Description

The valve timing controller

Technical field

The disclosure relates to the valve timing controller.

Background technique

JP-11-132014A(USP No.6,039,016) a kind of valve timing controller, the suction valve of its controlling combustion engine or the valve timing of outlet valve have been described.This valve timing controller has in advance oil pressure chamber and hysteresis oil pressure chamber between the vane rotor that rotates relative to one another and housing.This valve timing controller also has the torsion spring that produces relative rotatable phase between vane rotor and housing.

For example, torsion spring produces the moment of torsion of bias voltage vane rotor to rotate in direction in advance with respect to housing.Corresponding with the moment of torsion of torsion spring, the valve timing controller produces phase difference by the pressure of control hydraulic fluid between vane rotor and housing, so that the valve timing of control suction valve or outlet valve.

Because the two ends of torsion spring all tilt with respect to the plane perpendicular to axial rotary, so the central axis of torsion spring can tilt with respect to spin axis when torsion spring is fastened to the valve timing controller.In the case, the load that is produced by the moment of torsion of torsion spring also tilts with respect to the spin axis direction.If housing tilts with respect to vane rotor, between vane rotor and housing, easily produce so wearing and tearing on the spin axis direction.And if torsion spring tilts with respect to the spin axis direction, when making the valve timing controller, the assembling of parts such as fitted bolt may difficult so.

Summary of the invention

Target of the present disclosure provides a kind of valve timing controller, and wherein limit blade rotor and housing relative to each other tilt.

According to an example of the present disclosure, a kind ofly come open and close suction valve and outlet valve and comprise housing, vane rotor, lining, disc spring and holder by changing at least one the open and close valve timing controller regularly that rotatable phase between live axle and the driven shaft controls in suction valve and the outlet valve by the driving force rotation driven shaft with the live axle of internal-combustion engine.The rotation of housing in live axle and driven shaft.In live axle and driven shaft another of vane rotor rotates, and has the blade that is contained in the receiving cavity that is limited in the housing.Vane rotor uses the pressure of the hydraulic fluid that is fed to pressure chamber to change with respect to the rotatable phase of housing, and pressure chamber limits by separating receiving cavity with blade.The cylindrical shape lining is fixed to vane rotor, and at relatively rotatable state lower support housing.Disc spring is used for lining and has the first end that engages with vane rotor and the second end that engages with housing.Disc spring produces the vane rotor bias voltage with the bias voltage moment of torsion with respect to housing rotary.Holder when the plane that is projected into perpendicular to the spin axis direction at least one some place contact disc spring.Holder remains the posture of disc spring and spin axis direction keeping parallelism.

So when the disc spring contact holder, the central axis of disc spring becomes and is parallel to the spin axis direction, and is parallel with the spin axis direction thereby the posture of disc spring remains.Therefore, at housing and vane rotor because the moment of torsion of disc spring and when rotating relative to each other, the moment of torsion of disc spring becomes perpendicular to the spin axis direction.Thereby, the relative tilt on the spin axis direction between housing and the vane rotor can be reduced, and the wearing and tearing between housing and the vane rotor can be reduced.

And disc spring displacement diametrically is limited, and the parts that therefore are positioned at contiguous disc spring can be arranged neatly.

In addition, because holder and disc spring contact with each other at this some place, so the area of contact between holder and the disc spring is compared and can be reduced with the situation that holder and disc spring contact with each other in the plane.So the surface friction drag between holder and the disc spring can reduce.

Controller 60 is described with reference to Fig. 1.Controller 60 comprises switching valve 61 and electronic control unit (ECU) 80.Switching valve 61 is with passage 62, hysteresis passage 63, pumping passage 64 and discharge route 65 are connected with 66 in advance.Oil pump 67 is installed in the pumping passage 64.By the pumping of pumping passage 64 oil corresponding with working fluid, and oil is discharged towards switching valve 61 in the downstream by pumping passage 64 to oil pump 67 from fuel tank 68.Oil is discharged towards fuel tank 68 by

discharge route

65,66 from switching valve 61.

ECU80 is made of such as microcomputer electronic circuit, and except switching valve 61, also is electrically connected to a plurality of sensors, such as cam-angle sensor 81, crank angle sensor 82.Actual phase and target phase that ECU80 is relevant with respect to the engine phase position of crankshaft 92 with camshaft 94 according to the output calculating of sensor, and be used for the driving current of switching valve 61 in order to supply power to switching valve 61 according to result of calculation control.

