Motivation.
Background technique
Engine valve actuating mechanism is one of basic system of engine, mainly includes valve group (valve, rocker arm and valve
Spring etc.) and valve driving group (camshaft, timing gears, camshaft signal disk, tappet and push rod etc.), engine valve actuating mechanism
The requirement of (I. C engine distribution mechanism) according to the working cycles and ignition order carried out in each cylinder of engine, time opening
Inlet and outlet door with each cylinder is closed, enables fresh combustion mixture or air to timely enter cylinder, exhaust gas is able in time
It is discharged from cylinder, in compression and the sealing in expansion space stroke, closing valve guarantee combustion chamber.The requirement of engine valve actuating mechanism
It is structural parameters and form advantageously reduces air inlet and exhaust resistance, and the unlatching of the start-up time of inlet and outlet door and continuity
Time must be accurate, makes air inlet and exhaust all as far as possible sufficiently, to obtain biggish power torque and emission performance.
Realize inlet and exhaust valve according to precise moments time opening or closing, it is necessary to the signal acquisition of camshaft is carried out,
Therefore camshaft signal disk is most important.Camshaft signal disk is equivalent to the switch of control engine, the design of phase angle
And accurate control, the co-ordination of each cylinder of engine is played a crucial role, camshaft signal disk provides signal
To camshaft phase sensor, signal is passed to ECU again by phase detector, and ECU receives the signal and then controls engine spray
Oil and igniting.
The camshaft signal disk of available engine mostly uses greatly steel plate (or powder metallurgy) rammed disk as one
Individual components are assembled with camshaft again.More specifically, the camshaft signal disk generally require interference be fitted in it is convex
On the wheel shaft diameter of axle, due to there is timing events, so camshaft signal disk is needed to add with the positioning of camshaft keyway or the two
Work mark, to achieve the purpose that correctly to assemble, it is seen that such structure processing technology is cumbersome, and reliability is bad, transports in engine
Easily there is the case where camshaft signal disk loosens after a period of time in row.
Utility model content
Therefore, the technical problem to be solved by the present invention is to provide a kind of timing gears, valve drive assemblies, start
Machine integrates camshaft signal disk on timing gears, greatly simplifiing the assembling process of timing gears and camshaft, more just
In maintenance, good reliability.
To solve the above-mentioned problems, the utility model provides a kind of timing gears, including timing gears ontology, camshaft letter
Dialer, the camshaft signal disk and the timing gears ontology integrated molding.
Preferably, the camshaft signal disk and the timing gears ontology integrated molding by the way of forging.
Preferably, the camshaft signal disk has multiple signal teeths and a multiple empty teeth, multiple signal teeths with it is multiple
The sky tooth is staggered on the periphery of the camshaft signal disk, and the signal teeth, the angle of empty tooth and engine are matched
Gas phase matches.
Preferably, there are timing marks on the timing gears ontology.
The utility model also provides a kind of valve drive assemblies, including above-mentioned timing gears.
Preferably, the valve drive assemblies further include camshaft, between the timing gears ontology and the camshaft
Key connection.
The utility model also provides a kind of engine, including above-mentioned valve drive assemblies.
A kind of timing gears provided by the utility model, valve drive assemblies, engine, due to by camshaft signal disk with
Timing gears ontology integrated molding is needed in the prior art to directly eliminate by the camshaft signal disk and camshaft
The process of assembling, which strongly simplifies the assembling process of timing gears and camshaft, easily facilitate maintenance, good reliability.

Specific embodiment
In conjunction with referring to shown in Fig. 1, Fig. 2, embodiment according to the present utility model provides a kind of timing gears, including timing
Gear 1, camshaft signal disk 2, the camshaft signal disk 2 and 1 integrated molding of timing gears ontology.The technology
In scheme, due to by camshaft signal disk 2 and 1 integrated molding of timing gears ontology, to directly eliminate in the prior art
The process for assembling the camshaft signal disk 2 with camshaft 3 is needed, which strongly simplifies the dresses of timing gears and camshaft
With process, maintenance, good reliability are easily facilitated.Further, the camshaft signal disk 2 is adopted with the timing gears ontology 1
With the mode integrated molding of forging, components are formed by the way of forging with higher structural strength.
Preferably, the camshaft signal disk 2 has multiple signal teeths 21 and multiple empty teeth 22, multiple signal teeths 21
It is staggered with multiple empty teeth 22 on the periphery of the camshaft signal disk 2, and the angle of the signal teeth 21, empty tooth 22
Degree matches with gas distribution phase of engine.Further, the multiple signal teeth 21 and multiple empty teeth 22 are mutual in position
Asymmetry, such arrangement can effectively identify the firing order of difference cylinder, accurately transmit camshaft phase information,
Improve the stationarity of engine operating
Further, there are timing marks on the timing gears ontology 1, have on the timing gears ontology 1
Timing marks can be aligned with camshaft 3, thus can accurately guarantee the accuracy of the phase information of camshaft.
