Delta platform was born in 2003 and was developed by General Motors North America R&D Center. The original intention of research and development is to face the North American market. Later, with the popularity of Opel Astra, GM began to look to the 3300 sedan platform.
Finally, based on the characteristics of 3300 automobile platform and Delta platform, the current global Delta platform is deduced. This platform is similar to Volkswagen P Q3 5, which is limited to A-class cars.
Flexible wheelbase
The D2XX platform covers many models. In addition to the variable wheelbase, the change of suspension structure can also be realized through this platform.
light weight
General Motors is a forward-looking automobile company. In recent years, the new models have made a big fuss about lightweight, and the biggest highlight of D2XX is lightweight.
Support more advanced configuration blessing
The design of the platform takes this into account, which also enables different models on the platform to be equipped with more advanced configurations.
Overview of Buick Lang Wei Chassis
Layout: pre-precursor
Front suspension: McPherson independent suspension
Rear suspension: rear torsion bar beam+Watt connecting rod dependent suspension.
Lang Wei's front suspension is McPherson-style independent suspension, which is difficult to adjust, but also tough, and can still easily cope with big bumps.
The rear suspension is based on Watt connecting rod torsion beam suspension, which is very common in general compact cars. The advantage of this suspension is that when the vehicle turns, the centrifugal force will better balance the wheels on both sides through the Watt connecting rod, so that the inner wheels can get better ground adhesion.
This suspension structure is also a highlight of Lang Wei's handling. The torsion beam rear suspension with Watt connecting rod will be more stable in handling.
General situation of Buick Lang Wei anti-collision beam
Front collision beam
Lang Wei's front bumper is removed, and its bumper beam can be seen. It is an aluminum alloy bumper beam covering about 64% of the front of the car, with a thickness of 2.54 mm In the case of small-area collision, the protection of the bumper beam to the suspension is a bit insufficient.
Rear impact beam
Lang Wei's rear bumper is also a dazzling white aluminum alloy anti-collision beam, which belongs to conscience and is very rare in its class. For cost reasons, general car companies will choose stamped steel plates as anti-collision beams instead of aluminum alloys.
