Description

Articulated passenger rail vehicle with middle compartment module

Technical field

The present invention relates to a kind of radial type guideway vehicle that is used to transport the passenger that comprises the type in the compartment that supports by forecarriage and trailing truck, particularly a kind of passenger rail vehicle.

Background technology

In traditional passenger train, the compartment is hinged each other in their end.On station track (siding), track switch place and arc track, stand quite significantly side-sway.This side-sway is the compound relative motion between the compartment, comprises transverse translation and rotation.Permission is communicated to next compartment from a compartment flexible railway carriage or compartment (bellows) must hold this relative motion, causes complicated, bulky and heavy structure, and this has limited the space that can be used for the passageway.When train accumulates in the vestibule (vestibule) of end, compartment near station and passenger, laterally quicken obvious especially.It is uncomfortable especially that translational sideways movement between the adjacent compartment makes us feeling, considers from visual angle equally, because it reflects the sensation of unstable and unsafe vehicle body.

What equally, the position of the vestibule at place, end, compartment neither be optimum.When getting on the bus, the space that is used for the passenger in the vestibule is limited.Luggage must pass little car door and transport.Near car door, almost there is not the space to can be used for holding the luggage of maximum package.Because it is narrow to lead to the passageway of dining car, make to have queued team along passage.Yet, owing to when platform is bending, will between car door and platform, be extended with at interval, can have problems thus so on the other hand, if car door is positioned at the middle part in compartment.

In Figure 10, showing in constant radius is the traditional passenger train 200 that moves on the warp rail 202 of R.Compartment 204A, 204B are supported by front and rear four-wheel underframe or bogie truck (bogie) 206A, 208A, 206B, 208 pivotally, and hinged each other by link rod 210 in their end.Usually, the distance between the trailing or leading bogie equals the distance and 2 subduplicate merchant between the jointed shaft in compartment.For the purpose of illustrating, expressed the line of centers 212 of track 202, and the outside intrinsic curve (envelope) 214 of train.Vertically vertical centre plane 215A, the 215B of each compartment main body comprise vertical S. A. 216A, 216B, 218A, the 218B of underframe with respect to the compartment main body, and are intersecting near the position of vertical S. A. and the line of centers 212 of track.

At the station with crooked platform, the edge of platform will be in the outside of intrinsic curve 214, and preferably and it is tangent.Middle part in the compartment, the intrinsic curve on the inboard of compartment and bend is tangent, and the outer lateral in compartment is quite far away to the lateral extent intrinsic curve.Here it is why car door and vestibule can not be positioned at reason away from the middle part, compartment of underframe, wherein car door and vestibule must be opened on both sides so that the platform 222 that can enter recessed platform 220 and protrude.Towards the end in compartment, promptly, equal at two cross sides more or less to the distance of intrinsic curve from the cross side in compartment near the position of underframe.Car door is preferably placed in this zone, because the interval between train 200 and the platform will equate more or less for recessed platform 220 and the platform 222 that protrudes.Yet in this zone, the angle between train and the intrinsic curve is sizable.This means that the interval between train and the platform is not constant, this makes and is difficult to provide folding doorsteps to stride across this at interval.In addition, passenger loading and the easy false judgment of getting off width at interval, and if described interval not by cross-over connection suitably then may damage.

When train process bend, produce another problem.As shown in figure 10, current colector 224 is used for train is connected to catenary.Extend perpendicular to the vertically vertically centre plane in compartment on the top of current colector 224, directly over the S. A. of one of underframe.It is angled and do not have an even centering with respect to the line of centers 212 of track that the current colector top seems.In this structure, be very difficult to accurately control and be applied to preset pressure on the catenary by the current colector top.

On the other hand, if the middle place of current colector between two underframe in compartment, will be on its top, this position perpendicular to line of centers, the distance of decentering line will significantly increase so.

From EP0,121,503 can know a kind of light rail vehicle with two compartments, and wherein two compartments are hinged to the intermediate interconnection passage.Each compartment is supported by the near-end bogie truck of far-end bogie truck and close interconnecting channels.Described interconnecting channels can pivot around jointed shaft with respect to each compartment, and this jointed shaft is the S. A. of the bogie truck of corresponding vicinity with respect to the compartment equally.

