Description
Technical field
This utility model is related to auto parts and components field, specifically a kind of double mass flywheel positioned by hub.
Background technology
There is complex structure in existing double mass flywheel, punch forming difficulty is larger, and the shortcoming of high cost, while secondary
The transmission efficiency of flywheel load is also universal relatively low.
The content of the invention
, to overcome the deficiencies in the prior art, design is a kind of simple and compact for structure and can effectively reduce punching press hardly possible for this utility model
The double mass flywheel positioned by hub of degree.
For achieving the above object, a kind of double mass flywheel positioned by hub is designed, including primary flywheel and secondary flies
Wheel, is characterized in that：The primary flywheel includes primary flywheel shell, hub, pad and rivet, sets on the downside of primary flywheel shell
There is hub, on the upside of primary flywheel shell, be provided with pad, primary flywheel shell, adopt rivet interlacement between pad and hub, just
Fixed using fixing bolt between level flywheel and engine crankshaft；Between the lower surface of the upper surface of the hub and secondary flywheel
It is provided between the inner surface of axial bushings, the outer surface of hub and secondary flywheel and is provided with radial direction bushing, hub and engine crankshaft
External centring coordinate.
Described secondary flywheel is provided with via, and via is located at the top of fixing bolt.
Pitch circle diameter of the diameter of described radial direction bushing less than bolt.
The pitch circle diameter with diameter greater than bolt of described axial bushings.
Compared with the existing technology, by axial direction, the secondary flywheel load of radial direction bushing transmission, simple structure is tight for this utility model
Gather, can effective reduces cost；By hub and engine crankshaft be cylindrical and primary flywheel shell centering so that primary flywheel knot
Structure is simple, so as to reduce punching press difficulty.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Referring to Fig. 1, wherein, 1 is secondary flywheel, and 2 is radial direction bushing, and 3 is hub, and 4 is via, and 5 is axial bushings, and 6 are
Pad, 7 is rivet, and 8 is engine crankshaft, and 9 is fixing bolt, and 10 is primary flywheel shell, and 11 is primary flywheel.
Specific embodiment
This utility model is described further below according to accompanying drawing.
As shown in figure 1, the primary flywheel 11 includes primary flywheel shell 10, hub 3, pad 6 and rivet 7, it is primary to fly
The downside of wheel housing 10 is provided with hub 3, and the upside of primary flywheel shell 10 is provided with pad 6, primary flywheel shell 10, pad 6 with
Connected using rivet 7 between hub 3, fixed using fixing bolt 9 between primary flywheel 11 and engine crankshaft 8；The hub 3
Upper surface and the lower surface of secondary flywheel 1 between be provided with axial bushings 5, the inner surface of the outer surface of hub 3 and secondary flywheel 1
Between be provided with radial direction bushing 2, hub 3 is coordinated with the external centring of engine crankshaft 8.
Described secondary flywheel 1 is provided with via 4, and via 4 is located at the top of fixing bolt 9.
Pitch circle diameter of the diameter of described radial direction bushing 2 less than bolt 9.
The pitch circle diameter with diameter greater than bolt 9 of described axial bushings 5.
When this utility model is used, by rivet 7 by primary flywheel shell 10 (can be rigidity or flexible), hub 3,
The riveting of pad 6 is primary flywheel entirety, primary flywheel is integrally connected on engine crankshaft 8 by fixing bolt 9, secondary to fly
There is the convenient installation fixing bolt 9 of via 4 on wheel 1.The axial load of secondary flywheel 1 is transferred to into pad 6 by axial bushings 5.
By radial direction bushing 2 by the radial load transfer of secondary flywheel 1 to hub 3.Matched somebody with somebody with the cylindrical of engine crankshaft 8 by hub 3
Centering is closed, hub 3 is similarly radial direction bushing 2 and provides the rubbing surface for coordinating.Secondary flywheel 1 is radial direction bushing 2 simultaneously and axially serves as a contrast
Set 5 provides rubbing surface.Pitch circle diameter of the diameter of radial direction bushing 2 less than fixing bolt 9, axial bushings 5 with diameter greater than solid
Determine the pitch circle diameter of bolt 9.In this structure primary flywheel shell 10 can be rigid flywheel can also be flexible flywheel.
