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 and 2, fig. 1 is a schematic view of a portal bogie for a straddle-type monorail train according to an embodiment of the present invention, and fig. 2 is a schematic view of an assembly of the portal bogie and a vehicle body according to an embodiment of the present invention.
The portal bogie provided by the first embodiment comprises a lower framework 2 which is horizontally arranged and an upper framework 5 which is vertically arranged, wherein the lower framework 2 is used for mounting running wheels 10; the upper frame 5 is of a door-shaped structure and spans the lower frame 2, a vertical stop 8 and a supporting beam 7 are arranged at the top of the upper frame 5, the vertical stop 8 is used for being connected with the top of the vehicle body 17, and springs 6 used for being connected with the side walls of the vehicle body 17 are arranged at two ends of the supporting beam 7.
As shown in fig. 2, by providing the upper frame 5 of the portal structure, the portal bogie mounts the elastic member for connecting the bogie and the car body 17 to the upper portion of the car body 17, so that a certain space can be left in the lower portion of the car body 17, and the floor surface of the car body 17 can be designed to be lower by using the space left in the lower portion, thereby reducing the distance between the floor surface and the track beam 1, and making it more convenient for people to get on and off.
As shown in fig. 1, guide wheels 15 are installed at four corners of the lower frame 2, stabilizing wheels 14 are installed at lower positions of the middle parts of the side beams, and a driving device 11 and a foundation brake device 12 are installed at one side of the running wheel 10. The upper frame 5 comprises two door-shaped rods (not marked in the figure) which are arranged in parallel with each other, the two door-shaped rods are fixedly connected by a plurality of longitudinal rods (not marked in the figure) which are perpendicular to the door-shaped rods, the longitudinal rods are parallel to the side beams of the lower frame 2, the door-shaped rods are connected with the end parts of the two side beams of the lower frame 2, the supporting beams 7 are fixedly connected with the longitudinal rods at the top positions, the springs 6 are obliquely hung at the end parts of the supporting beams 7, and the vertical stop 8 is positioned in the middle of the supporting beams 7.
In a specific practical application, the spring 6 may be a rubber spiral composite spring, and in order to improve the vibration damping performance, a vibration damping pad 3 may be disposed between the door-shaped rod and the side beam.
As shown in fig. 1 and 2, the side damper 4 is mounted in the middle of the side member of the lower frame 2, and one end of the side damper 4 remote from the side member is connected to the side wall of the vehicle body 17. The upper frame 5 is provided on both sides with lateral stops 13 for connection with the side walls of the vehicle body 17, the lateral stops 13 being located in the middle of the longitudinal bars.
Example two
Referring to fig. 1, in the first embodiment, the lower frame 2 is provided with only one axle for mounting the running wheels 10, and the second embodiment differs from the first embodiment only in that in the second embodiment, the lower frame 2 is provided with two axles parallel to each other.
The single-axle bogie has only one axle, so that the single-axle bogie belongs to an unstable structure in a vertical plane, namely, when the single-axle bogie is singly placed on a track beam, the single-axle bogie cannot stably work by virtue of the structure, the single-axle bogie can be required to be a stable structure by virtue of the restraint of the vehicle body after the whole vehicle is assembled, when the traction force or braking force acting on the wheel circumference of a running wheel is generated between wheel tracks, the traction force or the braking force can also generate a turning moment for the bogie, therefore, when the lower frame 2 is only provided with one axle, in order to enable the portal bogie to move relatively smoothly, two traction rods 16 for connecting the vehicle body 17 can be arranged at one end of the lower frame 2, and a balance rod 9 for connecting the vehicle body 17 is arranged at the upper end of the upper frame 5, as shown in fig. 1, the two traction rods 16 are positioned in the same horizontal plane, and symmetrically arranged at two sides of the center line of the lower frame 2, and the balance rod 9 and the center line of the lower frame 2 are positioned in the same vertical plane, so that when the portal bogie is subjected to traction force or braking force, the balancing rod 9 generates a sufficient turning moment for restraining the turning moment for the portal bogie.
To improve safety, a running auxiliary wheel (not shown) may be provided at the other end of the lower frame 2 opposite the traction bar 16, which is typically a solid wheel, for example, a cast aluminum wheel core and a urethane rubber structure may be employed.
The invention also provides a straddle-type monorail train, which comprises the portal-type bogie disclosed by the embodiment. The portal bogie disclosed in the above embodiment has the above technical effects, so that the straddle-type monorail train with the portal bogie also has the above technical effects, and is not described herein again.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
