现代发动机工况多变,转数一直在增高,因而对万向节传动装置的强度和寿命也提高了要求。传动轴所传递的最大扭矩,超过工作扭矩三倍。4500转/分的转速,9°的工作摆角,以及30°的最大瞬时摆角等,已是常见数值。而取消对万向节技术保养的要求,也是重要的。对允许噪音及振动量也提出了严格的限制。小客车万向节工作条件的变化情况,列于表1;载重车万向节工作条件的变化情况,列于表2。
Modern engine operating conditions change, the number of revolutions has been increasing, thus the strength and life of the universal joint transmission also increased requirements. The maximum torque transmitted by the drive shaft exceeds three times the working torque. 4500 rpm, 9 ° working swing, and 30 ° maximum instantaneous swing, etc., are common values. It is also important to cancel the requirement for universal joint technology maintenance. There are also strict limits on the amount of noise and vibration allowed. Changes in the working conditions of the passenger car universal joints are shown in Table 1. The changes in the working conditions of the truck universal joints are shown in Table 2.
