Definitions

  • the present invention refers to a wheelset for railway vehicles, which is included in the railway transport sector.
  • the wheelset for railway vehicles object of the invention has as main purpose increasing the load of wagons or railway cars using a new development of an independent wheel system with a configuration of a double set of wheel axles, with a guiding system that allows the axle to correctly inscribe curves; and all this thanks to the combination of simple, reliable, low maintenance elements that ensure a quick implementation applicable to railway vehicles currently in use.
  • wheelsets related to the railway sector are currently known, whose main function is the ability to transport a plurality of containers for transportation of freight or cars for passengers on rails or railways.
  • the most common concept of wheelset consists of a set of two pairs of wheels mounted on two axles, which are close, parallel and interdependent, which are used at both ends of vehicles intended to roll on rails, known as bogies for railway vehicles.
  • wheelsets There are multiple mechanical and pneumatic elements belonging to the wheelsets and both associated with the type of load to be transported and to the rail on which the respective railway vehicles roll; see for example the case of freight transportation, where the most important thing is the load-carrying capacity as opposed to comfort, so the wheelsets present a reinforced structure and suspensions in order to support a greater load to be transported.
  • the aim is to achieve wheelsets capable of absorbing most of the irregularities of the railway, with the aid, in some cases, of pneumatic suspension systems associated with the boxes of the rail vehicles. In both cases, the performance of the wheelset must seek to reduce wear to the wheels.
  • a wheelset having two frames with mounted wheel axles, each one of which in turn comprises two wheels linked the one to another by a common axle attached to a chassis, wherein the two frames are linked together through an articulated support, such as that for trailer truck boxes, i.e., by means of a two-pivoted lever on both chassis, and allowing free rotation at an axis perpendicular to the larger surfaces of the chassis (gravitational direction):
  • an articulated support such as that for trailer truck boxes, i.e., by means of a two-pivoted lever on both chassis, and allowing free rotation at an axis perpendicular to the larger surfaces of the chassis (gravitational direction):
  • the independence of the movement of this wheelset is limited by the separation of the double anchoring of the two-pivoted lever.
  • each wheelset there are mounted axles instead of independent wheels.
  • the European patent no. EP-1789301-B1 describes a bogie formed by two wheelsets presenting respective wheels with independent axles, so that each wheel is attached to a separate sub-frame, which is subsequently attached to a main frame on which the respective sub-frames are fixed through attaching means allowing the relative movement in the gravitational sense of each wheel.
  • Such attaching means are of mechanical type, by means of gears, and have pneumatic or hydraulic control.
  • the present invention relates to a wheelset for railway vehicles comprising two sets of wheel axles, in which each set of wheel axles comprises two wheels, each wheel being located at each side of the wheelset according to a longitudinal axis of the vehicle, wherein the two wheels of each set of wheel axles have independent axes and are linked together by a frame; so that the two frames of the set of wheel axles are connected to one another by an articulation located in correspondence with the longitudinal axis of the vehicle and which allows to transmit tensile and compressive stress between the frames of the wheelset without modifying the distance between the axles of the pairs of wheels in each set of wheel axles.
  • the main body is a wheelset, which consists of two frames interconnected through an articulated articulation that restricts the degrees of freedom between the two, where each frame includes two wheels that rotate independently between each other, as each wheel is provided with their own axle connected to the frame through the corresponding grease boxes which support the axle ends of each wheel.
  • a bogie is a set of two pairs of wheel axles, close, parallel and interdependent through a common frame, which is used at both ends of vehicles intended to roll on rails.
  • a guidance system which allows the inscription on the track of the same, is also defined.
  • the wheelset comprises two frames that support respective pairs of wheels, where each wheel has an independent rolling axle ensuring the independent rotation there between.
  • the frames are coupled together by an articulation situated in correspondence to the longitudinal axis. This articulation allows the separate movement of both frames, not interfering with the guidance thereof, while restricting the relative movement there between in the longitudinal axis X and rotation about the axis Y.
  • coordinate axes which will help in explaining the invention are defined.
  • the articulation has certain restrictions in its displacement and in its movements, restrictions that are conditioned by the application itself where it is intended.
  • This type of configuration is expanded according to the scissor definition, which is defined as a physical entity composed of two cross pieces that revolve around an axis, real or imagined.
