The purpose of study described in t

The purpose of study described in this paper was to design the whole new suspension. The reason why we can’t use some existing suspension was that we get the unconventional shape of bodywork. Our solution comes out from extended arms, which are attached to frame. On the other end of arm is embedded knuckle, which hold the wheel hub and wheel. During the phase of designing we want to make easy, adjustable and if it’s possible cheap solution. Designing parts was based on many calculations and simulations of strength analysis. Simulations of most critical parts are also published in this paper. First of them is base of suspension, which we want to have rigid, because it is only fixed part, to which are every other part movably assembled. Simulation of this part told us that critical load of 2000 N bends the ends of beams only 2 mm and stresses during this load is in weld area so now we know that we need to strengthen the weld. Second simulation deals with strength analysis of extended arm. On this part causes two loads. First by acting of springs and second depends from weight of vehicle. From simulation comes out that we over dimensioned this part so we make several changes including lightening holes and in this paper is shown the final shape of arm. Realization of this suspension in time of writing of this paper is still far away, because design od suspension is just one from many task that we need to solve before final realization of build this electric lightweight car.
