Embodiment
Below, referring to the drawings, the concrete structure of the present invention is illustrated.
First, Fig. 1 is to exemplify the constant velocity cardan joint 10 and the figure of wheel hub 20 being combined using the present invention, such as the figure
It is shown, in the present invention, as the packing ring between the foreign steamer 12 and wheel hub 20 of constant velocity cardan joint 10, it is attached to constant velocity universal
Between the end surface of foreign steamer 12 and the rear end surface of wheel hub 20 of section 10.
That is, as shown in Fig. 2 the attachment washer 30 of the present invention is used as in central part formed with more than constant velocity cardan joint 10
The diameter of axle 11 internal diameter opening portion 31 tabular ring body, front and back is close to the constant velocity cardan joint of wheel hub 20 respectively
The outboard end surface of the axle 11 of the rear end surface of 10 sides and the foreign steamer 12 of constant velocity cardan joint 10.
As shown in Figures 2 and 3, the opening portion 31 for being formed at the central part of the attachment washer 30 of the present invention is formed as, and has
The substantially greater than internal diameter of the diameter of axle 11, especially its internal diameter be also substantially greater than and be formed at connection between axle 11 and foreign steamer 12
The diameter of the wide diameter portion of the axle 11 in portion, therefore directly contacting between axle 11 and attachment washer 30 is avoided, thus prevent in axle 11
The transverse shifting of caused attachment washer 30 when directly being contacted between attachment washer 30.
As shown in figure 1, the axle 11 of constant velocity cardan joint 10 is substantially being inserted wheel hub by constant velocity cardan joint 10 and wheel hub 20
Axially fastening screw and connect along axle 11, is thus delivered to wheel hub by the revolving force of constant velocity cardan joint 10 in the state of 20
20, therefore the mechanics tie point between constant velocity cardan joint 10 and wheel hub 20 is the end of axle 11, as shown in Figure 1, with reference to shape
Inevitably formed between the outer peripheral face of the rearward end of the axle 11 of state and the inner peripheral surface of wheel hub 20 for ensuring assembling operation
Clearance, therefore can occur in the running of automobile using the end of the axle 11 of constant velocity cardan joint 10 as the fine inclined of fulcrum
The heart rotates or vibration.
In the case where axle 11 directly contacts with attachment washer 30, the eccentric rotary or vibration are passed to connection as former state
Packing ring 30, the power of the movement of attachment washer 30 is laterally made with applying repeatedly on the axially vertical of axle 11 or even the direction intersected,
As long as and the transverse shifting of attachment washer 30 as occurring, even slightly occur, then can cause attachment washer 30 with etc.
Bonding state between fast universal joint 10 and wheel hub 20 becomes loose, therefore fully expands the opening of attachment washer 30 in the present invention
The internal diameter in portion 31, so as to block directly contacting between attachment washer 30 and axle 11, particularly also block the rear end of axle 11 expanding
Contact at portion.
That is, in the present invention, it is preferred to be, the rear end that the internal diameter of the opening portion 31 of attachment washer 30 is not only greater than axle 11 is expanding
The diameter in portion, but also the internal diameter of the rear end clearance forming portion more than wheel hub 20.
Such attachment washer 30 of the invention is set as follows：As illustrated in fig. 3 temporarily in constant velocity cardan joint 10
The end of foreign steamer 12 be close to the back side of attachment washer 30 and as illustrated in fig. 2 insert the axle 11 of constant velocity cardan joint 10 after combining
Enter wheel hub 20 and combine screw.As described above, the internal diameter of the opening portion 31 of the attachment washer 30 of the present invention is more than the diameter of axle 11, because
This forms prominent ring body 32 in the gabarit of attachment washer 30, so that when carrying out assembling operation, attachment washer 30 is fixed into gabarit
Accurate position on 12.
