  • X-spring device for a motor vehicle wheel suspension
    Patent number: 11358426
    Abstract: An X-shaped spring device for a transportation vehicle wheel suspension having for each wheel side a first leaf spring and a second leaf spring made of fiber-reinforced plastics material and arranged one above the other. The first leaf spring is supported at the wheel side with one end and the second leaf spring is supported at the vehicle structure side with one end, and a first securing device on which the first leaf spring and the second leaf spring are joined and clamped, and which has a bearing for pivotable bearing at the vehicle structure side. The first securing devices of both wheel sides are connected to each other to provide a stabilizer action by using a spring.
