Abstract
The utility model relates to a combined sealing cushion of an engine cylinder cover. The combined sealing cushion consists of an aluminum alloy sealing component and a rubber sealing component, wherein mounting holes fixedly arranged with the engine cylinder cover are formed in the aluminum alloy sealing component at intervals. The combined sealing cushion is characterized in that a flat mounting ring belt is formed on the inner edge of the aluminum alloy sealing component in an extending way; the rubber sealing component is fixedly arranged on the flat mounting ring belt. The sealing cushion is simple in overall structure and scientific and reasonable in design. Due to the fact that the combined sealing form of the aluminum alloy sealing component and the rubber sealing component is adopted, the sealing strength and effect of the engine cylinder cover are effectively enhanced, the engine cylinder cover is prevented from leaking, and the normal running of an engine is guaranteed.
Description
Technical field
The utility model belongs to engine art, relates to sealing cylinder pad, especially a kind of engine cylinder cover combination seal pad.
Background technique
Engine cylinder cover sealing is very important, relates to the normal operation of motor.At present, the sealing of engine cylinder cover only has the end face seal of aluminum alloy, and this metal sealing of aluminum alloy cannot guarantee the lubricating oil leakage of motor, makes thus aluminum alloy sealing be affected.Therefore, strengthening the lubricating oil leakage of engine cylinder cover, is the important guarantee that prevents that engine cylinder cover from leaking.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of engine cylinder cover combination seal pad that can effectively guarantee engine cylinder cover lubricating oil leakage is provided.
The utility model is that technical solution problem adopts following technological scheme:
A kind of engine cylinder cover combination seal pad, by aluminum alloy, sealed and rubber seal forms, in aluminum alloy sealing, interval is shaped with the mounting hole being fixedly mounted with mutually with engine cylinder cover, it is characterized in that: the inner edge extension in aluminum alloy sealing is shaped with flat installation endless belt, on this installation endless belt, is fixed with rubber seal.
And described rubber seal is double sealing.
Advantage of the present utility model and good effect are:
1, this sealing gasket adopts the combination seal form of aluminum alloy sealing and rubber seal, has effectively strengthened sealing intensity and the effect of engine cylinder cover, has avoided the leakage of engine cylinder cover, has guaranteed the normal operation of motor.
2, this sealing gasket adopts setting-in mode to be connected aluminum alloy sealing and rubber seal, connects reliably, and integrality is good, can effectively avoid departing from.
3, this sealing gasket overall structure is simple, and design science is reasonable.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cross section cutaway view Amplified image.
Embodiment
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail, it should be noted that, the present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.
An engine cylinder cover combination seal pad, consists of aluminum alloy sealing 1 and rubber seal 3, and the shape of aluminum alloy sealing is identical with the contour shape of engine cylinder cover, and in aluminum alloy sealing, interval is shaped with the mounting hole 2 being fixedly mounted with mutually with engine cylinder cover.
Innovative point of the present utility model is:
Inner edge extension in aluminum alloy sealing is shaped with flat installation endless belt 4, on this installation endless belt, is fixed with rubber seal.
In the present embodiment accompanying drawing, shown rubber seal is double sealing, to improve the radial expansion performance of rubber seal, strengthens sealing effect.
Claims (2)
