The angle at tip is slided between 60 °~20 ° in tip and described second.
Preferably, described first slide tip and described second slide tip surface be coated with erosion resistant coating.
Preferably, described first slide tip and described second slide tip the anti-corrosion layer surface be coated with it is wear-resisting
Layer.
Preferably, described first slide tip and described second slide tip inside be equipped with inner cavity, the lumen loading
There is sound-absorbing sponge.
Force transmitting board provided by the utility model slides tip and by be diagonally arranged on force transmitting board ontology first
Two slide the unequal setting of angle at tip, so, when the force transmitting board ontology under sliding state is mutually hit with spring,
Due to first slide tip with second slide tip angle it is different, it is different from the contact area of spring, thus collision frequency
The shock sound of difference, generation is also different, it is possible thereby to reduce impact noise significantly, solves the problems, such as that knocking noise is excessive.
The utility model also provides a kind of double mass flywheel, including force transmitting board, and the force transmitting board is specially any of the above-described
The force transmitting board, due to above-mentioned force transmitting board, so that the NVH performance of double mass flywheel is significantly improved.
The utility model also provides a kind of car transmissions, including double mass flywheel, and the double mass flywheel is specially
Double mass flywheel described in any of the above embodiments.The car transmissions stable drive, noise are small.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment

It is the embodiments of the present invention, for those of ordinary skill in the art, without creative efforts, also
Other attached drawings can be obtained according to the attached drawing of offer.Fig. 1 is the structural schematic diagram of force transmitting board provided by the utility model；
Fig. 2 is the structural schematic diagram of double mass flywheel provided by the utility model.
Wherein, 1- force transmitting board ontology, 11- first slides tip, 12- second slides tip, 2- spring.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
In order to make those skilled in the art more fully understand the utility model, with reference to the accompanying drawing and specifically
The utility model is described in further detail for embodiment.
Referring to FIG. 1, Fig. 1 is the structural schematic diagram of force transmitting board provided by the utility model.
The utility model provides a kind of force transmitting board, including force transmitting board ontology 1, and force transmitting board ontology 1 is set there are four contact jaw,
When being in coast period due to automobile, the torque of force transmitting board ontology 1 is big, and first in diagonal position as shown in Figure 1 slides
Tip 11 and second slides tip 12 and constantly hits spring 2 and generate noise, in order to reduce impact noise, slides point for first
The angle design at end 11 is unequal at the angle for sliding tip 12 with second, and first slides tip 11 and second and slide tip
12 be acute angle, that is to say, that first slides tip 11 and second to slide tip 12 be horn structure, and the angle of sharp corner is equal
For acute angle, and angle is not mutually equal, so, when automobile is in coasting mode, the first of diagonal angle on force transmitting board ontology 1
It sliding tip 11 and first and slides tip 12 when contacting simultaneously with spring 2, the wedge angle angle for sliding tip due to two is different,
Then different from the contact area of spring 2, the frequency noise of sending is also different, while reducing knocking noise, promotes double quality and flies
The vehicle NVH characteristic and durability of wheel.
Specifically, the angle that the first angle for sliding tip 11 slides tip 12 less than second, it is preferred that first slides
Tip 11 and second slide tip 12 angle be set to 60 °~20 ° between, for example, first slide tip 11 angle be 30 °,
Second angle for sliding tip 12 is 60 °, slides tip 11 and second using spring 2 and first and slides the contact area at tip 12
Thus difference reduces knocking noise.
Tip 11 and second can also be slided first and slide the surface anticorrosive coating at tip 12, to prevent corrosive liquid
Body corrodes, and improves first and slides tip 11 and second while slide the corrosion resistance at tip 12, prolongs its service life.
Tip 11 and second is slided in order to further increase first and slides the service life at tip 12, it can be in erosion resistant coating
Surface applies coating rubbing-layer, such as ceramic wearing coat, slides tip 11 and second with raising first and slides the surface quality at tip 12.
In order to further decrease the knocking noise of force transmitting board ontology 1 Yu spring 2, tip 11 and second can be slided first
Slide tip 12 inside filling sound-absorbing sponge, first slide tip 11 and second slide tip 12 inside be equipped with inner cavity, it is interior
Sound-absorbing sponge is filled in chamber, can not only mitigate weight, moreover, can play using the excellent sound-absorbing effect of sound-absorbing sponge
Absorb the effect of knocking noise.It is of course also possible to first slide tip 11 and second slide tip 12 outer peripheral surface cladding every
Sound-proof material is attached to first by adhesive agents such as glue and slides tip 11 and second and slide the surface at tip 12, to keep away by sound cotton
Exempt from knocking noise.
The utility model also provides a kind of double mass flywheel, as shown in Fig. 2, including above-mentioned force transmitting board, due to above-mentioned
Force transmitting board, therefore, under coasting mode, the NVH characteristic of the double mass flywheel is significantly improved.
The utility model also provides a kind of car transmissions, including above-mentioned double mass flywheel, due to above-mentioned double matter
Flywheel is measured, so that the stable drive of the car transmissions, and noise is small.
It should be noted that in the present specification, such as first and second etc relational terms are used merely to one
Entity is distinguished with other several entities, and without necessarily requiring or implying between these entities, there are any this actual
Relationship or sequence.
Detailed Jie has been carried out to car transmissions provided by the utility model and double mass flywheel and force transmitting board above
It continues.Specific case used herein is expounded the principles of the present invention and embodiment, and above embodiments are said
The bright method and its core concept for being merely used to help understand the utility model.It should be pointed out that for the common of the art
