Abstract
Cylinder mouth gasket is arranged in a kind of cylinder pad of automobile engine between underlying shims and middle layer gasket, and upper layer gasket is arranged on gasket in middle level.There are the dislocation of half of cylinder mouth spacer thickness in cylinder mouth pads placement for upper layer gasket and underlying shims beading, middle layer gasket, allow cylinder mouth gasket on the gasket of middle layer, using the rivet interlacement outside joint surface between each layer of three-decker, structure is smooth between three layers of gasket, every lamellar spacing is small, sealing bar measuring phase is consistent, warping phenomenon does not occur, and sealed precision is high.The sealing bar of upper layer gasket and the sealing bar of underlying shims can form the good band of leakproofness around cylinder mouth.The utility model utilizes the special construction of gasket, rivet interlacement is used between three-decker, save welding link, packaging efficiency can be improved, save the cost, the reduced performance of sealing bar can effectively obstruct high-temperature gas and contact with sealing bar, the durability of sealing bar is improved, is applied in technical field of automobile engine.
Description
Technical field
The utility model relates to one of technical field of automobile engine cylinder pad of automobile engine.
Background technique
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.Cylinder pad of automobile engine is in engine with supercharger gas
Important part, in order to meet the requirement on joint surface between canned motor cylinder body and cylinder cap.In actual use, find with
Lower disadvantage: first is that conventional gaskets are fixed due to being single or multi-layer structure, and by the way of spot welding, gasket surface certainly will be had
Welding slag weldering bits residual, will lead to after gasket compresses and generates gap, cause to reveal；Second is that combustion chamber is held when due to engine operation
By high temperature, high pressure；It is flattened completely third is that conventional gaskets sealing bar under the action of larger bolt power, will lead to sealing bar, it is close
The screen resilience for sealing muscle weakens, and conventional structure gasket seal muscle is directly contacted with high-temperature gas, and high temperature can make the machine of sealing bar
The problem of tool impaired performance, long-time service must will appear leakage.Therefore, a kind of cylinder pad of automobile engine is developed always
It is new issue anxious to be resolved.
Utility model content
The purpose of this utility model is to provide a kind of cylinder pad of automobile engine, the utility model multilayered structure gasket is every
Lamellar spacing is small, connectionless solder joint between each layer gasket, and by periphery tightening of rivet everywhere, gasket surface is smooth, gasket top and bottom
There is fluorine rubber coating, and in the newly-increased circle gasket in cylinder mouth periphery, sealed precision is high, and sealing effect is good, meets canned motor
The requirement of combustion chamber.
Purpose of the utility model is realized as follows: a kind of cylinder pad of automobile engine, including upper layer gasket, middle layer pad
Cylinder mouth gasket is arranged in piece, underlying shims, cylinder mouth gasket between underlying shims and middle layer gasket, in middle level on gasket in setting
Layer gasket；
Middle layer gasket with a thickness of 0.3mm；Upper layer gasket and underlying shims with a thickness of 0.2mm；The thickness of cylinder mouth gasket
For 0.15mm；
Upper layer gasket and underlying shims production material are SUS301；Middle layer gasket production material is SPCC；Cylinder
Mouth gasket material is SUS304.
The utility model is characterized by its structure.Its working principle is that upper layer gasket and underlying shims beading, middle layer
There are the dislocation of half of cylinder mouth spacer thickness in cylinder mouth pads placement for gasket, allow cylinder mouth gasket on the gasket of middle layer, and three
Using the rivet interlacement outside joint surface between layer layers, so structure is smooth between three layers of gasket, every lamellar spacing is small, sealing
Muscle measuring phase is consistent, warping phenomenon does not occur, and sealed precision is high.The sealing bar of upper layer gasket and the sealing bar of underlying shims can
To form a good band of leakproofness around cylinder mouth, the may be implemented using the dislocation and cylinder mouth gasket of middle layer gasket
One band compresses fitting completely, and the sealing bar of Article 2 band is not flattened completely, and upper layer gasket seal can be improved
The resilience performance of muscle and underlying shims sealing bar further increases the sealing performance of sealing bar.Cylinder mouth gasket can avoid High Temperature Gas
Body is directly directly contacted with upper layer gasket with the sealing bar of underlying shims, can effective lift-off seal muscle endurance quality.
A kind of cylinder pad of automobile engine compared with prior art, has a special construction using gasket, three-decker it
Between use rivet interlacement, eliminate welding link, packaging efficiency can be improved, save the cost, in addition the dislocation of middle layer gasket is formed
Annular groove provide positioning for cylinder mouth gasket, improve packaging efficiency, design two bands, effect of the conventional gaskets in bolt power
Under, sealing bar is driven plain completely, according to the compression rebound curve of sealing bar, when sealing bar is flattened completely, the resilience performance of muscle
Being weakened, gasket can effectively avoid sealing bar from being flattened completely using the gap of the structure upper layer and lower layer sealing bar of thickness,
The screen resilience of sealing bar is improved, and then makes to seal relatively reliable, conventional gaskets high-temperature gas is directly contacted with sealing bar, for a long time
Under high temperature action, the reduced performance of sealing bar can effectively obstruct high-temperature gas and contact with sealing bar, improve the durable of sealing bar
It the advantages that property, will be widely used in technical field of automobile engine.
Detailed description of the invention
The utility model is described in detail with reference to the accompanying drawings and embodiments.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Fig. 3 is the installation impaction state schematic diagram of the utility model.
Specific embodiment
Referring to attached drawing, a kind of cylinder pad of automobile engine, including upper layer gasket 1, middle layer gasket 2, underlying shims 3, cylinder mouth
Cylinder mouth gasket 4 is arranged in gasket 4 between underlying shims 3 and middle layer gasket 2, and upper layer gasket 1 is arranged on gasket 2 in middle level.
Middle layer gasket 2 with a thickness of 0.3mm；Upper layer gasket 1 and underlying shims 3 with a thickness of 0.2mm；Cylinder mouth gasket 4
With a thickness of 0.15mm.
Upper layer gasket 1 and 3 production material of underlying shims are SUS301；Gasket 2 production material in middle layer is SPCC；
