Abstract
The invention discloses an internal compression seal ring of a two-gear planet gearbox of a pure electric vehicle through axle. The internal compression seal ring comprises a seal ring body, the seal ring body is made of hydrogenated nitrile rubber buna and in a round shape, an air cavity is formed in the seal ring body, and a fixed groove is formed in the seal ring body and communicated with the air cavity. A set of annular seal ribs are arranged on the seal ring body and are located on the two sides of the fixed groove respectively. The internal compression seal ring is simple in structure, the highest temperature for using the hydrogenated nitrile rubber buna is 150 DEG C, the lowest temperature for using the hydrogenated nitrile rubber buna is minus 10 DEG C, and the internal compression seal ring is resistant to gear lubricant, not prone to being damaged and long in service life.
Description
Technical field
The present invention relates to seal ring field, refer more particularly to a kind of pure electric vehicle and connect vehicle bridge second gear planetary transmission internal pressure type seal ring.
Background technique
Existing seal ring kind is a lot, but all can not be high temperature resistant, not ability gear lubricant, and cracky, and also rigidity is large, and structure shape is unreasonable, easily drawing crack.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art and provide a kind of simple in structure, practical pure electric vehicle to connect vehicle bridge second gear planetary transmission internal pressure type seal ring.
The present invention realizes in the following way:
A kind of pure electric vehicle connects vehicle bridge second gear planetary transmission internal pressure type seal ring, comprise seal ring body 1, it is characterized in that: described seal ring body 1 adopts hydrogenation nitrile rubber material to make, described seal ring body 1 is circular, which is provided with air cavity 2, described seal ring body 1 is provided with fixed groove 3; Described fixed groove 3 is connected with air cavity 2; Described seal ring body 1 is provided with one group of ring packing muscle 4; Described ring packing muscle 4 lays respectively at the both sides of fixed groove 3.
Beneficial effect of the present invention is: simple in structure, hydrogenation nitrile rubber material rubber uses 150 degrees Celsius of maximum temperatures, minimum temperature-10 degree Celsius, and resistance to gear lubricant, not fragile, long service life.
Accompanying drawing explanation
Fig. 1 structural section schematic diagram of the present invention.
Embodiment
Now by reference to the accompanying drawings, the specific embodiment of the invention is described in detail in detail:
As shown in Figure 1, a kind of pure electric vehicle connects vehicle bridge second gear planetary transmission internal pressure type seal ring, comprises seal ring body 1, described seal ring body 1 adopts hydrogenation nitrile rubber material to make, seal ring body 1 is circular, which is provided with air cavity 2, and seal ring body 1 is provided with fixed groove 3; Fixed groove 3 is connected with air cavity 2; Seal ring body 1 is provided with one group of ring packing muscle 4; Ring packing muscle 4 lays respectively at the both sides of fixed groove 3.
The present invention adopts hydrogenation nitrile rubber material rubber to make, it uses 150 degrees Celsius of maximum temperatures, minimum temperature-10 degree Celsius, and resistance to gear lubricant, seal ring surface should be bright and clean, pore-free, pit, crackle, in seal ring without dust granules, bubble, be mingled with, rigidity is little, and material is soft, and tear strength is checked and accepted by this trade mark material rubber parts of country.
When use, steel plate 5 is connected in air cavity 2 by fixed groove 3, makes air cavity 2 form the cavity of a sealing; Then by screw, steel plate 5 is fixed on the end cap wall of the bridge second gear planetary transmission that is open to traffic.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
