STEERING DRIVE AXLE ASSEMBLY WITH AN IMPROVED SEALING STRUCTURE, CAPABLE OF REDUCING THE REPLACING COST OF A SUPPORT BEARING SINCE THE LIFESPAN OF THE SUPPORT BEARING IS LONG

摘要

PURPOSE: A steering drive axle assembly with an improved sealing structure is provided to reduce the steering force since the abrasion of a spindle does not occur and dust or foreign materials are not covered on a gap between the spindle and a wheel hub.;CONSTITUTION: A steering drive axle assembly(1000) with an improved sealing structure comprises a driving shaft(100), a spindle(200), a connecting part(300), a wheel hub(500), a support bearing(700) and a sealing part(800). The driving shaft is rotated by the power of the engine. The spindle maintains a given gap to the driving shaft and protects the driving shaft. The connecting part is connected to one end of the driving shaft. The wheel hub is installed on the outside of the spindle and is connected to the connecting part. The support bearing is installed between the spindle and the wheel hub and supports the spindle and the wheel hub. The sealing part prevents foreign materials from becoming covered on a gap between the spindle and the wheel hub.;COPYRIGHT KIPO 2011
