Description
Technical field
The present invention relates to a kind of inflation regulator of automobile tyre, be specially a kind of device that is used for adjusting and controlling pressure of tire.
Background technology
The wheel of self-propelled vehicle and tire are the vitals of self-propelled vehicle, and present automobile nearly all adopts air-inflation tyre.The in use maximum problem of air-inflation tyre is the tire pressure of tire, and tire pressure causes pressure bearing improperly when not enough, quickens the tire worn-down simultaneously, also can reduce handling to automobile.Increase in temperature in the tire pressure deficiency, tire can cause tire failure.And the tire pressure deficiency of tire, also cause the generation of automobile contingency easily, run at high speed during low tyre, can cause controlling bad, blow out, thereby can produce the accident of overturning, when rear tire air pressure is not enough, can cause front wheel alignment bad, the bearing circle deflection, control is painstaking.When tire pressure was too high, the tire earth-grasping force reduced, and braking quality reduces, and tire pressure is crossed the low damage that can cause undue wear or inside tires to fail to discover.Simultaneously, tire pressure is low excessively, has strengthened the rolling resistance of tire, has increased the consumption of fuel, and the fragile carcass that runs flat stays hidden danger for blowing out; Disposable qi of chong channel ascending adversely is too high, makes the performance of tyre buffering road shocks descend, and fragile suspension and body parts reduce vehicle and take advantage of traveling comfort for sleeping in; In addition, when vehicle was run at high speed on the expressway, damage tyre was blown out because of the rapid rising of tire pressure easily.The slowly disappointing phenomenon of existing tire ubiquity, this phenomenon causes automobile not travel under correct tire pressure for a long time.
Summary of the invention
For overcoming the deficiencies in the prior art, the object of the present invention is to provide a kind of device that is used for adjusting and controlling pressure of tire, this device can guarantee that tire is in work under the correct tire pressure, prevents to blow out, and adjustable tire pressure, be implemented in the middle adjusting and controlling pressure of tire of advancing to adapt to different road conditions.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of device that is used for adjusting and controlling pressure of tire, its structural feature is: on the tire wheel shaft rotor is installed, this rotor is provided with the aeration zone device, this aeration zone device comprises aeration zone, in the middle of this aeration zone is air flue, these air flue two ends are respectively admission port and air extractor duct, said air extractor duct is communicated with tire air chamber by soft air-guide pipe by check valve, said admission port is communicated with the tire of getting a breathing space by soft air-guide pipe by change-over valve, the said tire of getting a breathing space is communicated with tire air chamber by soft air-guide pipe by control cock, erection column plug cylinder body mechanism on the frame, the plunger of this plunger cylinder mechanism connects roller mechanism.Vehicle is in advancing, and by roller extruding aeration zone, the pressure gas in the feasible tire of getting a breathing space enters air chamber via aeration zone by tire tube valve, finishes the inflation to air chamber.Threshold values by adjusting control valve is implemented in the middle adjusting and controlling pressure of tire of advancing to adapt to different road conditions.
Said check valve is boiler check valve or common charge valve.
Said plunger cylinder is communicated with pressure source by a normally closed solenoid valve, and this pressure source is vehicle-borne pneumatic supply or hydraulic power source.Utilize vehicle-borne pneumatic supply or hydraulic power source that pressure is provided, make roller push or not push aeration zone.
Said rotor one side is provided with guide ring, and draws three electrodes that are used for transmission of control signals or on-off signal from the opposite side of rotor.
The said tire of getting a breathing space is a ring-shaped air chamber, is set on the supporter and is installed on the wheel rim inboard, is filled with the pressure gas that air pressure is lower than tire air chamber air pressure in the air chamber.
Said change-over valve is connected a filter with the valve port of outside air conducting.The effect of filter is the air flue that prevents that moisture in the outside air and dirt from entering aeration zone, stops up air flue.
The invention has the beneficial effects as follows that in car, inflation pressure is desirable to adapt to different road surfaces in the change tire, this point is even more important in cross country car.This just need provide a kind of structure and technology simple, automotive system is just changed a little can be assembled the gas filled device that uses, and realizes being inflation of tire under the particular case in vehicle is advanced, and can realize controlling from automobile cab simultaneously.The present invention utilize the local extruding of roller be arranged on the wheel shaft with the coaxial rotor rotated of tire on aeration zone the air pneumatic tyre of postponing is charged into tire air chamber, in being implemented in and advancing by control cock, get a breathing space tire and connecting line to the adjusting and the control of pressure of tire.The present invention can set the tire pressure value of tire by adjusting control valve, realizes that tire pressure is adjustable.Control process is as follows: when the gas pressure value in the air chamber was higher than the threshold values of control cock, control cock was opened the gas that makes in the proloculum and is entered the tire of getting a breathing space, and the gas atmosphere value in proloculum drops to threshold values, and control cock is closed and stopped exhaust; When air chamber pressure is lower than the threshold values of control cock, the conducting of control cock contact switch, the electromagnetic valve circuit energising, electromagnetic valve is opened, and the pressure source fluid enters plunger cylinder, and the plunger that promotes in the cylinder body moves, plunger drives the local extruding of roller aeration zone, vehicle makes the pressure gas of being derived by the tire of getting a breathing space enter tire air chamber through air flue, the check valve of aeration zone through soft air-guide pipe in motion like this, finishes the inflation to tire.Tire whenever rotates a circle and just finishes a gas replenishment process, and when tire air chamber air pressure reached the threshold values of setting, the control cock contact switch disconnected, and electromagnetic valve circuit disconnects, and solenoid closure, roller stop to push aeration zone, and gas replenishment process finishes; When the atmospheric pressure value in the tire of getting a breathing space is lower than setting value, the change-over valve transposition, make the admission port of aeration zone be communicated with outside air, change-over valve contact switch conducting simultaneously, electromagnetic valve is opened, the local extruding of roller aeration zone, outside air charges into tire air chamber via aeration zone, make air chamber air pressure raise, when air chamber air pressure surpassed the setting value of control cock, control cock was opened, and gas enters the tire of getting a breathing space, air pressure in the tire of getting a breathing space stops gas replenishment process when reaching setting value, the feasible tire of getting a breathing space keeps certain air pressure.The present invention realizes the adjusting to pressure of tire, makes automobile travel under correct tire pressure, keeps good handling, prevents to blow out the raising fuel efficiency; When meeting uneven road surface, can make tire pressure reduce, reach and slow down the impact that uneven road surface brings by regulating, make take advantage of crouch comfortable; If on soft road surface such as snowfield, muddy road, sandy beach, travel, can reduce tire pressure by regulation and control, to increase the ground ability of grabbing of tire, improve traction state, strengthen the vehicle carrying capacity.Realize vehicle in motion by the present invention, kept pressure of tire to be in the correct tire pressure value scope, effectively stopped the protection carcass that runs flat, prevented because of the blowing out of the too high initiation of tire pressure, and can realize that pressure of tire is adjustable, adapted to the road conditions of different brackets.
