Definitions

  • the present invention relates to a two-piece bogie isolating noise and vibration in low-floor railed system vehicles and improved for providing a balanced structure to the vehicle.
  • Railed systems can be classified as light rail systems, heavy rail systems, automatic systems, single rail systems and magnetic levitation systems.
  • vehicles have wheels; and vehicles are moved on the rails using said wheels.
  • light rail systems mostly light rail systems are utilized, and less frequently, heavy rail systems are utilized.
  • trams and light subway trains can be given as example.
  • These kinds of railed systems are the low-floor or high-floor systems.
  • light rail systems on the rails, there is a single vehicle or there are vehicles which are in connection to each other in short sequences.
  • bogie which is among the components forming railed system vehicles, carries out the most important function for the dynamics of the vehicle.
  • the bogie provides the wheel movements and at the same time it carries the remaining components of the vehicle.
  • the most important function of bogie is to provide flexibility in the structure by eliminating the rigid structure existing between the wheel axle shafts and the body during the non-linear movements of vehicles or during the movements of vehicles on deformed rails.
  • low floor railed system vehicles are used, and the height of these low floor railed system vehicles is generally up to 35 cm, and passengers can easily access the railed system vehicles without the need for a ramp or for a staircase.
  • said low floor railed systems some problems are faced. Since low floor is used, the vehicle wheels should be made smaller. If the vehicle wheels are made smaller, in cases where the vehicle follows a curved route, vibration occurs because of the lateral forces occurring in the vehicles. Moreover, the noise produced by the vehicle increases and because of said noise and said vibration, the comfort of the passengers and of the driver is deteriorated.
  • the vibrations of the vehicle are decreasing and the comfort of the vehicle increases both for the passengers and also for the operator.
  • the load applied to the chassis is decreased thanks to the flexibility of the structure and thereby metal fatigue is minimized, and the abrasions occurring in the rails and in the wheels are decreased.
  • the bogie comprises two flexible pieces, even if the rails are deformed in the vertical direction, the connection of the wheels on the rail is not interrupted and thus the risk of derailing is decreased.
  • Bogies can be classified in two classes, namely, classical bogies and advanced bogies.
  • Classical bogies comprise a rigid frame and thus they cannot provide the flexible structure required for the railed system vehicles which particularly move on non-linear paths.
  • the advanced bogies have various designs, and the most important difference between the advanced bogies and the classical bogies is that the advanced bogies comprise two frame pieces and these pieces are connected to each other by means of flexible members.
  • bogies In railed systems, vibration comfort is improved and depending on this, the noise formation and the negations in the passenger and driver comfort are eliminated by means of the selection of a suitable bogie, and additionally, by means of the usage of bogies with advanced suspension systems.
  • a suitably designed suspension system By means of a suitably designed suspension system, higher performance criteria can be provided depending on the changing load and road conditions.
  • bogies generally passive suspension systems are used and said suspension systems comprise two parts. One of these parts is the primary suspension connecting the wheel system to the bogie frame and the second one is the secondary suspension positioned between the bogie frame and vehicle body.
  • the primary suspensions comprise rubber pads.
  • the positions of the primary suspensions on the bogie are fixed, and the main function thereof is to dampen the vibrations between the wheels and the bogie.
  • the secondary suspensions are the air springs which are generally called "bellow". Air springs are structures formed by covering a bearing by an elastic rubber sheath and having gas therein. The dimensions of the air springs are small and they preserve the driving height and they provide vibration and noise insulation in order to eliminate the disadvantages faced in the low floor bogies. They have an important role in keeping the vertical position of the vehicle in a fixed position. The positions of the secondary suspensions on the bogies are changeable.
  • the applicant has a patent application 201 1/07418.
  • a two-piece bogie structure is disclosed in order to provide flexibility to the bogie structure and in order to decrease the vibrations occurring in the railed system vehicles.
  • the application numbered 201 1/07418 is improved for providing increase in vibration comfort.
  • the present invention relates to a two-piece bogie improved for isolating noise and vibrations occurring during the movements of low floor railed system vehicles, in order to eliminate the abovementioned problems and to bring new advantages to the related technical field.
  • the main object of the present invention is to provide a two-piece bogie having suspensions corresponding to the weight center of the vehicle, in order to be used in low floor light railed system vehicles like trams which are moving on non-linear rails and which are particularly used in city centers.
  • Another object of the present invention is to provide a two-piece bogie providing the engines to be positioned next to the bogie, in low floor railed system vehicles.
  • Another object of the present invention is to provide a two-piece bogie where big wheels can be used so as to decrease the vibrations in low floor railed system vehicles.
  • Another object of the present invention is to provide a bogie where the loads applied by the body are transmitted directly to the rails by means of the wheels without forming any momentum in order to reduce wheel abrasions.

Ce bogie (10) comporte des essieux montés (72), des pièces porteuses (20, 30), des sièges (23, 33), et un plateau de mise en place (234, 334). Les pièces porteuses (20, 30), qui sont réunies l'une à l'autre par une liaison articulée, sont montées sur les systèmes de roues (70) dans lesquels se trouvent les essieux montés (72). Le sièges (23, 33), qui sont réalisés dans les pièces porteuses (20, 30), sont caractérisés en ce qu'une telle pièce porteuse (23, 33) comprend une paroi (232, 332) définissant une hauteur d'assemblage (h) déterminée en fonction du rayon de roue (r). Le plateau d'assemblage (234, 334) est réalisé dans le prolongement de ladite paroi (232, 332) de façon à assurer une isolation contre les bruits et les vibrations prenant naissance dans lesdites bogies en deux parties pour voitures à planchers surbaissés (10).
