    Wheelset bearing for the wheelset of a1 rail vehicle with internal Drehges part
    Technical area
    The invention relates to a RadsatzLagerung for the wheels of a Schieneehfahrzeügs with ihhengelägertem bogie, 10 comprising - a bearing housing: per side of the wheelset, which surrounds the wheelset for a wheel, with wheelset and bearing housing in the assembled state: are within the wheels, 15 - a Torsion spring serving as roll stabilizer: connected to the bearing housing .:
    A wheel set for rail vehicles consists of the wheelset shaft and. the two wheel discs, or wheels.:. On the 20 axles can also brake discs or
    Drive components to be mounted. The wheelset is stored in the bogie by the wheelset bearing. In railway vehicles, the two wheels of a wheelset are usually firmly connected to the shaft 25 because of the sinusoidal rotation and thus rotate together. Therefore one speaks here of wheelset and accordingly from RadsatzLagerung. The wheelset bearings guide the wheelset laterally in the bogie and also transmit longitudinal forces when the wheelset is driven or braked. The wheelset bearing is usually designed as a rolling bearing, which sits in Raditztlägergehäuse and receives the wheelset.
    State of the art 35
    In rail vehicles - but also in other vehicles - the car body is usually resiliently mounted over the wheelsets via one or more spring stages. Due to the comparatively high center of gravity of the car body, the tendency of the car body to tilt towards the outside of the wheelsets, ie also a change in direction, is caused by the centrifugal acceleration which occurs transversely to the driving movement and thus transversely to the longitudinal axis of the vehicle. to parallel to the vehicle longitudinal axis: Wankaehse: execute. Such movements: above a certain limit, roll motions are detrimental to ride comfort; on the other hand, they bring about the risk of injury to the permissible clearance gauge and in terms of safety
    Ent g le i suug s sure it unacceptable ^ one-sided wheel relief: with itself.
    To this, too. As a rule, 15 anti-roll devices are used in the form of so-called anti-sway heaters. Their task is to resist the rolling motion of the car body to reduce it, while the Hub ™ and diving movements of the car body against the. Radsätzen or the chassis should not be hindered 20. As Lauf- or chassis is the
    Part of a rail vehicle, with which the vehicle runs on the rails and is guided. As bogie a drive with two or more arranged in a frame wheelsets is called. 25:
    Such roll stabilizers are known in various hydraulic or purely mechanical embodiments. Often comes a: transversely to the vehicle longitudinal direction extending torsion, which is also referred to as a torsion bar or torsion spring 30, is used, as it is known for example from DE: 1 98 19412 CI.
    On this torsion shaft sitting on both sides of the vehicle longitudinal axis rotatably mounted levers extending in the vehicle longitudinal direction .: These levers are in turn connected to links or push rods, which are arranged kinematically parallel to the spring means of the vehicle. During compression of the spring means of the vehicle 3/21 3 20: 122.3296 the seated on the torsion shaft are put on the handlebars connected to them in a rotary motion. If there is a roll motion with different spring travel of the spring devices on the two sides of the vehicle, the result is: different angles of rotation of the levers sitting on the torsion bar. The torsion wave is accordingly subjected to a torsional moment which, depending on its torsional rigidity, is compensated for a given torsion wedge 10 by a counter-torque resulting from its elastic deformation and thus prevents further rolling motion. In the case of rail vehicles equipped with bogies, the anti-roll device may be provided for both the secondary spring springs, that is, for the secondary suspension. H. between a 15 chassis frame and the car body act. Likewise: the anti-roll device can also be used in the primary stage / d. H. Between the wheel units and a chassis frame, as in DE 19819412 Gl, 20 Innengelagerte: bogies, where the axle bearings and the frame parts are located between the wheels or wheel discs, guer to the direction of travel smaller dimensions than externally mounted bogies, thus offer internally mounted bogies Correspondingly lower base for the 25 support of the primary spring stage. If the stiffnesses of the primary springs are similar to those of externally mounted bogies, the roll angle increases and the vehicle can come into conflict with the kinematic gauge. The kinematic gauge defines the maximum 30 recordable spaces of vehicles to ensure that they remain within the Infrastructure Light Trap. For this purpose, the maximum possible movement of the vehicle is considered, both lateral and vertical1 vehicle movements are taken into account, which are calculated based on the vehicle geometry and the suspension properties under different loading conditions. 4/21 4 2012: 23296
    A key feature of roll stabilization is the installation of a primary WanksLabilisator - with; Torsion springs, levers, train-pressure Langen and a bearing for the torsion spring on the bogie frame - even with internally mounted bogies 5 between the wheels, as just shown in DE 19819412 CI. Such roll stabilizers but with the different. Another solution for reducing the roll angle and thus increasing the roll stiffness is that instead of using a roll stabilizer, the primary spring stiffness is increased. However, this has the disadvantage that higher accelerations occur on the car body 15, which reduces the comfort for any passengers.
