Definitions
- This invention relates to railway bogies, and more particularly, but not exclusively to a self-steering bogie for a locomotive.
- Self steering bogies are known in the art. The technology in its simplest form has been used on freight and coach bogies for many years and is described in United States patent number 4,067,261 in the name of Scheffel entitled “Damping Railway Vehicle Suspension", the contents of which is incorporated herein in its entirety by way of reference. Self-steering usually involves so called “cross-anchor” members which connect diagonally opposing axleboxes on leading and trailing wheelsets with levers, rods or links.
- Wheelsets with conical or profiled treads which are allowed some yaw freedom, can align themselves radially on a curved track through a difference of rolling diameters on the inner and outer wheels of an axle to guide a railway vehicle around a curve.
- This is referred to in the art as "off flange" curving, as the wheelsets are substantially free to align themselves with the track and utilise the conicity of profiled treads and it is not necessary for a wheel flange to contact the track during curving. It is thus desirable for wheelsets to be constrained in the horizontal plane, longitudinally, whilst allowing a degree of relative wheelset yaw to enable self-steering.
- axleboxes which house the journals of the wheelsets
- shear blocks allow a limited degree of movement of the wheelsets relative to the frame within the horizontal plane in all directions.
- a rail vehicle wagon, coach or locomotive
- tangent track at maximum allowable operating speed for the existing track conditions, in a stable running mode and negotiate curved track with the minimum of lateral creep forces. Because curved track amounts, on average, to 40% of a total journey length, good tracking on curved track is necessary. Good tracking leads to reduced wear and tear on all railway systems; overhead conductor, permanent way and rolling stock. Good tracking maximizes adhesion utilization both on curves and tangent track.
- Off-flange curving bogies offer significant advantages over conventional bogies in that it facilitates wheelset yaw against a low stiffness value, constrains relative lateral movement of wheelsets or so called “inter axle shear stiffness” and also parallel wheel yaw or “parallelogramming", which results in decreased “hunting" of the wheelsets, lower track and rail forces and thus a higher maximum speed, and increased service life of wheelsets.
- cross-anchor configuration is suitable for bogies used on freight or trailer coach cars, motorised coach and locomotive bogies often have wheelsets which are individually driven by electric traction motors or elaborate brake systems. These traction motors or brake systems take up additional space on the bogie between wheelsets which makes it laborious to install cross-anchor members. It is especially difficult to install the cross-anchor members in the same horizontal plane as the axle boxes which is the most effective position. A similar problem is encountered with bogies having 3 axles.
- a self-steering railway bogie comprising:
- the hydraulic cylinders are double-acting cylinders having operatively front and rear chambers and a piston between the front and rear chambers.
- the chambers have the same rate of change in volume with piston travel.
- Each chamber has hydraulic connection means for connecting a hydraulic line, such as a pipe or a tube, which forms part of the fluid flow means.
- the fluid flow means allow the cylinders to move such that diagonally opposing cylinders correspond to each other.
- the operatively front chambers of the hydraulic cylinders attached between the frame and the leading wheelset ends are hydraulically connected.
- the operatively front chambers of the hydraulic cylinders attached between the frame and the trailing wheelset ends are hydraulically connected.
- the operatively rear chambers of the cylinders on a side are hydraulically connected, and also the operatively rear chambers of the cylinders on an opposing side are connected.
- the operatively front chambers of the cylinders attached between the leading wheelset ends and the frame are hydraulically connected and the operatively rear chambers of the hydraulic cylinders attached between the rear wheelset ends and the frame are hydraulically connected.
- the rear chamber of the cylinders attached to the leading wheelset on a side is hydraulically connected to the front chamber of the cylinder attached to the trailing wheelset on an opposing side.
- the chambers are cross and diagonally connected.
- a further feature of the invention is that the hydraulic cylinders and fluid flow means can be retrofitted to currently existing bogies.
- the retrofitting may be done by replacing rigid axle box links with hydraulic cylinders of corresponding size.
- the cylinders may be attached longitudinally.
- the cylinders may be attached diagonally.
- the cylinders are mounted diagonally so that imaginary axes through opposing leading and trailing cylinders intersect at the centre of the bogie.
- the diagonally attached cylinders also restrain relative lateral movement of the wheelsets without a disturbing moment on the frame.
- Cylinders can also be mounted at an angle between purely longitudinal and fully diagonal positions.

