Description
Technical field
This patent disclosure relates generally to the rotation of a kind of continuous variable valve timing (hereinafter referred to as CVVT)
Rotation control apparatus.
Background technology
Statement in this part only provides background information related to the present invention and does not constitute existing
Technology.
Generally, CVVT is applied to vehicle to reduce waste gas and to improve fuel efficiency and output.
First common CVVT structure will be described with reference to Figure 1 to help to understand the present invention.
As shown in FIG. 1, CVVT includes the cam of the anglec of rotation for detecting camshaft
Shaft position sensor 11, and for detecting the crankshaft position sensor 12 of the anglec of rotation of bent axle.
Driven VVT unit 15 by bent shaft-driven Timing Belt 14, and changeable air valve is just
Shi Danyuan 15 uses vane type (vane type).
ECU (electronic control unit) 13 responds from cam-position sensor 11 and crank position
The signal of sensor 12 according to the valve timing of the position control cam of bent axle, and from
The control signal of ECU13 be sent to oil control valve 16 (this oil control valve 16 be fed with from
The engine oil of oil pump for engine), therefore cam rotates.
When oil control valve 16 respond the control signal from ECU13 cam is rotated time, convex
Wheel position sensor 11 detect the position of camshaft and feed back to ECU13, ECU13 based on
The positional information assessment rotation amount of cam of the camshaft of feedback and based on the cam assessed
The signal being used for controlling camshaft location is sent back oil control valve 16 by rotation amount.According to this control
Logic, carries out continuous variable control to valve timing.
On the other hand, in order to successfully implement feedback function, will be according to crank position and cam position
Put to the control logical mappings of oil control valve 16 to ECU13.Therefore, when the camshaft mapped
When position is different with the cam position detected by cam-position sensor, ECU controls oil control valve
16 to increase/to reduce the rotation of camshaft.
Fig. 2 is to show that valve opens the timing curve chart relative to crankshaft angles.ECU13 according to
Crankshaft angles controls valve in exhaust stroke and induction stroke and controls timing, generally, ECU13
In exhaust stroke and induction stroke, shift to an earlier date valve timing or postpone valve timing.
CVVT system reduces pumping loss by increasing inlet valve and the valve overlap of exhaust valve
And then improvement fuel efficiency, by the optimization of valve overlap and internal exhaust gas recirculation are realized unburned
Burn the incendiary effect again of gas, thus reduce waste gas.
As shown in Figure 3, recently, the CVVT system of intermediate phase eliminates existing CVVT system
The response district of system and the restriction of working area.This intermediate phase CVVT had both controlled the position of cam
Not in (air inlet) position the most in advance the most not in (aerofluxus) position postponed most, but in
Between position, thus response rapidly and can increase the usable floor area of cam, thus improves fuel effect
Rate and minimizing waste gas.
In intermediate phase CVVT, the lock pin on rotor is locked between advance chamber and delay chamber
In lockpin hole, the RPM of electromotor reduces simultaneously, thus prepares for follow-up engine start.
When the RPM of electromotor reduces, lock pin is automatically locked into the behavior of lockpin hole and is referred to as " self-locking ".
Self-locking is that one returns to exact position and without specially adjusting with making CVVT system mechanics
Whole function, thus at period that CVVT system does not uses (that is engine idle or open
Time dynamic) it is able to maintain that the job stability of electromotor.
But, arrive, when valve timing, the position postponing most or more postponing and do not return to
Between phase place, and during the engine idle of vehicle, vacuum tank is not likely to be in vacuum and vacuum tank
The pressure in portion may be increased up atmospheric pressure, thus utilizes the braking ability possibility of vacuum tank vacuum
It is deteriorated.
Additionally, when reaching the position that postpones most and do not return to intermediate phase valve timing,
The excessive overlapping of valve timing may be produced between inlet valve and exhaust valve, so that electromotor
Job stability reduce and electromotor vibration increase, in some cases, engine stop.
