Embodiment 1

[0035] A method for making a lightweight composite thrust rod, such as figure 1 As shown, the thrust rod includes a peripheral layer reinforcement 11 located at the outermost layer and a long fiber reinforced thermoplastic composite material or a short fiber reinforced thermoplastic composite material injected into the outer peripheral layer reinforcement 11, and both ends in the peripheral layer reinforcement 11 There is a metal steel sleeve 12, and the metal steel sleeve 12 is internally pressed with a rubber metal ball hinge 13.

[0036] like figure 2 As shown, the outer peripheral layer reinforcement 11 is a continuous surrounding structure that is closed in the circumferential direction and is formed by winding a belt-shaped continuous fiber reinforced thermoplastic composite material, which provides integral support for the entire thrust rod 1. Because the entire outer peripheral layer reinforcement 11 When a continuous and complete material strip is wound into a whole...

Embodiment 2

[0045] The difference between this embodiment and the above-mentioned embodiment is that in this embodiment, the center body 22 is the mold core part that restricts the molding structure of the long fiber reinforced thermoplastic composite material or the short fiber reinforced thermoplastic composite material during the injection molding process, and the metal The steel sleeve 12 is used as the two ends of the central body 22, so the specific manufacturing method of the thrust rod 1 is as follows:

[0046] The first step: set up a heating device such as an infrared heating device, etc. near the tooling 2, while heating the belt-shaped continuous fiber reinforced thermoplastic composite material, winding multiple turns around the outer periphery of the center body 22 formed by the metal steel sleeve 12 and the mold core, Then use the cylinder 24 to push the pressing block 23 towards the central body 22 to press the continuous fiber reinforced thermoplastic composite material to...

Abstract

A method for manufacturing a lightweight composite thrust rod. Firstly, a tooling including a center body and a briquetting block is set, and then a strip-shaped continuous fiber-reinforced thermoplastic composite material is wound around the center body for multiple turns, and a briquetting block is used to press a The circumferentially closed continuous special-shaped peripheral layer reinforcement is then filled with long fiber reinforced thermoplastic composite material or short fiber reinforced thermoplastic composite material by injection molding inside the peripheral layer reinforcement, and finally rubber metal balls are hinged into both ends. Form a complete thrust rod. The thrust rod formed by this method has superior performance, higher strength, and can withstand greater tensile strength without being easily torn. At the same time, a U-shaped hemming structure is arranged on the edge of the outer peripheral layer reinforcement to ensure the welding of two different materials. The overall fatigue performance of the thrust rod is also superior.

Description

technical field [0001] The invention relates to a method for manufacturing a thrust rod, in particular to a method for manufacturing a lightweight composite material thrust rod. Background technique [0002] Thrust rod is an auxiliary element widely used in automobile suspension system, including rod body, both ends of the rod body have rod heads, and the rod head has a support shaft connected with the double axle of the car to transmit the longitudinal force or lateral direction of the vehicle. At the same time, it can also transmit forces and moments in other directions to ensure a definite motion relationship between the wheels and the body, so that the vehicle has good motion characteristics, preventing the body from excessive lateral roll when turning and improving the balance of the car sex. [0003] At present, in order to reduce the fuel consumption of automobiles, reduce exhaust pollution, and vigorously promote the lightweight of automobiles, lightweight thrust ro...
