About Double Convoluted Air spring

Double convoluted air springs are the simplest solution from a technical point of view for air-suspended secondary springs. As an elastic link between the bogie and railcar body, rolling bellows distance the railcar body to the platform and absorb track irregularities by minimising the transmission of vibrations.
