What is the difference between double wishbone and multi-link?
2 Answers
The differences between double wishbone and multi-link: 1. Different structures: The double wishbone type adds an additional wishbone to the MacPherson suspension; the multi-link independent suspension consists of links, shock absorbers, and damping springs. 2. Different functional characteristics: The double wishbone type has high lateral rigidity, excellent anti-roll performance, good grip, and clear road feel; the multi-link type allows the wheels to remain as vertical as possible to the ground, minimizing body tilt. 3. Different application models: Models using the double wishbone type include the FAW Toyota Crown and FAW Toyota Reiz, as well as Audi's luxury SUV Q7 and Volkswagen Touareg; models using the multi-link type include the Beijing Benz-DaimlerChrysler E-Class, FAW-Volkswagen Audi A4L and A6L, etc.
I always enjoy studying car suspension systems. The main difference between double-wishbone and multi-link suspensions lies in their design. The double-wishbone uses two fork-like arm structures, with one end fixed to the car body and the other connected to the wheel. It controls the vertical movement of the tire, making the wheel more stable during turns with less body roll, offering more precise handling—making it suitable for front suspensions and sports cars. The multi-link system, on the other hand, consists of multiple link combinations, with each small link working independently to manage the tire's up, down, left, and right movements, absorbing road vibrations more smoothly for better comfort. It's commonly used in rear suspensions or luxury vehicles. Structural differences lead to performance variations: double-wishbone responds quickly but takes up less space; multi-link offers better cushioning but is more complex, potentially making manufacturing and repairs more expensive. Modern cars often combine both—for example, using double-wishbone at the front to enhance handling and multi-link at the rear to optimize comfort. When choosing a car, pick based on your driving preferences.
