Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing, to the present invention into
Row is further described.
Embodiment one
As shown in Figure 1, 2, 3, the rack rails train driving mechanism of the switching of axial direction anticreep zero defect disclosed in the present embodiment, including it is symmetrical
Two driving units being arranged, driving unit include driving motor 3, traveling wheel 5, driving gear 11, first clutch 4, second
Clutch 8, horizontal axis 2, vertical pivot 10 and intermeshing first bevel gear 6 and second bevel gear 9, the fixed peace of first bevel gear 6
Mounted in one end of horizontal axis 2,2 other end of horizontal axis is connected with brake disc 1.
Driving gear 11 is fixedly mounted on the lower end of vertical pivot 10, and 10 upper end of vertical pivot is connected with brake 7.Driving gear 11
Between two traveling wheels 5.
Horizontal axis 2 is connect with driving motor 3.Driving motor 3 is radial in the present embodiment puts, and it is wider to be suitable for box width
Vehicle, such as Type B vehicle；When box width is inadequate, such as when vehicle is c-type vehicle, then driving motor 3 is placed in the lower section of horizontal axis 2, driven
Dynamic motor 3 passes through a pair of of gear auxiliary driving with horizontal axis 2.
Traveling wheel 5 on horizontal axis 2, passes through first clutch 4 by bearing or bearing shell empty set between traveling wheel 5 and horizontal axis 2
Transmission.The main body of first clutch 4 is mounted on horizontal axis 2.When first clutch 4 is attracted, horizontal axis 2 drives traveling wheel 5 together
Rotation；When first clutch 4 disconnects, the not active rotation of traveling wheel 5.
Second bevel gear 9 by bearing or bearing shell empty set on vertical pivot 10, by the between second bevel gear 9 and vertical pivot 10
The transmission of two clutches 8, the main body of second clutch 8 are mounted on vertical pivot 10.When second clutch 8 is attracted, second bevel gear 9
Vertical pivot 10 is driven to rotate together；When second clutch 8 disconnects, the not active rotation of vertical pivot 10.
First clutch 4 and second clutch 8 are slip clutch in the present embodiment.Optional hydraulic clutch,
Electromagnetic clutch or pneumatic clutch.
The present embodiment discloses a kind of axial anticreep wheel rail system, and other than including above-mentioned rack rails train driving mechanism, it is also
Including two rail 13 and a rack rails 12, rack rails 12 is located on the middle line of the rail plate-girder 14 between two rail 13.
As shown in figure 4, rack rails 12 includes I-steel 122 and two rack gears 121 in the present embodiment；Two rack gears 121 are distinguished
The two sides of 122 web of I-steel are mounted on, I-steel 122 is located on 14 middle line of rail plate-girder between two rail 13.Two rows
It walks wheel 5 to walk respectively on a rail 13 wherein, two driving gears 11 are engaged with a wherein rack gear 121 respectively.Two
Driving gear 11 engages the walking of the rack gear 121 on I-steel 122, and by mechanical-force-transmission structure, climbing capacity has been significantly greatly increased.
The flank of tooth of rack gear 121 can make gear teeth be constrained on the upper of I-steel 122 without departing from the top flange of I-steel 122
Within the scope of the edge of a wing.For example, if the traveling wheel of side has derailing trend, the driving gear 11 of the side can be by work in turning
The top flange of word steel 122 limits, and prevents side driving gear 11 to be detached from rack rails, then prevents train from jumping tooth derailing, guarantee operation
Safety.
The working principle of the invention is introduced below with reference to Fig. 1,2,3:
As shown in Figure 1, train is in no rack rails sections of road.At this point, wheel rail drive mode need to be switched to.First disconnect second clutch
After 8, then close first clutch 4.Driving motor 3 drives horizontal axis 2 to rotate, and the rotation of horizontal axis 2 drives and the affixed brake disc of horizontal axis 2
1, first bevel gear 6, first clutch 4 rotate simultaneously, since first clutch 4 is attracted, so first clutch 4 drives walking
5 rotation of wheel, realizes wheel rail drive.
Since second clutch 8 disconnects, first bevel gear 6 drives second bevel gear 9 to dally, vertical pivot 10 and driving gear 11
It does not rotate.This characteristic makes it when entering slope section, can smoothly enter into rack rails.The structure is suitable for level road section.
Train as shown in Figure 2 is having rack rails sections of road, when selecting wheel rail drive mode, after first disconnecting second clutch 8,
First clutch 4 is closed again.Driving motor 3 drives horizontal axis 2 to rotate, and the rotation of horizontal axis 2 drives and the affixed brake disc 1 of horizontal axis 2, the
One bevel gear 6, first clutch 4 rotate simultaneously, since first clutch 4 is attracted, so first clutch 4 drives traveling wheel 5
Wheel rail drive is realized in rotation；
Since second clutch 8 disconnects, first bevel gear 6 drives second bevel gear 9 to dally, and traveling wheel 5 is driving wheel at this time, drives
Moving gear 11 by rack rails 12 frictional force and be servo-actuated, while drive vertical pivot 10 dally.The mode is suitable for running on flat slope.
As shown in figure 3, train is having rack rails sections of road, when needing to be switched to rack drives mode.First disconnect first from
After clutch 4, then close second clutch 8.Driving motor 3 drives horizontal axis 2 to rotate, and the rotation of horizontal axis 2 drives and the affixed system of horizontal axis 2
Moving plate 1, first bevel gear 6, first clutch 4 rotate simultaneously, and since first clutch 4 disconnects, 5 empty set of traveling wheel is in horizontal axis 2
On not active rotation.
First bevel gear 6 is engaged with second bevel gear 9.First bevel gear 6 drives second bevel gear 9 to rotate, due to second
Clutch 8 is attracted, and second clutch 8 drives vertical pivot 10 to rotate, and the driving gear 11 being fixed on horizontal axis 10 is then driven to rotate.
Driving gear 11 is engaged with rack rails 12, to drive mass motion, driving gear 12 at this time is driving wheel, and traveling wheel 5 is by rail
13 frictional force and be servo-actuated.
Of course, in practical applications, the rack rails train driving mechanism of axial direction anticreep zero defect switching is equipped with control system
System automatically ensures that each pattern switching all first disconnects a clutch, then closes another clutch.
Wheel rail drive and rack drives share a power source in the present invention, after first disconnecting a clutch, then close
Another upper clutch guarantees that only one clutch works at any one time, two clutches is not allowed to work at the same time, it is ensured that
Zero defect switching is carried out between wheel rail drive and rack drives, mode is reliable, runs smooth and safe.
Embodiment two
The difference between this embodiment and the first embodiment lies in: as shown in figure 5, the side of rail 13 is equipped with rack gear in the present embodiment
121, the driving gear 11 of two driving units is engaged with the rack gear 121 on one of rail 13 respectively.
Certainly, the present invention can also have other numerous embodiments, without deviating from the spirit and substance of the present invention,
Those skilled in the art can make various corresponding changes and modifications, but these corresponding changes and change according to the present invention
Shape all should fall within the scope of protection of the appended claims of the present invention.
