[0001] Wire guide element, brake for braking a shaft and brake motor with brake

[0002] Description:

[0003] The invention relates to a wire guide element, a brake for braking a shaft and a brake motor with brake.

[0004] It is generally known that a ferromagnetic magnetic body can be used as the coil core of an electromagnet and that a winding of the electromagnet can be wound onto a plastic coil carrier.

[0005] The invention is therefore based on the object of designing a wire guide element in a simple and cost-effective manner and of making an electromagnetically actuated brake and a brake motor with such a wire guide element simple and cost-effective to manufacture.

[0006] According to the invention, the object is achieved in the wire guide element according to the features specified in claim 1, in the brake and in the brake motor according to the features specified in claim 15.

[0007] Important features of the invention in the wire guide element, in particular for a coil having a winding body and a winding, are that the wire guide element is held in a force-fitting manner, in particular wherein the wire guide element is inserted into a radial slot of the winding body and is elastically prestressed and / or held in a force-fitting manner, wherein the wire guide element has a first and a second slot, in particular a slot open towards the environment, wherein the first slot is formed parallel to the second slot, wherein the first slot is deeper, in particular therefore longer, than the second slot,

[0008] ISI \ EIDOPAT 22.04.2024 in particular wherein the slot width of the first slot is larger than the diameter of the

[0009] winding wire and less than twice, in particular 120%, the diameter of the

[0010] winding wire, in particular wherein the slot width of the second slot is greater than the diameter of the winding wire and less than twice, in particular 120%, the diameter of the winding wire, in particular wherein the winding body is an inner pole of an electromagnet, in particular of an electromagnetically actuated brake, wherein the winding is wound onto the winding body.

[0011] The advantage here is that the different depths of the two slots allow wire paths to be kept as short as possible, and that the wire enters tangentially at the beginning of the winding and exits tangentially at the end. Wire tension is maintained, so that the wire guide element is pressed radially inward by the winding wire and therefore cannot move out of the radial slot.

[0012] In an advantageous embodiment, the wire guide element is U-shaped. This is advantageous because the elastic deflection of the two legs of the U relative to each other creates a preload, which then creates a force-locking connection with the winding support, in particular the inner pole of the electromagnet or the brake.

[0013] In an advantageous embodiment, the wire guide element has a first leg, which is connected to a second leg of the wire guide element via a yoke region of the wire guide element, in particular wherein the slots are aligned parallel to the legs. In particular wherein the wire guide element, together with its legs and the yoke region, is designed as a single piece, in particular one-piece, and / or is designed as a plastic injection-molded part. The advantage here is that the wire guide element is simple and cost-effective to manufacture and can be easily and securely fastened in a radial slot, and a tangential entry and exit of the winding wire is enabled.

[0014] In an advantageous embodiment, contact pins are embedded and / or integrally connected in the yoke area of ​​the wire guide element, in particular wherein the wire guide element is designed as a single piece, in particular a single part, and / or as a plastic injection-molded part. It is advantageous that the wire guide element also has a holding function for the contact pins, which serve for wiring or electrically connecting the winding.

[0015] In an advantageous embodiment, a first collar, in particular a bead, and a second collar, in particular a bead, are formed on the wire guide element for axial delimitation of the wire guide element, in particular wherein the first collar extends continuously from the first leg across the yoke region to the second leg, in particular wherein the second collar is interrupted by the yoke region and extends on the first leg and extends on the second leg, in particular wherein the respective collar is designed to widen the leg width of the respective leg. It is advantageous in this case that the two collars delimit the wire guide element in one direction.

