Abstract
The invention relates to a transport safety device (1, 2) for a dual clutch (10), characterized in that the transport safety device (10) consists of a composite material that can be dissolved in a coolant.
Description
Technical field
The present invention relates to a kind of double clutch with transportation insurance device.
Background technology
Come for a long time, from the double clutch known in the art with transportation insurance device.
In the double clutch that wet type is run, relieving ring is installed on the clutch as transportation insurance device.Relieving ring exists
There is the function of transportation insurance, whereby, lid and friction disc support do not lift from pressurized tank in the state of installation.Once clutch
It is fixedly fitted in clutch cap, the defunctionalization of ring.The ring is not retained in clutch functionally.
Due to radially accelerated, can in experiments it is found that：Transportation insurance ring on the clutch is moved in its groove, and
It can be jumped out when adversely bumping against on anti-rotation lock from the groove.In the case of most harmless, the ring is located at clutch with releasing
In device cover and produce significantly can be from the noise that hear of outside.In the worst case, the ring can clutch rotation
Component and static component between warpage and hinder the function of clutch.
The content of the invention
Accordingly, there exist the technical assignment for overcoming the shortcoming from prior art.
According to ground of the invention, the task is solved particularly by the transportation insurance device for double clutch, wherein, it is described
Transportation insurance device is made up of the composite that may be dissolved in cooling agent.
By setting transportation insurance device, as its presence is also abolished in the failure of the function of ring.
The present invention relates to all transportation insurance devices being contemplated that.When double clutch is run, pass through the cold of radial inflow
But agent continues forcefully to water the transportation insurance device.
It is preferred that cooling agent is oil, especially cooling oil or transmission oil.Dissolving is preferably understood that transportation insurance device
Loss of strength.Transportation insurance device preferably dissolves in this way：The transportation insurance device lose its intensity, hardness and/
Or static bearing capacity.Preferably, transportation insurance device dissociates, crushes or be dissolved into its part.It is particularly preferred that
Chemically reacted to realize the dissolving of transportation insurance device.
According to the embodiment of the present invention, the composite that may be dissolved in cooling agent is laminate.
Laminate is the material that cost is cheap and can be dissolved in easily in cooling agent.
Materials described below or product are preferably referred to as laminate：The material or product are by two or more face formulas ground phase
Mutually coherent layer is constituted.These layers can be made up of identical or different material.
According to the embodiment of the present invention, the composite that may be dissolved in cooling agent have at least one plastics and
Organic material.
Organic material is cost advantages and the material that can be readily dissolved in cooling agent.
It is preferred that the organic material does not produce the change of the characteristic of cooling agent after its dissolving.
According to the embodiment of the present invention, the organic material is fibrous composite or the material with cellulose
Material.
Fibrous composite is preferably made up of usual two kinds of principal components, especially embedding basic unit and the fiber of reinforcing
Heterogeneous material or mixing material.Due to the interaction of two kinds of components, this material obtains what is individually participated in than two kinds
The characteristic of the higher quality of each in component.
Material with cellulose is preferably plant or plant part, paper or timber.
According to the embodiment of the present invention, transportation insurance device is configured to open relieving ring.
Open ring is preferably not closed ring.The ring preferably has opening, and the opening interrupts the annular of closure
Shape.
According to the embodiment of the present invention, relieving ring has at least
- one recess,
- one specified weakened segment and/or
The cross section of-one partly constriction.
Implement decomposition of the relieving ring in cooling agent with can speed up whereby.It is contemplated that multiple volumes preferably inside ring
Determine weakened segment, the specified weakened segment causes defined course of dissolution.
According to the embodiment of the present invention, the recess or specified weakened segment are arranged in the shell surface of inside, outside
In at least one in the shell surface in portion and/or in two sides of relieving ring.
Whereby there is provided a variety of possibilities：Weaken the cross section of relieving ring, to accelerate point of the relieving ring in cooling agent
Solution.
In addition, according to the present invention, the task is particularly by the double clutch solution with least one transportation insurance device
Certainly.
Each friction disk clutch is preferably provided with a transportation insurance device.
Double clutch is preferably the double clutch of wet type, in the double clutch of the wet type, in order to insure clutch
Pressurized tank, insert the transportation insurance device in insurance loop type, the relieving ring no longer needs in clutch start.Because fortune
Defeated safeties are made up of the composite in the cooling agent that may be dissolved in double clutch, two transportation insurance devices due to it is cold
But agent is contacted and dissolved.Here, cooling agent chemically reacts with organic material, the organic material dissolving.
Brief description of the drawings
Now, the present invention is exemplarily illustrated by accompanying drawing.It illustrates：
Fig. 1 according to the present invention transport ring schematical view, and
Fig. 2 passes through the schematical section of double clutch with transport ring and from Fig. 1, according to the present invention.
Embodiment
Relieving ring is configured to according to Fig. 2 transportation insurance device 1,2.The relieving ring has opening 3, and the opening interrupts closure
Ring-shaped.The relieving ring meets the function of transportation insurance in mounted situation.The relieving ring has multiple recesses 5.Recess 5
Arrange in the shell surface 4 of inside of relieving ring.
Transportation insurance device 1,2 is made up of composite, and the composite may be dissolved in cooling agent.It may be dissolved in cold
But the composite in agent has plastics and organic material.For example it is used as organic material using paper.
When being contacted with cooling agent, transportation insurance device 1,2 gradually dissolves, and the cooling agent is used for cold in double clutch
But.On the one hand, because the setting of organic material.Here, cooling agent chemically reacts with organic material, organic material
Material dissolving.On the other hand, by setting recess 5 additionally to accelerate course of dissolution, because the cross section of transportation insurance device 1,2 subtracts
It is small.
Fig. 2 double clutch 10 according to the present invention has the transport ring 1,2 according to Fig. 1.In addition, double clutch 10 has
Lid 11, the first inner attrition piece support 12, the first outside friction disc support 13, the first friction plate group 14 and first pressure tank 15.This
Outside, double clutch 10 has the second inner attrition piece support 16, the second outside friction disc support 17, the second friction plate group 18 and second
Pressurized tank 19.
In addition, setting separator 20, the separator is provided for shifting pressurized tank 6,11.In addition, should not be in detail
The action principle of double clutch is inquired into, because the action principle is from known in the art.
Transportation insurance device 1,2 has the function of insurance.Lid 11 and friction disc support 12,13,16,17 should not in assembling
It can lift from pressurized tank 6,11.Once double clutch 10 (being not shown) is installed, is fixedly fitted in clutch cap, transport
The function of defeated safeties 1,2 just disappears.
Because transportation insurance device 1,2 is made up of the composite in the cooling agent that may be dissolved in double clutch 10, two
Transportation insurance device 1,2 dissolves due to being contacted with cooling agent.