    DESCRIPTION OF THE INVENTION It is therefore an object of the present invention to provide a wheelset bearing or an internally mounted bogie which does not increase the dip stiffnesses of the primary suspension, but rather uses a torsion spring which has as little as possible a simple roll stabilization for the wheelsets.
    This object is achieved by a Radsatzlagerung with the features of claim 1. Advantageous embodiments of the invention are defined in the respective dependent claims. 30:
    The wheelset bearing according to the invention, for the wheelset of a rail vehicle with innengelagertem bogie./ comprises - one bearing housing per side of the wheelset, which surrounds the wheelset for the wheelset, where wheelset and 35 bearing housing in the assembled state 'are within the wheels, - as Roll stabilizer serving torsion spring which is connected to the bearing housings. 5/21 5 5 201223296
    In this case, it is provided according to the invention that the torsion spring is rigidly connected to one bearing housing at each of its two ends-without the interposition of pull-push rods.
    The torsion spring is thus rigid and thus rotatably connected to the two bearing housings, while conventional torsion springs are connected via levers and joints with the bearing housings and thus at their ends at least rotatably connected to the 10 bearing housings. The inventive storage of Tors i ons f'eder takes place exclusively via the connection to the wheelset bearing housing, briefly referred to as the bearing housing instead. 15 The wheelset, so the connection and power transmission of the invention Radsatzlagerung to the Dfehgestellfahmen, can be done in many ways. Thus, the power transmission can take place by means of separate coupling elements (z.13 bushings or link) or also directly via the primary spring elements themselves. A common and advantageous embodiment is the so-called rocker: in which the RadsatzlagefgehäUse is articulated via a Radsatzführungsbuchso with the bogie frame. 25 The wheelset housings may also have extensions which point away from the wheel axle and the torsion spring may be attached to these extensions. The wheel axle is the straight line passing through the centers of the two bushes: ·: 3Ö:
    The middle section of the torsion spring is usually disordered at a distance from and parallel to the wheel arch: As a particularly favorable design, the arrangement proves to be an arrangement in the vicinity of the connecting line between the wheels, if the wheel set guide is designed as a rocker arm both:
    Radsatzführungsbuchsen, since here the bending component is small in the twisting. In the vicinity of the connecting line, it should be understood that the middle section of the 6/21 6 201223296
    Torsiohsfeder is arranged closer to this connection line than in the wheel axle and / or that the central portion of the Torsiohsfeder has approximately the same radial distance from the wheel axle as the connecting line. .5
    The ends of the torsion spring are torsionally rigid and free of play connected to the bearing housings.
    A particularly simple embodiment provides that the IQ: Tors Ions spring manufactured in one piece and directly with; one each
    Bearing housing is connected, that is hergesteilt from a piece of a particular material. Your; Both ends are then deviating from the longitudinal direction of the torsion spring, so that they can be connected to the bearing housings 15 and thus can build up the torsional moment with different compression of the two rare. The middle section of the torsion spring, ie the torsion spring without the ends, then takes over the torsional moment. In the case of the one-piece manufacture of the torsion spring, the ends of the torsion spring may be formed by bending relative to the central portion of the torsion spring. For example, a straight metal rod is given the desired shape by bending at a location near its ends. The middle section of the Torsiohsfeder is bent over sin longer than sin.es end.
    However, the roll stabilizer can also be made of several parts by at the ends of the torsion spring Hebei 30 are firmly joined to the torsion spring and enclose an angle with the longitudinal direction of the torsion spring .. Thus, the lever with the torsion spring, ie the middle Ber ei eh of the roll stabilizer, force "or positively connected. The torsion spring will be formed in this embodiment in 35 usually over the entire Dange straight.
