Abstract
A secondary suspension for a rail vehicle truck is arranged between a suspension support connected to the car body of the vehicle and a spring support. It comprises several spring groups, whose spring elements each have a set of coil springs held by an upper and a lower spring plate and a metal-rubber spring element and are individually interchangeable. The spring elements are designed so that replacement of the spring groups can be carried out with the truck installed on the vehicle and without using a pressure stand or a lift. This goal is achieved by the fact that there are at least two diametrically opposed holder claws for spring tension holders on the upper and the lower spring plate of the spring groups, to which the spring tension holders are attached when the spring elements are compressed.
