为了提高电力机車粘着重量的利用系数,值得研究的是欧洲现在广泛应用的所謂无枕梁轉向架的结构,关于这方面的資料非常缺乏,因此,最近与進行快速电力机車C1000设計的同时,对一些有关的問題,也進行了某些理論上的研究。 設计的結果表明,如果采用斜向牵引杆轉向架結构,电力机車能够有較高的粘着重量利用系数。在本文中,推導了決定斜向牽引杆水平倾角的公式,展示了如何進行粘着重量利用系数η的計算,并以电力机車C1000为例加以說明。此外,阐述了斜向牽引杆电力机車轉向架在曲綫內运行的情况,附加侧向力的產生和它对机車前轉向架上導向力的影响。
In order to improve the utilization factor of the adhesion weight of electric locomotives, what is worth studying is the so-called bolsterless bogie structure now widely used in Europe. There is a lack of information in this respect. Therefore, recently, with the C1000 design of a fast electric locomotive In the meantime, some theoretical studies have been conducted on some related issues. The results of the design show that the electric locomotive can have a higher coefficient of adhesion weight utilization with the diagonal drawbar bogie structure. In this paper, the formula that determines the horizontal inclination of the drawbar is derived, which shows how to calculate the adhesive weight coefficient η. The C1000 electric locomotive is taken as an example. In addition, the condition that the bogie of the towed-pole electric locomotive runs in the curve, the generation of additional lateral force and its influence on the steering force on the front bogie of the locomotive are described.
