  • Patent number: 4491429
    Abstract: A bushing assembly incorporated in an eye of a suspension arm for an automobile includes a cylindrical member, a cylindrical rubber bushing adhered to the outer peripheral surface of the member and press fitted in the eye, and a cylindrical insert embedded in the bushing. The bushing is provided on each end with a flange extending radially outward and contacting each end surface of the eye when the bushing has been fitted in the eye.

  • Patent number: 4406176
    Abstract: In a rack and pinion type steering system with an energy absorbing mechanism, errors in axial dimensions of the steering shaft and column tube often make it difficult to fix the two parts to each other at two predetermined axially spaced positions. Such difficulty is eliminated by providing an elongated slot of a predetermined axial length in the column tube to allow a holding member to extend radially through the slot irrespective of the dimensional errors to fixedly connected the column tube to the steering shaft. In addition, a support member which is mounted on the steering shaft for assembling a bearing thereon is constituted by a single structure to preclude disconnection or disintegration of component parts caused by the thrust acting thereon and provided with claw portions or caulking wall portions for holding the bearing securely in position.

  • Patent number: 4269043
    Abstract: A coupling interposed between a driving shaft and a driven shaft for transmitting torque from the driving shaft to the driven shaft. The coupling comprises a tube which is non-circular in cross section, a solid body inserted in the tube to create a clearance having a certain width between the inner periphery of the tube and the outer periphery of the solid body and a plurality of impact absorbing members made of elastic material such as rubber and fixed to certain portions of the outer periphery of the solid body. The impact absorbing members are positioned so as to prevent contact of the inner periphery of the tube and the outer periphery of the solid body when torque transmitted from the driving shaft is under a predetermined level and permit contact of the inner periphery of the tube and the outer periphery of the solid body when the torque is at or over the predetermined level.
