Description

The present invention relates to a chassis unit for a vehicle, in particular a rail vehicle, with a motor holding device, in particular a chassis frame, and a connectable to the motor holding device attachment means for a traction motor unit, wherein the motor holding device a longitudinal direction, a transverse direction, a height direction and in the height direction an upper side and a bottom defined. The motor holding device is designed to be supported on at least one wheel unit to be driven by the traction motor unit in the height direction. The fastening device is designed for substantially rigid support of the traction motor unit on the motor holding device in the height direction via at least one positive connection. The fastening device is furthermore configured in such a way that the traction motor unit can be inserted into the motor holding device on a mounting path, in particular from the underside of the motor holding device, for mounting the traction motor unit, wherein the fastening device has at least one fastening element which can be brought into engagement with the motor holding device and the traction motor unit having. The invention further relates to a corresponding vehicle, in particular a rail vehicle, with a chassis unit according to the invention and a corresponding method for mounting a drive motor unit on a chassis unit.

Such a design is often applied to bogies of rail vehicles their application to attach a traction motor to the bogie frame. This is how, for example, from the JP 62016036 A is known, often mounted at least one (in the upper part of the engine mounted) upper support arm with a downwardly facing recess (in the height direction from above) in an upwardly facing projection on the bogie frame to hold the engine by positive locking captive on the bogie frame. Subsequently, the motor is still connected via simple screw (including in the field of positive connection) frictionally connected to the bogie frame to achieve a vibration-proof connection.

In order to easily remove the engine, for example, for maintenance or repair, it is usually desirable to be able to take it down from the bogie without having to make further intervention on the rail vehicle (in particular without removing the bogie from the vehicle have to).

The mounting of the motor from above into the bogie frame, however, has the disadvantage that the motor during assembly or disassembly by a considerable transverse travel (transverse to the height direction) must be moved to the arm of the engine (in the height direction from below) to be able to lead past the projection on the bogie frame, in which it should then be suspended (from above). For this is in modern bogies due to the large number of components housed there usually only very little space available, so to be kept free for the assembly and disassembly of the motor along the mounting path space (mounting channel) on the one hand further aggravates the space problem. In addition, it is disadvantageous that this space to be kept free for the assembly or disassembly of the engine is required in large parts only during the assembly or disassembly of the engine, while it is unused at other times.

The present invention is therefore based on the object to provide a suspension unit or a mounting method of the type mentioned which or which does not have the disadvantages mentioned above or at least to a lesser extent and in particular with a simple design a simple installation of the drive motor unit in a confined space.

The present invention solves this problem starting from a chassis unit according to the preamble of claim 1 by the features stated in the characterizing part of claim 1. It solves this problem further starting from a method according to the preamble of claim 15 by the features stated in the characterizing part of claim 15.

The present invention is based on the technical teaching that, with a simple design, a simple installation of the traction motor unit in a confined space allows, if at least one fastening element is used for the fixation or support of the drive motor unit with the motor holding device and the traction motor unit each via a Positive locking cooperates and is used in a direction transverse to the mounting direction locking direction between the motor holding device and the traction motor unit only when it is already in the region of its support position.

In other words, in the assembled state, the fastening element can in this case form the projection on the motor holding device, in which the traction motor unit is mounted (positively locking) in order to achieve a captive fixation of the motor as in the known designs. On the other hand, in the assembled state, the fastening element forming the projection on the motor holding device during the movement of the Driving motor unit in the region of its support position (unlike the known designs) be removed from the movement space of the drive motor unit, so that the traction motor unit moves by the shortest route and at least without major evasive movements (eg around the projection on the motor holder) in its supporting position can be.

For assembly or disassembly of the traction motor unit, only a minimal (predetermined by the dimensions of the traction motor unit) mounting channel is therefore to be kept free along its mounting path, whereby the installation space problem in the suspension unit defused. In addition, due to the at least largely avoiding evasive movements during assembly or disassembly of the drive motor unit, the complexity of the assembly movement is reduced, so that the assembly and disassembly are correspondingly simplified. In the simplest case, only a single linear movement can be sufficient.

