Specific embodiment
The core of the utility model is to provide a kind of F joint for track panel of magnetic-levitation, to solve magnetic-levitation train in machinery
During braking, brake pad easily leads to the problem of impact when passing through rail gap.
In order to which those skilled in the art is made to more fully understand technical solution provided by the utility model, below in conjunction with attached
The utility model is described in further detail with specific embodiment for figure.
As Figure 1-Figure 4, the F joint for track panel for a kind of magnetic-levitation that the utility model embodiment provides, including the
One F types track 1 and the 2nd F types track 2 docked with the first F types track 1, the butt end of the first F types track 1 are provided with protrusion 3,
The butt end of 2nd F types track 2 be provided with 3 recess 4 that is adapted of protrusion, on the lateral surface and the first F types track 1 of protrusion 3
Braking surface it is concordant, the lateral surface of recess 4 is concordant with the braking surface on the 2nd F types track 2, and protrusion 3 position and damper brake
The position of piece 5 is corresponding.
The F joint for track panel of above-mentioned magnetic-levitation passes through the docking location setting protrusion and mating recesses in F type tracks
Structure not only contributes to assembling positioning during docking, and is designed to and the braking on the first F type tracks by the lateral surface of protrusion
Face is concordant, and the lateral surface of recess is designed to, and the position of protrusion and brake pad concordant with the braking surface on the 2nd F type tracks
Position is corresponding so that when brake pad is by rail gap (i.e. the docking location of the section of track), the rubbing surface of brake pad is protected always
Hold with first or the 2nd F type tracks be in contact, be not in the situation that brake pad is absorbed in rail gap, so as to effectively reduce machine
Brake lining is improved the service life of vehicle part and track, so as to reduce maintenance cost, is carried by the impact of rail gap when tool is braked
High system safety and reliability.
What needs to be explained here is that above-mentioned raised 3 position is corresponding with the position of brake pad 5 to refer to that brake pad passes through
When crossing raised position, the rubbing surface of brake pad can keep contact condition with the lateral surface of protrusion always.In addition it needs to illustrate
, the braking surface on the first F types track 1 refers to the first F types track to contact with the brake pad 5 on brake clamp 10
The outside magnetic pole of lateral surface, the lateral surface namely F type tracks；Similarly, the braking surface on the 2nd F types track 2 concordantly refers to the 2nd F types
Track is used for the outside magnetic pole of the lateral surface contacted with the brake pad 5 on brake clamp 10, the lateral surface namely F type tracks.
It is further to note that the matching relationship of above-mentioned protrusion and recess can be structure as shown in Figure 1-Figure 3, i.e.,
Protrusion and the structure for bilateral cooperation on the longitudinal direction of recess；Can also be as shown in figure 4, protrusion and the longitudinal direction of recess
Upper to coordinate to be unilateral, the opposite side on the longitudinal direction of recess is open structure.But either unilateral cooperation or bilateral are matched
The structure type of conjunction, when the first F types track and the 2nd F type orbital dockings, protrusion can be embedded in recess.
In some specific embodiments, above-mentioned raised 3 with the fit clearance of recess 4 include lateral fit clearance 6 and
Longitudinal fit clearance 7, wherein, longitudinal fit clearance 7 includes upper fit clearance 8 and lower fit clearance 9, by by upper fit clearance
8 and lower fit clearance 9 the plane of symmetry it is corresponding with the median plane of brake pad 5 so that when brake pad passes through rail gap, can make
The contact area of brake pad and the lateral surface of protrusion is more, so that when brake pad passes through rail gap, more smoothes out.And
The plane of symmetry permitted maximum deviation corresponding with the median plane of brake pad 5 is ± 10mm.
What needs to be explained here is that lateral fit clearance refers to along the direction of travel of levitation train (i.e. F types guide rail
Be laid with direction) protrusion and the fit clearance of recess, longitudinal fit clearance refer to along vertically on the direction of F type guide rails, protrusion with
The fit clearance of recess；In addition it should be noted that the above-mentioned plane of symmetry it is corresponding with the median plane of brake pad 5 it is permitted most
Large deviation is also only the preferable examples of the utility model embodiment, can also be according to actual processing energy in actual production process
Power selects other corresponding maximum deviation numerical value.
In addition, longitudinal fit clearance 7 is generally 0-1mm.Of course, it should be understood that the numerical value of above-mentioned longitudinal direction fit clearance
Also it is only the preferably citing of the utility model embodiment, can also be according to actual production machining accuracy and ability, selection pair
Other numerical value answered, such as 0.5mm, 1.5mm or 2mm etc..
During in order to ensure that brake pad passes through recess, the rubbing surface of brake pad can simultaneously with the lateral surface of protrusion and recessed
Mouthful lateral surface be in contact namely be in contact simultaneously with the first F types track and the 2nd F type tracks, the width design of recess 4 is into small
In the width of brake pad 5.It is appreciated of course that above-mentioned is only the preferable examples of the utility model embodiment, it can be with
Be the width design of recess 4 into the situation of the equal or slightly larger than width of brake pad 5, only the utility model preferably will be recessed
Mouthfuls 4 width design is into the width less than brake pad 5.Because by by the width design of recess 4 into less than damper brake
The width of piece 5 so that when brake pad is by the docking location of the first F types track and the 2nd F type tracks, can more smooth out.
In some more particular embodiments, above-mentioned raised 3 and the corner angle position of recess 4 be both provided with chamfering.It should fall
Angle can be rounded corner, and the radius of rounded corner is generally chosen for 1mm or those skilled in the art are for round and smooth mistake
Other used chamfering forms when crossing, such as chamfer.What needs to be explained here is that it is above-mentioned be only the utility model for
The citing of the radius of rounded corner according to practical condition and process requirements, can also select the half of other corresponding rounded corners
Diameter value.
The F joint for track panel of magnetic-levitation provided by the utility model is described in detail above.It needs to illustrate
, each embodiment in this specification described by the way of progressive, the highlights of each of the examples are with its
The difference of his embodiment, just to refer each other for identical similar part between each embodiment.
