Piston of automobile cans be compared to the central position of automobile engine, and extremely important status is accounted in engine start.
In recent years, due to the continuous improvement of engine reinforcing degree, revolving speed, mean effective pressure and the mean piston speed of engine are all
It has increased significantly than before, therefore the thermic load of engine and mechanical load both increase.And piston is due to starting
Important function in machine, designing and manufacturing aspect, there has also been very big change and raisings, are just able to satisfy society height in this way
It is required that discharge standard.
The fixation hole of fixed pin shaft is usually provided in piston, pin shaft utilizes Spring Card progress pin shaft after being inserted into fixation hole
The installation and removal of the limit at both ends, Spring Card are comparatively laborious, and the fragile structure of Spring Card is easy the damage in disassembly, bullet
The installation of spring card is not suitable for the built-up piston of separate structure yet.Integrally-built piston maintenance cost is high, the dimension of built-up piston
Installation at low cost, but being detrimental to pin shaft is protected, it is cumbersome, affect the convenience of assembling and maintenance.
Utility model content
The purpose of this utility model is to provide a kind of pin shafts to install convenient Split piston, promotes the convenience of pin shaft installation
Property, reduce maintenance cost.
For this purpose, the utility model uses following technical scheme:
A kind of pin shaft installs convenient Split piston, comprising: bolt, first piston cylinder, second piston cylinder, lid and
The top of second piston cylinder is arranged in pin shaft, the first piston cylinder, and the lid is arranged concentrically on first piston cylinder
Top, be symmetrically arranged with two connecting rods for extending to second piston cylinder inboard wall bottom on the first piston cylinder inboard wall,
The pin shaft is horizontally installed in second piston cylinder and both ends extend through corresponding connecting rod, the second piston cylinder outer circle
On be provided with the stepped hole for being directed toward connecting rod, the bolt is arranged in stepped hole and is connected with connecting rod.
Wherein, be disposed with from top to bottom in the second piston cylinder outer circle first gas ring slot, second gas ring slot and
Oil ring groove.
Wherein, the first piston cylinder body bottom is provided with a circle bulge loop, is provided with one at the top of the second piston cylinder
Enclose groove corresponding with bulge loop.
Wherein, the connecting rod, lid and first piston cylinder are integrated aluminium alloy structure.
Wherein, through-hole corresponding with pin shaft is provided on the connecting rod.
Wherein, threaded hole corresponding with bolt is provided on the connecting rod.
The utility model has the beneficial effects that a kind of pin shaft installs convenient Split piston, pin shaft is mounted on second piston cylinder
In vivo, and using the through-hole on connecting rod it is limited, assembling convenience, is consolidated after connecting rod insertion second piston cylinder using bolt
It is fixed, sound construction, dismantle it is also more convenient, can fission safeguarded, reduce maintenance cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The technical solution of the utility model is further illustrated below with reference to Fig. 1 and by specific embodiment.

The pin shaft 10 is horizontally installed in second piston cylinder 3 and both ends extend through corresponding connecting rod 12, and installation is just
Benefit is not necessarily to Spring Card, stable structure.
The stepped hole 8 for being directed toward connecting rod 12 is provided in 3 outer circle of second piston cylinder, the bolt 9 is arranged in ladder
It is connected in hole 8 and with connecting rod 12, improves the structural stability of connecting rod 12, mounts and dismounts all more convenient.
In the present embodiment, it is disposed with first gas ring slot 7, second from top to bottom in 3 outer circle of second piston cylinder
Compression 4 and oil ring groove 5, first gas ring slot 7, second gas ring slot 4 facilitate the installation for carrying out compression ring respectively, and oil ring groove 5 carries out oil
The installation of ring.
In the present embodiment, 2 bottom of first piston cylinder is provided with a circle bulge loop 6,3 top of second piston cylinder
It is provided with circle groove corresponding with bulge loop 6.The cooperation of bulge loop 6 and groove improves first piston cylinder 2 and second piston cylinder
The cooperation progress of body 3, air-tightness are good.
In the present embodiment, the connecting rod 12, lid 1 and first piston cylinder 2 are integrated aluminium alloy structure, structure jail
Gu light-weight.
In the present embodiment, through-hole corresponding with pin shaft 10 is provided on the connecting rod 12, facilitate pin shaft 10 installation and
Positioning.
In the present embodiment, it is provided with threaded hole 11 corresponding with bolt 9 on the connecting rod 12, facilitates the installation of bolt 9
And disassembly, can fission safeguarded, reduce maintenance cost.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
