Description

Technical Field

[0001] The invention belongs to the technical field of maglev train suspension frames, and in particular relates to a traction system for a maglev suspension frame. Background Art

[0002] The driving force of the maglev train is provided by the action of the primary (short stator) of the linear motor installed on the suspension frame module and the aluminum plate on the track. The short stator generates an excitation magnetic field, and the aluminum plate generates an induction magnetic field. The two work together to form traction or braking force to drive the train forward or backward. Each suspension frame has a longitudinal beam and a traction device to provide traction for the connected car body.

DETAILED DESCRIPTION

[0036] The present invention is further described in detail below in conjunction with test examples and specific implementation methods. However, this should not be understood as the scope of the above subject matter of the present invention being limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0037] In view of the fact that different positions of the suspension frame of a maglev vehicle have different requirements for the traction characteristics, decoupling requirements, and stopping effects of the traction system, which causes certain troubles in the structural design of the traction system between the suspension frame and the vehicle body, this embodiment provides a traction system for a maglev suspension frame, which can meet the different requirements of the maglev suspension frame for the traction device, better meet the curve passability, and better provide a lateral stopping effect.

[0038] The magnetic suspension frame in this embodiment has different structural differences at different locations. Specifically, Figure 1 As shown, the magnetic levitation suspension frame in this embodiment includes two parallel suspension frame cross beams 2, and a suspension frame longitudinal beam group is provided in the middle of the magnetic levitation suspension frame, and the suspension frame longitudinal beam group is arranged perpendicular to the direction of the suspension frame cross beam 2.

[0039] exist Figure 1 In the view shown, four suspension frame longitudinal beam groups are arranged in the middle of the magnetic suspension frame in this embodiment. In this embodiment, each suspension frame longitudinal beam group is used as an installation position of a traction device; and in this embodiment, the positions at both ends of the magnetic suspension frame are also used as installation positions of a traction device. That is, Figure 1 In the magnetic suspension frame shown in the figure, six installation positions of the traction device are provided in this embodiment. Figure 1 In the view shown, in this embodiment, the installation positions of the six traction devices are named No. 1, No. 2, No. 3, No. 4, No. 5 and No. 6 from left to right.

[0040] like Figures 1 to 6 As shown, the traction system for the magnetic suspension frame proposed in this embodiment includes a magnetic suspension frame, a vertical Z-shaped traction device, a center pin traction device and a diagonal support traction device. The magnetic suspension frame is located above the rail surface 30.

[0041] With respect to the magnetic levitation suspension frame structure, in this embodiment, vertical Z-shaped traction devices are arranged in some suspension frame longitudinal beam groups in the middle of the magnetic levitation suspension frame, center pin-type traction devices are arranged in other suspension frame longitudinal beam groups in the middle of the magnetic levitation suspension frame, and diagonal bracing-type traction devices are arranged at both ends of the magnetic levitation suspension frame.

[0042] Specifically, in this embodiment, diagonal support traction devices can be set at positions 1 and 6, center pin traction devices can be set at positions 2 and 5, and the vertical Z-shaped traction devices can be set at positions 3 and 4.

[0043] like Figure 2 As shown, the vertical Z-shaped traction device in this embodiment includes a rotating arm 21, a vehicle body traction arm 18 and two first traction rods 22.

[0044] In the vertical Z-shaped traction device, one end of one of the first traction rods 22 is hinged on one of the suspension frame cross beams 2, and the other end of the first traction rod 22 is hinged to one end of the rotating arm 21; one end of the other first traction rod 22 is hinged to the other end of the rotating arm 21, and a rotating shaft 24 is provided in the middle of the rotating arm 21. The rotating arm 21 is hinged to the lower end of the vehicle body traction arm 18 through the rotating shaft 24, and the other end of the first traction rod 22 is hinged to another suspension frame cross beam 2, as shown in the specific Figure 2 shown.

