Shaft end generator for railway wagon

Abstract

The invention discloses a shaft end generator for a railway wagon. The shaft end generator comprises a stator, a rotor and a side cover; the stator is a semicircular ring structure matched with a bearing saddle and is arranged on the side surface of the bearing saddle through a shell of a semicircular cylinder structure; the rotor is arranged at the axle end of the axle through a bracket sleeve for replacing a front cover of a bearing; the side cover is arranged on the outer sides of the stator and the rotor; the side cover is in sealing connection with the bearing saddle, the shell and the axle bearing to form a sealing body used for containing the stator and the rotor. The shaft end generator can be applied to a railway wagon using three large-piece bogies, and has the advantages of thehigh reliability, the high protection, the no maintenance and the small bogie change.

Description

technical field [0001] The invention relates to the technical field of railway freight cars, in particular to an axle-end generator for railway freight cars. Background technique [0002] With the expansion of the operation scale of railway freight trains and the service area of ​​special vehicles, more and more monitoring or protection devices (such as electronic anti-skid devices, braking systems, axle temperature detection equipment, etc.) are widely used in the safety system of railway freight trains , and the power supply reliability of these devices has been perplexing the application of the safety system of railway freight trains. The traditional power supply method is that the locomotive supplies power to each freight car through cables. Due to the frequent marshalling of railway freight trains and the harsh operating environment, the power supply is reliable Therefore, it is a very marketable application research to solve the power consumption problem of the railway...

[0002] With the expansion of the operation scale of railway freight trains and the service area of ​​special vehicles, more and more monitoring or protection devices (such as electronic anti-skid devices, braking systems, axle temperature detection equipment, etc.) are widely used in the safety system of railway freight trains , and the power supply reliability of these devices has been perplexing the application of the safety system of railway freight trains. The traditional power supply method is that the locomotive supplies power to each freight car through cables. Due to the frequent marshalling of railway freight trains and the harsh operating environment, the power supply is reliable Therefore, it is a very marketable application research to install a power generation device separately on the railway freight car to solve the power consumption problem of the railway freight train safety system.

However, since most of the bogies of the existing railway freight cars are three-piece bogies with no axle box structure, the shaft end power generation schemes of the above patents are not applicable to the three-piece bogies.
