Abstract
A suspension system is provided for a movable, supported vehicle axle. The suspension system includes a pair of hydraulic suspension cylinders, which are placed between the vehicle axle and a supporting vehicle structure. Each hydraulic suspension cylinder includes a first work chamber connected to a first pressure accumulator, and a second work chamber connected to a second pressure accumulator. A pressure-limiting valve is exposed to pressure in the first work chamber and has an outlet connected to the second pressure accumulator.
Claims5
A suspension system for a movable, supported vehicle axle, having a hydraulic suspension cylinder connected between the axle and a supporting vehicle structure, wherein the hydraulic suspension cylinder includes a first work chamber connected to a first pressure accumulator, and a second work chamber connected to a second pressure accumulator, wherein:
- a pressure-limiting valve is exposed to pressure in the first work chamber and is connected on an outlet side to the second pressure accumulator by a pressure relief line, wherein excess pressure flows from the outlet side of the pressure-limiting valve to the second pressure accumulator in order to protect the hydraulic suspension cylinder from travel-caused excess pressure peaks.
