Abstract
Engine timing shell mounting structure proposed by the present invention, it includes timing shell and cylinder block, and timing shell is arranged in cylinder block by buckle structure.The buckle structure includes the dop on timing shell, the ball stud of band and the connector connected with middle transition in cylinder block, and the connector two ends are respectively equipped with the neck coordinated with dop and the bulb groove coordinated with ball stud；Timing shell is connected by the neck clamping of dop and connector, cylinder block by ball stud with the bulb groove on connector, realizes the connection of timing shell and cylinder block.Such to snap connection method, assembly or disassembly operation is all very convenient, and efficiency is high.Further, being rigidly connected in order to avoid timing shell and cylinder block, uses rubber element, the resonance risk how to be reduced by can lift engine NVH quality by connector.
Description
Technical field
The invention belongs to automobile engine technology, and in particular to engine timing shell and the mounting structure of cylinder block.
Background technology
Engine timing shell is the part for assembling and protecting engine timing train, and present timing shell is typically all to adopt
It is bolted to 8-10 in cylinder block and head.Fig. 1 is traditional engine timing shell mounting structure, timing cover
Shell 1 is arranged in cylinder block and head by 10 bolts 5., it is necessary to dismount one by one all when being repaired for timing wheel train
Installation bolt, it is time-consuming, and special instrument is needed, maintainability is poor and maintenance cost is higher.Further, since timing shell
It is rigidly connected with cylinder block by bolt, is easy to resonate between the two, influences the NVH quality of engine.
Thus, it is desirable to further find the improvement project to engine timing shell assembling structure.
The content of the invention
It is not enough above that the present invention just exists to prior art, it is therefore intended that provides a kind of engine timing shell easy to assemble
Mounting structure, it improves the simplicity of assembly or disassembly operation by buckle structure form so that efficiency is improved, production
With the reduction of maintenance man-hours cost；On the other hand by using rubber element buckle, be prevented effectively from being total to for the presence that is rigidly connected
Shake risk, lift engine NVH quality.
The purpose of the present invention is achieved by the following technical programs：
Engine timing shell mounting structure proposed by the present invention includes timing shell and cylinder block, and timing shell passes through card
Buckle structure is arranged in cylinder block.The buckle structure include dop on timing shell, the ball stud of band in cylinder block, with
And the connector connected with middle transition, the connector two ends are respectively equipped with the neck and and ball stud coordinated with dop
The bulb groove of cooperation；Timing shell passes through ball stud and connector by the neck clamping of dop and connector, cylinder block
On bulb groove connection, realize the connection of timing shell and cylinder block.It is such to snap connection method, assembly or disassembly operation
All easily, efficiency is high.
Further, how just being rigidly connected in order to avoid timing shell and cylinder block, use rubber element, by connector
The resonance risk reduced, can lift engine NVH quality.
In addition, purpose easy to operate during in order to dismantle, can also design at least two convex on the edge of timing shell
Ear, case during dismounting be directly pulled outwardly and can removed at lug with hand or instrument, simple and efficient to handle.By each ball during assembling
Head neck is respectively aligned to ball stud, firmly presses.
The present invention has advantages below：
（1）Due to the bolts assemblies mode before instead of using buckle structure, timing shell is solved because of installation bolt
The operating procedure of the problem of excessively causing to dismount inconvenience, production line assembling and after-sales service is simpler, and efficiency is improved, and is saved
Cost, and it is easy to implement.
（2）It is attached between timing shell and cylinder block by non-rigid support rubber element, effectively prevent rigidity
The resonance risk existed is connected, engine NVH quality is improved.
（3）By the edge designs lug in timing shell, more increase the convenience of assembling.
Brief description of the drawings

Fig. 2 is timing shell assembling structure schematic diagram of the invention；
Fig. 3 is the sectional view of the buckle structure of the present invention.
Embodiment
In order that those skilled in the art more fully understands technical scheme, further is made to the present invention below in conjunction with the accompanying drawings
Elaborate：
It is timing housing mounting structure proposed by the present invention referring to Fig. 2, timing shell 1 is pacified by 10 buckle structures
In cylinder block 4.
Referring to Fig. 3, timing shell 1 is using the shaping of plastic material Shooting Technique, and the cavity in injection in timing shell 1
Internal edge forms 10 T-shaped dop 1-1 together.Accordingly, with 10 ball studs 3 in cylinder block.Separately there are 10
There is T-shaped neck 2-1 the rubber connector 2 connected for middle transition, the front end of rubber connector 2, and there is bulb neck 2- rear end
2.T-shaped dop 1-1 on timing shell and the T-shaped neck 2-1 phase clampings on rubber connector, bulb groove 2-2 and peace in advance
The phase clamping of ball stud 3 in cylinder block 4.3-1 is the bulb of ball stud.
Further the present invention also has the design of following lower optimization：
T-shaped dop 1-1 top is used into fillet design, beneficial to the T-shaped neck press-fited into rubber connector, end is adopted
With right-angle design, it is ensured that T-shaped dop can not be deviate from from the T-shaped neck of rubber connector easily.
In addition, when selecting the material of rubber connector, the reasonability of rubber stiffness parameter is considered, meanwhile, design
During the size of bulb groove, rational matching allowance is considered, so that the clamping between bulb groove and ball stud reaches
Effect easy to assemble and solid and reliable.
Further, 3 lug 1-2 are also devised with the edge of timing shell, hand or work are constantly used in easy to disassemble and assembling
Tool is pulled or pressed.
Assembly or disassembly process：First rubber connector is mounted on timing shell in advance, ball stud is mounted in cylinder block in advance
On.Each bulb neck is respectively aligned to ball stud when timing shell is installed, firmly pressed；Hand or instrument are straight during dismounting
Connect at lug and case is pulled outwardly and can removed
The present embodiment is a specific embodiment of the present invention, is not the limitation to this patent, it is other it is all
Unsubstantiality on the basis of this changes, as long as this essence changed without departing from this patent, still falls within the protection of this patent
Within the scope of.
