Railway truck having bolster-suspended traction motor
A railway truck is disclosed for use with a locomotive. The railway truck may include a first axle, a second axle, a plurality of wheels connected to each of the first and second axles, a frame connecting the first and second axles, and a bolster assembly pivotally connected to the frame. The railway truck may also include a traction motor configured to drive the first axle. The railway truck may further include a torque reaction link connected between an end of the bolster assembly and a side of the traction motor.
1. A railway truck, comprising:
a first axle;
a second axle;
a plurality of wheels connected to each of the first and second axles;
a frame connecting the first and second axles;
a bolster assembly pivotally connected to the frame;
a traction motor configured to drive the first axle; and
a torque reaction link connected between an end of the bolster assembly and a side of the traction motor and including a rigid member with a first pivot end and a second pivot end, wherein the first pivot end is configured to pivot in a first direction and is operatively connected to a bottom surface of the bolster assembly, and the second pivot end is configured to pivot in a second direction generally orthogonal to the first direction.
2. The railway truck of claim 1 , wherein:
the traction motor is a first traction motor;
the railway truck further includes a second traction motor configured to drive the second axle; and
the torque reaction link is a first torque reaction link and the railway truck further includes a second torque reaction link connected between the bolster assembly and a side of the second traction motor.
