Description
Technical field
The utility model relates to 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, cause automobile fuel consumption higher, the situation that exhaust emissions is more, this is the existing deficiency of prior art.
Model utility content
The purpose of this utility model, 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 utility model 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 utility model.
The phase discriminator that Fig. 2 is is at the structural representation of initial phase.
Fig. 3 is the structural representation that phase discriminator hysteresis regulates.
Fig. 4 is the structural representation of phase discriminator in 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.
Can find out by accompanying drawing, 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, controls the unlatching of master lock pin and secondary lock pin and locked by oil duct C1 and oil duct D, 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.
In the time that 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.
In the time that 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.
In the time that 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, in the time of engine restarting, stator rotation under bent axle drives; rotor is under the effect of camshaft negative torque; towards the motion of hysteresis direction, in the time that 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; in the time of 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 in the time of neutral position, to guarantee the follow-up clean boot of motor.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
