发明名称 STEERING APPARATUS HAVING SPLINED RACK-BAR AND RACK-BUSH
摘要 A steering apparatus having a rack-bar and a rack-bush with spline is provided to prevent torsional clearance of the rack-bush due to torsional load of the rack-bar by engaging a spline mountain with a spline valley. A steering apparatus having a rack-bar and a rack-bush with spline comprises a rack-bar changing the rotation motion into the linear motion of a steering wheel, a rack housing wrapping an outer periphery of the rack-bar, and a rack-bush placed at one end of the outer periphery in the rack-bar. The spilne is formed at the outer periphery of the rack-bar and at the inner periphery of the rack-bush corresponding to the spline formed at the outer periphery of the rack-bar. A spline mountain(310) formed on the outer periphery of the rack-bar and a spline valley(320) formed on the inner periphery of the rack-bush are in contact with each other. The spline formed on the inner periphery of the rack-bush and on the outer periphery of the rack-bar has a coating layer.
