The front suspension of Lang Wei Buick is called the enhanced McPherson front suspension. This suspension system adopts a shock absorber with elastic spring, which can give better consideration to driving comfort and handling. The rear bushing of the front lower control arm is hydraulic, which can improve the shock absorption ability and isolation ability to uneven road surface compared with rubber bushing. At the same time, the front frame is made of all-aluminum material, which realizes 43% lightweight. Buick Lang Wei adopts front McPherson independent suspension and rear torsion beam independent suspension. It shows that in the market segment of compact and medium-sized cars, elites gather. Not to be outdone, Buick has launched a brand-new Veyron, which is positioned as a high-end compact sports car, and its direct competitors are Volkswagen Sagitar and Ling Du. The new Lang Wei focuses on sports and comfort, and a major feature of its suspension is the use of Opel's patented "Watt connecting rod". Let's take a look at Lang Wei's chassis.
● McPherson suspension at the front of the chassis is believed to be familiar to many people, and the torsion beam plus watt connecting rod solves the common shortcomings of torsion beam suspension, and its maneuverability and comfort are no less than that of independent suspension.
● Since the enhanced McPherson front suspension is positioned as a new generation sports car, Buick Lang Wei's front suspension is naturally not ordinary people. The former McPherson suspension is the "standard" in the market, and Lang Wei has upgraded on this basis.
1. All-aluminum subframe The all-aluminum front subframe reduces the weight, and at the same time, the chassis rigidity is significantly enhanced, which improves the handling performance of the whole vehicle.
2. Details and materials of the front suspension The rear bushing of the front lower control arm is hydraulic. Compared with rubber bushings, it can greatly improve the shock absorption ability and isolation ability to uneven roads, significantly improve the quality of ride comfort, and of course, the cost is higher.
● Opel's patented Watt connecting rod torsion beam is hung behind, and you can see the torsion beam. I believe many people will subconsciously think that this is a device compared with the price drop. But in fact, after in-depth understanding, you will find that the torsion beam rear suspension of this Watt connecting rod is no less than the independent suspension.
The separation of shock absorber and shock absorber spring can effectively increase the lateral space inside the car and make the space inside the car bigger.
In ordinary torsion beam suspension, the rear axle bushing needs to bear both longitudinal force and lateral force, so it often forms a certain angle with the longitudinal axis of the car body to compromise comfort and handling.
Watt connecting rod "liberates" the rear axle bushing, making it only bear longitudinal force, so the bushing can be arranged perpendicular to the longitudinal axis of the car body, which greatly improves the comfort.
● Belt-driven electronic power steering Belt-driven electronic power steering is a direct power steering form to achieve higher power transmission efficiency.
● Power experience ● Road experience Lang Wei's rear suspension adopts the latest generation of Watt connecting rod, which has good performance in cornering and anti-rolling. Lang Wei's chassis has a tough adjustment and a rich sense of road. Although some bad roads will bump, the chassis gives people a thick feeling, and the suspension action is very simple when passing through the uneven road quickly.
Summary: From the product point of view, Lang Wei's rear suspension with torsion beam and Watt connecting rod is a bright spot. The Lang Wei 20T used for test drive shows sufficient confidence compared with competitors in terms of design, interior materials, rich configuration and driving quality. As a new model, whether Lang Wei can open a new world in the future depends on its subsequent market performance. We will wait and see.
