger cars, commercial vehicles, construction machinery and agricultural machinery, marine propulsion systems business and wind turbine gearbox business, and ZF (ZF) ) After-sales service in China business. ZF's customers include Chinese vehicle manufacturers and passenger and commercial vehicle customers of the global platform. ZF Shanghai Auto Show Booth Looking ahead to 2013, ZF's pace of development in China In addition, ZF's new passenger car axle system in Beijing will also be officially put into operation in 2013. With its capacity increase, ZF is expected to reach the annual production of thousands of axles, employ 350 employees, and supply mainly to Beijing Benz Automobile Co., Ltd. (BBAC). Mr. Jürgen Horeksa said: "As the scale of investment increases and the number of new customers increases, the importance of employer branding for ZF is increasing." Moreover, ZF ( ZF) pays more and more attention to the "localization of technology" project. During the project R&D process, ZF's Shanghai Engineering Center R&D will develop high-tech products specifically for the Chinese market, which will be produced by ZF in China. Base production. For this reason, the ZF R&D team in China needs excellent and creative talents. ZF will attract young Chinese engineers through a series of activities. For example, we have provided sponsorship for the Chassis Technology and Power Teaching Division of the Chinese University of Shanghai Tongji University and also sponsored the Tongji University Racing Team.

at the ZF Shanghai Auto Show Press Conference 
In 2013, ZF will maintain its active presence in the Chinese market through new cooperation programs and research and development of new products. For example, at the Shanghai Auto Show, ZF will sign a new agreement with China National Heavy Duty Truck Group. Under the agreement, ZF will supply the Ecosplit series of manual transmissions for CNHTC. Prior to this, ZF had provided its 16-speed Ecosplit transmission (model Sitrak C7H6x4) produced by the Hangzhou production base.
1. Regularly check the wear of the hydraulic cylinder seals, and if severe wear is found, it should be replaced in a timely manner.
2. Clean the hydraulic cylinder seals to prevent impurities such as dust and sand from entering the interior of the seals.
3. Use appropriate hydraulic oil and avoid using expired or non compliant hydraulic oil to avoid damage to the hydraulic cylinder seals.
4. Avoid using hydraulic cylinders under excessive pressure or load to avoid damage to the seals.
5. Regularly check the liquid level and pressure of the hydraulic cylinder to ensure its normal operation and avoid damage to the sealing components due to hydraulic cylinder failures.
6. When the hydraulic cylinder is stopped for a long time, regular maintenance should be carried out, such as applying anti rust oil, to prevent aging or deformation of the sealing components.
