Description

Novel camshaft phase regulator

Technical field

The utility model belongs to startup engine continuous variable timing system technical field, more particularly to a kind of new type of cam Axle phase regulator.

Background technology

VVT technology（VVT）, inlet and outlet can be converted when engine is operated（Or two）Liter Journey, timing and duration angle.VVT technology changes the changeless state of port timing in conventional engines, Optimal valve timing is provided in the range of engine operating condition, preferably solve high rotating speed and the slow-speed of revolution, big load with The contradiction of dynamic property and economy under Smaller load, and improving waste gas discharge down to a certain degree.Further, it is variable Valve timing system technology can be used to reduce engine pumping loss, accelerates intake velocity, improves mixed gas quality, changes residual Remaining waste gas coefficient；Intake efficiency, the combustion process of final improvement engine are improved, makes dynamic property, economy, emission performance and sound Performance is answered to obtain comprehensive raising.

Actuator is calculated as automobile VVT engine system critical components, receiving from ECU according to actual condition Optimal valve instruction, change motion state, hydraulic flow improves engine performance, the performance quality of actuator is by direct shadow Ring the overall performance of VVT systems.

Actuator（Cam phase adjuster）By shell（It is fixed on timing gears）And rotor（It is fixed on camshaft） Composition.The effect of rotor is to control the angle that rotor is adjusted by the latch gear on rotor, to reach that valve-control adjusts machine Effect of system regulation air valve angle.When valve-control Regulation mechanism does not work, latch gear fixed rotor and sprocket wheel or bonnet Deng part relative position.When valve-control Regulation mechanism is started working, hydraulic oil promotes lock pin（Latch）, make rotor with Miscellaneous part releases lockup state.Rotor drives cam axle, so as to realize adjustment valve-control under the promotion of hydraulic oil Function.

Existing automobile VVT actuators locking structure is all to move cotter way, or opening and closing on the cover board in sprocket wheel top opening and closing Dynamic cotter way, designs lock pin aperture on rotor, and plug and latch, the portion such as fixed rotor and sprocket wheel or bonnet are assembled in lockpin hole Part relative position.Such structure, and processing plug hole and lock pin aperture, the bad control of concentricity, concentricity directly affect dress Match somebody with somebody, while influence the locking quality of latch, latch easily in a low voltage state, is opened dumb or locked beaten not Open.If opening and closing moves cotter way on the cover board, the thickness of cover plate needs to thicken, and is no small raising for cost.

The problem of for the above, it is desirable to provide a kind of novel camshaft phaser adjuster detent configuration solves above-mentioned ask Topic.

The content of the invention

The purpose of this utility model is that the defect for overcoming prior art to exist opens ineffective there is provided one kind solution lock pin low pressure Novel camshaft phase regulator that is living or not opening.

Realizing the technical scheme of the utility model purpose is：A kind of novel camshaft phase regulator, with rotor, stator And sprocket wheel；The stator is fixed with sprocket coaxiality；The rotor is installed in stator；It is characterized in that：The side of the rotor Offer the stop cotter way communicated with oilhole；The side of the stator offers lock pin aperture；It is provided with the lock pin aperture Latch；The outer end of the latch is provided with jump ring；The jump ring is arranged on the inwall of lock pin aperture and offered for preventing Only in the jump-ring slot of latch ejection lock pin aperture.

The outer end of latch described in above-mentioned technical proposal is axially drilled with spring eye, the spring eye and is placed with spring；Institute State and pushed down between the outer end of spring and jump ring by pad.

After adopting the above technical scheme, the utility model has following positive effect：

（1）The utility model side lock pin, it is not necessary to plug.When processing lock pin aperture, in the absence of lock pin aperture with blocking up It is not present under the bad situation of head bore concentricity, latch low oil pressure and opens situation that is dumb or not opening.

（2）The utility model stop cotter way is communicated with oilhole, and the oil pressure of expense pressure, latch energy are applied more than during work Response is opened in very short time, and camshaft phase adjuster governing response mechanism is sensitiveer.
