Portuguese term

3° eixo de apoio direcional

Portuguese to English Tech/Engineering Automotive / Cars & Trucks Brazilian standard
"veículos não-articulados de transporte coletivo urbano de passageiros que possuam 3º eixo de apoio direcional"

The term also appears without "de apoio" later in the document: "dois eixos direcionais."

Turn-assist(ed) 3rd axle? Directional axle?

This is basically a third axle on a large bus or truck that is steerable to assist the vehicle in making tight turns. I can't seem to nail the English equivalent down.

Thanks in advance!

http://www.training.bova.nl/files/vdlbd/pdf/DD0282 The steered trailing axle makes manoeuvring at low speeds
(parking, tight corners, etc.) easier. At speeds above 30 km/
h, the trailing axle is automatically locked in the middle
position in order to guarantee the stability of the vehicle when
driving in a straight line.

trailing axle

Non articulated coaches over a certain length must be equipped with an actively steered rear axle known as a trailing axle. This greatly improves agility and considerably reduces the turning cicle. The third axle is also steered when reversing, making it far easier to manoeuvre while reducing tyre wear in the process.
