Specific embodiment
Embodiment described and illustrated in the disclosure and feature are only preferable example, and its various modifications can also be fallen
Enter in the scope of the present disclosure.
According to an aspect of the invention, there is provided a kind of pre-load member.Fig. 1 is the pre- of embodiment according to the present invention
The plan view of loading component 1.Fig. 2 is the plan view of pre-load member 1 according to another embodiment of the present invention.Pre-load member
1 between the input shaft with external spline teeth and the hub 3 with inner spline gear 31 (see Fig. 4 and Fig. 5) of double mass flywheel 4
Connection.After component 1 is installed to the hub 3 of double mass flywheel 4, when in axis insertion hub 3, power is applied to the input of gear-box
On axis tooth, so that the clearance between hub 3 and axis is removed.Specifically, component 1 has outer periphery ontology 11 and from outer periphery ontology
11 at least one free clearance extended eliminate protruding portion 12.It dashes forward for example, there is the component 1 in Fig. 1 a free clearance to eliminate
Portion 12 out, and there are two free clearance to eliminate protruding portion 12 for the tool of component 1 in Fig. 2.Protruding portion 12 is cut out from centre, so that prominent
Portion 12 is divided into two elongated legs 14 out, and forms empty portion 13.Therefore, leg 14 can be longer and more flexible.When axis is inserted
When entering in hub 3, two 14 clamp shaft teeth of leg allow the applied force on axis tooth of leg 14.That is, two legs 14
Surface contacted with the surface of axis tooth.
Preferred embodiment in accordance with the present invention, the component 1 can have multiple free clearance and eliminate protruding portion 12, so that should
Component 1 has multipair leg 14.When axis is inserted into hub 3, each pair of leg 14 clamps corresponding axis tooth.It is thereby achieved that more preferable
Preloading effect.As shown in Fig. 2, for example, there are two pairs of legs 14 in component 1.Preferably, each pair of leg 14 is roughly the same.
According to an embodiment of the invention, two legs 14 can clamp an axis tooth or multiple axis when in axis insertion hub 3
Tooth, this depends on the density of axis tooth and the quantity and size of leg 14.In the example of fig. 6, two a pair of legs 14 folder
Tight two axis teeth.However, without being limited thereto.As long as two a pair of legs 14 clamp corresponding axis tooth, clearance can be removed,
As long as no matter there are an axis teeth, two between a pair of of leg that is, two a pair of legs 14 clamp corresponding axis tooth
Axis tooth or more than two axis tooth.
Preferred embodiment in accordance with the present invention, component 1 are made of elastomeric spring steel, allow leg 14 in dual quality
The power is kept during the service life of flywheel 4.Therefore, replacement pre-load member 1 is not needed during the service life of double mass flywheel 4.Cause
This, the cost of the component of replacement and personnel's maintenance reduces.
Preferred embodiment in accordance with the present invention can have hub bolt-clearance hole 15 between two adjacent protrusions 12,
So that leg 14 bypasses hub bolt-clearance hole 15, as shown in Figure 2.Therefore, leg 14 can be longer and more flexible.Therefore leg is more
It grows and there is bigger bending radius, so the stress on leg 14 can reduce.
According to another aspect of the present invention, the preloaded components including multiple above-mentioned pre-load members 1 are provided.It is multiple
Pre-load member 1 can be separation, and be respectively installed to hub 3.
Alternatively, multiple pre-load members 1 of preloaded components can be integrally formed, so that preloaded components become
Washer 2 is preloaded, as shown in Figure 3.Fig. 3 is the plan view of the preloading washer 2 of embodiment according to the present invention.With reference to Fig. 3, in advance
At least one the free clearance for loading the outer periphery ontology 11 with annular shape of washer 2 and extending from outer periphery ontology 11 is eliminated
Protruding portion 12.Protruding portion 12 is cut out from centre, so that protruding portion 12 is divided into two elongated legs 14, and forms empty portion 13.