[0016] Important features of the brake, in particular for a brake motor, for braking a shaft, comprising a magnetic body and an electrically energizable winding, are that the magnetic body has an inner pole, in particular wherein the inner pole is made of ferromagnetic material, wherein the winding is wound, in particular directly, onto the inner pole, wherein the inner pole has a first collar which projects radially at the inner pole, wherein the first collar of the inner pole has a recess, in particular a radial slot, which is open in particular towards the surroundings of the inner pole and / or radially outward, wherein the radial spacing region covered by the recess overlaps the radial spacing region covered by the winding, wherein an above-mentioned wire guide element is inserted into the recess,in particular wherein the winding axis of the winding is aligned coaxially with the cylinder axis of the hollow cylindrical outer pole and / or with the axis of rotation of the shaft.,

[0017] The advantage here is that the wire guide element can be inserted into the radial slot from the outside and is elastically pressed upon insertion, so that the wire guide element is force-fitted and can guide the wire entering and exiting the winding. For this purpose, the first slot is deeper, and in particular longer, than the second slot, so that the incoming wire is guided radially deeper, and in particular longer, than the outgoing wire. The two slots are aligned parallel and separated only by the center leg. The center leg is aligned parallel to both the first leg and the second leg.

[0018] The slot width of the radial slot is slightly smaller than the extension of the wire guide element measured in the tangential direction or in the circumferential direction. In an advantageous embodiment, the magnetic body has an outer pole, in particular, the outer pole being made of ferromagnetic material, the outer pole being hollow-cylindrical, and / or the outer pole being plugged onto the inner pole, in particular being plugged onto it with some play.

[0019] The advantage here is that a plastic coil former is not necessary because the inner pole itself provides the necessary winding space and thus the winding is wound directly onto the inner pole. The inner pole has the two collars to axially define the winding space and in the radial direction the winding space is radially inward from the inner pole and radially outward from the outer pole. The outer pole is placed axially onto the inner pole and axially defined by the second collar of the inner pole, with a shoulder formed on the second collar which centers the outer pole relative to the inner pole, in particular so that the cylinder axis of the outer pole is aligned with the winding axis of the winding and / or the axial direction, i.e. the direction of the axis of rotation of the shaft.

[0020] Although a radial clearance is permissible between the outer pole and the first collar, this clearance is not sufficient to provide an air gap that would adequately prevent a field leakage. Therefore, the second collar is designed to taper radially outward, causing this tapered area to saturate even at low current flow to the winding and essentially acting as an air gap at rated current. This prevents a significant field leakage, particularly a magnetic short circuit between the outer pole and inner pole.

[0021] In an advantageous embodiment, the inner pole is hollow, in particular with the shaft projecting axially through the inner pole. The advantage here is that a fan can be connected in a rotationally fixed manner to the shaft on the side of the brake facing away from the stator of the electric motor, thus further improving cooling of the brake. Alternatively, an angle sensor for detecting the angular position of the shaft can also be arranged on the side of the inner pole facing away from the stator of the electric motor. In an advantageous embodiment, the inner pole has an electrically insulating layer, in particular at least in the area arranged axially between the first collar and the second collar, in particular with the electrically insulating layer being a layer of paint or a plastic overmolding. The higher insulation strength is advantageous here.Thus, the self-insulated winding wire, in particular self-bonding wire, of the winding is separated from the metallic inner pole by means of an additional layer. The insulation strength is thus improved. In particular, this layer delimits the winding, i.e., the insulating layer is arranged at least on the outer surface of the inner pole in the surface area arranged axially between the two collars and on the side of the first collar facing the second collar, as well as on the side of the second collar facing the first collar. As a lacquer layer, the layer can be produced quickly and easily. Alternatively, a more complex plastic overmolding can also be provided.

[0022] In an advantageous embodiment, through holes and non-through holes, in particular blind holes, are introduced into the outer pole in the axial direction. The advantage here is that the spring parts can be accommodated in the blind holes, thus providing guidance during the linear movement.

[0023] In an advantageous embodiment, the inner pole, with the exception of bores and at least one recess, in particular a radial slot, is a rotating body whose axis of symmetry is aligned coaxially with the cylinder axis of the hollow-cylindrical inner pole, in particular wherein the radial spacing area covered by the recess overlaps the radial spacing area covered by the winding. This is advantageous in that simple machining is possible and the electrical connection lines of the winding can be passed through the radial slot.

