Description
Technical field
This utility model relates to a kind of technical field of mechanical transmission, more specifically, it relates to a kind of Novel rocker arm.
Background technology
Rocking arm in automobile is actually a double-arm lever, and the power being used for transmitting push rod changes direction, acts on valve rod end to push valve open.The ratio of the both sides brachium of rocking arm is referred to as Rocker Ratio, and Rocker Ratio is about 1.2 ~ 1.8, and the most long-armed one end is used to promote valve.The working surface of rocker head is made generally in cylinder, when rocking arm swings can along valve stem end face skid, so can make between the two overcome may be along valve axis effect.Oil leab and oilhole also it is drilled with in rocking arm.In the galianconism end screwed hole of rocking arm, screwing in the adjustment screw in order to valve gap adjustment, the head shoot of screw contacts with the recessed ball seat on push rod top.
At present, the valve rocker on market, it includes valve rocker body.Although this valve rocker body transmission effect is preferable, but because the deficiency in structural strength is easily caused the deformation of valve rocker body, and the friction between bearing and the axis hole in axis hole, easily reduce the valve rocker life-span originally.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of structural strength high, and frictionally damage is little, the Novel rocker arm of life-span length.
nullFor achieving the above object，This utility model provides following technical scheme: a kind of Novel valve rocking arm，Including valve rocker body，Described valve rocker body includes the first main body being provided with axis hole，One end of described first main body is provided with the conflict end for valve stem of conflicting，The other end of the first main body is provided with the force side for transmission，First bracer it is provided with between described conflict end and the first main body，First bracer includes the first side，The cross section straight line of described first side is placed in the tangential direction that axis hole cross section is circular，The junction of described first bracer and conflict end is provided with connection reinforcement district，Connection reinforcement district includes the first connecting portion being sequentially connected with、Rib and the second connecting portion，Rib is placed between the first connecting portion and the second connecting portion，First connecting portion and the first main body are connected with each other，Second connecting portion is connected with each other with conflict end，Described rib is arc-shaped，First connecting portion、Rib and the second connecting portion one connect.
nullBy using technique scheme，Valve rocker body includes the first main body being provided with axis hole，One end of first main body is provided with the conflict end for valve stem of conflicting，The other end of the first main body is provided with the force side for transmission，In order to increase the attachment structure intensity between conflict end and the first main body，First bracer it is provided with between conflict end and the first main body，First bracer includes the first side，The cross section straight line of the first side is placed in the tangential direction that axis hole cross section is circular，Because the longitudinal cross-section of the first side is straight line，The longitudinal cross-section of axis hole is circular，Cross section straight line is in the tangential direction that cross section is circular，The bigger surface stress being allowed to not have during connection reinforcement is poor，Thus ensure that the intensity of attachment structure，In order to increase the first supporter block and the structural strength conflicted between point further，The junction of first bracer and conflict end is provided with connection reinforcement district，Connection reinforcement district includes the first connecting portion being sequentially connected with、Rib and the second connecting portion，Rib is placed between the first connecting portion and the second connecting portion，First connecting portion and the first main body are connected with each other，Second connecting portion is connected with each other with conflict end，Rib is arc-shaped，The concentration that can disperse surface stress of the annexation according to arc structure，Because surface stress excessively concentration can cause weakening of structural strength，So by being placed in the rib between the first connecting portion and the second connecting portion，Be can achieve the effect that it is best，And because the first connecting portion is to be connected with the first main body，Second connecting portion is to be connected with conflict end，The guarantee in structural strength between further ensuring for both，First connecting portion、Rib and the second connecting portion one connect.
This utility model is further arranged to: be additionally provided with the boss of arc-shaped between described conflict end and the first main body, second bracer and the 3rd bracer it is additionally provided with in described first main body, second bracer and the 3rd bracer are respectively placed in boss both sides, and the cross section of second bracer and the 3rd bracer is triangle.
nullBy using technique scheme，The boss of arc-shaped it is additionally provided with between conflict end and the first main body，Had by the boss pair of arc-shaped and conflict end and certain pull power，Because when this body running of rocking arm，Conflict end can be impacted by from different stress points，As time goes on，The deformation of conflict end can be caused，And cause transmission effect to a certain extent，Thus the boss of the arc-shaped increased，The power that conflict end is subject to can be delivered in the first main body，It is allowed to reduce stress，In order to increase the support reinforcing effect for boss further，First main body is provided with second bracer and the 3rd bracer，Second bracer and the 3rd bracer are respectively placed in boss both sides，The cross section of second bracer and the 3rd bracer is triangle，There is the feature of stability according to triangular structure，By second bracer being provided with in the both sides of boss and the 3rd bracer，Add the stress for boss to disperse，And because its longitudinal surface is triangle，Further increase second bracer and the support reinforcing effect of the 3rd bracer.
This utility model is further arranged to: be additionally provided with oil storage tank on described axis hole.
By using technique scheme, oil storage tank it is additionally provided with on axis hole, by the oil storage tank being provided with on axis hole, in the case of installing and using bearing in axis hole, because during bearing rotary, internal with axis hole certain friction can be produced, in order to eliminate the abrasion that this partial frictional causes for bearing or shaft hole inner wall, can be by oil addition in oil storage tank, the problem that just can solve accordingly to exist, can also improve the life-span simultaneously.
This utility model is further arranged to: described axis hole is copper base bearing structure.
By using technique scheme, axis hole is copper base bearing structure, by using copper base bearing structure, further increases the structural strength of axis hole, reduces the abrasion caused for axis hole inside.
