Abstract

The present invention provides a two-stage stiffness type elastomer combined device, including at least one small-stiffness elastic element and a large-stiffness elastic element, wherein the small-stiffness elastic element is arranged in an elastomer pre-compression device and is serially arranged with the large-stiffness elastic element under the action of a pre-compression load F1. The device has combined stiffness being hard at first and then becoming soft and is used as an elastic axle box suspension device of a railway vehicle, effectively solving the contradiction that a linear snaking critical operation speed of the vehicle and curve passing performance of the vehicle cannot be compromised. The device can also be applied to a variety of occasions requiring combined stiffness being soft at first and then becoming hard of an elastomer damping device between related members of the railway vehicle, so as to buffer the wheel rail impact of the vehicle, improve the dynamic performance of the vehicle and guarantee the operation safety of the vehicle to perfect the operation quality of the railway vehicle.
