1. An air-suspension module for a rigid axle of a commercial motor vehicle, comprising an air-bellows mount and an air-bellows module supported on the air-bellows mount in the operational state of the air-suspension module, the air-bellows module having an air-suspension bellows designed to change its shape and a supporting body connected to the air-suspension bellows, one of the components of the air-bellows mount and the supporting body having a coupling projection protruding along a virtual projection path, which in the operational state of the air-suspension module engages with a coupling recess formed on the respectively other component of the air-bellows mount and the supporting body along the projection path, a translatory relative movement of the supporting body, in the operational state of the air-suspension module, being physically limited relative to the air-bellows mount, orthogonally with respect to the projection path and in a direction along the projection path,
wherein one of the components of the air-bellows mount and the supporting body has a latching body and the respectively other component of the air-bellows mount and the supporting body has a latching recess such that in the operational state of the air-suspension module the latching body is in a form-locking latching engagement with the latching recess, so that a translatory relative movement of the supporting body relative to the air-bellows mount is physically limited in the two opposite directions along the projection path wherein at least prior to an insertion of the coupling projection into the coupling recess and thus prior to establishing the latching engagement, at least an engagement section of the latching body, designed for the direct form-locking engagement with the latching recess, is preloaded towards its engagement position and is displaceable from the engagement position against this preload,
wherein the engagement section is preloaded by a spring towards the engagement position,
wherein the latching body is the spring and the engagement section is a section of the spring, and
wherein the spring is a bow spring having two spring legs situated opposite each other across a spring gap and connected to each other by a spring bow, at least one engagement section being formed on each of the spring legs.
