SHOCK ABSORBER FOR CRAWLER

摘要

A shock absorber for a crawler is disclosed. The shock absorber may have a coil spring to bias an idler wheel from a frame of the crawler. The shock absorber may also have an adjustment cylinder to adjust a bias force of the coil spring. The adjustment cylinder may have a flange projecting radially outward. The shock absorber may have a support member disposed circumferentially around at least a portion of the adjustment cylinder. The support member may have a spring bearing portion projecting radially outward. The shock absorber may have a retaining plate projecting radially from the adjustment cylinder. The retaining plate may be configured to prevent axial separation of the adjustment cylinder and the support member. The coil spring may be positioned on an outer peripheral side of the adjustment cylinder and the support member and disposed in abutting contact with the flange and the spring bearing portion.
