We have developed a new multi-link rear suspension that has a simple link configuration and a lower link that features a connecting bushing mechanism developed by Nissan. This innovative new connecting bushing mechanism not only helps to provide better handling stability by ensuring high stiffness and an adequate level of compliance steer, but also helps to improve the ride comfort by suitably controlling the behavior of tires when they encounter irregularities in the road surface, thereby providing a safe and comfortable driving experience suitable for a high-performance passenger vehicle. The new link layout enabled us to reduce the number of components compared with current multi-link suspensions, we have also achieved weight reductions by precisely controlling the load transmitted to links and suspension members.

Development of a New Multi-link Rear Suspension

The requirements of suspension systems have become increasingly complex in recent years due to the expansion of global markets and diversification of the conditions under which vehicles are used in different parts of the world. It is also becoming increasingly important to ensure that vehicles offer the secure handling stability which are expected by drivers, but can also provide an adequate level of ride comfort when driving on a wide diversity of road surfaces in all parts of the world. From an environmental viewpoint, it is also essential to achieve weight reductions for better fuel economy.To meet these wide-ranging requirements, we have developed a new multi-link rear suspension that has a simple link configuration and a lower link that features a connecting bushing mechanism developed by Nissan. This innovative new connecting bushing mechanism not only helps to provide better handling stability by ensuring high stiffness and an adequate level of compliance steer, but also helps to improve the ride comfort by suitably controlling the behavior of tires when they encounter irregularities in the road surface,…

Development of new multi-link front suspension for FF vehicle

Nissan Co., Ltd.-Junso Ichiba, Atsuo Tanaka, Yoshihiro Kawabe, Hiroshi Mimura
  • Technical Paper
  • 2001-08-0080
Published 2001-05-23 by Society of Automotive Engineers of Japan in Japan
We developed a new multi-link front suspension for the following purposes: to enable the same platform to be shared with other strut suspension vehicles, to improve NVH performance substantially and to increase the potential for ride and handling performance. This new multi-link suspension has an all-new structure consisting of struts and upper links that are optimally arranged. The major features of this new suspension include the following mechanisms: a lower placed upper link with a ball joint mounted to the suspension member, a third link and a strut bottom bracket with a new design and a member insulator with a new structure.

Development of new multi-link front suspension for FR vehicle

The new multi-link front suspension for rear-wheel-drive vehicles combines superb handling and stability with a comfortable ride. Handling, stability and ride comfort are improved by optimizing the link layout, which separates the two lower links and a long upper link without protruding into the engine compartment. A shorter engine compartment and front overhang are achieved by reducing the longitudinal movement of the tires. The suspension weight is reduced by using aluminum for all links and knuckle-arms and by rationalizing their shapes.
