Rail bogie for convertible rail-highway vehicle

A rail bogie for coupling to a convertible rail-highway vehicle for operating the vehicle in rail mode, comprising:

• first and second wheelset assemblies, each said assembly including an axle having rail wheels mounted to each end thereof;
• fist and second sideframe members coupled to and extending between said wheelset assemblies on each side of the rail bogie;
• a bolster assembly operatively coupled to and extending between said sideframe members;
• a coupling assembly mounted to said bolster assembly for coupling the rail bogie to an associated convertible rail-highway vehicle;
• a tubular pivot assembly mounted to and extending between said sideframe members for permitting relative pivotal movement thereof about an axis substantially parallel to said axles while substantially preventing relative longitudinal movement thereof;
• a spring assembly mounted to each said sideframe member so as to be disposed intermediate each said sideframe member and said bolster assembly respectively;
• a pneumatic brake assembly mounted to said sideframe members adjacent said wheels for braking said wheels;
• and
• said tubular pivot assembly including a reservoir for storing air for said pneumatic brake assembly.

A rail bogie for carrying a vehicle body comprising:

• first and second wheelset assemblies, each said assembly including an axle having rail wheels mounted to each end thereof;
• first and second sideframe members coupled to and extending between said wheelset assemblies on each side of the rail bogie;
• a bolster assembly operatively coupled to and extending between said sideframe members;
• a coupling assembly mounted to said bolster assembly for coupling the rail bogie to an associated vehicle body;
• a pivot assembly mounted to an extending between said sideframe members for permitting relative pivotal movement thereof about an axis substantially parallel to said axles while substantially preventing relative longitudinal movement thereof;
• said pivot assembly means includes a main gimbal tube element mounted at one end thereof to said first sideframe member and a tubular member mounted at one end thereof to said second sideframe member, said gimbal tube being rotatably received in said tubular member;
• a spring assembly mounted to each said sideframe member so as to be disposed intermediate each said sideframe member and said bolster assembly, respectively;
• a pneumatic brake assembly mounted to said sideframe members adjacent to said wheels for braking said wheels;
• and
• said main gimbal tube includes a reservoir for storing air for said pneumatic brake system.
