Because it is the same 7 -seater MPV, many people on the Internet joked that Baojun 730 is the “upgraded version” of Wuling Hongguang S. It believes that Baojun 730 will “follow the trend” with the chassis structure of Hongguang S. However, after some of our field disassembly, we got a very different answer from speculation.
I wanted to see the 730 sub -frame structure, but the problem came … Previously, when the four masters and apprentices went to Tibet, the 730 was equipped with a steel guard plate. This guard has played a key role in the Tibetan journey. In the upcoming 20,000 kilometers of maintenance, we will let it go to the field to relieve the armor, and then give you an introduction to the auxiliary frame.
The front suspension part of the Baojun 730 is shown in the figure above. 1 is the lower control arm, 2 is a steering section, 3 is a horizontal anti -tilt rod, and 4 is a spring shock absorber.
There is a hard connection between the front auxiliary frame and the body. Even a car similar to a car, it is hard to see that it will be connected with a pad.
There is no transmission shaft in the middle position. This is the biggest example of Baojun 730 is not a Hongguang S upgraded version. Baojun 730 has adopted the front wheel drive. In the field of cars, rear drives often symbolize high -end, but for Economy MPVs of less than 100,000 yuan, the significance is very different. In addition to the loss of the rear drive, there is not much power, and a bigger problem is still the transmission shaft shake. Our previous Wuling Hongguang S had such problems. We need to deliberately use the accelerator and gear to avoid the speed of falling below 2000 to reduce the shaft shaft. The staff made a decision between the jitter and noise, and the front -drive Baojun 730 did not have this problem.
Baojun’s post -730 suspension uses a drag arm structure. One of the places that reflect the sedan is to use spiral springs instead of steel plate springs. The steel plate spring has greater advantages in terms of load, but the comfort of the shock filtration is not as good as the spiral spring. We can glimpse the positioning of Baojun 730 from it. Previously, Wuling Hongguang S used the rear wheels, so the left and right wheels need to be connected with the overall bridge. Baojun 730 has no need to consider the transmission because the rear axle no longer needs to be considered, so he uses a drag arm to connect the left and right wheels. Theoretically, the overall bridge is a completely non -independent structure. Unilateral wheel beating will be directly transmitted to the other half, and the drag arm is a semi -independent structure. The drag arm will use slightly twisted Earthquake comfort.
Baojun 730 chassis also has two very sedanized places. One is that the position of the drag arm beam is before the left and right rear wheel connecting. This design is conducive to the drag arm structure to absorb unilateral wheels by distorting, thereby increasing the filtering to improve the filtering Earthquake comfort. On the other hand, the NV200 that was dismantled before, the beam is placed directly at the left and right rear wheel connection positions. This trailer arm is closer to the overall bridge in terms of characteristics, and the orientation is more oriented. ABS, more importantly, makes ESP equipment Baojun 730 possible.
As can be seen from the figure above, although the shock absorber has been penetrating to the end of the wheel vault, it has a small impact on the third row, and this position is also made by the manufacturer’s “taking the trend”.
Baojun 730 and Wuling Hongguang s have a common point. After using aluminum alloy wheels, the tires are too low. Baojun 730 tire specifications are 195/55R16. On the other hand, Irizer 7, who uses 16 -inch wheels with the same 16 -inch wheels. The wheels have reached 19.7kg, and Baojun 730 is only 16.5kg! Although Irizer’s 7 tires are width to 205, it is not as good as that of such a big gap.
Summary: This article is undoubtedly “car”. The problem that cannot be avoided in the end is undoubtedly whether the Baojun 730 chassis has the root to find? Judging from the details of various places, we boldly speculate that the 730 chassis is related to the 630 sedan, which is reflected in some layout design. Not to mention that the front McPherson trailer structure, some details of them are quite “similar”. For example, the rear suspension is that the spring is the front shock absorber, and the shock absorber directly extends directly to the wheel vault. The shape is also very similar.
