AXLE HEALTH DISCRIMINATORY SAFETY TIMER ARRANGEMENT

摘要

An axle health discriminatory safety timer arrangement for a railway vehicle braking system including a first logic network connected to a pair of safety timers. The pair of safety timers being connected to a second logic network. The second logic network being connected to a pair of speed difference threshold detection sensors. The pair of speed difference detection sensors being connected to a third logic network. The third logic network being connected to a pair of output circuits. The pair of safety timers are also connected to a fourth logic network. A fifth logic network being connected to the third logic network and also being connected to a sixth logic network. The sixth logic network is connected to a pair of truck cutout circuits for nullifying the slip control on a multiple-truck vehicle for preventing an extended period of time of release of the brake cylinder pressure.
