Frame is connect with cylinder cap ontology and cylinder head cover respectively up and down, camshaft-bearing cap respectively with camshaft bearing bush seat and rocker arm axle bearing
Seat connection；The camshaft frame side wall is equipped with inner fovea part inwardly, and inner fovea part is located above exhaust duct, inner fovea part and exhaust duct
Between be provided with water channel；The sealing ring is pacified between camshaft frame and cylinder cap ontology along camshaft frame outer profile
Dress.In the utility model, sealing ring and exhaust duct are separated by water channel, so that sealing ring be made to avoid exhaust duct, and have water channel
Cooling, aging and failing aggravates caused by avoiding sealing ring and being influenced because the heat by exhaust duct.
Preferably, the camshaft frame is cast aluminium material, and the cylinder head cover is plastic material；Using aluminum camshaft frame
Frame is advantageously implemented the lightweight of engine, and plastic cylinder head cover advantageously reduces cost and mitigates weight.
Preferably, the camshaft-bearing cap and the rocker arm bearing housing are integrated design；Simplified using integrated design
Assembly technology improves assembly precision, reduces cost.
Preferably, it is fastened by bolts, is bolted between the cylinder head cover and the cylinder cap ontology, connection jail
It leans on, is also easy to remove and repair.
Preferably, by two positioning finger settings between the camshaft frame and the cylinder cap ontology, in camshaft frame
Cam bearing pedestal is integrated on frame, using integrated design structure, is reduced positioning pin quantity, is reduced assembly work amount, reduce
Cost.
The beneficial effects of the utility model are:
1, in the utility model, inner fovea part is set in camshaft frame side wall, sealing ring is arranged along camshaft frame, is passed through
Water channel separates sealing ring and exhaust duct, so that sealing ring be made to avoid exhaust duct, and has water channel cooling, avoid sealing ring because by
Aging caused by heat influence to exhaust duct and failure aggravation.
2, in the utility model, cylinder head cover uses light-weighted plastic material, and camshaft frame uses aluminium alloy material mass-energy
The overall weight for enough mitigating cylinder cover structure, realizes lightweight.
3, in the utility model, camshaft frame and camshaft bearing bush seat integrated design, camshaft-bearing cap and rocker arm shaft
Bearing block integrated design, facilitates the raising of assembly precision, simplifies assembly technology.
