Abstract
The invention discloses an up-down moving device of a movable rod in the field of mechanical design. The up-down moving device comprises an intake valve, an exhaust valve, an air compressor, a turbine, a lever, a tappet, a volume cavity, a moving body, a connecting pipe and a spring, wherein the moving body is arranged in the volume cavity and is in sealing contact with the inner wall face of the volume cavity; the upper wall face of the volume cavity is provided with a circular hole; the lower end of the moving rod penetrates through a circular hole in the upper wall face of the volume cavity and then is fixedly connected with the upper wall face of the moving body; and the upper end of the moving rod is in contact with the lever. When pressure in an intake pipe of an engine is large, the moving body drives the moving rod to move downwards, and the lift of the intake valve is increased; and when the pressure in the intake pipe of the engine is small, the moving body drives the moving rod to move upwards, and the lift of the intake valve is decreased. The up-down moving device has the advantages of rational design and simple structure and is suitable for an engine valve lift variable system.

Traditional petrolic valve lift is fixing immutable, and namely the cam profile of camshaft only has a kind ofly, and this has just caused 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 is that design of cam contour line is that the balance of motor under full operating mode selected, consequently motor both can not get best high speed efficient, also can not get best low speed torque, but obtained best balanced performance under the full operating mode.The employing of lift range variable makes motor can both be met the valve lift of demand in high velocity and low velocity zone, thereby improves high engine speeds power and low speed torque.
Find through the retrieval to the 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 preferably the high and low rotating speed operating mode of motor.But its design needs special control structure, whole system complex structure.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of movement rod to move up and down device, valve lift can realize continuous variable, and does not need special control mechanism.
The present invention is achieved through the following technical solutions, the present invention includes: cylinder, piston, cylinder head, intake duct, air outlet flue, intake valve, exhaust valve, the compressor air inlet machine pipe, gas compressor, engine air inlet tube, turbine exhaust pipe, turbine, engine exhaust pipe, lever, tappet, connecting tube, cavity volume, moving body, movement rod and spring, piston is installed in the space that cylinder surrounds and with the internal face sealing of cylinder and contacts, the air outlet of intake duct, the suction port of air outlet flue all is connected with cylinder head, the lower end surface of intake valve, the lower end surface of exhaust valve is all in the firing chamber, the air inlet/outlet of gas compressor respectively with the air outlet of compressor air inlet machine pipe, the suction port of engine air inlet tube is connected, the air outlet of engine air inlet tube is connected with the suction port of intake duct, the air inlet/outlet of turbine respectively with the air outlet of engine exhaust pipe, the suction port of turbine exhaust pipe is connected, the suction port of engine exhaust pipe is connected with the air outlet of air outlet flue, the two ends of lever respectively with the upper end of intake valve, the upper end of tappet is connected, the cross section of cavity volume is rectangular, moving body is installed in the cavity volume and with the internal face sealing of cavity volume and contacts, the upper wall surface of cavity volume has a circular hole, the upper wall surface that the lower end of movement rod is passed behind the circular hole on the cavity volume upper wall surface with moving body is consolidated, circular-hole internal-wall sealing on movement rod and the cavity volume upper wall surface contacts, the upper end of movement rod contacts with lever, the two ends of connecting tube respectively with the upper wall surface of cavity volume, engine air inlet tube is connected, and the lower wall surface of moving body is connected with the lower wall surface of cavity volume by spring.
In the present invention, moving body and movement rod are consolidated, and moving body can move up and down in cavity volume, and movement rod can followed moving body and moved up and down, and the operation angle of lever can change along with moving up and down of movement rod.At high-speed working condition, the engine charge overpressure is higher, and the cavity volume internal pressure of moving body top is also higher, and moving body drives movement rod and moves down also Compress Spring, thereby makes the intake valve lift become large.In the low speed operating mode, the engine charge overpressure is lower, and the cavity volume internal pressure of moving body top is also lower, and under the elastic reaction of spring, moving body drives movement rod and moves up, thereby the intake valve lift is diminished.
Compared with prior art, the present invention has following beneficial effect and is: the present invention is reasonable in design, and is simple in structure, can realize the continuous variable of valve lift, do not need again special control mechanism.
