Description
Technical field
The present invention relates to a kind of turbocharger housing, wherein, oil pipe is since first opening in the outside of the first housing parts, passes the first housing parts and passes into the bearing accommodating part that basically is hollow cylinder of the first housing parts at the second opening.In addition, the invention still further relates to a kind of turbosupercharger with this shells.
Background technique
Turbosupercharger be used for to improve the efficiency of internal combustion engine, and the kinetic energy that obtains the kinetic energy of waste gas streams and waste gas streams by turbo machine in turbosupercharger is used for air-fuel mixture is pressed into internal-combustion engine via the common axle of turbo machine and gas compressor.Can fill with relatively large mixture by this way the fixing swept volume of internal-combustion engine, when burning, can realize thus larger lift and therefore realize larger engine power.
In car, the axle of turbosupercharger or turbosupercharger has reached and has surpassed the rotational velocity that per minute 200,000 turns.In commerial vehicle, this value is in the order of magnitude that per minute 150,000 turns.The axle of turbosupercharger usually by sliding supported condition in turbocharger housing, just in the bearing accommodating part of turbocharger housing, discharge thus a large amount of frictional energies of hot form.In addition, turbocharger housing is between so-called hot housing and the cooled case.In hot housing, waste gas streams is directed on the turbo machine, is wherein additionally transferred heat on the hot housing by hot waste gas stream.At run duration, in hot housing typically 1050 ℃ be in leadingly, and in the compressed cooled case of air-fuel mixture, approximately 20 ℃ temperature is in leading.
For those reasons, so need to be by near the water cooling enduringly and especially cooling turbine pressurized machine housing bearing accommodating part.Must prevent from being transferred to cooled case from the heat of waste gas streams via turbocharger housing on the one hand, this typically also can occur via axle.On the other hand, suitable is to derive the frictional heat that forms in the sliding bearing.If then there is the risk of the impaired and air-fuel mixture premature ignition in cooled case of sliding bearing in the cooling failure in the turbocharger housing.
In WO2009/013332A3, disclose a kind of turbosupercharger with housing, wherein be provided with housing, be used for holding the sliding bearing for the axle of turbosupercharger.This housing is comprised of foundry goods basically, and foundry goods comprises the water pipe for the cooling bearing accommodating part.For the major part of water pipe, housing surrounds this water pipe fully on radial direction and axial direction.
Although the turbocharger housing that is made of casting metals has outstanding thermal conductivity, also have large weight and just will take a lot of trouble to have caused very high manufacture cost aspect the integrated but indispensable cold water pipe.
Summary of the invention
Therefore, task of the present invention is a kind of lighter turbocharger housing of explanation, and it can more simply and more inexpensively be made, and can not make the functional deteriorated of turbocharger housing at this.
This task solves in the following way by the turbocharger housing of the described type of beginning: turbocharger housing has the second housing parts and the common cold water pipe that is provided for the cooling bearing accommodating part that forms of this two housing parts that is attached on the first housing parts.
According to the present invention, the form that is provided with in turbocharger housing is the oil supplying device of at least one oil pipe, and this oil supplying device is used to the bearing fuel feeding in the bearing accommodating part that is arranged in hollow cylinder.For this reason, the first housing parts has the first opening, and the first aperture arrangement is on the outside of the first housing parts.Oil pipe is from this first opening, and this oil pipe passes the first housing parts.Oil pipe can for example be introduced or be configured in the first housing parts by corresponding boring.Oil pipe finishes and passes into the bearing accommodating part that basically is hollow cylinder at the second opening of the first housing parts.Also once for example holed by cutting and be configured in the first housing section office in the bearing accommodating part.In case of necessity, have different grooves or the structure of sub-circular at the internal surface of the hollow cylinder of bearing accommodating part, the bearing accommodating part is different from the shape that basically is hollow cylinder in case of necessity thus.Therefore, the second opening be oil pipe to the mouth that passes into of bearing accommodating part, can be sliding bearing or the rolling bearing fuel feeding of turbosupercharger thus.
In the turbosupercharger of sliding bearing, for example in the situation that the corresponding pressure of use is pressed into the bearing accommodating part from the outside, wherein lubricant medium has formed so-called squeeze film and in axial direction has been moved further gradually and has finally left sliding bearing lubricant medium (oil) between bearing accommodating part and sliding ring.
