Abstract
A pair of devices are installed on a wheel inside a tire. Each device has a vacuum chamber, a hyper-pressure chamber and an alternator that are driven by the pressing force of the ground when the tire rolls. An electronic controller gathers data from various sensors, processes the data, controls all parts properly and wirelessly communicates with the central unit in the room of a vehicle. A driver can monitor the states of all the tires and set predefined modes related to the tire pressure through that one. The vacuum chamber's swift return can let the tire deflate instantaneously and the hyper-pressure chamber's rapid spout can let the tire inflate instantaneously. Accordingly, not only human intervention to change the tire pressure is not needed for the life time of the tire, but also the tire pressure instantaneously optimizes for the load and the speed of a vehicle or to best cope with an abrupt exterior situation.
Description
Background technology
The tire tolerance of all vehicles is fixed to some numerical value of determining usually, no matter their motion, or condition of road surface, or weather conditions.
Therefore, the air pressure of tire fluctuates according to temperature, and owing to some reasons of for example accidental release, it is flat that tire can become.In this case, we have to by inject and release change tire tolerance to keep suitable air pressure.
But the proper air pressure that we make great efforts to keep not is for the best of all situations.On the contrary, it is one that compromises.Therefore, if we want to have some special purposes of tire, we must use dissimilar tires.
Typically, when tire pressure was low, fuel mileage reduced, but the miles of relative movement of braking reduces suddenly.On the contrary, when tire pressure was high, fuel mileage improved, and cost is the stopping distance of aggravation.
Therefore, we want to inject suitable tolerance with good fuel mileage and the short stopping distance of compromising, and tire pressure remains unchanged.
Yet when very high speed, the air pressure that we must increase tire matches with load and speed with vehicle, with prevent tire by since the accumulation heat that its deflection produces damage, perhaps or even extreme blowing out.
Because the size in the speed of the hydroplaning of tire and vehicle and earthed surface zone is proportional, so we must increase the pressure of tire to remain on good tractive force on the wet road.But by snow-clad road, this may be braking suddenly only has effective ways with what stop: we will bleed a tire in large quantities, can apply their power on the ground so that be connected to the jag spike of wanting on the wheel rim.And the jag spike that works so can not bring discomfort on prevailing roadway.
The present invention can make tire have optimum pressure according to driving condition, weather conditions and condition of road surface, and this pressure can immediately be changed.
In case the installation tire need not manual intervention to keep needed pressure of its life-span.Therefore, this tire can have the unreactable gas as helium different with air, air its internal material that can burn.
Description of drawings
A pair of device of the present invention is installed on the interior wheel rim of tire.
This device can not only be let out according to the load on temperature regime, the tire, tire speed or accident Leak, by emitting a certain amount of gas from the super-pressure chamber or a certain amount of gas being filled back wherein Regulate the pressure of tire, and can when braking or condition of road surface change suddenly suddenly, pass through vacuum The operation of cylinder and super-pressure chamber comes immediately that tire pressure adjustment is extremely best.
Fig. 1 is the reduced graph that the wheel rim of two states air pressure can be arranged;
Fig. 2 has at length described the pressure regulator 2 among Fig. 1.
The specific embodiment
This device roughly it seems and is made up of vacuum chamber 1, pressure regulator 2 and superhigh pressure chamber 3 three parts, and the piston in the cylinder 14 is connected to regulating control 2 by linear gear 5, and chamber 3 is connected to regulating control 2 by pipe 7.
When tire rolling and bar 6 were pressed against landing ground, linear gear 10 was partly rotated external gear 8, and the swing pinion 9 of linear gear 11 parts.
When external gear 8 rotation, if inner gear 14 by electromagnetic switch 12 lockings, it clockwise rotates and is kept by unidirectional electromagnetic stop 13, linear gear 5 motions are with drawing piston 4.
By sensor for countering 15 position of piston 4 as can be known, and therefore when position that piston arrives requires, inner gear 14 is by switch 12 releases and no longer rotation.
When drawing piston 4, whole tire pressure rises.
When hill holder 13 discharged inner gear 14, piston 4 returned and whole tire pressure descends.
When external gear 9 rotation, if internals 17 by electromagnetic switch 18 lockings, it rotates counterclockwise and is kept by electromagnetic stop 19.
When bar 6 during away from ground, external gear 9 is replied by the power of plate spring 20.
By proximity transducer (access sensor) 22 position of piston rod 23 as can be known, and therefore when pump piston 24 arrives the bottom of pumping cylinders 25, internals 17 are unblanked by switch 18 releases and by hill holder 19, and it is by power answer of plate spring 21.
When no longer requiring pump action, switch 18 keeps release and part 17 to be pinned by hill holder 19, and by the joint operation of part 17 and external gear 9, the in-to-in alternating current generator produces electric current to charge to battery 26.
When no longer requiring the action of bar 6, unidirectional electromagnetic stop 16 pins external gear 8, and therefore bar 6 is maintained at minimum position.
When tire needed inflation suddenly, electromagnetic gas stopper 31 was by managing 32 gases of emitting required amount.
When gas sprayed by nozzle 34, it applied rotational force on the recess on the gear 14 33.
Therefore, if desired, vacuum chamber 1 is charged to a certain degree, and from that time, uses the normal inflation method by the motion of bar 6, and the gas of the additional quantity that produces is sent back in the chamber 3 by the operation of piston 24.
By reverse sensor (counting direction sensor) 35, measure the displacement of the bar 6 between top and bottom and weigh up load on the tire indirectly.
By centrifugal force sensor 30, measure the speed of tire, and pass through the unexpected variation of speed, can detect the sliding mode or the braking force of tire.
By pressure gauge 28 measure tire pressure and the pressure by pressure gauge 29 measuring chambers 3.
All data are sent to electronic controller 27, and it is according to based on their judgement or from all parts of instruction control of the center cell in the compartment.
Controller 27 is also reported the state of tire to center cell.
