let's take a closer look at the mystery of the front suspension. It can be clearly seen from the figure that the lower front and lower rear control arms form a double wishbone structure, and the steering rod at the front end of the tire centerline forms a multi-link structure. Multi-point stability ensures the steering accuracy of the front wheel, and the righting force can be adjusted more finely. Another advantage of this design is that the load of the front transmission shaft can be reduced as much as possible, so that the wheel frame can effectively disperse the vibration and impact transmitted by the wheel.
looking at the front suspension from another angle, we can see that the arm on the front suspension is very strong, which is the main load-bearing arm of the front suspension, and the upper fixed point is divided into two parts around the pneumatic shock-absorbing system. It can be seen that BMW has applied a large number of lightweight aluminum alloy materials in the process and made a lightening design, and the multi-arm and multi-node connection can effectively disperse the force on the wheels. With the all-aluminum subframe, the new generation BMW X5 with a load-bearing body can bear the working intensity during off-road in this generation. The anti-roll bar is a special-shaped anti-roll bar, and it is connected with the upper arm by a flexible turning point and a longitudinal arm connecting rod. Judging from this thick anti-roll bar, the brand-new BMW X5 still has good road performance, and the flexible connecting mechanism is added to allow the suspension to have more expansion and contraction space and the body twisting range when off-road.
let's take a look at the rear suspension, which is also the technical highlight of this new X5. Let's take a general view of the rear suspension first. How to look fiercely to see if there is an X-shaped feeling? (is this the real meaning of xDrive? Haha, just kidding), in fact, the feeling of this X shape comes from the illusion caused by the shape of two torsion-resistant reinforcing rods and the exhaust tail section, but this design has a reason, which will be introduced later. You can also clearly see the four fixed points of the all-aluminum subframe and the main arm body with five-link independent suspension (with anti-scratch guard plate, it also has certain turbulence and diversion effects). Of course, there is the domineering tire with a width of 315. Seriously, if this tire is punctured during cross-country, it is more difficult to repair this tire than to find a charging station in the wilderness (fortunately, it is a flat tire).
that's what I brought you about "BMW X5 chassis overview and front suspension". if you think my sharing is useful, please give me a compliment. Thank you. @219
