Definitions

  • the invention relates to a so-called parallel shaft drive unit for rail vehicles according to the preamble of the main claim. It is based on a state of the art, e.g. known from U.S. Patent No. 3,152,558.
  • the screwed housing of the motor and transmission are supported vertically at one point and horizontally on the bogie frame via a transverse stabilizer, in each case with interposed rubber washers.
  • the third support point is an elastic coupling between the hollow shaft of the gearbox and the axle set.
  • This coupling essentially consists of two rubber washers between three flange washers, the first of which is or are connected to the axle of the wheelset, the other two to the hollow shaft.
  • the clutch not only has to transmit the torque from the engine-gearbox assembly to the axle of the wheelset, but also has to bear a considerable proportion of both the engine reaction torque and the weight of the engine-gearbox assembly.
  • the rubber is predominantly subjected to thrust by the weight and the inertial forces occurring during driving operation, in a plane perpendicular to the axle of the wheelset.
  • the rubber washer In order not to let the drive unit sag too much with respect to the axle of the wheelset, the rubber washer must be relatively narrow and hard. However, this increases the negative effects of the shear stress and further worsens the spring action in the transverse direction, i.e. in the direction of the axle of the wheelset. (Another, The main disadvantage is that if the rubber washers have to be replaced, the wheels have to be pulled off the axles.)
  • the suspension of the drive unit according to the US patent is only a 2-point suspension with a cross stabilizer. Since the latter should not only absorb the forces and movements mentioned above while driving, but also must secure the motor-gear unit against tipping in the rest position, the rubber disks mentioned must not be particularly soft. As a result, however, they are again not very suitable for absorbing the movements originating from the axle of the wheelset.
  • a motor-transmission unit is also known (EP 0010-619 B1), in which the screwed housing of the motor and transmission are rigidly attached to the bogie frame.
  • a complex clutch unit is provided, in which the gearbox hollow shaft is connected to the wheelset axle via a first clutch, a cardan hollow shaft and a second clutch. Since the relative movements between the gearbox hollow shaft and the wheelset axis are considerable, a corresponding free space must be provided which adversely affects the dimensions of the gearbox hollow shaft and its bearings and thus the size of the gearbox housing. Such a drive unit can therefore hardly be used for low-floor vehicles.
  • the invention is therefore based on the object of developing a drive unit of the type mentioned in such a way that, with the greatest possible comfort in terms of suspension and shock absorption, its space requirement is as small as possible and it can therefore also be used in vehicles of the low-floor type.
  • a drive unit which has the characteristics of claim 1.
  • This design allows the diameter of the gearbox hollow shaft to be reduced, which allows the use of smaller bearings and thus a smaller housing.
  • Star, articulated or the like couplings effective in three planes, which permit an angular offset, are known from other applications in rail vehicles. You can compensate for all relative movements between the wheelset axle and the engine-gearbox unit. (The specification "simple” does not represent a synonym for "primitive” or the like, but indicates the structural difference from the "double” articulated coupling used in EP 0 010 619 B1.)
  • the two essentially vertically acting support points need except part of the weight forces and the motor reaction torque to absorb only small transverse forces resulting from driving. All other forces, moments and movements are absorbed and transmitted by the - actually - elastic coupling.
  • the prior art cannot offer any suggestion for this solution.
  • a 3-point support of a drive unit of the type mentioned is also described in DE 24 34 420 B2.
  • the motor-gear unit is supported on three elastic links in the frame of the rail vehicle, which comes close to a rigid attachment.
  • a cardan coupling between the gearbox hollow shaft and the wheelset axle is required, which is used exclusively for torque transmission.
  • an expedient embodiment is shown in claim 2.
  • an embodiment according to claim 3 is useful.
  • an off-center arrangement of the elastic coupling or its arrangement on the side of the transmission facing away from the engine would have been more expedient with regard to the weight distribution or the forces to be absorbed by the transverse stabilizer.
  • a brake disc In the known parallel shaft drives, a brake disc is often attached to the axle of the wheelset.
  • the associated brake shoes and their actuation mechanism are arranged on the bogie frame.
  • the change in position of the brake disc relative to the brake shoes due to the relative movements between the axle of the bogie and the bogie frame requires complex structural measures to ensure a reliable effect of the brake.
  • the brake arrangement can be simplified considerably, since the brake disc and brake shoes always remain in the same position relative to one another.
  • a single-stage gearbox can also be used with the appropriate gear ratio.
  • the hollow shaft (13) like the shaft (12) (and possibly the pinion 8), can be rotated with roller bearings (not shown) but cannot be moved axially in the housing (14) of the transmission (5) and protrudes on one side the housing (14) out.
  • the wheelset axis (3) is guided approximately centrally, on which the drive wheels (15, 16) are mounted in a rotationally fixed manner.
  • a first flange (18) is fixedly connected to the hollow shaft. and a second flange (19) is fixedly connected to the axle of the wheel set, and an intermediate member (20) which is not supported is provided between them.
  • the first flange (18) is articulated to the intermediate link (20) via the control arm (21) and the second flange (19) via the control arm (22).
  • bolts (23) are fastened to the flanges (18, 19) and to the intermediate link (20), on which the handlebar levers (21, 22) are mounted by means of known and therefore not shown elastic members, so-called rubber joints.
  • a four-link chain is formed from the first flange (18), the link arms (21) and the intermediate link (20), and a further four-link chain is formed from the intermediate link (20), the link levers (22) and the second flange (19). Since the intermediate link (20) connecting the two four-link chains is not supported, the coupling can compensate for the radial movements between the sprung parts (positions 4, 5, 18) and the unsprung parts (positions 3, 15, 16, 19).
  • the articulated coupling (17) also serves to support the motor-gear unit (6) on the axle set (3). It is expedient if the articulated coupling (17) is at least approximately in the middle between the driving wheels (15, 16), i.e. in the longitudinal axis (24) of the vehicle, because then when driving over bumps in the track, switches, etc., there is no one-sided load on the axle set (3) are exerted on the articulated coupling, which in turn cause restoring forces.
  • Two additional support points (25, 26) are provided for supporting mass acceleration forces and tilting moments.
  • the motor (4) and / or the gear housing (14) is elastically supported on the bogie frame (2) or suspended by means of a vertical control arm (not shown).
  • the brake disc (28) of a disc brake (27) is also arranged on the axle (3) between the articulated coupling (17) and the adjacent drive wheel (15).
  • the actuating device with the brake shoe (29) are attached to the bogie frame (2).
  • a star coupling (30) is shown in FIG. 2 as an example for another coupling.
  • a first coupling half (31) is fixedly connected to the hollow shaft (13).
  • a second coupling half (32) is fixed in a rotationally fixed manner on the axle set (3).
  • Both coupling halves (31, 32) have radially outwardly directed arms which are alternately one behind the other in the circumferential direction. Rubber blocks (not shown) are arranged between two arms, which bear against the arms under prestress.
