Inventor has found through research, although the fixed structure of increase can make exhaustor fix more firm,
Waste gas can be transferred to the chassis of automobile to the impulsive force of aerofluxuss inside pipe wall when by exhaustor by fixed structure, so as to increase
The overall vibrations of automobile, cause the noise reduction cannot to be obviously improved.For this purpose, inventor providing a kind of silencing exhaust pipe
Road.After waste gas is entered, backblast inner tube, because inner tube can be moved radially relative to holding tank or be rotated, therefore inner tube
Motion can absorb most of impact that waste gas is produced, reduce vibrations.Meanwhile, by flexible silencing cotton, further to inner tube
Motion enter row buffering, and noise is absorbed, so as to largely improve noise reduction.
Further, possess the major diameter passage and smaller diameter passage being alternately arranged in said inner tube.
Be alternately arranged major diameter passage and smaller diameter passage in inner tube, waste gas during by inner tube, big straight
Spread in the passage of footpath, compressed in smaller diameter passage, so that the sound wave in waste gas is cleared up, further increase drop
Make an uproar performance.
Further, the inner surface setting in said inner tube has porous sound absorbing cotton layer.
There is porous sound absorbing cotton layer in the inner surface setting of inner tube, enter one and improve anti-acoustic capability.
Further, the oil filling hole connected with the holding tank two ends is offered on the outer tube；Also include
The plug coordinated with the oil filling hole.
Oil filling hole is set, lubricating oil is filled into holding tank by oil filling hole, delay the abrasion of ball,
Improve service life of the present utility model.
Further, also including corrugated tube, one end of the corrugated tube is connected with the inner surface of the outer tube, the ripple
The other end of pipe is connected with the inner surface of said inner tube；The ripple duct occlusion said inner tube end and the holding tank end it
Between gap.
Corrugated tube is set, prevents the lubricating oil for filling from entering in inner tube, so as to improve safety of the present utility model.
This utility model has the advantages that：
1. after waste gas entrance, backblast inner tube, because inner tube can be moved radially relative to holding tank or be rotated, because
The motion of this inner tube can absorb most of impact that waste gas is produced, and reduces vibrations.Meanwhile, by flexible silencing cotton, further
Row buffering is entered in motion to inner tube, and absorbs noise, so as to largely improve noise reduction.
2. be alternately arranged major diameter passage and smaller diameter passage in inner tube, waste gas during by inner tube, big
Spread in diameter channels, compressed in smaller diameter passage, so that the sound wave in waste gas is cleared up, further increase
Anti-acoustic capability.
3. oil filling hole is set, lubricating oil is filled into holding tank by oil filling hole, delay the mill of ball
Damage, improve service life of the present utility model.
4. corrugated tube is set, prevents the lubricating oil for filling from entering in inner tube, so as to improve safety of the present utility model.
