Colloid, rubber bodies fixed sleeves is provided with overcoat, and rubber bodies is connected by binding agent is fixing with outer inner room, and overcoat is elastic tubular knot
Structure, on the sidewall of elastic tubular structure, opening forms energy circumference dilatation tubular structure, overcoat, rubber bodies, interior axle vertically
Overlap the most fixedly sleeved formation automobile differential lining overall structure.
The automobile differential lining that the present invention improves uses the overcoat of open design, improves the endurance quality of product, tool
There is process cost low, the feature that NVH performance is excellent.
Accompanying drawing explanation
Fig. 1 is the schematic front view of this programme automobile differential lining.
Fig. 2 is the cross-sectional schematic of automobile differential lining.
Fig. 3 is the section view close-up schematic view of a kind of implementation of overcoat.
Wherein, 100 is overcoat, and 200 is rubber bodies, and 300 is internal axle sleeve, and 210 is tubular plastic liner, and 220 is through hole knot
Structure, 310 is keyway arrangements, and 110 is eaves in clamping, and 120 is gap, and 130 is to compress to fasten.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Fig. 1～2, the schematic diagram of automobile differential lining of the present invention.Outside the automobile differential lining improved includes
Set, rubber bodies, internal axle sleeve, internal axle sleeve fixed sleeves is provided with rubber bodies, and rubber bodies fixed sleeves is provided with overcoat, rubber bodies and overcoat
Between connect by binding agent is fixing, overcoat is elastic tubular structure, and on the sidewall of elastic tubular structure, opening forms energy vertically
Circumference dilatation tubular structure, overcoat, rubber bodies, internal axle sleeve the most fixedly sleeved formation automobile differential lining
Overall structure.Such scheme uses the design of open loop jacket structure, uses the product of new construction not only to substantially increase the resistance to of self
Performance for a long time, and equally meet the Dynamic and static stiffness requirement of client, and decrease process cost.
In order to improve the integrally-built performance of differential mechanism lining, this programme has also carried out entering one on the basis of such scheme
Step is improved.The structural strength combined for reinforcing member, it is ensured that integrally-built stability, this programme is in rubber bodies is set in
Being provided with tubular plastic liner in ring core internal layer on axle sleeve, tubular plastic liner is set on internal axle sleeve by rubber bodies, thus
Improve the coupling stiffness of rubber bodies.In order to improve the overall vibration damping of lining, anti-acoustic capability, this programme is at the outer edge of rubber bodies
Circumferentially arranged with the through-hole structure of the most through some extensions in Ceng, above-mentioned through-hole structure alleviates the vibration that internal axle sleeve produces,
As it is shown in figure 1, this programme is the most equidistantly provided with the through-hole structure of 4 extensions the most through.In order to ensure transmission
Stability, this programme is provided with keyway arrangements on the medial wall of internal axle sleeve vertically, and the inner side of keyway arrangements is globoidal structure, from
And improve the efficiency of assembling and improve stress distribution.In order to improve the stability that overcoat is combined with rubber bodies, this programme exists
The two ends of overcoat are provided with eaves in clamping, and in clamping, eaves fastener is located on the outer edge of rubber bodies, thus prevent both axles
To relative motion.In order to improve the performance of structure itself, the material of the preferred internal axle sleeve of this programme is rustless steel, preferably the material of overcoat
Matter is aluminium alloy.
The open loop jacket structure design that the automobile differential lining of this programme uses can be realized by following two mode.
Embodiment one
Relate in such scheme can circumference dilatation tubular structure be elastic opening circular bent plate structure, and elasticity is opened
It is provided with gap between mouthful circular bent plate structure one end circumferentially and the elastic opening circular bent plate structure other end circumferentially,
By controlling the radial dimension of the width dimensions regulation overcoat in above-mentioned gap.As it is shown in figure 1, such scheme is at closed loop overcoat
Offer opening on side, thus can well alleviate overcoat irregular with what rubber bodies produced when by external compression
Deformation, is changed into the Bending Deformation of circumference, reduces the probability that the binding agent between overcoat and rubber bodies destroys, enhances product
Endurance quality.
Embodiment two
Relate in such scheme can circumference dilatation tubular structure be elastic opening circular bent plate structure, and elasticity is opened
Circumferentially arranged with some wedge shapes projection, the circular song of elastic opening on the lateral surface of mouth circular bent plate structure one end circumferentially
Circumferentially arranged with some wedge-shaped impressions on the medial surface of the plate structure other end circumferentially, wedge shape is protruding and wedge-shaped impression is in elasticity
Formed under the elastic force effect of open circles ring-type bent plate structure to compress and fasten, protruding and above-mentioned some by adjusting above-mentioned some wedge shapes
The radial dimension of the mated condition regulation overcoat of wedge-shaped impression.As shown in Figure 3, although be also open loop structure, but this programme is kept away
Exempt from the gap structure of opening, preferably protected the internal structure of lining, it is also possible to avoid the overcoat compressed deformation to unclamp.
The automobile differential lining of this programme realizes being greatly improved of durability of product energy by changing product jacket designs,
Optimizing NVH performance, overcome the rubber bushing of traditional structural design to produce the hidden danger of defect, it is outer sheathed that this programme have employed open loop
Meter, the product of new construction not only substantially increases durability of product energy, and the Dynamic and static stiffness equally meeting client is wanted
Ask, and decrease process cost, thus increase customer satisfaction degree, reduce the generation of customer complaint probability.Use this new design
Lining can reduce undergauge operation, and product is when being pressed into pilot hole, and the variant of overcoat is bending rather than internal
Intermolecular mutual extruding, reduces the destruction probability of binding agent the most to a certain extent, thus improves bond effect, Jin Erzeng
The strong endurance quality of product.Based on above feature, the automobile differential lining of this programme is compared existing product and is had prominent
Substantive distinguishing features and significantly progressive.
The automobile differential lining of this programme is not limited to the content disclosed in detailed description of the invention, occurs in embodiment
Technical scheme can be with individualism, it is also possible to mutually comprise, and those skilled in the art combine common knowledge according to this programme and make
Simple alternative fall within the scope of this programme.
