Description
Technical field
It the utility model is related to a kind of engine drive mechanism, and in particular to a kind of engine connecting shaft mechanism and valve are just
When, lift continuous changeable mechanism.
Background technology
It is well known that the gas pedal of automobile is the opening angle of air throttle in fact, air comes air inlet by air throttle
Manifold, then enters cylinder compresses work by combustion by inlet valve again by atomizer oil spout and then mixing, after acting, gives up
Gas is discharged after silencer from exhaust valve through exhaust passage.But existing technology cannot preferably complete valve and start
Effectively control valve completes ventilation under any revolution of machine, so as to cause high oil consumption, power is low.
Utility model content
For the comprehensively solve above problem, in particular for the deficiency present in the prior art, the utility model provides one
Kind engine connecting shaft mechanism and valve timing, lift continuous changeable mechanism being capable of the comprehensively solve above problems.
To achieve the above object, the utility model uses following technological means：
A kind of engine connecting shaft mechanism, including stepper motor and the stem gear that is engaged with stepping motor gear output shaft,
Connecting shaft is further included, described connecting shaft one end vertically consolidates stem gear, centre consolidation tappet assembly；
The tappet assembly includes tappet and is socketed the sleeve of tappet；
The sleeve wall consolidates connecting shaft；
The stepper motor, connecting shaft and tappet assembly composition linkage are overall, stepper motor rotating control tappet assembly angle
Degree is tilted and resetted.
Further, the tappet length of the tappet assembly is more than length sleeve.
Further, the tappet assembly is multiple that spacing is consolidated between connecting shaft.
A kind of engine valve timing, lift continuous changeable mechanism, including cam pack, rocking arm and valve, the cam set
Part includes the cam on camshaft and camshaft, which is consolidated in rocking arm bottom, further include arranged on cam pack and rocking arm it
Between engine connecting shaft mechanism, which is above-mentioned engine connecting shaft mechanism, wherein engine connecting shaft mechanism
Tappet upper end abut cam ring around curved surface, lower end abuts rocking arm upper curved surface.
Further, the rocking arm is multiple to be connected by horizontal brace rod.
The utility model beneficial effect is：The utility model can design valve according to the operating mode difference of engine
Timing and Yang Cheng opening degree, engine is run reduction ventilation fuel-saving environmental protection under slow speed, assigned in middle revolution
To fuel-economizing and lifting power, power is lifted under high revolution.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure：1- stepper motors, 2- stem gears, 3- connecting shafts, 4- rocking arms, 5- valves, 6- sleeves, 7- tappets, 8- cams

Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
1st, as shown in Figure 1, the utility model includes：Stepper motor 1 and the connecting shaft engaged with 1 gear output shaft of stepper motor
Gear 2, further includes connecting shaft 3, and described 3 one end of connecting shaft vertically consolidates stem gear 2, centre consolidation tappet assembly；
The tappet assembly includes tappet 7 and is socketed the sleeve 6 of tappet 7；
6 barrel of sleeve consolidates connecting shaft 3；
The stepper motor 1, connecting shaft 3 and tappet assembly composition linkage are overall, 1 rotating of stepper motor control tappet assembly
Angle tilt and reset.
The tappet length of the tappet assembly is more than 6 length of sleeve.
The tappet assembly is multiple, and spacing is consolidated between connecting shaft 3.
A kind of engine valve timing, lift continuous changeable mechanism, including cam pack, Rocker arm 4 and valve 5, the cam
Component includes the cam 9 on camshaft 8 and camshaft 8, which is consolidated in Rocker arm 4 bottom, further include arranged on cam pack and
Engine connecting shaft mechanism between Rocker arm 4, the engine connecting shaft mechanism are above-mentioned engine connecting shaft mechanism, and wherein engine connects
7 upper end of tappet of axis mechanism abuts cam 9 and abuts Rocker arm 4 upper curved surface around curved surface, lower end.
The Rocker arm 4 is multiple, is connected by horizontal brace rod.
Specific work process：The crankshaft-position signal and engine revolution signal that Engine ECU is sent, are computed control step
Stepper motor 1, driving stem gear 2 rotate, and change the relative position of tappet 7 and cam 9, so as to change the timing (cam 9 of valve
When promoting 7 one end motion of tappet, 7 other end of tappet moves therewith, promotes Rocker arm 4 to drive valve 5 to move).7 one end of tappet
With 9 change in location of cam, 7 other end of tappet changes at the same time with Rocker arm 4 top-surface camber, and Rocker arm 4 drives valve 5 to make movement change
Change, so that the Yang Cheng increments of valve are increased, (timing and Yang Cheng for changing valve can improve engine under high revolution
Scavenging efficiency).
Above-mentioned embodiment is only intended to clearly illustrate the utility model example, and not to embodiment party
The restriction of formula.For those of ordinary skill in the field, other differences can also be made on the basis of the above description
The change or variation of form, there is no necessity and possibility to exhaust all the enbodiments, and thus amplify out aobvious and
The change or variation being clear to are still in the scope of protection of the utility model.
