Description
Technical field
The present invention relates to a kind of axle sealing structures for automobile.
Background technology
Traditional axle sealing structure sets filler between sealing drum and shaft, is then extended using the pressing plate of left and right two
Into between sealing drum and shaft, filler is compressed, filler is made to be tightly attached to shaft, between eliminating between filler and shaft
Gap, so as to achieve the purpose that sealing.In traditional axle sealing structure, it is fixedly connected between two pressing plates of sealing drum and left and right, this
Cause when circular runout occurs for shaft, shaft can will be compressed positioned at the filler of one side, and the filler of shaft opposite side can become
Relaxation, so that filler is easily worn, and then leads to seal failure.
