The function of 1. watt connecting rod: balance the centrifugal force on the wheels on both sides, reduce the centrifugal force generated by the lateral force when turning, and keep the wheels on both sides in the most suitable contact with the road surface to achieve the best adhesion. On the one hand, the driving comfort of the vehicle is improved, and at the same time, the vehicle tracking is strengthened.
2. Multi-link (multi-link independent suspension) function: The main control arm can adjust the toe-in of the rear wheel, improve the driving stability of the vehicle and effectively reduce tire friction.
Second, the overview of the two is different:
Overview of Watt connecting rod: Watt connecting rod was originally invented by legendary British inventor and engineer james watt. Buick Lang Wei adopted this structure on the torsion beam suspension to reduce the influence of the lateral force of the rear wheel on the toe-in.
2. Overview of multi-link: Multi-link independent suspension is composed of connecting rod, shock absorber and damping spring. It has more connecting rods than ordinary suspension. Traditionally, a suspension with four or more links is called a multi-link suspension.
Third, the principles of the two are different:
1, Watt connecting rod principle: When the car turns, centrifugal force will act on the wheels. The function of Watt connecting rod is to balance these centrifugal forces on two wheels, and to reverse these forces to the other side. In this way, the wheels on both sides can always keep the most suitable contact with the road surface, and the car can become more flexible when turning. After equipped with Watt connecting rod, from the actual control effect, it is no less than the rear axle model equipped with ordinary independent suspension.
2. Multi-link principle: Multi-link suspension can not only ensure a certain degree of comfort, but also make the wheels as vertical as possible to the ground and minimize the inclination of the car body.
Keep the adhesion between the tire and the ground as much as possible. Its handling performance is no different from that of double wishbone suspension. Because of the abundant space and the emphasis on comfort and handling stability, most luxury cars adopt multi-link suspension, which can be said to be an excellent partner for luxury cars.
