Abstract

The present invention relates to be assemblied in the support housing on the internal-combustion engine, be fixed with exhaust gas turbocharger on this housing, wherein turbine box is arranged in the cavity that is formed by support housing, and compressor shroud is positioned at outside this cavity.In order to use a small amount of as far as possible parts, and the exhaust gas turbocharger bearing housing is integrally formed on the supporting axle housing.

Description

Can be assembled to the support housing that is used for exhaust gas turbocharger on the internal-combustion engine
The present invention relates to a kind of for example disclosed support housing that is used for exhaust gas turbocharger that is assembled on the internal-combustion engine in DE3439738, wherein turbine box is arranged in the cavity that is formed by support housing, and compressor shroud is located at the outside of support housing.
On the described internal-combustion engine that load arranged of DE3479738C2, the turbine box of exhaust gas turbocharger is arranged in the cavity that is formed by support housing.The compressor shroud of exhaust gas turbocharger is positioned at outside the cavity.For fixing, and exhaust gas turbocharger is packed in the cylindrical groove on the support housing sidewall with its bearing housing, and be fixed on the support housing with screw.By the groove that is used to hold bearing housing of the two and half garden shapes that on top constitute with bottom, formed support housing thus.When taking off top, can carry out exhaust gas turbocharger is embedded installation in the lower recess, then assembling finishes after installing top.
According to DE3552695B1, the bearing housing of exhaust gas turbocharger constitutes the motor supporting simultaneously, and it is located between an elastic support and the internal-combustion engine.Thisly not only saved member, thereby had corresponding advantages as bearing housing but also as the double action of motor supporting.Yet, always may or not be necessary exhaust gas turbocharger is arranged on the internal-combustion engine with in the zone of bearing housing as the motor supporting.
Task of the present invention is, a kind of support housing that is used for exhaust gas turbocharger is provided, wherein turbine box is arranged in the cavity that is formed by support housing, the formation of this support housing is, comprise a small amount of as far as possible necessary member that is used for exhaust gas turbocharger and support housing, thereby cost is low, makes relevant production, warehouse keeping and installation procedure simplify weight saving.
For solving this task, the present invention has designed a kind of support housing of the above-mentioned type, and wherein the bearing housing with exhaust gas turbocharger is integrally formed on the supporting shell body wall.The formation of support housing is, fixing exhaust gas turbocharger and in cavity, settle the exhaust gas turbine case not only thereon, but also comprise bearing housing, in bearing housing, be equipped with the axle of exhaust gas turbocharger.Support housing also comprises the passage that lubricating bearings is essential, and as the containment vessel of bearing components.Because bearing housing no longer is the member that separates, has therefore reduced the number of components, thereby simplified production and installation process.Preferably will pour into a mould the support housing and the bearing housing global formation of structure.Therefore, inboard sensible support housing is made up of two-part at least.At this, proper is, does not have the gap in the zone of the described fixedly exhaust gas turbocharger by claim 2, so just can be separately with the bearing housing of exhaust gas turbocharger, and this is very useful for installation.Preferably, use the plane that parallels with the vertical shaft of support housing to cut apart support housing as described in the claim 3.Then, can before housing structure is combined into support housing, exhaust gas turbocharger be installed on the housing structure fully.As described in claim 4, because can comprise each housing parts of support housing of the bearing housing of global formation, therefore use the further limiting member quantity of supporting shell physical efficiency of symmetry with same tool production, further reduce production costs.
Embodiments of the invention are represented by accompanying drawing, and are described in detail hereinafter.This accompanying drawing represents to be equipped with the sectional drawing of the support housing of exhaust gas turbocharger.
Support housing cast shown in the sectional drawing forms, and in fact support housing 1 is made of two housing structures, and the flange of two members is to interconnect by screw.Form a cavity in the support housing 1 on can being assembled to the internal-combustion engine that figure do not show, do not have the turbine box 7 of exhaust gas turbocharger 2 in this cavity.The compressor shroud 6 of exhaust gas turbocharger 2 is positioned at outside the cavity that is made of support housing 1.Support housing is made of dual-layer wall, and interlayer has the cold water circulation.In order to be communicated with the exhaust piping that joins with the inlet or the outlet of turbine box 7, corresponding passage is set on support housing.The bearing housing 8 of exhaust gas turbocharger 2 is molded on the wall of support housing 1.In order to hold axle 5 sliding bearing jack 4 is set in the bearing supporting ring 3, axle 5 links to each other with the impeller of compressor and turbine.Thrust bearing 12 is used to absorb axial force.Compressor shroud 6 and turbine box 7 are screwed on support housing 1.Support housing 1 also further comprises the flow channel 9 and the flow pass 10 of lubricant oil, and lubricant oil is used for lubricating bearings.Flow pass 10 links to each other with pipeline 11, and pipeline 11 is led back lubricant oil in the collecting container of internal-combustion engine.Utilize the suitable construction of cooling chamber in the support housing 1, make the bearing cooling of exhaust gas turbocharger 2.
Support housing 1 obviously can be used for fixing a plurality of exhaust gas turbochargers.The support housing 1 that has the bearing housing 8 of global formation can make to be installed simply, and cost of production lowers, and has made things convenient for storehouse management owing to reducing member.Particularly advantageously be when the exhaust gas turbocharger of a plurality of symmetries is set, to constitute the support housing structure by the housing structure of symmetry.Therefore, the separation gap of housing structure should be positioned at outside the zone of fixing exhaust gas turbocharger, bearing housing is separated avoiding.This will make bearing housing extend on the gap of support housing and arrive a plane, and this plane parallels with the vertical shaft of support housing.

Claims (4)

1, a kind of support housing that is used for exhaust gas turbocharger that is assembled on the internal-combustion engine, wherein turbine box is arranged in the cavity that is formed by support housing, and compressor shroud is placed the outside of support housing, it is characterized in that, the bearing housing of exhaust gas turbocharger (2) is integrally formed on the wall of support housing (1).
2, support housing as claimed in claim 1 is characterized in that, on the support housing of being made up of a plurality of housing parts, has the gap of separation to extend between the housing parts in the wall district outside, fixing exhaust gas turbocharger (2) in this separation gap.
3, support housing as claimed in claim 2 is characterized in that, uses the extension plane that parallels with the vertical shaft of support housing that support housing (1) is cut apart, and exhaust gas turbocharger (2) is fixed on the sidewall.
4, support housing as claimed in claim 3 is characterized in that, support housing (1) is divided into the housing parts of two symmetries, and fixes two exhaust gas turbochargers (2) thereon at least symmetrically.
