DEVELOPMENT AND ENHANCEMENT OF A SMART AND ACTIVE FOUR-WHEEL SUSPENSION SYSTEM

Abstract This innovation is about designing, creating, assessing and evaluating an adjustable suspension device for a vehicle. This system is designed to improve car performance from rough to flat surfaces in all field conditions. A adjustment to the double-triangle four-bar connecting suspension completes the proposed design. The changes allow the upper links of the suspension system, in order to meet operator's requirements, to adjust vertical location on the fly. The change of location changes the suspension geometry of the vehicle; in particular the anti-squatter that affects the slope of the vehicle and consequently traction. Traction is also directly regulated by the suspension system modification. We have extensively tested the effects of the adjustable suspension system through film motion analysis of a prototype vehicle before and after the proposed design amendments. Future implementations of this design should boost cars of all sizes, from mobile robots to vehicles. The results will be obtained. The benefit of our design is the on-the-fly adaptability in addition to scalability, allowing adaptations to the suspension output of the pitch or obstacle to be made. Sensor --...-.
