Description
Technical field
The invention belongs to the vehicle control section part, be specifically related to the oil gas seal structure in a kind of go-anywhere vehicle usefulness Center Tyre Inflation.
Background technique
The road surface more complicated that offroad vehicle travels, usually need on muddy and soft surface, travel, according to the vehicle ground theory of mechanics, under the certain situation of ground friction coefficient and other conditions, tire-contact area is big more, and the ground traction that vehicle obtains is also just big more.Therefore,, change tire-contact area, just can play the effect that changes vehicle towed power by the regulating wheel air pressure.So the difference that performance reduces degree with tire pressure passed through of vehicle has in various degree enhancing.
How to realize that vehicle charges and discharge gas to tire in the process of moving, gas circuit is a great problem that central authorities charge and discharge the gas technology from the wheel that motionless vehicle body is communicated to rotation, what extensively adopt at present is in the assembly of wheel limit oil sealing and sealing gland to be installed, form the rotary seal gas circuit, oil sealing is used for preventing that the lubricant oil of taking turns in the assembly of limit from entering air flue.
Summary of the invention
The purpose of this invention is to provide a kind of effective oil, cyclone can realized and change the combined type oil gas envelope of sealing.
The present invention is achieved in that a kind of combined type oil gas envelope, and it comprises sealing gland, is provided with the sealing gland skeleton in the sealing gland, is provided with oil sealing in sealing gland, is provided with oil tight skeleton and oil seal spring in the oil sealing.

Embodiment
Describe the present invention below in conjunction with drawings and Examples:
A kind of combined type oil gas envelope, it comprises sealing gland 1, is provided with sealing gland skeleton 2 in the sealing gland 1, is provided with oil sealing 4 in sealing gland 1, is provided with oil tight skeleton 5 and oil seal spring 6 in the oil sealing 4.
Be provided with secondary oil sealing 23 in sealing gland 1, be provided with secondary oil tight skeleton 24 in the secondary oil sealing 23, oil sealing 25 is formed at the top of sealing gland 1.
Be provided with supporting ring 3 between described oil sealing 4 and the sealing gland 1.
Be provided with oil seal spring 6 on the oil sealing 25 on described.
Sealing gland forms a circular hole on its axial direction, support ring and oil sealing drive fit are successively packed into, the cylindrical of oil sealing with and its sealing gland of contacting between have rubber to realize sealing.
The diameter of bore of support ring 3 is slightly larger than the diameter of combined type oil sealing 4 installation shaft.
As shown in Figure 1, combined type oil gas envelope is made up of sealing gland 1 and sealing gland skeleton 2, oil sealing 4 and oil tight skeleton 5 thereof and oil seal spring 6, support ring 3.Sealing gland skeleton 2 glues with sealing gland 1 and is one, and oil tight skeleton 5 glues with oil sealing 4 and is one, and oil seal spring 6 is installed on the oil sealing 4, and the sealing gland skeleton forms a hole, and support ring 3 and oil sealing 4 drive fit are successively packed into wherein.The diameter of bore of support ring 3 is slightly larger than the diameter of combined type oil gas envelope installation shaft.
As shown in Figure 2, the combined type oil gas envelope is made up of sealing gland 1 and sealing gland skeleton 2, oil sealing 25, oil seal spring 6, secondary oil sealing 23 and skeleton 24 thereof.Sealing gland skeleton 2 glues with sealing gland 1 and oil sealing 25 and is one, and secondary oil tight skeleton 24 glues with secondary oil sealing 23 and is one, and the sealing gland skeleton forms a hole, and secondary oil sealing drive fit is packed into wherein.Skeleton 24 internal diameters of secondary oil sealing are slightly larger than the diameter of combined type oil gas envelope installation shaft, play the effect of supporting ring 3 among Fig. 1.
As shown in Figure 3, combined type oil gas envelope is made up of sealing gland 1 and support frame 32 thereof, oil sealing 25, oil seal spring 6.Support frame 32 glues with sealing gland 1 and oil sealing 25 and is one.Support frame 32 internal diameters are slightly larger than the diameter of combined type oil gas envelope installation shaft, play the effect of supporting ring 3 among Fig. 1.
The effect of Center Tyre Inflation be exactly vehicle advance or stopped process in adjust tire pressure, must realize the wheel of air flue from static to rotation.As shown in Figure 4, a pair of combined type oil gas envelope 9 is installed in the assembly of wheel limit.Two combined type oil gas seal 9 sealing glands the sealing gland drive fit are installed on the wheel hub 8, reinstall in the assembly of wheel limit, and with wheel hub 8 rotations, the lip of combined type oil gas envelope 9 cooperates with the axle of knuckle 7 realizes hermetic seal and oil seal.