When in axis insertion hub 3, two 14 clamp shaft teeth of leg allow the applied force on axis tooth of leg 14.For example, in Fig. 3
There are washer 2 eight free clearance to eliminate protruding portion 12, so that having eight pairs of legs 14 in washer 2.
It include multiple pre-load members 1 due to preloading washer 2, the features described above of pre-load member 1 can be applied to pre-
It loads in washer 2.
It is the plane that the addition of embodiment according to the present invention preloads the hub 3 of washer 2 referring now to Fig. 4 and Fig. 5, Fig. 4
Figure, Fig. 5 are the cross-sectional views of the hub 3 of the addition preloading washer 2 along the line A-A of Fig. 4 embodiment according to the present invention intercepted.
Hub 3 has the inner spline gear 31 cooperated with the external spline teeth of input shaft (not shown).
Preferred embodiment in accordance with the present invention, free clearance eliminate the circle that protruding portion 12 is distributed generally evenly in washer 2
Zhou Shang is distributed generally evenly in leg to 14 on the circumference of washer 2.Therefore, applied by the leg 14 of washer 2
Power be distributed generally evenly on axis.
In Fig. 4, washer 2 according to the present invention is installed to the side of hub 3.However, without being limited thereto, as long as washer 2 can be with
Fixed on hub 3, then washer 2 can be added to the either side of hub 3 in the axial direction.Preferably due to which the left side of hub 3 is more flat
Smooth (referring to Fig. 5), therefore washer 2 is added to the left side of hub 3, therefore is installed to washer 2 more easily by rivet or bolt
Hub 3.Preferred embodiment in accordance with the present invention, washer 2 is installed to hub 3 by rivet 17, as shown in Fig. 3 to 5.However, being not limited to
This, as long as washer 2 can be fixed to hub 3, washer 2 can be installed to hub 3 by bolt, welding etc..Similarly, preload
Part 1 can be installed to the either side of wheel hub 3 in the axial direction, and can be installed by rivet 17, bolt or welding.This
Outside, it should be noted that pre-load member 1 or the rivet hole 16 for preloading washer 2 are not limited to be positioned according to Fig. 1 to 3.
Fig. 6 be show when pre-load member 1 or preload washer 2 be added to hub 3 when, pre-load member 1 or preload pad
The enlarged view of the relationship of the inner spline gear of the leg 14 and hub 3 of circle 2.As shown in fig. 6, when component 1 or washer 2 are added to hub 3
When, the leg 14 of component 1 or washer 2 and the tooth 31 of hub 3 are Chong Die.In addition, preferred embodiment in accordance with the present invention, is inserted in input shaft
Before entering in hub 3, two a pair of legs 14 are prominent from the profile of the tooth 31 of hub 3 in the opposite direction.Therefore, when axis is inserted into
When in hub 3, the leg 14 of component 1 or washer 2 is bent along the direction far from the contact between leg 14 and axis tooth, so that due to portion
The flexible deformation of the leg 14 of part 1 or washer 2 and apply force on axis tooth.
The leg 14 of preferred embodiment in accordance with the present invention, component 1 or washer 2 has chamfering, to make input shaft and hub 3
Assembly be easier.
Fig. 7 is the plan view of the double mass flywheel 4 of embodiment according to the present invention, wherein preloading washer 2 is added to this
The hub 3 of double mass flywheel 4.Fig. 8 is the transversal of the double mass flywheel 4 along the line A-A of Fig. 7 embodiment according to the present invention intercepted
Face figure, wherein preloading the hub 3 that washer 2 is added to the double mass flywheel 4.Referring now to Figure 8, input shaft will be inserted into from left side
In hub 3, the rotation of hub 3 is allowed to be passed to axis.Due to the preloading washer 2 being installed on hub 3, when in axis insertion hub 3
When, the free clearance between axis and hub 3 is removed, to prevent noise.
Several embodiments are described about pre-load member, but it is to be understood that are not departing from the scope of the present disclosure
In the case where, various modifications can be carried out.Therefore, it will be obvious to those skilled in the art that the disclosure is unlimited
It in described embodiment, but may include appended claims and equivalent.
