  • Patent number: 6619728
    Abstract: A suspension system is for vehicles and its components such as vehicle cabs that at least partially form a load. The components are subject to accelerations in the starting and breaking directions. At least one suspension cylinder can be subject to a load. The fluid chambers of the cylinder are connected to a shock-absorbing device in a fluid conveying manner. The shock-absorbing device counteracts the free movement of the load and throttles the fluid flow linked with it. A sensor device is provided for controlling the shock-absorbing device, and is provided with a control mass that is subject to the accelerations. The sensor device acts upon at least one throttling device in such a way that the fluid flow is increasingly throttled when the acceleration is increasing. The suspension system is improved by the sensor device, next to the user-friendly basic suspension, providing a suspension that is able to guarantee safety even in extreme accelerations and helps to prevent dangerous driving conditions.
