Abstract
The invention discloses a kind of EGR connecting pipe component of motor, comprising: the first bellows segment, its one end is connected with the EGR valve of motor by the first adpting flange; Second bellows segment, its one end is connected with the cooler for recycled exhaust gas of motor by the second adpting flange, is straight length between the other end of the second bellows segment and the other end of the first bellows segment; And modular support, it is used for fixing straight length position.The bellows of this EGR connecting pipe component is divided into two sections, and centre is straight length, and decoupling is good, by the mounting type that modular support flexibility is fixing and two ends are fixing of centre, plays regulating error, reduces the effect of vibrations, effectively avoid EGR connecting tube to break.
Description
Technical field
The present invention relates to motor, particularly a kind of EGR connecting pipe component of motor.
Background technique
In the egr system of available engine, EGR connecting tube one end is connected in EGR valve, one end is connected on cooler for recycled exhaust gas, general EGR connecting tube is the overall pipe fitting that 0.8mm is thick, because EGR connecting tube two ends connect different component, installation dimension is difficult to control, can cause after installation producing vibration, and it is distant between EGR valve and cooler for recycled exhaust gas, the bellows segment of existing EGR connecting tube is thicker, ripple number is few, thus make bellows harder, decoupling is poor, do not have the effect eliminating alignment error, so, in the working procedure of motor, above-mentioned cooler vibration fierceness is also delivered on connecting tube, connecting tube is easily caused to vibrate fierce, thus break.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of EGR connecting pipe component of motor, by changing form and the composite design cribbing of connecting tube, making the decoupling of EGR connecting tube good, effectively reducing the vibrations of connecting tube, avoiding EGR connecting tube to break.
For achieving the above object, the invention provides a kind of EGR connecting pipe component of motor, comprising: the first bellows segment, its one end is connected with the EGR valve of motor by the first adpting flange; Second bellows segment, its one end is connected with the cooler for recycled exhaust gas of motor by the second adpting flange, is straight length between the other end of the second bellows segment and the other end of the first bellows segment; And modular support, it is used for fixing straight length position.
Preferably, modular support comprises semicircular plate and straight plate, the front end, circular arc position of semicircular plate is provided with projection, the position, top of straight plate is provided with groove, the circular arc position of semicircular plate is fastened on the side of straight length, straight plate keeps off the opposite side at straight length and groove snaps in projection, together with semicircular plate is bolted on the lower end of straight plate.
Preferably, the bottom part of straight plate is provided with bolt hole and is used for modular support to be fixed on the body of motor.
Preferably, the wall thickness of the first bellows segment and the second bellows segment is all 4mm.
Preferably, the spacing between the ripple of the first bellows segment and the second bellows segment is 4mm.
Compared with prior art, the present invention has following beneficial effect: the bellows of this EGR connecting pipe component is divided into two sections, centre is straight length, decoupling is good, by the mounting type that modular support flexibility is fixing and two ends are fixing of centre, play regulating error, reduce the effect of vibrations, effectively avoid EGR connecting tube to break.
