Abstract

The invention relates to a low-floor tramcar power car bogie. The low-floor tramcar power car bogie is composed of a framework, wheel pairs, driving systems, primary suspension parts, secondary suspension parts, traction devices, brake systems, rim lubricating systems, sand scattering systems, stone removing devices and the like. The low-floor tramcar power car bogie adopts a traditional wheel pair structural mode; the traction devices of the low-floor tramcar power car bogie are arranged on the outer side of the framework in a skew symmetry mode; the driving systems are arranged on the outerside of the framework; and motors are suspended on the upper portions of framework side beams, and each wheel pair is driven by the corresponding motor. The low-floor tramcar power car bogie has the characteristics of simple structure, low manufacturing cost and low casting and welding requirements.

Description

technical field [0001] The invention relates to a tram bogie, in particular to a low-floor tram power car bogie. Background technique [0002] 100% low-floor trams are popular because they do not need to set up platforms and are convenient for passengers to get on and off. In 1990, the world's first 100% low-floor tram was officially unveiled in Bremen, Germany. Since then, urban trams have entered the era of 100% low-floor. The floor height of 100% low-floor trams is usually about 350mm, which is convenient for passengers, especially children, disabled people in wheelchairs, etc. to get on and off. At the same time, it is convenient for passengers to move in the car, reducing the time for getting on and off the car. By adjusting the marshalling method of trains, the traffic volume demands of different cities and lines can be met. Bogies are an important part of locomotives, trams and subways, and are key components for their operation, guidance, loading and vibration red...