    In principle, the torsion spring as well; If applicable, the levers for fastening the torsion spring to the 7/21 7 20: 122329 6
    Lagerqohäuson be prepared by means of various Herstellungsüngsverfahren, such. as a milling, welding, casting or forging. In a multi-part WanksLabi.lisator, consisting for example of a torsion spring and levers, several different manufacturing processes can be used.
    A simple embodiment of the invention provides that at least (namely in the one-piece torsion spring), the central portion of the torsion spring is rod-shaped. That is, the central portion is straight, has the same cross-section over its length, approximately circular, and its length is a multiple of its diameter. The: Torsion spring is usually made in this simple form of: spring steel .. In the case of a multi-part Wankstahilisators consisting of a torsion spring and levers, the entire Tors Ions f.'eder be formed rod-shaped.
    The torsion spring can also take on additional functions in addition to the roll stabilization, such as. [5th serve as a carrier for one or more brake actuators, For example, on the torsion spring, Fixed caliper brakes, which can then be brought in the assembled state (with wheelset) with brake discs on the wheelset engaged.
    If the wheelset bearing according to the invention is provided with a wheel set, then one or more brake disks can be fastened correspondingly on the wheelset.
    If a RadsaLx1agerung invention is installed with a wheel in an internally mounted bogie, it can be provided that; the bearing housing is articulated via a Radsatzführungsbuchse articulated to the bogie frame, while there is no direct connection between bogie frame and torsion spring. This makes a difference to Wankslab: Iators from the state of 8/21 201223296
    Technique because there: Tors i ons foder is usually connected via a rotary connection with the bogie frame.
    In this case, the middle part of the torsion spring may be arranged parallel to the wheel axle 5 in the vicinity of the connecting line between the two wheelset guide bushings.
    A variant of the invention is there in that in each Radsatzführüngschuchse a bearing for connection to the IQ: frame of the bogie is provided., Wherein the axes of rotation of the bearing form an angle with the central portion of the TorsIonsfeder. The angles are the same for the two bearings of a wheelset and symmetrical to the longitudinal center plane of the bogie. 15
    This inclination of the bearing axes has the same effect as an inclination of the train-pressure long in a prior art torsion spring: The train push rods of a torsion spring are usually in a vertical plane 20 (ie, a plane normal to the axis of the torsion spring) arranged parallel to each other , Now, when the torsion spring facing away from the ends of the push-push rods are moved outward, close the train push rods - seen in the transverse direction - with the vertical © anen angle. In a transverse movement of the car: the: rail vehicle, this leads to a stiffer supporting the car and thus the Wankbewegunq is reduced.
    Also, the slanting position of the Lagoon axles causes * that at 30 a transverse movement of the carriage, which is indeed mounted on the bogie, a rotational movement is induced in the bearings, but does not lead to a perceptible rotation, but only the torsion spring bias 1. This is it an increase in the stiffness of the torsion fader.
    In addition to or as an alternative to using the
    Wankst.abilisat.ors as a carrier for brake actuators may be provided that: at least the middle section of the 9/21 35 9 2012: 23296
    Torslonsfeder part of a Dreomomont: abst: use for a wheelset is when a Radsatzlagerung invention is installed with a set of wheels in an internally mounted bogie. The drive torques 5 are then supported directly on the roll stabilizer and not, as usual, introduced into the bogie frame »
    The invention uses the principle of primary
    Wankstäbilisatoren, but waived the pull-push rods IQ: and the separate storage of the torsion spring on another
    The torsion spring is directly connected to the wheelset housings of the bogie The function of supporting the torsion spring on the bogie is replaced by the connection to the wheelset bearing housings 15
    Compared to conventional Wanks1ab systems there is an advantage in terms of cost, technical complexity and weight, because the train-Drucksfangen, their bearings and the storage of Torslonsfeder omitted. The 2: 0 system according to the invention is thus lighter and more compact. If the: structure of the torsion spring offers appropriate connection points ,: this can also take on additional functions such as the connection of brake actuators (caliper brakes) and / or a torque support of a drive. 25
    The inventive Radsatzlagerung is not limited to one per chassis or bogie. There may be several such Radsatzlagerungen, usually two, per chassis. 30
