Two gas circuit slippages ring

The utility model discloses a two gas circuit slippages ring, let two two gas circuit slippages ring covers on gas axle body, make two gas circuit slippages ring the first from left right side next -door neighbour set up, left two gas circuit slippages ring friction piston is close to with the friction ring on right side, let and to rub the air supply duct of the piston hole at piston and sideslip piston place and connect with solitary gas supply system respectively, the function that alright realization locking force and tensile force were controlled respectively, the steerable locking force of sideslip piston, and the friction piston can with the friction ring butt, thereby it realizes the control tensile force to produce frictional force. The utility model is used for the slippage axle. 本实用新型公开了种双气路滑差环，让两个双气路滑差环套在气轴本体上，使得双气路滑差环左右紧邻设置，左侧的双气路滑差环摩擦活塞与右侧的摩擦环紧邻，让将摩擦活塞和横移活塞所在的活塞孔的供气道分别用单独的供气系统连接，便可实现锁紧力和张紧力分别控制的功能，横移活塞可控制锁紧力，而摩擦活塞可与摩擦环抵接，从而产生摩擦力实现控制张紧力。本实用新型用于滑差轴。
