pivot cross-beam
Explanation:
'pião' is usually some kind of 'pivot' or 'rotating part'. It probably refers to the cross-beam under the wagon (or on the bogie) that carries the 'bolster' (vertical pivot).

http://en.wikipedia.org/wiki/Bogie
The connections of the bogie with the rail vehicle allows a certain degree of rotational movement around a vertical axis pivot (bolster), with side bearers preventing excessive movement. More modern bolsterless bogie designs omit these features, instead taking advantage of the sideways movement of the suspension to permit rotational movement.[
