    Abstract:

    BAE Systems Hägglunds AB manufactures military land vehicles, there amongst the shrapnel protected all terrain vehicle (BVS 10) which this report deals with. The BVS 10 is a twin-cab vehicle with articulated steering. Each cab has two tracks and in each track there are twelve wheels. The two rearmost wheels keep the right track tension while the other wheels are mounted to the spring elements via swing axles. The spring elements are rubber torsion bushings mounted in the Skid Beam attached to the chassis. The weight of the BVS 10 has increased from 11 to 16 tons because of increased levels of protection. The increased weight affects the lifespan of the spring elements negatively. The aim of this master thesis is to develop a help spring system for the BVS 10 that is mountable on an existing Skid Beam. After preparation, formulation of a product specification and generation of ideas a couple of concept proposals was presented. The concepts were compared among themselves and against the product specification. After evaluation the leaf spring concept was chosen. The function of the leaf spring is verified by calculations and simulations, also ideas about materials and mounting is presented. The help spring system will increase the stiffness of the spring system of the all terrain vehicle, give a higher ground clearance and relive the rubber torsion bushings.Validerat; 20130612 (global_studentproject_submitter
