Vehicle stabilizer

Abstract

A stabilizer bar is intended for use in a vehicle, and a torsion part of the stabilizer bar is fixed to the vehicle body by a fixing member. A resin sheathing is provided integrally on an outer peripheral surface of the stabilizer bar. The fixing member is composed of the sheathing, a rubber bush disposed on the outer periphery of the sheathing, and a mounting fixture for mounting the rubber bush on the vehicle body side so as to cover the outer periphery of the rubber bush. The sheathing and the rubber bush are immovably assembled to each other. Thus, there may be provided a vehicle stabilizer, highly durable, easily mountable and replaceable, low-cost, and highly operable.

1 . A vehicle stabilizer comprising a stabilizer bar, wherein:
 a fixing member includes:   a sheathing provided integrally on an outer surface of the stabilizer bar;   a rubber bush disposed on the outer periphery of the sheathing; and   a mounting fixture attached to a vehicle body in such a manner as to cover the outer periphery of the rubber bush; and   the fixing member fixes a torsion part of the stabilizer bar to the vehicle body and immovably assembles the sheathing and the rubber bush to each other.   
     
     
         2 . A vehicle stabilizer according to  claim 1 , wherein the sheathing is provided by injection molding on the stabilizer bar which is shot-peened before a coating process. 
     
     
         3 . A vehicle stabilizer according to  claim 2 , wherein:
 the sheathing has an outer surface on which a rugged configuration including irregularities along the circumference of the stabilizer bar is formed;   the rubber bush is provided with a through-hole having an inner surface shape corresponding to the rugged configuration; and   the rugged configuration permits the sheathing and the rubber bush to be assembled so as not to be movable relative to each other along the circumference of the stabilizer bar.   
     
     
         4 . A vehicle stabilizer according to  claim 2 , wherein an outer surface of the sheathing is concaved, convexed, or tapered along an axis of the stabilizer bar, the rubber bush is provided with a through-hole having an inner surface shape corresponding to the concave, convex, or tapered shape, and the sheathing and the rubber bush are assembled so as not to be movable relatively to each other in at least one direction along the axis of the stabilizer bar by the concave, convex, or tapered shape. 
     
     
         5 . A vehicle stabilizer according to  claim 2 , wherein the sheathing is provided with a collar portion extending radially of the stabilizer bar, and the sheathing and the rubber bush are assembled so as not to be movable relatively to each other in at least one direction along an axis of the stabilizer bar with the rubber bush in engagement with the collar portion.
