Utility model content
Technical problem to be solved in the utility model be to provide a kind of survivable, structure is firm and good damping effect Exhaust manifold.
For solving above-mentioned technical problem, exhaust manifold of the present utility model, including the first flange being sequentially connected with, first straight Pipe, the first corrugated tube, the second straight tube and the second flange;For welding between first corrugated tube and the first straight tube, the second straight tube;Described Exhaust manifold also includes the second corrugated tube;Described second corrugated tube and the first bellows structure is identical, matching form;Second ripple Pipe box is outside the first corrugated tube;The two ends of the second corrugated tube are welded with the outer surface of the first straight tube, the outer surface of the second straight tube respectively Connect.
After using above structure, this utility model has the advantage that
1. using double-ply bellows structure due to exhaust manifold, the i.e. second bellows-sheathed is outside the first corrugated tube.So, exist During use, can mutually support under the effect that corrugated tube is given a shock and make its structure firm;Reduce that corrugated tube destroyed can Can property.
2., in the case of corrugated tube is given a shock, the second corrugated tube and the first corrugated tube are respectively provided with the effect of damping, from And the function to exhaust manifold integral shock-absorbing can be played during motor racing.
Preferably, between inner surface and the outer surface of the first corrugated tube of described second corrugated tube, there is interval.So, exist During motor racing, interval can be supplied to the second corrugated tube and the respective oscillation space of the first corrugated tube, it is to avoid the second ripple Stricture of vagina pipe and the superposition of the first ripple tube vibration, thus further function as the function to exhaust manifold integral shock-absorbing.
Preferably, it is provided with elastic layer between inner surface and the outer surface of the first corrugated tube of described second corrugated tube.So, During motor racing, elastic layer can play the effect of further damping, thus further functions as exhaust manifold overall The function of damping.
Preferably, the thickness of the first corrugated tube is 2-3mm;The thickness of described second corrugated tube is 2-3mm.So, this First corrugated tube of thickness and the second corrugated tube not only have good pliability, temperature tolerance, resistance to pressure;Also have and preferably subtract Pinking, thus further function as the function to exhaust manifold integral shock-absorbing.
Preferably, the first corrugated tube is being provided with tilting section with the first straight tube junction;The end of the first straight tube is inclined plane; First straight tube is inserted in the first corrugated tube, and inclined plane pushes against with the inner surface of tilting section.So, it is inserted in first due to the first straight tube In corrugated tube, the first corrugated tube is played the effect of support by the first straight tube, improves the structural strength of the first corrugated tube, reduces ripple Stricture of vagina pipe receives the probability of destruction;And inclined plane pushes against with the inner surface of tilting section, the first corrugated tube and the first straight tube, Play spacing effect during two straight tube weldings, improve production efficiency.
Preferably, the first corrugated tube and the first straight tube are provided with the interface arrangment cooperated in junction;Described card access node Structure includes protruding from bulge loop that the first straight tube outer surface arranges and is located on the first corrugated tube and recessed with bulge loop corresponding position Circle;Bulge loop is connected in recessed circle.So, bulge loop and recessed circle clamping, on the one hand play spacing effect, on the other hand play reinforcement The effect of the structural strength of the first corrugated tube and the first straight tube junction.
Preferably, the first corrugated tube and the first straight tube are provided with the sealing structure cooperated in junction;Described sealing is tied Structure includes the groove arranged around the first straight tube outer surface;Sealing ring it is provided with in groove;One end of sealing ring and groove inner surface Laminating, the other end of sealing ring and the inner surface laminating of the first corrugated tube.So, the effect of reinforcement sealing further is played.
