Abstract

PURPOSE:To provide increased strength, easy manufacturing and lower cost by integrally forming a steel member such as a bead or so with a leaf spring which is made of fiber reinforced resin without cutting the reinforced fiber. CONSTITUTION:Three projections 2a are formed on an eye 2, extending toward the end part 1a of a leaf spring 1 which is made of fiber reinforced resin while another projection 3a is formed on a slide piece 3, extending toward the lead spring 1. Reinforced fiber F such as carbon fiber or glass fiber is coiled on the projections 2a and 3a for fixing them and steel members S, that is, the eye 2 and the slide piece 3, are integrated into the spring with matrix resin P.

This invention relates to a fiber-reinforced resin leaf spring in which the eyepiece part and the steel member of the sliding side for the sliding sheet can be integrally molded.

It can be fixed to a fiber-reinforced resin leaf spring by integral molding or screwing.

The disadvantage was that it could not be done. Furthermore, since carbon fiber gin is extremely hard, a diamond tool is required, making it difficult to process and requiring a large number of machining steps, resulting in high costs.

For reinforced resin leaf springs, we have developed a system that allows these steel members to be extremely strongly fixed and integrally molded to the fiber reinforced resin leaf spring without cutting the valuable and expensive reinforcing fibers. This also eliminates the need for machine plate processing, increases the strength of the fiber-reinforced resin leaf spring, facilitates production, and reduces costs.

A protrusion is provided protruding toward the target, and a carbon fiber,
It is characterized by being formed by wrapping reinforcing fibers such as glass fibers and integrally molding the steel member.◎
The present invention will be explained below based on embodiments shown in the drawings. The fiber-reinforced resin leaf spring 1 is made by integrally molding the steel members S such as the eyelet part 2 and the sliding piece 3 for the sliding sheet.For example, from the eyelet part 2, the end of the fiber-reinforced resin leaf spring 1 Part 1a
Three protrusions 2a protrude from the sliding piece 3 toward the leaf spring 1 made of fiber-reinforced resin. , a reinforcing fiber F such as glass fiber is wound and fixed, and a steel member S, that is, an eyepiece 2 and a sliding piece 3 are integrally molded with a matrix resin P.