From US1,875,214 can know a kind of articulated train, its have be arranged on pivotally two between the bogie truck middle compartment and be installed in end on the bogie truck equally pivotally, thereby each bogie truck has two jointed shafts, one is used for contiguous middle compartment, and one is used for contiguous end.Middle compartment is designed to unique passenger traffic that is used for, and the end is designed to the operator's compartment as the driver, the inlet that is used for the passenger, corridor etc.Because this being configured in has two jointed shafts independently separately on the bogie truck, the end may take place on the track of bending with respect to the sizable relative cross motion of middle compartment.All longitudinal forces must be delivered to next compartment from a compartment by bogie truck, and this is commonly referred to be unsafe in case of collision.

Middle compartment module 14 be formed for climbing up train or the vestibule 56 of getting off and from a passenger carriage to next gangway 58.Passenger carriage itself does not need to comprise entrance door and vestibule, and this can reserve more space and be used for passenger seat 60.Each end at each passenger carriage can be provided with the internal partition with sliding door, so that dining car or objective railway carriage or compartment and adjacent middle compartment module are separated.

Fig. 5 and Fig. 6 have described the floor of middle compartment module, below with more detailed description.Middle moveable platform 70 is laterally between two car door opening 51A, 51B, and two slope 72A, 72B are connected to belly board static base station (sill) 74A, the 74B of each end that is positioned at the middle compartment module.Described base station is concordant with the floor level of adjacent vehicle body.Slope 72A, 72B are hinged to the edge of base station 74A, 74B, and have below the belly board 70 or above the free end that extends.Thereby belly board 70 is directed between low position shown in Figure 5 and high position shown in Figure 6 and vertically moves.The electrical motor (not shown) is connected to the worm gearing (not shown) with mobile belly board 70 and slope 72A, 72B between described low and high position.Interchangeablely be, can use the electrical motor or the mechanical power sources of any other type, for example can use hydraulic actuating cylinder or cylinder.In high position, described platform is concordant with the floor of base station and adjacent compartment with the slope.When train in when motion, platform is in high position.AT STATION, platform is lowered to allow wheelchair and/or hand barrow to climb up train and get off and/or the individual that helps bodily injury gets on the bus.For the inclined degree with the slope remains on reasonable levels, base station should be preferably as much as possible away from belly board, and utilizes whole length of middle compartment module.

With reference to figure 7, wherein show articulated passenger rail vehicle 10 according to a second embodiment of the present invention.Passenger vehicle according to a second embodiment of the present invention is intercity guideway vehicle in this example, and it has with first embodiment similarly constructs: identical Reference numeral is used to refer to same or analogous element.

Vehicle has the module 14 of passenger carriage 12A, 12B and mid-mounting.Each passenger carriage has compartment topside 16A, the 16B that is formed by single skin type agent structure 24A, 24B, described agent structure 24A, 24B extend between two annular brace module 100A, 102A, 100B, 102B, and each agent structure supports by two bogie truck 18A, 20A, 18B, 20B.Bogie truck 18A, 20A, 18B, 20B are preferably bogie unit, and it can rotate around S. A. 28A, 30A, 28B, 30B with respect to corresponding supporting module 100A, 102A, 100B, 102B by known center pin of prior art and/or connecting rod.Annular module 102A, 100B at one end are rigidly connected to adjacent single skin type agent structure 24A, 24B, thereby and are connected to mid-mounting module 14 by being articulated and connected at the other end.Each is articulated and connected and has vertical jointed shaft 32A, 32B, and it is with respect to S. A. 30A, the 30B skew of adjacent bogie truck.Flexible railway carriage or compartment between middle compartment module and annular brace module allows to communicate between the compartment.Preferably, the S. A. that is articulated and connected is positioned at the space that is limited by flexible railway carriage or compartment, and for example between annular brace module and middle compartment module, thereby when the compartment pivoted with respect to intermediate module, sideway movement was minimized.

Described intermediate module is identical with the intermediate module of first embodiment.

The annular brace module makes train have modularization, and can be used for equally single skin type compartment topside is connected to cab module 110.In order to improve the degree of modularity, cab module can be selected in the scope of the interchangeable cab module with difformity and/or different technologies specification.Connection between cab module and the supporting module is preferably rigidity, even the pivotally attached operator's compartment also is possible, as disclosed among the US2001/0052305.Interchangeable is that operator's compartment 110 can be connected to intermediate module 114 to provide another car door and/or room to hold bicycle.Advantageously, this intermediate module also can be used as other buffer zone.

