Abstract
The present invention relates to a kind of silencing apparatus (1), it is rigidly secured on the compressor case (2) at first join domain (12,22) by fixed element (3).In second join domain (13,23), the surface of contact of this silencing apparatus rests on the surface of contact of compressor case, wherein owing to the contact at the second join domain place relative with rigidly fixing of first join domain this silencing apparatus is applied prestressing force.Described prestressing force has improved the natural frequency of this silencing apparatus, and can avoid producing on silencing apparatus the excessive vibration stress of not allowing thus.
Description
Technical field
The present invention relates to the exhaust-gas turbocharger field.
The present invention relates to a kind of fixing device of the silencing apparatus on compressor case.
Background technique
In most of the cases, the exhaust-gas turbocharger that is used for supercharging of internal combustion engine has filter and sound damper in compressor inlet.This silencing apparatus that is equipped with filter preferably is rigidly connected by fastening flange and compressor case.This connection is for example by EP 1 186 781 A1, among Fig. 1 as seen.
This exhaust-gas turbocharger or directly or by special base be fixed on the motor suspension.In most of the cases, the axial distance between base and silencing apparatus is very big.By engine luggine, silencing apparatus may be energized and cause the high vibration of not allowing.It is especially true when the natural frequency of silencing apparatus just is higher than the natural frequency of turbosupercharger indistinctively.In this case, the excessive vibration that appearance is not allowed in silencing apparatus.
Summary of the invention
Therefore task of the present invention is, takes measures in the fixing device of the silencing apparatus on compressor case, to prevent the excessive vibration of not allowing of silencing apparatus.
According to the present invention, this task solves by fixing device according to the present invention.
This silencing apparatus is rigidly secured on the compressor case by means of bolt in the contact area of fastening flange.When wherein being installed to silencing apparatus on the compressor case in the axial direction, at first in the contact of region generating between silencing apparatus and compressor case of support flange, in the contact area of fastening flange, there is the gap in the axial direction, described gap only is closed by the and then fastening of bolt, thereby the shell of silencing apparatus is slightly twisted between fastening flange and support flange, and silencing apparatus is loaded with axial prestressing force thus.
By this prestressing force, the natural frequency of silencing apparatus is improved widely.
Other advantage is by drawing in other mode of executions according to the present invention.
Description of drawings
Below schematically illustrated and set forth some forms of implementation in more detail by accompanying drawing according to fixing device of the present invention.In all accompanying drawings, the element with same function is marked by identical reference number.Wherein:
Fig. 1 illustrates the silencing apparatus of exhaust-gas turbocharger and the sectional drawing of compressor case, and they interconnect by means of fastening flange and support flange according to the present invention, and
Fig. 2 a)-k) is illustrated in the enlarged view according to the support flange of Fig. 1 in the different forms of implementation.
Embodiment
Fig. 1 illustrates the sectional drawing with compressor case 2 and air inlet side of the exhaust-gas turbocharger of the silencing apparatus 1 at the air intlet place that is set at compressor.Whole turbine pusher sides of the compressor impeller that can pivotally install and exhaust-gas turbocharger are not illustrated.
This silencing apparatus comprises the matrix of the sound insulationg board 11 that the some quilts of supporting radially are provided with.Air to be compressed according to arrow diametrically by being set at the filter 15 on silencing apparatus ring week and passing the intake grill that is fed to compressor between the sound insulationg board.
This silencing apparatus is fixed on the compressor case by means of bolt 3 or other the suitable fixing device that several distributed along ring week.These bolts not only fixing silencing apparatus in the axial direction but also diametrically aspect compressor case.
For by bolt, silencing apparatus has fastening flange 12 in the radially outer zone of the casing wall 14 of compressor case.This compressor case equally also has corresponding fastening flange 22 in the radially outer zone.
In the inner radial zone of the casing wall of described silencing apparatus, be provided with support flange 13.By this support flange, silencing apparatus by axially support on the corresponding support flange 23 on the compressor case.
According to the present invention, the support flange 13 of silencing apparatus is axially applied prestressing force with respect to fastening flange 12.When being installed to silencing apparatus on the compressor case in the axial direction, at first in the contact of region generating between silencing apparatus and compressor case of support flange 13 and 23.Have the gap in the contact area of fastening flange 12 and 22 in the axial direction, this gap is closed by back to back clamping bolt 3.By the sealing in gap, the shell of silencing apparatus is slightly twisted according to the present invention between fastening flange and support flange, and silencing apparatus is loaded with axial prestressing force thus.
Supporting under prestressing force has influence to the natural frequency of silencing apparatus.Corresponding to one-sided overhang clamped, that its natural frequency improves, when it was additionally supported, the natural frequency that is fixed on the silencing apparatus on the compressor case according to the present invention improved.In this way, the natural frequency of silencing apparatus is compared with fixing in a conventional manner silencing apparatus and has been improved 30 to 60%.
In addition, axial prestressing force has prevented the friction of silencing apparatus on compressor case.
Fig. 2 is a) to k) be illustrated on the silencing apparatus support flange 13 and between the support flange on the compressor case 23 in Fig. 1 by dotted line around the selective kind of possible form of implementation of contact area.
With respect to according to a) the perpendicular to axial direction and surface of contact that is provided with in the plane, at b) and c) shown in the surface of contact of circular cone ground moulding have following advantage, promptly they make silencing apparatus become easily simple with respect to the centering of compressor case in the assembling of silencing apparatus.In addition, all these three forms of implementation are feature with very simple manufacturability all.
Form of implementation d) to i) have good sealing effect and a good engagement positio damping effect.They all are the different stair-stepping forms of implementation of radially one-tenth, and have the surface of contact made from different costs.
For sealability and the damping capacity that obtains further to be enhanced, can replace step or groove/gear teeth to connect, as at k) as shown in corresponding groove or half slot, axially be pressed into the O type damping ring that constitutes by synthetic rubber or other suitable material.
Except first kind of form of implementation with the surface of contact that is provided with the simplest, the form of implementation shown in all has the shape of cooperation diametrically perpendicular to axial directionly, and this has additionally stablized silencing apparatus and compressor case.
