Definitions

  • the invention relates to an electromotive direct drive for vehicle wheels.
  • Such a direct drive is known from DE-A-38 17 537.
  • Direct drive usually means, and in the present application, those drives in which the electric motor is spatially closely assigned to a wheel to be driven without the interposition of a transmission.
  • the torque transmission connection of the rotor of the electric motor to the wheel to be driven is made either to the wheel to be driven itself or to an axle shaft on which the wheel to be driven sits in a rotationally fixed manner.
  • Electromotive direct drives are sometimes also referred to as axis motors.
  • Equipping vehicles in particular rail vehicles, with at least one axle motor, on the one hand, appears to be an attractive option because transmissions, right-angled deflections of the torque flow or the like can be saved, so that one can hope to achieve cost advantages and space advantages.
  • axis motors assuming the same torque, are larger and heavier due to the omission of a gear.
  • Asynchronous motors have been installed as axis motors for experimental purposes. These attempts have not led to results that can be used from an economic point of view because the achievable engine torque was too low or the engines were too large in terms of mass and volume.
  • the invention is based on the object of making a comparatively light and space-saving direct drive available which, however, delivers a comparatively high torque, measured in terms of the installation volume required and the weight.
  • An electronically commutated electric motor with external rotor and without housing is provided.
  • the essentially cylindrical air gap surface is at an optimally large diameter.
  • the proposed motor is optimally used due to the construction with permanent magnets and due to the electronic commutation in terms of volume, mass and processable current. All this together leads to an optimally high, deliverable torque - measured in terms of volume and mass.
  • the rotor In order to increase the compactness or the torque of the electric motor, the rotor is designed from the point of view of the flux concentration, the magnetic flux density being greater at the pole faces of the rotor on the air gap than at the end faces of the permanent magnets.
  • Electronically commutated electric motors are known per se, so that no further details need to be described in this regard. Electronically commutated electric motors can best be compared to DC motors in terms of their design system.
  • a rotation position sensor often a Hall sensor, detects the current rotation position of the rotor and, based on signals from the rotation position sensor, electrical voltage is applied to the stator windings or stator coils with the correct time and sign.
  • the direct drive according to the invention is particularly preferred for high-speed rail vehicles, because high wheel speeds occur at these, that is to say high drive powers are available for a given torque of the drive motor, and because the aspect of a large starting acceleration capacity is not in the foreground.
  • High-speed rail vehicles are considered to have a top speed in the range of 200 to 300 km / h, or even higher.
  • the rotor is preferably constructed with highly coercive permanent magnets or permanent magnets with a high energy product.
  • Permanent magnets of this type are known, in particular from rare earth cobalt material or iron neodymium material.
  • the rare earth material component can consist of one or more rare earth elements, in particular samarium.
  • Highly coercive permanent magnets or permanent magnets with a high energy product deliver a high permanent magnet excitation, allow a high motor EMF with comparatively low inductance, allow a particularly compact structure of the rotor, and allow the con Structure of the engine with a comparatively large, radial air gap width, which is favorable for reasons that will be discussed below.
  • the connecting device can be a type of flexible coupling.
  • the connecting device is preferably resilient and / or damping. The main advantage of the named connecting device is that the shock maxima of the wheel are kept away from the rotor. This applies even if the rotor is supported by means of the bearing of the wheel or the axle shaft of the wheel.
  • the rotor is supported by its own bearing, which enables primary wheel suspension without primary rotor suspension and stronger decoupling of the wheel joints from the rotor.
  • the variant is possible that the entire electric motor, i.e. stator and rotor, is supported and / or damped on the vehicle, for example the wheels, their axles or axle shafts and their electric motors making up the unsprung vehicle masses.
  • the wheel to be driven is connected to the vehicle with the interposition of a primary suspension arranged as early as possible in the shock transmission chain.
  • the "earliest" or closest to the wheel of the primary suspension is a primary suspension between the actual wheel and its stationary wheel axle or its rotating axle shaft.
  • the “two earliest” or second closest location of the primary suspension to the wheel is between the stationary wheel axle or the co-rotating wheel axle shaft and the vehicle. It is pointed out that in both cases the rotor of the electric motor can either belong to the mass unsprung by the primary suspension (wheel or wheel axle or axle shaft) or to the mass sprung by the primary suspension in the shock transmission chain behind the primary suspension.
  • a brake disc can be rigidly assigned to the wheel to be driven on at least one axial side. On the axial side opposite the electric motor, there is normally enough space for such a brake disc.
  • a brake disk rigidly assigned to the wheel can be provided between the electric motor and the wheel to be driven.
  • rigidly assign a brake disc to the rotor of the electric motor. This often offers spatial advantages.
  • the brake disc can also be assigned to the sprung mass which is arranged downstream of the primary suspension.
  • the electric motor provided according to the invention - measured by its torque - is so small that it can often be arranged on the outside of the wheel to be driven, in particular still within the vehicle limit prescribed for railway vehicles.
  • Fig. 1 shows a part of a rail vehicle 2, for example a rail car for passenger transportation, wherein a rail wheel 4 to be driven on a vehicle side, its axle motor 6, a part of the chassis 8 of the vehicle 2 supporting the wheel 4 and the motor 6, and a lower part of the vehicle body or the vehicle body 10 for receiving the payload or the persons to be transported.
  • the chassis 8 can, for example, be one of two bogies on which the vehicle body 10 rests. But it can also be a chassis 8, which is non-rotatably connected to the vehicle body 10.
  • a suspension (not shown) and possibly damping can be provided between the wheel 4 and the chassis 8 and / or between the chassis 8 and the vehicle body 10.
  • the wheel 4 is rigidly attached to an axle shaft 12.
  • a brake disk 14 is rigidly attached axially to the left and right of the wheel on the axle shaft 12.
  • the axle shaft 12 is rotatably mounted in the chassis 8 by means of roller bearings 16.
  • the axle shaft 12 is elongated and provided with a flange-like end region 18 of larger diameter.

