    Wheel for vehicles
    The invention relates to a wheel for vehicles, in particular for rail vehicles, which has a first wheel hub and a first wheel body with a wheel web, a wheel flange and a tread.
    Vehicle wheels must be exchanged quickly and easily for the purpose of maintenance and repair. Trolleys for rail vehicles with external or internal bearings are known from the prior art. These have wheels, which are often connected to wheelset shafts to form wheelsets via press fits. Wheel webs and wheel hubs of these wheels are often designed as inseparable units.
    If these wheels have to be replaced, for example, then those wheel sets with the wheels to be exchanged must be removed so that the wheels can then be pressed off using a wheel set press and new wheels pressed on. After changing the wheels, the wheel sets are reinstalled in the chassis. In particular with internally mounted running gear, installing and removing wheel sets can be very complex. This increases the lifetime costs of the running gear or the rail vehicles.
    For example, AT 514373 A1 shows a wheelset bearing system for internally mounted undercarriages of rail vehicles.
    DE 10 2011 117 444 B4 is also known from the prior art.
    A rail vehicle wheel is disclosed therein which has a wheel hub, a wheel plate and a wheel rim. The wheel plate is connected to the wheel rim by a toothing. The toothing is wave-shaped and arranged on the outer surfaces of the wheel plate and the wheel rim. The wheel plate positively engages the wheel rim. A fastening of the wheel plate on the / 24
    201703004
    The wheel rim is made using a snap ring, a locking ring and screws.
    A nut is arranged on a thread of the wheel hub, which axially braces the wheel hub and the wheel plate. These two components are also radially clamped to one another via a conical fit between the wheel hub and the wheel plate.
    The wheel hub can be non-positively connected to an axle shaft by means of a pressing process.
    The invention is based on the object of specifying a wheel which has been further developed compared to the prior art.
    According to the invention, this object is achieved with a wheel of the type mentioned in the introduction, in which at least one toothing is provided in at least one contact area between the first wheel hub and the wheel web.
    This has the advantage that the first wheel body can be easily assembled and disassembled. For disassembly, it is pulled off the first wheel hub with little effort. It is not necessary to press the entire wheel off a wheelset shaft. The first wheel hub can remain on the wheelset shaft during a replacement of the first wheel body.
    Furthermore, it is not necessary to remove a wheel set from a chassis for the purpose of changing wheels.
    The large amount of time required for installing and removing wheel sets, in particular in the case of internally mounted running gear, can be saved when using the wheel according to the invention due to the toothing between the first wheel hub and the wheel web.
    Due to a simplified and accelerated maintenance and repair, the lifetime costs for running gear or rail vehicles with wheels according to the invention decrease.

    The toothing is between the first wheel hub and the
    Wheel web arranged and thus has a small radius around the wheelset shaft. As a result, the first wheel body has enough free space to arrange, for example, a wheel brake disc on the wheel web.
    It is advantageous if a first toothed ring is arranged on a first end face of the first wheel hub and a second toothed ring is arranged on a second end face of the wheel web.
    This results in a particularly simple assembly and disassembly of the first wheel body. This only has to be placed on the first wheel hub and can thus, already on the first wheel hub and thus secured against falling, be brought into engagement via the second ring gear of the wheel web with the first ring gear arranged on the first end face of the first wheel hub.
    An advantageous embodiment is obtained if the at least one toothing is designed as a flat toothing. This measure results in a particularly good utilization of an existing installation budget. Furthermore, particularly small gaps between individual teeth of the toothing are achieved. As a result, the teeth are well protected against environmental influences and consequently against corrosion. Furthermore, an almost backlash-free transmission of force and torque is achieved between the first wheel hub and the first wheel body.
    A favorable solution is achieved if a secured, central clamping element, which contacts the wheel web, is arranged on a thread of the first wheel hub.
    As a result of this measure, the first wheel hub and the first wheel body are clamped to one another, the clamping element being assembled and disassembled simply and quickly. Furthermore, unintentional loosening or loosening of the tensioning element is avoided.

