Description
Technical field
The present invention relates to a kind of layout of the low floor tramway train for passenger traffic, be designed for municipal traffic especially.
Background technology
Low floor tramway train is fabricated to has low floor on whole Vehicle length, and the height of this floor on track top in the scope of 350 ÷ 450 millimeters can be considered to standard, and minimum sandards is 600 millimeters by width.In order to floor level being remained on this standard level place, the bogie truck of these tramway trains is equipped with off-axis beam (broken axle beams) usually, these blosters have independent install there are the several to wheel of common geometry rotation axis.These blosters with the independent wheel installed replace standard vehicle wheels (that is, be pressed on common axletree several to wheel), and can by the base plate at low floor level place, even if be also like this between the wheels.
But, under the occasion using rotatable bogie truck, when it is towards vehicle body around vehicle axial rotation, bogie support structure between wheel and wheel limits passenger space, make the part place of the width X of passenger space on bogie truck hard up, be therefore less than standard, see Fig. 1.
If low floor vehicle is made up of multiple sections (compartment), then under each odd number portion section, be attached the position of non-rotatable bogie truck, the width Y through the low floor of vehicle extends to standard level, see Fig. 2.But this is is cost with the wearing and tearing of higher wheel, because in this case, only have low bogie truck towards specific vehicle body around the rotation of vertical axis be possible (about 3 °).This causes the increase of the power between vehicle body and bogie truck and between wheel and track, because the most of rotary motion of portion's section on bogie truck is trapped in and guide rail contact place.And, compared with there is the vehicle of high floor level, these vehicles have lower quantity wheel group (to) because portion's hop count amount is low thus make the quantity of bogie truck also low, so the vertical load in a wheel group is higher, so just for operation is made troubles.
By the pivotal point of vehicle body being navigated to the vertical center of wheel group (a pair relative wheel), just can be used in passenger by width expansion, the vehicle body be simultaneously arranged on bogie truck keeps rotatable.The location of this mode of vehicle body on single bogie truck of the adjacent section of tramway train can be used in relatively being expanded by width of passenger.But, the occasion of such as dual spring suspension can not be equipped with at bogie truck, or the occasion of driver train (patent IT21163A/84) is not equipped with at these bogie trucks, or although driver train can be equipped with in these mechanisms but not have enough spaces for plate disc brake and bogie truck only has the occasion of stop drg (patent IT1216453), cause space problem equally for keeping the effort of low floor level on bogie truck.In two compartment vehicles, only have middle bogie can be resolved according to which.The floor that rotatable end bogies has wants high about 200 millimeters.
Summary of the invention
Above-mentioned shortcoming can be eliminated largely by the radial type low floor railroad vehicle of extension of the configuration of 2-compartment 3-bogie truck or at least one middle compartment and a middle bogie, and it is based on following principle: be always equipped with an end bogies and in each joint (namely under both front and rears of vehicle, connecting portion between vehicle car) under be always equipped with a middle bogie, simultaneously two adjacent vehicle bodies are rotatably installed on each middle bogie, and each is all arranged in its respective attachment point.
Bogie truck is arranged and is allowed the element of primary and secondary springing several in the space between the independent wheel installed, and allows actuator and drg to be positioned on the outside of wheel relative to longitudinal direction of car axis.Due to this layout, under floor on bogie truck also can be maintained at standard low-level, it is only a little more than the base plate of remaining passenger space, and two of base plate parts are connected with the accessible transition portion as the slope raised a little, simultaneously vehicle remain standard by width.The single portion section of vehicle body and the connection of bogie truck are based on following principle: the pivot point of two adjacent vehicle bodies of the vehicle on middle bogie is geometrically always being positioned on the vertical axis of centre of gration of the common rotation axis by pair of wheels, and the pivot point of end bogies is positioned on vertical relatively on (1/3 of about wheel-base bogie) this longitudinal axis to the center of the common rotation axis of wheel away from the bogie truck of vehicle end, this just decreases applicable wheel to greatest extent (this vertical axis is by the pivot point of middle bogie around vertical axis, and can by being applicable to the attachment point of the vehicle body on end bogies) in the process that rotates for the relative lateral motion of vehicle body, what this just can make vehicle is only subject to very little restriction by width W, and be generally used for other vehicle with rotatable bogie truck, namely, the size of the W on middle bogie remains on normal width place, and the size of the W on end bogies is close to normal width.
For the end bogies under the front and rear of vehicle, this advantage is only applicable to center several to wheel closer to vehicle, exterior section shows higher range of movement for vehicle body, but these paired wheels do not limit passenger space, because these wheels move in under-cab when front portion, move under the seat of facility layout when rear portion, such as, be arranged in the vault (see Fig. 7) spatially of outside pair of wheels motion.To be acceptable to operator's compartment or the passenger's width Z to the seat at rear portion place, it be enough to the intensity of the passenger moving met in these regions.
Each the section being arranged on the vehicle body on middle bogie is installed by means of bearing, it can be solved as cod or the oblique ball spherical bearing be arranged on bracket, and two brackets simultaneously on each middle bogie are connected by the bar transmitting longitudinal force between each portion section.Bar is arranged and is attached to bracket and adjacent section can be made mutually to move with axis of pitch along the longitudinal within the orientation and vertical guiding device of track.If globe bearing is for being attached at bracket by automobile body part section, then two brackets can form single solid element, because each portion section can be carried out around the mutual motion of vertical and horizontal axis under globe bearing.Transmitted by bar from automobile body part section to the longitudinal force of bogie truck, this bar connects each bracket of middle bogie and the vehicle frame of middle bogie.
At end bogies place, vehicle body is arranged on bogie truck by means of bearing and bracket, and it has the displacement erecting device of automobile body for elastic parts (and thus for bogie pivot center).Axial ball bearing such as here uses, for attached automobile body portion section, because it can shift the moment caused by the eccentric load on bracket.
Even if on bogie truck, layout according to bogie truck type of the present invention also can make low floor remain on standard level place on whole Vehicle length, base plate is wheel chair access simultaneously, only there is the slope of raising gradually being 1:10 to the maximum, vehicle simultaneously on middle bogie keep being at least standard by width, vehicle on end bogies be 70% of normal width by width, simultaneously owing to employing primary and secondary springing, vehicle shows extraordinary driving performance, and because automobile body is rotatably installed on bogie truck, vehicle shows extraordinary driving performance and minimum wheel and path wear, this is uncommon for low floor vehicle, and the wheel of all bogie trucks can be driven by plate disc brake or brake.
