Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to the present invention
Embodiment is described in further detail.
As it is shown in figure 1, embodiments provide a kind of VVT, described changeable air valve
Timing system includes cam 1, outer steel pipe 2, interior steel pipe 3 and phase-regulating mechanism 4, and cam 1 is fixedly installed
Outside on steel pipe 2, it is internal that interior steel pipe 3 and phase-regulating mechanism 4 are sequentially arranged steel pipe 2 outside, interior steel pipe 3
It is rotationally connected with outer steel pipe 2 so that interior steel pipe 3 can rotate in steel pipe 2 outside, phase-regulating mechanism 4
With outer steel pipe 2 being in axial sliding connection along outer steel pipe 2, and outer steel pipe 2 and phase-regulating mechanism 4 circumference is quiet
Only so that relative can only slide between phase-regulating mechanism 4 with outer steel pipe 2 and cannot relatively rotate, such as,
Slide rail or chute can be set on steel pipe 2 outside, and arrange corresponding with slide rail on phase-regulating mechanism 4
Pulley or the slide block corresponding with chute, be phase-regulating mechanism 4 sliding axially along outer steel pipe 2, Qi Zhong
When interior steel pipe 3 is not connected with phase-regulating mechanism 4, interior steel pipe 3 steel pipe 2 outside is internal to be rotated freely,
During work, make the inside steel pipe 3 of regulation axle 41 in phase-regulating mechanism 4 move by external force and with interior steel pipe
3 connect so that interior steel pipe 3 drives phase-regulating mechanism 4, outer steel pipe 2, cam 1 together while rotating
Rotating, the valve on electromotor is backed down in rotation process by cam 1.Wherein by steel pipe 3 in controlling
Rotating speed also can limit, by phase-regulating mechanism 4, the angle that interior steel pipe 3 rotates, can be effectively to valve
The folding time be adjusted with folding angle.
It should be understood that when making the inside steel pipe 3 of phase-regulating mechanism 4 move, air pressure, hydraulic pressure etc. fill
Putting all can be as the power making phase-regulating mechanism 4 move.
The present invention by arranging outer steel pipe 2, the interior steel pipe 3 that can rotate in steel pipe 2 outside, can steel outside
The internal phase-regulating mechanism in axial sliding 4 along outer steel pipe 2 of pipe 2 and be fixed on outer steel pipe 2 convex
Wheel 1, can be connected with phase-regulating mechanism 4 by making interior steel pipe 3 so that interior steel pipe 3 drives phase adjusted
