Explore SAIC Lingang Factory and see how Roewe RX5 MAX was born from parts to complete vehicles.

Text: Qu Peng who knows how to drive fast.

On the first anniversary of the listing of Roewe RX5 MAX, SAIC held a factory exploration activity in Lingang production base, which was a very rare opportunity to see the assembly process of a RX5 MAX from parts to the whole vehicle at close range. In the past activities, filming was not allowed inside the factory. This time, it is an exception, which can give everyone a chance to feast their eyes.

Established in 2007, SAIC Lingang production base is the most modern automobile production base in China. Located in the heavy equipment industrial zone of Lingang New Town, Pudong New Area, Shanghai, it covers an area of10.2 million square meters and has an annual production capacity of 570,000 units. It has four workshops: stamping, body painting and final assembly, and 1 engine factory.

Our visit mainly includes two parts: body workshop and assembly workshop. The first is the body workshop, covering an area of 63,289 square meters. The interior of the workshop is designed as an upper and lower two-story structure. There is a machine transport storage area and a conveying line in the air, and the welded components are conveyed through the air machine conveying line.

The car body is the main part of the car, and the car body workshop is mainly engaged in welding different shapes of sheet metal parts into a white body by welding assembly.

At present, the body-in-white of the best-selling Roewe RX5 model on the market consists of more than 20 small parts, which are reinforced by welding 237 1 spot welding and 162 arc welding. You can also see a lot of neatly arranged body parts in the workshop, which is convenient for post-processing.

Because most of the body workshops are welding work, sparks are everywhere at the scene. We rode electric cars to browse in turn, and we could smell burning in the air. In order to ensure the safety of workers, a lot of protective work has been done around each station, and it is really not easy to present a clearer working state of the workshop.

Everyone is excited when browsing the open assembly unit, because this is the laser welding part that everyone often mentions. This station is also one of the most important stations in the whole workshop. The positioning accuracy and locking mechanism can meet the repeated accuracy requirements of car assembly. Nowadays, laser welding technology has been widely used in automobile manufacturing industry, which can be said to be one of the most famous technologies in automobile manufacturing industry.

After a series of processes in the painting workshop, the body-in-white that has passed the quality inspector's inspection will be sent to the body distribution center and submitted to the assembly workshop for assembly.

The construction area of the assembly workshop is 43,557 square meters, and the plane of the workshop is T-shaped. The whole workshop is divided into three areas: internal assembly, chassis equipment and assembly line performance test area.

In the assembly workshop, vehicle parts such as vehicle interior, powertrain, transmission mechanism and seat tires will be installed. Every working procedure will be recorded in real time in the background to ensure that every mechanical part is installed in strict accordance with the specified standards.

In the workshop, we also saw a car with parts running on the track. This kind of car is called AGV car for short in automobile specialty. The parts on the car are all the internal parts needed to install the car.

After all processes are completed, the vehicle will enter the performance test area of the assembly line to check the data indicators of the vehicle and the status of parts under various working conditions.

In the last step of checking the vehicle, the equipment will simulate the maximum rainfall that will be encountered in real life, spray the vehicle body from different angles, and test the overall tightness of the vehicle. The feeling I saw at that time was that it was really interesting that the vehicle went into the "shower" after completing all the processes performed in the production process and then left the factory cleanly.

After visiting the factory, the manufacturer also arranged a simple test drive to experience the Roewe RX5 MAX produced from Lingang base.

Speaking of it, Roewe RX5 MAX has been on the market for one year, and everyone will not be too strange. You can often see it on the road. The whole car uses a lot of straight lines, which is very tense. From the side, the proportion of the car body is also relatively coordinated, and the overall style is masculine and tough.

Entering the car, Roewe RX5 MAX performed very well in terms of space. Whether in the front row or the back row, vertically or horizontally, it is very easy to meet the needs of the whole family.

In terms of configuration, I mainly talk about a few highlights. Roewe RX5 MAX test drive car is equipped with 12.3-inch full LCD instrument, which can support panoramic AR navigation. Zhongkong has a large curved screen of 14.3 inches, which is said to be the best screen technology in Roewe history. The lathe system is based on the solution provided by Zebra Zhixing. This system is well known, and it performs very well in speech recognition and easy operation.

What's even more surprising is that there are as many as 256 kinds of color changes of the ambient lights in the car, which is in line with the BOSE sound in the car to create the atmosphere in the car.

In the power system part, the Roewe RX5 MAX which was tested today adopted a blue core 2.0T direct injection turbocharged engine, which matched with a 6-speed wet dual clutch gearbox. This engine is independently developed by SAIC, which fully meets the emission standard of National Sixth B, with maximum power 170 kW and maximum torque of 370 Nm. At present, among the domestic independent brands, the 2.0T turbocharged engine has such a torque numerical performance, which can be said to be very strong.

During the test drive, I feel that the power output of the engine is really abundant, and the acceleration in the middle and rear sections is completely no problem. The foot feel of the accelerator is sensitive, and the performance in the initial stage is relatively light. Roewe RX5 MAX adopts ultra-high strength steel cage body, and the overall high strength steel accounts for 88%, which is very safe, but it doesn't feel heavy when driving because of the body, and it is still very easy to use.

It is obviously a comfortable orientation in chassis vibration filtering. I believe many people will prefer this kind of training. When crossing the pit or speed bump, the suspension has no unnecessary bounce and the performance is very crisp. Roewe RX5 MAX vehicle adopts sound insulation materials in a large area. The data show that the coverage rate reaches 95%, and the front windshield and front window are made of double-layer sound insulation laminated glass, and NVH is well controlled. In general, it is the feeling of leaning towards a comfortable urban SUV.

After completing the exploration of the whole factory, I really gained a lot of new knowledge about the Roewe RX5 whole car series. In fact, compared with foreign countries, the manufacturing technology level of domestic independent brands can be said to be the same level, and even in individual technical indicators, we will be more stringent.

I also learned from the communication with SAIC technicians that they are still further studying how to control the technical error smaller. At the present stage of technological development, even reducing the error of 0. 1 mm is as difficult as climbing a mountain. But in these engineers, I can really feel the persistent craftsman spirit. I believe that in the future, Roewe brand will launch more excellent works, and we look forward to it together.
