A motor driven truck for radial vehicles comprising:
- frame means,
- means to pivotally attach a railroad vehicle body to said truck,
- at least two railroad wheelsets adapted to support said frame;
- said at least two wheelsets attached to said frame means for relative pivotal movement between each of said at least two wheelsets and said frame about first respective pivotal axes, whereby said wheelsets may move to a radial alignment when travelling on curved track,
- at least one motor supported by said frame,
- drive transmitting means connecting said at least one motor and one of said wheelsets said drive transmitting means comprising a flexible coupling to permit relative angular displacement between said at least one motor and said one of said wheelsets about a second axis the first axis of said one of said wheelsets coinciding with said second axis.
