    • A release device for a tandem axle of a semi-truck is a compressible piston and cylinder, with the piston rod extending out of one end of the cylinder and biased into an extended position by a biasing mechanism such as compressed gas in the cylinder. A latch on the cylinder is releasably engageable with an indent on the piston rod to hold it in a retracted position. A hook on the cylinder engages over the handle of a manual release rod for a truck tandem axle, with an enlarged head on the end of the piston rod bearing against part of the frame adjacent the release rod with the piston rod in the latched, retracted position. Release of the latch puts biasing force on the piston rod, urging the cylinder outwardly away from the frame to pull out the release rod.
    • 用于半卡车串联轴的释放装置是可压缩的活塞和气缸,活塞杆从气缸的一端延伸出来,并通过偏压机构(例如气缸中的压缩气体)偏压到延伸位置。 气缸上的闩锁可释放地与活塞杆上的凹口接合以将其保持在缩回位置。 气缸上的一个钩子卡在用于卡车串联轴的手动释放杆的手柄上,活塞杆的端部上的扩大的头部抵靠与释放杆相邻的框架的一部分,活塞杆处于闩锁的位置,缩回 位置。 闩锁的释放在活塞杆上施加偏压力,将气缸向外推动远离框架以拉出释放杆。
