Problems solved by technology

Because the low air pressure controls the deflation process, it is prone to slow air leakage during the actual driving of the vehicle
The patent "CN101806369A Automobile tire central inflation and deflation system inflation and deflation valve assembly" uses a solenoid valve for inflation and deflation control. Due to the large size of the solenoid valve, the inflation and deflation valve can only be installed on the axle, and it needs to be installed on the tire valve. Tire valves are installed, and the system integration level is not high

Embodiment 1

[0045] like Figure 1-7 As shown, a compact central tire inflation and deflation system tire valve includes a valve body 1, a control valve core 3 and a one-way lock valve valve core 4. An air inlet 105 is provided on one side of the valve body 1, and the air inlet The intake joint 10 is installed in 105, the bottom of the valve body 1 is provided with a first boss 103, the lower part of the first boss 103 is provided with an exhaust port 104, the first boss 103 is provided with a stepped hole inside, and the inside of the stepped hole is A second sealing ring 14 is provided, the outside of the first boss 103 is provided with a bottom cover of the valve body 1, the middle of the bottom cover of the valve body 1 is provided with a first through hole 201 that communicates with the second sealing ring 14, and the bottom cover of the valve body 1 is opposite to the bottom cover of the valve body 1. The second sealing ring 14 is fixed; the middle of the valve body 1 is provided wit...

Embodiment 2

[0054] like Figure 11 As shown, the difference from Embodiment 1 is that in this embodiment, the dust-proof member 17 includes a thimble 1705, the front end of the thimble 1705 is a frustum-shaped structure, and the top ring 16 is provided with a stepped hole inside, and the thimble 1705 is provided with a stepped hole. 1705 is arranged inside the stepped hole, there is a gap between the lower part of the thimble 1705 and the wall of the large hole of the stepped hole, the front end of the thimble 1705 is in contact with the lower end of the small hole of the stepped hole, and the lower part of the top ring 16 is threadedly connected with an end cap 1707. There is a ventilation hole in the middle of the cap 1707, and a third spring 1706 is arranged inside the end cap 1707, and the upper end of the third spring 1706 is in contact with the lower part of the thimble 1705; when exhausting, the airflow pushes the thimble 1705 and flows out from the large hole of the stepped hole, a...

Embodiment 3

[0056] like Figure 12 As shown, the difference from Embodiment 1 is that in this embodiment, the bottom cover of the valve body 1 is a U-shaped gusset structure with a through hole on one side, and one end of the gusset plate is threaded with the valve body 1 through screws. The valve body 1 is provided with a positioning gusset 202 on one side, the front end of the bottom cover of the valve body 1 abuts against the inner wall of the positioning gusset 202, and the upper end of the bottom cover of the valve body 1 abuts against the upper wall of the positioning gusset 202. There are guide plates 203 on both sides of the 202. The positioning buckle plate 202 and the guide plate 203 are convenient for the quick positioning and installation of the bottom cover of the valve body 1. The guide plates 203 at both ends form a funnel-shaped structure with a large front opening and a small rear opening.

[0057] at rest, such as Figure 13 As shown, the control spool 3 of the tire va...

Abstract

The invention discloses a compact tire valve of a central tire inflation and deflation system. The compact tire valve comprises a valve body, a control valve element and a one-way locking valve element, a control valve cavity for containing the control valve element is formed in the middle of the valve body, a one-way locking valve cavity for containing the one-way locking valve element is formed in the middle of a valve body top cover, a guide sleeve is arranged in the one-way locking valve cavity, the one-way locking valve comprises a guide rod arranged in a guide hole in a clearance mode and a valve element seat arranged in the middle of the guide rod, a first sealing ring is arranged outside the valve element seat, a second spring is arranged on the upper portion of the valve element seat, a first spring is mounted outside a limiting guide step, a lip-shaped sealing ring is arranged in a hole wall groove, and a sealing guide piece is arranged in a first sealing groove. Multi-stage sealing is formed on the tire valve through the lip-shaped sealing ring, the first sealing ring, the sealing guide piece and a second sealing ring, the air leakage phenomenon in the using process of the tire valve is avoided, the tire valve has the advantages of being high in integration degree and compact in structure, and the size and weight of the tire valve are reduced.

Description

technical field [0001] The invention belongs to the technical field of tire valves, in particular to a tire valve of a compact central tire inflation and deflation system. Background technique [0002] The central inflation and deflation system can precisely change the tire pressure of the vehicle through the air pressure adjustment device during driving to adapt to various terrains and application needs, improve the mobility and fuel economy of the vehicle, in trucks, tractors, construction vehicles, agricultural equipment , off-road vehicles and military vehicles and other vehicles have a large number of applications. [0003] When the vehicle is driving at high speed on a smooth road, the economy and safety can be improved by increasing the tire pressure to reduce the driving resistance; while on relatively soft terrain such as swamps, sand, and snow, by reducing the tire pressure pressure, increasing the contact area of ​​the tire with the ground to improve adhesion and...
