Abstract
The invention provides a technical scheme of a double-lock-pin middle-arranged central locking phaser. The double-lock-pin middle-arranged central locking phaser comprises a correct timing sprocket and a rotor, and is characterized in that the correct timing sprocket is provided with a main lock pin hole and a secondary lock pin hole, the main locking pin hole is formed in the middle position of a maximum delaying angle of the correct timing sprocket and a maximum advancing angle of the correct timing sprocket, the secondary lock pin hole is formed in the position of the maximum delaying angle of time correcting sprocket, a main lock pin and a secondary lock pin are arranged in the rotor, the main lock pin corresponds to the main lock pin hole, the secondary lock pin corresponds to the secondary lock pin hole, and a connecting oil passage connected with the main lock pin, the secondary lock pin and an engine oil control valve is arranged in the rotor. The double-lock-pin middle-arranged central locking phaser can improve the control accuracy and responding speed of a cam phaser more accurately and more rapidly, and better improve the economy of fuel oil and the performance of an engine and lower emission.
Description
Technical field
What the present invention relates to is a kind of VVT engine phase position device, the central locking phase discriminator of especially a kind of twin-lock pin middle.
Background technique
In the prior art, known technology is: along with the raising that engine power performance, economical and low pollution emission are required, increasing motor car engine has adopted Variable Valve Timing, the locking phase discriminator that tradition is used is only provided with a lock pin, and phase discriminator speed of response is slower, and control accuracy is also not high enough, be difficult to reach the effect of the valve timing that provides best, caused automobile fuel consumption higher, the situation that exhaust emissions is more, this is the existing deficiency of prior art.
Summary of the invention
Object of the present invention, be exactly for the existing deficiency of prior art, and the technological scheme of a kind of twin-lock pin middle central authorities locking phase discriminator is provided, this scheme can more accurately improve control accuracy and the speed of response of cam phaser more rapidly, better improves fuel economy, improves engine performance and reduces discharge.
This programme is achieved by the following technical measures: the central locking phase discriminator of a kind of twin-lock pin middle, include timing sprocket and rotor, and it is characterized in that: on described timing sprocket, be provided with master lock pin-and-hole and secondary lock pin-and-hole; Described master lock pin-and-hole master lock pin-and-hole is arranged in the maximum slow neutral position to angle and timing sprocket full aduance of timing sprocket; Described secondary lock pin-and-hole is arranged on the position at the maximum sluggish angle of timing sprocket; Described internal rotor is provided with master lock pin and secondary lock pin; The corresponding locking master lock of described master lock pin pin-and-hole; The corresponding locking secondary lock of described secondary lock pin pin-and-hole; In described rotor, be provided with the connection oil duct that connects master lock pin, secondary lock pin and OCV Oil Control Valve.
As this programme preferably: master lock pin and secondary lock pin are all connected on rotor by Returnning spring separately.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to moving by the oil circuit break-make control master lock pin of OCV Oil Control Valve and the locking of secondary lock pin in this scheme, master lock pin-and-hole position is in the maximum slow neutral position to angle and full aduance, secondary lock pin-and-hole is in position, maximum sluggish angle, this mechanism has changed the changeless state of phase place in conventional engines, in motor nominal situation, it can provide best valve timing, not only effectively promote engine power, moment of torsion, reduced oil consumption and exhaust emissions simultaneously.
As can be seen here, the present invention compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The phase discriminator that Fig. 2 is is at the structural representation of initial phase.
Fig. 3 is the structural representation that phase discriminator lags behind and regulates.
Fig. 4 is that phase discriminator is at the structural representation of any holding position.
Fig. 5 is the structural representation that phase discriminator is reconciled in advance.
In figure, 1 is timing sprocket, and 2 is rotor, and 3 is master lock pin, and 4 is secondary lock pin, and 5 is master lock pin-and-hole, and 6 for connecting oil duct, and 7 is spring, and 8 is OCV Oil Control Valve, and 9 is secondary lock pin-and-hole.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
By accompanying drawing, can find out, this programme for having master lock pin-and-hole and secondary lock pin-and-hole on timing sprocket 1, master lock pin-and-hole position is in that maximum secondary lock pin-and-hole is in position, maximum sluggish angle late to the neutral position of angle and full aduance, by oil duct C1 and oil duct D, controls the unlatching of master lock pin and secondary lock pin and locked, when spool is in initial position, main oil gallery C1 sealing, release oil duct C2 sealing, lock pin oil duct D return opening is opened, rotor locking, phase discriminator is not worked.
When phase discriminator need to lag behind adjusting, release oil duct C1 and lock pin oil duct D path, the release of master lock pin, oil duct C2 and oil duct B1 path, B is oil-filled in hysteresis chamber, oil duct A1 and oil duct E path, chamber A oil extraction in advance, phaser rotor regulates to hysteresis direction.
When phase discriminator need to keep phase place, release oil duct C1 and D path, keep master lock pin and the release of secondary lock pin, and oil duct A1, B1, C2 open circuit, and now phase discriminator shifts to an earlier date chamber A and hysteresis chamber B oil mass is constant, reaches the object that keeps phase place.
When phase discriminator need to be reconciled in advance, oil duct C1, oil duct D open circuit, and keep master lock pin release and the release of secondary lock pin, oil duct B1 and oil duct E path, and the B oil extraction of hysteresis chamber, oil duct C2 and oil duct A1 path, chamber A is oil-filled in advance, and phaser rotor 7 is to direction conciliation in advance.
When phase discriminator is during in anticipated future position; sudden engine is shut down; oil duct A1; oil duct D and oil duct E path, when engine restarting, stator rotation under bent axle drives; rotor is under the effect of camshaft negative torque; towards the motion of hysteresis direction, when master lock pin moves to neutral position, lock pin is locked, guarantees the smooth startup of motor.
When phase discriminator is during at lag position; sudden engine is shut down; oil duct A1; oil duct D and oil duct E path; now secondary lock lock is dead; when engine restarting; secondary lock lock extremely can guarantee motor effectively start, is in lag position, adjustable spool when ECU detects camshaft; make oil duct C1 and oil duct D path; the release of secondary lock pin, chamber A oil pressure in advance and Returnning spring acting in conjunction under, the rotor short time is interiorly moved towards anticipated future position; locked when neutral position, to guarantee the follow-up clean boot of motor.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
