Abstract
A suspension system for suspending an endless track beneath a tracked vehicle chassis. The suspension system can be a fully coupled suspension, a partially coupled suspension or a non-coupled suspension. The suspension system includes at least one elongated suspension rail having a front portion, a rear portion and a bottom track-engaging portion. At least one suspension arm has an upper end adapted for pivotal connection to the vehicle chassis and a lower end pivotally connected to the suspension rail. The lower end of the suspension arm can optionally have a displacement with a non-linear component. A biasing mechanism provides a biasing force to bias the suspension rail away from the vehicle chassis. The track tensioning system coupled to the suspension arm applies a tensioning force to the endless track in response to displacement of the suspension arm. The tensioning force generates a supplemental force transmitted by the endless track that augments the biasing force of the biasing mechanism. In a suspension system with front and rear suspension arms, the track tensioning system can be coupled to the front or rear suspension arms.