The electric energy that is fed to switching valve 61 is controlled by ECU80.Switching valve 61 is the magnetic slide valve type valves with spool 613, spool according to by activate electromagnetic actuators 611 driving force that driving direction produces and Returnning spring 612 between the restoring force that the opposite direction opposite with driving direction produces balance and move in the axial direction.Switching valve 61 according to the driving current of supplying with actuator 611 by spool 613 move axially switch pumping passage 64 and discharge route 65 and be connected the passage of being connected with the hysteresis passage with respect to passage 62 in advance and connect.

The operation of valve timing controller 1 will be described below.When motor 91 stopped, catch piston 27 was coupled to cooperation owing to the biasing force of spiral compression spring 29 at maximum anticipated future position place and encircles 117.

When engine start, oil pump 67 activates and flows into hysteresis oil pressure chamber 105-108 from the hydraulic fluid that oil pump 67 is discharged via hysteresis passage 201-204.Therefore, catch piston 27 105 receives oil pressure by passage 221 from hysteresis oil pressure chamber.When oil pressure rose to predetermined pressure, catch piston 27 was separated with cooperating ring 117.Thus, vane rotor 20 and housing 10 become and can rotate relative to each other.

The below will describe hysteretic operation.The energising of ECU80 control switching valve 61, thus switch in advance passage 62 and hysteresis passage 63 with respect to the coupled condition of oil pump 67.Therefore, when hysteresis passage 63 communicates with oil pump 67, flow into hysteresis oil pressure chamber 105-108 by the oil of oil pump 67 pumpings via hysteresis passage 63 and hysteresis passage 201-204.And at this moment, the oil of oil pressure chamber 101-104 is discharged to fuel tank 68 via shifting to an earlier date passage 111-114 and shifting to an earlier date passage 62 in advance.Thereby oil pressure is applied to towards the blade 21-24 of hysteresis oil pressure chamber 105-108, and vane rotor 20 has relative rotation with respect to housing 10 on hysteresis direction Y.

The below will describe in advance operation.When in advance passage 62 communicates with oil pump 67, by the oil of oil pump 67 pumpings via passage 62 in advance and in advance passage 111-114 flow into and shift to an earlier date oil pressure chamber 101-104.And at this moment, the oil of hysteresis oil pressure chamber 105-108 is discharged to fuel tank 68 via hysteresis passage 201-204 and hysteresis passage 63.Thereby oil pressure is applied to towards the blade 21-24 that shifts to an earlier date oil pressure chamber 101-104, and vane rotor 20 has relative rotation with respect to housing 10 on the direction X in advance.

Thereby hydraulic fluid is switched from the passage that oil pump 67 is fed to, thereby control shifts to an earlier date the oil pressure of oil pressure chamber 101-104 and the oil pressure of hysteresis oil pressure chamber 105-108.Therefore, vane rotor 20 is controlled to control valve regularly with respect to the rotatable phase of housing 10.In addition, in the valve timing control time, ECU80 carries out the feedback control of switching on about switching valve 61 in the actual valve timing of expulsion valve 99 mode consistent with the target valve timing.Thereby valve timing can be controlled exactly.

When engine stop, because oil pump 67 also stops, so oil no longer is fed in advance passage 62, also is not fed to hysteresis passage 63.Then, according to the restoring force of disc spring 40, vane rotor 20 has the relative rotation with respect to maximum anticipated future position, and catch piston 27 is coupled to cooperation ring 117.

For example, when motor 91 abends owing to engine failure etc., exist the situation that execution is restarted next time when catch piston 27 is not coupled to mounting ring 117.In this case, rotatable phase turns back to default location, at this default location, and can the moment of torsion in response to disc spring 40 starts with rotation blade rotor 20 in the stage by shaking at the crank of reboot time next time.

According to the first embodiment, holder 51 is contacting with disc spring 40 perpendicular to two some places in the cross section of spin axis direction O.Namely, the protruding part 511 of holder 51 has and forms the contact segment 512 of extending abreast with spin axis direction O.Thus, when disc spring 40 contact contact segment 51, it is parallel with spin axis direction O that the central axis Os of disc spring 40 becomes.Therefore, when housing 10 and vane rotor 20 relative to each other rotated, the moment of torsion of disc spring 40 applied perpendicular to spin axis direction O.Therefore, the relative tilt between housing 10 and the vane rotor 20 can reduce at spin axis direction O, and the wearing and tearing between housing 10 and the vane rotor 20 can reduce.

In the present embodiment, holder 51 has a plurality of protruding parts 511.That is, in the cross section perpendicular to spin axis direction O, holder 51 contacts with disc spring 40 at a plurality of somes place.Thus, because protruding part 511 side by side contacts with disc spring 40, the effect of proofreading and correct disc spring 40 postures can improve, so that the central axis Os of disc spring 40 and spin axis direction O become parallel to each other more reliably.