[0024] In an advantageous embodiment, the inner pole has a first collar that protrudes radially from the inner pole, and a second collar that is axially spaced from the first collar and protrudes radially from the inner pole, in particular wherein the inner pole is formed integrally with the first collar and the second collar, in particular as a single piece. The advantage here is that the winding space is axially delimited by the two collars, and the lines that would otherwise pose a danger remain within the winding space. Furthermore, the inner pole and the outer pole can be manufactured simply and cost-effectively, in particular as turned parts.

[0025] In an advantageous embodiment, the outer diameter of the second collar is larger than the outer diameter of the first collar. The advantage here is that during production the hollow cylindrical outer pole can be slipped over the first collar and thereby rests against the second collar, which thus acts as a contact surface and axial limitation. In addition, screws protrude through the second collar and the outer pole so that the outer pole can be connected to the second collar by means of the screws and nuts screwed onto the screws. The outer pole surrounds the first collar to form a housing. As a result, the radially outer end region of the first collar, which tapers radially outwards and is therefore fragile, is protected from the outer pole.

[0026] In an advantageous embodiment, the outer pole radially surrounds the first collar, in particular, the radial spacing region covered by the first collar being arranged radially within the radial spacing region covered by the outer pole, the region covered by the outer pole in the axial direction encompassing or overlapping the region covered by the first collar in the axial direction. It is advantageous that the first collar, including the winding space, is surrounded by the outer pole in a protective and housing-forming manner.

[0027] In an advantageous embodiment, the area covered by the outer pole in the axial direction borders on the area covered by the second collar in the axial direction, in particular directly, i.e. in particular the outer pole rests on the second collar. It is advantageous in this case that the outer pole is spatially aligned relative to a flat surface section of the second collar, in particular which has a single axial position. In an advantageous embodiment, the inner pole is made of a first material and the outer pole is made of a second material, wherein the first material has a lower magnetic saturation flux density than the second material. It is advantageous in this case that two different materials can be used, thus enabling optimization of the material selection depending on the magnetic flux density and loading force.In particular, a force that loads the inner pole is introduced into the inner pole by means of the spring parts, whereas the outer pole only conducts magnetic flux density and is not exposed to any such loading force.

[0028] In an advantageous embodiment, the first material is gray cast iron and / or a cast iron material made of GGG and / or a ferritic cast iron with spheroidal graphite, and the second material is steel. This allows for simple and cost-effective production. In particular, the outer pole can be manufactured as a simple turned part, and the inner pole as a cast part.

[0029] In an advantageous embodiment, the wall thickness of the first collar, measured in the axial direction, decreases monotonically with increasing radial distance, particularly in a radially outer end region of the first collar. This is advantageous because the end region saturates even at low magnetic flux and thus acts as an air gap for the magnetic flux exceeding it. This prevents or at least minimizes a magnetic short circuit between the first collar and the outer pole.

[0030] In an advantageous embodiment, the first collar has a conical surface section in one or the radially outer end region. This is advantageous in that simple manufacturing is enabled, in particular by assigning a flat surface section of the first collar to the conical surface section, which has only a single axial position.

[0031] In an advantageous embodiment, spring parts are accommodated in the non-through holes of the outer pole, which press against an armature disk of the brake. This is advantageous in that an easily manufactured guide and holder for the spring parts is enabled. In an advantageous embodiment, axially through holes are provided in the second collar, through which screws protrude, which protrude through the axially through holes of the outer pole, in particular through recesses of the armature disk. This is advantageous in that

[0032] In an advantageous embodiment, the armature disk is non-rotatably connected to the magnetic body, in particular to the inner pole and / or the outer pole, and is arranged to be displaceable in the axial direction. This is advantageous because frictional force can be introduced into the armature disk and then transferred to the stationary part of the brake.

