German Industrialization Thinking from ZF
Speaking in Germany, people can not help but always as a "technology leader" and other titles, while talking German ZF (ZF), it is also unique in the commercial vehicle chassis and drive technology.
Merkel officially visited China on July 7, 2014. On the same day, the Chinese professional press team was invited to visit the ZF Group. This made our experiential activities and interviews more meaningful. A whole day of test drive activities, a full day of visits, reporters from the product and manufacturing aspects close to the "technology, leading" mystery, enjoy the "technology, leading" the truth.
ZF was founded in 1915. The auto parts giant used nearly a hundred years to prove its ability to provide close-range high-quality products and services for all regions and all levels. According to the 2013 Annual Complete Report, ZF has 72,600 employees in terms of company scale, with global sales reaching 16.8 billion Euros. ZF has 122 production models in implementing its localization strategy. The company is distributed in 26 countries around the world; after-sales service, ZF has 32 service companies in 77 locations worldwide, 5 market office locations, 72 logistics centers, and more than 650 service agencies. In terms of after-sales service network and technology research and development, ZF has established 8 R&D centers and 6,244 elites in the company's R&D team. Each year, 5% of sales are invested in R&D (2013 R&D investment was 836 million. Euro), supporting the Group's development testing and application upgrades at the frontier; In the commercial vehicle sector, the company produced a total of 521,000 transmissions , 10 million shock absorbers, and 10.4 million chassis components throughout the year. Behind the series of figures is the super strategic power of super multinational companies such as ZF. This is a model of a specialized and diversified enterprise group.

In 2014, ZF made further progress in chassis and transmission technology. ZF's new product experience test drive was conducted at the university test site in Aachen, Germany. Despite the heavy rain on the day of the test drive, it did not stop people's interest and curiosity about ZF's advanced technology. At the event site, every ZF staff member meticulously completed the established workflow and everything was done step by step. The China Truck Network reporter is concerned about the development of the latest technologies in the chassis and transmission of commercial vehicles. The following are the key technical points and test drive experience of key driving products for sharing.
Focus on innovation and seek solutions for sustainable transportation in the future
In the course of the event, ZF is almost the bulk or even the only supplier of all world-class commercial vehicles. As an independent supplier of spare parts, ZF stands out by effectively preventing the development of its own parts and components of the entire vehicle company. The product is excellent quality and strict control over cost. ZF believes that only relying on quality and competitive price can maintain the strong position of third-party suppliers. This pattern undoubtedly reflects ZF's advanced industrialization thinking and systematic ability. .
ZF commercial vehicle technology is working hard to provide sustainable transportation solutions for the future. ZF is deeply aware that commercial vehicles are now facing increasingly complex tasks. For fleet operators, economics and reliability must be sufficient and necessary conditions; for global sustainable transportation, energy saving and emission reduction is a public mission; for drivers and passengers, it is a prerequisite for vehicles to ensure safety. Next, improve comfort. ZF's continuously leading transmission and chassis technology, customized electronic equipment, lightweight design concepts, and innovations derived from intelligent network systems ensure that current and future vehicles meet the above objectives, and these goals have already been tested. The field is realized.
ZF TraXon Hybrid Electronic Control System
ZF's global innovation, TRA-XON's modular gearbox system, provides a versatile and flexible solution for a wide range of applications, as well as a dual clutch module for heavy-duty trucks that provides no power to the shift process , driving feels very smooth. TRAXONHYBRID can apply hybrid technology for long-distance transportation. In the TRAXON HYBRID system, the motor in the clutch housing achieves braking energy recovery, purely electric operation, and shutting down the engine to assist the engine. Hybrid modules are particularly attractive for many applications. When the generator is running, it can integrate the energy of other components into other applications, such as refrigerated transport. TRAXONHYBRID can also introduce a "slide" function to recover energy for secondary use during braking.
