Air spring unit

An air-spring module for an air spring for a vehicle, comprising

• an air-spring module connection element as connecting part with the load to be suspended, and
• air-spring module bellows, wherein the air-spring module bellows are connected, on the side facing the air-spring module connection element, to the air-spring module connection element at least in an airtight manner, wherein the air-spring module has at least one connecting element for at least airtight connection of the air-spring module to a rolling piston, wherein the air-spring module bellows are arranged in an airtight connecting manner between the air-spring module connection element and the connecting element,
• wherein
• a plurality of guide ribs are arranged on the connecting element.

A method for producing an air spring for a vehicle, comprising the following steps:

• a) providing an air-spring module comprising an air-spring module connection element as connecting part with the load to be suspended, particularly a vehicle body or an axle of the vehicle and air-spring module bellows, wherein the air-spring module bellows are connected, on the side facing the air-spring module connection element, to the air-spring module connection element at least in an airtight manner;
• b) providing a rolling piston;
• c) connecting the air-spring module provided in step a) to the rolling piston provided in step b) and forming an at least airtight connection,
• wherein the air-spring module provided in step a) has a connecting element (5), wherein the connecting element is arranged on the air-spring module bellows on the side facing the rolling piston and the method in step c) is carried out by means of a connecting element directly adjacent to the air-spring-module-side rolling piston end at least in certain sections, wherein, with the connection in step c), the connecting element engages into the air-spring-module-side rolling piston end.

The use of an air-spring module and/or an air spring for a vehicle, comprising

• an air-spring module having an air-spring module connection element as connecting part with the load to be suspended, particularly a vehicle body or an axle of the vehicle and air-spring module bellows, wherein the air-spring module bellows are connected, on the side facing the air-spring module connection element, to the air-spring module connection element at least in an airtight manner,
• a rolling piston,
• wherein
• the air-spring module has at least one connecting element for at least airtight connection of the air-spring module to the rolling piston, wherein a plurality of guide ribs are arranged on the connecting element and the air-spring module bellows are arranged on the side facing the rolling piston on the connecting element, and the connecting element is arranged directly adjacent to the rolling piston at least in certain sections and the connecting element is placed onto the rolling piston.
