Abstract
The utility model relates to a diesel engine air door bridge, especially an air door bridge applied in the four diesel engine, including a platform therebetween, also grooves arranged on the two ends symmetrically. The diesel engine air door bridge of the utility model has the platform and the grooved on the two ends symmetrically, wherein two grooves are sleeved in the air door, thereby the outside control can control the two inlet valves or the discharge valve simultaneously.
Description
(1) technical field
The utility model relates to a kind of diesel engine spiracle bridge, especially is applied to the air valve bridge of four-valve diesel engine.
(2) background technique
The carrying capacity of current vehicle improves day by day, requires the diesel engine output power constantly to increase, and along with adding of Abgasgesetz is tight, the emission from vehicles standard also improves constantly.For reaching these requirements, the four-valve diesel engine of two intake valves of every cylinder and two exhaust valve structures substitutes original intake valve of every cylinder and two valve diesel of an exhaust valve structure gradually, becomes development of diesel trend from now on.Original two valve diesel are to control the keying of each valve separately, and are simple in structure, and control also is easy to; If but each valve of four-valve diesel engine controls separately, not only control difficulty, and also the correlated parts structure Design can be very complicated, and also very high to spatial requirement.
(3) summary of the invention
The utility model provides a kind of diesel engine spiracle bridge in order to overcome the deficiency of above technology.
The utility model is by the following technical solutions:
This model utility diesel engine spiracle bridge comprises the platform that is positioned at its middle position, also comprises being positioned at the symmetrically arranged groove in its two ends.
Above-mentioned diesel engine spiracle bridge, one of described groove are circular, and another is a round end flat key flute profile.If also have other device to act on air valve bridge, a groove top is provided with boss therein, and this groove is the single round end flat key of an open type flute profile, and another groove is circular, and platform left and right sides two-part quality equates.Above-mentioned diesel engine spiracle bridge, described groove top is provided with the lubricant oil oilhole.
The utility model diesel engine spiracle bridge comprises platform and be positioned at the symmetrically arranged groove in its two ends, and two grooves are inserted in valve respectively, and external control can be controlled two intake valves or exhaust valve simultaneously by platform like this.One of described groove is circular, another one is a round end flat key flute profile, this structure not only can solve because the installation question that the total tolerance of two valve spacings is brought, also can solve valve and air valve bridge in the operation process because the interference problem that thermal expansion produces, also avoid air valve bridge simultaneously because allow deviation range excessive and cause the problem that comes off easily.If there is other device to act on air valve bridge, can be by on air valve bridge, increasing a boss, this device acts on this boss and realizes.The groove design that increases a side of boss is the open type structure, in order to offset the weight that boss increased.The lubricant oil that enters by groove top oilhole is used for lubricated and the cooling air raft of pontoons and valve lap.

(5) embodiment
Embodiment 1:
With reference to Figure of description 1 and 2, this model utility diesel engine spiracle bridge comprises the platform 3 that is positioned at its middle position, also comprises being positioned at the symmetrically arranged groove 1 in its two ends.1 one of described grooves are circular, and another is a round end flat key flute profile, and groove 1 top is provided with lubricant oil oilhole 2.Platform 3 left and right sides two-part quality equate.External control is by platform 3 control air valve bridges, and two grooves 1 are inserted in valve respectively, and external control can be controlled two intake valves or exhaust valve simultaneously by platform 3 like this.1 one of described grooves are circular, another one is a round end flat key flute profile, this structure not only can solve because the installation question that the total tolerance of two valve spacings is brought, also can solve valve and air valve bridge in the operation process because the interference problem that thermal expansion produces, also avoid air valve bridge simultaneously because allow deviation range excessive and cause the problem that comes off easily.The lubricant oil that enters by groove top oilhole is used for lubricated and the cooling air raft of pontoons and valve lap.
Embodiment 2:
With reference to Figure of description 3 and 4, this model utility diesel engine spiracle bridge comprises the platform 3 that is positioned at its middle position, also comprises being positioned at the symmetrically arranged groove 1 in its two ends.1 one of described grooves are circular, and another is single round end flat key flute profile, and groove 1 top is provided with lubricant oil oilhole 2, is provided with boss 4 on single round end flat key slotted recess 1 top, and should list round end flat key slotted recess 1 be the open type structure.External control is by platform 3 control air valve bridges, and two grooves 1 are inserted in valve respectively, and external control can be controlled two intake valves or exhaust valve simultaneously by platform 3 like this.1 one of described grooves are circular, another one is single round end flat key flute profile, this structure not only can solve because the installation question that the total tolerance of two valve spacings is brought, also can solve valve and air valve bridge in the operation process because the interference problem that thermal expansion produces, also avoid air valve bridge simultaneously because allow deviation range excessive and cause the problem that comes off easily.Be provided with boss 4 on single round end flat key slotted recess 1 top, can introduce other control, and should list round end flat key slotted recess 1 be the open type structure, guarantee that platform 3 left and right sides two-part quality equate.The lubricant oil that enters by groove top oilhole 2 is used for lubricated and the cooling air raft of pontoons and valve lap.
