Abstract
The utility model discloses a valve tappet assembly, which is composed of a camshaft, a valve, a valve shore and a valve adjusting washer, wherein the valve adjusting washer is arranged at the outside end of the valve shore that is arranged on the valve and is contacted with the camshaft. As the valve adjusting washer is arranged at the outside end of the valve shore, the valve tappet is not necessarily taken down to adjust the valve clearance, quite convenient for actual production and repair; the valve adjusting washer is made larger and is directly contacted with the camshaft so as to increasing the contact area, reduce abrasion, prolong the service life of valve adjusting washer and enable the working performance to be more reliable and the structure to be simpler.
Description
Technical field
The utility model relates to a kind of valve tappet device of engine, especially a kind of lash adjusting device that is used for the valve tappet of motorcycle engine.
Background technique
At present, the direct drive-type of the many employings of most motorcycle Cam-valve Mechanism in High-speed Engine, promptly need not valve rocker, and directly drive valve by camshaft, the valve than other motor that valve is done is thinner, littler, help reducing of valve inertial force, reduce the interference of valve simultaneously, improve intake efficiency air motion.Correspondingly adopt valve list spring structure, can reduce production costs, (as Fig. 1) stablized in the valve clearance.But, pad could be adjusted inconvenience very after when adjusting, valve tappet must being taken off because valve is adjusted the inside that pad is mounted in valve tappet.Simultaneously because valve that the position is limit is adjusted very little that pad does, and the pressure of unit area is just bigger, and when it is heat-treated difficulty reach designing requirement, cause consume comparatively fast.
The model utility content
For solving the shortcoming of above prior art, the utility model provides a kind of valve tappet simple in structure combination, makes the adjustment of valve clearance more convenient, service behaviour is more reliable.
The technical solution adopted in the utility model is, in comprising the valve tappet device that camshaft, valve, valve fore-set, valve adjustment pad are formed, at the outboard end that is installed on laterostigmatal valve fore-set valve is installed and is adjusted pad, this valve is adjusted pad and is contacted with camshaft.For guaranteeing its wear resistance, valve can be adjusted bigger that pad does, increase the area of contact with camshaft, the lubricant oil that enters cylinder head simultaneously is mapped to valve by the direct stream of the oil channel hole of camshaft and adjusts on the pad, reduces its friction, guarantees lubricity.
The outboard end of described valve fore-set can be made groove, and valve is adjusted pad and is installed in this groove.Be the play of anti-air-stop gate spacer sheet, valve is adjusted pad and groove can be fixed with transition fit or with any known method, makes valve adjust pad simultaneously and is higher than groove.
Can also near adjusting the edge of pad, valve make sulculus.Sulculus is used to stir valve and adjusts pad, makes when adjusting the valve clearance more convenient.
The utility model has the advantages that: because valve is adjusted the outboard end that pad is placed on the valve fore-set, do not adjust after valve tappet must not being taken off when adjusting the valve clearance, actual production and maintenance are more convenient; It is big and directly contact with camshaft that valve adjusts that pad does, increased area of contact, reduced wearing and tearing, prolonged the life-span of valve adjustment pad, makes service behaviour more reliable; Simultaneously, simple in structure.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural drawing of prior art scheme.
Fig. 2 is the structural drawing of the valve fore-set of prior art.
Fig. 3 is a structural representation of the present utility model.
Fig. 4 is the structural drawing of valve fore-set of the present utility model.
Fig. 5 is a valve spacer plate shape schematic representation of the present utility model.
Embodiment
At Fig. 1, Fig. 2 is the prior art scheme, wherein camshaft 1, valve fore-set 2, valve adjustments pad 3, and valve adjustments pad 3 is installed in the medial extremity of valve fore-set 2.
In Fig. 3, in the valve tappet device that camshaft 1, valve 4, valve fore-set 2, valve adjustment pad 3 are formed, at the outboard end that is being installed on the valve fore-set 2 on the valve 4 valve to be installed and to be adjusted pad 3, this valve is adjusted pad 3 and is contacted with camshaft 1.For guaranteeing its wear resistance, valve can be adjusted bigger that pad 3 does, increase the area of contact with camshaft 1, the lubricant oil that enters cylinder head simultaneously is mapped to valve by the direct stream of the oil channel hole of camshaft 1 and adjusts on the pad 3, reduces its friction, guarantees lubricity; Referring to Fig. 4, the outboard end of the valve fore-set 2 among Fig. 1 can be made a toroidal cavity 5, valve is adjusted pad 3 and is installed in this groove 5, play for anti-air-stop gate spacer sheet 3, valve is adjusted pad 3 and can be fixed with transition fit or with any known method with groove 5, the thickness that makes valve adjust pad 3 simultaneously is higher than the degree of depth of groove 5, when valve adjustment pad 3 contacts with camshaft 1 like this, valve fore-set 2 can not interfered with camshaft 1, and valve is adjusted pad 3 and also do not had axial moving.Valve adjustment pad 3 is compared with the prior art scheme and has been increased area of contact, reduced the pressure of unit area accordingly, the increase of area helps valve is adjusted the processing on pad 3 planes, control the surface hardness that valve is adjusted pad when heat treatment easily, it is more wear-resisting to make valve adjust pad; Referring to Fig. 5, simultaneously, can also near adjusting pad 3 edges, valve have a sulculus 6, and sulculus 6 is used to stir valve and adjusts pad, changes when being convenient to adjust the valve clearance and adjusts pad, makes when adjusting the valve clearance more convenient.
Claims (3)
1. valve tappet combination, it comprises camshaft, valve, valve fore-set, valve adjustment pad, it is characterized in that: the outboard end that is installed on the valve fore-set (2) on the valve (4) is installed valve adjustment pad (3), and this valve is adjusted pad (3) and contacted with camshaft (1).
2. valve tappet combination according to claim 1 is characterized in that: the outboard end of described valve fore-set (2) fluted (5), valve is adjusted pad (3) and is installed in this groove (5).
