Embodiment
Below, with reference to accompanying drawing, mode of execution of the present utility model is described.
Turbosupercharger 10 shown in Fig. 1 is to utilize the energy of internal-combustion engine 1 exhaust air amount to be carried out to the turbosupercharger of supercharging.Internal-combustion engine 1 is for example 4 cylinder gasoline engines.The body of internal-combustion engine 1 possesses: the cylinder block 2 of each cylinder array configuration vertically and the cylinder head 3 engaging with the upper end of cylinder block 2.On cylinder head 3, be connected with the discharge manifold 4 that the tail gas that the firing chamber from each cylinder is discharged pools together.Discharge manifold 4 is connected with exhaust passage 6.
In internal-combustion engine 1, be inserted in piston in each cylinder and be subject to the pressure-acting of the combustion gas that produce in burning Indoor Combustion, and reciprocating.The to-and-fro motion of each piston is converted to rotatablely moving of bent axle (internal-combustion engine 1 output shaft).The tail gas of discharging from the firing chamber of each cylinder is deflated menifold 4 and collects, be transported to turbosupercharger 10.
Turbosupercharger 10 possesses: flowed into the powered of tail gas of exhaust passage 6 and the turbine wheel that rotates, will flow into air intake passage 5 air amount forced conveyance to the compressor impeller of each cylinder chamber and connect the turbo-charger shaft of turbine wheel and compressor impeller.Turbine wheel is incorporated in the turbine shroud 11 that is arranged at exhaust passage 6.Compressor impeller is incorporated in the compressor housing 12 that is arranged at air intake passage 5.Middle casing 13 is clipped between turbine shroud 11 and compressor housing 12.
The upstream-side-end 111 of turbine shroud 11 is connected with the exhaust collection portion 41 of discharge manifold 4.The end of downstream side 112 of turbine shroud 11 is connected with outlet pipe 7.On the position being connected with outlet pipe 7 of end of downstream side 112, form flange 113.Flange 113 is fastenedly connected by the fastening pieces such as bolt and the flange 71 that is arranged on outlet pipe 7 upstream-side-end.
Turbosupercharger 10 is bearing on the body of internal-combustion engine 1 by support 20.Support 20 is made by iron plate.The end, one end 201 of support 20 is fixed on the cylinder block 2 of internal-combustion engine 1 by fastening pieces such as bolts.The other end end 202 fasteners of support 20 are fixed on turbine shroud 11.
Particularly, as shown in Figure 2, stud 21 and nut 22 that the other end end 202 of support 20 is used as fastening piece are fixed on the flange 113 of turbine shroud 11.On the flange 113 of turbine shroud 11, be screwed with two studs 21.Two stud 21 disposed adjacent but leave to each other certain intervals.On each stud 21, be assembled with successively: the other end end 202, packing ring 23 and the nut 22 of support 20.
When assembling, two studs 21 are first installed on flange 113, then two bolt-inserting holes 203 of the other end end 202 that is formed on support 20 are inserted in respectively on each stud 21, thereafter the packing ring of two hollows 23 are inserted in respectively on each stud 21, and screw togather with nut 22 respectively.Like this, utilize stud 21 and nut 22 as fastening piece, support 20 is fixed on the flange 113 of turbine shroud 11.In addition, also stud 21 can be screwed in the flange 113 of turbine shroud 11 and the flange 71 of outlet pipe 7.
At this, between support 20 and nut 22, clip packing ring 23.Stud 21 and nut 22 as fastening piece for example, are made up of Austenitic stainless steel (SUS304) member respectively.Packing ring 23 is made up of the material identical with stud 21 and nut 22 linear expansion coeffcients.Specifically, the same with stud 21 and nut 22, packing ring 23 also for example, is processed by Austenitic stainless steel (S U S304), and its linear expansion coeffcient is for example 17 × 10
-6［ 1/ DEG C ］.
