Description

一种VLV阀用传感臂
技术领域
本发明涉及阀体传感臂。
背景技术
传感阀是铁路货车制动系统的关键部件之一，根据车辆载重在一定范围内自动、无级地调整制动缸的压力，明显缩小车辆在空、重车的不同载重状态下的制动率变化，从而有效地改善车辆的制动性能和列车纵向冲击力。
传感臂是VLV阀的外部关键部件，在车辆不同载重状态下通过传感臂的上下摆动来探测车辆的重量，进而实现向制动缸输送不同的压力空气。VLV阀的安装座组焊在摇枕上；限位挡板的安装座组焊在中交叉杆为其特意凸出的部位；限位挡板的高低调整通过上下移动限位挡板并紧固其安装紧固件来实现，其中VLV阀的传感臂插装在限位挡板的孔中，随着车辆载重的增加，VLV阀随着摇枕向下运动，限位挡板的位置固定不动，因此，随着车辆载重的增加，VLV阀的传感臂向上运动，增加制动缸输出压力，VLV阀的传感臂向上运动的距离越大，制动缸输出压力越大，直至最大压力。它的不足之处是：(1)车辆静止状态下摇枕档与侧架横向间隙与初始设置值不同时，制动缸压力与原设置的压力会出现较大的偏差；(2)安装限位挡板的紧固件中包含特制的止动垫圈，在组装、调整、检修及拆卸时困难，增加了成本及转向架摇枕弹簧下的重量；(3)中交叉杆为了限位挡板安装座的组焊需要，需特意伸长一块凸出部，此额外增加了中交叉杆本身的材料、制造难度、成本及转向架摇枕弹簧下的重量；(4)限位挡板结构复杂，增加制造难度及成本；(5)在车辆运行中实施制动时，由于摇枕档与侧架横向间隙处在不停的变化中，因此会导致制动缸压力不能稳定及由此产生的制动率不稳定。
发明内容
本发明的目的是提供一种可简化VLV阀传感臂的组装，解决制动缸压力不受摇枕档与侧架横向间隙变化的影响，减少车辆枕簧下的重量，提升车辆制动率的稳定性的VLV阀用传感臂。
本发明主要包括VLV阀体、传感臂、调节螺母、调节螺杆、触片。传感臂的一端弯折，在弯折处倒安装调节螺杆，在螺杆的螺纹上连接两个调节螺母，两个调节螺母分别置于传感臂弯折处的上下两侧。螺杆的下端与触片相接触。传感臂的另一端固定在VLV阀体上。
本发明在使用时，使安装后的VLV阀的传感臂逆时针转向90度指向中交叉杆，取消限位挡板、安装座、紧固件和中交叉杆凸出的安装部分。
本发明与现有技术相比具有如下优点：简化VLV阀传感臂的组装，解决制动缸压力不受摇枕档与侧架横向间隙变化的影响，减少车辆枕簧下的重量，提升车辆制动率的稳定性。
