Explanation, it is therefore an objective to those skilled in the art be helped to have more complete, accurate and deep reason to design of the invention, technical solution
Solution, and facilitate its implementation.
As shown in Figure 1, the enclosure space (i.e. inside tires) being made of inside box tyre and rim, the outside of box
It is atmosphere (i.e. outside tires), manostat is connected in the enclosure space of tyre and rim composition；Manostat is by adding
Press pump 1, regulating valve 2, control valve 3 and snorkel 51 form, these components are connected with each other by gas circuit and are connected with wheel rim 71, lead to
Tracheae 51 is communicated with outside atmosphere；
When tire pressure within the set range, regulating valve 2 closes snorkel 51, inside tires and external isolation；

Section this gas circuit of valve 2 is connected to inside tires, the inertia power drive that force (forcing) pump 1 is generated by tire motion, by outside tires atmosphere
It is pumped into inside tires；
When tire pressure is higher, as shown in figure 3, control valve 3 drive regulating valve 2, by snorkel 51 to regulating valve 2 this
Gas circuit is connected to inside tires, and inside tires air flows out to outside atmosphere.
Specifically,
Embodiment one,
As shown in Fig. 4 to Figure 11, manostat is made of force (forcing) pump 1, regulating valve 2, control valve 3, snorkel 51, is also wrapped
Include bracket 6 and filter core 52.
As shown in Figure 5 and Figure 6, bracket 6 is connected in 71 circumferential surface of wheel rim, and 51 center hollow of snorkel runs through 6 He of bracket
The periphery of wheel rim 71 is communicated with outside tires；Snorkel 51 is in hook solid, and snorkel 51 is radial to wheel rim 71 from wheel rim 71
Core wheel direction is again curved to the core wheel direction away from wheel rim 71 after stretching out.When tire is in ponding road traveling, snorkel 51 is by vehicle
It is immersed in water at wheel rotation to ground connection, but the effect of the centrifugal force due to wheel rotation generation, the ponding of 51 oral area of snorkel
It can be thrown away by the centrifugal force in the core wheel direction away from wheel rim 71, enter inside snorkel 51 so as to avoid ponding, as a same reason,
Impurity soil lamp foreign matter can also be thrown away when wheel rotates by centrifugal force, will not be entered inside snorkel 51；When tire is relatively deep
Ponding road surface it is static when, while snorkel 51 is located at the ground connection of tire, and at this moment snorkel 51 can be flooded by ponding, but because
It not being rotated for tire, there is no inertia power drives to be evacuated for the force (forcing) pump 1 in tire pressure stabilizer, and snorkel 51 is simultaneously obstructed, and because
51 internal diameter of snorkel is smaller and oral area downward, water preferably at most accumulates since there are surface tension to hardly enter inside snorkel 51

When the revocation of the inertia force of demand, piston 12 is arranged on the effect of the reset spring 13 between piston 12 and high-voltage end, piston 12
It is moved toward the direction far from high-voltage end, i.e., piston 12 is toward low pressure end motion, while high-voltage end sucks air；For the pump of high-voltage end
Pressure-air out does not flow into atmosphere, and air cannot be sucked out of tire also for high-voltage end, needs to be arranged two check valves,
A second one-way valve 42 is sealed between 1 high-voltage end of force (forcing) pump and regulating valve 2, so that air is only capable of from 1 high-voltage end stream of force (forcing) pump
Enter regulating valve 2,；First check valve 41 is sealed between 1 high-voltage end of force (forcing) pump and snorkel 51, so that air is only capable of from ventilation
Pipe 51 flows into 1 high-voltage end of force (forcing) pump；In order to which piston 12 is smooth in 11 internal motion of pump case, the low-pressure end of force (forcing) pump 1 is wanted and atmosphere
It communicates, i.e., the low-pressure end of force (forcing) pump 1 is connect with snorkel 51, and the low-pressure end of such force (forcing) pump 1 will not be because of the mobile formation of piston
Negative pressure and hinder piston 12 move；It should be noted that when as long as inertia force is acted on piston 12, piston 12 will move or
Has the tendency that movement, this depends on whether regulating valve 2 is connected to 1 high-voltage end of force (forcing) pump with inside tires.
As shown in fig. 7, inertia force described above is since the braking of wheel generates, by force (forcing) pump 1 along vehicle wheel rotation
The tangential placement of the tangential placement in direction, the i.e. axis of piston 12 along vehicle wheel rotation direction.Quality and section about piston 12

Effect is slowed down, and the direction of motion setting of piston 12 rotates the wheel separate as far as possible tangential parallel, piston 12 is arranged with wheel
The core wheel of rim 71, deceleration when then braking further away from the core wheel of wheel rim 71 is more considerable, when core wheel of the piston 12 apart from wheel rim 71
Distance it is equal with the rolling radius of wheel when, then the braking deceleration of piston 12 is equal with vehicle deceleration.Based on above-mentioned point
Analysis, 12 mass value 60g of piston, 12 deceleration of piston is consistent with vehicle deceleration, value 5m/s2 (braking of moderate strength),
12 diameter 1mm of piston, then can produce pressure is 382Kpa (absolute pressure), and the general value of tire pressure is 331kpa (phase
To pressure 230kpa+ atmospheric pressure 101kpa), by multiple above-mentioned damped condition, the supplement to tire pressure may be implemented.It needs
Illustrate, when emergency braking, with vehicle speed per hour 100km/h calculating, wheel can the locking in 0.3 second, hub reduction degree is high
Up to 92.7m/s2, then above-mentioned specification piston 12 can produce the pressure of 7085kpa, so, the design of the specification of piston 12 can take
The range of value is larger, is specifically dependent upon the strong matching relationship of the frequency, 12 discharge capacity of piston and pump air pressure of the appearance of inertia force operating condition, this
