本文讨论并举例说明在汽车设计中万向节的选用问题。负载循环负载循环是选用的基本依据。负载循环可以称作“负载频谱”、“负载时间曲线”、“负载寿命图”或其它许多名称。”负载循环”是一个图表,表示汽车在各种扭矩和车速下的工作时间分别占总工作时间的百分率。汽车决不会全部时间都在低挡运行,若以此来选择万向节的话,万向节的尺寸就会过大。大多数汽车在苛刻的工况下仅工作一部分时间,而大部分时间是在不大苛刻的工况下工作的。各种的负载都会产生磨损和损伤;疲劳和磨损是累积的。每个工作小时都会有若干的
This article discusses and illustrates the use of universal joints in automotive design. Load cycle Load cycle is the basic choice of use. The load cycle can be referred to as “load spectrum”, “load time curve”, “load life diagram” or many other names. The “load cycle” is a chart that shows the percentage of the total working hours of a car at various torques and speeds. The car will not run at low gear all the time, so if you choose a universal joint, the size of the universal joint will be too large. Most cars work only part of their time under harsh conditions, and most of the time work under less demanding conditions. Various loads can cause wear and tear; fatigue and wear are cumulative. There will be a lot of work hours
