Solid wheel rim lubricating device and lubricating method

Abstract

The invention provides a solid wheel rim lubricating device, and belongs to the technical field of rail vehicles, the device comprises a lubricating device main body, an electric-air conversion valve,an acceleration sensor and a control module, wherein a cavity for accommodating a lubricating assembly is arranged in the lubricating device main body; one end of the lubricating device main body isprovided with an opening for communicating the cavity with the outside and allowing the lubricating assembly to pass through; the other end of the lubricating device main body is provided with a firstvent hole for communicating the cavity with the outside; an air outlet of the electric-air conversion valve is communicated with the first vent hole through an air outlet pipe; an air inlet is communicated with an air supply pipe; the acceleration sensor is used for monitoring the axial acceleration of a wheel; and the control module is respectively electrically connected with the electric-air conversion valve and the control module. The invention also provides a solid wheel rim lubricating method. According to the solid wheel rim lubricating device and the solid wheel rim lubricating method,the risks of phenomena such as overlubrication of a wheel, fracture of a lubricating block, failure of a spring and the like are reduced, and meanwhile, the use cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and more specifically relates to a solid wheel rim lubricating device and a lubricating method. Background technique [0002] During the operation of the subway train, the wheels and the track are in contact with each other, especially when the vehicle enters a curve or a switch, the wear of the wheel rim is more obvious. In recent years, the rapid development of subway rail transit has greatly relieved the city's traffic pressure, but there are many curves on the rail lines, especially small radius curve lines, which make the wear problem more prominent, which not only shortens the service life of wheels and rails , also increased energy consumption. Based on the consideration of the above problems, basically every bogie of the subway vehicle is equipped with a rim lubrication device, and the use of the rim lubrication device can not only effectively solve the serious problem of wheel-rai...
