Embodiment Construction

[0037] The core of the present invention is to provide a three-axle bogie and its motor suspension device. The motor suspension device realizes the elastic connection between the drive device and the frame by being hinged with the swing rod and the suspension seat, so that the drive device can be used during the operation of the bogie. The lateral follow-up relative to the frame improves the lateral dynamic performance of the bogie and avoids the lateral instability of the bogie when the locomotive runs at a high speed.

[0038] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] It should be noted that the orientation words "horizontal", "longitudinal" and "vertical" appearing in this article all refer to the horizontal, longitudinal and vertical directions of the track wh...

Abstract

The invention discloses a three-axle bogie. A driving device of the bogie comprises a motor, wherein a transmission shaft of the motor is connected with a pinion through a coupler; the exterior of the pinion is meshed with a gearwheel that is mounted on a hollow shaft; the hollow shaft is rotatably mounted at the outer part of the axle of the bogie in a sleeving way; the exterior of the hollow shaft is connected with a driving disc; the driving disc is connected with wheel pairs through force transmission pins; and a driving device is elastically suspended on the frame of the bogie through a motor suspension device. The driving device with the structure can simply and reliably drive the wheel pairs. The structure further facilitates the elastic suspension structure between the motor and the frame, enables most of the transverse inertia and the shaking inertia of the driving device to be decoupled with the whole frame, is beneficial to improve the transverse dynamics performance of the bogie, and avoids a transverse unstable phenomenon of the bogie.

Description

technical field [0001] The invention relates to the technical field of railway transportation equipment, in particular to a three-axle bogie. Background technique [0002] Railway vehicles generally include five basic parts: car body, bogie, coupler buffer device, brake device and vehicle internal equipment. As the supporting part of the car body, the bogie plays the role of increasing the load, length and volume of the vehicle, and increasing the running speed of the train. According to the number and types of axles, bogies can be divided into two-axle, three-axle and multi-axle bogies. The technology of high-power and high-speed three-axle bogies represents the highest level of development of railway vehicle bogies. [0003] The three-axle bogie mainly includes a frame, a driving device, a primary suspension device, a secondary suspension device, a traction device, a motor suspension device, and a braking device. The driving device is a device for driving the wheel shaft...
