Automotive lightweight rubber damping driving shaft supporting bearing manufacturing method

Abstract

The invention relates to an automotive lightweight rubber damping driving shaft supporting bearing manufacturing method. The method is characterized in that a rubber damping driving shaft supporting bearing comprises a main spring made of rubber, a supporting frame made of plastic and an insert made of metal. The manufacturing method includes steps: (1) vulcanization, to be more specific, subjecting the main spring to vulcanization in a vulcanization mould, applying 10-30MPa vulcanization pressure to the vulcanization mould, controlling the vulcanization temperature in a range of 120-130 DEG C, and setting vulcanization time in a range of 30-35min; (2) gluing, to be more specific, coating the surface of the vulcanized main spring with an adhesive, wherein an adhesive coating is in thickness of 10-15micron; (3) drying, to be more specific, drying the main spring coated with the adhesive in the step (2), wherein the drying temperature is 80-100 DEG C, and drying time is 15-25min.

Description

technical field [0001] The invention relates to the field of automobile parts manufacturing, in particular to a method for manufacturing a lightweight rubber shock-absorbing drive shaft support bearing for automobiles. Background technique [0002] The current energy shortage and environmental pressure are increasing, and the sustainable development of the automobile industry is facing challenges. As an effective means of energy saving, automobile lightweight technology has become one of the important research topics in the development of the automobile industry. At present, there are three main ways to realize the lightweight of automobiles: one is to optimize the structure of automobile chassis, engine and other parts, and the structural design mainly adopts methods such as front-wheel drive, high rigidity structure and ultra-light suspension structure; the other is to use In terms of materials, the weight of automobiles can be reduced through material substitution. In ter...

Problems solved by technology

[0004] At present, the process of making plastic-rubber composite parts is similar to that of traditional metal-rubber parts, but for automotive structural parts, this process has the following defects: According to the traditional process, the plastic bracket and the rubber main spring generally need to be vulcanized simultaneously However, due to the larger bracket and the more complex plastic structural parts compared to the metal structure, the cost of the rubber mold is higher, the edge sealing and pressure retention are more difficult, and the manufacturing process is also more difficult, especially when the plastic bracket and rubber are exposed to high temperature. Vulcanized together in the mold, during the long-term vulcanization process of 5-20 minutes, it is easy to cause degradation or shape change of the plastic, thereby reducing the performance and service life of engineering plastics
