Technical field
The present invention relates to automotive engine applications, particularly a kind of structure simple, easy, non-damageable flywheel shell of diesel engine mounting structure is installed.
Background technique
In prior art, the cylinder block of motor mainly contains 3 kinds of structures, formula of rising on one's feet, planer-type and dark skirt-type, tunnel type.The motor that some claimed structure rigidity is stronger can adopt tunnel type cylinder block.Tunnel type cylinder block is concrete as shown in Figure 1, and it specifically comprises bent axle 1A and thrust main bearing seat 2A, and the installation of thrust main bearing seat 2A must penetrate from spindle hole one end of cylinder block 3A, and just as passing through tunnel, therefore tunnel type cylinder block also gains the name.For effectively limiting the axial float of bent axle 1A, need design fixed base 4A to be coupled together by thrust main bearing seat 2A and cylinder block 3A, the central bore of this fixed base 4A is installed oil sealing 6A simultaneously and is leaked in flywheel casing 5A in cylinder block 3A to avoid machine oil.
But there is following problem in above-mentioned design: complex structural designs, installation difficulty are large, maintaining costly.
Summary of the invention
The object of this invention is to provide a kind of structure simple, easy, non-damageable flywheel shell of diesel engine mounting structure is installed.
Technological scheme provided by the invention is: a kind of flywheel shell of diesel engine mounting structure, comprise housing, cylinder block, the bent axle be arranged in cylinder block, described cylinder block is provided with thrust main bearing seat, described housing is provided with center hole, and described housing is fixedly connected with thrust main bearing seat by the first connection part; Described housing is fixedly connected with cylinder block by the second connection part, and described center bore inner wall is provided with the first black box being formed with bent axle and be tightly connected.
In above-mentioned flywheel shell of diesel engine mounting structure, the first described connection part and the second connection part form by bolt hole and the bolt that coordinates with bolt hole.
In this programme, first connection part and the second connection part do not repel the Placement adopting other, internal thread and outside thread as being provided with coupling on housing and thrust shaft block carry out fastening, and just this Placement is structurally more complicated, require higher to accuracy.
In above-mentioned flywheel shell of diesel engine mounting structure, the first described black box is oil sealing.
In this programme, the first black box is not defined as oil sealing, and the optional sealing means in other related domains is all feasible.
In above-mentioned flywheel shell of diesel engine mounting structure, described housing is distributed with many stiffening ribs.
In above-mentioned flywheel shell of diesel engine mounting structure, between described housing and cylinder block, be provided with the second black box for the junction plane between seal casinghousing and cylinder block.
In above-mentioned flywheel shell of diesel engine mounting structure, the second described black box is pad or sealant layer.
The present invention is after employing technique scheme, and its beneficial effect had is:
(1) utilize the housing of flywheel casing as the intermediate connecting thrust main bearing seat and cylinder block in this programme, the fixed base of the fixing thrust main bearing seat of tradition can be saved like this, structure to motor particularly diesel engine simplify, and structural simplification brings the convenience installed.
(2) the first black box is installed in center hole by this programme, can play good seal action, prevents the machine oil in cylinder block from entering in the housing of flywheel casing, improves the working life of diesel engine.
(3) this programme is in order to prevent the oil leakage in cylinder block further and cushion the vibrations suffered by flywheel casing, adopts the second black box being arranged on housing and cylinder block, and sealing and cushioning effect have excellent, make it not fragile.
Accompanying drawing explanation
Fig. 1 is the structural representation of the tunnel type cylinder block described in background technique of the present invention;
Fig. 2 is the schematic diagram of the flywheel shell of diesel engine mounting structure of the embodiment of the present invention 1.
The component that in Fig. 1 and Fig. 2, each label is corresponding are: 1, housing; 2, center hole; 3,2A, thrust main bearing seat; 4, first connection part; 5,3A, cylinder block; 6, second connection part; 7, first black box; 8, stiffening rib; 9, second black box; 10,1A, bent axle; 4A, fixed base; 5A, flywheel casing; 6A, oil sealing.
Embodiment
Below in conjunction with embodiment, technological scheme of the present invention is described in further detail, but does not form any limitation of the invention.
Embodiment 1:
As shown in Figure 2, a kind of flywheel shell of diesel engine mounting structure, comprise housing 1, described housing 1 is provided with center hole 2, described housing 1 is fixedly connected with thrust main bearing seat 3 by the first connection part 4, and described housing 1 is fixedly connected with cylinder block 5 by the second connection part 6, and described center hole 2 inwall is provided with the first black box 7, under the effect of the first black box 7, thrust main bearing seat 3 and housing 1.The shape of housing 1 is consistent with the shape of the housing of flywheel casing conventional in related domain, and for having the tubular structure of circular inner fovea part, its one end is attachment face, and center hole 2 is arranged on the center of attachment face, and inner fovea part is flywheel receiving cavity.
Specifically in the present embodiment, the bolt that the first described connection part 4 and the second connection part 6 include bolt hole and coordinate with bolt hole.Bolted feature is that stable connection, field-strip are convenient, and other Placements in certain related domain are not repelled outside the present embodiment yet.
In the present embodiment, the first described black box 7 is oil sealing, adopts the advantage of oil sealing to be, effectively by needing the parts of lubrication to isolate with parts of exerting oneself, can be unlikely to allow oil seepage.
In order to improve join strength and the mechanical strength of this programme further, in the housing 1 of flywheel casing, be provided with stiffening rib 8.
In the present embodiment, stiffening rib 8, first connection part 4, second connection part 6 acts synergistically, housing 1 can be improved further as structure stability when connecting the intermediate of thrust main bearing seat 3 and cylinder block 5, reduce the axial float of bent axle 10 to the impact of the structure stability of housing 1.
In a particular application, one is most preferably arranged between described housing 1 and cylinder block 5 for the second black box 9 of the junction plane between seal casinghousing 1 and cylinder block 5, as pad or sealant layer.The advantage of such setting has two, first, can play the effect of the junction plane between good seal casinghousing 1 and cylinder block 5, in addition, contributes to reducing the vibrations suffered by housing 1, improves the structure stability of housing 1.
In as installed process, the assembling method of diesel engine conveniently carries out, and when after the penetrating from cylinder block 5 spindle hole one end of thrust main bearing seat 3, is bolted in thrust main bearing seat 3 and cylinder block 5 by the housing 1 of flywheel casing.Certainly, the housing 1 of flywheel casing in a pre-installation, needs on center hole 2, to install oil sealing in advance.
Compared to the structure of the traditional cylinder block shown in Fig. 1, in the present embodiment, after dispensing the fixed base of the fixing thrust main bearing seat 3 of system, the structure of producing the diesel engine obtained is simplified, and Placement is firm, and maintenance process simulation is also very convenient.
