| 中文摘要: |
| 在不改变铁路轨道车用液力变速器原有性能和单级两相三元件液力变矩器结构的基础上，通过加装变矩器离心单向阀和供油控制阀，实现了对变矩器充、放油的控制和对变矩器输出力矩的控制，使液力变速器在一档起步和空档运行过程中输出力矩平稳上升，实现铁路轨道车的平稳起步，消除了起步冲击和空档走车现象，大幅度提高了舒适性和安全性。该缓冲装置结构简单、性能可靠、操作方便，还能够广泛应用于其他特种车辆。 |
| 英文摘要: |
| Without changing original function of hydraulic transmission used for railcar and basic structure of traditional hydraulic converter, the device can control the course of filling and draining oil of hydraulic converter for controlling output torque of the hydraulic converter through adding centrifugal one-way valve and supply-oil control valve, which can enhance output torque of hydraulic transmission stably and softly during transmission starting up in 1st forward range and working in neutral, ensuring railcar starting up steadily, preventing it from striking in 1st forward range and moving in neutral. It can improve comfort and security of railcar extremely. The character of the device lies in its simple structure, stable performance and convenient operation, and it can be also used in other specialized vehicles. |
