ABSTRACT:
A coupler arm assembly is disclosed which includes a coupler frame with a coupler head and a channel. A hollow housing is defined between the coupler head and the channel. A knuckle is pivotally connected to the coupler head and movable between a coupled position and an uncoupled position. A core pin is received in the hollow housing of the frame. A first end of the pin selectively engages a detent of the knuckle and a second end of the pin extends away from the hollow housing parallel to the channel. The assembly includes two distinct uncoupling devices. The first device includes a solenoid disposed about an outer periphery of the coupler frame. The solenoid applies a magnetic force upon activation to move the pin from engagement with the knuckle. The second device includes a lever arm pivotally connected to the coupler frame adjacent a first end, a plunger adjacent a second end, and an uncoupler armature extending downwardly from the lever arm. The plunger passes through the channel and engages a bore formed in a block connected to the core pin. The armature is selectively moved from a biased upward position to a downward position where the plunger works in combination with the block such that the pin is no longer in contact with the knuckle detent.
