Description
Technical field
It the utility model is related to piston field, more particularly to a kind of lightweight Split piston.
Background technology
Piston of automobile cans be compared to the central position of automobile engine, for bearing gas pressure, and is driven and connected by piston pin
Bar drives bent axle to rotate, and the part of top land or combustion chamber, account for when engine operates extremely important
Status.
In recent years, because the continuous improvement of engine reinforcing degree, rotating speed, mean effective pressure and the piston of engine are put down
Equal speed all has increased significantly than before, therefore the thermic load of engine and mechanical load both increase.Piston is usual
For monoblock type, it is necessary to integral replacing after damage, but the cost of integral replacing is high, and cost wastes serious, and monoblock type
Piston is difficult to light-weight technologg, and inertia during high-speed cruising is big, and energy consumption is big.
Utility model content
The purpose of this utility model is to provide a kind of lightweight Split piston, reduce overall weight and safeguard into
This.
To use following technical scheme up to this purpose, the utility model：
A kind of lightweight Split piston, including：External jacket and piston core cylinder, the piston core cylinder are arranged concentrically on outside
In sheath, the piston core cylinder bottom indent is provided with cavity, and several losss of weight are arranged at intervals with the outer wall of the piston core cylinder
Groove, the piston core cylinder bottom symmetrical are provided with the pin shaft fixing seat extended to inner side, and the external jacket outer wall bottom is set
There are several loss of weight blind holes, the bolt being connected with piston core cylinder is provided with the loss of weight blind hole.
Wherein, the outer wall of the piston core cylinder and the inwall of external jacket fit.
Wherein, bellmouth is provided with the top of the external jacket endoporus, the piston core cylinder top edge evagination is set
There is conical ring corresponding with bellmouth.
Wherein, compression and oil ring groove are provided with the outer wall of the external jacket.
Wherein, pin shaft hole is horizontally arranged with the pin shaft fixing seat respectively, spring is respectively arranged with the pin shaft hole
Card embedded groove.
Wherein, several loss of weight blind hole annular arrays are distributed on the outer wall of external jacket.
Wherein, the loss of weight blind via bottom is provided with through hole corresponding with bolt, is provided with the piston core cylinder and spiral shell
Screwed hole corresponding to bolt.
The beneficial effects of the utility model：A kind of lightweight Split piston, especially there is provided several lightening grooves and loss of weight are blind
Hole, on the premise of proof strength, overall weight is greatly reduced, is advantageous to the attenuating of motional inertia and the reduction of energy consumption,
Split type structure, installation and removal are easily serviced, and reduce maintenance cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