I.e., as shown in Figures 2 and 3, attachment washer 30 gabarit formed with the foreign steamer 12 with constant velocity cardan joint 10
Axle 11 outboard end the consistent internal diameter of diameter protrusion ring body 32, by the way that the protrusion ring body 32 is attached into constant velocity universal
The end of the foreign steamer 12 of section 10, so that before constant velocity cardan joint 10 and wheel hub 20 are assembled, it is also possible that attachment washer 30
Constant velocity cardan joint 10 is concentrically affixed to axle 11.
So, it is installed on of the invention between the leading section of the foreign steamer 12 of constant velocity cardan joint 10 and the rearward end of wheel hub 20
Attachment washer 30 keep between constant velocity cardan joint 10 and wheel hub 20 it is close and stable be coupled state, this be by Fig. 4 so
Sandwich construction and realize.
As shown in figure 4, form both side surface shape of the ring body in steel substrate 35 of the tabular of the attachment washer 30 of the present invention
Into copper alloy layer 36, and form Teflon layer (teflon layers) 37 on the surface of copper alloy layer 36 and form.
The present invention attachment washer 30 sandwich construction in, steel substrate 35 perform keep attachment washer 30 structure and
The function of form, relatively the copper alloy layer 36 as soft metal realize excellent morphotropism and restoration and cause constant speed ten thousand
To saving close between 10 and wheel hub 20 and being stably close to, Teflon layer 37 also realizes more sensitive morphotropism and restoration,
Uniformly it is close to effect so as to be realized in whole contact surface.
Below, the manufacturing process of the attachment washer 30 of the invention of such sandwich construction is illustrated.
First, copper alloy powder is applied with uniform thickness on the surface of steel substrate 35, then by heating by copper
Sintering alloy powder, so as to form copper alloy layer 36 on the surface of bottom plate 35.
The main material for forming the copper alloy of copper alloy layer 36 is copper (Cu) and tin (Sn), can add a small amount of lead (Pb),
The blending ratio of this copper and tin is preferably 80 weight % to 95 weight % copper and 5 weight % to 20 weight % tin.
In addition, as steel substrate 35, using the copper plated steel for having plated copper on surface in advance, so as to formed it is firmer and
Stable copper alloy layer 36.
After copper alloy layer 36 is formed, Teflon is formed in the surface of copper alloy layer 36 coating Teflon (teflon)
Layer 37, in Teflon layer 37 in addition to Teflon, the additives such as mixed carbon black (carbon black) are gone back, so as to improve
Wear resistance.
After Teflon layer 37 is formed, the multilayer plate body being made up of bottom plate 35, copper alloy layer and Teflon layer 37 is entered
Row is rolled and can be processed into predetermined thickness, and then the multilayer plate body of rolling is realized by punching press (press) processing etc.
Shaping, thus complete the attachment washer 30 of the present invention.
In addition, Fig. 5 and Fig. 6 illustrate the embodiment using supported flexure plate 33, by forming supported flexure plate 33, can save
Slightly above-mentioned protrusion ring body 32, therefore can prevent the outside of the leading section of the foreign steamer 12 to constant velocity cardan joint 10 from forming any dash forward
Go out thing, so as in the absence of feelings to all interference between constant velocity cardan joint 10 and the related miscellaneous part of wheel hub 20
Attachment washer 30 is set under condition.
That is, as shown in figure 5, in the opening portion 31 of attachment washer 30, using the center of attachment washer 30 as axle, put with isogonism
Shape is penetrated formed with multiple protrude inwardly and to the supported flexure plate 33 of the lateral bend of wheel hub 20, as supported flexure plate 33 is clung to
The outer peripheral face of the rearward end of axle 11, attachment washer 30 is fixed with one heart with axle 11, as shown in enlarging section in Fig. 6 circle, be close to
Put into and be formed in rear end of the axle 11 with wheel hub 20 in the terminal part of the supported flexure plate 33 of the outer peripheral face of the rearward end of axle 11
Clearance between side face, the degree of being close to of attachment washer 30 is caused to decline thus without by supported flexure plate 33.
