Description
Technical field
The utility model relates to a kind of component of clutch, is specifically related to a kind of hub.
Background technique
Hub act as key player in automobile clutch.The effect of hub is the moment of torsion transmitting clutch drived disk assy.In clutch drived disk assy, the moment of torsion of friction plate passes to hub by spring, and hub, by passing to gearbox, guarantees the smooth transfer of moment of torsion.Conveniently demolition and maintenance, hub is made split type usually, but split type hub needs precision-fit when mounted, and so just need accurate processing, usual work in-process there will be error, if the attachment hole size of hub is less than normal, causes assembling difficulty.
Model utility content
The utility model provides a kind of easy for installation, cooperation hub closely.
To achieve these goals, the utility model adopts following technological scheme:
Comprise circular grip block, be provided with attachment hole in the middle part of grip block, in described attachment hole, isogonism is provided with keyway, dilatation joint is provided with between described keyway, on described grip block, isogonism is provided with four windows, and at grip block edge, also isogonism is provided with four grooves, is provided with a groove between described two windows.
Preferably, a dilatation joint is equipped with between described every two keyways.
Preferably, described keyway has eight, and corresponding dilatation joint also has eight.
The beneficial effects of the utility model are: hub is assembled on clutch drived disk assy by keyway, conveniently installs assembling, leave more surplus when dilatation joint can make installation assemble, even be processed with error also can carry out quick assembling.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model hub embodiment.
In figure, 1 is grip block, and 2 is attachment hole, and 3 is keyway, and 4 is dilatation joint, and 5 is window, and 6 is groove.
Embodiment
As shown in Figure 1, comprise circular grip block 1, be attachment hole 2 in the middle part of grip block 1, in attachment hole 2, isogonism is evenly equipped with keyway 3, and keyway 3 forms internal spline and driven disc assembles.Concrete, keyway 3 has eight, and between every two keyways, 3 have dilatation joint 4, and dilatation joint 4 also has eight.
During use, if there is error when the internal spline that attachment hole 2 interior spline 3 is formed coordinates with the external splines on driven disc, namely attachment hole 2 size is a bit larger tham driven disc external splines size, can be regulated, also can assemble by dilatation joint 4.On the plate face of grip block 1, isogonism offers four windows 5, and window 5 is for installing damping spring.The circumference profile of grip block 1 also has four grooves 6, has a groove 6 between every two windows 5.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
Claims (3)
1. hub, it is characterized in that: comprise circular grip block, attachment hole is provided with in the middle part of grip block, in described attachment hole, isogonism is provided with keyway, dilatation joint is provided with between described keyway, on described grip block, isogonism is provided with four windows, and at grip block edge, also isogonism is provided with four grooves, is provided with a groove between described two windows.
2. hub as claimed in claim 1, is characterized in that: be equipped with a dilatation joint between described every two keyways.
