Straddling type mono-rail bogie without primary spring

Abstract

The invention discloses a straddling type mono-rail bogie without a primary spring. The straddling type mono-rail bogie comprises a frame and further comprises a traction device, a basic braking device, a vibration reducing device, a gear case, stabilizing wheels, guiding wheels and walking wheels, and the traction device, the basic braking device, the vibration reducing device, the gear case, the stabilizing wheels, the guiding wheels and the walking wheels are arranged on the frame. A traction motor longitudinally arranged and the gear case are directly hung on the outer side of the frame in a rigidity manner. An output shaft of the gear case is connected with an axle through a split coupling. The frame is provided with a split type shaft box composed of an upper shaft box body and a lower shaft box body. The upper shaft box body and the lower shaft box body are detachably and fixedly connected. The upper shaft box body is fixed to the frame and used for installing the basic braking device. Wheel replacing is achieved without vehicle erecting, and daily maintaining work of a vehicle is greatly improved.

Description

Technical field [0001] The invention relates to a straddle-type monorail bogie without a primary spring, belonging to the technical field of bogies. Background technique [0002] Solving urban public transportation is a difficult problem that urban development must face. Urban rail transit has been widely used worldwide due to its advantages of green (low noise, low radiation, energy saving), intelligence, convenience, and large capacity. [0003] A monorail vehicle is a type of rail transit vehicle, which is different from the rail transit vehicle of the traditional steel wheel-rail rail transit system. It is a type of rail transit vehicle carried and driven by rubber wheels and walks on a special concrete pouring bridge. The monorail line has a small footprint, low vehicle operating noise, climbing ability (maximum gradient 60‰), and strong ability to pass small curves (radius R≤50m), so it is suitable for the development of urban public transportation. Monorail transportation ...

Problems solved by technology

[0008] In order to break the technical monopoly position of Germany and Japan in the field of monorail bogies, establish a technology platform of straddle monorail bogies belonging to my country, and meet the needs of the development of urban public transportation in mountainous areas, the present invention aims to provide a straddle type monorail bogie technology platform. A series of spring monorail bogies, aiming at the cumbersome problem of replacing rubber wheels with a bogie, realizes the replacement of wheels without a bogie, which greatly improves the daily maintenance of the vehicle