According to one aspect of the invention, therefore, this relates to a chassis unit for a vehicle, in particular a rail vehicle, with a motor holding device, in particular a chassis frame, and a connectable to the motor holding device attachment means for a traction motor unit, wherein the motor holding device a longitudinal direction, a transverse direction, a height direction and in the height direction defines a top and a bottom. The motor holding device is designed to be supported on at least one wheel unit to be driven by the traction motor unit in the height direction. The fastening device is designed for substantially rigid support of the traction motor unit to the motor holding device in the height direction via at least one positive connection, wherein the fastening device is designed such that the traction motor unit for mounting the traction motor unit to the motor holding device on a mounting path, in particular from the bottom of the motor holding device forth , is used in the motor holding device. The fastening device has at least one fastening element that can be brought into engagement with the motor holding device and the traction motor unit, wherein the fastening element is movable into a locking position in a traction motor unit located in the region of the supporting position in a locking direction extending transversely to the mounting direction. In addition, in the locking position for supporting the traction motor unit in the height direction, the fastening element cooperates with the motor holding device via a first positive locking acting in the height direction and with the traction motor unit via a second positive locking acting in the height direction.

It may be provided that the fastening element supports the traction motor unit via the first and second positive locking essentially exclusively in the vertical direction. For this purpose, for example, flat, perpendicular to the vertical direction stop surfaces may be provided on the fastening element and the traction motor unit and the motor holding device for forming the first or second positive locking. The support of the traction motor unit in other directions can then be ensured by any other suitable means (such as screw etc.).

In preferred variants of the invention with a reduced number of additional fastening or securing elements, the height direction is a first supporting direction and the fastening element is formed in the locking position for supporting the traction motor unit in a second supporting direction extending transversely to the first supporting direction, the second supporting direction in particular transversely to the Locking direction runs. In this case, it can be provided that the fastening element interacts with the motor holding device via a third positive connection acting in the second supporting direction. Likewise, it can be provided that the fastening element interacts with the traction motor unit via a fourth positive engagement acting in the second supporting direction.

The first positive connection and the second positive connection can be realized in any desired manner, for example via the already mentioned planar contact or stop surfaces, which only realize a form fit in one direction. Preferably, the first positive locking and / or the second positive locking is realized via at least one projection on a component of the chassis unit, which engages in at least one associated recess in another component of the chassis unit. This ensures in an advantageous manner that the respective form-fitting acts in several directions.

In this case, for example, it may be provided that a recess is provided on the motor holding device, while the associated projection is arranged on the fastening element (or vice versa). Likewise, a recess may be provided on the traction motor unit, while the associated projection is arranged on the fastening element (or vice versa).

The recess can be designed in any way that allows mounting of the fastener in the locked position. Thus, the recess may be designed, for example, as a simple through-hole or blind hole of the fastening element, wherein it has a has any suitable cross section (circular, curved in sections and / or sections polygonal etc.). Preferably, the recess is formed in the manner of a groove, since this is a particularly simple production and subsequent assembly of the fastener is possible.

In preferred variants of the invention with particularly simple production and subsequent assembly of the fastening element, the fastening element for producing the first positive connection has a first recess and for producing the second positive connection a second recess, wherein the fastening element then preferably substantially S-shaped with first remote from each other Recess and second recess is formed.

The contact region between the fastening element and the traction motor unit or the motor holding device can be designed such that it essentially applies only the supporting force in the vertical direction via the positive locking. Preferably, a contact region between the fastening element and the traction motor unit and / or a contact region between the fastening element and the motor holding device is designed such that it is designed to receive a torque resulting from the weight force of the traction motor unit. Hereby, an improved support or a reduction of the components required for this purpose is achieved in a simple manner. Preferably, the region forming the first positive connection and / or the region forming the second positive connection are already designed to receive a moment resulting from the weight force of the traction motor unit, so that these regions advantageously both the function of the support in the height direction and the support of such Integrate moments.

