Definitions
- the invention deals with an arrangement of a low-deck tram car for passenger transport, designed particularly for municipal transport.
- Low-deck trams are manufactured with low decks most through the vehicle length, while the height in the range of 350 ⁇ 450 mm over the rail top may be considered standard and the minimum standard passing width is 600 mm.
- bogies of these trams are usually equipped with broken axle beams with independently mounted pairs of wheels with common geometrical axis of rotation. These axle beams with independently mounted wheels substitute the standard wheel sets, i.e. pairs of wheels pressed on common axles, and enable passing the floor at the low-deck level even between wheels.
- the wheels and the bogie bearing structure between the wheels restrict the passenger space when they turn around the vertical axis towards the vehicle body, that the width X of the passenger space is insufficient at the part over the bogie, thus smaller than standard, see Fig. 1 .
- a low-deck vehicle consists of more sections (cars), where a non-rotable bogie is attached under each odd section
- the width Y of the low-deck pass through the vehicle extends to the standard level see ( Fig. 2 ), for instance with driving bogie according to GB 22898877 .
- Fig. 2 the standard level see
- GB 22898877 driving bogie according to GB 22898877 .
- These vehicles have moreover lower number of wheel sets (pairs) than vehicles with high deck level because of lower number of sections and thus also bogies and so the vertical load on one wheel set is higher, which is inconvenient for the operation.
- the passing width for passengers may be enlarged, while the mounting of the vehicle body on bogies remains rotable, by locating the pivoting point of the vehicle body to the vertical centre of the wheel set (pair of opposite wheels).
- Location of vehicle bodies of adjacent sections of a tram on a single bogie this way enables relative enlargement of the passing width for passengers.
- efforts for maintaining low deck level also over the bogies brings space problems, where the bogie cannot be equipped for example by double spring suspension, or these bogies are not equipped with driving mechanisms (patent IT 21163 A/84 ), or may be equipped with driving mechanisms, but then there is not enough space for disc brakes and the bogie only has block brakes (patent IT1216453 ). In a two-car vehicle only the middle bogie may be solved this way.
- the end bogies are rotable with the deck higher by approx. 200 mm.
- the above disadvantages are removed by low-deck articulated rail vehicle according to claim 1.
- the vehicle consists of articles having a body and a chassis, arranged in configuration consisting of at least two cars or extended by at least one middle car that is equipped with one rotatable end bogie arranged under both the front part of the first vehicle body of the car configuration and under the rear parts of the last vehicle body of the car configuration, and by at least one middle bogie for two adjacent vehicle bodies of the car configuration to be rotatably mounted on the middle bogie, while each of the adjacent vehicle bodies is mounted on the middle bogie in it's each separate bearing point, while there are drives and brakes located at the outer sides of wheels with respect to the vehicle longitudinal axis.
- the bogie arrangement allows the elements of primary and secondary springing to be located in the space between the pairs of independently mounted wheels, and the drives and brakes on the outer side of the wheel in relation to the vehicle longitudinal axe. Thanks to this arrangement the deck over the bogies may also be kept in the standard low level, which is only slightly higher than the rest of the passenger space floor, while both the parts of the floor are connected with a barrier free transition part of slightly elevated ramps, while the passing width of the vehicle remains standard.
- connection of the individual sections of the body with the bogies is based on the principle that the pivot points of both of the adjacent bodies of the vehicle on the middle bogie is always geometrically located on the vertical axe going through the centre of rotation of the common rotation axis of one pair of the wheels, and the pivot point of the end bogie is vertically situated on the lengthwise axis of the bogie relatively close (approx.
- Each section of the vehicle body mounted on the middle bogie is mounted by means of a bearing, which may be solved as an axial bearing or a tilting spherical bearing arranged on a cradle, while both the cradles on each middle bogie are connected by a rod transferring longitudinal forces between the sections.
