What is a Double Wishbone Suspension?
2 Answers
Double wishbone suspension is also known as double A-arm suspension or double swing-arm suspension, and it is a type of double transverse arm suspension. The double wishbone suspension consists of upper and lower wishbones, with both wishbones absorbing lateral forces, while the strut only bears the weight of the vehicle body, resulting in high lateral stiffness. Below is a related introduction: 1. Composition: The double wishbone suspension is composed of two A-arms of unequal lengths and a shock absorber acting as a strut. The upper and lower A-arms are connected to the upper and lower arms of the steering knuckle on the wheel via ball joints, respectively, while the connected shock absorber and coil spring act as the strut and kingpin. Its upper end is connected to the subframe, and the lower end is connected to the lower control arm. 2. Transverse arm suspension: This refers to an independent suspension where the wheels swing within the transverse plane of the vehicle. The double transverse arm suspension refers to a suspension system with two transverse arms. Double transverse arm suspensions are further divided into equal-length and unequal-length double transverse arm suspensions. The equal-length double transverse arm suspension can maintain the main inclination angle unchanged when the wheels move up and down.
As a seasoned driver with years of experience, I find double-wishbone suspension quite practical. Simply put, each wheel is equipped with two fork-like arms that move independently without interfering with each other. This makes the car more stable, especially when cornering or driving at high speeds, as the body roll is significantly reduced, and the handling response is exceptionally sharp. I've tested many car models, and those with double-wishbone suspension have less vibration on rough roads, offering great comfort without making you feel dizzy. Compared to the common MacPherson strut, it's more durable and safer. Although maintenance might cost a bit more, it's worth it in the long run. If ordinary family cars or SUVs use this, taking your family out will definitely be safe and worry-free.
