One of the things noticed when a snowmobile is powered by a near-silent electric motor is how much noise the machine still makes. The source? Track noise. Our staff even noticed this with the new ACE 900 models from Ski-Doo, in that the engine’s intake and exhaust noise had been reduced so much that you now heard more track noise than anything else.
So it makes perfect sense that track manufacturer Camoplast Solideal (now Camso) has filed a patent application for even quieter track, specifically snowmobile tracks without internal reinforcement rods. In the patent application, data is provided showing significant noise level reductions, up to as much as 15 dB quieter in operation depending on lug design and track speed.
According to the patent application, the “Noiseless Elastomeric Track” is free of transversal reinforcing rods. When the snowmobile is operated at a given speed, less noise is generated than if the track had transversal reinforcing rods embedded in the elastomeric body.
