    Spring arrangement for a rail vehicle
    The invention relates to a spring arrangement for a vehicle, in particular a rail vehicle with at least one car body and at least one chassis.
    In the case of local and regional transport vehicles in particular, the height of car bodies is often regulated in order to achieve a low boarding height or a level entry into the vehicle for passengers, for example, when staying in stations.
    In vehicles where the secondary spring is not as
    Air spring, but is designed for example as a coil spring, the height can be adjusted by pulling down the car body against the action of the coil spring, with large forces having to be applied.
    DE 10 2015 016 024 Al is known from the prior art, for example. It describes a spring system for a rail vehicle with a spring strut. The spring strut has a hydraulic cylinder with a piston guided therein, the piston being connected to a suspension spring between a car body and a chassis. Depending on the pressure conditions in the hydraulic cylinder, a height of the suspension spring or a spring travel is influenced.
    Furthermore, DE 103 15 000 A1 discloses a level control for a rail vehicle, in which an actuator acts on a spring step between a car body and a substructure in such a way that the car body can be lowered and raised against a restoring force of the spring step.
    The invention is based on the object of specifying a spring arrangement which is further developed compared to the prior art.
    2.24
    201701028
    According to the invention, this object is achieved with a
    Spring arrangement of the type mentioned in the introduction, in which at least one suspension spring, at least one preloaded relief spring, one connected to the at least one relief spring
    Contact bodies and at least one first additional spring are provided, in which a first longitudinal axis of the at least one suspension spring, a second longitudinal axis of the at least one relief spring, a third longitudinal axis of the contact body and a fourth longitudinal axis of the at least first additional spring are arranged parallel to one another, and that the contact body between the at least one
    Relief spring and the at least first additional spring is arranged.
    Thereby for a height regulation, i.e. achieved a low overall stiffness of the spring arrangement in a stop operation of the vehicle without the stiffness ratios of the spring arrangement in a running operation of the vehicle i.e. e.g. impairment while driving.
    Will the spring arrangement for the height adjustment of the
    Car body used and the suspension spring is arranged between the car body and the chassis, are due to the low overall rigidity for lowering the
    Car body required forces reduced.
    As a result, components of the spring arrangement (e.g. a hydraulic cylinder which applies forces against the suspension spring and the first additional spring via hydraulic pistons for height regulation and thus pulls the car body down, for example) can be made light and compact.
    It is favorable if a first hydraulic piston, which contacts the at least one relief spring arranged in the hydraulic cylinder, projects into a hydraulic cylinder.
    3.24
    201701028
    It is furthermore advantageous if, projecting into the hydraulic cylinder, a piston rod connected to the at least one running gear is arranged.
    By designing the hydraulic cylinder as a housing for the relief spring, a particularly compact arrangement is achieved on the one hand and on the other hand with the
    Hydraulic cylinder generates high pressures.
    With the hydraulic cylinder are about the first
    Hydraulic pistons, forces are applied to the piston rod, causing the body to be lowered.
    An advantageous embodiment is obtained if a second hydraulic piston, designed as a driver with respect to the first hydraulic piston, is arranged in the hydraulic cylinder and is connected to the piston rod via a compression spring.
    This results in a series connection of the first hydraulic piston with the second hydraulic piston. The first hydraulic piston acts on the relief spring and the second hydraulic piston on the piston rod. If the piston rod is connected to the undercarriage or to the car body, this leads e.g. while the vehicle is moving, dynamic movements of the undercarriage or the body of the vehicle are also off. Since these movements act on the second hydraulic piston via its connection to the piston rod, the relief spring is decoupled from it and can therefore be made compact.
    The invention is described below with reference to
    Exemplary embodiments explained in more detail.
    The following are examples:

    201701028
    A first exemplary shown in FIG. 1
    A variant of a spring arrangement according to the invention has a support spring 1 designed as a steel coil spring with a base plate 16 and a cover plate 17. The
    Cover plate 17 is one with a car body
    Rail vehicle connected, the base plate 16 via a second additional spring 5, which is designed as a layer spring, with a chassis. Provided within the suspension spring 1 is a prestressed relief spring 2, which is designed as a steel coil spring and is arranged in a housing 18. The housing 18 is connected via its upper side to the cover plate 17 and has an opening through which a contact body 3 designed as a stamp and connected to the relief spring 2 is guided to the outside. The contact body 3 is thus mounted between an underside of the housing 18 and the relief spring 2.
    Arranged underneath the contact body 3 and likewise within the suspension spring 1, a first additional spring 4 designed as an elastomer spring or a rubber buffer is provided, which is connected to the base plate 16 via its underside. A first longitudinal axis 6 of the suspension spring 1, a second
    The longitudinal axis 7 of the relief spring 2, a third longitudinal axis 8 of the contact body 3, a fourth longitudinal axis 9 of the first additional spring 4 and a fifth longitudinal axis 10 of the second additional spring 5 are arranged congruently with one another.
    FIG. 2 shows a spring diagram (force / displacement, F / s diagram) with respect to the arrangement shown in FIG. 1.
