Abstract

PURPOSE:To increase strength and improve torsional rigidity by using a member in which continuous fiber impregnated with resin is wound around a flexible member which extends in one direction, at a certain angle to its extending direction, as the core member of a steering wheel. CONSTITUTION:Continuous fiber 4 impregnated with resin is wound around a flexible member 3 which extends in one direction, at a certain angle to the extending direction of the flexible member 3, which is used as the core member 2 of a steering wheel 1. Thereby, the flexible member 3 increases bending rigidity while the continuous fiber impregnated with resin increases tortional rigidity. Also, the charging of the core member into a steering-wheel mold 5 is quite easy due to its flexibility.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steering wheel for a first-class motor vehicle, and more particularly to a steering wheel using a steering wheel core made of fiber reinforced resin (F-P).

(Conventional O technology) Recently, there has been a tendency to use synthetic resin for the steering wheels of five vehicles such as automobiles in order to save money, but if the steering wheel is made only of synthetic resin, the strength will be low. not enough.

For this reason, generally, urethane at-fat or polypropylene at-fat is used as a reinforcing material, and a core material made of an iron rod or an iron pipe is used. Although it has been adopted, it has little light weight effect and also has problems in upward movement characteristics.

By the way, Ei! ! II# Permit Publication GB2004835A
As described in et al., a continuous fiber bundle made of carbon fiber, glass fiber, aromatic polyamide fiber, etc. is impregnated with epoxy resin, phenol resin, etc., and then rolled into a frame or mold. A method of manufacturing an MA body with excellent craftsmanship has been developed.

〃・If the above-mentioned steering wheel core material is manufactured by the manufacturing method of 47cFR fiber FbenP purchasing body, @
It is believed that it is possible to provide a steering wheel with improved vibration characteristics.

(Problems to be Solved by the Invention) However, when the core material of the steering wheel is made by the above method, the core material has a structure in which the resin-impregnated rim east is oriented only in the same direction and is attached by −3. When an external force is applied to the steering wheel, torsional torque is applied to the ring portion and spoke portions of the steering wheel, causing a problem in that the steering wheel is likely to undergo a large amount of deformation.

The present invention solves the above problems, and its purpose is to reduce the
The purpose of the present invention is to provide a steering wheel that has excellent vibration resistance, and particularly high strength and torsional rigidity.

(Means for Solving the Problems) In order to achieve this object, in the present invention, resin neck immersion continuous fibers 4 are attached to the flexible member 3 extending in one direction. The bottom of the groove is a steering wheel core material 2 made of a member wound at a predetermined angle with respect to the extending direction.

(Function) The above-mentioned groove bottom reduces the bending rigidity of the flexible member 3 and is attached to the flexible member 3 at a predetermined angle with respect to the direction in which the flexible member 3 extends. The resin-impregnated continuous fibers 4 increase torsional rigidity.

Furthermore, since the core material 2 is made of a flexible member 3 that extends in one direction and the resin-impregnated continuous fibers 4 are wound around it, it is possible to load the steering wheel mold 5 into the steering wheel mold 5 when making the steering wheel 1. The flexibility makes it extremely easy.

(Effects of the Invention) Therefore, according to the present invention, it is possible to provide a steering wheel 1 that has not only good ut'r but also good bending properties and good torsional properties.

In addition, loading the core material 2 into the steering wheel mold 5 is extremely easy, which improves workability and improves tffl properties.

(Example) Embodiments of the present invention will be described below based on the drawings.

In Fig. 1, reference numeral 1 denotes a steering wheel according to the present invention (resin m is not shown in the figure), and this steering wheel 1 is made of a core material such as 2VC urethane resin or polypropylene resin (the resin is not included in the stock). It has become a dormitory.

The core material 2 includes a flexible member 3 extending in one direction, and a resin-impregnated continuous material that is tightly wound around the entire length of the flexible member 3 at a predetermined angle with respect to the direction in which the flexible member 3 runs. It consists of 4 fibers. In this embodiment, the town investment member 3 includes:
A continuous fiber bundle 3 of resin-impregnated sand is used.
Examples of the continuous fiber include conventionally known fibers such as glass fiber and carbon fiber, and are not particularly limited. The thickness and diameter of the fibers used are not specified, but for example, the diameter of the glass fiber is about 13 to 23 μm, and the diameter of the carbon fiber is about 7 to 10 μm.
It is preferable to use a bundle of about 0 pieces. ″1fc,
The resins contained in the above-mentioned continuous region fiber bundles 3 include epoxy resins, unsaturated polyester resins, phenol-aluminum resins, etc., which are conventionally used in VC.

Glass fibers, charcoal fibers, etc., such as those used in the passing member 5, are used for the resin-metal fibers 4.
The 1 resin impregnated in the number 4 is the same as above, epoxy resin, unsaturated polyester 4, and phenol resin.

will be completed.

That's all - eA 6'! Although I have been described above, the present invention also includes the following modifications.

(2) The removable member 3 is made of a material that can be removed from the interior of the lance-impregnated slow-release fibers 4 wound around the flexible member 3 by heat or quality control, such as a forceps-type 21F alloy. Memory alloy may also be used, which makes it possible to use a medium-sized steering wheel1.
By manufacturing the steering wheel 1, the design of the steering wheel 1 can be further improved.

(2) The resin-impregnated continuous a-rutted fibers 4 may be wound double or triple around the flexible member 3.
