The so-called double wishbone independent suspension is an independent suspension in which the two wishbones swing in the transverse plane of the car. Generally, there are two suspensions of equal length and unequal length. The kingpin can be maintained when the wheels are jumping up and down. The inclination angle remains the same, but due to excessive changes in the wheelbase, it is easy to cause tire wear.
The so-called multi-link suspension refers to three or more link rods. At present, there are mainly four-link and five-link suspensions, which can provide control in multiple directions, so that the tires can maintain a more reliable driving track and drive more comfortably.
1. In terms of dynamic performance: Because the double wishbone independent suspension is generally composed of two rocker arms of unequal length, they can absorb the lateral force together, and through a certain reasonable configuration, the wheelbase and the front wheel can be carried out within a certain range Change to achieve the corresponding power, the overall power performance is better, generally used in sports car racing; and the multi-link is mainly used to accurately control the angle of contact between the wheel and the ground, and mainly about the adjustment of the steering angle, so the overall power The performance is far inferior to the double wishbone independent suspension.
2. In comfort performance: Because the double wishbone independent suspension is mainly used in a variety of road conditions, the adaptability of the road is relatively good, so the general comfort is not high, and the multi-link is based on the double wishbone through certain constraints So that the tire has a certain change when it moves up and down, so it has better adaptability, and it can also overcome a certain understeer, and the overall comfort is better.
3. In terms of cost: Because the structure of the double wishbone independent suspension is more complicated, it also occupies a lot of space and the manufacturing process is also more complicated, so the overall cost is higher; but for multi-links, the same is required. More space, but the manufactured structure is more complex to achieve more performance, so the cost is higher.
