Description
Technical field
The present invention relates to railway bogie, especially but not exclusively relate to self steering bogie for locomotive.
Background technology
Generally accepted idea be safeguard the wheel on the bogie truck direct cost can bogie truck safeguard total cost 25% to 40% between.Whole world cost plenty of time and make great efforts the following this bogie truck of exploitation: it has between low orbit power and wheel and the track low incidence and thereby has less track and wheel weares and teares.On locomotive, lorry and passenger vehicle, the wheel abrasion loss can reach 40% of every vehicle life cycle cost separately, and is if consider the total operating cost of the energy, basic design, equipment utilization and fund cost, then huger.
Self steering bogie is known in the art.This technology of simple form has been used on shipping and the passenger car bogie a lot of years, and be that Scheffel, name are called description in the U.S. Patent number 4067261 of " suspension of damping rolling stock " the invention people, its content is all incorporated at this by the mode of reference.Be usually directed to connect with lever, bar or connecting rod diagonal angle so-called " intersection anchoring " member of the relative axle box on the forward and backward wheel set from guiding.Several other patents, the US Patent numbering 4067261,4067062,4735149,5588367, PCT/IB99/01890, PCT/IB/99/01383 and the WO00/07864 that for example belong to Scheffel, and US Patent numbering 6871598 mechanism and the systems of having described in the bogie truck (bogie truck) that belong to Schaller etc., to realize good bending and stability.
Wheel set with conical or wounded in the battle line contact surface allows some deflections (yaw) degree of freedom, and the difference of the rolling diameter of the inside and outside wheel by axletree, described wheel set can autoregistrations radially on warp rail, move around curve with the guiding rolling stock.This is called " from flange (off-flange) " bending in the art, because the wheel pair is free with the track autoregistration and utilize the tapering of wounded in the battle line contact surface basically, does not therefore need the wheel flange to contact with track during bending.Thereby it is desirable to end wise for the wheel pair and be limited in the horizontal surface, allow to a certain degree the secondary deflection of relative wheel with can be from guiding simultaneously.The axle box of this axle journal by will holding the wheel pair is hanging to bogie frame by elastic restraint device or so-called " cutout (shearing blocks) " and realizes.Cutout allows the wheel parafacies for framework movement of limited extent in all directions in horizontal surface.Further it is desirable to guideway vehicle (lorry, passenger vehicle or locomotive) and can allow operating speed to handle rectilinear orbit with the maximum that has the track condition under the smooth operation pattern now, handle warp rail with minimum lateral creep power.Because the warp rail amount on average accounts for 40% of total stroke length, need be for the good tracking of warp rail.Good tracking causes reducing loss and the wearing and tearing of total railway system, aerial wire, permanent way and rolling stock.Good tracking maximization bending and the adhesive ability utilization of rectilinear orbit.
Provide the clear superiority that is better than conventional bogie from the crooked bogie truck of flange, it is conducive to the wheel pair against low rigidity value deflection, the relative cross motion or so-called " between centers shear rigidity " and parallel wheel deflection or " parallelogram motion " that suppress the wheel pair, cause " driftage (hunting) " of wheel pair to reduce, reduce rail force, and thereby the service life that causes higher maximum speed and increase the wheel pair.
Although the anchoring structure that intersects is suitable for being used on the bogie truck of lorry or trailer-type passenger vehicle, motor-driven passenger vehicle, and engine truck often has by electric traction motor or the indivedual wheel driven pairs of meticulous brake system.These traction motors or brake system occupy the exceptional space between the wheel pair on the bogie truck, make the intersecting member effort is installed.Put as Must Significant Bit with the same horizontal surface of axle box in install that to intersect anchorage element difficult especially.Bogie truck with three axletrees runs into same problem.
Above problem solves in several ways.A kind of method is open in inventing the US Patent 5588367 that the people is Scheffel, is called the framework installing type usually and shears enhancing muscle (FMSS) in industry, and it discloses lever and the connecting rod of the wheel pair outside the space that connects between the wheel.This allows the space between the wheel pair to be used to traction and/or spragging gear.The shortcoming of this method is that its enforcement is to connect the lever of wheel pair and the labyrinth of connecting rod.

The specific embodiment
With reference to the accompanying drawings, wherein same characteristic features is represented by same reference numerals, and the railway bogie that leads certainly is generally by Reference numeral 1 expression.
Have the front truck wheel set from guiding railway bogie 1, it is right operating side 3R that this front truck wheel set has secondary 3, one of the ends of two wheels, and another is left operating side 3L.Bogie truck 1 also has rear wheel pair 4, and it is right operating side 5R that this rear wheel pair has secondary 5, one of the ends of two wheels, and another is left operating side 5L.Comprise the motion of the secondary ends of framework 6 limiting wheels (3 and 5) of the axle box that is installed on the elastic restraint device that is the cutout form, especially, framework and cutout allow the secondary limited motion of end (3 and 5) in generally horizontal plane of wheel, limit its vertical motion simultaneously.
