Rubber wheel suspension hinge pin type bogie integrating permanent magnet direct drive motor and axle box

Abstract

The invention provides a rubber wheel suspension hinge pin type bogie integrating a permanent magnet direct drive motor and an axle box. The rubber wheel suspension hinge pin type bogie comprises a bogie frame, permanent magnet motors, the axle box, rubber tires, guide wheels and a suspension beam. The bogie frame comprises a sleeper beam in the middle and two side beams perpendicularly connectedto the two sides of the sleeper beam, the permanent magnet motors are located at the front end and the rear end of the frame, each permanent magnet motor comprises a stator and a rotor, and motor shafts serve as rotors of the permanent magnet motors. The rubber tires are symmetrically arranged on the front side and the rear side of the bogie frame, the driving half shafts are arranged in the rubber tires, the suspension beam connecting seats are arranged on the lower portions of the sleeper beam, and the suspension beam is connected with the vehicle body through the suspension pin shafts. Themotor shaft and the driving half shaft are connected together by the rubber tires through the coupling so that the motor torque is directly transmitted to the tires, the gear box is omitted, the overall weight of the bogie is reduced, the size of the bogie is also reduced, and the driving efficiency is improved; meanwhile, the rubber tires are used and thus the climbing performance of the bogie isimproved.

Description

technical field [0001] The invention relates to the field of urban rail transit, in particular to a rubber-wheel-suspended vehicle hinge-pin bogie that adopts an integrated permanent magnet direct drive motor and an axle box. Background technique [0002] With the rapid increase of the number of private cars in the city, the urban traffic situation is declining day by day, and the environment is rapidly bad, so the urban rail transit system has been vigorously developed. The urban rail transit system has the characteristics of small footprint, low pollution, and large transportation capacity, among which a new type of rail transit-suspended rail transit has also emerged as the times require. The characteristic of suspended rail transit is that the bogie is wrapped in the track beam and located above the car body, so that the normal operation of the suspended traffic system can be guaranteed even in bad weather. Secondly, because the track beam is in the air, it occupies the ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing suspended monorail vehicles are still driven by the traditional three-phase AC traction motor with a gearbox. Such bogies are bulky and heavy, which is not conducive to passing small radius curves; Wheel rails limit the climbing ability of the bogie and increase the cost of building track beams