[0033] In an advantageous embodiment, a disk-shaped brake pad carrier is connected to the shaft in a rotationally fixed manner and is arranged to be displaceable in the axial direction, in particular wherein an annular driver is placed on the shaft and is connected to the shaft in a rotationally fixed manner, in particular by means of a keyway connection or press connection, wherein the driver has external teeth onto which the internal teeth of the brake pad carrier are placed, in particular so that the brake pad carrier is connected to the driver in a rotationally fixed manner and is arranged to be displaceable in the axial direction, wherein the armature disk is arranged axially between the magnetic body and the brake pad carrier and wherein the brake pad carrier is arranged axially between a part of the armature disk having a braking surface, in particular wherein the brake pad carrier has a brake pad on each axial side. The advantage here is that cost-effective production of the brake is possible.In addition, the brake engages automatically when the winding is de-energized. The spring elements then press the armature plate onto the brake pad carrier, which is then pressed onto the braking surface on the side of the brake pad carrier facing away from the armature plate. Optionally, the brake pad carrier and its brake pads can also be mounted as a single piece.

[0034] In this document, external gearing always includes an external polygon, in particular a hexagon; in this document, internal gearing always includes an internal polygon.

[0035] Important features of the brake motor are that the brake motor has an electric motor and the aforementioned brake, wherein the shaft is a rotor shaft of the electric motor, in particular wherein the part is designed as a bearing shield or as a friction plate, in particular wherein the part is connected to the magnetic body in a rotationally fixed manner.

[0036] The advantage here is that the brake motor is easy and cost-effective to manufacture, as the winding can be wound directly onto the inner pole, thus allowing the brake and thus the brake motor to be designed with the smallest possible volume and / or compactness. The outer pole, which is made of steel, can be manufactured easily and cost-effectively by turning.

[0037] Further advantages emerge from the dependent claims. The invention is not limited to the combination of features in the claims. Further possible combinations of claims and / or individual claim features and / or features of the description and / or the figures will become apparent to those skilled in the art, particularly from the problem and / or the problem posed by comparison with the prior art.

[0038] The invention will now be explained in more detail using schematic illustrations:

[0040] Figure 2 shows a longitudinal section of the brake magnet body.

[0041] Figure 3 shows an exploded view of the brake magnet body.

[0042] Figure 4 shows a sectional view of the brake.

[0043] Figure 5 shows a wire guide element 50 attached to the magnet body.

[0044] In Figure 6, the wire guide element 50 is shown in an oblique view.

[0045] Figure 7 shows the wire guide element 50 in front view.

[0046] Figure 8 shows the wire guide element 50 in side view.

[0047] As shown in the figures, the magnetic body has an annular outer pole 2, which is pushed onto an inner pole 1 of the magnetic body.

[0048] The magnet body is therefore made of two parts and different materials can be used.

[0049] In particular, the material used for the outer pole 2 is a material whose magnetic saturation flux density is higher than that of the material of the inner pole 1.

[0050] Preferably, steel is used as the material for the outer pole 2, and gray cast iron and / or GGG cast material, in particular ferritic spheroidal graphite cast iron, is used as the material for the inner pole 1. This makes machining easy. The outer pole 2 is hollow-cylindrical in shape, with circumferentially spaced, axially continuous and axially non-continuous bores, in particular axial bores, provided. Spring parts 3 are inserted into the axially non-continuous bores, i.e., blind bores, which are thus supported on the outer pole 2 and press against an armature disk 43 of the brake.

[0051] Screws 4 extend through the axially through bores of the outer pole 2, which also extend through recesses in the armature disk 43, so that the armature disk 43 is arranged to be movable in the axial direction and is rotationally fixed to the outer pole 2. Additionally or alternatively, guide bolts can also be provided, which extend through recesses in the armature disk 43 and are fastened to the outer pole 2.

