Description
Technical field
The present invention relates to a kind of Intaker controller of diesel engine, be specifically related to a kind of air inlet break of Electronic control.
Background technique
At present, what generally adopt on a diesel engine is that high pressure oil pump fuel feeding starts, runs, and rely on external force to pull the shutdown handle on high pressure oil pump to carry out oil-break, parking, this mode is simple to operate easy to use.A period of time or fuel feed pump plunger corrosion but if diesel engine has been stopped using, stuck, during startup, just easily there is hypervelocity, driving phenomenon.In this case relying on external force to pull the shutdown handle on high pressure oil pump to stop and cannot realize, can only be adopt the method disconnecting in-line, blocking suction port or relief opening that diesel engine is stopped.Although diesel engine also can stop because of oil-break after disconnecting in-line, the time, longer harm was larger; And adopt the exhaust brake of blocking relief opening because delivery temperature is higher, also higher to the material requirements used, therefore high, the cost of cost is large, not easily accept by user.
Summary of the invention
The object of this invention is to provide a kind of when hypervelocity, driving phenomenon appear in diesel engine, can fast blocking diesel engine intake mouth electric type air inlet brake that diesel engine is stopped.
The present invention adopts following technological scheme: a kind of electric type air inlet brake, comprise casing, casing have the air outlet being respectively used to be communicated with the suction tude of diesel engine and the suction port be communicated with the outlet pipe of air-strainer, be provided with in casing for opening and closing suction port valve mechanism and control the control mechanism of valve mechanism work, the door-hinge that described valve mechanism comprises above by air outlet rotates the door-plate with open position and closed position be assemblied in casing, door-plate be positioned at door-hinge two side portions be respectively pushing tow section and when closed position and air outlet seal the closed section that establishing closes, described control mechanism comprises and is slidedly assemblied in the slide block coordinated with the pushing tow section block of door-plate when open position in casing and the drive unit driving slide block movement, described drive unit comprises electromagnet, electromagnet comprises the coil winding and the iron core be assemblied in coil winding that slides axially that axis extends along the longitudinal direction, the front end of iron core stretches out coil winding and extension and slide block are connected, be provided with between slide block and casing and depart from when door-plate moves the elastic component of slide block applying towards door-plate active force at slide block.
Described electromagnet is two that are arranged symmetrically in the slide block left and right sides, and described slide block is connected by connecting arm-tie and two iron cores, the intermediate section of connection arm-tie and slide block is connected, two ends are connected with two iron cores respectively.
Described air outlet and suction port lay respectively on the forward and backward end wall of casing, and the axis of described door-hinge extends in left-right direction, and described slide block is slidedly assemblied in casing along the longitudinal direction.
Described slide block is assemblied in casing by the sliding bar extended along the longitudinal direction, and described elastic component is the stage clip be sleeved on slide bar, the rear end inwall apical grafting of one end of stage clip and the rear end apical grafting of slide block, the other end and casing.
Described air outlet sleeve pipe is communicated with the suction tude of diesel engine, the front bulkhead outer wall that one end of described sleeve pipe is fixed on casing is communicated with air outlet, the inwall of end cap coincide sheathed cooperation with the suction tude outer wall of diesel engine, and internal surface of sleeve pipe offers annular groove, be filled with O RunddichtringO in annular groove.
Described suction port is communicated with the outlet pipe of air-strainer by end cap, the aft bulkhead outer wall that one end of described end cap is fixed on casing is communicated with suction port, the inwall of end cap coincide sheathed cooperation with the exhaust tube wall of air-strainer, and the ear end face of end cap has the annular gear edge extended internally, and is top-loaded with y-type seal ring between annular gear edge and casing.
Inner edge, described air outlet is stretched in casing.
The closed section of described door-plate seals establishing by ring-shaped rubber plate and described air outlet and closes, and described ring-shaped rubber plate is fixed on the closed section of door-plate.
Adopt the electric type air inlet brake of said structure, casing offers respectively the air outlet be communicated with the suction tude of diesel engine and the suction port be communicated with the outlet pipe of air-strainer, such air-strainer is communicated with diesel engine by casing, the door-plate of valve mechanism is rotated by door-hinge and is assemblied in casing, and the door-hinge two side portions that is positioned at of door-plate is respectively pushing tow section and seals with air outlet the closed section that establishing closes, door-plate and door-hinge is made to form leverage like this, the closed section of door-plate can rotate towards air outlet under self gravitation effect, thus close air outlet, the skid of control mechanism is assemblied in casing, when door-plate is in open position, slide block coordinates with the pushing tow section block of door-plate and can prevent the closed section of door-plate from closing air outlet, only after the energising of magnet spool winding, iron core band movable slider departs from door-plate and moves the closed section that just can realize door-plate and move towards air outlet, simultaneously when door-plate is in closed position, only after the power-off of magnet spool winding, under the active force of stage clip, slide block is moved towards door-plate, and the pushing tow section of pushing tow door-plate make door-plate get back to open position.Therefore, when there is hypervelocity, driving phenomenon in diesel engine, make slide block depart from door-plate by electromagnet energising and move the quick closure that both can realize air outlet, thus close diesel engine intake mouth, slide block is made to move the unlatching that can realize air outlet towards door-plate by electromagnet power-off, thus ensure that diesel engine normally works, the air inlet break of this structure adopts Electronic control, easy to install, reliability is high, in air inlet brake operation process, diesel engine and equipment thereof are not affected, simultaneously simple, the low cost of manufacture of structure.
