The invention provides a durable sealing ring for vehicles. The durable sealing ring comprises a sealing ring body. An external sealing lip and an internal sealing ring are arranged at the top of the sealing ring body, a V-shaped groove is formed between the external sealing ring and the internal sealing ring, and the bottom of the V-shaped groove is in smooth transition; an annular elastomer is arranged in the sealing ring body, the section of the annular elastomer is Y-shaped, the annular elastomer comprises a first elastic portion, a second elastic portion and a third elastic portion which are mutually connected, the first elastic portion is arranged in the external sealing lip, the second elastic portion is arranged in the internal sealing lip, the joint of the first elastic portion and the second elastic portion is in circular arc transition, the third elastic portion is arranged in the sealing ring body, and the length of both the first elastic portion and the second elastic portion is smaller than that of the third elastic portion. By the arrangement, annular elastic parts are arranged in the sealing ring body, elasticity of the sealing ring is increased, and service life of the sealing ring is prolonged.
Description
technical field [0001] The invention relates to the technical field of sealing rings, in particular to a durable sealing ring for automobiles. Background technique [0002] The sealing ring is very important for the reciprocating dynamic sealing device, but the general O-ring can no longer meet the market demand, the effect is not obvious and the service life is not long, and it is easy to be damaged, which brings inconvenience to the production and delays the production time, reducing machine performance and productivity. The Y-shaped sealing ring is attached to the coupling surface of the sealing pair by its opened lip. When there is no internal pressure, only a small contact pressure is generated due to the deformation of the lip tip. In the case of sealing, every point in contact with the sealing medium has a normal pressure equal to the medium pressure, so the bottom of the lip ring will be compressed axially, the lip will be compressed circumferentially, and the cont...
