To provide a suspension system for vehicles such as a forklift capable of moving a steering axle 20 like an articulate in the lateral direction over a contact location of an articulation stopper.

When movements of the steering axle 20 is within a first range of articulation, the steering axle 20 is coupled to a vehicle flame 24 so that the axle pivots about a first location 25 with respect to the vehicle flame 24. When the movements of the steering axle 20 is within a second range of articulation greater than the first range of articulation, the steering axle 20 pivots about a second location 27 with respect to the vehicle flame 24. The second location 27 exists in the lateral direction outer side of the location 25. When the movements of the steering axle 20 exceeds the second range of articulation, the suspension system retains the steering axle 20 in substnatially rigid contact with the vehicle flame 24.