- the rod arrangement and its attachment to the cradles enable the adjacent sections to move mutually along the longitudinal and transversal axes within the directional and vertical guiding of the rails.
- both the cradles may form a single solid unit, as the mutual movements of the sections around the longitudinal and transversal axes will be enabled in the spherical bearings.
- the longitudinal forces from the vehicle body sections to the bogie are transmitted by a rod connecting each of the cradles of the middle bogie with the frame of the middle bogie.
- the body is mounted on the bogie by means of a bearing and a cradle with shifted mounting of the vehicle body against the springing sets and thus against the bogie centre.
- An axial ball bearing is for example used here for attachment of the vehicle body section, as it is capable of transferring the moment caused by eccentric load on the cradle.
- the arrangement of both the bogie types according to the invention will enable a low deck to be kept all through the vehicle length at the standard level, even over the bogies, while the floor is stepless, only with ramps with gradual elevation of maximum 1 : 10, while the passing width of the vehicle over the middle bogies remains at least standard and over the end bogies is 70 % of the standard width, while the vehicle shows very good driving properties thanks to the use of primary and secondary springing, and the vehicle shows very good driving properties and minimum wear of wheels and rails, thank to the rotable mounting of the vehicle body on the bogies, which is unusual for low-deck vehicles, and the wheels of all the bogies may be driven and braked by disc brakes.

Description
- The invention deals with an arrangement of a low-deck tram car for passenger transport, designed particularly for municipal transport.
- Low-deck trams are manufactured with low decks most through the vehicle length, while the height in the range of 350÷450 mm over the rail top may be considered standard and the minimum standard passing width is 600 mm. To keep the deck height at this standard level bogies of these trams are usually equipped with broken axle beams with independently mounted pairs of wheels with common geometrical axis of rotation. These axle beams with independently mounted wheels substitute the standard wheel sets, i.e. pairs of wheels pressed on common axles, and enable passing the floor at the low-deck level even between wheels.
- However where rotable bogies are used, the wheels and the bogie bearing structure between the wheels restrict the passenger space when they turn around the vertical axis towards the vehicle body, that the width X of the passenger space is insufficient at the part over the bogie, thus smaller than standard, see
Fig. 1 . - If a low-deck vehicle consists of more sections (cars), where a non-rotable bogie is attached under each odd section, the width Y of the low-deck pass through the vehicle extends to the standard level see (
Fig. 2 ), for instance with driving bogie according toGB 22898877 - The passing width for passengers may be enlarged, while the mounting of the vehicle body on bogies remains rotable, by locating the pivoting point of the vehicle body to the vertical centre of the wheel set (pair of opposite wheels). Location of vehicle bodies of adjacent sections of a tram on a single bogie this way enables relative enlargement of the passing width for passengers. However efforts for maintaining low deck level also over the bogies brings space problems, where the bogie cannot be equipped for example by double spring suspension, or these bogies are not equipped with driving mechanisms (patent
IT 21163 A/84 IT1216453 - The above disadvantages are removed by low-deck articulated rail vehicle according to
claim 1. The vehicle consists of articles having a body and a chassis, arranged in configuration consisting of at least two cars or extended by at least one middle car that is equipped with one rotatable end bogie arranged under both the front part of the first vehicle body of the car configuration and under the rear parts of the last vehicle body of the car configuration, and by at least one middle bogie for two adjacent vehicle bodies of the car configuration to be rotatably mounted on the middle bogie, while each of the adjacent vehicle bodies is mounted on the middle bogie in it's each separate bearing point, while there are drives and brakes located at the outer sides of wheels with respect to the vehicle longitudinal axis. - The bogie arrangement allows the elements of primary and secondary springing to be located in the space between the pairs of independently mounted wheels, and the drives and brakes on the outer side of the wheel in relation to the vehicle longitudinal axe. Thanks to this arrangement the deck over the bogies may also be kept in the standard low level, which is only slightly higher than the rest of the passenger space floor, while both the parts of the floor are connected with a barrier free transition part of slightly elevated ramps, while the passing width of the vehicle remains standard. Connection of the individual sections of the body with the bogies is based on the principle that the pivot points of both of the adjacent bodies of the vehicle on the middle bogie is always geometrically located on the vertical axe going through the centre of rotation of the common rotation axis of one pair of the wheels, and the pivot point of the end bogie is vertically situated on the lengthwise axis of the bogie relatively close (approx. 1/3 of the bogie wheel base) to the centre of the common rotation axis of the pair of wheels more distant from the vehicle end, which minimizes the relative transversal movement of the appropriate wheels against the vehicle body during rotation around the vertical axis going through the pivot point of the middle bogie, and possibly through the point of attachment of the vehicle body on the appropriate end bogie, which enables just a small restriction of the passing width W of the vehicle then is usual for other vehicles with rotable bogies, i.e. the W dimension remains at the standard width over the middle bogies and is close to the standard width over the end bogies.
