Elastic hanging device for journal sticking installation motor

Abstract

Disclosed is an elastic hanging device for a journal sticking installation motor. The elastic hanging device comprises a motor end connection ring connected with the output end of a journal sticking motor rotor, an axle end connection ring connected with an axle, and elastic elements. The peripheral walls of the motor end connection ring and the axle end connection ring are provided with bosses distributed in a staggered mode at intervals. The elastic elements are fixed to the peripheries of the bosses in a coating mode and are provided with wedge-shaped blocks inserted into the gaps between the adjacent bosses. According to the elastic hanging device, the motor end connection ring is connected with the output end of the journal sticking motor rotor, the axle end connection ring is connected with the axle, the motor end connection ring and the axle end connection ring are connected through the elastic elements, the wedge-shaped rubber blocks are inserted into the gaps of the bosses and have good torque transmission, flexibility and vibration damping performance, the shifting ability is high, and power is transmitted to the axle by means of the wedge-shaped rubber blocks. Through the elastic hanging device, transmission is transmitted to the axle from the motor, a complex gear speed change mechanism is omitted in the middle, a large amount of structure space is saved, and unsprung mass is reduced.

Description

technical field [0001] The invention relates to an elastic suspension device for installing a motor with a shaft, which is used for transmitting the driving force of the motor to the axle. Background technique [0002] Due to the unevenness of the track line, rail transit vehicles based on the wheel-rail system will inevitably generate a large amount of vibration during the actual operation process. With the increase of the operating mileage, the state of the wheel-rail changes, such as rail corrugation, wheel out-of-round, The vibration will become more and more severe when the tread is peeled off and scratched. Rail vehicle suspension components are subject to various random vibration tests. The design of elastic suspension devices fully considers the operating environment of the vehicle. In order to reduce the impact of vibration on suspension components and the impact of fatigue life, it is applied to the structural design of rail vehicle suspension components. among. ...

AI Technical Summary

Problems solved by technology

At present, most traction motors in China are fixed on the bogie frame by means of frame suspension, and the vibration reduction function is realized through a series of suspension devices between the frame and the wheel set. However, with the continuous development of bogie technology, there is currently a drive The motor is directly mounted on the axle by holding the shaft. In this case, the vibration of the wheel set will be transmitted to the motor structure, which is a great test for the structural reliability and performance stability of the motor. Therefore, in the existing structural scheme Considering the design of the elastic suspension device, the vibration and impact of the motor will be reduced to the greatest extent.