It is to say, the so-called lock pin self-locking in intermediate phase CVVT may will not be entered automatically
OK, thus when rotor and lock pin be in position the most in advance or postpone most position time, start
Machine stops and owing to the negative pressure of improper generation thus actuating system may not work.
More than it is meant only to help to understand the background of the present invention, it is no intended to mean as art technology
Well known to personnel.

Rotor 100 is sentenced and is begun on the direction in advance of rotor 100 between rotor 100 and stator 300
Apply moment of torsion eventually and realize the self-locking of lock pin 900；And stop part 700, it locks degree of advance
The side of compensating unit 500 after degree of advance compensating unit 500 arrives predetermined position
Release degree of advance compensating unit 500.
According to the present invention, degree of advance compensating unit 500 is arranged on rotor 100 and sentences at rotor
All the time apply moment of torsion and realize lock pin on the direction in advance of rotor 100 between 100 and stator 300
The self-locking of 900.
As shown in FIG. 3, degree of advance compensating unit 500 is the coil (example winding a few
Such as metal wire or bar), especially, it can be bias spring.Degree of advance compensating unit 500
Have be connected to rotor 100 (in order to move therewith, be attached the most rigidly, fixing or
Immovably connect) the first end 510 and be connected to stator 300 (attachment the most rigidly,
Fixing or immovably connect) the second end, thus compensating unit 500 is in direction in advance
Upper applying elastic force makes advance chamber launch all the time.Stop part 700 is inserted in rotor 100,
First end 510 of degree of advance compensating unit 500 is positioned at this rotor 100, and this backstop
Part 700 can have cylindrical shape, for example, sells.For degree of advance compensating unit 500
The rotating gravure 110 that first end rotates in predetermined scope is formed on rotor 100.
When rotor 100 rotates up at party in delay, degree of advance compensating unit 500 is compressed,
And when rotor 100 is when side rotates up in advance, degree of advance compensating unit 500 is pressed by it

Side rotates up, when the rotor 100 rotated arrives intermediate phase, automatically real by electromagnetic valve
Execute lock pin 900 and be locked into the self-locking of lockpin hole 910.
On the contrary, Fig. 6 is the view of the state postponed most showing Fig. 4, wherein in order to from prolonging most
State transformation is to self-locking position late, has been rotated out the lock pin 900 of the rotor 100 of intermediate phase
Rotate up in side in advance, thus realize self-locking.But, even will be identical with correlation technique
The rotation number of electromotor be applied to advance chamber with identical oil pressure, the moment of torsion of rotor 100 also by
Increase in the elastic force possessed by the delaying state (winding the most in advance) of Fig. 4,
So that rotor 100 can more easily overcome the moment of torsion of camshaft and the frictional force of valve system
And rotate to intermediate phase.Therefore lock pin 900 can be locked into lockpin hole 910 by electromagnetic valve, from
And realize self-locking.Stop part 700 prevents degree of advance compensating unit 500 from constantly being extruded and surpassing
Go out intermediate phase such that it is able to guarantee accurate intermediate phase and get rid of bad self-locking.The most just
It is to say, when degree of advance compensating unit 500 arrives the position realizing self-locking, and makes advance angle
Degree compensating unit 500 is no longer influenced by stop part 700 and extrudes, thus it is single to utilize degree of advance to compensate
The power making cam rotate is removed by unit 500.
It is to say, by increasing in cam torque difference between delaying state and self-locking state
Add the load of degree of advance compensating unit 500, and by the backstop when arriving stop position
Part 700 stops degree of advance compensating unit 500, and CVVT no longer rotates up in side in advance, from
And accurate intermediate phase can be realized and prevent bad self-locking.
Therefore, according to the rotating control assembly of CVVT, due to bearing of degree of advance compensating unit
Carry and increase to delaying state to the cam difference in torque between self-locking state, and in rotor profit
Prevent degree of advance from compensating by stop part when arriving self-locking position with degree of advance compensating unit
Finite element rotation, therefore, it is possible to prevent bad self-locking and as it ensure that predetermined accurate in
Between phase place and guarantee the more stable work of CVVT.
