具体实施方式
图1示出了具有车架15的作业车辆10。该作业车辆10被示为紧凑型履带装载机20。本公开考虑了其他类型的作业车辆10,例如包括滑移装载机和推土机。至少一个地面接合装置25联接至车架15,并构造成将车架15支撑在表面30上方,并使作业车辆10沿表面30移动。所示的地面接合装置25是一对履带35。地面接合装置25可以是轮子(未示出)。
操作员站40连接至车架15。操作员站40可以具有门(未示出)。
悬臂组件45联接至车架15。悬臂组件45包括联接至车架15的一对上连杆50。一对下连杆55联接至车架15。一对悬臂液压缸60联接至车架15,其中作业车辆10的每侧上一个悬臂液压缸60。悬臂液压缸60可以是液压致动器65或电子致动器70。一对悬臂臂架(boomarm)75联接至上连杆50和下连杆55并且以作业车辆10的每侧上一个悬臂臂架的方式定位。一对悬臂75与悬臂液压缸60连接。悬臂液压缸60构成为使悬臂组件45移动。
参照图2,附接件联接器80联接至悬臂组件45的远侧部分85。至少一个倾斜缸90联接至悬臂组件45和附接件联接器80,并构造成使附接件联接器80移动。倾斜缸90可以是液压致动器92或电子致动器94。倾斜缸90具有完全伸出的位置95(图3),中程位置100(图2)和完全缩回位置105(图4)。
继续参考图2,附接件110联接至附接件联接器80。附接件110包括联接至附接件联接器80的附接件框架115。附接件框架115具有下部120,上部125,前表面127和后表面130。后表面130具有上半部分135和下半部分140。参考图2,在附接件110的操作位置145中,后表面130向前方150倾斜,或朝向前进行程的方向倾斜,其中上半部分135位于下半部分140的前方150,这有助于在倾斜缸90处于完全缩回位置105时提高附接件110的提升高度,因为倾斜缸90从更多地延伸的中程位置100到完全缩回位置105具有更多的行程。请参见图4,在附接件110的升高位置155中,后表面130向后方160倾斜,或朝向后退行程的方向倾斜,后表面130的下半部分140位于上半部分135的前方150。
参考图5,接头165联接至附接件框架115的下部120和铲刀170。接头165具有下表面175和上表面180。参考图2,下表面175定位成与表面30相距一距离185。
继续参考图2,接头165可以是球形接头190。接头165可以在第一旋转轴线195处联接至铲刀170,并且至少一个偏转缸200可以在第二旋转轴线205处联接至铲刀170。偏转缸200可以是液压致动器202或电子致动器204。第二旋转轴线205可以位于第一平面210(图1)中。第一旋转轴线195和第二旋转轴线205可以在接头165的中心处或附近相交。第一旋转轴线195可以垂直于第二旋转轴线205。
铲刀170可以是推土铲刀215。推土铲刀215可以具有倾斜气缸90处于中程位置100的操作位置145(图2)和倾斜气缸90处于完全缩回位置105的升高位置155(图4)。
参照图2,偏转缸200可以联接至附接件框架115的下部120和铲刀170。偏转缸200的一部分225可以定位在接头165的上表面180(图5)的下方。
接头165的水平接头中心线230可以从偏转缸200的水平偏转缸中心线235偏移37毫米或更小。有利的是,这有助于减少跨功能的相互作用,例如在偏转运动期间不希望铲刀170倾斜,这利用作业车辆10的较少次通行就提高了对表面30的坡度的控制精度。替代地,可将偏转缸200定位为使得水平偏转缸中心线235和水平接头中心线230是重合的线条,其中它们之间没有偏移(未显示)以减少跨功能的相互作用。
参考图5,铲刀倾斜缸240可以联接至附接件框架115的上部125。铲刀倾斜缸240可以是液压致动器242或电子致动器244。参考图2,铲刀倾斜缸240可以在位于第一平面210(图1)中的第三旋转轴线245处联接至铲刀170。铲刀倾斜缸240构造成使铲刀170的一侧沿向上或向下方向倾斜。
可调节连杆250可以联接至附接件框架115的上部125。可调节连杆250可以包括用于手动调节的螺纹252。替代地,可调节连杆250可以是液压致动器253或电子致动器254。可调节连杆250可以在位于第二平面260(图1)中的第四旋转轴线255处联接至铲刀170,第二平面260位于第一平面210前方150且与之平行。第一平面210和第二平面260可以偏移30mm或更小,以减少跨功能的相互作用。
参照图6,替代地,可调节连杆250可以在位于第一平面210中的第四旋转轴线255处联接至铲刀170。可调节连杆250可以部分地或完全在铲刀170上方延伸。
