Definitions
- the invention relates to a brush system for an electric motor drive and an electric motor drive which is provided with such a brush system.
- An electric drive unit is known from DE 101 29 234 AI.
- This has a gear housing, a motor housing, a separately designed and watertight electronics housing, a brush holder and a signal receiver arranged on the brush holder.
- the brush holder is provided with plug contacts with which electronics provided in the electronics housing are electrically connected. Furthermore, the brush holder is attached to the motor housing in the transition area between the motor housing and the gear housing. Information on cooling measures of whatever kind cannot be found in DE 101 29 234 AI.
- the object of the invention is to show a way how heat energy generated in an electric motor drive can be dissipated effectively.
- Claim 16 relates to an electric motor drive, which has a brush system according to one of Claims 1-15.
- the advantages of the invention are, in particular, that the integration of the resistance unit in the brush system and the special design of the resistance unit as a flat resistor contained in a resistance housing provided with air passage openings can ensure better the flow of the air flow necessary for dissipating the thermal energy generated than in known drive systems , Furthermore, the flat design of the resistance unit and its integration in the brush system result in a compact, space-saving construction.
- the features specified in claim 2 ensure that the brush system can be pushed over the shaft of the motor and attached to the housing of the motor. A space-saving construction is guaranteed, as is safe contacting of the carbon brushes with the commutator bars of the electric motor.
- the air passage openings are holes or slots. These can advantageously be brought into the resistance housing during the manufacturing process of the resistance unit. Care must of course be taken to ensure that the resistance circuit provided inside the resistance housing is not damaged.
- the entire brush system can be designed as a lightweight construction.
- the airflow deflecting elements specified in claim 11 enable targeted guidance of the airflow in the sense that heat can be effectively removed from components which generate a lot of heat and that on the other hand also prevents it can be that dissipated heat is directed directly towards heat-sensitive components.
- the resistance circuit contained in the resistance housing can be a resistance foil, a meandering flat resistance or a meandering resistance wire.
- the gas, liquid and solid-tight design of the resistance housing has the advantage that the components in the housing are protected against corrosion and other damage caused by gases, liquids or solids occurring in the engine compartment.
- a design of the resistance housing in the sense of the features of claim 16 allows gases, liquids or moisture and solids to escape, which have undesirably penetrated into the resistance housing during production and use of the resistance unit.
- FIG. 1 shows a sketch with the components of an electric motor drive essential for understanding the invention
- FIG. 2 shows a sketch of a more detailed view of the brush system 6 of system 1,
- FIG. 3 shows a sketch of the rear view of the brush system 6 and 6 shown in FIG
- FIG. 1 shows a sketch with the components of an electric motor drive that are essential for understanding the invention.
- an electromotive drive has a motor housing, not shown, in which permanent magnets 1 are arranged.
- the motor housing and the permanent magnets form a stator.
- the electric motor drive contains an armature 2, on which coils 3 are provided.
- the armature 2 further comprises an armature shaft 4, on which a commutator with commutator segments 5 is attached, the commutator segments being electrically conductively connected to the respective windings of the coils 3.
- the electromotive drive shown has a brush system 6, which is positioned around the shaft 4 in the assembled state of the drive such that it is directly adjacent to the commutator bars.
- This brush system 6 is attached to the motor housing in the assembled state.
- the armature shaft 1 is mechanically coupled to a fan wheel 7 in the assembled state of the drive and drives it.
- the fan wheel 7 is designed such that when it rotates with the shaft 4, the air flows in the direction indicated by the arrow 8, i. H. in a substantially parallel direction to the shaft 4 of the electromotive drive.
- FIG. 2 shows a sketch of a more detailed view of the brush system 6 from FIG. 1.
- the brush system 6 shown has a base body 9 made of an electrically non-conductive material, for example made of hard paper or made of plastic.
- the base body 9 has an essentially disk-shaped, preferably circular disk-shaped basic shape and is provided with a cutout 18 in its central region.
- Brush support elements 10 are fastened to the base body 9 and are designed, for example, as brush holders.
