The wheel axle (1) comprises a support axle (2) extending in the transverse direction (D) with the wheel attachment (5; 6) near at least one end (3; 4) thereof, which at least one wheel mounting (5; 6) comprises a first auxiliary arm (13, 13') and a wheel mounting pivot axis (7) oriented in the transverse direction (D) is provided on a second auxiliary arm (24, 24'). The at least one wheel mounting pivot axis (7) is movable between two positions (9, 10) located apart in the longitudinal direction (L). A first position (9) is located in the longitudinal direction in front of the second position (10). The first auxiliary arm (13, 13') comprises a locking cam (29) which can be moved between a locking and unlocking position for positionally locking the second auxiliary arm (24, 24') in the locking position and positionally unlocking the second auxiliary arm (24, 24') in the unlocking position.
