Traction bolster buffer structure for suspension type monorail train

Abstract

The invention discloses a traction bolster buffer structure for a suspension type monorail train. The structure comprises a coupler mounting seat plate, a traction beam, a buffer beam and a sleeper beam, wherein the lower end of the coupler mounting seat plate is connected to the front end of the traction beam, the front end of the buffer beam is fixedly connected to the traction beam and the coupler mounting seat plate correspondingly, and the rear end of the buffer beam is fixedly connected to the sleeper beam; the coupler mounting seat plate is made of an aluminum alloy plate; and the traction beam and an upper end beam are of an integrated structure, the traction beam is formed by adopting aluminum alloy extruding, and the lower portions of the two ends of the traction beam and a longitudinal beam of a vehicle body are fixedly connected in a welded mode. According to the traction bolster buffer structure for the suspension type monorail train, suspension mounting bases on a sleeperbeam are connected with a hanging bracket on a bogie together by connecting pins, the connecting pins are in transition fit with the suspension mounting bases, and is in clearance fit with the hanging bracket, bolt bases are welded beside the suspension mounting bases, and slots are used to penetrate downwards and are abutted against the connecting pins to be fixedly connected with the connectingpins, so that the rigid connection between the hanging bracket and the vehicle body through a mounting pin is realized, and the structure is stable.

Description

technical field [0001] The invention relates to the technical field of suspended monorail traffic, in particular to a traction pillow structure for suspended monorail trains. Background technique [0002] As the construction of urban rail transit extends from the main urban area to surrounding areas, and from first-tier cities to second- and third-tier cities, the demand for new standard rail transit systems with medium and low volumes is increasing. Thanks to this, domestic suspended monorail technology has been greatly developed. However, due to the late start of domestic suspended monorail, the lack of corresponding technical accumulation and practical experience, especially when it comes to the key parts of vehicle safety, its design scheme needs to be improved. and improve. [0003] The traction pillow structure of the suspended monorail train is used to connect the car body and bogie, car body and coupler, and is responsible for transmitting the traction power to the ...

Thanks to this, domestic suspended monorail technology has been greatly developed. However, due to the late start of domestic suspended monorail, the lack of corresponding technical accumulation and practical experience, especially when it comes to the key parts of vehicle safety, its design scheme needs to be improved. and improve

[0003] The traction pillow structure of the suspended monorail train is used to connect the car body and bogie, car body and coupler, and is responsible for transmitting the traction power to the car body. Therefore, the traction pillow is a component with complex forces and heavy loads , so in the design and manufacture process, it is faced with problems such as high structural strength requirements, complex processes, and difficult manufacturing

On the other hand, suspended monorail transportation, as a mode of transportation with medium and low traffic volume, has a relatively small car body, and the wheelbase and car length are only less than half of the subway car, so the external dimensions of the traction pillow are greatly affected. and because of the unique operation mode of the suspended monorail—the bogie is above and the car body is below—it faces the problem of lightweight
