Abstract
A suspension system for a tracked vehicle includes a track roller configured to contact and roll relative to an inner surface of a track. In some examples, the track roller includes an axle member, a roller mounting bracket mechanically connected to the axle member, a frame mounting bracket configured to attach to a frame of the tracked vehicle, and a plurality of coil springs disposed between the roller mounting bracket and the frame mounting bracket. The plurality of coil springs is configured to reduce an impact force transferred from the track roller to the frame of the tracked vehicle.
