杜仲橡胶在汽车扭力梁铰接的应用研究

研究杜仲橡胶(TPI)与天然橡胶（NR）共混硫化胶性能及其在汽车减震制品扭力梁铰接中的应用。结果表明，在原天然橡胶体系中并用少量杜仲橡胶，可以在保持原胶料物理性能基本不变的情况下，大幅提高天然橡胶的伸张疲劳性能、耐屈挠性能和动态力学性能，并且能够显著改善汽车扭力梁铰接的耐疲劳性能，在汽车减震橡胶件的应用前景令人期待。

Research of applicating eucommia rubber in automobile torsion beam hinge

Torsion beam hinge plays an important role in automobile suspension. Performance of TPI/NR blends and their application on torsion beam hinge as automobile shock absorber product had been researched in this paper.Results showed that under the condition of keeping the physical properties of the raw material unchanged, the tensile fatigue properties,flex fatigue resistance properties and dynamic mechanical properties of the TPI/NR blends were highly improved when a small amount of eucommia rubber was mixed in the original natural rubber system. Fatigue performance of automobile torsion beam hinge had been improved for three times when TPI/NR blends were applicated in it.Application of eucommia rubber in automobile shock absorber products is well expected.
