Description
Technical field
Automobile hedging security technology area of the present invention, more particularly to a kind of deflation for avoiding system of mechanically blowing out
Valve.
Background technology
This technology belongs to automobile active safety system, suitable for any motor vehicles.Blown out in running car phenomenon,
Serious traffic accidents will be caused, because blowing out is occurred in high-speed cruising, especially deflecting roller occurs
To blow out, the disequilibrium due to body sway, left and right turn wheel rolling radius and tire differ larger with the auxiliary force on ground, this
When automobile almost lose course changing control ability, serious sideslip occurs, if forced brake will aggravate sideslip, if force amendment side
To, will increase automobile overturning possibility.At present, the correlation technique on active hedging of blowing out is less, such as patent application is public
After the A of cloth CN 103847438, data of publication of application 2014.06.11 Chinese invention patent disclose a kind of vehicle flat tire,
Avoid occurring the safety device of accident, bag Chinese juniper：Wheel hub, tire, wheel hub outer ring are provided with charging port base, set in charging port base
Have and filler body elastic caoutchouc ball is provided with the tyre cavity described in leak-stopping tapered plug, it utilizes elastic rubber when automobile flat tire
The mode that glueballs is supported ensures safety, but if such structure is too small if the gap stayed between elastic ball and tire
The normal work of tire can be influenceed, gap is excessive, and the air pressure that can not have effect, especially tire is because vehicle, personnel are practised
Used change, so its effect is not good enough.
So the temporary decrease danger measure of present automotive tire burst this respect accident is done using driving technology
In advance, or increase is blown out the rolling radius of rear wheel.The former needs seasoned calm human pilot to obtain limited effectiveness,
The latter has the similar techniques such as so-called trouble-proof tire to increase the vehicle wheel roll radius after blowing out, and only makes on very limited vehicle
With, and can only finite reduction degree of danger.
The content of the invention
It is an object of the invention to provide a kind of vent valve for avoiding system of mechanically blowing out, its deflation speed is fast, effect
Fruit is good, and in avoiding system of blowing out, whole hedging process is not required to human intervention, and human pilot only needs normal control direction and just
Often slow down, ensure that vehicle and the safety of personnel.
The solve the above problems technical scheme of use of the present invention is：For the vent valve for avoiding system of mechanically blowing out, institute
Stating vent valve includes deflation valve body, the deflation valve element that gap cooperation is plugged in the deflation valve body, is sleeved on the vent valve

To connect with pipeline, when there is hydraulic oil to enter in the oil cylinder chamber of cylinder body, promote piston movement, and then cause extension rod movement,
This when, guide pad move in axially directed groove, play a part of guiding；The squeeze fuel tank is full of including inside
The thin-wall box body of hydraulic oil, the hydraulic fluid port being located on the thin-wall box body；Thin-wall box body is that wall thickness is relatively thin, toughness is higher, easy statue
The copper vessel for deforming and being not easily broken, wall thickness determine according to the actual requirements, such as 1mm, 2mm etc..
Below, the operation principle of the lower present invention is described with reference to accompanying drawing, a vent valve 2 is both provided with every side wheel,
The deflation valve body 201 of vent valve 2 is screwed onto on wheel hub, and corresponding screwed hole is offered on wheel hub, meanwhile, in every side wheel position
Hydraulic pressure trigger mechanism, squeeze fuel tank are designed with, hydraulic pressure trigger mechanism is arranged on knuckle peak, the hydraulic pressure trigger mechanism
Connected by pipeline with the squeeze fuel tank at respective side wheel steering section minimum point.
As shown in Fig. 2 after certain single wheel is blown out, gas is released at once in tire, and the height of tire declines,
When vent valve 2 goes to minimum point, fixed, the deflation being located in deflation valve body 201 because deflation valve body 201 is spirally connected
Valve element 202 will be come by ground ejection, during wheel hub is rotated further, will be squeezed with discontiguous hydraulic pressure during original rotation
Case contact is pressed oil, thin-wall box body is extruded, bringing it about plastic deformation could be by, is full of fluid when in thin-wall box body
, so in the deformation of thin-wall box body, can force the fluid of the inside by the passage body of hedging oil gear and and its
The pipeline of connection is expressed at the hydraulic pressure trigger mechanism of opposite side wheel, and fluid enters in cylinder body so that is located at the oil cylinder
Piston in body is protruding, the piston of stretching when the vent valve 2 on the side wheel goes to peak, transverse slat on piston and
Collision arm 204 is in contact, and then is collided, because collision arm 204 is relatively-stationary with deflation valve element 202, this will be collided
Arm 204 will drive deflation valve element 202 to turn an angle, and then tear the sealing shroud of thermoplastic material, release deflation valve body 201
In deflation valve element 202 between sealing state so that the gases at high pressure in tire are discharged by deflation valve element 202, reach flat
The effect of weighing apparatus both sides tire, prevent direction of traffic deflection, ensure vehicle safety.Further, the presence of compression spring, when
During wheel high-speed rotation, the compression spring is by collision arm centrifugal action compression, and collision arm is close to wheel hub, when its movement
After to certain position and the transverse slat that is connected on piston is same or during close to sustained height, and both collide, and transverse slat can not
Rotate, and collision arm is forced to rotate an angle, completes to open the action of vent valve.
Embodiments of the present invention are explained in detail above in conjunction with accompanying drawing, but the invention is not restricted to above-mentioned embodiment party
Formula, can also be before present inventive concept not be departed from the technical field those of ordinary skill possessed knowledge
Put and make various modifications.These be all without creative modification, as long as in scope of the presently claimed invention all by
To the protection of Patent Law.
