Description
Technical field
The utility model is related to a kind of cylinder cover of motorcycle engine.
Background technology
The parts such as cylinder body, cylinder cover, camshaft are provided with motorcycle engine, and cylinder cover is fixedly mounted on cylinder body, cam
Axle is movably arranged on cylinder cover, is provided with combustion chamber in cylinder.Due to adopting modular design principle in prior art so that convex
Camshaft stand is needed to be coordinated when wheel shaft is installed on cylinder cover.Camshaft stand is provided with through hole, camshaft during installation
In the through hole, camshaft stand is by screw fixed cylinder lid.Due to the combined mounting structure of camshaft, camshaft
It is indirectly connected between cylinder cover, after Long-Time Service, is easy to generation loosening between camshaft stand and cylinder cover occur, and then
So that camshaft is increased with the frictional force of camshaft stand, the Oscillation Amplitude that camshaft vibration causes engine overall can become to get over
Carrying out bigger, noise increases.
Content of the invention
The technical problems to be solved in the utility model is how to make to be directly connected between camshaft and cylinder cover, thus obtains
A kind of cylinder cover of the motorcycle engine that can keep camshaft reasonable installing position.
For solving above-mentioned technical problem, the utility model is adopted the following technical scheme that：The cylinder cover of the motorcycle engine
Including body, the side of the body is provided with air intake duct and exhaust duct with the combustion chamber of engine, and the body is one
Body formula casting structure, the body opposite side is provided with least two in cylindrical camshaft installing hole and at least four connections are convex
Rise, the center line of the camshaft installing hole overlaps, and wall thickness of the body at camshaft installing hole is more than or equal to camshaft
The diameter of installing hole, the connection bump along camshaft installing hole center line distribution and positioned at camshaft installing hole two
Side, the connection bump are provided with benchmark mounting surface, and the benchmark mounting surface is in same plane.
In the technical program, the structure that can install camshaft on cylinder cover, is provided with, so when camshaft is installed
Directly camshaft can be installed on cylinder cover, so as to avoid camshaft stand is used, thus thoroughly eliminate in prior art
The vibration problem produced because of loosening for existing.Due to the optimization to cylinder head arrangement, it is therefore necessary to consider that cylinder cover will be realized
The function of script, in addition, in addition it is also necessary to impact when heat of the consideration from combustion chamber is worked for camshaft.Because at this
Technical scheme convexity wheel shaft is directly connected to cylinder cover, therefore the path of heat transfer to camshaft is shortened, so must be in cam
Axle and the corresponding radiator structure of position setting that cylinder cover connects, and this structure passes through wall of the body at camshaft installing hole
The thick diameter more than or equal to camshaft installing hole is realizing；Meanwhile, cylinder cover is This structure increases for connecting the portion of camshaft
The mechanical strength of position.
As camshaft is directly connected to cylinder cover so that the overall volume of engine is obviously reduced, therefore in cylinder cover
More space can be vacateed in the position for installing camshaft.In order to make full use of space, and also to cylinder cover can be increased
Heat-sinking capability, be provided with connection bump on cylinder cover.Other parts may be mounted at connection bump and be provided with benchmark mounting surface
Position, meanwhile, connection bump surface increased the area of dissipation of cylinder cover.
Reduce the frictional force between camshaft and cylinder cover, be effectively suppression noise, elongate member service life effective
Means, therefore oil storage passage on the body, is additionally provided with, the oil storage passage end is located at body surface connection, the other end and cam
Axle installing hole is connected.During use, in oil storage passage, lubricating oil is poured into, as lubricating oil is made by own tension in oil storage passage
With and adsorb in oil storage passage, be so easy to lubricating oil to enter the position that camshaft is contacted with cylinder cover at any time.
In order to be able to make full use of the lubricating oil in oil storage passage, it is to avoid remaining a small amount of lubricating oil absorption is in oil storage passage nothing
The situation that method comes into operation, the end that the oil storage passage is connected with camshaft installing hole are straight, and the oil storage passage exists
Its straight end is intersected with camshaft installing hole.So when a small amount of lubricating oil of residue, lubricating oil can be in Action of Gravity Field side
Accumulation effect is upwardly formed, and then whole residue lubricating oil is dragged toward whereabouts.
The utility model adopts technique scheme：The cylinder cover of motorcycle engine is provided with just by optimizing structure
The structure on cylinder cover is directly installed in camshaft.So that the installation relation between camshaft and cylinder cover is maintained, enter
And cause both annexations more firm.
Description of the drawings
With reference to the accompanying drawings and detailed description the utility model is further described in detail.
Fig. 1 is a kind of structural representation of the cylinder cover of motorcycle engine of the utility model.
Specific embodiment
As shown in figure 1, the cylinder cover of the motorcycle engine is integral type casting structure, body 1 is provided with correspondence and starts
The structure of the combustion chamber of the cylinder body of machine and the structure of corresponding camshaft.Specifically, the side of body 1 is provided with the burning with engine
The air intake duct 2 of room connection and exhaust duct 3,1 opposite side of body are provided with two and connect with four in cylindrical camshaft installing hole 4
Raised 5.The center line of two camshaft installing holes 4 overlaps；For improve mechanical strength and heat dispersion, body 1 is in camshaft
Wall thickness at installing hole 4 is equal to the diameter of camshaft installing hole 4.Body 1 is provided with the oil storage passage 7 that quantity is two, each
7 one end of oil storage passage is located at the connection of 1 surface of body, the other end and is connected with a camshaft installing hole 4.During use, lubricating oil is placed in
In oil storage passage 7, in order to improve the service efficiency of lubricating oil, the end that oil storage passage 7 is connected with camshaft installing hole 4 is arranged to
Straight, oil storage passage 7 are intersected with camshaft installing hole 4 at its straight end.Connection bump 5 is along camshaft installing hole 4
Center line distribution and the both sides positioned at camshaft installing hole 4, connection bump 5 is provided with benchmark mounting surface 6, and the benchmark is installed
Face 6 is in same plane.Directly camshaft is placed in camshaft installing hole 4 during use, makes camshaft be directly installed on vapour
On cylinder cap.