  • the ends of the cross pieces of the articulation are coupled to each chassis of the wheelset; where preferably the axis on which both cross pieces rotate is parallel or coincident with the second coordinate axis, and, thereby, each of the wheelsets is independent of the other and are mechanically linked due to the respective chassis and the scissor configuration.
  • the articulation comprises two curved rods which cross each other without contact and which are articulated by their ends with the chassis of the wheelset is described. Leading to an imaginary cross axis between the two curved connecting rods, and that, therefore there is no physical contact between them, which causes no friction or premature wear that requires ongoing maintenance on said articulation.
  • each of the curved connecting rods are coupled to the respective chassis by means of articulated joints; ensuring the independence of movement between both wheelsets during the movement of railway vehicles.
  • the wheelset of the invention comprises a system of guide rods which directly couple the frame with each one of the adjacent boxes of the railway vehicle is contemplated; this system allows the rolling axles to inscribe tangentially on the longitudinal axis of the track both on the straight and in curves, thereby eliminating the angle of attack that occurs between the wheel and rail.
  • the guiding system is independent for each of the frames, so that there is independence of rotation about the Z axis there between.
  • Said pair of guide rods having articulated ends in their respective couplings between the frame and each vehicle box, adapting to the path of the track and effectively absorbing its irregularities, besides being oriented, preferably, in parallel axis to the first coordinate axis X. And so that there are no unwanted collisions between both guide rods, they are in parallel planes to the plane formed by the first and second coordinate axes, XY plane.
  • each wheel of each wheelset is coupled to its respective frame through respective grease boxes.
  • each of the frames has a flat configuration and comprises two lateral recesses corresponding to the wheels; and thereby, the axle support of each of the wheels on the frame is permitted, without need for elements for fixing the wheels that communicate the rotation thereof.
  • each frame has a flat configuration and comprises a central elongated hole is contemplated; which further causes a decrease in raw material to be used in its manufacturing.
  • the wheelset is left supporting the two adjacent boxes of two adjacent railway vehicles, being between the two the highly effective, reliable and innovative in relation to the state of the art currently known.
  • the wheelset for railway vehicles thus obtained can solve the drawbacks described above; since it allows a high load capacity in railway vehicles, freeing the movement of each set of wheel axles, effectively and without interfering with the guidance system in curve of each one; so that a smoother and truer guidance with respect to the path of the railway track occurs; and all thanks to the combination of simple elements, reliable, and low maintenance that ensure quick servicing that is applicable to railway vehicles currently in use.
  • each set of wheel axles (1) comprises two wheels (2) being located each wheel (2) on each side of the wheelset along a longitudinal axis (3) of the vehicle, where the two wheels (2) of each set of wheel axles (1) have separate axis (4) and are linked together by a frame (5); so that the two frames (5) of the wheelset are connected together by an articulation (6) located in correspondence with the longitudinal axis (3) of the vehicle, and that allows the transmission of tensile and compressive stress between the chassis (5) of the wheelset without modifying the distance between the axis (4) of the pairs of wheels (2) of each set of wheel axles (1).
  • the articulation has certain restrictions in its displacement in its movements, restrictions that are conditioned by the application itself where it is intended.
  • connection of the connecting rods (6) to the sets of wheel axles (1) have been omitted.
  • each wheel (2) of each set of wheel axles (1) is coupled to its respective frame (5) through respective grease boxes (8).
  • On each side of the frame (5) a pair of guide rods (9) are joined directly and respectively coupled to the adjacent railway vehicles.
  • Such guide rods (9) totalling eight rods due to the existence of four wheels (2) for each frame (5); said guide rods (9) belonging to different mutually parallel planes to the plane defined by the first, x, and second, y, coordinate axes, and thereby not colliding with one another during operation.
  • each frame (5) has a flat configuration and features:
  • the preferred use for the wheelset, object of the invention is focused on allowing the support of two boxes of two adjacent railway vehicles on the same wheelset.
  • the preferred use for the wheelset, object of the invention is focused on allowing the support of two boxes of two adjacent railway vehicles on the same wheelset.
  • the configuration and connection of all physical entities allowing for a wheelset suitable for the support of heavy loads of the boxes of railway vehicles.
