Embodiment Construction

[0033] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0034] Such as figure 2 As shown, a kind of rim lubricating device provided by the present invention is installed on the frame 18 of the bogie, and a rim lubricating device is installed in front of the wheel 1 .

[0035] Such as figure 2 and image 3 As shown, a wheel rim lubricating device provided by the present invention includes two lubricating sticks 2, and the two lubricating sticks 2 are respectively in contact with the wheel rim root area 3 and the wheel rim outer surface area 4 to achieve lubrication, which is used to reduce the rim root area and the outer side area of ​​the rim. In this embodiment, two lubricating rods 2 are preferably installed in two lubricators 5 respectively.

[0036] Such as Figure 4 As shown, the two lubricators 5 have the same structure. The lubricator 5 includes a guide tube 6, the lubricating rod 2 is ...

Abstract

The invention relates to a rim lubrication device, a rim lubricator and a bogie. The rim lubrication device comprises two lubrication rods. The two lubrication rods make contact with a rim root area and a rim outer side face area correspondingly to achieve lubrication. According to the rim lubrication device, the characteristic that the wear rate of the rim outer side face area and the wear rate of the rim root area are different is fully considered, and the two independent lubrication rods are adopted for lubricating the rim outer side face area and the rim root area correspondingly; the size of each lubrication rod, the action angle of each lubrication rod and the corresponding lubrication area and the acting force of each lubrication rod can be independently designed so that the requirements for different wear rates of the rim outer side face area and the rim root area can be met well. The rim lubrication device has the advantages that the lubrication areas are accurate, the utilization efficiency of the lubrication rods is high, and economy is good.

Description

technical field [0001] The invention relates to a bogie, in particular to a wheel rim lubricating device and a wheel rim lubricator installed on the bogie, and also to a bogie equipped with the wheel rim lubricating device, belonging to the technical field of rail vehicle manufacturing. Background technique [0002] When the train runs to a small curve section, the rim of the guide wheel on the outer rail side will be in contact with the gauge angle / gauge surface of the rail. Due to the large contact pressure and accompanying impact, and the large sliding velocity component in the contact spot, the It will lead to severe wheel and rail wear, and at the same time, it will increase the running resistance of the train and bring about problems such as noise pollution. With the development of high-speed and heavy-duty railway transportation, the wheel-rail contact conditions have further deteriorated, and the problem of wheel-rail wear has become more and more serious. This has l...
