Description

A kind of flywheel structure
Technical field
The utility model relates to a kind of flywheel structure.
Background technique
At present, the truck type of coupling automatic transmission case, its flywheel casing and case of transmission all need to be undertaken being connected (see accompanying drawing 1) by specific flywheel casing fastener rings, this kind of Placement can cause integral power assembly longer and heavy, and directly cancelling this flywheel casing fastener rings, that automatic transmission case can be made to move past in flywheel casing direction is many, but existing flywheel structure is thicker, take up space larger (see accompanying drawing 2 and accompanying drawing 3), car load automatic transmission case can be caused, flexibly connect disc portion and engine flywheel is interfered and cannot run well, and can use without ready-made structure at present, the vehicle of therefore mating automatic transmission case at present all continues to use this comparatively heavy structure of flywheel casing fastener rings.
Model utility content
The technical problems to be solved in the utility model is for above-mentioned defect, provides a kind of reduction flywheel thickness, and then shortens the flywheel structure of power assembly length.
In order to solve the problems of the technologies described above, the utility model comprises flywheel body, the middle part of described flywheel body is provided with the through hole passed for bent axle, the excircle of flywheel body is provided with gear ring, the outer ring of flywheel body is equipped with multiple flexible disk bolt hole, its structural feature is: the outside in the middle part of described flywheel body is provided with and is connected and the linkage section of evagination with flywheel casing, inner side in the middle part of described flywheel body is provided with and is connected and the boss of convex with flywheel ABAP Adapter, described boss is equipped with multiple flywheel ABAP Adapter mounting hole, the middle part of described boss is provided with annular recess, described annular recess is equipped with multiple crank shaft bolt mounting hole.
The position of the corresponding multiple crank shaft bolt mounting hole of inwall of described annular recess is recessed to the direction of boss.
Described through hole and linkage section, boss, annular recess is concentric arranges.
Flexible disk bolt hole on described flywheel body outer ring is at least provided with 15.
Described gear ring shrink-on is on the excircle of flywheel body.
Compared with prior art the utility model has the following advantages: flywheel body integral thinned, thinning thickness is the thickness of fastener rings, cancel the use of fastener rings, speed changer can move to the direction of flywheel body, displacement distance is the thickness of fastener rings, therefore can shorten the length of power assembly, after flywheel body is thinning, flywheel adapter card is contained on the boss of flywheel body; The position of the corresponding multiple crank shaft bolt mounting hole of inwall of annular recess is recessed to the direction of boss, facilitates the installation of crank shaft bolt, ensure that the intensity of flywheel simultaneously; Flexible disk bolt hole on flywheel body outer ring increases, and ensures the stability that flexible disk is installed; Adopt the mode of shrink-on to be connected between flywheel with gear ring, save bolts assemblies space, and the utility model alleviates overall engine weight, reduce the manufacture cost of motor, structure is simple, and it is convenient to assemble.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is the assembling relationship figure of flywheel and gearbox in prior art;
Fig. 2 is the structural representation of flywheel in prior art;
Fig. 3 be in Fig. 2 A-A to sectional view;
Fig. 4 is the assembling relationship figure of flywheel and gearbox in the utility model;
Fig. 5 is the structural representation of flywheel in the utility model;
Fig. 6 be in Fig. 5 B-B to sectional view.
Embodiment
With reference to accompanying drawing, this flywheel structure comprises flywheel body 1, and the middle part of flywheel body 1 is provided with the through hole 8 passed for bent axle.The excircle of flywheel body 1 is provided with gear ring 9, and in the present embodiment, gear ring 9 shrink-on is on the excircle of flywheel body 1, eliminating on former flywheel for connecting 12 fixed holes of gear ring 9, saving bolts assemblies space.In original structure, flywheel body 1 is arranged between flywheel casing 11 and gearbox 12, fastener rings 13 is installed between flywheel casing 11 and gearbox 12, in the present embodiment, flywheel body integral thickness reduces, the thickness reduced is the thickness of fastener rings 13, therefore speed changer 12 can the direction of flywheel body 1 in the past move, speed changer 12 is bolted on flywheel casing 11, and the distance of speed changer 12 movement is the thickness of fastener rings 13.The outer ring of flywheel body 1 is equipped with multiple flexible disk bolt hole 7 for placing flexible disk bolt, flexible disk 20 is connected with flywheel ABAP Adapter 19 and speed changer 12 respectively by bolt, and flywheel ABAP Adapter 19 and flywheel body 1 are connected by bolt, speed changer 12 moves the bolt needing increase by three fixing flexible dishes between rear flexible disk 20 and flywheel body 1, therefore the flexible disk bolt hole 7 in the present embodiment on flywheel body 1 outer ring is at least provided with 15, thus fixedly secures flexible disk 20.Outside in the middle part of flywheel body 1 is provided with and is connected and the linkage section 2 of evagination with flywheel casing 11, is fixed between flywheel body 1 and flywheel casing 11 by bolt of flywheel 18.Inner side in the middle part of flywheel body 1 is provided with and is connected and the boss 3 of convex with flywheel ABAP Adapter 19, and in the present embodiment, the external diameter of boss 3 and the internal diameter of flywheel ABAP Adapter 19 front end adapt, thus flywheel ABAP Adapter 19 is clamped on boss 3.Boss 3 is equipped with multiple flywheel ABAP Adapter mounting hole 4, utilizes bolt flywheel ABAP Adapter 19 to be fixed in flywheel body 1.The middle part of boss 3 is provided with annular recess 5, and annular recess 5 is equipped with multiple crank shaft bolt mounting hole 6, in the present embodiment, crank shaft bolt mounting hole is at least provided with 9, and bent axle is fixed by crank shaft bolt through after through hole 8.The position of the corresponding multiple crank shaft bolt mounting hole 6 of inwall of annular recess 5 is recessed to the direction of boss 3, forms the recessed surface that 9 semicircles are connected, facilitates the installation of crank shaft bolt, ensure that the intensity of flywheel body 1 simultaneously.
Through hole 8 and linkage section 2, boss 3 in the present embodiment, annular recess 5 is concentric arranges.
Concrete Power output mode is: piston up-down in motor, drive the outside outputting power of connecting rod, by flywheel body 1, power is passed to flexible disk 20 by flywheel ABAP Adapter 19 again, flexible disk 20 belongs to elastic element, reduces the impact of vibration on speed changer of motor in the process of power transmission; Power arrives speed changer 12 by flexible disk 20 again, by the automatically controlled and hydraulic pressure installation in speed changer 12, completes the output of engine power.
By the cancellation of the thinning and fastener rings of flywheel body 1 in the utility model, shorten the length of power assembly, alleviate overall engine weight, reduce the manufacture cost of motor, and structure is simple, it is convenient to assemble.
The utility model is not limited to above-mentioned embodiment, those skilled in the art, under the prerequisite not departing from spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
