Development of a Multi-Link Beam Rear Suspension for Front-Wheel-Drive Cars 950585
Research into stability at high speed shows that rear suspension characteristics play an important role in vehicle control and stability. In order to improve the cornering limit steering performance and traction of front-wheel-drive vehicles, where the front wheels bear a large proportion of the load and transmit the driving force, and to maintain vehicle stability when decelerating while cornering, rear suspension characteristics are needed that will fully draw out the cornering force capacity of the rear tires. This requirement continues to grow every year, along with demands for higher levels of comfort in passenger cars, including improved ride quality and quietness.
It was against this background that the new multi-link beam rear suspension, which is installed in the new Maxima and Sentra models, was developed. This paper describes the aims, construction, characteristics and effects of this new suspension, with focus on vehicle control and stability.
