Description
Technical field
The present invention relates to a kind of control devices, are used especially for the device that control engine valve is in close state.
Background technique
Cylinder deactivation oil-break (becoming discharge capacity) is the technology that can effectively realize engine energy-saving emission reduction.To realize that cylinder deactivation is disconnected
Oil, on the one hand needs the fuel feeding of cut-off parts cylinder, on the other hand needs the valve for cutting off stopped the supple of gas or steam cylinder control that valve is made to be in normal
Closed state.The valve control for wherein cutting off stopped the supple of gas or steam cylinder makes valve be in the difficult point that normally off is the technology, existing valve control
Disconnecting device processed, structure is complicated, at high cost.
Summary of the invention
Disconnecting device is controlled for existing valve, structure is complicated, problem at high cost, proposes that one kind can be cut as needed
The device of the valve control of disconnected partial cylinders, serves cylinder deactivation oil-break technology.
The present invention is by rocker arm principal arm, rocker arm swing arm, priming lever spring, guiding bar, pin shaft a, pin shaft b, main pin, valve branch
Plate, electromagnet, electromagnet support, cushion block, pad bearing, control module composition.It is characterized in that: rocker arm principal arm and rocker arm swing arm are cut with scissors
It is connected together, guiding bar one end is hinged on rocker arm swing arm, and the guiding groove in the middle part of guiding bar covers on pin shaft a, and pin shaft a is mounted on
On pin hole a on rocker arm principal arm, priming lever spring covers in guiding bar, priming lever spring be mounted on rocker arm principal arm and rocker arm swing arm it
Between, priming lever spring has certain pretightning force after installing, power needed for which is greater than valve opening, rocker arm swing arm is pressed in valve
On supporting plate, valve supporting plate is pressed on valve, respectively installs a pad bearing in the cylinder head of valve front and rear sides, on the left of valve
Electromagnet support is installed, electromagnet is mounted on electromagnet support, and electromagnet can drive Y shape fork left and right to move in cylinder head
Dynamic, Y shape fork end is equipped with cushion block.
When tappet driving rocker arm rotates counterclockwise, since the pretightning force of priming lever spring is greater than the power of valve opening, rocker arm is dynamic
(or rotation very little angle) is not rotated between arm and rocker arm principal arm, rocker arm swing arm can open valve, and valve works normally.When
When valve is in the completely closed state, for valve supporting plate by valve top to extreme higher position, control module, which issues instruction, keeps electromagnet dynamic
Make, driving Y shape fork drives cushion block to be moved between valve supporting plate and pad bearing, due to cushion block, valve supporting plate and pad bearing
Supporting role, valve can not be by under rocking arm for pressing, and the support force of valve supporting plate is more than priming lever spring bullet during rocker arm pushes
Power, priming lever spring compressive deformation, rocker arm swing arm is rotated clockwise around main pin relative to rocker arm principal arm and is tilted, to realize gas
Door is fail to open, while guaranteeing that machine components are not damaged.When needing valve to work normally, electromagnet counteragent, Y shape are enabled
Fork drives cushion block to withdraw between valve supporting plate and cushion block supporting plate, and cushion block no longer hinders moving up and down for valve and valve supporting plate,
Valve can be normally-open.