    201703004
    It is advantageous if a wheel brake disc is connected to the wheel web.
    This measure simplifies and speeds up maintenance and repair processes. For example, the first wheel body can be removed together with the wheel brake disc and replaced by another (e.g. new) first wheel body on which another (e.g. new) wheel brake disc is attached. Disassembly of the wheel brake disc from the wheel web can be dispensed with.
    The invention is explained in more detail below on the basis of exemplary embodiments.
    The following are examples:
    1: a first view of a sectional view of an exemplary embodiment of a wheel according to the invention with a first wheel hub, a first wheel body and a wheel brake disc arranged thereon,
    2: A second view of the exemplary embodiment of a wheel according to the invention according to FIG. 1, and

    A first view of a sectional view shown in FIG. 1 discloses a variant of a wheel according to the invention for a chassis of a rail vehicle.
    The wheel comprises a first wheel hub 1 designed as a short tube with a flange 11 and a first wheel body 2 which has a wheel web 3 and a wheel rim, comprising a wheel flange 4 and a tread 5. The wheel web 3 and the wheel flange 4 are designed as a structural unit. There is no wheel tire that is designed separately from the wheel web 3 and, for example, is connected to it in a positive or non-positive manner.
    The wheel web 3 is arranged on an outer lateral surface 9 of the first wheel hub 1 and contacts the first wheel hub 1 via an inner lateral surface 10. Furthermore, the wheel web 3 contacts the flange 11 of the first wheel hub 1. In the region of the flange 11, the first wheel hub 1 and the wheel web 3 a contact area. A toothing 12 is provided in this contact area, which is shown in more detail in FIG. 2.
    A thread 16 is formed on the outer lateral surface 9 of the first wheel hub 1, onto which a secured clamping element 15 is screwed. The clamping element 15 contacts the wheel web 3 in the region of a third end face 8, braces the first wheel body 2 and the first wheel hub 1 with one another and secures the first wheel body 2 on the first wheel hub 1 against slipping in the direction of a longitudinal axis 24 of the wheel set. The clamping element 15 is formed as a central nut with wedge lock washers, not shown, known from the prior art. The wedge lock washers are arranged between the tensioning element 15 and the wheel web 3 and, due to a wedge effect, generate a clamping force between the tensioning element 15 and the wheel web 3.
    This is an inexpensive solution for screw locking. According to the invention, however, it is also / 24
    201703004 conceivable that the clamping element 15 has multiple screws known from the prior art. When the tensioning element 15 is designed with multiple screws, a plurality of pressure screws are arranged on an annular base surface of the tensioning element 15, the axes of which run parallel to the longitudinal axis 24 of the wheel set. Between the tensioning element 15 and the wheel web 3, a thrust washer is arranged, against which the pressure screws are tensioned and apply pressure forces to secure the tensioning element 15 on the first wheel hub 1.
    According to the invention, other screw locks also known from the prior art are also conceivable. For example, adhesives can be used as integral, lock nuts, clamping nuts or clamping screws as non-positive or split pins, wires, sheets or locking rings as positive screw locks.
    A wheel brake disk 17 known from the prior art is arranged on the wheel web 3 with a first friction ring 18 and a second friction ring 19. A first screw 21 is arranged in a first bore 20, which runs through the wheel web 3, the first friction ring 18 and the second friction ring 19. Further bores are provided which also run through the wheel web 3, the first friction ring 18 and the second friction ring 19 and in which further screws are arranged. The first bore 20 and the further bores are provided on a bolt circle with a defined diameter.
    The wheel brake disc 17 is clamped to the wheel web 3 due to the first screw 21 and the further screws and is thereby secured on the first wheel body 2. According to the invention, it is also conceivable that no brake disc is arranged on the wheel according to the invention or that a block brake acts on the tread 5 of the wheel, etc.
    / 24
    201703004
    The first wheel hub 1 is on a hollow shaft
    Wheelset shaft 23 of the chassis arranged and contacts the outer surface with an inner surface.
