Power is there are mainly two types of the technical solutions of power source.It is approximate permanent one is being provided by the torque spring of lubrication block (stick) cartridge exterior
Determine pulling force, be converted into constant force to be applied to the constant pressure lubricated on block (stick) by wirerope, directive wheel, makes to lubricate block
(stick) is contacted with wheel rim；Another kind is that spring one end is fixed on push rod front end, and the other end freely discharges, outside sleeve spring box
With sleeve, first insertion lubrication block (stick), is then inserted into sleeve for push rod, and spring natural drawing generates lubrication block (stick) rear portion permanent
Constant-pressure contacts lubrication block (stick) with wheel rim.
Although different from above two scheme structure, all there is following technical problem in them: 1. but due to
They are all using the elastic pressure of spring as power source, and former capital not can avoid solid stick and persistently be extruded on wheel rim, are caused
The problem of wheel rim transition lubricates；2. in rail vehicle operational process, due to the swing and vibration of wheel, wheel rim also has lubrication block
Reversed active force and collision；3. lubricating block to the pressure transient of wheel rim, in some instances it may even be possible to be separated with wheel rim, lead to solid lubrication
The coating effect of agent is affected；4. solid lubrication device is mounted on rail vehicle truck, in track vehicle operation
In, bogie and spring are possible to the case where resonating, and cause spring failure, cannot effectively squeeze lubrication block and carry out to wheel rim
Lubrication；5. there are the lubrication block price height of high lubricating effect for solid wheel flange lubricating technology, and connect due to lubricating block with wheel rim whole process
It touches and causes lubrication cost higher.
