Dubrovskiy, A., Aliukov, S., Rozhdestvenskiy, Y., Dubrovskaya, O. et al., "An Adaptive Suspension of Vehicles with New Principle of Action," SAE Technical Paper 2014-01-2310, 2014, doi:10.4271/2014-01-2310.
We have developed a fundamentally new design of adaptive suspension systems of vehicles. Their technical characteristics and functional abilities are far better than the existing designs of suspensions. We have developed the following main suspension components of vehicles: a lockable adaptive shock absorber with an ultra-wide range of control performance, implementing “lockout” mode by means of blocking adaptive shock absorber, and an elastic element with progressive non-linear characteristic and automatic optimization of localization of work areas. Our patents confirm the novelty and efficiency of our major design decisions.Advantages of our developments in the vehicle suspensions are the following. Firstly, it should be noted that when the vehicle is in a wide range of speeds in a so-called “comfort zone”, we were able, by applying the non-linear elastic element, to reduce significantly the stiffness of the elastic suspension elements in compare with the regular structures - at least in two times. Dynamic loads on the crew, passengers, equipment, components and assemblies of the vehicles are reduced in a great extent. Secondly, the stiffness of the non-linear elastic element beyond “comfort zone” is increasing dramatically: first - more than three times in comparison with regular elastic elements; and further increasing of the stiffness of the elastic elements is more than 60 times.In case of usage of the developed designs of the lockable adaptive shock absorbers and the nonlinear elastic elements, the vehicles will be equipped with the suspensions, whose techno-economic indicators surpass in a qualitative sense the world-famous counterparts.
