    • A tire inflation apparatus for inflating a tire mounted on a rim comprises an inflation head (40) mounted to a moveable inflation shaft (64) of a head position cylinder (42) and an assist cylinder (44) mounted to a frame member (62), with the frame member (62) and assist cylinder (44) positioned above the inflation location (34). The assist cylinder (44) includes a moveable assist shaft (68) operatively connected to the inflation shaft (64) by a moveable cross member (71) whereby the head position cylinder (42) and assist cylinder (44) cooperatively operate to selectively position the inflation head (40). The inflation head (40) is positioned in a retracted position (48) by vertical upward extension of the assist shaft (68) and positioned in a tire engaging position (50) by vertical downward retraction of the assist shaft (68). A fluid passage (52) in the inflation shaft (64) may deliver pressurized gas into a tire inflation cavity (54) of the inflation head (40) for inflating a tire when the inflation head (40) is sealed against the tire.
    • 一种用于给安装在轮辋上的轮胎充气的轮胎充气装置包括安装在头部位置筒体(42)的可移动充气轴(64)上的充气头(40)和安装在机架部件(62)上的辅助气缸(44) ),框架构件(62)和辅助缸(44)位于充气位置(34)的上方。 辅助气缸(44)包括通过可移动横向构件(71)可操作地连接至充气轴(64)的可移动辅助轴(68),由此头部位置气缸(42)和辅助气缸(44)协同操作以选择性地定位 充气头(40)。 通过辅助轴(68)的竖直向上延伸,充气头(40)定位在缩回位置(48)中,并通过辅助轴(68)的垂直向下缩回定位在轮胎接合位置(50)中。 充气轴(64)中的流体通道(52)可将加压气体输送到充气头(40)的轮胎充气腔(54)中,以在充气头(40)相对于轮胎密封时使轮胎充气。
