芬兰Rautaruukki公司正在试验160km/h货车转向架,而且认为该转向架在法国、德国、英国、斯堪的那维亚肯定会有市场。早在1988年该公司的运输技术研究室就与芬兰Valmet公司共同研制RRV-160型转向架,并一直与德国亚琛工业大学合作研究,还与芬兰奥卢大学研究高速转向架动力学。 1989年11月,该公司试验第一台转向架样机,试验结果表明,该转向架还需进一步改进。 RRV-160型转向架样机的设计轴重为16t、轨距1524mm,在上构架设有一根横梁和二个小构架,以形成一个轴距为1800mm的H型构架,横梁包括二个厚腹板和一个带
Rautaruukki, Finland, is testing a 160km / h truck bogie and believes the bogie will certainly have markets in France, Germany, the United Kingdom and Scandinavia. As early as 1988, the company’s transport technology laboratory worked with Finnish company Valmet to develop the RRV-160 bogie and has been working with RWTH Aachen to study and research high-speed bogie dynamics with Oulu University in Finland. In November 1989, the company tested the first bogie prototype and the test results showed that the bogie needed further improvement. The model RRV-160 bogie has a designed axle weight of 16t and a gauge of 1524mm. A cross beam and two small frames are provided on the upper frame to form an H-frame with a wheelbase of 1800mm. The cross beam includes two thick webs And a band