If described passenger carriage will be connected to traditional passenger carriage or traditional locomotive, end module 112 can be rigidly connected to the annular brace module so.The length of end module is approximately half of length of middle compartment module, and made that preferably if two end module 112A, 112B are connected to each other, will cause distance between two supporting modules on the both sides of end module to equal distance between two supporting modules on the both sides of intermediate module 14 so.

Compartment and the geometrical structures of first and second embodiment are described below with reference to Fig. 8 and Fig. 9.In these accompanying drawings, vehicle is presented on the warp rail 150 of constant curvature.For the purpose of illustrating, the line of centers 152 of track 150 and the outside intrinsic curve 154 of train have illustrated.Vertically vertical centre plane 156A, the 156B of each compartment topside comprise vertical S. A. 28A, 30A, 28B, the 30B of underframe with respect to the compartment topside, and are intersecting near the position of vertical S. A. and the line of centers 152 of track.The vertical centre plane 158 of intermediate module comprises vertical jointed shaft 32A and 32B.In Fig. 9, following parameters illustrates:

S is the distance between first S. A. and second S. A.;

Z is the distance between first jointed shaft and second jointed shaft;

D is the distance between second S. A. and first jointed shaft;

R is the radius of curvature of track centerline;

X is the distance between the center of curvature of the longitudinal median plane of middle compartment module and track;

W is the distance between the forward and backward wheel shaft of bogie truck;

E is the distance between the line of centers of first or second S. A. and track;

A is the distance between the line of centers of first jointed shaft and track;

I is the distance between the line of centers of the longitudinal median plane in first compartment and track.

Consider different right-angled triangles, provided geometric relationship by following equation with good similarity:

(I) ${(R-i)}^2+{\left(\frac{S}{2}\right)}^2={(R-e)}^2$

(II) ${(R-i)}^2+{(\frac{S}{2}+D)}^2={(R-e+a)}^2$

(III) ${(R-e+a)}^2={\left(\frac{Z}{2}\right)}^2+X^2$

(IV) ${(R-e)}^2+{\left(\frac{W}{2}\right)}^2=R^2$

In conjunction with above-mentioned equation, thus two variable e of cancellation and i, next:

(V) ${\left(\frac{S}{2}\right)}^2-{(\frac{S}{2}+D)}^2+{\left(\frac{W}{2}\right)}^2=R^2-X^2-{\left(\frac{Z}{2}\right)}^2$

Now, if the line of centers of the vertically vertical centre plane of middle compartment module and track is tangent, so:

(VI)X＝R

Can obtain from (V) with (VI):

(VII) ${\left(\frac{S}{2}\right)}^2-{(\frac{S}{2}+D)}^2+{\left(\frac{W}{2}\right)}^2-{\left(\frac{Z}{2}\right)}^2=0$

And last:

(VIII)W ²+Z ²＝(s+2D)2-S ²＝4D(D+S)

Equation (VIII) is irrelevant with radius R.For the bogie truck with one group of wheel, this equation is still effective, and additional conditions are W=0.

When the jointed shaft of the S. A. of bogie truck and compartment main body satisfied requiring of equation (VIII), the track centerline on the constant track of the longitudinal median plane of middle compartment module and any radius of curvature was tangent, as shown in Figure 9.Point of contact half distance between jointed shaft.Therefore, if the middle compartment module is set up as the vestibule that is used to get on the bus, half distance that the car door opening equally should be between jointed shaft promptly equates to two jointed shafts distances more or less so.Because identical, if the middle compartment module is configured to have current colector, half distance that preferably should be between jointed shaft on the current colector top of extended position so.

Parameter S, D, W and Z can very freely select in equation (VIII) restricted portion.Yet should be noted that D should be strict with 0, and Z should be greater than 2.5 to allow the middle compartment module as vestibule and/or as the bracing or strutting arrangement that is used for current colector in the reality.According to a preferred embodiment, be selected such that apart from S:

(IX)? $S=\frac{S+2D+Z}{2}\sqrt{2}$

This equation is similar to the principle of optimality that is used for conventional train, and its middle distance S equals the length of compartment topside and 2 subduplicate merchant.When satisfying this condition, for vehicle that is equipped with intermediate module and the vehicle that is equipped with two end modules as shown in Figure 8, car construction can be optimized, and does not change the distance between the S. A. of two adjacent bogie trucks of two adjacent compartments.

In the Table I below, distance W is fixed as 2.5 meters arbitrarily, and S+2D+Z changes, and S is determined by equation (IX).