- For the end bogies under the front and rear parts of vehicle this advantage only applies to the pairs of wheels closer to the centre of the vehicle, the outer parts show higher range of movement against the vehicle body, however these pairs of wheels do not restrict the passenger space as they move under the driver's cabin at the front and under conveniently arranged seats at the back, for example arranged into an arch over the space where the outer pair of wheels moves (see
Fig. 7 ). The passage width Z to the driver's cabin or to the seats at the back will remain acceptable, adequate to the intensity of passenger move at these areas. - Each section of the vehicle body mounted on the middle bogie is mounted by means of a bearing, which may be solved as an axial bearing or a tilting spherical bearing arranged on a cradle, while both the cradles on each middle bogie are connected by a rod transferring longitudinal forces between the sections. The rod arrangement and its attachment to the cradles enable the adjacent sections to move mutually along the longitudinal and transversal axes within the directional and vertical guiding of the rails. If spherical bearings are used for attachment of the body sections on the cradles, both the cradles may form a single solid unit, as the mutual movements of the sections around the longitudinal and transversal axes will be enabled in the spherical bearings. The longitudinal forces from the vehicle body sections to the bogie are transmitted by a rod connecting each of the cradles of the middle bogie with the frame of the middle bogie.
- At the end bogies the body is mounted on the bogie by means of a bearing and a cradle with shifted mounting of the vehicle body against the springing sets and thus against the bogie centre. An axial ball bearing is for example used here for attachment of the vehicle body section, as it is capable of transferring the moment caused by eccentric load on the cradle.
- The arrangement of both the bogie types according to the invention will enable a low deck to be kept all through the vehicle length at the standard level, even over the bogies, while the floor is stepless, only with ramps with gradual elevation of maximum 1 : 10, while the passing width of the vehicle over the middle bogies remains at least standard and over the end bogies is 70 % of the standard width, while the vehicle shows very good driving properties thanks to the use of primary and secondary springing, and the vehicle shows very good driving properties and minimum wear of wheels and rails, thank to the rotable mounting of the vehicle body on the bogies, which is unusual for low-deck vehicles, and the wheels of all the bogies may be driven and braked by disc brakes.
- The solution of the invention is illustrated in enclosed drawings, where
Fig. 3 shows a two-car three-bogie configuration,Fig 4 shows a three-car four-bogie configuration,Figs. 5 ,6 and 7 show arrangement of the vehicle over the bogies andFigs. 8 and9 show mounting of the cars on the bogies. - The low-deck rail vehicle, particularly a tram car illustrated in
Fig. 3 is arranged in two-car configuration with sections A and B and three bogies. - The vehicle in
Fig. 4 . is extended by one section and has four bogies. - The articulated tram vehicle shown in
Fig. 3 is equipped with the first endrotable bogie 1 under the front part of section A and thesecond end bogie 1 under the rear part of section B and onemiddle bogie 2 under the articulation - link between sections A and B of the vehicle, while both the adjacent ends of the bodies - sections A and B of the vehicle are rotably mounted on the middle bogie, each in aseparate mounting point 3. - The location of the bogies is illustrated in
Figures 8 and9 .Bogies - Thanks to this arrangement the deck over the bogies may also be kept in the standard low level, which is only slightly higher than the rest of the passenger space floor, while both the parts of the floor are connected with a barrier free transition part by slightly elevated ramps, while the passing width of the vehicle remains standard.
