Abstract
The invention discloses an engine timing encloser installation structure which comprises a timing encloser and a cylinder body. The timing encloser is arranged on the cylinder body by a buckling structure. The buckling structure comprises a chuck on the timing encloser, a ball head bolt on the cylinder body and a connecting piece for intermediate transition connection; both ends of the connecting piece are respectively provided with a clamping groove matched with the chuck and a ball head groove matched with the ball head bolt; the timing encloser is clamped with the clamping groove of he connecting piece by the chuck and the cylinder body is connected with the ball head groove on the connecting piece by the ball head bolt so as to implement connection of the timing encloser and the cylinder body. Due to adoption of the buckling connection method, the engine timing encloser installation structure is very convenient to carry out assembling and disassembling operations and has high labor efficiency. Furthermore, to avoid rigid connection of the timing encloser and the cylinder body, a rubber component is used as the connecting piece, so that the resonance risk is reduced and NVH (Noise Vibration and Harshness) quality of an engine can be promoted.
Description
Technical field
The invention belongs to car engine machine technology, be specifically related to the mounting structure of engine timing shell and cylinder block.
Background technique
Engine timing shell is the parts that assemble and protect engine timing train, and timing shell is all generally to adopt 8-10 to be bolted in cylinder block and head now.Fig. 1 is traditional engine timing shell mounting structure, and timing shell 1 is arranged in cylinder block and head by 10 bolts 5.While keeping in repair for timing wheel train, need all construction bolts of dismounting one by one, time-consuming, and need special-purpose instrument, maintenance is poor and maintenance cost is higher.In addition, because timing shell and cylinder block are rigidly connected by bolt, be easy between the two resonate, affect the NVH quality of motor.
Thus, need further to find the improvement project to engine timing shell assembly structure.
Summary of the invention
The above deficiency that the present invention exists over against prior art, object is to provide a kind of engine timing shell mounting structure easy to assemble, and it improves the simplicity of assembling and disassembling section by buckle structure form, efficiency is improved, produce and maintenance man-hours cost; On the other hand by the buckle of the rubber element that adopts, effectively avoid the resonance risk that is rigidly connected and exists, promote motor NVH quality.
Object of the present invention is achieved by the following technical programs:
The engine timing shell mounting structure that the present invention proposes comprises timing shell and cylinder block, and timing shell is arranged in cylinder block by buckle structure.Described buckle structure comprise in dop on timing shell, cylinder block with ball stud and the link connecting by middle transition, described link two ends are respectively equipped with the draw-in groove coordinating with dop and the bulb groove coordinating with ball stud; Timing shell is by the draw-in groove clamping of dop and link, and cylinder block is connected with the bulb groove on link by ball stud, realizes being connected of timing shell and cylinder block.Such buckle connecting means, assembling and disassembling section are all very convenient, and efficiency is high.
Further, for fear of being rigidly connected of timing shell and cylinder block, link is adopted to rubber element, the resonance risk how just to have reduced, can promote motor NVH quality.
In addition, easy to operate object in order to dismantle can also design at least two lugs on the edge of timing shell, during dismounting, with hand or instrument, directly from lug, case is pulled outwardly and can be taken off, simple and efficient to handle.During assembling, by each bulb draw-in groove difference alignment with the ball hook bolt, firmly press.
The present invention has the following advantages:
(1) owing to adopting buckle structure to substitute bolts assemblies mode before, solved timing shell and too much caused the problem of dismounting inconvenience because of construction bolt, the operating procedure of production line assembling and after-sales service is simpler, efficiency raising, saved cost, and easy to implement.
(2) between timing shell and cylinder block, by non-rigid support rubber element, be connected, effectively avoided the resonance risk that is rigidly connected and exists, promoted motor NVH quality.
(3), by the edge designs lug at timing shell, more increase the convenience of assembling.
Accompanying drawing explanation
Fig. 1 is traditional timing shell assembly structure schematic diagram;
Fig. 2 is timing shell assembly structure schematic diagram of the present invention;
Fig. 3 is the sectional view of buckle structure of the present invention.
Embodiment
In order to make those skilled in the art understand better technological scheme, below in conjunction with accompanying drawing, the present invention is further elaborated:
Referring to Fig. 2, be the timing housing mounting structure that the present invention proposes, timing shell 1 is arranged in cylinder block 4 by 10 buckle structures.
Referring to Fig. 3, timing shell 1 adopts the moulding of plastic material Shooting Technique, and when injection moulding, at the inside cavity edge of timing shell 1, forms together 10 T shape dop 1-1.Accordingly, in cylinder block with 10 ball studs 3.Separately have 10 rubber connectors 2 that connect for middle transition, the front end of rubber connector 2 has T shape draw-in groove 2-1, and there is bulb draw-in groove 2-2 rear end.T shape draw-in groove 2-1 phase clamping on T shape dop 1-1 on timing shell and rubber connector, bulb groove 2-2 and the ball stud 3 phase clampings that are arranged in advance in cylinder block 4.
Further the present invention also has the following lower design of optimizing:
The top of T shape dop 1-1 is adopted to fillet design, be beneficial to and press-fit the T shape draw-in groove that enters rubber connector, end adopts right-angle design, guarantees that T shape dop can not deviate from easily from the T shape draw-in groove of rubber connector.
In addition, when selecting the material of rubber connector, consider the rationality of rubber stiffness parameters, simultaneously, while designing the size of bulb groove, consider rational matching allowance, thereby the clamping between bulb groove and ball stud reaches easy to assemble and solid and reliable effect.
Also have, on the edge of timing shell, be also designed with 3 lug 1-2, be convenient to dismounting and assemble with hand or instrument, pull or press constantly.
Assembling and unloading process: first rubber connector is contained on timing shell in advance, ball stud is contained in cylinder block in advance.When being installed, by each bulb draw-in groove difference alignment with the ball hook bolt, firmly presses timing shell; During dismounting, with hand or instrument, directly from lug, case is pulled outwardly and can be taken off
The present embodiment is a kind of specific implementation of the present invention, is not the restriction to this patent, and other on this basis all unsubstantiality changes, as long as this change does not depart from the essence of this patent, within still falling into the protection domain of this patent.