Adopt present embodiment, the packing ring 23 being clipped between fastening piece (stud 21 and nut 22) and support 20 can absorb the line differential expansion between fastening piece and support 20.Therefore,, even if do not adopt expensive material that resistance to heat the is good material as support 20, the fastening piece axial force that also can suppress to cause because of the line differential expansion between fastening piece and support 20 under the condition of high temperature declines.In addition, support 20 is fabricated from iron, and therefore, compared with using the situation of the stainless support 20 of Austenitic, can reduce costs.
Fig. 3 is the figure that represents the relation between Tightening moment (transverse axis of Fig. 3) and the axial force (longitudinal axis of Fig. 3) of fastening piece (stud 21 and nut 22).Solid line L1 in Fig. 3 represents the relation at fastening initial stage; Dotted line L2 represents to adopt the relation under the condition of high temperature in the situation of packing ring 23; Dot and dash line L3 represents not adopt the relation under the condition of high temperature in the situation of packing ring 23.As shown in Figure 3, no matter adopted packing ring 23 or do not adopted packing ring 23, under the condition of high temperature, axial force all can decline, and still, has adopted packing ring 23 compared with not adopting packing ring 23, and the amplitude that the axial force under the condition of high temperature declines reduces.
For example, when the Tightening moment at initial stage is 60 ［ Nm ］, adopted packing ring 23 compared with not adopting packing ring 23, the amplitude that the axial force under the condition of high temperature declines has reduced 5 ［ k N ］.Particularly, while not adopting packing ring 23, under the condition of high temperature, it is large that the line differential expansion between the fastening piece being made up of Austenitic stainless steel and the support 20 that is made up of iron becomes, and only can guarantee the axial force of approximately 10 ［ k N ］.And in contrast to this, adopt in the situation of packing ring 23, the packing ring 23 being made up of Austenitic stainless steel is clipped between fastening piece and support 20, therefore, under the condition of high temperature, the line differential expansion between fastening piece and support 20 shortens, thereby can guarantee the axial force of approximately 15 ［ k N ］.
Below, modified embodiment of the present embodiment is described.
Except adopting the structure shown in Fig. 2, also multiple packing rings 23 can be processed as one.In the variation 1 shown in Fig. 4, two packing rings 23 are linked and are integrated by linking department 24.Adopt this structure, can reduce the number of part.In addition can suitably adjust corresponding to the number of the fastening piece (stud 21 and nut 22) of installing on turbine shroud 11, the number of packing ring 23.
In addition, packing ring 23 also can be installed on support 20 in advance.In the variation 2 shown in Fig. 5, in the end of the direction of insertion side of packing ring 23, be formed with the minor diameter part 231 being integrated with packing ring.This minor diameter part 231 is pressed in the through hole 204 of support 20.Like this, just, packing ring 23 and support 20 can be assembled into one.In addition, variation 3 that can also be is as shown in Figure 6 such, adopts annular pin 25 as fixed component, and packing ring 23 and support 20 are assembled into one.
In the case, when assembling, first stud 21 is arranged on the flange 113 of turbine shroud 11, then on stud 21, assembling is assembled all-in-one-piece support 20 with packing ring 23, nut 22 and stud 21 screwed togather, just support 20 can be fixed on the flange 113 of turbine shroud 11 thereafter.Adopt this structure, just there is no need separately to fill again packing ring 23, thereby can easy installation exercise.
Above, as fastening piece, although enumerated the example that adopts stud 21 and nut 22, also can adopt other the fastening piece such as hex head bolt.In addition, enumerated the example that forms fastening piece (stud 21 and nut 22) and packing ring 23 with Austenitic stainless steel component although above, be not limited to this, good member forms above-mentioned fastening piece and packing ring 23 also can to adopt other resistance to heats.In addition, enumerate although above support 20 has been fixed on to the example on the flange 113 of turbine shroud 11, also support 20 can be fixed on to other positions beyond the flange 113 of turbine shroud 11.
