Marked in the figure as:
1. A rail beam; 2. a traction rod; 3. a balance bar; 4. a foundation brake device; 5. a driving device; 6. a running wheel; 7. a frame body; 8. a transverse damper; 9. rubber hourglass springs; 10. a vertical vibration damper; 11. a stabilizing wheel; 12. and a guide wheel.
Detailed Description
For ease of understanding, the present invention is further described below with reference to the accompanying drawings.
Example 1
Referring to fig. 1, a schematic layout diagram of a single-traction-rod bogie of a straddle-type monorail train according to a first embodiment of the present invention includes a frame body 7 in a shape of a Chinese character kou, guide wheel mounting seats (not labeled in the figure) are fixedly connected to four corners of the frame body 7, wheel shafts (not shown in the figure) are positioned in the middle of the frame body 7, the number of the wheel shafts is one, and running wheels 6 are mounted on the wheel shafts.
By designing the framework body 7 into a square shape and installing only one wheel axle in the framework body 7, compared with the traditional double-shaft bogie, the single-traction-rod bogie provided by the invention has the characteristics of light weight and small volume, and is more beneficial to the straddle type monorail train to smoothly pass through the track with a small radius curve.
As shown in fig. 1, the guide wheels 12 are mounted on guide wheel mounting seats at four corners of the frame body 7, the two sides of the frame body 7 extend downwards to form stabilizing wheel mounting seats, the stabilizing wheels 11 are mounted on the stabilizing wheel mounting seats, the guide wheel mounting seats are generally detachably connected with the frame body 7, and the stabilizing wheel mounting seats are generally welded with the frame body 7.
Example two
Referring to fig. 1, in the first embodiment, the number of running wheels 6 is two, and the second embodiment is different from the first embodiment only in that the number of running wheels 6 is different, and in the second embodiment, the number of running wheels 6 is one.
In a specific practical application, the running wheel 6 is generally a nitrogen-filled tubeless rubber tire.
Example III
Referring to fig. 1, in the first embodiment, the axle is in a cantilever structure, and in the third embodiment, the axle is in a simply supported structure, which is different from the first embodiment only in the structural form of the axle.
In the above embodiments, the driving device 5 and the foundation brake device 4 may be provided on one side of the frame body 7, and the rubber hourglass spring 9 may be provided on the other side opposite to the driving device 5 and the foundation brake device 4, as shown in fig. 1.
The rubber hourglass spring 9 can transmit vertical load as well as transverse load, and in order to improve the transverse stability of the single-traction-rod bogie, two transverse shock absorbers 8 can be respectively arranged on two sides of the framework 7, and the two transverse shock absorbers 8 are arranged in the diagonal direction of the framework 7, as shown in fig. 1. In order to improve the vertical stability of the single-traction-rod bogie, one vertical damper 10 may be provided on each side of the frame body 7, and two vertical dampers 10 may be disposed in a diagonal direction of the frame body 7, which is staggered with respect to the two lateral dampers 8.
The single traction rod type bogie provided by the invention has only one wheel axle, so that the single traction rod type bogie belongs to an unstable structure in a vertical plane, namely, when the single traction rod type bogie is singly placed on a track beam, the single traction rod type bogie can not stably work by virtue of the structure, the single traction rod type bogie can be a stable structure only by virtue of the restraint of a vehicle body after the whole vehicle is assembled, and when wheel circumference traction force or braking force acting on a running wheel is generated between wheel tracks, the traction force or the braking force can also generate a turning moment for leading a point head to the framework 7, in order to lead the single traction rod type bogie to stably move forwards, a balance rod 3 and a traction rod 2 for connecting the vehicle body can be arranged at one end of the framework 7, as shown in fig. 1, the balance rod 3 and the traction rod 2 are arranged in parallel and are positioned in the same vertical plane with the center line of the framework 7, the position of the balance rod 3 is higher than the axis of the wheel axle, and the position of the traction rod 2 is lower than the axis of the wheel axle, so that when the single traction rod type bogie is acted on by traction force or braking force, enough acting force is generated in the balance rod 3 to balance (or braking force) to cause the turning moment, and the point head movement of the framework 7 is restrained.
Referring to fig. 1, for safety, a travel auxiliary wheel (not shown) may be provided at the other end of the frame body 7 opposite to the balance bar 3 and the traction bar 2, and the travel auxiliary wheel is generally a solid wheel, for example, a cast aluminum wheel core and a urethane rubber structure may be used.
The invention also provides a straddle-type monorail train, which comprises the single traction rod type bogie disclosed by the embodiment. The single-traction-rod-type bogie disclosed in the above embodiment has the above technical effects, so that the straddle-type monorail train with the single-traction-rod-type bogie also has the above technical effects, and is not described herein again.
