Title:
TWO-STAGE-RIGIDITY COMBINATION ELASTIC-MEMBER DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/101094
Kind Code:
A1
Abstract:
A two-stage-rigidity combination elastic-member device having at least one low-rigidity elastic element (1) and one high-rigidity elastic element (2), the low-rigidity elastic element (1) being disposed in an elastic-member precompression device (3) and, when under the effect of a precompression load F1, being arranged in serial connection with the high-rigidity elastic element (2). The device has a hard-to-soft rigidity combination, allowing said device to be used as an axlebox elastic suspension device on a railway car. The invention solves the problem of cars not being able simultaneously to satisfy both critical speed requirements when snaking along a straight line and curve negotiation performance requirements. The invention can also be applied in various settings in which elastic-member shock-absorbing devices having a hard-to-soft rigidity combination are required between components of a railway car to lessen the car's wheel-rail impact, raise the car's dynamic capacity, safeguard the car's operating safety, thereby improving the service quality of the car.