- Figure 2 is a schematic representation of a second arrangement of hydraulic cylinders and fluid flow means of a self steering railway bogie

- Figure 5 is a perspective view the three axle bogie from below showing the enlarged views of cylinders
- Figure 6 is a top view of a three axle bogie
- Figure 7 is a side view of a three axle bogie with angled cylinders
- Figure 8 is a perspective view of a two axle bogie with longitudinal cylinders from above;
- Figure 9 is a perspective view of the two axle bogie from below showing enlarged views of leading and trailing cylinders;
- Figure 10 is a bottom view of the two axle bogie.
- Figure 11 is a side view of the two axle bogie.
- a self-steering railway bogie is generally indicated by reference numeral 1.
- the self-steering railway bogie 1 has a leading wheelset with two wheelset ends 3, one being an operatively right end 3R and the other being an operatively left end 3L.
- the bogie 1 also has a trailing wheelset 4 with two wheelset ends 5, one being and operatively right end 5R and the other being an operatively left end 5L.
- a number of fluid cylinders 7 are attached between the wheelset ends (3 and 5) and the frame 6.
- the cylinders which are attached to the leading wheelset are indicated by 7L, 7LL indicates the cylinder attached to the wheelset end on the operatively left side and 7LR indicates the cylinder attached to the operatively right side.
- the cylinders attached to the trailing wheelset are indicated by 7T, 7TL and 7TR respectively.
- the cylinders 7 are double acting cylinders, each having an operatively front chamber and an operatively rear chamber.
- the operatively front chamber of the cylinders will be indicated by suffix "F” and the operatively rear chamber of the cylinder will be indicated by suffix "R", for example, the operatively front chamber of the cylinder attached to the wheelset end on the operatively left side of the leading wheelset 2 is indicated by 7LLF and the operatively rear chamber of the same cylinder is indicated by 7LLR.
- the cylinders are connected by fluid flow means in the form of hydraulic tubes 8.
- the fluid flow means is arranged between the cylinders, and particularly between the respective chambers of the cylinders, to allow wheelsets (2 and 4) to yaw only inversely relative to each other and restricting other relative movement of the wheelsets (2 and 4).
- the operatively front chambers of cylinders attached to the leading wheelset are hydraulically connected by a hydraulic tube 8.1 between chamber 7LLF and chamber 7LRF.
- the hydraulic tubes 8 provides the hydraulic connection between the two chambers (7LLF and 7LRF)
- a fixed combined amount of hydraulic fluid will always be present in the two chambers (7LLF and 7LRF).
- the operatively front chambers of the cylinders attached to the trailing wheelset are hydraulically connected by a hydraulic tube 8.2 between chambers 7TLF and 7TRF.
- the operatively rear chambers of the cylinders on the left side of each wheelset end are hydraulically connected by hydraulic tube 8.3 between chamber 7LLR and 7TLR and the operatively rear chambers of the cylinders on the right side each wheelset end are hydraulically connected by hydraulic tube 8.4 between chambers 7LRR and 7TRR.
- the first arrangement of the fluid flow means described above allows the wheelsets to yaw only inversely relative to each other. For example (referring to Figure 1 ), when the bogie is on a track which curves left, the leading wheelset 2 will be inclined to yaw counter clockwise as a result of the forces between the wheels and the track.
- the volume of chamber 7LLF will tend to increase and the volume of chamber 7LRF will tend to decrease.
- the volume changes are enabled by the hydraulic tube 8.1 and fluid is transferred from chamber 7LRF to chamber 7LLF.
- the resulting change in volume of 7LLR is enabled by hydraulic tube 8.3 which transfers fluid from chamber 7LLR to 7TLR.
- the resulting change in volume of chamber 7TLF is enabled by hydraulic tube 8.2 which transfers fluid from chamber 7TLF to chamber 7TRF.
- the resulting change in volume of chamber 7TRR is enabled by hydraulic tube 8.4 which transfers fluid from chamber 7TRR to chamber 7LRR.
- the chambers and fluid flow means forms a closed system wherein all chambers have the same initial volume and volume changes are transferred through the hydraulic tubes 8 to all chambers to reflect wheelset yaw inversely relative to each other.
- the volumes of chambers 7LRF, 7LLR, 7TLF and 7TRR are equal and smaller than the volumes of chambers 7LRR, 7LLF, 7TLR and 7TRF which are necessarily also equal and the amount of counter-clockwise yaw of the leading wheelset is equal to the amount of clockwise yaw of the trailing wheelset.
