The invention relates to a transport vehicle having variable width and track width, a chassis (14) and at least one steering axle (16, 18, 20, 22), wherein the chassis (14) comprises two chassis parts (28) each carrying a row of bogies (60) arranged one after the other and are adjustable transverse

The invention relates to a transport vehicle having variable width and track width, a chassis (14) and at least one steering axle (16, 18, 20, 22), wherein the chassis (14) comprises two chassis parts (28) each carrying a row of bogies (60) arranged one after the other and are adjustable transverse to a vertical longitudinal medium plane (26) of the transport vehicle. According to the invention only a single longitudinally adjustable transverse track rod (72) is arranged between the two rows of bogies (60) connecting two bogies (60) of the one or the other steering axle (16, 18, 20, 22) and which length is adjustable according to a degree of enlargement or reduction of the width and track width.
