Some time ago, Chery’s electric drive rear axle was compared and determined to be the rear suspension structure of the T1D plug-in hybrid version. Later, the rear suspension structure of Chery New Energy’s eQ5 was photographed, which can completely exclude the eQ5. It shows that the previous comparison judgment is correct, and now there is an updated patent application information exposed. This time it is not an invention patent, but a utility model patent. However, the entire rear axle and swing arm shape are completely consistent with the T1D plug-in hybrid version. , from invention patents to utility model patents means that practicality has reached the mass production stage, which also proves that the last analysis is completely correct.
Judging from the patent application drawing, it is indeed an H-shaped swing arm structure. When viewed from the rear, it looks like a smooth eggplant shape. Only when you look down can you clearly see that it is an H-shaped arm.
When I wrote before, I mentioned that the lower swing arm structure is made of aluminum alloy. In addition to the aluminum alloy, there is another doubt, that is, why there is no hollow structure to reduce the weight. Now that I look at the inner structure, I am relieved. Pay attention. The two red circles in the picture above do have a hollow design to reduce weight. Others are eager to put them visible to the naked eye. Chery is so good that they put them directly on the inside, for fear that others can see them. It can be seen from the patent application information: The purpose of this utility model is to provide an H-arm assembly structure for an automobile suspension with good stiffness and light weight, which includes an integrally formed body with two inner ends of the body protruding inward. There is a subframe connection part, and steering knuckle mounting parts are protruding outward at both outer ends of the body. The body is in an arc shape with a high rear end and a low front end, and the low position forms an area to avoid the transmission shaft. In the above scheme, the body is arranged in an arc shape with a high front end and a low rear end. The high and low arrangement of the body itself provides space to avoid the transmission shaft. There is no need to open a groove on the body, so the rigidity is greatly improved, and since there is no need for Grooves are provided on the body, so the thickness of the body can be set relatively thin and the weight is light.
The entire subframe structure is exactly the same as the entire rear electric drive axle previously exposed, but this time the angle is corrected, and it can be clearly seen that the entire rear suspension structure is completely consistent with the actual vehicle.
Comparing the patent application drawings and spy photos of the rear suspension of the actual car, we can clearly see that they are exactly the same. The structure of the subframe, especially the link position with the lower swing arm, is exactly the same. It can be confirmed that this utility model The application catalog is to lay the theoretical foundation for the plug-in hybrid version of T1D.
In addition, it can be said that the name of T1D in the catalog declaration information is still Tiggo 8, but there are also Tiggo 8 with current sales reported in the same period, mainly 1.5T+48V system, if The relationship between the two is to directly replace the model, which is interesting. It is a bit difficult to understand the micro-hybrid data at the same time. Therefore, it is initially judged that the real intention is to make a Tiggo 8 model series, that is, the final launch name of T1D is still in the ice. Status, now is just the first step of declaration. It is possible to add a suffix name before it is launched, such as the possibility of naming the Tiggo 8 Pro version. As for the plug-in hybrid version, it will be next year at the earliest. It involves more than just plug-in. The hybrid itself is an electric four-wheel drive system after all. The entire suspension system has almost completely changed its structure, so the desired test will naturally be extended. The previously mentioned distributed drive system (that is, the wheel hub motor) developed based on the Tiggo 8 platform ) has also started bidding. Of course, this does not belong to the category of T1D PHEV version. It can only be said that the Tiggo 8 platform is highly valued.
