| 摘要 |
The disclosure herein describes a muffler assembly consisting of a cover for completely enclosing the muffler of a snowmobile-like vehicle over an aperture provided through the frame of the vehicle. The cover provides a heat barrier between the muffler and the other surrounding components located under the hood of the vehicle while the frame aperture allows air and snow circulation around the muffler inside the cover. To cut down on the intensification of vibration, in a first alternative, the muffler cover and the frame are separated from one another by vibration attenuating means. In another alternative, the muffler cover is fixed directly on the frame and the vibration attenuating means are disposed between the muffler and the cover.