[0052] An annular driver 41 is placed on the shaft to be braked by the brake, in particular the rotor shaft, which driver has an external toothing and is connected to the shaft in a rotationally fixed manner, in particular by means of a key connection.

[0053] A disc-shaped brake pad carrier 42 is mounted with its internal teeth on the external teeth, with the internal teeth meshing with the external teeth. Thus, the brake pad carrier 42 is connected to the driver 41 in a rotationally fixed manner, yet is still axially displaceable.

[0054] On the side of the brake pad carrier 42 axially facing away from the armature disk 43, a braking surface 40 is formed, in particular on a friction plate received in a housing part 44 or on a bearing plate of an electric motor, which receives a bearing of the rotor shaft of the electric motor.

[0055] The armature disk 43 is arranged axially between the brake pad carrier 42 and the outer pole 2. The brake pad carrier 42 is arranged axially between the armature disk 43 and the braking surface. An electrically energizable winding 5, in particular a coil winding, is wound on the inner pole 1. When energized, the armature disk 43 is pulled toward the magnet body, in particular toward the outer pole 2, against the spring force generated by the spring parts 3, so that the brake pad carrier can move freely from the braking surface.

[0056] When the winding 5 is not energized, the spring parts 3 press the armature disk 43 onto the brake pad carrier 42, which is thus pressed onto the braking surface located on its side facing away from the armature disk 43. This creates a frictional connection on both sides of the brake pad carrier 42, particularly with the braking surface on the one hand and with the armature disk 43 on the other.

[0057] Preferably, the winding 5 is wound directly onto the inner pole 1, so that no plastic part, in particular a coil carrier, is necessary in between.

[0058] The inner pole 1 has a first, radially protruding collar 31, which delimits the winding 5 in the axial direction, and a second, radially protruding collar 32, which delimits the winding opposite to the axial direction. The second collar 32 preferably protrudes further than the first collar 31, so that the hollow-cylindrical outer pole 2 rests against an axial end face of the second collar 32 and the first collar 31 is arranged radially inside the outer pole 2.

[0059] The area covered by the outer pole 2 in the axial direction comprises the area covered by the first collar 31 in the axial direction, in particular and the area covered by the winding in the axial direction.

[0060] The first collar 31 has a flat axial end face which functions as pole face 33.

[0061] At its radially outer end region, the first collar 31 is tapered, so that the axial wall thickness of the first collar 31 decreases monotonically, in particular strictly monotonically, with increasing radial distance. Therefore, the first collar 31 has a bevel 6, in particular a conical surface, in this radial end region. Due to this tapered shape, the tapered region reaches magnetic saturation even at low current flow to the winding and thus acts primarily as an air gap between outer pole 2 and inner pole 1. Nevertheless, the axial limitation of the winding 5 is reached.

[0062] The radial direction and radial distances are always relative to the shaft's rotational axis. The axial direction is parallel to the shaft's rotational axis, and the circumferential direction is relative to the shaft's rotational axis. The winding axis of winding 5 is coaxial with the winding's rotational axis.

[0063] The area covered by the second collar 32 in the axial direction borders on the area covered by the outer pole 2 in the axial direction.

[0064] The inner pole 1 and the outer pole 2 are made of ferromagnetic material.

[0065] The screws 4 protrude through recesses of the second collar, which are arranged radially outside the first collar and are aligned with the corresponding recesses of the outer pole 2, through which the screws 4 also protrude.

[0066] A recess 30 is formed as a radial slot, in particular a notch or radially directed depression, in the second collar 32, allowing the connecting leads of the winding 5 to pass through. The radial spacing area covered by the radial slot overlaps the radial spacing area covered by the winding 5.

[0067] With the exception of the recess 30 and the recesses through which the screws 4 protrude, the inner pole 1 is designed as a rotating body.

