摘要:

针对法规要求和汽车轻量化的实际需求,从结构、材料、工艺三方面着手研发了一种轻量化停车楔,并根据技术要求对产品进行了性能检测和整车试验。结果表明,采用圆筒中空结构、选用聚丙烯/30%玻璃纤维(PP/30 %GF)复合材料一次注射成型,开发的新型停车楔满足技术要求规定的各项检测;质量仅有0.98 kg,相比原橡胶、金属材质的停车楔减重效果显著;具有良好的经济性和环保性,市场使用效果好。

Abstract:

A lightweight parking wedge was developed from the three aspects, including structure, materials, and technology based on the requirements of laws and regulations as well as the actual demand for automobile lightweight, and the resulting product was tested and analyzed from its performance to the whole vehicle according to the technical requirements. The results indicated that the developed parking wedge met the requirement of all the tests specified through adopting a cylindrical hollow structure and using the PP⁃matrix composite containing 30 wt % glass fiber. Its weight was only 0.98 kg, indicating a significant weight reduction effect compared to the original rubber and metal parking wedge, together with good economy and good environmental protection.

Key words: lightweight, parking wedge, compound material
