A drive chain comprises a plurality of inner links (1) interconnected by intermediate outer links and elongate pins (7) that are received in apertures in the inner and outer links. There is substantial clearance between the outer link and the corresponding inner links so as to permit flexion of the adjacent elongate pins in a direction substantially parallel to the length of the chain. The outer link may be in the form of a separate plate (6) or may be an integral part of the pins. In one embodiment the outer link is a crimped plate that offers resilience in the direction of the chain. The drive chains provide for shock absorption. |