The assembly path of the drive motor unit can basically have any desired course. Of course, the mounting path is of course designed to be as straight as possible in order to minimize the complexity of the movement of the traction motor unit during assembly or disassembly. Preferably, the mounting path defines a mounting direction that at least partially extends in the height direction in the limited mobility mounting portions in which components of the traction motor unit adjoin other components of the suspension unit in a manner restricting the free mobility of the traction motor unit. Preferably, the mounting direction is less than 30 °, preferably less than 15 °, more preferably less than 5 °, inclined to the height direction in order to perform the simplest possible lifting movement during assembly / disassembly can.

The drive motor unit can basically perform any complex movement along its mounting path during assembly / disassembly, which may be due to the adjacent internals. Preferably, however, a possible rectilinear mounting path is provided in order to reduce the complexity of the movement and thus simplify the assembly. In particularly favorable variants of the present invention it is therefore provided that an envelope of the traction motor unit defined by the assembly movement of the traction motor unit defines a minimum required mounting channel with a center line during assembly of the traction motor unit in the limited mobility mounting sections, the center line having a starting point upon entry into the agility limited Assembly sections defined and defines an end point in the support position. The measured distance in a distance direction of the center line of a connecting line between the starting point the end point is then less than 15%, preferably less than 5%, more preferably less than 2%, the dimension of the traction motor unit in the distance direction is at least one as far as possible going approaching to achieve a straight-line course.

The fastener itself may already be designed so that it can absorb the torque resulting from the weight of the drive motor unit. Preferably, however, it is provided that the fastening element is arranged in the support position of the drive motor unit in a first support portion and the drive motor unit, the motor holding device for receiving resulting from the weight of the drive motor unit moments in at least one of the first support portion spaced second support portion directly or via at least one support element contacted. This makes a particularly simple design of the fastener possible.

The fastening element can in principle be designed and / or arranged such that it is held in its locking position during operation of the chassis unit by the forces resulting from the weight force of the traction motor unit. Preferably, however, a securing device is provided, which secures the fastening element in the supporting position, in particular along the locking direction, against displacement from its position. This safety device can be attached to any position on the chassis unit. Preferably, the securing device is releasably connected to the motor holding device. The securing device may be designed in any suitable manner. For example, simple screws or the like may be provided for this purpose. Furthermore, the securing device can at least one securing element, in particular in the form a securing plate, which ensures the securing of the fastening element in its locking position.

In preferred variants of the chassis unit according to the invention, the connection between the fastening element and the motor holding device in the region of the first positive connection is formed selbstzentrierend. For this purpose, it may comprise an at least partially wedge-shaped recess in a particularly simple variant. The same applies additionally or alternatively for the connection between the fastening element and the drive motor unit in the region of the second positive connection.

The movement of the fastener in its locking position can be done in any suitable manner. In a particularly easy-to-implement variant of the invention, the fastening element is designed as a separate, freely movable into the locking position element. Alternatively, the fastener may be pivotally coupled to the traction motor unit and / or the motor retainer, thereby facilitating handling of the fastener upon movement to the lock position. The same applies to variants in which the fastening element is displaceably mounted on the traction motor unit and / or the motor holding device.

It is understood that, where appropriate, a single appropriately designed fastener can be sufficient. In preferred variants of the chassis unit according to the invention, however, a plurality of fastening elements is provided, wherein the fastening elements are spaced in their locking position, in particular in the locking direction. As a result, on the one hand reduces the effort for the individual fastener. On the other hand, there is greater scope for the arrangement of the individual fastener given the space restrictions in the chassis.

The invention can be used particularly advantageously in connection with bogies having a bogie frame as a motor holding device. In this case, their advantages come into play especially when the bogie has two wheel units, which can each be driven by an associated, attached to the bogie frame drive motor unit.

