Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
The specific embodiment of the anti-canning cart tipple of flexible posture as Figure 1-Figure 4, canning cart include wheel hub 11,
Chassis 2 and the tank bucket 1 on chassis 2 is supported on by support column 10, tank bucket 1, which is generally used to contain, transports liquid.Liquid in tank bucket 1
It can not often fill with, in canning cart turning or inconsistent wheel hub 11 height in two sides, canning cart has rollover speed Vx, whole
Line between the center and wheel hub 11 of a canning cart and horizontal plane form an angle of heel θ, when to reach rollover critical for angle of heel
At 90 ° of angle, canning cart will turn on one's side.The anti-canning cart tipple of the embodiment of the present invention includes: air bag component 3 and stretches
Contracting frame component 4.
Referring to figures 1-3, air bag component 3 is filled between the liquid upper surface in tank bucket 1 and tank bucket 1, and air bag component 3 wraps
Utricule 31, the gas generator being arranged in inside utricule 31 32 and the fixed block 33 for being fixed on 31 upper surface of utricule are included, it is fixed
Block 33 and the inner surface on 1 top of tank bucket are fixed；Gas generator 32 is used to inflated with nitrogen in utricule 31 or will be in utricule 31
Nitrogen extraction, gas generator 32 include seal box 321, the liquid nitrogen 322 being stored in seal box 321, for what is be evacuated
Inflator 323 and the valve body 324 being connected between inflator 323 and liquid nitrogen 323, as shown in fig. 6, there is rollover in canning cart
When speed Vx, due to being full of nitrogen in utricule 31, and utricule 31 is fixed on the inner wall of tank bucket 1 by fixed block 33, air bag group
Part 3 is able to suppress the inclination of liquid upper surface, guarantees the center of gravity of canning cart still on the central axis of car body, without occurring partially
It moves, in order to guarantee the inclination of control liquid upper surface that air bag can be strong, is full of nitrogen, pressure in utricule 31 inside utricule 31
Answer > 200kpa.
As shown in figure 4, expansion bracket component 4 includes: inner arm 41, outer arm 42, the first telescopic rod 43, the second telescopic rod 44 and branch
Support wheel 45；The inner end of inner arm 41 is hinged on chassis 2, and outer end and the inner end of outer arm 42 are hinged；The outer end of outer arm 42 and support wheel
45 are fixedly connected；One end of first telescopic rod 43 and support column 10 are hinged, and the other end is hinged on the middle part of inner arm 41；Second is flexible
One end of bar 44 is hinged on the middle part of inner arm 41, and the other end is hinged on the middle part of outer arm 42, passes through the first telescopic rod 43 and second
The flexible adjustment support wheel 45 of telescopic rod 44 rises or landing.
Fig. 5 is state diagram of canning cart when with tipping speed Vx in the prior art, it can be seen that due to being tumbled
The influence of speed, the upper surface run-off the straight of the liquid in tank bucket 1 with respect to the horizontal plane have certain inclination angle, so that whole
The central axis of the deviation of gravity center car body of vehicle has angle of heel θ1。
The embodiment of the present invention and Fig. 5 in Fig. 6 compare, and the angle of heel in Fig. 6 is θ2, it can be seen that when canning cart has
When identical rollover speed Vx, θ2< θ1.In conjunction with Fig. 7 as can be seen that canning cart for the prior art, when rollover speed is V1
When, canning cart will tumble；And for the canning cart of the embodiment of the present invention, when rollover speed is V2When, it can just tumble, wherein V1
< V2。
As shown in figure 8, there are three working conditions for expansion bracket component 4: contraction state, extended state and locking state work as vapour
When vehicle straight-line travelling, tipping speed Vx< V2When, be in contraction state, support wheel not with ground face contact, the first telescopic rod 43 and the
Two telescopic rods, 44 pressure P < P1；Work as Vx> V2When, it is in extended state, 44 pressure P of the first telescopic rod 43 and the second telescopic rod1<
P < P2；When extended state reaches the limit of position, that is to say, that after support wheel 45 and ground face contact, the first of expansion bracket component 4 stretches
Contracting bar 43 and the second telescopic rod 44 are locked, are now in locking state, 44 pressure P=of the first telescopic rod 43 and the second telescopic rod
P2.The first telescopic rod 43 and the second telescopic rod 44 work at the same time when expansion bracket component 4 works, and inner arm 41 and outer arm 42 is driven to stretch
Support wheel 45 and ground face contact are played increase wheelspan, the work of reduction mass center to roll center A point straight line and ground angle theta by exhibition
With preventing from turning on one's side.Outer arm 44 is connect with support wheel 45 by bearing.The expansion bracket component 4 is relative to canning cart bilateral symmetry
Arrangement prevents canning cart left-leaning and Right deviation.
The anti-canning cart rollover prevention system of the flexible posture of the embodiment of the present invention as shown in Figure 9, including being mounted on canning cart
Steering wheel angle sensor 6, the wheel speed sensors 7 being mounted on the wheel hub 11 of canning cart on steering wheel, the control ECU that turns on one's side are mono-
Member 5, gas generator 32, the first telescopic rod driver 8, the second telescopic rod driver 12 and brake apparatus 9；Wheel speed sensors
7 and steering wheel angle sensor 6 by running car speed and corner parameter be sent to rollover control ECU unit 5, rollover control
ECU unit 5 processed calculates analysis and determines whether to turn on one's side, if reaching rollover threshold, i.e., laterally energy We+Wp > mgh, wherein
We is the lateral kinetic energy of vehicle, and Wp is the vertical gravitional force of vehicle, and mgh is that vehicle has when vehicle reaches rollover critical point θ=90 °
Vertical gravitional force, then the first telescopic rod driver 8 and the second telescopic rod driver 12 are sent commands to, to respectively drive
One telescopic rod 43 and the second telescopic rod 44 become extended state by contraction state, eventually arrive at locking state, play increase wheelspan
The effect of angle of heel is reduced, while controlling brake apparatus 9 and carrying out braking deceleration.
It should be appreciated that described above, the specific embodiments are only for explaining the present invention, is not intended to limit the present invention.By
The obvious changes or variations that spirit of the invention is extended out are still in the protection scope of this invention.