[0045] In the vertical Z-shaped traction device, the upper end of the vehicle body traction arm 18 is used to be fixedly connected to the vehicle body, and the lower end is hinged to the rotating arm 21 through the rotating shaft 24. Preferably, the vehicle body traction arm 18 can be hinged to the middle part of the rotating arm 21. In this embodiment, the axial direction of the rotating shaft 24 is horizontally arranged, and the two first traction rods 22 and the rotating arm 21 form a Z-shaped structure in the same vertical plane.

[0046] Preferably, Figure 2 As shown, the two first traction rods 22 are connected to the suspension frame cross beam 2 through the first mounting seat 23; wherein the first mounting seat 23 is used to be fixedly connected to the suspension frame cross beam 2, and the end of the first traction rod 22 is hinged in the corresponding first mounting seat 23. That is to say, this embodiment includes two first mounting seats 23, and each first traction rod 22 in this embodiment is connected to the corresponding suspension frame cross beam 2 through one first mounting seat 23.

[0047] In this embodiment, the end of one of the first traction rods 22 is hinged to the upper portion of the inner side of one of the suspension frame cross beams 2 , and the end of the other first traction rod 22 is hinged to the lower portion of the inner side of the other suspension frame cross beam 2 .

[0048] In this embodiment, a first traction rod 22 is hinged at each end of the rotating arm 21, and the two first traction rods 22 are hinged on two suspension frame beams 2 in the middle of the magnetic suspension frame, so as to achieve traction between the vehicle body and the magnetic suspension frame.

[0049] In addition, the rotating shaft 24 in the vertical Z-shaped traction device is axially arranged horizontally, and the two first traction rods 22 and the rotating arm 21 form a Z-shaped structure in the same vertical plane. That is, when in use, the Z-shaped structure in the vertical Z-shaped traction device is installed vertically, so that the decoupling performance of the Z-shaped structure is transferred from the vertical direction to the horizontal direction, so as to meet the larger horizontal displacement requirements between the magnetic suspension frame and the vehicle body, and improve the curve passability of the vehicle body.

[0050] like Figure 3As shown, in this embodiment, diagonal bracing traction devices are respectively provided at both ends of the magnetic levitation suspension frame, so that the embodiment can reduce the longitudinal impact to a certain extent while transmitting the traction braking force. The diagonal bracing traction device in this embodiment includes a second traction rod 20, a fixed connection seat 19 and a movable connection seat 16, one end of the second traction rod 20 is hinged to the fixed connection seat 19, and the other end is hinged to the movable connection seat 16, and the fixed connection seat 19 is fixed on the vehicle body, and the movable connection seat 16 is installed on one of the suspension frame cross beams 2 through a compression spring 17. It should be noted that the second traction rod 20 should be arranged at an angle.

[0051] like Figures 4 to 6 As shown, in this embodiment, a center pin type traction device is arranged in the suspension frame longitudinal beam group in the middle of the magnetic suspension frame. Specifically, in this embodiment, the center pin type traction device is arranged at both the No. 2 position and the No. 5 position, and the center pin type traction device of this embodiment includes a tapered center pin 4, a traction seat 5, a first traction arm and a second traction arm.

[0052] In the center pin type traction device, the conical center pin 4 is preferably a hollow structure, and the top of the conical center pin 4 is connected to the vehicle body. Specifically, the top of the conical center pin 4 is the large end of the conical center pin 4, and the lower part of the conical center pin 4 is the small end of the conical center pin 4. Figure 4 As shown, a through hole is provided at the axial position of the upper part of the tapered center pin 4. To facilitate the connection between the tapered center pin 4 and the vehicle body, the top of the tapered center pin 4 is a plane, and the top of the tapered center pin 4 is connected to the vehicle body through a plurality of fastening bolts. The rail surface 30 is located below the suspension frame cross beam 2 and the tapered center pin 4, the upper surface and the lower surface of the suspension frame cross beam 2 are parallel to the rail surface 30, and the axis of the tapered center pin 4 is perpendicular to the rail surface 30.