    If the suspension spring 1 is compressed, the contact body 3 contacts the first additional spring 4 after overcoming a distance ds shown in FIG. 1, as a result of which a series connection of the relief spring 2 with the first additional spring 4 is generated. The relief spring 2 and the first additional spring 4 are connected in parallel with the suspension spring 1.
    If a contact force between the contact body 3 and the first additional spring 4 exceeds a biasing force FV of the relief spring 2, the increase in a total spring force becomes
    6.24
    201701028
    FG, which is made up of a spring force FT, one
    Relief spring force FE and a first additional spring force FZ composed, due to the different courses of FT, FE and FZ shown in FIG. 2 and the series and parallel connection mentioned reduced.
    This has the advantage that the forces required for lowering the car body, which must be applied against the total spring force FG, for example by a hydraulic cylinder 11 shown in FIGS. 3 and 4, can be reduced.
    For lower forces than FV (driving operation), the
    The spring arrangement has a different stiffness curve than for larger forces (stop operation).
    FIG. 3 shows a second exemplary embodiment variant of a spring arrangement according to the invention, the same reference numerals as in FIG. 1 being used.
    In contrast to FIG. 1, FIG. 3 shows a housing 18 which is designed as a hydraulic cylinder 11. The hydraulic cylinder 11 is connected via its upper side to a cover plate 17 of a suspension spring 1. The cover plate 17 is connected to a car body.
    The hydraulic cylinder 11 is sealed from its surroundings by a seal 19.
    Via a hydraulic connection 20 and a line path 21, a contact body 3 designed as a first hydraulic piston 12, which contacts a relief spring 2, is actuated by means of a defined pressure of a hydraulic fluid 22.
    The left area of FIG. 3 shows an unactuated state of the hydraulic cylinder 11, the right area an actuated state.
    Coaxial with the first hydraulic piston 12 is one
    Piston rod 14 arranged. The first hydraulic piston 12 and the piston rod 14 protrude into the hydraulic cylinder 11.
    In the actuated state of the hydraulic cylinder 11, the first hydraulic piston 12 is in comparison to the unactuated one
    7.24
    201701028
    State raised and contacts the piston rod 14, whereby it can move with the first hydraulic piston 12 upwards.
    The piston rod 14 is connected to a chassis via its underside. According to the invention, it is also conceivable to connect the piston rod 14 to the car body.
    If the first hydraulic piston 12 moves upward, the relief spring 2 is compressed on the one hand and, on the other hand, the distance between the car body and the undercarriage is reduced via the movement of the piston rod 14. In this way the height of the car body is adjusted.
    In the case of a contact, not shown in FIG. 3, between the first hydraulic piston 12 and a first additional spring 4 arranged beneath it, on a base plate 16 of the suspension spring 1 connected to the chassis, there is a preload of the relief spring 2
    Reduction of the forces to be applied by the hydraulic cylinder 11 against the action of the suspension spring 1 and the first additional spring 4 for height regulation, as described in connection with FIGS. 1 and 2.
    4 shows a third exemplary embodiment variant of a spring arrangement according to the invention, the same reference numerals as in FIG. 1 and in FIG. 3 being used.
    Fig. 4 shows a housing 18 which is designed as a hydraulic cylinder 11. The hydraulic cylinder 11 is connected via its upper side to a cover plate 17 of a suspension spring 1. The cover plate 17 is connected to a car body.
    The hydraulic cylinder 11 is sealed from its surroundings by a seal 19.
    8.24
    201701028
    Via a hydraulic connection 20 and a line path 21, a first hydraulic piston 12, which contacts a relief spring 2, is actuated by means of hydraulic fluid 22.
    The left area of FIG. 4 shows an unactuated state of the hydraulic cylinder 11, the right area an actuated state.
    In contrast to FIG. 3, a second hydraulic piston 13 is arranged in the hydraulic cylinder 11, which is also actuated by means of a hydraulic fluid 22, the same pressure acting on the first hydraulic piston 12 and the second hydraulic piston 13.
    The second hydraulic piston 13 is with the first
    Hydraulic piston 12 connected in series.
    The first hydraulic piston 12 acts on the
    Relief spring 2 and the second hydraulic piston 13 on the piston rod 14. The piston rod 14 is connected to the chassis and therefore leads, e.g. while the vehicle is moving, dynamic movements of the chassis with off. Since these movements act on the second hydraulic piston 13 via its connection to the piston rod 14, the relief spring 2 is decoupled from it and can therefore be made compact.
    When the second hydraulic piston 13 moves upward, the first hydraulic piston 12 also moves upward and compresses the relief spring 2.
    The second hydraulic piston 13 is connected to the piston rod 14, a compression spring 15 being arranged between the second hydraulic piston 13 and the piston rod 14.
    When the second hydraulic piston 13 moves upward, the piston rod 14 also moves upward through this connection.
    As already mentioned in connection with FIG. 3, a movement of the piston rod 14 brings about a height regulation of the car body.
    9.24
    201701028
    The compression spring 15 causes after actuation of the
    Hydraulic cylinder 11, i.e. when the pressure in the hydraulic cylinder 11 is reduced, the second hydraulic piston 13 is reset.
