Abstract
The utility model relates to a seal device which is especially applicable to an automatic inflation/deflation system of a cross-country car chassis. The utility model discloses a seal air-tight device which comprises a ring body, two lip-shaped sealed rings and an O-shaped sealed ring, wherein the two lip-shaped sealed rings are respectively installed at two axial sides of the inner wall of the ring body. The utility model has compact structure, small volume, light weight and good sealing property, and can meet the requirements of the chassis of automatic inflation while driving. In brief, the utility model has simple structure, convenient manufacturing, easy installation and operation, low cost and good using effect.
Description
Technical field
The utility model relates to a kind of seal arrangement, is particularly useful in the automatic inflating-pressure releasing system of cross country chassis.
Background technique
China Sanjiang Space Industry Group Corp is in 10 months 8 days year in 2003 proposing the patent application that name is called the double-lip seal gas check, and its notice of authorization day is on October 27th, 2004, and the patent No. is 200320100047.2.
There is following defective in this double-lip seal gas check application in practice:
1. this device is made of two pairs of lip-type packings, and each only seals a kind of medium to seal ring, a pair of sealing oil, a pair of blanket gas, boundary dimension is bigger, and travelling of vehicle makes that generation relativity power is big between sealing device and wheel hub and the axle tube, makes sealing state undesirable.
2. this device of the prior art, the chassis can only charge and discharge gas under vehicle stop state, and sealing effect is general, is prone to the seepage phenomenon.
The model utility content
Technical problem to be solved in the utility model provides a kind of sealing gas check, it has a pair of lip-type packing of employing, seal ring one side sealing oil, one side sealing gas, make compact overall structure, boundary dimension little, in the running process of chassis, the rotary inertia of device is little, followability good, thereby can improve the characteristics of sealability.
For solving the problems of the technologies described above, a kind of sealing gas check provided by the invention comprises ring body, lip-type packing and O RunddichtringO, it is characterized in that, the quantity of described lip-type packing is two, is installed in the axial both sides of described inner wall of ring body respectively.
Improvement project to above-mentioned fondational structure is that the side sealing circle surface of described lip-type packing sealing oil is a zigzag structure.
Optimized project to said structure is that described ring body is the aluminum alloy ring body.
The invention has the advantages that:
1. adopt a pair of lip-type packing, make that the integrally-built boundary dimension of a kind of sealing gas check provided by the utility model is little, thereby reach the purpose that in the vehicle driving process, guarantees sealing effect.Solved in the prior art because plant bulk is big, caused the unfavorable problem of sealing state.
2. by being zigzag structure, can form the oil storage line when making sealing oil, and can reduce the friction factor at this place, thereby further improve sealing effect on the side sealing circle surface of lip-type packing sealing oil.
3. adopt the material of aluminum alloy as ring body, make the device light weight, add that overall dimensions of the present utility model is little, make in the running process of chassis, the rotary inertia of sealing gas check provided by the utility model is littler, follow that more property is good, and owing to the side sealing circle surface with the lip-type packing sealing oil is a zigzag structure, make sealing effect be improved, thereby make the utility model can satisfy chassis requirement of inflation automatically while travelling.
The utility model compact structure, little, in light weight, the good seal performance of volume can satisfy chassis requirement of inflation automatically while travelling.In a word, the utility model simple in structure, easy to make, be easy to installation and operation, cost is low, using effect good.
Description of drawings
Below in conjunction with the drawings and specific embodiments technological scheme of the present invention is further described in detail.
Fig. 1 is a cross-sectional view of the present utility model.
Wherein, 1-O shape seal ring, 2-ring body, the saw tooth structure that is provided with on the side of 3-lip-type packing oil sealing, the opening of offering on the 4-ring body that is connected with air input joint.
Embodiment
At first, with reference to the cross-sectional view of the present utility model shown in the accompanying drawing 1, make the utility model: the employing aluminum alloy processes the ring body 2 in the utility model, on ring body 2, offer the opening that is connected with air input joint, a groove that is used to install O RunddichtringO 1 is offered at the two ends of the outer wall of ring body 2 on one side, and O RunddichtringO 1 is installed in the groove of offering on ring body 2 outer walls.In the axial both sides of ring body 2 inwalls a lip-type packing is installed respectively, a side sealing circle surface of lip-type packing sealing oil is set to zigzag structure 3, and during installation, the saw tooth structure 3 in the assurance lip-type packing is towards the both sides of ring body 2.This moment, promptly finish a kind of making and assembling that seals gas check that the utility model provides.
Then, the utility model of making as stated above and assembling is installed in the automatic inflating-pressure releasing system of vehicle chassis: utilize ring body 2 to be enclosed within on the axle tube, in the outer wall both sides of ring body 2 jump ring is installed respectively, on the nave boss inwall, offer the jump ring groove, the utility model is installed between nave boss and the axle tube, jump ring on ring body 2 outer walls is snapped in the groove of nave boss, in order to restriction the utility model front and back position, the O RunddichtringO 1 on ring body 2 outer walls will be tightly connected between ring body and the nave boss.
It should be noted last that, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technological scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
Claims (3)
1. a sealing gas check comprises ring body, lip-type packing and O RunddichtringO, it is characterized in that, the quantity of described lip-type packing is two, is installed in the axial both sides of described inner wall of ring body respectively.
2. a kind of sealing gas check as claimed in claim 1 is characterized in that, the side sealing circle surface of described lip-type packing sealing oil is a zigzag structure.
