VÉHICULE FERROVIAIRE AVEC DISPOSITIF À RESSORT D'URGENCE

摘要

The present invention relates to an emergency spring device, in particular for rail vehicles, comprising an emergency spring unit (107). The emergency spring unit (107) is configured to provide resilient emergency support of a wagon body unit (102.1) of a wagon body (102) of the vehicle (101) on a running gear unit (103) of the vehicle (101) at least in a direction of a height axis of the wagon body (102) in an emergency operation in case of a failure of a secondary suspension device (104) of the rail vehicle (101). The emergency spring device (105) further comprises a decoupling unit (110). The decoupling unit (110) and the emergency spring unit (107) are configured to be arranged kinematically in series between the wagon body unit (102.1) and the running gear unit (103). The decoupling unit (110) is configured to mechanically decouple the wagon body unit (102.1) from the running gear unit (103) about a decoupling axis of rotation (105.1) extending along a longitudinal axis of the wagon body (102).
