Abstract

The elastic frame suspension mechanism of the locomotive bogie driving device of the present invention is composed of the driving device (3) and three frame suspension arms (2) with one end fixed thereon, and the other end of the suspension arm (2) passes through the rubber ball joint (1 ) and suspenders (4) are connected with corresponding frame beams (6). An oil pressure shock absorber or a lateral limit rod (5) is respectively arranged on the side of the driving device (3) of the end shaft and the intermediate shaft, and the two ends of the driving device (3) and the side frame ( 7) Connect up. The restraint between the driving device and the frame is partially released, so the lateral dynamic performance of the locomotive can be greatly improved, and the requirement of high-speed operation can be met.

Description

technical field

[0001] The invention belongs to the technical field of railway locomotives, and in particular relates to a novel elastic suspension mechanism of a locomotive bogie drive device. Background technique

[0002] The suspension mode of the bogie driving device is an important factor affecting the running quality and running speed of the locomotive. The suspension mechanism of the locomotive bogie driving device mainly adopts two methods: shaft suspension and rigid frame suspension. The axle suspension method is actually a kind of semi-suspension, that is, half of the weight of the driving device is hung on the frame of the bogie, and the other half is directly pressed on the axle, which will affect the driving performance of the axle. The maximum speed of the locomotive can only be Reach 140km / h. Although the rigid frame suspension method realizes the full suspension of the driving device, the maximum speed can barely reach 180km / h, but because the driving devic...