  • the connecting ring 22 sits on the axial side of the end region 18 facing the wheel, and the end wall of the rotor 20 projects radially inwards there the connecting ring 22.
  • the axle motor 6 is located in FIG. 1 to the right of the wheel, that is to say on the outside of the vehicle, from the wheel 4.
  • the chassis 8 in FIG. 1 has an extension 24 projecting downward to the right of the rotor 20.
  • a circular mounting flange 26 is attached on the inside of this extension 24, a circular mounting flange 26 is attached.
  • the fastening flange 26 carries an inwardly projecting, strong, tubular support 28.
  • Stator poles 30 made of ferromagnetic material with windings 32 are attached in an annular distribution to the outer circumference of the support 28.
  • the rotor 20 has permanent magnets distributed in a ring, which are not shown in FIG. 1 for the sake of clarity.
  • the pole pitch of the permanent magnets is matched to the pole pitch of the stator poles 30, so that an electric motor with permanent magnetic excitation is formed by the stator constructed with the stator poles 30 and the permanent magnets attached to the rotor 20.
  • the permanent magnets are arranged with alternating polarity along the rotor circumference.
  • a support column 34 can be seen above the wheel 4.
  • the actuators of the motor 6 are controlled by means of a rotational position sensor (not shown) of the motor 6 in such a way that they supply electrical current to the individual windings 32 of the stator poles 30 with the correct time and sign.
  • a channel 38 in which power cables and cooling lines run, leads from the installation space 36 to the extension 24 and through the extension 24 into the interior of the support 28.
  • Line 39 indicates the outer contour of the vehicle, which is 2950 mm wide for the German Federal Railroad, for example.
  • Line 40 indicates the narrowest permissible guideway limitation, i.e. the limit up to which outer guideway parts, such as tunnel walls, masts and the like, may be arranged as close as possible to the rails of the guideway.
  • vehicle limitation 11 of the railway operating regulations of the Deutsche Bundesbahn.
  • the axle motor 6 is located within the vehicle contour 39 and within the boundary 40.
  • the so-called Lemniscate handlebar for setting the drive is indicated at 42.
  • the drawing must be supplemented to the left in a mirror-image manner, supplemented by a central vehicle part and supplemented by an upper vehicle area, so that the entire vehicle 2 can be seen in cross section.
  • a cooling air outlet is indicated at 44.
  • the vehicle body 10 as a low-floor vehicle, extends deeper than the upper area of the circumference of the wheel 4.
  • the corresponding wheel 4 on the other side of the vehicle is also provided with an axle motor 6.

  • the wheel 4 could be rotatably mounted on the axle 12.
  • the right support of the axle 12 would then have to take place, for example, on the extension 24 of the chassis 8.
  • the resilient and resilient connecting ring 22 leads to impacts, in particular impact maxima, being passed on to the rotor 20 in a reduced manner.
  • FIG. 3 shows a variant in which the rotor 20 is mounted in the support 28.
