Description

Motorcycle dual overhead camshaft engine V air inlet phase continuous variable mechanism

Technical field

The present invention relates to the distribution device of motor, relate in particular to a kind of motorcycle Dual Over Head Camshaft air inlet phase continuous variable mechanism that is used for.

Background technique

Engine variable-valve correct time (VVT, Variable Valve Timing) technology is the new technology that is applied to motor car engine in recent years gradually, should technology also little by little be applied on the motorcycle engine simultaneously.But that uses this technology only has a big displacement motorcycle engine of only a few, like GSF400 V of Suzuki etc.

For some small displacement motorcycle engine that is the basis with the structural type of Dual Over Head Camshaft; This technology also is not used widely; Its main cause is that the size of motorcycle dual overhead camshaft engine V of medium and small discharge capacity is less, using should technology the time, how to change under the little situation at former machine; Reasonably arrange VVT controller and corresponding oil duct thereof, just become difficult point.Therefore,, need reasonably design a kind of air inlet phase continuous variable mechanism, to enlarge the application of VVT controller to the motorcycle dual overhead camshaft engine V.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of motorcycle dual overhead camshaft engine V air inlet phase continuous variable mechanism; This mechanism can continuously change the phase angle of intake cam; It is simple in structure, layout is compact, low cost of manufacture, can effectively improve power character, Economy and the emission performance of motorcycle dual overhead camshaft engine V in whole rotating speed and load condition scope.

For this reason; The technological scheme that the present invention adopted is: a kind of motorcycle dual overhead camshaft engine V air inlet phase continuous variable mechanism, and comprise cylinder head, be bearing in admission cam shaft and exhaust cam shaft in the cylinder head, key is: in the upper end of said admission cam shaft the VVT controller is installed; Have the OCV Oil Control Valve fixed base in the outside of cylinder head; On the OCV Oil Control Valve fixed base, OCV Oil Control Valve is installed, said VVT controller comprises housing, be installed in the housing and with the wide impeller of housing, housing, the flange plate that is arranged on the housing upside are in the same place through bolton with the sprocket wheel that is arranged on the housing downside; On the inner ring surface of said housing, be evenly equipped with prominent piece; On the cylindrical bosses of said impeller, be evenly equipped with blade, said blade and prominent piece are arranged in a crossed manner, and the inner ring surface cunning of blade end face and housing is closed; The end face of prominent piece and the wheel hub cylndrical surface cunning of impeller are closed; Thereby form first oil pocket and second oil pocket of sealing in the both sides of each blade, said first oil pocket communicates with first valve opening on the OCV Oil Control Valve fixed base through the first oil duct system, and second oil pocket communicates with second valve opening on the OCV Oil Control Valve fixed base through the second oil duct system.

The present invention installs the VVT controller at admission cam shaft one end of motorcycle dual overhead camshaft engine V; Impeller and admission cam shaft are synchronized with the movement; Housing, flange plate and sprocket wheel are synchronized with the movement, and the oil pressure of first oil pocket and second oil pocket of VVT controller through control blade both sides is poor, and it is clockwise or rotate counterclockwise with respect to housing to make impeller drive admission cam shaft; Thereby the phase angle of adjustment intake cam, the direction of its rotation is controlled by OCV Oil Control Valve.

When needing to shift to an earlier date the air inlet phase angle, the working position of adjustment OCV Oil Control Valve makes machine oil get into first oil pocket by the first oil duct system; The machine oil of second oil pocket is through the second oil duct system oil return release; The first oil pocket oil pressure is higher than second oil pocket, and pressure oil promotes impeller and clockwise rotates, and impeller drives admission cam shaft and clockwise rotates with respect to housing; Realize that intake cam rotates in advance, the angle of rotation is regulated by OCV Oil Control Valve; When needs hysteresis air inlet phase angle; The working position of adjustment OCV Oil Control Valve makes machine oil get into second oil pocket by the second oil duct system, and the machine oil of first oil pocket is through the first oil duct system oil return release; The oil pressure of second oil pocket is higher than first oil pocket; Pressure oil promotes impeller and rotates counterclockwise, and impeller drives admission cam shaft and rotates counterclockwise with respect to housing, realizes intake cam hysteresis rotation.As stated, through shifting to an earlier date or the rotation that lags behind of the relative housing of impeller, thereby realize continuously changing the function at valve timing phase angle; When needs air inlet phase angle is constant; The working position of adjustment OCV Oil Control Valve makes the first oil duct system and the second oil duct system all be in cut-off state, the oil pressure balance of first oil pocket and second oil pocket; Impeller and housing rotate synchronously, and valve timing diagram remains unchanged.Thereby; The present invention can improve power character, fuel economy and the emission performance of motorcycle dual overhead camshaft engine V in the whole service operating mode; And simple in structure, layout compactness; Change to former machine is little, is adapted at extensive use on the motorcycle engine that the structural type with Dual Over Head Camshaft is the basis.

Preferred as this programme, a said blade is provided with axial hole therein, and said sprocket wheel is provided with the attachment hole corresponding with axial hole; Lock pin is housed in axial hole; Mid-rear portion at lock pin is provided with the stage clip mounting hole, in this stage clip mounting hole stage clip is housed, and the other end and the flange plate of stage clip offset; Said lock pin can insert in the attachment hole under the effect of stage clip; Said lock pin is the locking section of minor diameter near an end of sprocket wheel, forms annular oil cavity between this locking section and the axial hole, and this annular oil cavity connects through oil groove and the first contiguous oil pocket of said lock pin that is arranged on the sprocket wheel.When the motorcycle dual overhead camshaft engine V quit work, stage clip promoted lock pin and inserts in the attachment hole, limits relatively rotating of impeller and housing, and impeller and housing projection clash into and the generation noise when preventing engine start.When needs change the air inlet phase angle, through the control of OCV Oil Control Valve, increase the oil pressure of first oil pocket, make the oil of first oil pocket flow into annular oil cavity through the oil groove in the sprocket wheel, force lock pin to withdraw from attachment hole, lock pin separates with attachment hole.
