Abstract
The utility model relates to a negative pressure control device for vehicles, particularly a control device used for special-purpose vehicles, which utilizes the negative pressure generated by an air inlet pipe when the engine of a vehicle works to drive a cylinder via vacuum to drive an actuating mechanism and achieve the remote transmission control of the vehicle which has no compressed air source and hydraulic power source. The utility model has the advantages of simple structure and reliable operation, and is not only suitable for the remote transmission control of special vehicles such as tank vehicles, discharging vehicles, self-discharging vehicles, etc., but also suitable for the remote transmission control of common vehicles, such as the closing of the vehicle door, the opening of the vehicle window, etc.
Description
The utility model relates to a kind of automobile negative pressure control apparatus, particularly special-use vehicle negative pressure control apparatus.
Existing controller for vehicle has mechanical type, vapour-pressure type and fluid pressure type, and the former structure complexity, the latter need be equipped with air compressor or hydraulic oil pump on automobile.
Task of the present utility model provides a kind of simple in structure, and reliable operation both be not equipped with air compressor on the automobile, be not equipped with the automobile negative pressure control apparatus of hydraulic oil pump again.
Solution of the present utility model is: with relay (1), two-position switch (2), two-bit triplet electromagnetic valve (3), vacuum driven cylinder (4), check valve (13), gas tank (14) is formed a control loop, and vacuum driven cylinder (4) is linked to each other with engine air inlet tube, the negative pressure that engine air inlet tube produces when utilizing engine operation drives the piston (9) in the vacuum driven cylinder (4), then by push rod (10) pushing executing mechanism.During work, two-position switch (2) pushes the position of A, connects the power supply of two-position three way magnetic valve (3).Vacuum driven cylinder (4) and engine air inlet tube are communicated, under the engine air inlet tube suction function, form negative pressure in the vacuum driven cylinder (4), under the bar pressure effect, piston (9) action gets final product pushing executing mechanism by push rod (10).Check valve (13), gas tank (14) guarantee that the negative pressure of control loop is constant in the time of guaranteeing fluctuation of engine air inlet tube negative pressure or parking.
The utility model automobile negative pressure control apparatus, simple in structure, reliable operation can realize negative pressure teletransmission manipulation on the automobile of non-compressed air source and hydraulic efficiency gear.Of many uses, the teletransmission that is not only applicable to special-uses vehicle such as motor tank tuck, dumping car, blowdown car is controlled, and also is applicable to general automobile door closing, the teletransmission control that vehicle window is opened.
The utility model will be illustrated more clearly in from the accompanying drawing of the following example:
Fig. 1, the utility model Liquid Tank Motor Vehicle vacuum control system figure.
Fig. 2, the utility model Liquid Tank Motor Vehicle vacuum driven cylinder cutaway view.
Fig. 3, the utility model Liquid Tank Motor Vehicle gas control two position four-way valve cutaway views.
Liquid Tank Motor Vehicle shown in Figure 1 pneumatic control system figure.Vacuum driven cylinder (4) links to each other with engine air inlet tube with (6) by two-bit triplet electromagnetic valve (3) respectively with gas control two position four-way valves (7).During work, toggle switch (2) is connected the power supply of two-position three way magnetic valve (3) to the position of A, and vacuum driven cylinder (4) and engine air inlet tube are communicated.Under the engine air inlet tube suction function, form negative pressure in the cylinder of vacuum driven cylinder (4), under the effect of bar pressure, piston (9) action promotes the propulsion box shift fork action of putting into gear by push rod (10), and propulsion box gear and gearbox gear are meshed.The propulsion box outputting power extracts in the flow container of liquid to the automobile vacuum pump running.When liquid reaches certain position in the flow container, by electronic alarm and normally closed relay (1) action, cut off the electric current of two-position three way magnetic valve (3), electromagnetic valve resets, cut off the path of vacuum driven cylinder (4) with engine air inlet tube, vacuum driven cylinder (4) communicates with atmosphere, under spring (8) effect, piston (9) resets, push rod (10) drives the shift fork of putting into gear, and propulsion box gear and gearbox gear are thrown off, and the vacuum pump propulsion source cuts off, running stops, and extracts liquid and stops.
When needs were discharged on the automobile in the flow container liquid, switch (5) closed, and two-position switch (2) pushes the position of B.Connect the power supply of two-bit triplet electromagnetic valve (6), the cylinder of two-position four-way valve (7) is communicated with engine air inlet tube, form vacuum in the cylinder, cylinder piston (11) drives valve stamen (12) and moves under the bar pressure effect, change the path of vacuum pump import and export and tank body interface, vacuum pump outlet and flow container are connected.Because switch (2) has pushed the position of B, the power supply of two-position three way magnetic valve (3) is connected again, vacuum driven cylinder (4) is communicated with engine air inlet tube, propulsion box is outputting power again, vacuum pump output pressurized air is in jar, under gas pressure, pot liquid is by outside the outlet drain tank.
Claims (1)
- The automobile negative pressure control apparatus, special-use vehicle negative pressure control apparatus particularly, relay (1) is arranged, two-position switch (2), two-bit triplet electromagnetic valve (3) and vacuum driven cylinder (4), check valve (13), gas tank (14) is formed control loop, it is characterized in that the negative pressure interface in this loop links to each other with engine air inlet tube.