[0068] To allow the shaft to be braked by the brake, in particular the rotor shaft of the brake motor having the brake, to protrude axially through the brake, the inner pole 1 is hollow. Thus, the brake can be mounted on an electric motor of the brake motor, and an angle sensor for detecting the rotational position of the shaft and / or a fan can be arranged on the side of the brake axially facing away from the stator of the electric motor.

[0069] The pole face 30 is formed axially flush with the outer pole 2, in particular wherein the axial position of the pole face 30 limits the area covered by the outer pole 2 in the axial direction, in particular in the axial direction.

[0070] As shown in Figures 5 to 8, a wire guide element 50 is inserted into the recess 30, in particular the radial slot.

[0071] The wire guide element 50 has a U-shape with an additional central leg. A first leg 61 of the wire guide element 50 and a second leg 60 of the wire guide element 50 are connected via a yoke region 64 of the wire guide element 50.

[0072] The two legs (60, 61) each have an insertion bevel on their outer side, which comes into contact with the slot edges of the recess 30, in particular the radial slot, when the wire guide element 50 is inserted, wherein the legs (60, 61) are elastically deflected as a result of the widening caused by the insertion bevels, so that the wire guide element 50 is clamped in the recess 30, in particular the radial slot.

[0073] A first slot 71, in particular a notch or a first radially directed depression, and a second slot 70, in particular a notch or a second radially directed depression, are introduced into the yoke region 64 parallel to the legs (60, 61), both of which are designed to be parallel to one another and are also aligned parallel to the two legs (60, 61).

[0074] Thus, the slots (70, 71) are essentially radially directed, although they have different radial depths. Both slots (70, 71) are open radially outwards and have a different minimum radial distance from the axis of rotation of the shaft. They are therefore cut into the yoke area to different radial depths, thereby forming the center leg. In this way, when winding the coil winding 5, the winding wire can first be guided through the first slot 71 into the winding space arranged between the two collars (31, 32) and, after winding the coil winding 5, can be guided out of the winding space through the second slot 70.

[0075] Embedded in the wire guide element 50 are metallic contact elements 80, in particular contact pins, to which the ends of the winding wire are attached to enable contact with electrical lines. Both a respective stripped electrical line and a respective end of the winding wire are electrically connected to the respective contact element 80, in particular contact pin.

[0076] At its axially rear edge region, the wire guide element 50 has a first collar 62, in particular a bead, which functions as an axial boundary for the wire guide element 50. The first collar 62 extends along the legs (60, 61) and along the yoke region 64. The first collar 62 extends continuously from the first leg 61 across the yoke region 64 to the second leg 60 and protrudes in the tangential direction on the first leg 61 and in the opposite direction to the tangential direction on the second leg 60.

[0077] At its axially front edge region, the wire guide element 50 has a second collar 63, in particular a bead, which acts as an oppositely directed axial limit for the wire guide element 50. The second collar 63 extends along the legs (60, 61) - but not along the yoke region 64. The second collar 63 is discontinuous and protrudes in the tangential direction on the first leg 61 and opposite to the tangential direction on the second leg 60.

[0078] The two collars (62, 63) thus axially limit the wire guide element 50 in both directions. In particular, the slot width of the first slot 71 is larger than the diameter of the winding wire, but less than 120% of the diameter of the winding wire.

[0079] In particular, the slot width of the second slot 70 is also larger than the diameter of the winding wire, but smaller than 120% of the diameter of the winding wire.

[0080] Preferably, the wire guide element 50 is manufactured as a plastic injection-molded part.

[0081] In further embodiments according to the invention, the pole face 30 projects axially so that the area covered by the first collar 31 in the axial direction overlaps the area covered by the outer pole 2 in the axial direction.

[0082] In further embodiments according to the invention, the inner pole 1 has an electrically insulating layer to increase the insulation strength. This can be provided as a lacquer layer or as a plastic overmold. Preferably, the contact surface toward the outer pole 2 is free of the insulating layer.
