Abstract
The utility model discloses a Bo bogie for an electric freight locomotive. The Bo bogie comprises a framework, two wheel pairs and two set of wheel pair driving systems driving the wheel pairs, wherein derailing protection strips crossing a rail are arranged on the framework at the side facing the rail. The distance between the derailing protection strips and the ground is smaller than the distance between the wheel pair driving systems and the ground. Since the derailing protection strips crossing a rail are arranged on the framework, and the distance between the derailing protection strips and the ground is smaller than the distance between the wheel pair driving systems and the ground, the derailing protection strips rides on the rail surface once the locomotive derails. Since the driving system is higher than the derailing protection strips the gear case, motor and other important parts in the driving system may not contact with the rail. The gear case, motor and other important parts in the driving system are effectively protected during a derailing accident.