The present invention further relates to a vehicle, in particular a rail vehicle, with a car body and the vehicle body supporting the vehicle body according to the invention. This makes it possible to realize the variants and advantages described above to the same extent, so that reference is made here only to the above statements.

The present invention further relates to a method for mounting a traction motor unit to a chassis unit of a vehicle, in particular a rail vehicle, wherein the traction motor unit is used for mounting on a motor holding device of the chassis unit on a mounting path in the motor holding device and brought to a support position and the traction motor unit means a fastening device is attached to the motor holding device such that the traction motor unit is substantially rigidly supported on the motor holding device in a height direction via at least one positive connection.

First embodiment

The 1 to 4 show schematic views of parts of a vehicle according to the invention in the form of a rail vehicle 101 comprising a car body (not shown) mounted on a chassis unit in the form of a bogie 102 is supported. The bogie 102 includes a bogie frame 103 to which a traction motor unit 104 is attached so that the bogie frame 103 Consequently, therefore forms a motor holding device according to the present invention.

For easier understanding of the following explanations, a chassis coordinate system x, y, z is indicated in the figures (that in the plane even track with the coordinate system of the vehicle 102 coincides). In this coordinate system, the x-coordinate denotes the longitudinal direction of the bogie frame, the y-coordinate the transverse direction of the bogie frame 103 and the z-coordinate the height direction of the bogie frame 103 ,

The bogie frame 103 is supported in the height direction (z-direction) on two wheel units (not shown) in the form of wheelsets, each of a drive motor unit 104 are driven. The drive motor unit 104 is in her in the 1 and 2 two illustrated support position via a fastening device 105 essentially rigid to the bogie frame 103 attached and thus supported in the height direction (z-direction).

For this purpose, the fastening device comprises 105 four fasteners 106 that are in the in the 1 and 2 States shown in a locking position in which they on the one hand each with a first attachment portion 103.1 of the bogie frame 103 and on the other hand with a second attachment portion 104.1 the traction motor unit 104 be in positive engagement, as described below with reference to one of the fastener 106 is described.

Such is the one on the first attachment portion 103.1 a first advantage 103.2 formed in an at least partially complementary first recess in the form of a first groove 105.1 in the fastener 106 intervenes. On the other hand is on the drive motor unit 104 a second advantage 104.2 formed in an at least partially complementary second recess in the form of a second groove 106.2 intervenes.

The first attachment section 103.1 is realized in the present example by a corresponding molding, which on the bogie frame 103 is attached, for example, is welded. However, it is understood that in other variants of the invention can also be provided that the first mounting portion is monolithically formed with the bogie frame. Likewise, any releasable connection may be provided with the bogie frame.

The second projection 104.2 is formed by a pin-like projection extending in the transverse direction (y-direction) at the free end of a fastening tab extending in the longitudinal direction (x-direction) 104.3 the traction motor unit 104 is arranged.

Again 1 it can be seen in the present example in a first support section 107.1 in the area of the top of the traction motor unit 104 two first attachment tabs spaced in the transverse direction 104.3 provided on each of which two such pointing in the opposite direction pin-like projections 104.2 are provided to a transverse as possible uniform support of the drive motor unit 104 to achieve. It is understood, however, that in other variants of the invention, a different number of first fastening tabs and / or pin-like projections may be provided. In particular, a single gesture attachment tab may be sufficient with a single pin-like projection.

By inclined to the height direction extending boundary surfaces of the first projection 103.2 and the associated first groove 106.1 is an acting in the height direction first positive connection between the bogie frame 103 and the fastener 106 realized while over the height direction inclined to the boundary surfaces of the second projection 104.2 and the associated second groove 106.2 a likewise acting in the height direction second positive connection between the fastener 106 and the traction motor unit 104 is realized so that the traction motor unit 104 over the fastener 106 in the height direction (as a first support direction) on the bogie frame 103 is supported captively.

