On April 20th, a 10-day 2014 (13th) Beijing International Automobile Exhibition was held at the new hall and old hall of China International Exhibition Center as scheduled. According to statistics, a total of 118 new cars were released for the first time at this year's Beijing auto show. Although the media’s numerous celebrities and fans’ positions have covered the auto show, auto show organizations have also been “voiced†by the crowd. In stark contrast to the entire vehicle exhibition area, few parts and accessories are patronized.
Through reporter observation and interviews, many new products and new technologies can still be found in the relatively deserted spare parts exhibition area, especially the new foreign-funded parts exhibition area. Among them, the three major trends of energy saving, electrification, and interconnection may be able to summarize the development trend of parts and components. "We are very optimistic about the development of China's auto market." In communicating with participating foreign-investment parts companies, a number of foreign-funded parts and components companies have expressed their attitude of attaching importance to the Chinese market and have expressed their intention to plan for the Chinese market in the next few years. Achieving rapid growth in market size and sales.
Energy saving in the end will be <br> <br> current, energy conservation has become a major issue worldwide automotive industry, technology research and development. In recent years, there have been many valuable breakthroughs for energy-saving and emission-reduction components and parts companies. In terms of engines, for example, direct-injection cylinders, turbochargers, optimized intake and exhaust designs, and lightweighting of other parts and components Design and other means, thereby reducing the weight of the vehicle, improve work efficiency, in order to achieve energy-saving emission reduction purposes.
In this year's Beijing Auto Show, many parts and components companies in the "to the end of energy conservation and emission reduction" attitude, in many "humble" parts and articles. Among them, Jettatek, NSK, and NTN will focus their efforts on energy-saving and emission reduction into the bearings of powertrains, drivetrains, and driving systems. The technical staff at the NTN booth stated that although the bearing is insignificant, it can help reduce the fuel consumption of the entire vehicle by optimizing its structure and working process.
So, how do small bearings achieve energy saving and emission reduction? Taking the timing chain of the engine as an example, through the timing chain and timing chain guide rails designed by the low-friction concept, the existing chain sliding process is transformed into a rolling process, and a number of low-resistance bearings are arranged on the timing chain guide so that positive When the chain moves more smoothly. According to the test data, when the oil temperature is 80 degrees Celsius, the timing chain with low-resistance bearings can reduce the average frictional resistance by about 20% compared to the existing products. Low-resistance bearings are used not only in engine timing mechanisms, but also in wheel bearings and transmission inner bearings. At the booths of these companies, there are demonstration devices that allow visitors to experience bearing resistance. Through practical experience, they can really feel the reduction of resistance.
In addition, the current start-stop technology is also constantly improving. BorgWarner brings the latest start-stop accumulators, which, through hydraulic energy storage, enable the start-stop technology to achieve faster filling and discharge of oil, ensuring low leakage at shutdown and high flow at start-up. With low noise and small size, it can be flexibly arranged inside the transmission or in the engine compartment. The start and stop of the accumulator application will enable the start-stop technology to have a faster response speed and a smoother ride experience. .
The timing chain reduce the frictional resistance of electric <br> <br> trend in recent years, pure electric vehicles as the representative of the new energy vehicle development continues to accelerate, either Tesla or domestic brands introduced a variety of new energy vehicles. Although many industry experts said that the arrival of the era of electric vehicles is still too early, but at this stage, more and more parts into the characteristics of electrification, electrification.
At this year's Beijing Auto Show, among the exhibits of foreign-funded parts and components companies, there were also a few products that involved motorization. As the world's first company to develop and mass-produce an electric power steering system (EPS), the company has exhibited EPS products that are suitable for various types of vehicles in nearly one-third of the booth area. According to the forecast of the Czech company, with the development of new energy vehicles, it is expected that after 4 years, 70% of global passenger vehicles will be fitted with EPS.
Tesla delivered new cars to the first batch of car owners during the show, and at the show, BorgWarner exhibited the eGearDrive, an upgrade of an electronically-driven transmission bridge fitted to Tesla vehicles. The transmission of a conventional car is difficult to adapt to the characteristics of an electric car. The electronic drive transmission bridge exhibited at BorgWarner incorporates features suitable for an electric car. The lightweight design, aluminum die-cast housing, and the maximum reduction in size are convenient. The entire vehicle is arranged. Peak torque of 400 N·m can be achieved, with a maximum speed of 14,000 rpm and up to 97% transmission efficiency and excellent NVH performance.
JTEKT EPS products interconnected car is no longer just car <br> <br> With the development of car networking, networking concepts, many vehicle and parts companies have also joined the field of automotive Internet, various kinds of launch Samples of new automotive interconnected products. The trend of interconnection is more integrated with automation. Perhaps in the future, the car will be more than just a car. The driving process does not have to be completely controlled by the driver. It may be integrated with other things in the day-to-day life.
In the most obvious position on the electric booth, the latest generation of the "interactive cockpit" of Denso is placed. Through the combination of various sensors and HMI (Human-Computer Interaction) technology, the electrical installation in the automotive communication system V2V, V2X, V2I has taken another step in three areas. The cockpit changes between the "interactive cockpit" and existing vehicles are not very big, but the changes are mainly reflected in the subtleties, such as body condition detectors on the steering wheel, head-up displays, electronic rearview mirrors, and communication robots. The body condition detector will monitor the heartbeat and pulse changes of the driver in real time to ensure the safety of driving; the head-up display and the electronic rearview mirror allow the driver to focus on the situation of the road surface without having to perform large movements to observe the surrounding environment; The communication robot is the way for HMI technology to carry out human-computer interaction. Through lighting and voice prompts, as well as the driver's voice control, driver assistance functions will be better provided for the driver.
Realizing vehicle-to-vehicle communication is an important link in the networking of vehicles. Bosch exhibited the Interconnected Control Unit (CCU) for communication solutions launched by fleet operators, connecting vehicles via on-board buses, monitoring vehicle operating data, helping operators to improve fleet management and reducing operational risks; Bosch's mySPIN is for smartphones The solution provided by the car owner directly projects the APP in the smart phone on the display screen of the car entertainment system so as to achieve safe and easy operation and control of the APP. The technology is also compatible with Apple and Android systems. Today, the popularity of smart phones, the integration of smart phones and vehicles, it also gives the attributes of automotive mobile Internet.
