Suspension type drive device for electric frame

Abstract

The invention discloses a suspension type drive device for an electric frame, which comprises a traction electric machine, a gear box and a six-link mechanism that are suspended on a truck frame, wherein the traction electric machine is directly connected with a pinion shaft of a pinion in the gear box through an elastic coupling, the pinion is externally meshed with a bull wheel positioned in the gear box, a bull wheel core of the bull wheel is connected with a hollow shaft of the six-link mechanism through an end tooth transmission disk, and the six-link mechanism is connected with a wheel through six links. The traction eclectic machine, the gear box, the hollow shaft of the six-link mechanism, the traction eclectic machine, the elastic coupling and an electric machine suspension beam form an integral drive unit, one side of the drive unit is suspended on the beam of the truck frame through a suspension rod of the gear box in a swinging manner, and the other side is connected with the beam of the trunk frame through an electric machine suspension seat. The invention can solve the problem of transverse unstability of an express locomotive, and can greatly prolong the service life of a transmission gear and an electric machine bearing of a high-power locomotive.

Description

technical field [0001] The invention relates to a suspension type drive device for passenger electric locomotives, in particular to an elastic suspension type drive device. Background technique [0002] The bogies of passenger electric locomotives with a running speed greater than 120km / h generally use suspension drive devices, such as my country's SS8, SS9, SS7E electric locomotives, and DF11 diesel locomotives; the drive devices of these locomotives are rigid or directly connected to the steering wheel through rubber ball joints. Architecture rack. This type of driving device transmits traction through cantilever pinion and six-link wheel set hollow shaft, and the gearbox is a non-load-bearing structure. This type of driving device is used for both two-axle bogies and three-axle bogies, but through nearly 10 years of practical application of quasi-high-speed passenger electric locomotives and recent research, it When the speed is greater than 120km / h, there is a phenomeno...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an elastic frame suspension driving device that can not only solve the problem of lateral instability of high-speed locomotives, but also greatly improve the service life of transmission gears and motor bearings of high-power locomotives.
