Background
Currently, the application of the turbo-charging technology is wide, and an actuator (such as an EGR valve, a supercharger bypass valve and the like) on an engine, a brake of the whole vehicle and the like need a negative pressure power source, so that a vacuum pump needs to be added, wherein a mechanical vacuum pump is the most commonly used scheme. The vacuum pump is driven to work through the cam shaft. The vacuum pump is usually arranged between the cylinder cover and the cylinder cover, and the cylinder cover are sealed by adopting plane gluing or sealing rings.
However, the sealing ring is adopted between the cylinder cover and the cylinder cover, so that the scheme of integrating the cam bearing cover on the cylinder cover is not suitable, and a sealing ring is required to be added, so that the cost of parts is increased;
glue coating and sealing are adopted: the requirement on the processing plane of the combination surface of the cylinder cover and the cylinder cover is high, and oil seepage is easy to occur when the glue coating is uneven and discontinuous; in addition, the peripheral sealing area of the vacuum pump, namely the combination surface of the cylinder cover and the cylinder head cover, is continuously impacted by lubricating oil to the sealing surface when the vacuum pump is operated, and oil seepage occurs in the area.
Disclosure of Invention
In order to ensure the sealing of the periphery of a vacuum pump or the joint area of the whole cylinder cover body and the cylinder cover, the invention provides the cylinder cover with the increased glue storage groove structure.
The invention adopts the following technical scheme to realize the purposes:
the utility model provides an increase cylinder cap of storing up gluey groove structure, includes the cylinder cap body and seals the cylinder cap cover on the cylinder cap body through the rubber coating, this internal cavity that is equipped with of cylinder cap, the cylinder cap body is close to the one end of cylinder cap cover and is equipped with the storing up gluey groove, storing up gluey groove intercommunication the cavity.
Preferably, the glue storage groove is provided in a circular, semicircular, rectangular, trapezoidal or V-shape.
Preferably, the cylinder cover body is provided with a vacuum pump, and the vacuum pump comprises a vacuum pump input shaft and a vacuum pump housing covering the vacuum pump input shaft.
Preferably, the glue storage groove extends from the joint surface of the vacuum pump housing and the cylinder cover body into the cavity of the cylinder cover body.
Preferably, the cylinder cover body is provided with a mounting groove, and the vacuum pump housing is mounted on the cylinder cover body through the mounting groove.
The beneficial effects of the invention are as follows:
according to the cylinder cover with the rubber storage groove structure, the rubber storage groove is designed at one end, close to the cylinder cover, of the cylinder cover body, so that lubricating oil permeated through the joint of the cylinder cover body and the cylinder cover can not pass through the sealing strip when the vacuum pump operates, and then flows back into the cavity of the cylinder cover body, the rubber storage groove can contain certain sealant to form a uniform continuous sealing strip, engine oil impact during operation of the vacuum pump can be effectively solved, sealing of the periphery of the vacuum pump or the joint area of the whole cylinder cover body and the cylinder cover is ensured, oil permeation caused by part processing, gluing and other problems is avoided, and meanwhile cost increase is reduced as much as possible. In addition, the design of the glue storage groove has relatively low glue coating requirements and processing requirements on the joint surface of the cylinder cover body and the cylinder cover, and can be realized only by a machining mode without changing a die, so that the change cost is low.

fig. 2 is a perspective view of a cylinder cover with a glue storage groove structure according to an embodiment of the present invention;
fig. 3 is a perspective view of a cylinder cover with an additional glue reservoir structure according to an embodiment of the present invention.
In the figure, the combination part of the cylinder cover body and the cylinder cover is 1-cylinder cover body, 2-cylinder cover, 3-glue storage groove, 4-vacuum pump, 5-vacuum pump input shaft, 6-vacuum pump shell, 7-cylinder cover body.
Detailed Description
The invention will now be described in detail with reference to figures 1-3 and the detailed description.
Referring to fig. 1 to 3, the present embodiment provides a cylinder cover with an increased glue storage groove structure, including a cylinder cover body 1 and a cylinder cover 2 sealed on the cylinder cover body 1 by glue, a cavity is disposed in the cylinder cover body 1, one end of the cylinder cover body 1, which is close to the cylinder cover 2, is provided with a glue storage groove 3, and the glue storage groove 3 is communicated with the cavity.
When the cylinder cover with the rubber storage groove structure is used, permeated lubricating oil cannot directly flow into the rubber storage groove 3 through the sealing strip, and then flows back into the cavity of the cylinder cover body 1. The glue storage groove 3 can contain certain sealant to form a uniform continuous sealing strip, so that the sealing of the joint 7 area of the whole cylinder cover body and the cylinder cover is ensured, oil seepage caused by the problems of part processing, gluing and the like is avoided, and meanwhile, the cost increase is reduced as much as possible. In addition, the design of the glue storage groove 3 has relatively low glue coating requirements and processing requirements on the joint surface of the cylinder cover body 1 and the cylinder cover 2, and can be realized only by a machining mode without changing a die, so that the change cost is low.
As a preferable mode of this embodiment, the glue storage groove 3 is formed in a circular, semicircular, rectangular, trapezoid or V-shape, mainly after gluing, glue can enter the glue storage groove 3, so that a sealing strip constructed by a proper amount of sealing glue is formed at the joint 7 of the cylinder cover body and the cylinder cover. The specific size of the glue storage tank 3 can be designed according to the structure of the sealing belt.
As one preferable example of the present embodiment, the vacuum pump 4 is mounted on the side of the cylinder head body 1 near the cylinder head cover 2, and the vacuum pump 4 includes a vacuum pump input shaft 5 and a vacuum pump housing 6 that encloses the vacuum pump input shaft 5. In the present embodiment, an installation groove is provided on one side of the cylinder head body 1, and the vacuum pump housing 6 is installed on the cylinder head body 1 through the installation groove. The vacuum pump input shaft 5 is driven to work through a cam shaft of the engine, so that a negative pressure power source is provided for the whole vehicle brake.
As a preferable mode of this embodiment, the glue storage tank 3 extends from the joint surface of the vacuum pump housing 6 and the cylinder head body 1 into the cavity of the cylinder head body 1, so that the lubricating oil that has permeated through the joint 7 between the cylinder head body and the cylinder head cover during the operation of the vacuum pump 4 cannot pass through the sealing strip, and then flows back into the cavity of the cylinder head body 1 from the glue storage tank 3, thereby effectively solving the engine oil impact during the operation of the vacuum pump and ensuring the sealing of the joint region of the whole cylinder head body 1 and the cylinder head cover 2.
While the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the invention and are intended to be within the scope of the invention as claimed.
