BACKGROUND

Technical Field

Related Art

At present, shock absorbers of ordinary roller cage shoes use springs as shock-absorbing and bearing parts, the stiffness coefficient of the springs is a fixed value, the shock-absorbing effect generated by the springs changes linearly, and as a result, the shock-absorbing effect of the springs is unsatisfactory when the springs bear great transverse vibration. Wire rope shock absorbers used by the present invention can effectively solve this problem, the stiffness coefficient of the wire rope shock absorbers is a non-fixed value, the stiffness coefficient can increase as transverse vibration increases, and therefore the shock-absorbing effect of the wire rope shock absorbers is better than that of the existing ordinary roller cage shoes when the wire rope shock absorbers bear great transverse vibration.
