Abstract

The invention discloses a kind of valve actuating push rod, including air valve shaft（1）, in air valve shaft（1）Top sets depression bar（3）, depression bar（3）Front end is installed by roller（2）, roller（3）It is pressed in air valve shaft（1）Top.The original sliding friction of present invention change reduces abrasion into rolling friction, 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

A kind of valve actuating push rod
Technical field
The present invention relates to a kind of air valve structure of engine.
Background technology：
It is direct sliding friction contact between present engine air door-hinge and the cam of camshaft, after usage time has been grown, Wear obvious, and in the presence of frictional force, bring air valve shaft one lateral component, make air valve shaft lateral deviation, aggravate Abrasion between air valve shaft and valve, deforms valve, increases the gap of air valve shaft and valve, influences sealing effectiveness, while Because this gap can also produce abnormal sound when engine works.
The content of the invention：
The technical problem to be solved in the present invention：A kind of air valve structure of rolling friction is provided, has solved existing to start valve The problem of structure is because of the sliding friction abrasion that brings of contact and lateral deviation.
Technical scheme：A kind of valve actuating push rod, including air valve shaft, set depression bar above air valve shaft, before depression bar End installation roller, roller are pressed in the top of air valve shaft.
Preferably, above-mentioned depression bar rotates around installation axle.
Beneficial effects of the present invention：Compared with prior art, air valve shaft of the invention moves in the presence of depression bar, and sets Pressure under roller transmission has been counted, has become original sliding friction as rolling friction, abrasion has been reduced, substantially reduces and be applied to air valve shaft Cross component force, extruding of the air valve shaft to valve is reduced, improves service life.
Brief description of the drawings：
Fig. 1 is schematic structural view of the invention.
Embodiment：
Embodiment：As shown in figure 1, setting a depression bar 3 above air valve shaft 1, depression bar 3 is arranged in installation axle 4, and can be around it Rotate, a roller 2 is installed on the top of depression bar 3, and roller 2 is pressed in the upper surface of air valve shaft 1, when the stress of depression bar 3 moves downward, is led to Cross roller 2 to be pressed downward installation axle 4, while roller 2 rolls 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）Top sets depression bar（3）, depression bar （3）Front end is installed by roller（2）, roller（3）It is pressed in air valve shaft（1）Top.
A kind of 2. valve actuating push rod according to claim 1, it is characterised in that：Depression bar（3）Around installation axle（4）Rotate.
