分との間の音響伝達作用を行う。Metal leaf springs are known and widely used, especially in the automotive field, for suspending a motor vehicle body to an axle structure for a wheel. Such metal leaf springs are heavy and add to the weight of the vehicle, thus increasing the energy required to propel the vehicle. Moreover, metal leaf springs are made from multiple spring plates, sometimes even ten spring plates, which must be connected to each other. Adjacent spring plates tend to generate noise and friction between the spring plates when the leaf springs are bent, accumulate dust and moisture, and are susceptible to corrosion. The metal leaf spring also performs a sound transmission function between the suspended body part and the suspended body part of the automobile.

空洞が確実に樹脂で充満される。This object of the invention is achieved by a leaf spring for suspending structures relative to each other, in which the elongated unitary members are made of a large number of parallel fiber strands within a resin polymer matrix. Ru. The strands mainly extend in the longitudinal direction within the main body, and are made of resin.
It is distributed almost uniformly within the IJ box. The non-metallic elongate member has metal attachment members at both ends thereof and a mounting assembly supported by the elongate body member at an intermediate portion between the ends. Both the end attachment members and the mounting assembly are attached to the elongated member to avoid stress concentrations and contribute to the durability and function of the leaf spring. The method of manufacturing leaf springs is to place the fiber strands in a generally longitudinal direction within the leaf spring such that the fibers are arranged with a substantially constant density in the cross section at any point along the length of the leaf spring. Includes distributing. The leaf spring manufacturing device includes a plastic mold having resin clasps at both ends,
The resin retainer serves to retain the resin within the mold as the mold halves reach the closed position under pressure, thereby ensuring that the cavity of the mold is filled with resin.

トランド分布をもたらすことが可能である。The spring body member /2 is made of a number of continuous strands, for example made of glass fibers, arranged parallel to each other in a matrix of a resinous polymer, such as epoxy. As is clear from Fig. 2, the outer shape of the spring body/2 is thickest at a point midway between its two ends, that is, its height in the vertical direction is highest, and thinnest at both ends. There is. The spring body /2 has a constant cross-sectional area over its entire length. This is because the thickness of the spring body/U changes, as is clear from Fig. 1 and from the comparison of the cross sections of the spring body/U in Figs. , the spring must be narrow in the center and wide at both ends. Such a constant cross section,
By keeping the reeds throughout the length of the spring body, it is possible to use continuous strands to provide the same number of strands in every cross-section, and at the same time to provide a constant strand distribution. be.

うに付勢する。The invention also relates to a method and a device for manufacturing the spring body/2. First, in FIG. 7, a continuous strand of fiberglass θ is pulled out from a roll, passes through 6 containers containing liquid resin 6g, and reaches a winding frame 6g. As is clear from FIG. 9, the winding frame Og is generally rectangular. The frame Ag has side members 70 which are interconnected by transverse end elements 72. The side piece 70 fits into two tubular side pieces 7 which are connected to each other by a lateral end element 76 . The two tubular members 7 have inside them a pair of springs 7g which act on the ends of the smaller diameter tubular side members to separate the end elements 7.2 and 7 from each other. to energize.

and 7 is wound up. During such winding, the frame 6g can be rotated in a known manner, either manually or by power means (not shown). Frame Og
is rotated a predetermined number of times to obtain the desired fiber strand to resin ratio in the finished product. Multiple wraps are required; in one spring configuration, leaf springs with a cross-sectional area of less than 3 square inches may require more than 200 wraps formed from two long strands. Ta. The winding of the strand is carried out in such a way that the fibers are evenly distributed over a width corresponding to the maximum width of the spring body 7.2 on the frame bg. After winding is completed, the cranno element or screw go is loosened, so that the spring 7g tensions the strands, keeping them under some tension and parallel to each other.

及びファイバー材料は除去される。The holding operation is carried out by placing the frame Og around the lower mold 9'l and placing the filament wound on the frame in the lower cavity. The ends of the lower mold 9g at both ends of the cavity 7B have clasps or constrictions 9g, which extend in the lateral direction of the cavity 9B. By placing the frame 4g around the nine lower molds, the strands come out from the end of the cavity qB. When the upper mold 92 is lowered into position, the fiber strands as well as the liquid resin 6 are pressed within the cavity 9. The strands pass through the ends of the closed mold and over clasps '7g, which act to receive resin from cavity 9A and prevent resin from escaping. Mold members 9.2 and q4 are heated to a temperature of approximately 3000F while the resin cures. Excess resin and fiber material formed at the ends of 72 is removed sufficiently to allow the resin to be handled.

The leaf spring mentioned. αη An elongated glass fiber strand is immersed in a liquid resin and the dipped strand is placed in an elongated cavity of a plastic mold, with the glass fiber strand being uniformly distributed in the longitudinally continuous cross section of said cavity and A method for manufacturing a special spring, which comprises: loosing a length of glass fiber strand V in a cavity of a plastic mold, and keeping the mold closed until the resin hardens. 78. The method of claim 77, wherein the resin cured middle-aged model is maintained at a temperature of 2 degrees Fahrenheit. (19+ If the width of the leaf spring is varied and the glass fiber strands are arranged in parallel relation to each other, then the camo fiber strands are formed in a pattern less than or equal to the maximum width of the leaf spring before placing them in the cavity of the molding mold. 77. The method of claim 77, wherein the glass fiber strand is subjected to a tensile force during pressing in a mea. 01 ) Claim 77, which dams up the liquid resin at both ends of the elongated cavity in the molding mold, thereby preventing the liquid resin from escaping and performing void-free molding.
The method described in section. 78. The method of claim 77, wherein the tape of glass fiber strands is arranged in layers with respect to each other. 231. A method according to claim 1, wherein the layers of tape 0 are arranged in the cavity in layers, with the -I part and the lower layer being the longest and the adjacent layers being progressively shorter. (Incorporated) all an elongated rectangular frame, means for biasing opposite ends of the frame away from each other, and means for rotating said frame about an axis intermediate between the ends. means for supporting; a reel for supplying a continuous glass fiber strand to the frame while tensioning the fiberglass strand by the end of the frame; and a pair of reels forming a cavity for forming a leaf spring. a press having a joining member, the frame having a width greater than the mold, and a joining member of the press for accommodating the strand in the cavity while retaining the strand in the frame; A leaf spring manufacturing device characterized in that these are mutually separable. Q51. Apparatus according to claim 1, including means for holding the ends of the frame in fixed but releasable relation as the strands are hung over the frame. (b) The joint member of the press has clasps at both ends of the cavity and engages with the strand to hold the uncured resin in the cavity under pressure until it is cured. Equipment described in Section.
