Background technique
Traditional petrolic valve lift is fixing immutable, and namely the cam profile of camshaft only has one, and this just causes this lift can not make motor all obtain good response in high velocity and low velocity zone.The valve lift of conventional gasoline machine motor and design of cam contour line select the balance of motor under full working scope, consequently motor both can not get best high speed efficiency, also can not get best low speed torque, but best balanced performance under obtaining full working scope.The employing of lift range variable, makes motor can be met the valve lift of demand in high velocity and low velocity zone, thus improves high engine speeds power and low speed torque.
Through finding the retrieval of prior art document, China Patent No. application number 200910190522.1, patent name: a kind of hydraulic valve mechanism of lift range variable, this patented technology provides a kind of device of variable valve lift, can take into account the high and low rotating speed operating mode of motor preferably.But its design is the hydraulic mechanism utilized, and very high to sealing requirements, poorly sealed words easily cause fluid seepage; And there is certain compressibility due to liquid, the speed of response of valve lift change has certain retardance.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of moving body horizontal moving tappet gear, the speed of response that valve lift can be made to change is very fast.
The present invention is achieved through the following technical solutions, the present invention includes: cylinder, cylinder head, suction tude, intake duct, intake valve, exhaust valve, air outlet flue, outlet pipe, pillar, lever, tappet epimere, tappet hypomere, cavity volume, moving body, run through pipe, moving block, first connecting tube and the second connecting tube, the air outlet of intake duct, the suction port of air outlet flue is arranged in cylinder head, the air outlet of suction tude is connected with the suction port of intake duct, the suction port of outlet pipe is connected with the air outlet of air outlet flue, the upper end of intake valve is connected with one end of lever, pillar is arranged in the neutral position of lever, moving body to be arranged in cavity volume and to seal with the internal face of cavity volume and contacts, run through two walls up and down that pipe runs through moving body, moving block is arranged on to run through in pipe and seal with the internal face running through pipe and contacts, the lower end surface of moving block is plane, the upper-end surface of moving block is inclined-plane, the upper end of tappet epimere is connected with the other end of lever, the lower end of tappet epimere through cavity volume upper wall surface and stretch into and run through in pipe, the lower end surface of tappet epimere seals with the upper-end surface of moving block and contacts, the upper end of tappet hypomere through cavity volume lower wall surface and stretch into and run through in pipe, the upper-end surface of tappet hypomere seals with the lower end surface of moving block and contacts, the cross section of cavity volume is rectangular, running through pipe is uniform section pipe, the two ends of the first connecting tube respectively with suction tude, the left wall of cavity volume is connected, the two ends of the second connecting tube respectively with outlet pipe, the right wall of cavity volume is connected.
In the present invention, moving body and moving block can move left and right in cavity volume, and moving block also can followed by tappet epimere and move up and down together with tappet hypomere running through in pipe.When being less than the pressure in outlet pipe when the pressure in suction tude, moving body is moved to the left under the effect of pressure reduction, then moving block is also moved to the left simultaneously, the lower end surface of tappet epimere and the upper-end surface relative sliding of moving block, tappet epimere moves down, thus the lift of intake valve is diminished.When being greater than the pressure in outlet pipe when the pressure in suction tude, moving body moves right under the effect of pressure reduction, and moving block also moves right simultaneously, the lower end surface of tappet epimere and the upper-end surface relative sliding of moving block, tappet epimere moves up, thus makes the lift of intake valve become large.
Compared with prior art, the present invention has following beneficial effect and is: the present invention is reasonable in design, and structure is simple, can realize the continuous variable of valve lift, and the speed of response that valve lift can be made again to change is very fast, and does not need special control mechanism.
