Description
Technical field
The present invention relates to the moving seesaw-type rocker arms (Kipphebel) or pendulum-type rocker arm of a kind of valve transmission device for internal combustion engine
(Schwinghebel), on lower edge, first longitudinal direction end have at least one scavenging air valve contact surface with
And with the transverse holes for being supported on axis in the section between its lateral middle and second longitudinal direction end, wherein for
For rocker arm, the cam rolling surface of upper edge is intrinsic.
Background technique
Rocker arm is learnt by Fig. 3 of attached drawing according to prior art.The rocker arm is casting pendulum-type rocker arm, and is arranged and is used for 1
Internal combustion engine (autocycle, motorcycle, spare motor, the garden furniture motor of cylinder or the small size of 2 cylinder technologies
Deng) valve transmission device in.Alternative is constructed in casting, and the rocker arm being forged is also used for the internal combustion engine of small size above-mentioned.
Furthermore previously known with bending ram technology by the U of sheet material structure or the rocker arm of H-shaped.
All design schemes result in it and relatively high cost and manufacture when necessary excessively heavy in batch production.Afterwards
Person improves valve transmission acting.Can also occur structure space exactly in the rocker arm of the U or H-shaped that manufacture with bending ram technology to ask
Topic.
Summary of the invention
The task of the present invention is the rocker arms created as mentioning as before, can especially be manufactured inexpensively and simply fill
Match, and only needs seldom structure space.
According to the present invention, which solves as follows, that is, rocker arm, wherein moving seesaw-type rocker arm is also allowed for, by plate
Formed, and either a) be made of the plate of one vertical (aufrecht) otherwise b) by it is multiple wall side mutually recline vertically
Plate is constituted, wherein the cam rolling surface of rocker arm and its contact surface for being directed to scavenging air valve are formed with the width at respective edge.
Particularly preferred improvement project according to the present invention, in situation a), plate is generated by accurate cutting, and in feelings
In condition b), plate is manufactured by punching press pile (Stanzpaketieren), and is connected with each other.However it is also recognized that and setting
It is, in the case where multiple vertical plates, these plates of accurate cutting, and it is connected with each other under vertical state.
Therefore there are valve transmission device rocker arms, no longer have the shortcomings that be initially mentioned in the valve transmission device rocker arm.It will
The valve transmission device of the internal combustion engine of small size is considered as preferably using field, as it is for example constructed in the case where two wheeler
As.As an alternative, the pump piston of such as fuel charge can also be loaded by the rocker arm proposed, or rocker arm can be made to construct
Within the compressor.
Of the invention is particularly characterized in, the contact surface and cam rolling surface on rocker arm are not specially constructed and add
It is wide.The border width of at least one plate is finally only provided.This advantageously reduces manufacturing cost.
The face mentioned before can be by (critically) polishing, and is furnished with wear-resistant layer.For example expect herein with PVD or
The hard material layer of CVD method coating.When necessary, these faces can also be heat-treated.
Improvement project according to the present invention, new-type rocker arm are completely flat, that is, without bending.This can reduce its packet
Size is filled, and is further conducive to simplify.
Another materialization scheme according to the present invention is provided that, in the case where multiple vertical plates, these plates are kept
It is mutually the same.Therefore a kind of tool set is only needed.Special geometry can also be generated by the plate differently cut when necessary
Shape.
In the case where the assembly of the multiple plates described before, these plates can also be combined with each other by different materials, from
And the good compromise between workpiece performance (such as rigid) and cost for example can be obtained.
In order to carry out the connection of plate pile, protrusion-hole or pin-hole design scheme are proposed.Alternative is extraly also examined
Consider rivet interlacement or is bolted.Likewise it is possible to melting welding, stickup, be brazed or be similarly machined.
The invention further relates to the two methods for manufacturing rocker arm.On the one hand, which can be with accurate cutting method, by plate
Material or lath generate.On the other hand expect：Punching press pile is carried out at least two boards.Especially clean section structure is obtained herein
At.It does not need or only needs to reprocess to a small extent.
Detailed description of the invention
The present invention is learnt by following attached drawing：
Fig. 1 shows the side view of pendulum-type rocker arm；
Fig. 2 shows the longitudinal sections for passing through the pendulum-type rocker arm in pile frame mode；
Fig. 3 shows the pendulum-type rocker arm according to prior art casting construction.
Specific embodiment
Fig. 1 discloses the pendulum-type rocker arm H made of steel plate with side view.The pendulum-type rocker arm is by vertical and flat plate
1 is constituted, which is manufactured by fine-edge blanking.
On lower edge 4, the contact surface 6 for scavenging air valve is shown at first longitudinal direction end 5.In second longitudinal direction end 8
Place, rocker arm H has transverse holes 9, be supported on rocker arm on axis.Oilhole 13 is directed across rocker arm H from transverse holes 9.
On the top edge of rocker arm H 10, cam rolling surface 11 is formed between lateral middle 7 and first longitudinal direction end 5.It is convex
Wheel rolling surface and contact surface 6 do not shape individually, and substantially with the width at respective edge 10,4.Cam rolling surface and
The wear-resistant layer that contact surface is covered with equipped with painting, wherein polishing processing is occurring before.
Fig. 2 shows the rocker arm H formed by two vertical plates 2,3 with cross-sectional view.Plate 2,3 is manufactured by punching press pile,
And it is fixed to each other by protrusion-hole-interconnecting piece 12.In other aspects, plate is identical to each other.Sightless face 6,10 is same
Sample does not shape individually, and the width substantially with plate pile 2,3 and the wear-resistant layer mentioned again.
By Fig. 3, learn according to the prior art in the diagram of space with rocker arm H1 made of casting technique (pendulum-type rocker arm).
