Wherein the first oil pipe 61 and the second oil pipe 62 are actually what is passed through from the bottom of car body 3, but oil in analysis oil circuit for convenience
Trend, the first oil pipe 61 and the second oil pipe 62 have been drawn in the outside of car body 3.
As shown in Figure 1 and Figure 4, when vehicle drives to the corner of track 5, the first car body 31 is introduced into bend, first
Can be produced relative rotation between the bogie 41 of car body 31 and first, and from terms of the direction overlooked, the first car body 31 can be relative to the
One bogie 41 is deflected counterclockwise.Steering cylinder 1 includes piston rod 101, piston 102, limited block 103 and cylinder body 104,
When first car body 31 is rotated, piston rod 101 in the first steering cylinder 11 and the second steering cylinder 12 all can with piston 102,
Make one end of steering cylinder 1 fuel-displaced, and other end oil-feed.
As shown in Figures 2 and 3, direction letter A signified in Fig. 3 is the direction of vehicle traveling, now, the first car body 31 and the
Two car bodies 32 all enter the corner of track 5, and from terms of the direction overlooked, the first car body 31 can be relative to the first bogie 41
Deflect counterclockwise.Now, because the cylinder body 104 in the first steering cylinder 11 and the second steering cylinder 12 is to be hinged on
The top of one car body 31, and the piston rod 101 in the first steering cylinder 11 and the second steering cylinder 12 is to be hinged on first turn
On fixed block 401 to the lower section of frame 41.Therefore, when the first car body 31 is counterclockwise deflected relative to the first bogie 41,
The piston 102 in the first steering cylinder 11 in first car body 31 can be moved upwards so that be brought out on the first steering cylinder 11
Oil and lower end oil-feed；And the piston 102 in first the second steering cylinder 12 in car body 31 can be moved downward so that second turns to
Upper end oil-feed in oil cylinder 12 and lower end is fuel-displaced.
Now, the upper end of the first steering cylinder 11 and the lower end of the second steering cylinder 12 are oil outlet end, and the first steering oil
The lower end of cylinder 11 is oil inlet end with the upper end of the second steering cylinder 12.In the present embodiment, each steering cylinder 1 and two buffering
Valve block 2 is connected, and two described trimmer valve blocks 2 are connected in the both sides of piston 102, that is to say, that the first steering cylinder 11
Oil outlet end and oil inlet end are respectively connected with a trimmer valve block 2, and the oil outlet end and oil inlet end in the second steering cylinder 12 are also each
Connected with a trimmer valve block 2.Each steering cylinder 1 is connected with two trimmer valve blocks 2, is to allow in steering cylinder 1
Piston 102 when moving, trimmer valve block 2 produces damping to the motion of the piston 102 in steering cylinder 1, makes the motion of piston 102
Speed will not be too fast, and buffering car body 3 is relatively rotated with bogie 4, and play and slow down what car body 3 was rotated relative to bogie 4
The effect of speed.
Oil pipe 6 in first car body 31 not only connects steering cylinder 1 with trimmer valve block 2, also by the first car body 31
Each trimmer valve block 2 is connected.And first the first steering cylinder 11 in car body 31 and the second steering cylinder 12 oil outlet end it is all each
Connected with a trimmer valve block 2, then connected the two trimmer valve blocks 2 with oil pipe 6 so that the first steering cylinder 11 and second turn
Oil discharge passage is formed together to the oil outlet end of oil cylinder 12 and two trimmer valve blocks 2 and oil pipe 6.Similarly, the first steering cylinder 11
Oil inlet end and two trimmer valve blocks 2 and oil pipe 6 with the second steering cylinder 12 can together form oil inlet passage.
Now, shape is understood in an angle between the longitudinal axis of the longitudinal axis of the first car body 31 and the first bogie 41,
As the radian of the bend on track 5 is different, the size of this angle is also different.Here this angle is set to α 1, and by the second car
Angle between the longitudinal axis of the longitudinal axis of body 32 and the second bogie 42 is set to α 2, then in order to avoid car body 3 is being turned
When the speed that deflects too fast, angle it is too big, so that it is guaranteed that vehicle smoothly passes over bend, it is necessary to make the first car body 31 and the second car
The deflection of body 32 it is in opposite direction, and allow α 2=α 1.
The first car body 31 is deflection counterclockwise in the present embodiment, accordingly, it would be desirable to make the second car body 32 along time-base.And
The cylinder body 104 in the 3rd steering cylinder 13 and the 4th steering cylinder 14 in second car body 32 is integrally fixed under the second car body 32
Side, and the piston rod 101 in the 3rd steering cylinder 13 and the 4th steering cylinder 14 is to be hinged on consolidating for the top of the second bogie 42
Determine on block 401.Therefore, the piston 102 in the 3rd steering cylinder 13 is moved upwards, and make the work in the 4th steering cylinder 14
Plug 102 is moved downward, and can make the second car body 32 along time-base.
