High-speed locomotive motor suspension device

Abstract

Provided is a high-speed locomotive motor suspension device. A motor 1 is in rigid connection with a gear case 2 and is connected with a front supporting base 3 through a bolt casing pipe 13 and an inside hexagonal bolt 5, hung on a framework front end beam 6a through the front supporting base 3 and connected with a motor hanging rod 7 through a back supporting base 4 to be hung on a framework cross beam 6b, the gear case 2 is hung on the framework cross beam 6b through a gear case hanging rod 8, a baffle 4a of the back supporting base 4 is clamped between transverse stopping bases 9 arranged on the framework cross beam 6b, and a certain clearance is kept. According to the high-speed locomotive motor suspension device, an elastic frame suspension mode is adopted in motor suspension, and therefore it is guaranteed that a locomotive has the good dynamics performance and the low wheeltrack dynamic acting force; by combining the transverse stopping function, low transverse vibration and the good transverse dynamics performance are guaranteed. The high-speed locomotive motor suspension device is simple in structure and reasonable in design and has the high carrying capacity and safety coefficient.

Description

technical field [0001] The invention relates to a high-speed locomotive motor suspension device. Background technique [0002] The function of the locomotive motor suspension is to suspend the traction motor on the bogie and prevent it from falling onto the track. Locomotives with different speeds and load levels have different requirements for suspension methods. The suspension mode of the motor is mainly divided into two types: shaft suspension (also known as rolling shaft-holding semi-suspension) and frame suspension (also known as full suspension). The typical shaft suspension structure is: the traction motor is installed on the bogie frame, and the motor shaft is parallel to the axle. One end of the motor is supported by a pair of bearings installed in the motor suspension system, and the axle rotates around the bearings. The other end is fixed on the bracket of the frame beam through the motor suspender. Typical structure such as figure 1 shown. [0003] In the d...

AI Technical Summary

Problems solved by technology

[0005] 2. The working conditions of main components such as traction motor, bearing and traction gear are bad

[0006] 3. The torsional elasticity driven by the rigid shaft suspension structure is poor, which often easily causes overload or even damage to the DC traction motor

The structure of the elastic shaft suspension is relatively complicated, and the cushioning effect is very limited.

[0007] 4. The shaft-suspended structure determines that it is only suitable for locomotives with speeds below 120km / h, and cannot meet the requirements of high-speed locomotives