    According to the invention, it is also conceivable to design the wheelset shaft 23 as a solid shaft.
    A cylindrical press fit 22 is provided between the first wheel hub 1 and the wheel set shaft 23, as a result of which the first wheel hub 1 is secured against rotation and slipping with respect to the wheel set shaft 23.
    It is a cheap solution. According to the invention, however, it is also conceivable to provide a conical press fit between the first wheel hub 1 and the wheel set shaft 23.
    The first wheel hub 1, the first wheel body 2, the tensioning element 15, the wheel brake disc 17 and the wheel set shaft 23 are arranged concentrically with respect to the longitudinal axis 24 of the wheel set.
    FIG. 2 shows a second view of the sectional illustration disclosed in FIG. 1 of a variant of a wheel according to the invention for a chassis of a rail vehicle. The same reference numerals as in FIG. 1 are used in part in FIG. 2.
    A first wheel body 2 is arranged on a first wheel hub 1, an outer lateral surface 9 of the first wheel hub 1 making contact with an inner lateral surface 10 of the first wheel body 2. The first wheel body 2 is pressed against a flange 11 of the first wheel hub 1 by means of a tensioning element 15 provided on a thread 16 of the first wheel hub 1 and contacting it via a third end face 8, and is thereby secured on the first wheel hub 1 in the direction of a longitudinal axis 24 of the wheel set. A wheel brake disc 17, which comprises a first friction ring 18 and a second friction ring 19, is arranged on a wheel web 3 of the first wheel body 2.
    The first wheel hub 1 is arranged and secured on a wheel set shaft 23 via a cylindrical press fit 22.

    201703004
    In the area of a first end face 6 of the first wheel hub 1 and a second end face 7 of the wheel web 3, the first wheel hub 1 and the first wheel body 2 have a contact area in which a toothing 12 is provided. A first ring gear 13 is arranged on the first end face 6 of the first wheel hub 1 and a second ring gear 14 is arranged on the second end face 7 of the wheel web 3. The first ring gear 13 is in engagement with the second ring gear 14 or the first ring gear 13 and the second ring gear 14 contact each other. The first wheel body 2 is thereby secured against unintentional rotation with respect to the first wheel hub 1 and forces and torques are transmitted between the first wheel hub 1 and the first wheel body 2.
    The toothing 12 is designed as a flat toothing, which is known from the prior art as a spur tooth connection or as a plank serration, or similar to an end spline shaft. As a result, particularly good use is made of an existing installation budget and particularly small gaps between individual teeth, which are V-shaped, of the first ring gear 13 and the second ring gear 14. As a result, the toothing 12 is well protected against environmental influences and consequently against corrosion. Forces and torques are transmitted almost without play between the first wheel hub 1 and the first wheel body 2.
    The toothing 12 is arranged on the end face, which is a cheap solution.
    According to the invention, however, it is also conceivable to arrange the toothing 12 on the circumference, the first ring gear 13 being provided on the outer lateral surface 9 of the first wheel hub 1 and the second ring gear 14 being provided on the inner lateral surface 10 of the wheel web 3.
    The toothing 12 is dimensioned on the basis of a finite element method (FEM) known from the prior art and by means of corresponding calculations. According to the invention / 24
    201703004, however, other design methods that are also known from the prior art are also conceivable.
    The toothing 12 is manufactured on a 5-axis machining center known from the prior art by means of milling. According to the invention, however, other manufacturing means and manufacturing methods also known from the prior art are also conceivable.
    For mounting the first wheel body 2 on the first wheel hub 1, the first wheel body 2 is placed on the first wheel hub 1, so that the outer surface 9 of the first wheel hub 1 contacts the inner surface 10 of the first wheel body 2. As a result, the first wheel body 2 is secured against falling from the first wheel hub 1. The second ring gear 14 of the first wheel body 2 is then brought into engagement with the first ring gear 13 of the first wheel hub 1 in order to secure the first wheel body 2 against unintentional rotation with respect to the first wheel hub 1. The clamping element 15 is then screwed onto the thread 16 of the first wheel hub 1 and pressed against the wheel web 3, i.e. the clamping element 15 is tightened, whereby the first wheel body 2 and the first wheel hub 1 are clamped together.