According to the present invention, turbocharger housing also has the second housing parts except the first housing parts, and the second housing parts is attached on the first housing parts.Attached can the realization by known joining technique, for example welding, bonding, crimping and/or soldering.Laser bonding is especially suitable, because guaranteed the industrialization manufacturing with the very short manufacturing endurance.Be attached to the first housing parts by the second housing parts and formed the cold water pipe that is provided for the cooling bearing accommodating part.In other words, another part of the outer surface of the part of the outer surface of the first housing parts and the second housing parts has formed the inwall of cold water pipe jointly.Advantageously, cold water pipe needn't be made with bothersome casting technique, but two according to housing parts of the present invention can both with common cutting method or forming technique be made and be bonded together after processing.
Advantageously, utilize for example boring of cutting method, turning and/or milling to make the first housing parts by wrought product.Alternatively, the first housing parts also can be made by sheet material, wherein must be noted that: guarantee heat flow or cooling effect.The second housing parts can be saved into local the manufacturing equally in the following way especially: the second housing parts is configured to sheet material spare, especially is configured to the sheet material spare of cold forming.Because applicable cutting method being arranged, also possiblely be, (comparing with the cooling chamber in traditional casting) increased the cross section of the cold water pipe with very little manufacturing tolerances significantly, and externally size keeps can advantageously realizing until four times of large cold water flows in the identical situation thus.
In a favourable form of implementation, attached to the first housing parts of the second housing parts also formed by two seams along the cold water pipe trend.Seam is the product of one of applied joining technique.In the situation that welding, seam for example is weld seam, and in the situation that bonding, seam is such as being cemented side seam etc.Advantageously, opposite with sand casting process, the hollow space of cold water pipe needn't be removed gravel afterwards under high hydraulic pressure remaining.Boring can not occur in addition, even especially and remove core.
Seam must not only be guaranteed the structure stability of turbocharger housing but also must realize the sealing of cold water pipe, leak so that get rid of cold water under the condition that can exist when operation.Therefore, seam also should have sealing function.
If the second housing parts is partially or even wholly formed by sheet material, then do not need to make heat flow through seam, because sheet material can absorb less heat owing to its little thickness.Therefore, cooling is undertaken by main water pipe through the first housing parts.Alternatively, the first housing parts and the second housing parts are embodied as wrought product, and two housing parts can hold or conduct larger hot-fluid thus, and this application according to turbosupercharger is essential in case of necessity.Alternatively, for example can make the first housing parts and the second housing parts by sheet material in the situation that heat load is less.
Advantageously, the first housing parts is provided for being connected with cooled case and/or hot housing.For the assembling reason meaningfully, cooled case, hot housing and turbocharger housing are screwed each other.Yet the connection of these housings also can realize by other known fixing devices.And importantly, the transfer of torque that may should not be participated in screwing by the housing parts that sheet material consists of of turbocharger housing.Therefore, when getting around the housing parts of being made by sheet material when need to be fixedly, the spacer sleeve that for example is used for the first housing parts is tightened onto on hot housing or the cooled case is significant.Therefore spacer sleeve has reflected the axial width of the second housing parts basically, and this axial width must be overcome fixedly the time.Advantageously, so the second housing parts is because total little heat transmission that must or only not participate in rarely from hot housing to turbocharger housing of surface of contact, but owing to having spacing and spacer sleeve to form another kind of favourable isolation.In addition, spacer sleeve is particularly useful for being absorbed in engaging force and the vibration force that can form when installing or moving.
According to applicable cases, can not use spacer sleeve and implement the second housing parts (for example double wall or analog) more stable, so that can be with the tensioning between the first housing parts and hot housing of the second housing parts.
In a favourable form of implementation, the 3rd housing parts is provided for being formed for the first housing parts is fixed to fixed adapter on the cooled case.In principle, the first housing parts is constructed so that and can directly be fixed on the cooled case.Yet, because the 3rd housing parts can be optionally equally by sheet material forming, so formed another cost advantage based on many property.The 3rd housing parts on the first housing parts be fixed on this can be by screwing or the mechanical connection of laser bonding or arbitrary other types is realized.
In a favourable form of implementation, fixing device is set, such as bolt, not only be used for being tightened onto the first housing parts on the hot housing but also being used for the 3rd housing parts is fixed to the first housing parts.This has simplified the fixing of turbocharger housing in form of implementation two-piece type or multi-part type by the mode that can use same fixing device for this reason.
Not only can use in the turbosupercharger of rolling bearing but also can use in the turbosupercharger of sliding bearing according to turbocharger housing of the present invention.In addition, turbocharger housing can be by forming more than parts two or three, and wherein each part can arrange for one or more functions specially.Importantly, one of housing parts that forms cold water pipe has enough quality in order to guarantee the optimal heat conduction of cold water pipe.
Other favourable structural schemes of the present invention and advantageous modification are known from description of drawings and/or dependent claims.
