Description

Automobile tyre rim valve

Technical field

The present invention relates to a kind of vehicle charging and discharging valve, relate in particular to a kind of automobile tyre rim valve of cross-country vehicle tire central air-charging and air-discharging system.

Background technique

The locking valve technology very early by national expenditures such as the U.S., Russia in charging and discharging on the gas automobile tire.Its effect is to block air-flow between tire and rotary seal air chamber by closing locking valve when automobile running, thereby gives the tire pressurize and reduce the wearing and tearing of rotating seal ring; When parking of automobile, tire is communicated with the rotary seal air chamber, thereby gives tyre inflation, venting and pressure measurement by locking valve.

Because of the pressure maintaining performance of locking valve, determined locking valve when turn-offing, must have good sealability.If locking valve gas leakage, tire pressure will descend immediately, and this is breakneck when vehicle driving.Offroad vehicle travels in the rugged environment of being everlasting, and locking valve is contained on the wheel hub, outside it is exposed to fully.It is well corrosion-resistant that this just needs locking valve to have, the high-low temperature resistant characteristic.Though external locking valve has solved above these problems, the cost of the external Component of import is higher, and the cycle is long.

Automobile tyre rim valve is with locking valve and charges and discharge the novel valve body that feed channel combines together, still do not have this structure at present at home.

Summary of the invention

Purpose of the present invention just is to overcome the above-mentioned shortcoming and defect that prior art exists, and a kind of automobile tyre rim valve of cross-country vehicle tire central air-charging and air-discharging system is provided.

The object of the present invention is achieved like this:

Develop a kind of sealing configuration, guarantee the sealing of automobile tyre rim valve; With locking valve with charge and discharge feed channel and combine together, reduce installation procedure.

As Fig. 1, the present invention includes Taper Pipe valve body (1), sliding sleeve (2), the 3rd spring (3), compressing tablet (4), the one O shape circle (5), the 2nd O shape circle (6), dust cap (7), valve inside (8), slide valve (9), round nut (10), the 3rd O shape circle (11), locking nut (12), first gas-tpe fitting (13), clip (14), tracheae (15), second gas-tpe fitting (16), attaching nut (17), sealing gasket (18), valve inside holder (19), the 4th O shape circle (20), first spring (21), second spring (22), spacing thimble (23), dust-proof cover (24), steel traveler (25).

Working principle of the present invention is:

The present invention only provides a valve assembly, is matching used with special detection control system.

As Fig. 1, the A mouth (a) of automobile tyre rim valve communicates with B mouth (b), and automobile tyre rim valve is in running order; When pressing lower sheeting (4), compressing tablet (4) breaks away from the draw-in groove of Taper Pipe valve body (1), under the effect of spring (21), Taper Pipe valve body (1) moves down, its two lead to the hole site in upper end are under the 4th O shape circle (20), and A mouth this moment (a) turn-offs with B mouth (b), and wheel limit valve is in off working state; When pressing slide valve (9), spacing thimble (23) moves down simultaneously, until contacting with Taper Pipe valve body (1), reaction force forces on the spacing thimble (23) and moves, compressing tablet this moment (4) breaks away from the restriction of spacing thimble (23) and generation displacement left under the effect of the 3rd spring (3), compressing tablet (4) blocks the draw-in groove of Taper Pipe valve body (1), and the A mouth (a) of wheel limit valve communicates once more with B mouth (b), and automobile tyre rim valve is in running order again.

The present invention has following advantage and good effect down:

1, in light weight, can reduce centrifugal force, cost is low;

2, adopt sliding valve structure, easy to operate, good seal performance;

3, on valve body also design have one can for outside charge and discharge the valve cock of gas, can adopt external source of the gas to give tyre inflation when guaranteeing the central air-charging and air-discharging system fault.