- Connection of the individual sections of the body with the bogies is based on the principle that the
pivot point 3 of themiddle bogie 2 is always geometrically located on the vertical axe going through the centre of rotation of the common rotation axis of one pair of the wheels, and thepivot point 4 of theend bogie 1 is vertically situated on the lengthwise axis of the bogie relatively close (approx. 1/3 of the bogie wheel base) to the centre of the common rotation axis of the pair of wheels more distant from the vehicle end, which minimizes the relative transversal movement of the appropriate wheels against the vehicle body during rotation around the vertical axis going through thepivot point 3 and possibly through thepoint 4 of attachment of the vehicle body on the appropriate bogie, which enables just a smaller restriction of the passing width W and Z of the vehicle, then is usual for other vehicles with rotable bogies, while the W dimension remains at the standard passing width of the vehicle. - For the
end bogies 1 under the front and rear parts of vehicle this advantage only applies to the pairs of wheels closer to the centre of the vehicle, the outer parts show higher range of movement against the vehicle body - however these pairs of wheels do not restrict the passenger space as they move under the driver's cabin at the front and under conveniently arranged seats at the back. The seats in the back part of the vehicle are arranged into arch shape over the space where the outer pair of wheels of thebogie 1 moves, seeFig. 7 . The width Z of the passage to the driver's cabin or to the seats at the back will remain acceptable, adequate to the intensity of passenger frequency at these areas. - Each section of the vehicle body mounted on the
middle bogie 2 is mounted by means of a bearing 7, which may be solved as an axial ball bearing or a tilting spherical bearing arranged on acradle 8, seeFig. 8 , while both thecradles 8 on themiddle bogie 1 are connected by alongitudinal rod 9 transferring longitudinal forces between the vehicle sections. Therod 9 arrangement and its attachment to thecradles 8 enable the adjacent section to move mutually along the longitudinal and transversal axes within the directional and vertical guiding of the rails. If spherical bearings are used for attachment of the body sections on the cradles, both the cradles may form a single solid unit, as the mutual movements of the sections around the longitudinal and transversal axes will be enabled in the spherical bearings 7. The longitudinal forces from the vehicle body sections to the bogie are transmitted by arod 10 connecting each of thecradles 8 of themiddle bogie 2 with theframe 11 of themiddle bogie 2. - At the
end bogies 1 the appropriate section of the vehicle body is mounted on the bogie by means of abearing 14 and acradle 12 with longitudinally shifted mounting of thebody 4 against thesecondary springing sets 13 and thus against the bogie centre. An axial ball bearing 14 is used at theend bogies 1 for attachment of the vehicle body section, as it is capable of transferring the moment caused by eccentric load on the cradle. - The arrangement of both the bogie types of a low-deck articulated rail vehicle, particularly a tram, according to the invention will enable a
low deck 15 to be kept all through the vehicle length at the standard level usual for low-deck trams, even over the bogies, while the floor is stepless, only with ramps with gradual elevation of maximum 1 : 10, while the passing width of the vehicle over the middle bogies remains at least standard and over theend bogies 1 is 70 % of the standard width, while the vehicle shows very good driving properties thanks to the use of primary and secondary springing, and the vehicle shows very good driving properties and minimum wear of wheels and rails, thank to the rotable mounting of the vehicle body on the bogies, which is unusual for low-deck vehicles. The wheels of all the bogies may be driven and braked by disc brakes. - The solution according to the invention is applicable for low-deck rail vehicles, particularly for trams designed mainly for municipal transport.