- the fluid flow means need not be exactly arranged as described in the example and any arrangement of the fluid flow means whereby diagonally opposing cylinders correspond to each other and the fluid flow means forms a closed system will achieve the desired results.
- chambers 7LRF and 7LLF are hydraulically connected
- chambers 7TRR and 7TLR are hydraulically connected
- chamber 7LRR is hydraulically connected to chamber 7TLF
- chamber 7LLR is hydraulically connected to chamber 7TRF.
- Wheelset yaw will be inversely reflected by the leading and trailing wheelsets.
- the fluid flow means In addition to allowing inverse yaw, the fluid flow means must also restrict other relative movements of the wheelsets, particularly to keep wheelsets longitudinally stable during traction, or braking, and also to prevent parallel yaw of the wheelsets (so- called "parallelogramming"). Both arrangements of the fluid flow means restrict such undesirable movements, as the fluid flow means forms a closed system which locks any movement which is not inverse yaw, similar to conventional cross-anchor arrangements.
- cylinders are mounted longitudinally wherein the angle between the cylinders and the longitudinal center line of the bogie approaches zero, other sub-systems, such as the horizontal-lateral suspension stiffness, lateral axle box stops or longitudinal inter-wheel set structures such as bissels, could provide adequate inter-axle shear stiffness for some operating situations such as slow speed operation.
- other sub-systems such as the horizontal-lateral suspension stiffness, lateral axle box stops or longitudinal inter-wheel set structures such as bissels, could provide adequate inter-axle shear stiffness for some operating situations such as slow speed operation.
- External yaw dampers may be attached to the wheelset ends to provide damping of the cylinders.
- the hydraulic tubes 8 may also be dimensioned to restrict flow in the pipes to provide damping. The requirement for damping is related to the inter-axle shear stiffness and higher inter-axle shear stiffness may alleviate the need for damping.
- the arrangement of cylinders and fluid flow means described above allows for some of the mechanical elements of a conventional bogie, such as cranks and levers of the wheel set guidance system, to be disposed of.
- a further advantage of the arrangement over conventional mechanical components is a 'stiffer' connection between the wheel sets and a reduction of lost motion resulting from free-play, wear and elasticity inherent in mechanical systems.
- the arrangement requires less space and provides for connections over larger distances between connected wheel sets, for example a 3-axle bogie in which in which a mechanical anchor extending across the center axle is difficult.
- a further feature of the invention allows cylinders and fluid flow means to be retrofitted to existing bogies.
- Providing a conventional on-flange curving design bogie with the cylinders and fluid flow means discussed above, will convert the bogie to an off-flange curving design in a cost effective manner. This may be done by replacing currently existing rigid axle box links with hydraulic cylinders of corresponding size. This is shown in Figures 4 to 11.
- Figures 4 to 7 show a currently existing three axle bogie, specifically of the type having three powered axles, each individually driven by traction motors, designated by International Union of Railways (UIC) classification Co'.
- UICC International Union of Railways
- the leading wheelset 2 and the trailing wheelset 4 to yaw inversely relative to each other with conventional cross-anchor members and will require a substantial re-design of the frame 6.
- fluid cylinders 7 which correspond in size to existing axle box links on these bogies and fluid flow means as described in the arrangements above, specifically the fluid flow means shown in Figure 3, wherein the cylinders are diagonally mounted, the axle-boxes are provided with yaw freedom and necessary restraint to allow self-steering.
- Figures 8 to 11 show a two axle bogie designated by UIC classification Bo'.
- the drawings show the axle box links replaced with cylinders of corresponding size and longitudinally mounted cylinders.
- the cylinders are hydraulically connected according to the arrangements described above to allow inverse yaw of the leading and trailing wheelsets.
- the cylinders are mounted in a longitudinal direction similar to the arrangements shown in Figures 1 and 2 and inter axle shear stiffness is provided by the existing axle box lateral stop arrangement.
- the yaw motion of the wheel set can be accommodated by a balancing beam or bell crank/cross rod arrangement that will transmit the longitudinal traction and braking forces from wheelset to frame.
- the steering forces forces to ensure opposite sense yaw, prevent same sense yaw, provide inter-axle shear stiffness
- the invention will provide a self steering bogie which alleviates design difficulties currently prevalent in motorised and 3-axle bogie design. It is further envisaged that the invention will provide an economical alternative to current complex self steering bogies and providing increased efficiency compared to mechanical systems. The retrofitting aspect of the invention will also allow implementing these systems in already existing bogies.
