Definitions
- the invention relates to an arrangement for fastening a drive device to a support element, a drive device with fastening elements, a fan frame with an air opening, within which a fan support frame is arranged, which is connected to the fan frame via connecting elements, and a heat exchanger arrangement with a heat exchanger and a Fan cover, which comprises a fan with a fan drive and a fan wheel and a fan frame with a fan support frame.
- Known fan hoods are seen in front of or behind a heat exchanger, e.g. B. a _ coolant / air cooler or a cooling module and arranged on the heat exchanger, for. B. attached to its water boxes.
- the fan cover has a fan frame with an air opening, in which a fan for conveying cooling air is arranged.
- the fan comprises, for example, an electric motor, which is usually fastened to the fan frame by means of struts and a retaining ring.
- the fan wheel and the electric motor together form the fan or the fan blower.
- Such fan covers or cooling modules with such fan covers have become known from DE 42 44 039 A1 and DE 42 44 037 C2 from the applicant.
- the fan blower is attached to the known fan cover by screwing or riveting the electric motor to the retaining ring of the fan cover. Such attachment requires additional parts such as screws, nuts and washers or lock washers, which must be assembled individually - this means additional manufacturing costs.
- the fan cover is attached to the cooler or cooling module by means of laterally projecting arms by hanging in, ie. H. a linear movement assembled and fastened.
- Another type of fastening was known from DE 44 21 835 A1, namely a so-called pivot pin / hinge connection between the fan cover and header boxes of the heat exchanger.
- the fan hood is pivoted about an eccentrically arranged pivot pin (on the water tank) and engages with two plug-in tabs arranged on the circumference in U-shaped receiving pockets. The fan cover is thus assembled and fastened together with the fan by a swiveling movement.
- the fan itself is - like the previously mentioned types - screwed to a fastening ring, which in turn is connected to the fan cover via radial struts.
- the fan cover too, the fan must be connected to the fastening ring by means of additional parts such as screws or bolts.
- the attachment of a drive device to a support element should be made easier and less expensive.
- the drive device can be clipped onto the support element.
- the means for the clipping can preferably be arranged in one piece directly on the drive device or on its housing and / or on the support element, or can also be molded on. The assembly is then carried out, for example, by simply plugging in or by plugging and turning, after which a locking takes place.
- the drive device preferably drives a rotating shaft or a wheel, such as a fan wheel, for rotation.
- the support element is preferably a fan support frame, particularly preferably a fan support frame of a fan frame.
- a fan cover consisting of a fan frame and fan can be easily installed under certain circumstances.
- the fan frame has an air opening, within which the fan support frame is arranged.
- the fan support frame is then connected to the fan frame via one or more connecting elements, preferably struts.
- the fan support frame is preferably arranged along an outer circumference of the drive device and, in particular, is designed in a ring shape, the ring shape preferably being in a circular shape, which under certain circumstances results in a simple construction, in particular in the case of drive devices with a circular cross-sectional circumference.
- at least one tab and the supporting element has a corresponding guide and / or holding pocket is provided on the driving device.
- at least one tab on the support element and a corresponding guide groove and / or holding pocket on the drive device direction provided.
- a shape of a bayonet lock is thus preferably achieved, ie the drive device is placed, for example, on the support element, inserted with the tabs into the guide grooves and rotated in the holding pockets until the tabs stop. Under certain circumstances, a sufficient mounting of the drive device is achieved.
- the assembly may be simplified and the assembly time shortened.
- the guide grooves preferably run essentially tangentially and particularly preferably the holding pockets run essentially radially, in each case with respect to an axis of rotation of the drive device.
- additional latching elements are provided, advantageously in the form of elastic tongues, which lock the tabs in their end position. This has the advantage that the fastening is secured at the end of the assembly process, possibly without additional securing means.
- one or more fixing elements are arranged opposite at least one locking element and together with the locking element form a receptacle for a tab.
- the tab can preferably be pressed against the latching element by the fixing element, so that, if necessary, a margin for the tab is reduced or avoided. Under certain circumstances, the tab is then positively fixed in the receptacle.
- the fixing element is preferably designed as a spring element, particularly preferably as a leaf spring.
- one, at least two, in particular three radially protruding tabs on the drive device and corresponding guide grooves, holding pockets and locking elements are provided on the support element. This may result in a stable attachment for the fan.
- guide ribs are assigned to the guide grooves, in particular counter to the installation direction, which serve as installation aids. Under certain circumstances, this achieves the advantage that the drive device with its tabs can be inserted smoothly and essentially guided into the guide grooves and thus into a locked end position.
- some or all of the elements of the clip or bayonet catch on the support frame are made in one piece with the support frame, that is to say, for example, as a plastic injection-molded part, whereby advantageously no slides are required for the molding, since the molding can take place in the direction of the drive axis ,
- locking takes place counter to a direction of rotation of the drive, so that a torque generated by the drive device can be absorbed by a fixed part of the locking.
- the object of the invention is also achieved by a drive device with fastening elements, in which at least one fastening element is designed as a tab, which preferably projects radially outwards, and / or as a guide groove and / or receptacle for a tab.
- the drive device particularly preferably has a housing on which the fastening elements are arranged.
- Such a drive device can be used for a fastening arrangement according to the invention.
- the invention is also achieved by a fan frame with an air opening, within which a fan support frame is arranged, which is connected to the fan frame via at least one connecting element, the fan support frame having one or at least two tabs, in particular projecting radially inwards, and / or one or at least two guide grooves and / or receptacles, such as holding pockets, for one or more tabs.
