Description
Carrying bogie for rail vehicles
The invention relates to bogies for rail vehicles, in particular high-speed rail vehicles.
Due to the increased travel speeds of rail vehicles, increased demands are also placed on the pivoted bogies of these vehicles, since the pivoted bogies are the main carrying units of the carriages. The pivoted bogie absorbs the weight of the body and the braking forces generated by each wheelset. When a pivoted bogie is moved across a straight or curved track section, it absorbs vertical and horizontal forces which are produced upon interaction of the wheelsets with the rails.
A carrying bogie for high-speed trains is known from RU 2454342 C2, said carrying bogie being embodied such that brake and suspension equipment can be accommodated thereupon and it is equipped with two wheelsets mounted on the frame.
In such cases each wheelset contains a shaft, two wheels fastened to the shaft by means of press fitting and a main brake disk arranged on the wheelset shaft and three additional brake disks likewise mounted on the shaft, said brake disks being arranged at the same distance from the main brake disk on both sides of
JN the same, wherein the hubs of all brake disks are fastened to the shaft by means
S of press fitting. The operative part of each brake disk is dismountably fastened
N to the hub with fastening elements and ventilation ducts formed through cooling = ribs are provided in the operative part of each brake disk. The frame is formed
T 30 by two longitudinal carriers bent downwards in the central part and a transverse z carrier, said transverse carrier connecting the central longitudinal carrier parts
S with one another, wherein provision is made on the longitudinal carrier for 2 fastening elements for two wheelsets and on the transverse carrier for fastening 5 elements for disk brake equipment, wherein three afore-cited equipment
N 35 elements are arranged on both transverse carrier sides in each instance. An opening for process control purposes is provided in the transverse carrier part,
by way of which opening installation of elements of the lemniscate mechanism can take place.
The object underlying the present invention is to specify a carrying bogie which is characterized by suspension comfort and could enable its use for high-speed passenger trains.
The object is achieved with a carrying boogie according to independent claim 1.
Furnishing the carrying bogie with three ventilated brake disks which are arranged at the same distance from one another allows for optimization of the braking processes, an increase in the brake efficiency and improved cooling of the brake system elements.
The frame with bent out longitudinal carriers and only one transverse carrier with an opening for process control purposes, by way of which installation of a lemniscate control lever can take place, contributes to reducing the starting resistance during travel and to a more effective absorption or transmission of braking forces. The presence of additional fastening elements allows for the use of disk brake equipment. All afore-described measures allow for an increase in the rail vehicle speed.
The invention is explained in more detail with the aid of Figures, in which, by way of example;
JN Fig. 1 shows a plan overview of the inventive pivoted bogie in a top view;
S Fig. 2 shows a plan overview of the inventive pivoted bogie in a side view. 5 + The exemplary pivoted bogie according to the invention is to be used for HGV
T 30 rail vehicles, wherein in order to facilitate use and maintenance it is z advantageous if all pivoted bogies have modular designs. The main modules of
S the driven and carrying bogies are to comprise the same embodiment as afar 3 as possible. &
The embodiment of the inventive carrying bogie 1 for high-speed rail vehicles allows for brake equipment and suspension to be accommodated on the pivoted bogie and contains two wheelsets 2 fastened on the frame 3.
The wheelset consists of a shaft, two wheels and three brake disks arranged symmetrically on the wheelset shaft.
The hubs of all brake disks are fastened on the shaft by means of press fitting.
The operative part of each brake disk is dismountably fastened on the hub with fastening elements. The operative part of each brake disk has two braking surfaces, wherein the effective heat dissipation therefrom takes place by way of ventilation ducts formed through cooling ribs.
The arrangement of the brake disks in the space between the wheels 4 and at the same distance from one another allows for a reduction in dynamic and temperature loads for wheels and brake system elements 4 and for a more effective distribution or use of braking forces with a significantly shorter rail vehicle braking path.
The press fit of the wheels on the shaft takes place in the cold state. Prior to press fitting the wheels and the brake disks, the surfaces of the clearance holes and the installation positions on the shaft are coated evenly with a lubricant, said lubricant ensuring the conductivity of the fit locations and not effecting a reduction in the creep resistance of the shaft.
JN The free surface of the shaft and the wheels is painted with primer and then with
S top coat. The painting protects the surfaces from corrosion. Each axle socket
N unit can be eguipped with a temperature sensor, from which information can be = transmitted in real-time mode to the control console of the rail vehicle, as a result
T 30 of which continuous monitoring and regulation of braking and starting processes z is enabled during the journey. > 2 The frame 3 of the carrying bogie 1 for a high-speed rail vehicle consists of two 5 longitudinal carriers and a transverse carrier. The frame 3 of the carrying bogie
N 35 is connected to the body by means of adapter 11.
Each longitudinal carrier is bent downwards in the central part. The transverse carrier connects the central parts of the two longitudinal carriers with one another. The use of the offered construction of just one adequately stiff transverse carrier (instead of two transverse carriers as is the case in the known constructions) allows for a reduction in the frame weight and an optimized distribution of braking forces which develop during the rail vehicle travel. The peculiar outer shape of the frame as a result of the bent out longitudinal carrier likewise contributes to optimizing the distribution of the braking forces and also results in a reduction in the aerodynamic resistance.
Fastening elements such as supports for two wheelsets are provided on the longitudinal carrier. Fastening elements such as supports for the disk brake equipment 4 of each wheelset are provided on the transverse carrier.
The possibility of using brake disks for each wheelset significantly increases the brake efficiency, as a result of which use of the offered frame for high-speed passenger trains is enabled.
An opening is provided in the central part of the transverse carrier for procedural purposes, by way of which the installation of lemniscate control levers can take place. The presence of the opening for procedural purposes on the one hand enables an increased frame stiffness and optimized distribution of braking forces and on the other hand a reduction in frame weight and dimensions as well as optimization of the arrangement of modules and components of the carrying bogie and an improvement in its aerodynamics. Positions for installing the
JN springs of the suspension primary stage are provided at the ends of the
S longitudinal carrier. 5 + The secondary vertical suspension is realized with pneumatic springs 10.
T 30 z The pneumatic suspension in each pivoted bogie consists of two pneumatic
S spring systems. An additional air tank is connected directly to the pneumatic 2 springs, said air tank being fastened to a body traverse above the pivoted bogie. = In order to compensate for different states, the state is regulated for the
N 35 secondary suspension stage by the pneumatic spring controller.
In order to increase the body roll stability, body roll stops are provided.
If one of the pneumatic springs fails, the body can be cushioned by emergency springs. 5 The two-stage suspension embodiment allows for achievement of a more effective absorption or transmission of braking forces and of the optimized ergonomic properties for the high-speed rail vehicles.
For improved yaw damping, dampers are provided, the transverse damper 7 and the vertical damper 8 and the body roll system 9.
Moreover, the carrying bogie 1 is equipped with a yaw damper 6, which is connected at one side to the frame 3 and at the other side to the support 5, which is formed independently of the frame 3 and is connected to the body.
On account of the different adjustment of the pivoted bogie to the mass and center of gravity of the individual carriages, and the different spring adjustment, the pivoted bogies are however only freely changeable within the same carriage type nevertheless without changing settings.
The offered design and arrangement of elements of the carrying bogie to be patented thus enable the use of the same for high-speed passenger trains by simultaneously reducing the frame weight, increasing the absorption or transmission efficiency for the braking forces, by increasing the braking efficiency and improving the ergonomic properties and on account of improved
JN suspension comfort and improved yaw stability with an increased speed of the
S rail vehicle.
