AI Technical Summary
Technical Problem
In hydraulic transmission systems, rotating seals wear out due to prolonged exposure to high pressure, affecting their service life and increasing maintenance costs.
Method used
The pressure of the clutch hydraulic fluid is adjusted based on the rotational speed of the transmission shaft, and the pressure on the rotating seal is controlled between an upper and lower threshold. A proportional valve is used to regulate the clutch piston pressure to reduce the resistance of the rotating seal.
Benefits of technology
It effectively reduces wear on rotating seals, extends their service life, and lowers repair and maintenance costs, while maintaining the normal function of the clutch.

Abstract
提供了用于湿式离合器压力控制的方法和系统，以减少变速器中旋转密封件的阻力和劣化。在一个示例中，方法可以包括基于变速器的轴的旋转速度来确定上限阈值压力、基于轴的旋转速度来确定下限阈值压力，以及将被施加到离合器的液压流体的压力调整为处于上限阈值压力与下限阈值压力之间。以这种方式，施加到离合器的液压流体的压力可以维持在这样的水平，即，允许通过湿式离合器的完全扭矩传递，同时减少在旋转密封件上的阻力。
