Embodiment Construction

[0019] As shown in the figure: the light rail bogie of this embodiment includes a wheel frame 10, a wheel 20 mounted on the wheel frame, a power assembly 30 that drives the wheel to rotate, and a climbing auxiliary assembly connected to the front end and / or rear end of the wheel frame 40. The climbing auxiliary assembly includes a climbing auxiliary bracket 41 mounted on the wheel frame in a vertically swingable manner, and a climbing auxiliary wheel 42 rotatably mounted on the climbing auxiliary bracket. The climbing auxiliary component is used in conjunction with the wheels. The climbing auxiliary component can be installed on the front or rear end of the wheel frame alone, or can be installed on the front and rear ends of the wheel frame at the same time. When the light rail bogie is installed on the light rail, it will move forward along the light rail. The direction is the front, the length direction of the light rail is vertical, the width direction of the light rail is h...

Abstract

The invention discloses a light rail bogie. The light rail bogie comprises a wheel frame, wheels installed on the wheel frame, a power assembly driving the wheels to rotate, and a climbing auxiliary assembly connected to the front end and / or the rear end of the wheel frame. The climbing auxiliary assembly comprises a climbing auxiliary support installed on the wheel frame in a vertical swing modeand a climbing auxiliary wheel installed on the climbing auxiliary support in a running fit mode. According to the invention, the climbing auxiliary support can be driven to vertically swing; in the light rail climbing or downhill process, the climbing auxiliary support swings downwards, the climbing auxiliary wheel is pressed on the rail to increase a friction between the wheel and rail, overcomea wheel skipping phenomenon, improve the operational stability of the light rail and prevent safety accidents caused by slip; and when the light rail runs horizontally, the climbing auxiliary supportswings upwards to enable the climbing auxiliary wheel to be erected above the rail, and at the moment, the climbing auxiliary wheel is separated from the rail, so that the running resistance is reduced.

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. ACCIDENT. Contents of the invention [0003] In view of this, ...
