Abstract
An automatic inflating and deflating device for tyres of a special vehicle. The device comprises a gas pipeline, an input end gas pipe joint, an oil gas sealing device, an O type sealing ring, an output end gas pipe joint that are arranged on each vehicle bridge of the whole vehicle, and a whole vehicle gas pipeline connected with each vehicle wheel. The input end gas pipe joint is mounted on a steering knuckle or a head of each vehicle wheel of the whole vehicle; one end of the input end gas pipe joint is connected to a vehicle tire pressure regulation system through the whole vehicle gas pipeline, and the other end of the input end gas pipe joint is connected with one end of the output end gas pipe joint arranged on a wheel hub through the gas pipeline; and the other end of the output end gas pipe joint is connected with the tires. The oil gas sealing device is arranged between the wheel hub and the steering knuckle (or head) through a clamping ring; the wheel hub and the steering knuckle or head is provided with a processing airway, which communicates with a corresponding through hole on the oil gas sealing device. The device provided by the invention can quickly adjust the tire pressure, ensure the normal running of vehicle on soft ground and aerate the tire for emergency; besides the device is easily operated to improve traveling performance of the vehicle.
Description
Technical field
The present invention relates to a kind of fast automatic aerating and exhaust device of tire; Especially the automatic aerating and exhaust device of extraordinary tire for vehicles; This device is connected with the former entire vehicle tyre pressure regulation system of automobile; The adhesive ability of vehicle under special road conditions be can improve, thereby traction property, braking ability and the crossing ability of automobile improved.
Background technology
Tire is the vitals in the running car system; Mounting of tyre is also inflation on wheel rim; Directly contact when going with the road surface; Its effect is: 1 and automotive suspension suffered impact when relaxing running car jointly, and the vibration that produces therefrom of decay, to guarantee automobile good travelling comfort and riding comfort are arranged; 2, guarantee that there is good tack on wheel and road surface, to improve traction property, braking ability and the crossing ability of automobile; 3, bear the gravity of automobile, and transmit the power and the moment of other directions.And therefore special purpose vehicle more often travels on soft, muddy road surface is prone to sink into soft surface, influences the crossing ability of automobile; To this problem, at present mainly is to adopt the tire of extraordinary patterned tread and the mode that reduces tire pressure to solve, but the method that reduces tire pressure at present is one by one tire to be exitted with manual mode; Automobile manually puts on the air each tire after through soft surface again; Inconvenient operation, and the used time is long, influences running car.
Summary of the invention
The objective of the invention is:, provide a kind of extraordinary tire for vehicles automatic aerating and exhaust device, the air pressure of fast automatic adjusting tire to the problems referred to above; Guarantee that automobile is when soft terrain goes; Can reduce tire pressure as required automatically, increase tire ground contact area, reduce its unit area load, thereby improve the crossing ability of automobile, being that tire is emergent when leaking gas when puncture of tire in addition inflates; Guarantee that the required air pressure of tire makes automobile continue in short-term to go, do not need changing of tire at once.For achieving the above object, the present invention adopts following scheme:
The automatic aerating and exhaust device of said extraordinary tire for vehicles; Comprise the gas pipe line that is installed on each vehicle bridge of car load, input end gas-tpe fitting, oil gas sealing arrangement, O RunddichtringO, mouth gas-tpe fitting and with each wheel bonded assembly car load gas pipe line of car load; Wherein said input end gas-tpe fitting is installed on each wheel steering joint of car load or the spindle nose; One end is connected with the vehicle tyre pressure regulation system through the car load gas pipe line; The other end is connected with mouth gas-tpe fitting one end on being installed in wheel hub through gas pipe line, and the other end of mouth gas-tpe fitting is connected with tire; The oil gas sealing arrangement is packed between wheel hub and steering swivel or the spindle nose through snap ring, is processed with air flue on wheel hub and steering swivel or the spindle nose, and said air flue is communicated with the corresponding through hole of oil gas sealing arrangement.
Adopt transition fit between said oil gas sealing arrangement and the wheel hub, and form sealing through two O RunddichtringOs and wheel hub.
In the said oil gas sealing arrangement through hole rotary shaft lip seal is housed, and forms sealing between steering swivel or the spindle nose.
