Abstract
The utility model discloses a four properties door engine valve is passed a bridge convenient to assembly, valve pass a bridge and are equipped with two valve stem mounting holes, and first is rectangular hole, and the one end in this rectangular hole is semi -circular, and one end is the opening in addition, a second mounting hole is circular to regard as the locating hole with the second mounting hole. The top that the valve was passed a bridge is a plane, and the rocking arm is through the contact of passing a bridge of this plane and valve. Two valve stem mounting holes all are equipped with lubricated oil duct, and two valves are installed respectively in two valve stem mounting holes. Through shaking in the lubricated machine oil that splashes gets into the valve stem mounting hole, provide lubricated between passing a bridge for valve stem head gentleness door in the brachial cell. Two valve mounting holes designs of passing a bridge the valve are the rectangular hole of open -ended semicircle, can be very easily during the assembly install the mounting hole that the valve passed a bridge with two valve stem heads in. Otherwise because the fit clearance is little, adjust two valve stems entering mounting holes simultaneously well wastes time and energy very much, and can obviously improve assembly efficiency through above measure.
Description
Technical field
This utility model belongs to engine fittings and in particular to a kind of valve bridge structure being applied to electromotor.
Background technology
Countries in the world require more and more strictly to the standard of engine exhaust emission and oil consumption at present, with Europe exhaust method
Rule have become as low emission, the basic structure of low oil consumption in Europe execution, four-valve engine.Many valveizations of electromotor are permissible
Increase power per liter, improve dynamic property and susceptiveness and improve rate of fuel consumption simultaneously, be to reduce one of effective measures of exhaust pollution.Four
Valve refers to that the valve number of every cylinder is four, two inlet valves, two exhaust valves.Using Four valve structure engine inlet and outlet
Sectional area increases, and comparing Four valve air inlet area with two valves can increase by 30% about, and leaving area about increases by 50%.In addition
Two inlet valves improve mixed Daqu, it is possible to decrease the discharge capacity of co and hc, because combustion duration shortens, thus decrease
The formation of nox.Increased using charging efficiency after Four valve, burning velocity increases, improve charging efficiency and improve engine speed
Result make engine power export to increase up to 45%, power per liter is also improved.Four-valve engine generally adopts gas
The structure that door is passed a bridge controls the switch of two inlet valves or exhaust valve to realize rocking arm simultaneously.Pass a bridge and valve to reduce valve
The abrasion of bar and vibration, valve is passed a bridge with valve stem head using less fit clearance assembling.Less fit clearance is in assembling
When, relatively difficult if two valve stem heads are inserted simultaneously into the installing hole that valve is passed a bridge if ensured.In order to improve efficiency of assembling,
The utility model proposes four-valve engine valve pass a bridge it is ensured that valve stem head smoothly insert valve pass a bridge install
Hole.
Content of the invention
The purpose of this utility model is to propose a kind of valve bridge structure be easy to and assemble and keep in repair, and can protect in assembling
Card valve stem head smoothly inserts valve gap bridge installing hole, improves efficiency.
It is to be easy to the four-valve engine valve assembling to realize this purpose technical solution adopted in the utility model
Pass a bridge and include: valve gap bridge, rocking arm and valve.Valve is passed a bridge and is provided with two valve stem installing holes, first valve stem installing hole
For strip hole, one end of this strip hole is semicircle, and the other end of strip hole is opening；Second valve stem installing hole is circle
Shape, and using duaspiracle bar installing hole as location hole.The top that valve is passed a bridge is a plane, and rocking arm passes through this plane and gas
Door is passed a bridge and is contacted.Two valve stem installing holes are equipped with oil leab, and two valves are respectively arranged in two valve stem installing holes
Interior.Valve stem is entered by the lubricating oil of rocking arm interior splashing in the hole is installed, be to carry between the gentle door of valve stem head is passed a bridge
For lubrication.
Its principle is: the tip designs of gap bridge are the plane contacting with rocking arm, and rocking arm, by the contact with plane, controls two
The gap that individual valve is passed a bridge with valve is mated.It is strip hole that key is one of two valve stem installing holes, is so accurately to tear open
Dress provides great convenience, and the installation positioning that valve is passed a bridge only is carried out by another one valve stem installing hole.Simultaneously in order to protect
The lubrication that card valve stem head is passed a bridge with valve, each valve stem installing hole devises oil leab, the indoor splashing profit of rocking arm
Sliding machine oil can enter into valve stem by oil duct and install in the hole, provides lubrication between passing a bridge for the gentle door of valve stem head
Machine oil, reduces the friction that engine valve is passed a bridge with valve stem, it is to avoid serious wear.
The beneficial effect of feature of the present utility model and generation is: two valve installing holes that valve is passed a bridge are designed as out
The semicircle strip hole of mouth, can be easy to during assembling two valve stem heads are installed to the installation in the hole of valve gap bridge.Otherwise
Because fit clearance is little, align two valve stems entrance installing holes wastes time and energy simultaneously very much, and can be obvious by above measure
Improve efficiency of assembling.
Brief description
Fig. 1 is the principle assumption diagram that this utility model valve is passed a bridge.
Fig. 2 is this utility model example structure figure.
Specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, principle of the present utility model and structure are further described.
The four-valve engine valve being easy to assemble is passed a bridge, and its structure is: valve gap bridge 1 is provided with two valve stems and installs
Hole, first valve stem installing hole 2-1 is strip hole, and one end of this strip hole is semicircle, and other end is opening；Second
Valve stem installing hole 2-2 is circle, and using duaspiracle bar installing hole as location hole.The top that valve is passed a bridge is a plane
3, Rocker arm 5 is passed through this plane and is contacted with valve gap bridge.Two valve stem installing holes are equipped with oil leab 4, and two valves 6 are respectively
It is installed on two valve stems and in the hole is installed.Valve stem is entered by the lubricating oil of rocking arm interior splashing in the hole is installed, be valve
Lubrication is provided between club head and valve gap bridge.
One of valve two valve stem installing holes of gap bridge are processed as the semicircle strip hole of opening, so in assembling
When valve stem just can be easily advanced into the strip hole of this opening semicircle, valve stem head is just connect with semicircular position
Touch and coincide.Because valve upper another one valve stem installing hole of passing a bridge is circle, so can be so that valve stem using this hole
It is accurately positioned with installing hole.This utility model application effect on 4102 type Diesel engines is good.