Thanks to the respective pairing of projection and complementary recess is limited by the longitudinal direction extending boundary surfaces of the first projection 103.2 and the first groove 106.1 furthermore, a third positive connection between the bogie frame acting in the longitudinal direction (x direction) 103 and the fastener 106 realized. Consequently, this means that a form fit in a second support direction (x-direction) is realized, which extends transversely to the first support direction (z-direction). Likewise, over the longitudinal direction inclined extending boundary surfaces of the second projection 104.2 and the second groove 106.2 also acting in the longitudinal direction fourth positive connection between the fastener 106 and the traction motor unit 104 realized. Accordingly, the traction motor unit 104 over the fastener 106 likewise positively locking in the longitudinal direction captive on the bogie frame 103 supported.

Due to the complementary design of the projections 103.2 respectively. 104.2 and the grooves 106.1 respectively. 106.2 is the fastener 106 basically suitable, from the weight of the traction motor unit 104 resulting moments in the bogie frame 103 initiate. However, the introduction of bending moments in the fastener 106 to reduce and allow the compensation of manufacturing tolerances are the projections 104.2 about a transversely extending axis rotatable on the fastening tab 104.3 arranged.

The first groove 106.1 and the second groove 106.2 are facing away from each other, so that the fastener 106 has a substantially S-shaped shape. Furthermore, the first groove 106.1 and the second groove 106.2 partially wedge-shaped so that it interacts with the complementary portions of the projections 103.2 respectively. 104.2 advantageously comes to a self-centering of the respective positive connection. It is understood, however, that in other variants of the invention, an alignment of the fastener with respect to the bogie frame and / or the traction motor unit can be done in other ways or by separate adjustment means or the like.

The second groove 106.2 is further designed so that its groove bottom facing away from the opening is narrowed such that the second projection 104.2 not up from the second groove 106.2 can be led out. This is thus realized in a simple way, a further captive.

To support from the weight of the drive motor unit 104 resulting moments is in one in the area of the underside of the traction motor unit 104 arranged second support section 107.2 furthermore a second fastening strap 104.4 arranged at the free end of a support element 104.5 is attached, which has a third support portion 103.3 of the bogie frame 103 contacted. The fastening strap 104.4 is in the transverse direction (y-direction) approximately in the middle between the two fastening tabs 104.3 arranged.

The contact surfaces between the support element 104.5 and the third support section 103.3 are designed so that a positive connection in the longitudinal direction (x-direction) is realized. In the present example, the contact surfaces extend perpendicular to the longitudinal direction. It is understood, however, that in other variants of the invention, any other, inclined to the longitudinal direction arrangement of the contact surfaces can be selected to realize the positive connection. Furthermore, it is understood that in other variants of the invention, a frictional connection or a combination of a positive and a frictional connection can be selected.

The support element 104.5 is to compensate for manufacturing tolerances in turn about an axis extending in the transverse direction (y direction) axis rotatably mounted on the second fastening tab 104.4 stored. This also has that over the support element 104.5 primarily a supporting force in the direction of the longitudinal axis in the traction motor unit 104 is initiated.

How the particular 3 can be seen, the drive motor unit 104 in the present example, from a (in 3 through the dashed outline 110 indicated) start position from the bottom 103.4 of the bogie frame 103 into the bogie frame 103 used. This is the drive motor unit 104 in an assembly movement on a mounting path 108 until her (in 3 through the dotted contour 111 indicated support position out.

During this assembly movement, the traction motor unit defines 104 an envelope 109 , the again a midline 109.1 defined, which runs along the mounting direction. This envelope 109 represents a minimum required mounting channel for the assembly of the traction motor unit 104 , hence the movement of the traction motor unit 104 in their supporting position, is to be kept clear.

Again 3 can still be seen, are the fasteners 106 when inserting the traction motor unit 104 in the bogie frame 103 initially both from the bogie frame 103 as well as the traction motor unit 104 away. Only when the drive motor unit 104 a relative to the support position by a distance H has slightly increased intermediate position has reached, as in 4 is indicated, the fasteners 106 in a locking direction extending in the transverse direction (y direction) (from both sides of the respective fastening tab 104.3 fro) between the bogie frames 103 and the traction motor unit 104 used. When this is done, the traction motor unit becomes 104 lowered into its supporting position, in which they are above the fasteners 106 and the support element 104.5 on the bogie frame 103 is supported.