[0053] like Figure 5 , Figure 6 As shown, in the center pin type traction device, the middle part of the outer periphery of the tapered center pin 4 passes through the transverse stop seat 3. Therefore, when in use, the middle cone of the tapered center pin 4 can act as a transverse stop, and then when the transverse displacement between the tapered center pin 4 and the suspension frame longitudinal beam 1 is too large, the middle part of the outer periphery of the tapered center pin 4 can contact the transverse stop seat 3 provided on the suspension frame longitudinal beam 1, so as to limit the problem of excessive relative transverse displacement between the vehicle body and the suspension frame. Figure 6 In the embodiment, a circular hole is provided in the middle of the transverse stop seat 3, and a conical center pin 4 is inserted into the circular hole from top to bottom.

[0054] In this embodiment, the specific structure of the transverse stopper 3 is not limited, as long as it can cooperate with the middle part of the outer periphery of the conical center pin 4 to limit the relative lateral displacement between the vehicle body and the suspension frame. Specifically, the transverse stopper 3 can select a transverse stopper structure commonly used in suspension frames on the market.

[0055] like Figure 5 As shown, the lower portion of the conical center pin 4 extends into the fifth wheel 5, and the lower portion of the conical center pin 4 is fixedly connected to the bottom cover 10 of the fifth wheel 5.

In addition, a buffer member 12 is arranged between the shock absorbing member 11 and the conical center pin 4, so that the conical center pin 4 can have a slight side rolling and nodding movement.

[0057] Preferably, the shock absorber 11 can be selected as a spring, and one end of the spring abuts against the side wall of the tapered center pin 4, and the other end abuts against the bottom cover 10. In order to facilitate the vibration reduction of the tapered center pin 4 in the vertical direction, the number of springs can be selected to be multiple, and all springs are arranged at intervals along the circumference of the tapered center pin 4. Of course, in order to facilitate the vibration reduction of the tapered center pin 4 in the vertical direction, the spring can also be sleeved on the tapered center pin 4, and the buffer 12 is filled inside the spring, so that the tapered center pin 4 can be vibration-reduced in the vertical direction, and the tapered center pin 4 can also have a slight side rolling and nodding movement. Specifically, the buffer 12 can be made of rubber material.

[0058] That is, the number of the springs can be one or more. When the number of springs is set to multiple, the multiple springs are arranged at intervals along the circumference of the conical center pin 4, and the buffer 12 is filled in the area between the spring and the outer wall of the conical center pin 4; when the number of the springs is set to one, one spring is sleeved on the conical center pin 4, and the buffer 12 is filled in the spring.

[0059] In the center pin type traction device, the first traction arm includes a first rotating arm 6 and a first pulling rod 8, and the second traction arm includes a second rotating arm 7 and a second pulling rod 9. Figure 5 As shown, in this embodiment, one end of the first rotating arm 6 is fixed to the outer side of the traction seat 5, the other end of the first rotating arm 6 is hinged to one end of the first pull rod 8, and the other end of the first pull rod 8 is hinged to one of the suspension frame beams 2; one end of the second rotating arm 7 is fixed to the outer side of the traction seat 5, the other end of the second rotating arm 7 is hinged to one end of the second pull rod 9, and the other end of the second pull rod 9 is hinged to another suspension frame beam 2; that is, the first pull rod 8 is connected to the traction seat 5 through the first rotating arm 6; the second pull rod 9 is connected to the traction seat 5 through the second rotating arm 7.

[0060] Furthermore, in this embodiment, the first rotating arm 6, the second rotating arm 7, the first pull rod 8 and the second pull rod 9 form a Z-shaped or mirrored Z-shaped structure in the same horizontal plane, as shown in FIG. Figure 5shown.

[0061] In order to facilitate the connection between the suspension frame cross beam 2 and the first tie rod 8, and to facilitate the connection between the suspension frame cross beam 2 and the second tie rod 9, as shown in FIG. Figure 5 As shown, in this embodiment, the second mounting seat 13 is provided on both suspension frame beams 2, and the first pull rod 8 is hinged to the second mounting seat 13 provided on one suspension frame beam 2 through the first traction pin 14, and the second pull rod 9 is hinged to the second mounting seat 13 provided on the other suspension frame beam 2 through the second traction pin 15.