ZF does not view transmission, chassis, steering technology innovation as a stand-alone solution, but instead focuses on the joint intelligence network to achieve maximum added value. ZF Concept Truck for Experimentation, Integrating TRAXON Hybrid System, SERVOTWIN Steering System and Telematics Solution on 25.25m Long Trucks, including semi-trailers and trailers, via tablet or smartphone, moving fingers You can control large trucks and realize driverlessness in the real world.
In all product combinations, ZF has adopted a lightweight structure in the chassis, including front and rear axle systems, various control arms, vibration damping modules and systems, and cab suspension systems, using alternative materials and functional integration To achieve the purpose of lightweight.
The low-floor bus system is a key component of the city's bus transport solution. The RL82EC is a self-suspended front axle. The AVE130 electric rear axle can be combined with series hybrid, trolleybus, battery or fuel cell energy design solutions. Through the application of the AVE130 electric gate bridge, ZF has achieved unimaginable achievements in the past - zero-emission urban bus, AVE130 maximum load of 13 tons, generator maximum power output of 2 * 120 kilowatts. Up to now, 300 electric gate bridges have accumulated over 10 million kilometers in the past few years, which is enough to prove that they can be put into daily use. The first batch of AVE130 electric gate type axles were built by German Mercedes-Benz EVOBUS and China Foton Ouhui. New Energy Bus and the Turkish BOZANKAYA electric drive bus. ZF's technological innovation and leading products are far more than that. It is because of the continuous technological innovation spirit that ZF maintains its strong global competitiveness.
Keep improving, ZF sticks to the spirit of Germany
Schweinfurt, more than 100 kilometers from Franconia, has a SACHS plant under the umbrella of ZF, a logistics center and an R&D center, which is the most representative outside ZF headquarters in Germany. In the industrial base, one can feel ZF's employees being so dedicated and rigorous.
ZF TraXon module
In the SACHS torque converter factory assembly plant, six production lines started at the same time, and the huge assembly shop did not see too much head shaking. The Germans seemed to be more willing to use the "lazy" way to allow more processes to be completed automatically in the setup process, or With robots to complete relatively complex operations. It looks like everything in front of you is simple, but behind it is hundreds of complex debuggings.
In Schweinfurt's logistics center, there is an automated packaging line and bar code management system, as well as a three-dimensional storage center, unmanned management warehouse, there is a bar code everything, what you want to get. The Germans are fond of machines, where machines are unmatched for the ability to precisely control and precisely select.
In the R&D center, the crowd is much denser. After all, this is an area that really depends on the mind to produce results. The lab displays a product model that looks uncomplicated. The staff introduced to us that the ultimate simplicity is the mission of ZF researchers. On the surface, everything seems very simple. A shock absorber and a clutch disc spring come from very simple mechanical principles. Here, every molecule has been studied, from the metallic mirror phase to the oil's quality viscosity, and more importantly, these quasi-products have experienced hundreds of thousands of undifferentiated fatigues throughout the life cycle in dozens of days. The purpose of the test is to ensure the quality and stability of the loading application.
Remote control driving future truck
This kind of technical superiority or production habits can hardly be duplicated. This is due to the fact that the Germans have a well-deserved habit and meticulous nature. It is this rigorous and almost stubborn spirit that allows them to tirelessly carry out simple and cumbersome trial and improvement, dismantling complex technical problems into simple ones, but so-called simplicity is essentially step by step and methodical. In modern manufacturing, details determine success or failure, and precision determines quality. Regarding ZF, both details and precision come from the German spirit of the company. To do simple things, make things easier, and copy the streamlined products in large quantities to make them stronger.
ZF is not a company fighting, and German manufacturing is a spiritual, meticulous spirit. However, the German spirit of ZF is not completely impossible to duplicate. Chinese companies should not only insist on the use of product or technology in the process of cooperation with ZF. What is more important is to persist in studying ZF’s rigorous and precise system capabilities, streamlining the replication of modern industrial thinking and the meticulous German spirit. In this way, China's manufacturing industry can shift from a lagging "Made in China" to an earlier "China-made", making our great country stand firmer in the world of powerful nations.