    For disassembly, the clamping element 15 is released and pulled by the first wheel hub 1. The first wheel body 2 is then pulled by the first wheel hub 1.
    Assembly and disassembly can be carried out easily and with little expenditure of time. For example, to replace the wheel brake disc 17, it is possible to pull the first wheel body 2 together with the wheel brake disc 17 from the first wheel hub 1 and to replace it with another first wheel body 2 with a pre-assembled wheel brake disc 17. According to the invention, however, it is also possible to disassemble or mount the wheel brake disc 17 from the first wheel body 2.

    FIG. 3 shows a top view of an exemplary internally mounted running gear for a rail vehicle with exemplary wheels according to the invention. The undercarriage has a first wheel set 25 with a wheel set shaft 23, a first wheel body 2 and a second wheel body 26 and a second wheel set, not shown, which is structurally identical to the first wheel set 25 and is connected to a chassis frame 29.
    The undercarriage has an internal bearing, i.e. The first wheel set 25 is coupled or rotatably coupled to the chassis frame 29 in a region between the first wheel body 2 and the second wheel body 26 via a first wheel set bearing 27 and a second wheel set bearing 28.
    Following the same principle, the second wheel set is connected to the chassis frame 29 or rotatably mounted via a third wheel set bearing and a fourth wheel set bearing, which are not shown.
    Furthermore, a first primary spring 30, a second primary spring 31 and, not shown, a third primary spring and a fourth primary spring are arranged between the chassis frame 29 and the first wheel set 25 and the chassis frame 29 and the second wheel set.
    A first drive motor gear unit 32 is mounted in the chassis frame 29 and coupled to the first wheel set 25 for the transmission of drive and braking torques.
    A second drive motor gear unit, not shown, is also mounted in the chassis frame 29 and coupled to the second wheel set.
    A first wheel hub 1 is connected to the wheelset shaft 23 via a cylindrical press fit 22. A first wheel body 2 is arranged on the first wheel hub 1 and has a wheel web 3, a wheel flange 4 and a tread 5.
    An outer lateral surface 9 of the first wheel hub 1 contacts an inner lateral surface 10 of the first wheel body 2.
    The first wheel body 2 is against / 24 via a toothing 12, which is also shown in particular in FIG. 2
    201703004
    Twists secured with respect to the first wheel hub 1. The toothing 12 has a first toothed ring 13 arranged on a first end face 6 of a flange 11 of the first wheel hub 1 and a second toothed ring 14 arranged on a second end face 7 of the wheel web 3. The first ring gear 13 is in engagement with the second ring gear 14. Via a clamping element 15 screwed onto a thread 16 of the first wheel hub 1 and contacting the first wheel body 2 via a third end face 8 of the wheel web 3.
    and FIG. 2 is shown, the first wheel body 2 and the first wheel hub 1 are clamped to one another and the first wheel body is secured against slipping in the direction of a longitudinal axis 24 of the wheel set on the first wheel hub 1.
    To remove the first wheel body 2, the clamping element 15 is released and pulled off the first wheel hub 1. The first wheel body 2 is then pulled off. Disassembly and assembly of the first wheel body 2 can be carried out easily and quickly from the outside of the chassis. It is not necessary to remove the first wheel set 25 from the undercarriage or to separate the first wheel set 25 from the undercarriage frame 29.
    The second wheel body 26 of the first wheel set 25 is designed in the same way as the first wheel body 2 with regard to constructional and connection principles.
    According to the invention, it is also conceivable, for example, that the undercarriage has an external bearing (ie the wheelset shaft 23 is connected to the undercarriage frame 29 via a bearing outside of an area between the wheels), as a non-powered undercarriage or as a loose wheel undercarriage, as is known, for example, for low-floor vehicles is. Furthermore, it is also conceivable that the chassis has only one or more than two wheel sets.
