Definitions

  • the invention relates to a hollow shaft drive for two drive axles of a chassis for a rail vehicle according to the preamble of claim 1.
  • Such a hollow shaft drive is known from DE-C-25 14 265 and is particularly compact and lightweight due to its housingless motor design with the omission of separate end shields.
  • a traction-ventilated three-phase motor with a short-circuit rotor is usually provided as the traction motor, which has a fan seated on the motor shaft, which is arranged in a correspondingly designed fan chamber section next to a pressure ring lying on the end faces of the clamped stator core package.
  • the two fan chamber sections of the gear housing have circumferential air outlets for the cooling air flowing through the drive motor.
  • the gear housing is supported with its gear housing heads on the hollow shafts surrounding the drive axles for the drive wheels, which in turn are mechanically connected to the drive axles in a known manner.
  • the stator core package protrudes radially on all sides over the slimmer gear housing necks and must have a minimum safety distance from the track surface.
  • the air outlets are protected against the ingress of foreign bodies into the engine interior by air covers that cover the air outlets on all sides by a distance.
  • the outer surfaces of the stator core and the gearbox housing are exposed to the cooling driving wind, so that sufficient cooling of the driving motor and the gearbox is always guaranteed even with higher engine loads.
  • such hollow shaft drives produce ranges in particular at acceleration and braking, i.e. Speed ranges, disturbing noises that are perceived as particularly annoying when driving in inhabited areas.
  • Speed ranges disturbing noises that are perceived as particularly annoying when driving in inhabited areas.
  • Measurements have shown that the tonal, torque-dependent noises occurring when starting off or braking have an increasing and decreasing tone frequency with the engine speed, i.e. the frequency of the dominating magnetic sound changes proportionally with the operating frequency or the driving speed and runs through the natural frequency of different parts of the hollow shaft drive. This results in an airborne sound resonance of approx. 640 Hz due to the natural frequency of the stator core, which is followed by several briefly very loud resonances in the frequency range from approx.
  • the invention has for its object to reduce such annoying noises, without noticeable impairment of the heat dissipation and in compliance with the said minimum distance of the drive to the track surface and the required maintenance accessibility of the auxiliary devices with easy assembly and disassembly of the measures necessary for noise reduction without constructive intervention in the hollow shaft drive, so that retrofitting of hollow shaft drives with noise-reducing devices is possible without constructive intervention in the hollow shaft drives and their storage.
  • noise reduction capsules made of sound-reducing material for drives of road vehicles, consisting of fan-cooled internal combustion engines including a manual transmission, which have openings for the noise reduction capsule on the front and rear sides have cooling air flowing through them, which is arranged inside the noise-reducing capsule, wherein the openings are assigned sound-absorbing means.
  • the noise reduction capsule is connected to vehicle parts, but not to the drive itself, so that relative movements between the flexible drive mounted in the chassis and the noise reduction capsule must be taken into account by correspondingly larger distances between the drive and the noise reduction capsule in order to prevent an undesired one-sided narrowing of the cooling air paths or a sound-transmitting contact to avoid the drive, which further increases the dimensions of the noise reduction capsule.
  • a track vehicle with its structure, not shown, is mounted on chassis, via conventional turntables, also not shown, one of which is provided with a hollow shaft drive shown.
  • Each hollow shaft drive contains a housing-free drive motor 1, the stator core 1A of octagonal contour is provided on both ends with pressure rings 2, which are pressed in a known manner, not shown, by clamps arranged on the circumference against the stator core 1A and hold it together.
  • pressure rings 2 With the pressure rings 2 gear housing 3 are releasably connected, in which the motor shaft and the gear shafts are mounted, so that separate end shields are omitted.
  • Each gear housing 3 has a fan chamber section 3A adjoining the associated pressure ring 2, a slimmer gear housing neck 3B and an end-side gear housing head 3C, which is supported on a hollow shaft 4 coupled to the gear, which surrounds a drive axle 5 for drive wheels 6 and with it is not mechanically coupled known manner not shown.
  • Each transmission housing 3 has in the area of the fan chamber section 3A air passages 3D for the cooling air flowing through the engine interior.
  • a fan is attached to the motor shaft and conveys the cooling air through the motor interior.
  • housing parts 8, 9 project laterally for auxiliary devices (brake pressure cylinders, cables, etc.) which can be influenced from the outside and which must be accessible from the outside and seal the interior of the engine and transmission from the outside.
  • auxiliary devices brake pressure cylinders, cables, etc.
  • the area from the gear housing neck 3B to the gear housing neck 3B is encased by an axially divided sound reduction capsule 10, which consists of deadened top, side and bottom surfaces 10A, 10B, 10C and has the sound damping means 11, 12, 13 in a special arrangement and design, such as this is explained in more detail below.
  • an axially divided sound reduction capsule 10 which consists of deadened top, side and bottom surfaces 10A, 10B, 10C and has the sound damping means 11, 12, 13 in a special arrangement and design, such as this is explained in more detail below.
  • the noise reduction capsule consists of deadened sheets, i.e. H. Sheets made of iron, aluminum or other metal coated with structure-borne noise-suppressing anti-drumming material, in which the relatively thin-walled sheets are provided with a less than three times thicker anti-drumming layer, so that the sound waves emanating from the interior of the noise-reducing capsule are reflected at a location other than the place of immission. Since there is no energy conversion during sound insulation, a sound congestion occurs in the free interior of the sound reduction capsule 10, the sound interference or standing sound waves of which would cause an increase in the sound level if no sound damping means 11, 12, 13 were provided at special inner locations of the sound reduction capsule.
  • the side surfaces 10B and the top surface 10A are coated with sound damping means 11, 12 which are adapted to the wavelength of the most disturbing magnetic tones in such a way that, despite the need to maintain a sufficient distance from the top edge of the track OS when one is released Air duct 14 between the two transmission housings 3 and the floor surface 10C, which has only been removed, a strong reduction in noise occurs.
  • the sound reduction capsule 10 has in the axial direction at the parting line 15 divided side surfaces 10B, the lower sections of which form a unit with the bottom surface 10C and whose upper sections form a unit with the top surface 10A, in such a way that the lower part of the sound reduction capsule 10 is removable.
  • Recesses in the sections of the two side surfaces 10B enclose the projecting housing parts 8, 9 already mentioned.
  • the upper part of the noise reduction capsule 10 is supported by structure-borne sound insulation at 18, 19 on the pressure rings 2 and the gear housing 3 in the area of the air passages 3D.
  • the gear housing necks 3B are provided at a distance 20 around the open end faces of the air-reducing capsule 10, each with a divided sound-absorbing wall 13, which are tightly connected to the bottom surface 10C and the side surfaces 10B, but have a free space 16 to the top surface 10A.
  • the stator core package 1A is surrounded by the sound damping means 11, 12 of the top and side surfaces 10A, 10B except for four corner-side clearances 17, which form two axial air ducts in the area of the octagonal stator core contour and a further duct 14 between the bottom surface 10C and the stator core package 1A to avoid heat build-up in the traction motor 1.
  • the wall thickness of the individual sound damping means 11, 12, 13 is dimensioned both for the sufficient sound damping and for sufficient cooling air delivery through and around the drive motor 1.
  • the noise reduction capsule 10 can take over the securing function of the air covers which form undesirably noises, wherein the air passages 3D in the gearbox housings 3B can be additionally secured by noiseless plastic grids 7.
  • additional front-end noise-damping aprons can be provided in front of the structure-borne sound insulation in a manner not shown.
  • the soundproofing means can preferably consist of stone and glass fiber material, in particular in the form of solid, plate-shaped coverings.
