A straddle-type monorail operating vehicle bogie

Abstract

The invention relates to an urban railway working vehicle bogie and particularly provides a straddle type single track working vehicle bogie, aiming at solving the problems that an existing bogie cannot meet the operation requirement that a single track road has more bends and slopes and is narrow. The straddle type single track working vehicle bogie comprises a framework, a secondary suspension device and a traction device, wherein the whole body of the framework is of an II-shaped all-steel assembly welding plate type box-shaped structure, and comprises a side beam, an end beam and longitudinal beams; motor brackets are fixed between the upper part of the side beam and the longitudinal beams respectively; the motor brackets are provided with walking wheel assemblies; four guide wheel assemblies are mounted in the middle of the side beam and two stable wheel assemblies are mounted on the two sides of the lower part of the side beam; the secondary suspension device adopts a secondary steel coil spring assembly; walking wheels are rubber steel wire tyres filled with nitrogen; guide wheels and stable wheels are additionally arranged so that a working vehicle can be safely and stably operated; the turning radius is small, the climbing capability is strong, the sticking force is high, the highest operation speed is 40km / h, the working speed is 5km / h and the rescuing speed is less than 5km / h; the straddle type single track working vehicle bogie has a simple structure, is convenient to maintain and has a reliable performance.

Description

technical field [0001] The invention relates to a bogie for an urban rail operation vehicle, in particular to a straddle type monorail operation vehicle bogie. Background technique [0002] With the rapid development of urban rail transit, the straddle-type monorail transit system has become an integral part of the urban comprehensive transportation system. As the only city in my country that has a straddle-type monorail traffic, Chongqing City must use special operating vehicles for the construction and maintenance of its operating line engineering system. Chongqing monorail road has many bends, steep slopes, and narrow roads. The maximum slope is 60‰, so the design of the truck's bogie is very important and special. [0003] At present, the bogies of subway vehicles and light rail vehicles used in urban rails are railway train bogies, and the running wheels are integral rolled steel wheels for railways, which cannot meet the operation requirements of PC beam tracks at all;...