A plurality of fluid cylinder 7 are connected between the secondary end (3 and 5) of wheel and the framework 6.The cylinder that is connected to the front truck wheel set represented by 7L, and 7LL represents to be connected to the cylinder of the secondary end of wheel of left fore side, and 7LR represents to be connected to the cylinder of right fore side.Similarly, the cylinder that is connected to the rear wheel pair is represented by 7T, 7TL and 7TR respectively.Cylinder 7 is double-acting cylinders, operation chamber and back operation chamber before each cylinder has.Hereinafter, purpose for ease of reference, for example, the preceding operation chamber of cylinder will be represented by suffix " F ", the back operation chamber of cylinder will be represented by suffix " R ", the preceding operation chamber of cylinder of the secondary end of wheel that is connected to the left fore side of front truck wheel set 2 is represented that by 7LLF the back operation chamber of same cylinder is represented by 7LLR.
Cylinder connects by the fluid flow arrangements of hydraulic power line 8 forms.Fluid flow arrangements is disposed between the cylinder, particularly between the corresponding chambers of cylinder, only to allow relative to each other other relative motion of deflection on the contrary and limiting wheel pair (2 and 4) of wheel pair (2 and 4).
In first structure of fluid flow arrangements 8, the preceding operation chamber that is connected to the cylinder of front truck wheel set hydraulically connects by the hydraulic power line 8.1 between chamber 7LLF and the chamber 7LLR.Because hydraulic power line 8 provides the hydraulic pressure between two chambers (7LLF and 7LRF) to connect, and will always have the hydraulic fluid of fixed Combination amount in two chambers (7LLF and 7LRF).In other words, if the volume reducing of chamber 7LRF, the volume of chamber 7LLF will increase same amount.Similarly, the preceding operation chamber that is connected to the cylinder of rear wheel pair hydraulically connects by the hydraulic power line 8.2 between chamber 7TLF and the 7TRF.The back operation chamber of the cylinder in the left side of the secondary end of each wheel hydraulically connects by the hydraulic power line 8.3 between chamber 7LLR and the 7TLR, and the back operation chamber of the cylinder on the right side of the secondary end of each wheel hydraulically connects by the hydraulic power line 8.4 between chamber 7LRR and the 7TRR.
In use, first structure of above-mentioned fluid flow arrangements only allows the wheel parafacies for reciprocally deflection.For example (with reference to figure 1), when bogie truck is on crooked left track, as the result of power between wheel and the track, front truck wheel set 2 will be tilted with conter clockwise deflection.When the deflection of front vehicle wheel pair conter clockwise, the volume of chamber 7LLF will trend towards increasing, and the volume of chamber 7LRF will trend towards reducing.This volume changes by hydraulic power line 8.1 realizes that fluid is transferred to chamber 7LLF from chamber 7LRF.The change of the volume of the 7LLR that the result forms is by fluid is realized from the hydraulic power line 8.3 that chamber 7LLR transfers to 7TLR.Equally, the change of the volume of the chamber 7TLF of result's formation is by fluid is realized from the hydraulic power line 8.2 that chamber 7TLF transfers to chamber 7TRF.At last, the change of the volume of the chamber 7TRR of result's formation is by fluid is realized from the hydraulic power line 8.4 that chamber 7TRR transfers to chamber 7LRR.Chamber and fluid flow arrangements form bounded system, and wherein all chambers have identical original volume, and volume changes and be delivered to all chambers via hydraulic power line 8, so that the wheel parafacies is for reciprocally deflection.Thereby, in present example, the volume of chamber 7LRF, 7LLR, 7TLF and 7TRR equates and is littler than the volume of chamber 7LRR, 7LLF, 7TLR and 7TRF, and the volume of chamber 7LRR, 7LLF, 7TLR and 7TRF also must equate and the conter clockwise amount of deflection of front truck wheel set equals the cw amount of deflection of rear wheel pair.
Should be appreciated that in above-mentioned example, fluid flow arrangements need not arrange as described in example definitely, wherein all will realize required result along any structure that the relative cylinder of diagonal line corresponds to each other and fluid flow arrangements forms the fluid flow arrangements of bounded system.For example (as shown in Figure 2), its middle chamber 7LRF hydraulically is connected with 7LLF, and chamber 7TRR hydraulically is connected with 7TLR, and chamber 7LRR hydraulically is connected to chamber 7TLF, and chamber 7LLR hydraulically is connected to chamber 7TRF.The deflection of wheel pair will instead be showed by the front and back wheel parafacies.
