Principle of work of the present utility model is elaborated as follows:
Referring to shown in Figure 1, when the vehicle at full load, manual lifting is carried select switch 6 connect the 6a position, then the bearing interface 3g mouth of two automatically controlled solenoid directional control valves 3 is communicated with gas source interface 3e mouth, lifting interface 3h mouth is communicated with exhausr port 3f mouth, high pressure gas in the air tank 1 enter carrying air bag 11 by gas source interface 3e mouth, bearing interface 3g mouth, relay valve 2, the safe rapid release valve 8 of two automatically controlled solenoid directional control valves 3, gas in the Lifting air sac 12 is discharged by the exhausr port 3f of two automatically controlled solenoid directional control valves 3 simultaneously, and floating axle is in loaded state.
Referring to shown in Figure 2, when vehicle is unloaded, manual lifting is carried select switch 6 connect the 6b position, then the bearing interface 3g mouth of two automatically controlled solenoid directional control valves 3 is communicated with exhausr port 3f mouth, lifting interface 3h mouth is communicated with gas source interface 3e mouth, and the high pressure gas in the air tank 1 enter Lifting air sac 12 by gas source interface 3e mouth, the lifting interface 3h mouth of two automatically controlled solenoid directional control valves 3, simultaneously, gas in the carrying air bag 11 is discharged by safe rapid release valve 8, and floating axle is in the lifting state.
Referring to shown in Figure 3, when vehicle is unloaded, manual lifting carrying select switch 6 is positioned at 6a position (carrying position), automatically the 4a of lifting switch 4 end and 4b end are closed, normally closed relay 9 is connected, and the bearing interface 3g mouth of two automatically controlled solenoid directional control valves 3 is communicated with exhausr port 3f mouth, and lifting interface 3h mouth is communicated with gas source interface 3e mouth, system becomes " lifting " state, floating axle lifting automatically; After vehicle was fully loaded, lifting switch 4 disconnected automatically, and normally closed relay 9 disconnects, and the bearing interface 3g mouth of two automatically controlled solenoid directional control valves 3 is communicated with gas source interface 3e mouth, and lifting interface 3h mouth is communicated with exhausr port 3f mouth, and system recovers " carrying " state automatically.
The braking delivery port 5a mouth of shutoff valve 5 connects the output pressure of braking, compressed air brake cylinder mouth 5b mouth connects compressed air brake cylinder, when system is in the lifting state, high pressure gas are by the lifting interface 3h mouth of two automatically controlled solenoid directional control valves 3, enter the control of braking mouth 5c of shutoff valve 5, shutoff valve 5 cuts off the brake circuit of floating axle, even chaufeur enforcement this moment braking maneuver can not produce brake action yet, thereby reduces compressed-air actuated consumption; When system was in loaded state, the high pressure gas in the shutoff valve 5 were discharged by the exhausr port 3f mouth of two automatically controlled solenoid directional control valves 3, and the brake circuit of floating axle is reclosed, and chaufeur is implemented drg normal operation on the braking maneuver floating axle.
The automatic lifting switch 4 of function is carried in the band sense in the present embodiment, is to install dry-reed tube switch 17 additional to realize empty fully loaded indication on the cam 16 of original load sensing valve.Load sensing valve is a kind of device according to car load assignment system power.Dry-reed tube switch 17 is special keys of a kind of magnetosensitive, it is usually by two or three not only reed contacts of making of magnetic conduction but also conductive material, be encapsulated in the glass tube that is filled with unreactable gas (as nitrogen, helium etc.) or vacuum, the leaf end of the interior parallel encapsulation of pipe is overlapping in the glass tube, and leaves certain interval or be in contact with one another often opening or normally closed contact with the formation switch.
Principle of work: when car load reduces, because the elastic deformation of suspension, the load sensing valve and the interaxle that are installed on the vehicle frame are near apart from change, the cam 16 that elastic arm drives load sensing valve rotates, the permanent magnet 22 that is installed on the cam 16 rotates thereupon, when vehicle is unloaded, cam 16 forwards to and reaches ad-hoc location (as the idle position), permanent magnet 22 on the cam 16 is near the dry-reed tube switch 17 that is installed on the load sensing valve housing, perhaps make reed when magnetization by forming magnetic field behind the coil electricity above dry-reed tube switch 17, make the reed magnetization, the contact of reed can induce grade opposite magnetic pole of property, because pole polarity attracts each other mutually on the contrary, when the magnetic force that attracts surpasses the drag of reed, contact separately just can adhesive, and this moment, 4a connected with 4b, and dry-reed tube switch 17 is exported airborne signals; Otherwise when magnetic force was reduced to certain value, contact returned to initial condition again under the effect of reed drag, and 4a and 4b disconnect, and dry-reed tube switch 17 is output signal not.So just, finished the effect of a switch.
Referring to shown in Figure 4, one end of the fork 18 of load sensing valve is connected with in-to-in cam 16, when fork 18 motions, cam 16 rotates thereupon, the other end of fork 18 links to each other with rear axle case, the up-and-down movement along with the variable in distance in vehicle frame and workshop, back, load sensing valve rotates according to inner cam 16 and carries out brakig force distribution.This valve is installed on the automobile chassis frame, is connected with certain attachment point on the vehicle bridge by elastic arm.When cam 16 moves to 20 of the bottom dead points of idle position and fork, dry-reed tube switch 17 output airborne signals, the 4a of lifting switch 4 end is logical with the 4b termination automatically; When cam 16 moved between the top dead point 19 of idle position and fork, dry-reed tube switch 17 is output signal not, and the 4a of lifting switch 4 end disconnects with the 4b end automatically.
Referring to shown in Figure 5, because the elastic deformation of suspension, when unloaded, the distance of vehicle bridge and valve is maximum, and fork 18 is in extreme lower position.Load with automobile, this distance is dwindled, and fork 18 moves to fully loaded locality from zero load, is subjected to the cam 16 of fork 18 controls to make tappet 21 rise to corresponding load situation.If when fork 18 or elastic arm fracture, cam 16 self-returns make tappet 21 be in certain ad-hoc location, thereby have determined the semi-load of automobile or the function of fully loaded position.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
The content that is not described in detail in this specification sheets belongs to this area professional and technical personnel's known prior art.
