Abstract: The present invention relates to a thermoplastic resin composition which has an improved impact resistance while maintaining mechanical properties such as strength and rigidity. In the present invention, a thermoplastic resin (A) is mixed with a polytetrafluoroethylene-containing mixed powder (B) consisting of a polytetrafluoroethylene (b1) having a particle diameter of 10 ?m or less and an organic polymer (b2). In this case, the polytetrafluoroethylene-containing mixed powder (B) is mixed so that the amount of a polytetrafluoroethylene component is from 0.0001 to 20 parts by weight based on 100 parts by weight of the thermoplastic resin (A), and a polymer having an epoxy group was used as the organic polymer (b2). The thermoplastic resin composition of the present invention can be widely used in the fields of automotive parts, electric and electronic parts, and precision instrument parts.

Abstract: A suspension system component for use in association with a leaf spring eye wrap of a leaf spring is shown to include a generally rigid planar base portion and a generally rigid scarf gap cover portion extending from the base portion in a direction generally normal to the base portion. The scarf gap cover portion includes first and second cover portion portions extending in different planes and adjoined at a seam. The component further includes a generally rigid first stop portion formed as a peg-like structure extending from the base portion in the same direction as the scarf gap cover portion. The component also includes a generally rigid second stop portion formed as a curved engagement surface extending from the base portion in that same direction.

Abstract: A sealed spring suspension for a vehicle includes a threaded bearing made of a spring shackle bolt and a spring bushing; into a recess in either end of the bushing, a sealing ring is pressed, which has a resilient sealing portion with a ring or lip in radial contact with the flat sealing portions of the bolt. By virtue of the bolt thread located between these portions having flattened thread tops and thread bottoms, the ring lip is able to slide without being damaged along said bottoms when the bolt during mounting is threaded into the bushing.

Abstract: A separator pad is loosely positioned between a leaf spring end and a top wall of a mounting slot in a vehicle spring hanger. The separator pad is preferably slid between the spring end and the slot top wall when the load on the leaf spring is relaxed or removed. The separator pad is positioned relative to the spring hanger while the load is relaxed to allow for limited subsequent longitudinal movement of the pad when the load is reapplied and the vehicle is in use. The separator pad includes stop members thereon at opposite ends thereof respectively to engage the spring hanger or the spring end and limit further longitudinal pad movement in that direction before the pad falls out.

Abstract: An improved air spring suspension system which includes an air spring on each front spring of a vehicle. The air spring is secured juxtaposed the rear end suspension of each front leaf spring and includes slide pads on each surface of the rear support links. The slide pads and rear end of the springs are secured by a bolt having a self-locking nut and the support links have edges within which the slide pads slide in order to prevent side-to-side movement.