- a fan frame designed in this way can be used for a fastening arrangement according to the invention.
- the object of the invention is also achieved by a heat exchanger arrangement with at least one heat exchanger and at least one fan cover, the fan cover comprising a fan with a fan drive and a fan wheel and a fan frame with a fan support frame, the fan drive can be fastened to the fan support frame and the fan drive with the fan support frame can be clipped.
- 1 is a mounting arrangement with a support frame of a fan cover and a drive device
- Fig. 2 shows a detail X of Fig. 1 and
- Fig. 3 shows a support frame
- Fig. 1 shows an annular support frame 1 which can be connected via struts 2, 3, 4 with a fan frame, not shown.
- the support frame 1 is arranged centrally within a circular air opening of the fan frame and serves to fasten an electric motor, which is not shown completely, and which is the drive device of a fan, not shown further. All that can be seen of the electric motor is a fastening ring 5, which is part of a housing of the drive device (not shown) and has three radially protruding tabs 6, 7, 8 arranged at its periphery.
- the tabs 6, 7, 8 are flat and rigid and preferably connected in one piece to the fastening ring 5 or the housing jacket of the electric motor, which is closed at the end by a cover 9.
- the motor drive shaft and fan wheel (both not shown) are arranged on the side (not visible) opposite the cover 9.
- the fastening ring 5 is connected to the retaining ring 1 by a bayonet lock: for this purpose, each tab 6, 7, 8 is assigned a guide groove 10, 11, 12, a retaining pocket 13, 14, 15 and a latching element 16, 17, 18.
- each tab 6, 7, 8 is assigned a guide groove 10, 11, 12, a retaining pocket 13, 14, 15 and a latching element 16, 17, 18.
- the bayonet lock thus contains the tabs 6, 7, 8 on the motor side and the lock elements 10 to 18 on the fan hood side and advantageously also the guide ribs 19 to 21.
- Fig. 2 shows the detail X from Fig. 1, i.e. H. the connection between the tab 8 and the support frame 1 by means of the guide groove 12, the holding pocket 15 and the latching element 18, which fix the tab 8 in both circumferential directions and in the radial direction to the outside.
- the holding pocket 15 is aligned radially in accordance with the tab 8 and forms a stop in the circumferential direction and in the axial direction.
- the guide groove 12 is oriented essentially tangentially and forms a tangential guide and a stop in the radial and axial direction for the tab 8.
- the guide groove 12 and the holding pocket 15 thus each comprise a lateral and circumferential part of the tab 8.
- the latching element 18 is a resilient tongue formed with a clamping point 18a and a stop side 18b, wherein lateral slots 18c, 18d are left between the tongue 18 and the retaining ring 1. This gives the possibility of deflection in the axial direction.
- the guide groove 12 has a part 12a which overlaps the tab 8, below which, in the axial direction, a shaping recess 12b is arranged in the support frame 1. An identical recess is provided for an overlapping part 15a of the holding pocket 15 (not visible). This makes it possible to manufacture the support frame 1 made of plastic with the closure elements 10 - 18 without the use of sliders, i. H. only by shaping in the axial direction (direction of the motor axis).
- the drive device with the housing ring 5 is installed in the following manner: the drive device is first inserted with its side facing away from the cover 9 through the central opening of the support frame 1 until the tabs 6, 7, 8 come to rest on the support frame 1 , The drive device is then rotated about its longitudinal axis or axis of rotation until the outer peripheral regions of the tabs 6, 7, 8 come into contact with the guide ribs 19, 20, 21 and thus receive a pre-centering. By further turning the drive device, the load rule 6, 7, 8 in the guide grooves 10, 11, 12 and are thus completely centered until the front side of the tabs 6, 7, 8 in the direction of rotation comes to rest with the holding pockets 13, 14 15.
- the resilient tongues 16, 17, 18 are pressed downwards in the axial direction due to their wedge-shaped design. After reaching the end position, the tongues 16, 17, 18 snap back and thereby lock the tabs 6, 7, 8, so that the drive device is fixed and secured on the support frame 1 and thus in the fan frame.
- Any disassembly that may be necessary can be done by pressing down the tongues 16, 17, 18 and turning them in the opposite direction. This means less disassembly effort, for example compared to a screw connection between the drive device and the support frame.
- Fig. 3 shows a further embodiment of a support frame 30 and a tab 31 of a drive device, not shown.
- the support frame 30 is ring-shaped with a raised edge 40 and has three guide grooves 32, 33, 34 and a locking element 35 designed as a resilient tongue.
- a fixing element 36 which is designed as a leaf spring, is arranged opposite the latching element 35.
- the tab 31 and two further tabs are each placed next to one of the guide grooves 32, 33, 34 on the support frame 30 and by means of a rotary movement, counterclockwise in FIG. 3, into the guide grooves 32, 33, 34 introduced.
- the tab 31 presses the inclined ramp 37 of the locking element 35 downward, so that the locking element 35 makes an evasive movement downward due to its resilient configuration.
- the latching element 35 snaps back into its starting position and thus prevents the tab 31 from slipping out of the guide groove 34.
- the fixing element 36 presses the tab 31 against the latching element 35 and is preferably in a tensioned state for this purpose as a spring.
- the tab 31 is then positively fixed between a base plate 38 of the support frame 30, the locking element 35, the guide groove 34 and the fixing element 36.
- a breakthrough 39 in the tab 31 serves to secure it additionally by means of a further fastening element such as a screw, if this is desired.
- the further tabs and thus the entire drive device are also fixed by a star-shaped alignment of the tabs or the guide grooves 32, 33, 34.