Thanks to the first during the assembly movement in the manner described removed or not existing fasteners 106 can the second projection 104.2 on the drive motor unit 104 (in the longitudinal direction) at a very small distance D to the bogie frame 103 , in particular to the first projection 103.2 , Are passed without this, an evasive movement transverse to the mounting direction, in particular in the longitudinal direction (x-direction) and / or the transverse direction (y-direction) is required.

This makes it possible in the present example, in particular, the mounting channel 109 or its center line 109.1 in the mobility limited mounting sections where the traction motor unit 104 through adjacent components of the bogie 102 (especially the bogie frame 103 ) is limited in their free mobility, to make straight.

As a result, on the one hand achieved that the mounting channel 109 takes up as little space as possible. On the other hand, this is a particularly easy to bewerkstelligende mounting movement of the drive motor unit 104 achieved, namely in the present example, a simple rectilinear lifting movement in the height direction.

The midline 109.1 runs in the example shown (see 3 ) in the mobility restricted mounting portions between a starting point 109.2 and an endpoint 109.3 straight.

The starting point 109.2 and the endpoint 109.3 are in the present example by the intersection of the center line 109.1 with the plane perpendicular to the height direction in the start position (see Contour 110 in 3 , which marks the entry into the mobility restricted mounting sections) or the support position (see contour 111 in 3 ), in which the longitudinal axis of the drive shaft of the traction motor unit 104 lies. It is understood, however, that in other variants of the invention, any other reference point of the traction motor unit 104 can be selected to define the starting point and the end point on the centerline of the mounting channel.

As 3 through the dash-dotted contour 112 is indicated, in other variants of the invention, also any other (in sections rectilinear and / or partially curved) course of the mounting channel 109 and the midline 109.1 between the starting point 109.2 and the endpoint 109.3 be provided. Preferably, the maximum distance A is between the center line 112 and the connection line of the starting point 109.2 and the endpoint 109.3 less than 15% of the maximum dimension M of the traction motor unit 104 (in the direction of the distance A). As a result, as close as possible to the rectilinear course of the assembly channel is achieved with a small footprint and easy to be realized assembly movement.

In the present example, the mounting channel runs 109 , whose midline 109.1 and thus also the mounting direction parallel to the height direction. It is understood, however, that in other variants of the invention it can be provided that the center line of the mounting channel or the mounting direction can be inclined to the height direction. Preferably, the inclination is less than 30 ° in order to achieve as simple as possible to realize assembly movement.

Once the fasteners 106 in her in the 1 and 2 are shown locking position and the traction motor unit 104 is in its support position, the fasteners 106 about security elements 113.1 . 113.2 a safety device 113 in their position relative to the bogie frame 103 and the traction motor unit 104 secured. In particular, this prevents that the fasteners during operation of the vehicle 101 (for example due to vibrations) release from its locking position.

In the present example, this one backup plates 113.1 with the bogie frame 103 bolted to a movement of the fastener 106 in the transverse direction too prevent. Furthermore, the fasteners 106 about securing screws 113.2 with the projections 104.2 screwed. It is understood, however, that any other security elements can be used.

Finally, the support element 104.5 still with the second support section 103.3 of the bogie frame 103 bolted to realize a lift-off in this area. Again, it is understood that any other suitable securing mechanism may be used.

The only difference from the execution 1 to 4 consists in the design of the fasteners 206 , in particular the first recess 206.1 and the second recesses 206.2 , both not as a groove but as a simple passage opening in the fastener 206 are formed. Accordingly, the first projection 203.2 designed differently, namely (similar to the second projection 104.2 ) as a transversely aligned pin-like projection on a fastening tab 203.1 of the bogie frame 203 ,
