Abstract
The utility model discloses a wheel hub used in a central tire inflation and deflation structure, comprising a wheel hub body. The wheel hub body is sheathed outside an oil seal seat, a shaft head airway is arranged in a shaft head wall, a wheel hub airway is arranged in the side wall of the wheel hub body, an annular air chamber surrounding the oil seal seat for at least one circle in a closed way is formed by a gap between the inner wall of the wheel hub body and the outer wall of the oil seal seat, the wheel hub airway is communicated with the annular air chamber, and the annular air chamber is communicated with the shaft head airway. The wheel hub has the beneficial effects that the wheel hub is more suitable for being used on vehicles with central automobile tire inflation and deflation systems, the automobile tire inflation and deflation in the process of driving can be conveniently adjusted according to different driving road surfaces, and the wheel hub is comparatively perfect and reliable, simple in structure, convenient in maintenance and long in service life.
Description
Technical field
The utility model relates to the central inflation/deflation structure wheel hub of a kind of tire, belongs to the chassis annex.
Background technology
At present, the motor tire central air-charging and air-discharging system can improve the ground maneuverability of wheeled car and vehicle-mounted equipment thereof significantly, comprise crossing ability, obstacle detouring, the run flat ability, ride comfort, fuel economy, Tyte Wear and life-span etc. are all improved to some extent, especially for military vehicle remarkable strategic importance is arranged: improve military vehicle at seashore, the desert, accumulated snow, crossing ability on the soft terrains such as mire, improve the disappointing driveability of army's vehicle tyre, thereby improve the viability of military vehicle, improve the military vehicle riding comfort, reduce the damage of equipment and important weapon, regulate the military vehicle height within the specific limits, adapt to the motor-driven requirement of transportation.But in the vehicle ' process motor tire that rotates being charged and discharged gas is a relatively thing of difficulty, does not also comparatively improve at present and reliable solution.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of tire central inflation/deflation structure wheel hub, can charge and discharge gas for the tire that is provided with central inflation/deflation structure easily.
The utility model is realized by following measure:
A kind of tire of the utility model central authorities inflation/deflation structure wheel hub, comprise hub body, described hub body is enclosed within outside the oil seal seat, be provided with the spindle nose air flue in the spindle nose wall, be provided with the wheel hub air flue in the described hub body sidewall, form at interval closed ring between hub body inwall and the oil seal seat outer wall around the ring-shaped air chamber at least one week of oil seal seat, the wheel hub air flue is connected with ring-shaped air chamber, and ring-shaped air chamber is connected with the spindle nose air flue.
Give inflation of tire for convenience, above-mentioned wheel hub air flue is circumscribed with the wheel valve.
Above-mentioned hub body is provided with the standby or detection port that communicates with the wheel hub air flue, can be conveniently as standby or be used to detect the wheel hub air flue.
The beneficial effects of the utility model are:
Be adapted at more having on the vehicle of motor tire central air-charging and air-discharging system and use, the motor tire that can regulate easily in the driving process according to different tracks charges and discharge gas, and is fairly perfect and reliable, and simple in structure, easy to maintenance, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 hub body, 2 take turns valve, 3 standby or detection port, 4 ring-shaped air chambers, 5 speed reduction gearings, 6 wheels are installed nut, 7 wheel hub air flues.
The specific embodiment
As shown in Figure 1, a kind of tire of the utility model central authorities inflation/deflation structure wheel hub, comprise hub body 1, hub body 1 is enclosed within outside the oil seal seat, be provided with wheel hub air flue 7 in hub body 1 sidewall, form at interval closed ring between hub body 1 inwall and the oil seal seat outer wall around the ring-shaped air chamber 4 at least one week of oil seal seat, wheel hub air flue 7 is connected with ring-shaped air chamber 4, and ring-shaped air chamber 4 is connected with the spindle nose air flue.Above-mentioned wheel hub air flue is circumscribed with wheel valve 2.Hub body 1 is provided with the standby or detection port 3 that communicates with wheel hub air flue 7.Semiaxis drives and connects speed reduction gearing 5.Wheel is installed nut 6 by wheel and is installed on the wheel hub.
Its principle of work is: the gas of external air source enters the spindle nose air flue in the spindle nose, enter into ring-shaped air chamber 4 through air extractor vent then, because ring-shaped air chamber 4 is closed annular, therefore full annular air chamber 4 has been full of gas, gas in the ring-shaped air chamber 4 has flow to wheel valve 2 from wheel hub air flue 7 then, thereby is automobile tyre inflation.Because automobile in the process of moving, wheel hub is in rotation, and spindle nose partly is static, owing to designed ring-shaped air chamber 4, therefore the admission port of wheel hub air flue 7 keeps communicating with ring-shaped air chamber 4 all the time, realized that gas is delivered to the wheel tyre of rotation from static pipeline, the motor tire of regulating in the driving process by the supply of control external air source charges and discharge gas.Oil sealing adopts good seal and abrasion resistant material.By the charge and discharge gas of instrument operation realization, satisfy of the requirement of different road conditions to air pressure, tyre contact patch to tire.Be mainly used in the independent suspension structure cross-country car.
The foregoing description is described to be in order to specify this patent; though describe by specific term in the literary composition; but can not limit the protection domain of this patent with this; being familiar with the personage of this technical field can be after the spirit of understanding this patent and principle change or revises it and reach equivalent purpose; and this equivalence change and modification all should be covered by the claim scope and define in the category.
