ABSTRACT:
A shock-absorbing device, suitable for use with an idler for a crawler belt, contains a spring box (10) having a flange (12) secured at one end and a bracket (13) secured at the other end, with an annular partition wall (11) extending radially inwardly from a central portion of the wall of the bore of the spring box (10) to form a first spring chamber (16) and a second spring chamber (17) spaced apart along the length of the spring box (10). A first spring (23) and a first spring pushing member (20) are installed in the first spring chamber (16), and a second spring (33) and a second spring pushing member (30) are installed in the second spring chamber (17). An external force F, applied to an idler (3) and a guide bar (18), is propagated through the first holder (21) of the first spring pushing member (20) to the first spring (23), and then, after the first spring (23) has been compressed a predetermined amount, through the first elongated member (26) to the second holder (31) of the second spring pushing member (30) to compress the second spring (33). The load of the device is the load of only the first spring (23) until the first spring (23) has been compressed the predetermined amount and then the load is the sum of the loads of the first and second springs (23, 33).
