Abstract
The utility model discloses a kind of valve actuating push rods, including air valve shaft（1）, it is characterised in that：In air valve shaft（1）Compression bar is arranged in top（3）, compression bar（3）Front end is installed by idler wheel（2）, idler wheel（3）It is pressed in air valve shaft（1）Top.The utility model becomes original sliding friction as rolling friction, reduces abrasion, substantially reduces the cross component force for being applied to air valve shaft, reduces extruding of the air valve shaft to valve, improves service life.
Description
Technical field
The utility model is related to a kind of air valve structures of engine.
Background technology：
It is direct sliding friction contact between present engine air door-hinge and the cam of camshaft, usage time has grown it
Afterwards, abrasion is obvious, and under the action of frictional force, brings air valve shaft one lateral component, make air valve shaft lateral deviation, add
Abrasion between acute air valve shaft and valve, makes valve deform, and increases the gap of air valve shaft and valve, influences sealing effect, simultaneously
When the engine is working since this gap also will produce abnormal sound.
Utility model content：
The technical problems to be solved in the utility model：A kind of air valve structure of rolling friction is provided, has been solved existing
The problem of starting air valve structure to contact the abrasion brought and lateral deviation because of sliding friction.
The technical solution of the utility model：Compression bar is arranged in a kind of valve actuating push rod, including air valve shaft above air valve shaft, pressure
Idler wheel is installed in bar front end, and idler wheel is pressed in the top of air valve shaft.
Preferably, above-mentioned compression bar is rotated around installation axle.
The beneficial effects of the utility model：
Air valve shaft moves under the action of compression bar, and devises idler wheel and transmit lower pressure, and the sliding friction for becoming original is to roll
Dynamic friction reduces abrasion, substantially reduces the cross component force for being applied to air valve shaft, reduces extruding of the air valve shaft to valve, and raising makes
Use the service life.
Description of the drawings：
FIG. 1 is a schematic structural view of the utility model.
Specific implementation mode：
Such as Fig. 1, a compression bar 3 is set above air valve shaft 1, compression bar 3 is mounted in installation axle 4, and can be rotated around it, and is pressed
An idler wheel 2 is installed on 3 top of bar, and idler wheel 2 is pressed in the upper surface of air valve shaft 1, when 3 stress of compression bar moves downward, passes through idler wheel 2
Installation axle 4 is pressed downward, while idler wheel 2 is rolled in the upper surface of air valve shaft 1.
Claims (2)
1. a kind of valve actuating push rod, including air valve shaft（1）, it is characterised in that：In air valve shaft（1）Compression bar is arranged in top（3）, compression bar
（3）Front end is installed by idler wheel（2）, idler wheel is pressed in air valve shaft（1）Top.
2. a kind of valve actuating push rod according to claim 1, it is characterised in that：Compression bar（3）Around installation axle（4）Rotation.
