Recoil spring mechanisms are useful, for example, in relieving excessive tension in the track of track-type vehicles. Because the idler wheels recoil in a one-to-one relationship against a recoil spring, the tension in the track still increases drastically from when recoil first starts to full recoil. The subject variable leverage recoil mechanism has the idler wheel mounting bracket and first and second links arranged such that equal increments of movement of the idler wheel from a normal operating position toward a recoiled position results in progress...
A recoil mechanism for resiliently resisting recoil movement of an idler wheel of a track belt mechanism having a track belt entrained around the idler wheel and a drive wheel comprising: a frame; an elongate recoil spring mechanism having first and second end portions, said first end portion being connected to the frame; an idler wheel mounting bracket having first and second end portions and an intermediate portion therebetween, said idler wheel being rotatably mounted to the intermediate portion, said first end portion being pivotally connected to the...
