Description
Technical Field
The utility model belongs to the technical field of, especially, relate to a seal structure of automatic transmission selection fender casing.
Background
In the traditional gear selecting shell structure, the matching between a sealing groove and a sealing ring is not tight, and the Y-shaped sealing ring has small compression amount and is unidirectional in sealing due to the small diameter of the sealing groove, so that the reverse air pressure sealing effect is poor, and the risk of air leakage of a gear selecting box exists; the Y-shaped sealing ring with the existing structure is a pure import, has certain difficulty in quality control, cannot react quickly once a problem occurs, and influences overall production and delivery.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome prior art not enough, provide a seal structure of automatic transmission selection fender casing.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a sealing structure of a gear selecting shell of an automatic gearbox comprises a shell with a mounting hole and a sealing ring arranged in the mounting hole, wherein a sealing groove and a guide ring mounting groove are arranged in the mounting hole, the guide ring mounting groove is arranged on the inner side of the sealing groove, a V-shaped groove is formed in one side of the sealing ring, a bulge is formed in the other side of the sealing ring, and a clamping groove matched with the bulge is formed in the sealing groove; the guide ring mounting groove is formed in the inner side of the sealing groove, so that the sealing ring is easier to assemble, and the production efficiency is improved; the sealing washer side is equipped with the arch, and the seal groove be equipped with protruding complex draw-in groove, sealing performance is more excellent.
Preferably, an arc-shaped groove is formed in the inner wall of the sealing ring; further improve the sealed effect of sealing washer.
Preferably, the protrusion is provided with an inclined surface; the protrusion that sets up the inclined plane and make can play the guide effect, the sealing washer installation of being convenient for.
In conclusion, the guide ring mounting groove is arranged on the inner side of the sealing groove, so that the sealing ring is easier to assemble, and the production efficiency is improved; the sealing washer side is equipped with the arch, and the seal groove be equipped with protruding complex draw-in groove, sealing performance is more excellent.
