Inventor is had 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 automobile exhaust
Pipe.After waste gas is entered, backblast inner tube, as inner tube can be moved radially relative to holding tank or is rotated, therefore inner tube
Motion can absorb most of impact that waste gas is produced, reduce vibrations.Elastic ring is for making holding tank after impulsive force disappears
Return.Meanwhile, by flexible silencing cotton, further enter row buffering to the motion of inner tube, and absorb noise, 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 by oil filling hole into holding tank, is delayed the abrasion of bearing,
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 is entered, backblast inner tube, as inner tube can be moved radially relative to holding tank or is rotated, because
The motion of this inner tube can absorb most of impact that waste gas is produced, and reduces vibrations.Elastic ring is for making after impulsive force disappears
Holding tank return.Meanwhile, by flexible silencing cotton, further enter row buffering to the motion of inner tube, and absorb noise, so as to larger
Degree improves noise reduction.
2. major diameter passage and smaller diameter passage are alternately arranged 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 increased
Anti-acoustic capability.
3. oil filling hole is set, lubricating oil is filled by oil filling hole into holding tank, is delayed the mill of bearing
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.
