The stress-bearing capability of high bogie 100 can promote the passenger carrying capacity of rail vehicle.
It in some embodiments, as depicted in figs. 1 and 2, can at the center along its length of the first traveling wheel shaft 301
Pivotly it is connected with one end (for example, front end on the length direction of track) of tie-beam 30, the extension of the second travelling wheel 32
At the center of length direction can with the other end of tie-beam 30 (i.e., it is illustrated that rear end) be pivotly connected.As a result, in bogie
When 100 steering, the first traveling wheel shaft 301 and the second traveling wheel shaft 302 are respectively relative to the pivot of tie-beam 30 so that first level
Wheel 21 and spacing of the third horizontal wheels 23 on the length direction of track 200 and the second horizontal wheels 22 and the 4th horizontal wheels 24 are in-orbit
Spacing on the length direction in road 200 occurs linkage and changes, and the deflection of bogie 100 not only may be implemented, but also can avoid
It interferes, can further increase and improve stability and reliability.
Optionally, as shown in figs 2-4, control device 5 may be mounted on tie-beam 30, compact-sized, and connect
Beam 30 does not usually do significantly yaw motion, so as to improve the stability of control device 5, control device 5 and first is made to adjust
The connection of regulating device 41 and the second regulating device 42 is more reliable and more stable.
In some embodiments of the invention, as Figure 1-Figure 4, first level wheel 21 passes through first level wheel shaft 201
Be pivotably mounted on the first travelling wheel 31 first end (such as, it is illustrated that left end), it is horizontal that the second horizontal wheels 22 pass through second
Wheel shaft 202 be pivotably mounted on the first traveling wheel shaft 301 second end (i.e., it is illustrated that right end), third horizontal wheels 23 pass through
The horizontal wheel shaft of third 203 be pivotably mounted on the second traveling wheel shaft 302 first end (such as, it is illustrated that left end), the 4th water
Flat wheel 24 be pivotably mounted on by the 4th horizontal wheel shaft 204 second traveling wheel shaft 302 second end (i.e., it is illustrated that the right side
End).First level wheel 21 and third horizontal wheels 23 are matched by first level wheel shaft 201 and the horizontal wheel shaft of third 203 respectively as a result,
It closes on the lateral surface of track 200, the second horizontal wheels 22 and the 4th horizontal wheels 24 pass through the second horizontal wheel shaft 202 and the 4th respectively
Horizontal wheel shaft 204 coordinates on the lateral surface of the other side of track 200, is not only convenient for realizing steering, and can play anticreep
Effect can further increase reliability and stability.
Optionally, the first regulating device 41 and the second regulating device 42 can be gas spring, in the first regulating device 41
Pressure in pressure and the second regulating device 42 can be detected and controlled by control device 5.That is, the detection of control device 5 is simultaneously
The pressure for controlling the first regulating device 41, to control first level wheel 21 and third horizontal wheels 23 in the length side of track 200
Upward distance, meanwhile, control device 5 detects and controls the pressure of the second regulating device 42, to the second horizontal wheels 22 of control
At a distance from the 4th horizontal wheels 24 are on the length direction of track 200, turning is realized with auxiliary.Certainly, the first regulating device 41
Other devices with the same or similar functions are can also be with the second regulating device 42.
A predetermined pressure difference can be preset in control device 5, carried with subsequent action to judge whether bogie 100 turns to
For foundation.Control device 5 can detect the pressure of the first regulating device 41 and the second regulating device 42, and obtain according to testing result
The pressure difference for obtaining the first regulating device 41 and the second regulating device 42, compares the size of pressure difference and predetermined pressure difference：
When pressure difference is more than predetermined pressure difference, judge that bogie 100 turns to, control device 5 adjusts 41 He of the first regulating device
The pressure of second regulating device 42, makes pressure difference tend to predetermined pressure difference, to which assisted diversion frame 100 realizes steering.I.e.
Bogie 100 can be formed as pressure difference gauche form bogie 100, control first to fourth horizontal wheels 24 by pressure difference, reach
To the purpose of steering.
For example, in conjunction with shown in Fig. 3 and Fig. 4, when bogie 100 is turned right, track 200 generates the second horizontal wheels 22
One probably to the elastic force of right back, the second horizontal wheels 22 drive the first traveling wheel shaft 301 to occur around the front end of tie-beam 30
Deflection, at this point, first level wheel 21 increases at a distance from third horizontal wheels 23 are on the length direction of track 200, first is adjusted
The pressure of device 41 reduces, and the second horizontal wheels 22 subtract at a distance from the 4th horizontal wheels 24 are on the length direction of track 200
Small, the pressure of the second regulating device 42 increases.
Control device 5 detects the pressure of the pressure and the second regulating device 42 of the first regulating device 41, and is tied according to detection
Fruit obtains the pressure difference of the first regulating device 41 and the second regulating device 42, by the predetermined pressure difference of pressure difference and setting
It is compared.When pressure difference is more than predetermined pressure difference, it is believed that bogie 100 turns to the right, the control of control device 5 second
42 pressure release of regulating device, and the pressurization of the first regulating device 41 is controlled, keep the hardness of two gas springs equal.
Due to the variation of pressure difference, the second traveling wheel shaft 302 can also be deflected around the second end of tie-beam 30, at this point, the
The deflection direction of two traveling wheel shafts 302 is with the deflection direction of the first traveling wheel shaft 301 on the contrary, folder as shown in Figure 4 can be formed
Angle, the first travelling wheel 31 and the second travelling wheel 32 and third travelling wheel 33 and the 4th travelling wheel 34 are with the rotation of the angle center of circle and rail
Mark overlaps, and thus turns to bogie 100, to realize the turning of car body.
Optionally, as shown in figs 2-4, control device 5 passes through the first air hose 411 and 41 phase of the first regulating device
Even, and control device 5 is connected by the second air hose 412 with the second regulating device 42.It is adjusted to first thus, it is possible to realize
Regulating device 41 and the control of the pressure of the second regulating device 42, it is simple in structure, it is easy to adjust timely, and also air hose can turn
It adaptively deforms, is hardly damaged when being turned to frame 100, stability and reliability can be improved.
To sum up, bogie 100 according to the ... of the embodiment of the present invention makes horizontal wheels to can be in the reaction force of track 200
Under deflect, huge reaction force can be avoided, bogie 100 is made to turn as automobile, and in control device 5
To under the control of the first regulating device 41 and the second regulating device 42, first to fourth travelling wheel 34 can be met to turning track weight
The requirement of conjunction to realize minor-circle turn, and can be reduced and be wanted to the intensity of bogie 100 and each horizontal wheels
It asks, while also reducing the risk that each horizontal wheels are blown out, improve stability and safety.