Therefore, upper end now in the 3rd steering cylinder 13 and the lower end of the 4th steering cylinder 14 are oil outlet end, and the 3rd
The lower end of steering cylinder 13 is oil inlet end with the upper end of the 4th steering cylinder 14.It is identical with the principle in the first car body 31, this reality
In applying example, the oil outlet end of the 3rd steering cylinder 13 and the 4th steering cylinder 14 in the second car body 32 all respectively with a trimmer valve block
2 connections, then are connected the two trimmer valve blocks 2 with oil pipe 6 so that the 3rd steering cylinder 13 and the 4th steering cylinder 14 it is fuel-displaced
End and two trimmer valve blocks 2 and oil pipe 6 form oil discharge passage together.Similarly, the 3rd steering cylinder 13 and the 4th steering cylinder
14 oil inlet end and two trimmer valve blocks 2 and oil pipe 6 can together form oil inlet passage.
In two adjacent compartments, with the first oil pipe 61 by the oil discharge passage in the first car body 31 and the second car body 32
Oil inlet passage connection, formed the first oil circuit；And with the second oil pipe 62 by the oil inlet passage and the second car body in the first car body 31
Oil discharge passage connection in 32, forms the second oil circuit.
The process and principle of whole warping resistance are made into following statement now：First car body 31 enter bend after, due to from
Overlook direction sees that the first car body 31 can produce anticlockwise deflection relative to the first bogie 41.And car body 3 and bogie
4 is all again rigidity part, therefore, the relative rotation of the first car body 31 and bogie 4 can force the work in the first steering cylinder 11
The motion upwards of plug 102, and the piston 102 in the second steering cylinder 12 is moved downward.So that the upper end of the first steering cylinder 11 and
The lower end oil extraction of the second steering cylinder 12, and oil drain quantity is respectively V1a and V2a.Because car body 3 and bogie 4 are all rigidity portions
Part, and the distance at the first steering cylinder 11 and the center of second the 12 to the first bogie of steering cylinder 41 is equal, therefore, first
During the relative rotation of car body 31 and bogie 4, the stroke of the piston rod 101 of the first steering cylinder 11 and the second steering cylinder 12 is
Equal, so, V1a=V2a.
Enter into the first oil pipe 61 after first steering cylinder 11 and the oily buffered valve block 2 of the discharge of the second steering cylinder 12
The oil inlet passage of the second car body 32.That is, the first steering cylinder 11 and the oil of the discharge of the second steering cylinder 12 can be entered into
In the oil inlet end of the 3rd steering cylinder 13 and the 4th steering cylinder 14.And the 3rd steering cylinder 13 and the 4th steering cylinder 14 enter
Oil mass is respectively V3b and V4b, likewise, because car body 3 and bogie 4 are all rigidity parts, and the 3rd steering cylinder 13 and
The distance at the center of four the 14 to the second bogie of steering cylinder 42 is equal, therefore, V3b=V4b.
After 3rd steering cylinder 13 and the oil-feed of the 4th steering cylinder 14, piston 102 can be promoted, make the He of the 3rd steering cylinder 13
The oil extraction end of the 4th steering cylinder 14 carries out oil extraction, and the oil drain quantity at the oil extraction end is respectively V3a and V4a.And the 3rd turns to
The oil of the discharge of the steering cylinder 14 of oil cylinder 13 and the 4th can enter the oil inlet passage of the first car body 31 through the second oil pipe 62.Namely
Say, the oil of the 3rd steering cylinder 13 and the discharge of the 4th steering cylinder 14 can enter into the first steering cylinder 11 and the second steering cylinder
In 12 oil inlet end.And the oil inlet quantity of the first steering cylinder 11 and the second steering cylinder 12 is respectively V1b and V2b.
The oil outlet end of each steering cylinder 1 is connected with a trimmer valve block 2, and oil inlet end and another trimmer valve block
2 connections.When being produced relative rotation due to car body 3 and bogie 4, the piston rod 101 in steering cylinder 1 can promote piston 102, make
Its motion, makes one end of steering cylinder 1 fuel-displaced, and other end oil-feed.And trimmer valve block 2 can always be produced when piston 102 is moved
Raw damping, hinders the motion of piston 102, so as to hinder, buffer car body 3 with the relative rotation of bogie 4.
In sum, when vehicle is travelled on rectilinear orbit 5 in Fig. 2, the phase of car body 3 and bogie 4 in same compartment
Diagonal position is zero-bit, that is, longitudinal axis and the bogie 4 of car body 3 longitudinal axes coincident.Now the first car body 31 with
Angle α 1=0, the angle α 2=0 between the second car body 32 and the second bogie 42 between first bogie 41, i.e.,：α1=α2=0.
When the injection 5 of only the first car body 31 bend or the first car body 31 and all injections 5 of the second car body 32 it is curved
In road, now there is relationship below between the first car body 31 and the second car body 32：α1=α2>0, and in the first oil circuit：V1a+V2a=
V3b+V4b=constants, and in the second oil circuit：V3a+V4a=V1b+V2b=constants.
That is, vehicle is when turning, in four steering cylinders 1 in two adjacent compartments, in the first oil circuit
Oil pump capacity and oil inlet quantity be identical, be also identical in the oil pump capacity and oil inlet quantity of the second oil circuit.This can cause the second car
The deflection angle α 2 of the longitudinal axis of the longitudinal axis of body 32 and the second bogie 42, with the longitudinal axis of the first car body 31 and
The deflection angle α 1 of the longitudinal axis of one bogie 41 is equal.
It will be apparent that on the premise of principle of the present invention is not departed from, some improvement or modification made are regarded as this
The protection domain of invention.
