Description
Technical field
The utility model is related to a kind of vehicle engine booster entrance pads in technical field of automobile engine.
Background technology
Currently, with the promotion of people's living standard, automobile has become staple commodities and has entered into huge numbers of families.And internal vapor
Expanding increasingly for vehicle production capacity keeps the competition between major whole-car firm more and more fierce.Under such market environment, automobile
Performance boost, cost control fall over each other focus of attention at manufacturer.Vehicle engine booster entrance pad is that supercharging is started
Important part in machine gas, in order to meet the requirement of canned motor exhaust manifold and booster interface.It was actually using
Cheng Zhong has found following disadvantage：First, conventional gaskets are due to being multilayered structure, and fixed by the way of spot welding, gasket surface gesture
There must be welding slag weldering bits residual, generate gap after gasket can be caused to compress, cause to reveal；Second is that since interface bolt is arranged by item
Part limits, and is unevenly distributed so that sealed muscle measuring phase is inconsistent, warping phenomenon occurs；Third, conventional gaskets sealed muscle exists
Under the action of larger bolt power, sealed muscle can be caused to be flattened completely, the screen resilience of sealed muscle weakens, and conventional structure gasket
Sealed muscle is in direct contact with high-temperature gas, and high temperature can be such that the mechanical performance of sealed muscle weakens, and long-time service must will appear leakage
The problem of, therefore a kind of vehicle engine booster entrance pad of research and development is always new issue anxious to be resolved.
Utility model content
The purpose of this utility model is to provide a kind of vehicle engine booster entrance pad, the utility model multilayered structures
Gasket is small per lamellar spacing, and connectionless solder joint between each layer gasket is fastened by flange, and gasket surface is smooth, and gasket is without special painting
Layer, manufacture craft is simple, and sealed precision is high, and sealing effect is good, meets canned motor exhaust manifold and booster interface
It is required that.
What the purpose of this utility model was realized in：A kind of vehicle engine booster entrance pad, including upper layer gasket,
Middle level gasket is arranged in middle level gasket, underlying shims on underlying shims, upper layer gasket is arranged on gasket in middle level, and upper layer is padded
Piece is contacted with underlying shims, domed muscle on the gasket of middle level, the arc-shaped turnup structure in upper layer gasket left part；
A kind of upper layer spacer thickness of vehicle engine booster entrance pad is 0.3mm；Middle level gasket and lower layer
Spacer thickness is 0.25mm；The arc-shaped turnup structure flanging length 2mm in upper layer gasket gas port end, middle level gasket arch muscle are a height of
0.3mm；In free state, the lower plane of upper layer gasket and the upper plan range of middle level gasket are 0.3mm, exhaust manifold method
Blue B lower planes are 1.1mm with plan range on booster flange C；In impaction state, lower plane and the middle level of upper layer gasket are padded
The upper plan range of piece is 0.05mm, air discharging manifold flange B lower planes and the upper plan ranges of booster flange C for for
0.85mm；
The upper layer gasket and underlying shims production material of a kind of vehicle engine booster entrance pad be
SUS304；Middle level gasket production material is SUS301.
The utility model is characterized by its structure.Its operation principle is：Upper layer gasket design at gas port be in arc
Shape turnup structure, middle level gasket beading, underlying shims are natural shaped, and compressing no-welding-spot using flange between each layer of three-decker connects
It connects, so structure is smooth between three layers of gasket, small per lamellar spacing, sealed muscle measuring phase is consistent, warping phenomenon, gasket does not occur
Without specific coatings, manufacture craft is simple, and sealed precision is high.Turning over for upper layer gasket can be formed all over structure and the convex ribs of middle level gasket
Two good bands of leakproofness may be implemented first band using the thickness difference of three layers of gasket and compress fitting completely,
And the convex ribs of Article 2 band are not flattened completely, and the resilience performance of middle level gasket seal muscle can be improved, to further carry
The sealing performance of high sealing muscle.It is directly direct with the sealed muscle of middle level gasket that the turnup structure of upper layer gasket can avoid high-temperature gas
Contact, can effective lift-off seal muscle endurance quality.
A kind of vehicle engine booster entrance pad compared with prior art, has a special construction using gasket, three layers
No-welding-spot connection is compressed using flange between structure, welding link is eliminated, packaging efficiency can be improved, cost-effective, another flange
The flatness and cleannes on surface can be improved in press fitting connection, and sealed precision is high, and sealing effect is good, and two bands are in conventional gaskets
Under the action of bolt power, sealed muscle is driven plain completely, when being flattened completely according to the compression rebound curve-seal muscle of sealed muscle,
The resilience performance of muscle is weakened, and uses thickness for the upper layer gasket of 0.3mm, and using the structure turned over time, can effectively be avoided
The sealed muscle of middle level gasket is flattened completely, improves the screen resilience of sealed muscle, and then keeps sealing relatively reliable, conventional gaskets high temperature
Gas is in direct contact with sealed muscle, and under long-term high temperature action, the performance of sealed muscle substantially reduces, and turnup structure can effectively hinder
The advantages that being contacted with sealed muscle every high-temperature gas, improving the durability of sealed muscle will be widely used in automobile engine technology
In field.
