Abstract
A combined-type hub seal ring for a trailer axle comprises an inner oil seal, an outer oil seal and a lubricating oil surge impact-resistant retainer ring, wherein the inner oil seal comprises a support skeleton and an elastic seal body, the elastic seal body wraps and fixes the support skeleton, the extending part of the elastic seal body does not wraps and fixes the support skeleton, and is provided with a main lip mouth, and the opposite side of the main lip mouth is provided with a spring; the outer oil seal comprises a support skeleton and an elastic seal body, and the elastic seal body wraps and fixes on the outer surface of the support skeleton; the elastic seal body part on the bottom edge of the outer oil seal is matched and combined with the elastic seal body of the inner oil seal; and the lubricating oil surge impact-resistant retainer ring is arranged between the inner oil seal and the outer oil seal, and the upper part of the retainer ring is provided with a through hole. The utility model reduces the requirements on the surface finish quality and hardness of the hub and the shaft sleeve, and effectively avoids the impact of lubricating oil on the seal ring because the lubricating oil surge impact-resistant retainer ring with the through hole is added, thus realizing better sealing effect.
Description
Technical field
The utility model relates to a kind of seal arrangement, especially relates to a kind of trailer vehicle bridge combined type wheel hub seal ring.
Background technique
At trailer vehicle bridge wheel hub position, its motion mode is that wheel hub rotates, and it is static that axle sleeve keeps.As the seal ring that is installed between axle sleeve and the wheel hub, in order to realize better sealing effect, generally adopt the outside structural type of lip (referring to accompanying drawing 1), this structural type can guarantee reliable sealing when smooth operation.But under relatively poor road conditions, lubricant oil agitates in the chamber, seal ring is produced impact, and very easily causes oil leakage; Simultaneously, the seal ring of this structure is to the surface finishment and the hardness of the wheel hub fitting surface of cooperation have higher requirement with it.
The model utility content
The technical problems to be solved in the utility model provides a kind of trailer vehicle bridge combined type wheel hub seal ring; The sealing circle has adopted knockdown structure, all adopts the rubber material with the sealing position of wheel hub and axle sleeve, has reduced surface finishment and hardness requirement to wheel hub and axle sleeve; Increased the anti-lubricant oil that has through hole and agitated the impact back-up ring, effectively avoided the impact of lubricant oil, realized good sealing effect seal ring.
For solving the problems of the technologies described above, the utility model adopts following technological scheme, and it comprises that inner oil seal, outer oil seal and anti-lubricant oil agitate the impact back-up ring;
Described inner oil seal comprises support frame and elastic sealed body, the described elastic sealed body support frame that is coated and fixed, the extending portion of this elastic sealed body support frame that is not coated and fixed, and extending portion is provided with main lip, and the phase dorsal part of this main lip is provided with spring;
Described outer oil seal comprises support frame and elastic sealed body, and it is approximate L shaped that described support frame cross section is, and described elastic sealed body is coated and fixed at the outer surface of support frame;
The base elastic packing body portion of described outer oil seal combines with the elastic sealed body of described inner oil seal coupling;
Be provided with anti-lubricant oil between described inner oil seal and the outer oil seal and agitate the impact back-up ring, the top of this back-up ring is provided with through hole.
Further, the elastic sealed body of described inside and outside oil sealing adopts the rubber material.
Further, the support frame of described inside and outside oil sealing adopts steel or iron material matter.
The utility model has adopted knockdown structure, all adopts the rubber material with the sealing position of wheel hub and axle sleeve, has reduced surface finishment and hardness requirement to wheel hub and axle sleeve; Increased the anti-lubricant oil that has through hole and agitated the impact back-up ring, effectively avoided the impact of lubricant oil, realized good sealing effect seal ring.