The phase counter deflexion that relates to as the forward and backward wheel pair of the most important element that leads is certainly more than described.Except allowing the phase counter deflexion, other relative motion that fluid flow arrangements also must the limiting wheel pair particularly keeps the longitudinal stability of wheel pair during traction or braking, also will prevent the parallel deflection (so-called " parallelogram motion ") of wheel pair.Identical with the conventional cross anchor structure, because this fluid flow arrangements forms the bounded system of any motion of the non-phase counter deflexion of locking, so two kinds of structures of this of this fluid flow arrangements can both limit this undesirable motion.In the structure shown in Figure 3, wherein fluid cylinder is installed diagonally, makes the hypothetical axis that passes along the relative cylinder of diagonal line intersect at the center of bogie truck, and the wheel pair also is limited, cross motion relative to each other, this increases alleged " between centers shear rigidity " in this area.Wherein any structure installed at an angle with respect to the longitudinal centerline of bogie truck of cylinder all will provide resistance to a certain degree or the between centers shear rigidity is provided the wheel pair cross motion in opposite direction that connects.If cylinder is vertically installed, wherein the angle between longitudinal center's axis of cylinder and bogie truck approaches zero, other subsystem is structure example such as Bessel (bissels) between horizontal cross suspension stiffness, horizontal axle box retainer or vertical wheel pair for example, can provide enough between centers shear rigidities for certain operations situation such as low-speed handing.
Outside deflection energy disperser can be connected to the secondary end of wheel so that the buffering of cylinder to be provided.Hydraulic power line 8 also can be designed to have flowing so that the size of buffering to be provided in the restriction conduit.The demand of buffering is relevant with the between centers shear rigidity, and high between centers shear rigidity can reduce the demand to buffering.
Structure operation efficient height among Fig. 3, but make imaginary diagonal line have problem aspect intersecting at the center of bogie truck at the described cylinder in location usually.The structure of Fig. 1 and 2 that the cylinder of vertical installation is shown does not provide the between centers shear rigidity via hydraulic connecting device for bogie truck.If necessary, the between centers shear rigidity will need to provide by other device discussed above.Having under the situation of longitudinal cylinder, what the between centers shear rigidity between the axletree that hydraulic efficiency pressure system causes will be with the bogie truck with firm axle box connecting rod is identical.
The structure of above-mentioned cylinder and fluid flow arrangements allows to abandon the mechanical element of some conventional bogie, such as crank and the lever of the secondary designating system of wheel.Another advantage that this structure is better than traditional mechanical part is " to have more rigidity " between the wheel pair and connect and reduced the lost motion that is caused by play intrinsic in the mechanical system, wearing and tearing and elasticity.The space that this structure needs is less and being connected of big distance between the wheel pair of crossing connection (for example wherein intersecting the three axletree bogie trucks that the mechanical anchor of extension has difficulties with the center axletree) be provided.
Further feature of the present invention allows cylinder and fluid flow arrangements to be set on the existing bogie truck by repacking.Provide cylinder discussed above and fluid flow arrangements this bogie truck can be converted to from flange (off-flange) curved design with cost effective manner to (on-flange) curved design bogie truck on the conventional flange.This can be by realizing with the current existing rigid axle case connecting rod of the hydraulic cylinder changing of correspondingly-sized.This is shown in Fig. 4 to 11.
Fig. 4-Fig. 7 illustrates current existing three axletree bogie trucks, and particularly, it is the type with three power axletrees (powered axles) by the classification Co ' of International Union of Railways (UIC) appointment, and each axletree is driven respectively by traction motor.In the bogie truck of these types, relative to each other counter deflexion is difficult especially mutually with rear wheel pair 4 to make front truck wheel set 2 by the conventional cross anchorage element, therefore needs in fact framework 6 redesigns.Use the fluid flow arrangements of describing in the size fluid cylinder 7 corresponding with the existing axle box connecting rod size on these bogie trucks and the above structure, the fluid flow arrangements shown in Fig. 3 particularly, wherein cylinder is installed by the diagonal angle, and axle box is provided to the deflection degree of freedom and necessary restriction is led certainly with permission.
Fig. 8-Figure 11 illustrates two axletree bogie trucks by UIC classification Bo ' appointment.The cylinder that accompanying drawing illustrates with the cylinder of correspondingly-sized and vertically installation substitutes the axle box connecting rod.Cylinder is hydraulically connected to allow the phase counter deflexion of forward and backward wheel pair according to said structure.Cylinder with Fig. 1,2 in the similar mode of structure install along the longitudinal direction, provide the between centers shear rigidity by the horizontal stop configurations of existing axle box.
In further structure, can make to turn to normal traction and separate with braking force.The yaw motion of wheel pair can be by longitudinal traction and braking force are provided from equalizing bar or the bellcrank/crossbar structure that the wheel pair is delivered to framework.Parting liquid pressing system among the available Fig. 3 of steering effort (guarantee the phase counter deflexion, prevent equal deflection, the power of between centers shear rigidity is provided) provides.
It is contemplated that the present invention will provide the self steering bogie of the minimizing difficult design that the current motor-driven three axletree bogie trucks that account for main flow design.Further imagination the present invention will provide economic replacement scheme at the self steering bogie of current complexity, and compare the efficient that raising is provided with mechanical system.Refiting scheme of the present invention will also allow to implement these systems in existing bogie truck.
The invention is not restricted to fine detail described herein.For example, replace using hydraulic power line, can use conduit under fluid pressure or any other hydraulic connecting device.In addition, the secondary end of wheel need not be connected to framework by cutout, can use any suitable elastic restraint device.
