Claims23
Axlebox-spring-unit of a railway bogie comprising at least one hydraulic spring having a housing being required for a functionality of said hydraulic spring and an axlebox, at least a part of said axlebox forming at least a part of said housing, and at least an elastomeric portion of a spring element of the at least one hydraulic spring being provided in a hydraulic fluid of the hydraulic spring.
Axlebox-spring-unit of a railway bogie comprising at least one hydraulic spring having a housing being required for a functionality of said hydraulic spring and an axlebox, at least a part of said axlebox forming at least a part of said housing, whereby a spring element of said hydraulic spring is directly connected to an upstanding wall of said part of said axlebox.
Axlebox-spring-unit of a railway bogie comprising at least one hydraulic spring having a housing being required for a functionality of said hydraulic spring and an axlebox, at least a part of said axlebox forming at least a part of said housing, whereby a spring element of said hydraulic spring is directly connected to said part of said axlebox and said spring element is secured to said axlebox via a sealing device.
Axlebox-spring-unit of a railway bogie comprising:
- an axlebox comprising at least one cup-shaped region;
- at least one hydraulic spring adapted to be connected to a frame of the bogie;
- a spring element of the at least one hydraulic spring being secured directly to the axlebox to define together with the cup-shaped region a volume for receiving a hydraulic fluid,
- wherein said hydraulic spring is secured to the axlebox by way of a sealing ring.
Axlebox-spring-unit of a railway bogie comprising at least one hydraulic spring having a housing being required for a functionality of said hydraulic spring and an axlebox, at least a part of said axlebox forming at least a part of said housing, and said part of the axlebox forms together with a spring element of the hydraulic spring a boundary that completely contains a hydraulic fluid of the hydraulic spring.
Axlebox-spring-unit of a railway bogie comprising at least one hydraulic spring having a housing being required for a functionality of said hydraulic spring and an axlebox, at least a part of said axlebox forming at least a part of said housing, whereby a spring element of said hydraulic spring is directly vulcanized to said part of said axlebox.
Axlebox-spring-unit of a railway bogie comprising:
- an axlebox comprising at least one cup-shaped region;
- at least one hydraulic spring adapted to be connected to a frame of the bogie;
- a spring element of the at least one hydraulic spring being vulcanized directly to the axlebox to define together with the cup-shaped region a volume for receiving a hydraulic fluid.
