Description
Technical field
The utility model relates to motor, particularly relates to a kind of engine cylinder camshaft mounting structure
Background technique
Mounting type between traditional cylinder cap and camshaft adopts " under upper cover seat " form, need first on cylinder cap, to cast out camshaft bearing bush seat, by camshaft-bearing cap camshaft is being fixed on the camshaft bearing bush seat on cylinder cap, this installation form needs the installing space of considering to dodge cylinder bolt when cylinder cap designs, therefore cylinder cap layout design is not compact, and casts and mould all more complicated with the cylinder cap of camshaft bearing bush seat.
Model utility content
The purpose of this utility model is to provide one to make cylinder cover structure simply cast engine cylinder camshaft mounting structure easily.
For achieving the above object, the utility model provides following technological scheme:
A kind of engine cylinder camshaft mounting structure, comprise camshaft bearing bush seat framework and the camshaft-bearing cap of split setting, described camshaft bearing bush seat framework underside face comprises the cam axle mount being arranged on both sides, and described cam axle mount both sides are provided with tapped hole, above the cam axle mount being fixed to camshaft bearing bush seat framework underside face of the bolt left-hand thread that described camshaft-bearing cap passes through, described camshaft is fixedly mounted in cam axle mount by camshaft-bearing cap, the camshaft bearing bush seat framework underside installing camshaft faces down and is sealingly clamped on the cylinder cap of engine cylinder.
As further program of the utility model: described camshaft bearing bush seat framework and camshaft bearing lid form by aluminium squeeze casting.
As further program of the utility model: on described camshaft bearing bush seat framework and cylinder cap, end face is by sealer rigid seal.
As further program of the utility model: described bolt is hexagon flange bolt.
The beneficial effects of the utility model are: described engine cylinder camshaft mounting structure adopts the mounting type of " seat of honour lower cover ", first by camshaft-bearing cap fitted bolt, camshaft is fixed on camshaft bearing bush seat framework underside face, again camshaft bearing bush seat framework underside is faced down on the cylinder cap being fixed to engine cylinder, this mounting type cylinder cap does not need to cast out camshaft bearing bush seat, cylinder cover structure is simple, reduce cylinder cap casting and mould difficulty simultaneously, and end face is high-precision machine and adds face on described camshaft bearing bush seat framework and cylinder cap, and connected by sealer rigid seal, not only do not need to arrange valve cover cap in addition, and reduce the risk of leakage.
Accompanying drawing explanation
The assembling schematic diagram of the engine cylinder camshaft mounting structure that Fig. 1 provides for the utility model;
The structural representation of the engine cylinder camshaft mounting structure that Fig. 2 provides for the utility model.
In figure: 1, camshaft bearing bush seat framework; 11, cam axle mount; 12, tapped hole; 2, camshaft-bearing cap; 3, hexagon flange bolt.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Refer to Fig. 1 to Fig. 2, described engine cylinder camshaft mounting structure, comprise camshaft bearing bush seat framework 1 and the camshaft-bearing cap 2 of split setting, described camshaft bearing bush seat framework 1 and camshaft-bearing cap 2 form by aluminium squeeze casting, described camshaft bearing bush seat framework 1 downside comprises the cam axle mount 11 being arranged on both sides, and described cam axle mount 11 both sides all offer tapped hole 12, above the cam axle mount 11 being fixed to camshaft bearing bush seat framework 1 downside of hexagon flange bolt 3 left-hand thread that described camshaft-bearing cap 2 passes through, described camshaft (not shown in FIG.) is fixedly mounted in cam axle mount 11 by camshaft-bearing cap 2, camshaft bearing bush seat framework 1 downside being provided with camshaft is fixed on the cylinder cap (not shown in FIG.) of engine cylinder downwards, and get up with the cylinder cap rigid seal of sealer by camshaft bearing bush seat framework 1 and engine cylinder.
When described engine cylinder camshaft mounting structure uses, first camshaft is placed in the cam axle mount 11 of described camshaft bearing bush seat framework 1 downside, above the cam axle mount 11 again camshaft-bearing cap 2 being fixed to camshaft bearing bush seat framework 1 downside by hexagon flange bolt 3, camshaft is fixed on camshaft bearing bush seat framework 1 downside, then camshaft bearing bush seat framework 1 downside is fixed to downwards on the cylinder cap of engine cylinder, and get up with sealant sealing, described camshaft bearing bush seat framework 1 is as " seat of honour " of camshaft, described camshaft-bearing cap 2 is as " lower cover " of camshaft, form the mounting type of " seat of honour lower cover ", simplify the structure of cylinder cap, reduce cylinder cap casting and mould difficulty, and fix due to camshaft bearing bush seat framework 1 and cylinder cap rigid seal, can be used as again valve cover cap sealing head valve room, do not need to arrange separately valve cover cap.
Below only with embodiment, the utility model is illustrated, but the utility model is not limited to above-mentioned size and outward appearance illustration, more should form any restriction of the present utility model.As long as any improvement do the utility model or modification all belong within the protection domain of the utility model claim opinion.
