Abstract

The invention discloses a light rail bogie, which comprises a wheel frame, a wheel mounted on the wheel frame, a power assembly for driving the wheel to rotate, and a climbing auxiliary assembly connected to the front end and / or rear end of the wheel frame. The assembly includes a climbing auxiliary bracket mounted on the wheel frame in a vertically swingable manner, and a climbing auxiliary wheel rotationally fitted on the climbing auxiliary bracket. The climbing auxiliary bracket of the present invention can be driven to swing vertically, and when the light rail is climbing or descending, the climbing auxiliary bracket can be swung downward, so that the climbing auxiliary wheels are pressed above the rail to increase the distance between the rail and the rail. Friction, improve the wheel slipping phenomenon, improve the stability of light rail operation, and prevent safety accidents caused by skidding. When the light rail is running horizontally, the climbing auxiliary bracket swings upwards to make the climbing auxiliary wheel overhead above the track. At this time, the climbing auxiliary wheel Separated from the track to reduce running resistance.

Description

technical field

[0001] The invention relates to the technical field of rail transportation, in particular to a light rail bogie. Background technique

[0002] The bogie is one of the most critical components of a rail vehicle, used for load bearing, braking, traction, steering and other requirements of the train. With the acceleration of urbanization in our country, the problem of urban traffic congestion has become one of the problems faced by many large and medium-sized cities in China. Due to its small footprint, low cost, low energy consumption, and environmental protection, light rail is favored by city builders and has gradually become the main mode of transportation in cities. However, in some cities located in mountainous and hilly areas, the light rail inevitably needs to climb or go downhill due to topographical reasons, and the wheels and tracks should slip during the climbing or downhill process.
