Along with constantly rising violently of oil price, every fuel-saving technique of motor also becomes the large attraction that businessmans praise highly the most, and in the high-tech of numerous and complicated, major part technology also rests on raising fuel efficiency, increases suction pressure, reduces intake temperature, alleviate the level of engine loading, do like this and cannot play good effect, can make automobile such as bearing capacity itself on the contrary, the abilities such as hundred kilometers of acceleration decline.
Model utility content
For above deficiency, the utility model provides a kind of camshaft mechanism realizing cylinder deactivation of engine work.
The technical solution of the utility model: a kind of camshaft mechanism realizing cylinder deactivation of engine work, comprise camshaft and cam, cam occurs with general cam and spline cam two kinds of forms, be wherein fixing assembly connection between general cam and camshaft, between spline cam and camshaft, realize sliding axially assembly connection by spline; Be provided with draw-in groove at the side of camshaft, draw-in groove have recess, the recess of draw-in groove and the protuberance of spline cam with the use of, and the position of draw-in groove upper recess is corresponding with valve.
The beneficial effects of the utility model: the engine cam axis mechanism adopting the utility model to provide can drive moving axially of general cam by camshaft, can when engine traction or rate request little achievement unit sub-cylinder cylinder deactivation work, reach cylinder deactivation effect, and then strengthen the Rate of load condensate of working cylinder, in making it to remain on, the running of large load economical consumption of fuel district, reach the object of fuel-economizing, and then reach economic aviation fuel object.
Cylinder stopping technique described in the utility model promotes mainly technology by what become huge discharge multi-cylinder car, disconnected cylinder technology is also referred to as Variable Displacement Technology, when referring to that motor runs at part load, by the fuel delivery of associated mechanisms cutout portion cylinder, igniting and intake and exhaust, stop its work, residue working cylinder Rate of load condensate is increased, to raise the efficiency, reduces fuel consume.

Embodiment
embodiment one
As shown in Figure 1, this four cylinder engine camshaft mechanism comprises a camshaft 1 and four cams, and described four cams are two general cam 2 and two spline cams 3.Wherein, be fixing assembly connection between general cam 2 and camshaft 1, between spline cam 3 and camshaft 1, realize sliding axially assembly connection by spline 4.Be provided with draw-in groove 5 at the side of camshaft 1, described draw-in groove 5 has two recesses, and described two recesses are corresponding with the protuberance of two spline cams 3 respectively, and on draw-in groove 5, the position of two recesses is corresponding with valve.
Motor not cylinder deactivation time, two general cam 2 and two spline cams 3 all corresponding with valve and in normal working.When needs cylinder deactivation, control camshaft 1 or the segment distance that moves right left, this segment distance can make two general cam 2 move to the left or to the right simultaneously, leaves corresponding valve, is not controlling corresponding cylinder and realize the opening and closing of valve.Meanwhile, two spline cams 3 slide axially relative to the spline 4 on camshaft 1 and make two spline cams 3 still be controlled on the position corresponding with valve due to the effect of two recesses on draw-in groove 5, so now two general cam 2 are cylinder deactivation state, and two spline cams 3 still normally work, namely four cylinders become two cylinders, as shown in Figure 2.
embodiment two
As shown in Figure 3, this six cylinder engine camshaft mechanism comprises a camshaft 1 and six cams, and described six cams are four general cam 2 and two spline cams 3.Wherein, be fixing assembly connection between general cam 2 and camshaft 1, between spline cam 3 and camshaft 1, realize sliding axially assembly connection by spline 4.Be provided with draw-in groove 5 at the side of camshaft 1, described draw-in groove 5 has two recesses, and described two recesses are corresponding with the protuberance of two spline cams 3 respectively, and on draw-in groove 5, the position of two recesses is corresponding with valve.
Motor not cylinder deactivation time, four general cam 2 and two spline cams 3 all corresponding with valve and in normal working.When needs cylinder deactivation, control camshaft 1 or the segment distance that moves right left, this segment distance can make four general cam 2 move to the left or to the right simultaneously, leaves corresponding valve, is not controlling corresponding cylinder and realize the opening and closing of valve.Meanwhile, two spline cams 3 slide axially relative to the spline 4 on camshaft 1 and make two spline cams 3 still be controlled on the position corresponding with valve due to the effect of two recesses on draw-in groove 5, so now four general cam 2 are cylinder deactivation state, and two spline cams 3 still normally work, namely six cylinders become two cylinders.
embodiment three
This six cylinder engine camshaft mechanism comprises a camshaft 1 and six cams, and described six cams are three general cam 2 and three spline cams 3.Wherein, be fixing assembly connection between general cam 2 and camshaft 1, between spline cam 3 and camshaft 1, realize sliding axially assembly connection by spline 4.Be provided with draw-in groove 5 at the side of camshaft 1, described draw-in groove 5 has three recesses, and described three recesses are corresponding with the protuberance of three spline cams 3 respectively, and on draw-in groove 5, the position of three recesses is corresponding with valve.
Motor not cylinder deactivation time, three general cam 2 and three spline cams 3 all corresponding with valve and in normal working.When needs cylinder deactivation, control camshaft 1 or the segment distance that moves right left, this segment distance can make three general cam 2 leave corresponding valve, meanwhile, three spline cams 3 slide axially relative to the spline 4 on camshaft 1 and make three spline cams 3 still be controlled on the position corresponding with valve due to the effect of three recesses on draw-in groove 5, so now three general cam 2 are cylinder deactivation state, and three spline cams 3 still normally work, and namely six cylinders become three cylinders.
