Problems solved by technology
[0003] The purpose of sealing is achieved only by setting a single-layer sealing ring between the outer ring of the existing hub unit and the flange. However, firstly, the sealing effect of the single-layer sealing is poor. Heat, the heat is transferred to the outer ring of the hub unit, resulting in an increase in the ambient temperature of the sealing ring, which accelerates the aging of the sealing ring and shortens the service life of the sealing ring

The invention discloses a sealing ring assembly. The sealing ring assembly comprises a sealing ring used for sealing between a hub unit outer ring and a flange, the bottom of the sealing ring abuts against the inner surface wall of the hub unit outer ring, a groove is formed in the sealing ring, the bottom of the flange is bonded in the groove through cold vulcanization glue, the outer surface wall of the sealing ring is fixedly connected to a first sealing support and a second sealing support which abut against the inner surface wall of the hub unit outer ring, a plurality of fixing blocks are fixedly installed in the hub unit outer ring, moving grooves are formed in the fixing blocks, and one ends of the moving grooves are elastically connected to first springs. According to the sealing ring assembly, the sealing ring abuts against the inner surface wall of the hub unit outer ring to form a first layer of sealing, the first sealing support abuts against the inner surface wall of the hub unit outer ring to form a second layer of sealing, the second sealing support abuts against the inner surface wall of the hub unit outer ring to form a third layer of sealing, and the sealing effect of the device is enhanced through the three layers of sealing.
Description
technical field [0001] The invention relates to the technical field of sealing devices, in particular to a sealing ring assembly. Background technique [0002] The car hub is an important part of the car. The car hub plays a vital role in the safety system of the car. The car hub unit includes a mandrel, an outer ring and an inner ring, and the outer ring of the hub unit needs to be assembled with the flange. Together, and considering the safety of use, a sealing structure needs to be provided between the outer ring of the hub unit and the flange. [0003] The purpose of sealing is achieved only by setting a single-layer sealing ring between the outer ring of the existing hub unit and the flange. However, firstly, the sealing effect of the single-layer sealing is poor. Heat, the heat is transferred to the outer ring of the hub unit, resulting in an increase in the ambient temperature of the sealing ring, which accelerates the aging of the sealing ring and shortens the servi...
