一种智能定充型液力偶合器
本专利技术涉及一种液力偶合器，具体地说是一种定充型液力偶合器，特别是涉及一种可在线实时检测定充型液力偶合器工况且方便液力偶合器拆卸或安装的智能定充型液力偶合器。
技术介绍
定充型（限矩型、普通型）液力偶合器因其具有其他传动方式所不具备的特性而被广泛应用。由于定充型液力偶合器是个封闭的传动元件，其运转工作时是不可能对其充液量进行调节的。在当定充型液力偶合器遇到工作机严重过载时会降低输出转速直至堵转（输出零传速）对整个传动系统实现限矩保护，并在长时间过载时随着其内部工作介质温度与压力上升，将通过易熔安全塞将工作介质喷泄出去，从而切断传动实现对整机的卸荷保护，或通过特制的防喷安全塞产生动作触发电器元件给出信号实现断电保护与声光报警。作为定充型液力偶合器对整机的过载终极保护，无论是通过安全塞喷液还是采用防喷安全塞都存在不足：当采用易熔安全塞喷液保护时，喷出的工作介质对现场环境有一定污染，且高温液体可能对周围人员造成伤害，恢复液力偶合器的运行必须重新充液和更换安全塞，操作比较麻烦；而采用防喷安全塞虽可避免工作介质的喷出，但因其动作温度设置较低（防喷...
