Camshaft is by frame integrally casting shaping, and after camshaft frame, top valve mechanism cover can use the plastics of lightweight, drop
Low cost mitigates weight simultaneously；But since cylinder head thickness reduces, cylinder head distance from top fire power face is apart from close, camshaft frame
Frame is easy heated.However sealing ring can be set between the cylinder head and camshaft frame of engine, it is therefore an objective to enhancing the two
Between leakproofness to prevent the machine oil of the lubrication in cylinder head and camshaft frame or cylinder head from leaking.But due to cylinder
Light-weighted development is covered, using camshaft frame structure, cylinder head volume reduces, and cylinder head thickness reduces, water channel arrangement space
Reduce, it is difficult to water channel is respectively provided with below each position at the top of the cylinder head, be easy to produce heat aggregation, then sealing ring be easy by
Thermal failure leads to oil leakage.
Summary of the invention
The present invention provides a kind of sealing rings with camshaft frame cooperation to prevent heated flat-top air cylinder head structure, cylinder caping
All machined surfaces in face are in same plane, reduce the height of cylinder head, realize cylinder head loss of weight, are conducive to cylinder head and install
The repair and replacement of component；Inner fovea part is arranged in camshaft frame bottom, makes sealing ring close to water channel, realizes sealing ring good heat radiating,
Concave inward structure improves the structural strength of camshaft frame simultaneously.
Technical scheme is as follows: a kind of anti-heated flat-top cylinder head knot of the sealing ring cooperated with camshaft frame
Structure, including cylinder head, valve mechanism cover, camshaft frame, camshaft-bearing cap, sealing ring and rocker arm bearing housing；The cylinder
All machined surfaces of hd top face are in same plane, the camshaft frame, the camshaft-bearing cap and the rocker arm shaft
Bearing block is all made of aluminum alloy materials of the same race, and the camshaft frame is integrated with camshaft bearing bush seat, the camshaft frame point
Do not connect with the cylinder head and the valve mechanism cover, the camshaft-bearing cap respectively with the camshaft bearing bush seat and described
The connection of rocker arm bearing housing, the camshaft frame side wall are equipped with inner fovea part inwardly, and the inner fovea part is located above exhaust outlet,
Water channel is provided between the inner fovea part and the exhaust outlet；The sealing ring be located at the camshaft frame and cylinder head it
Between, it is installed along the camshaft frame outer profile.Top surface of cylinder cover is designed as plane, cylinder head difficulty of processing is reduced, subtracts
Light cylinder head weight, conducive to the repair and replacement of cylinder head sub-assembly；Camshaft bearing bush seat and cylinder cover split-type design, and realize cam
Aluminum alloy materials can be used in installing component at the top of the cylinder head such as axis frame, camshaft-bearing cap and rocker arm bearing housing, into one
Step reduces engine weight；Camshaft frame indent above the exhaust outlet of cylinder head makes sealing ring avoid directly being vented
It is heated above mouthful；Prevent the sealing ring between cylinder head and camshaft frame because by thermal failure, concave inward structure improves convex simultaneously
The structural strength of wheel shaft frame.
Preferably, the camshaft frame is cast aluminium material, and the valve mechanism cover is plastic material, aluminum camshaft frame
It is advantageously implemented the lightweight of engine, plastic valve mechanism cover advantageously reduces cost and mitigates weight.
Preferably, the camshaft-bearing cap and the rocker arm bearing housing are integrated design, are reduced using integrated design
Assembly process, positioning accuracy is high, saves cost.
Preferably, solid position is equipped with the threaded hole for installing exhaust pipe above the exhaust outlet, and inner fovea part is set
It sets the solid position for solving cylinder head and opens up the heat dissipation problem of sealing ring after threaded hole, be conducive to the cloth of exhaust pipe installation site
It sets.
Preferably, it being fastened by bolts between the valve mechanism cover and the cylinder head, connection is reliable, and it is at low cost, it is convenient for
Disassembly.
Preferably, pass through two positioning finger settings between the camshaft frame and the cylinder head.It is integrated on frame
Camshaft bearing bush seat is reduced positioning pin quantity, is reduced assembly work amount, reduced costs using integrated design structure.