- the carbon brushes, which contact the commutator bars 5 in the operating state, are mounted within these brush carrier elements 10.
- interference suppression elements for example chokes 11 and capacitors, are fastened to the base body 9.
- a plug connection 12 is provided on the base body 9, via which the brush system can be electrically contacted with an external voltage supply.
- the necessary electrical connections of the components fastened to the base body 9 with one another and with other components are made via current leads 13 provided on the base body.
- These current leads can be realized in the form of a lead frame which has been punched out of a metal plate, as a printed circuit board or as individual conductor tracks, which are either injected into the base body or subsequently applied to it. In the following it is assumed that the current leads are implemented as conductor tracks.
- a resistance unit is integrated in the brush system 6, which has a resistance housing 14 and a flat resistance arrangement provided in this resistance housing, which is always referred to below as flat resistance.
- This flat resistor is a resistance film, a meandering flat resistor or a meandering resistance wire. This flat resistance is used in the context of a stepped speed control of the electromotive drive.
- the resistance housing 14 has an essentially disk-shaped, preferably disk-segment-shaped basic shape on and consists of a light metal, preferably aluminum. This makes it possible to implement the entire brush system in terms of a lightweight construction.
- the resistance housing 14 is a component of the brush system 6.
- the resistance housing 14 is arranged in the same plane as the base body 9 and is inserted in a form-fitting manner in a further, preferably disk-segment-shaped recess in the base body 9.
- the resistance housing 14 is fastened to the base body 9 by means of latching connections 17, into which the resistance housing snaps after it has been inserted.
- the resistance housing is inserted into the cutout of the base body from the underside of the base body.
- connection lugs 16 which are inserted into receiving pockets 20 of the resistance housing 14.
- connection tabs 16 connect the end connections of the
- Flat resistor with one of the conductor tracks 13 each.
- one of the conductor tracks connects an end connection of the flat resistor with a power connection cable which, coming from the outside, is guided into contact of the plug connection 12 of the brush system 6.
- Another one of the conductor tracks 13 connects the other end connection of the flat resistor to one of the carbon brushes via one of the interference suppression elements 11.
- the resistance housing 14 has a large number of air passage openings 15. These can be holes or slots that were already made in the housing during the production of the resistance unit 14. The more ventilation is required, the greater the number of air openings. AI Alternatively or in addition, the size of the air outlet openings can also be changed.
- the air passage openings 15 are arranged in such a way that they allow the air flow to be attributed to the rotation of the fan wheel 7 to pass unhindered. This effectively dissipates the heat generated by the resistance unit.
- the large-area, good heat-conducting housing 14 which transfers heat generated in the interior of the resistance housing to the outside, also contributes to an effective dissipation of the heat generated by the resistance unit.
- the resistance housing 14 is preferably provided with surface-enlarging projections.
- Such extensions are, for example, beads or folds.
- these surface-enlarging extensions can also be airflow deflection elements.
- FIG. 4 shows a sectional view from which one of the holes 15 and the parts of the resistance housing 14 present above and below the hole can be seen.
- the arrows 8 also illustrate the direction of flow of the air. It can be seen that the air conducted through the hole 15 in the resistance housing is diverted through the subsequent air flow deflecting element 19 and has a different flow direction after exiting the air flow deflecting element.
- the flow direction of the air can be influenced by using such air flow deflection elements. It is possible to conduct heat-dissipating air increasingly in areas in which strongly heat-generating components are arranged. There is also the option to prevent dissipated heat is conducted directly in the direction of heat-sensitive components.
- a surface-enlarging extension of the resistance housing 14 can also advantageously connect the resistance housing to the housing of the motor. As a result, heat is also dissipated through the motor housing. This measure also counteracts overheating of the drive unit.
- the resistance housing can be designed to be gas, liquid and solid-tight. This has the advantage that, during operation of the drive unit, it is impossible for gases, liquids or solids occurring in the engine compartment of a motor vehicle in which the drive unit is located to damage the components in the housing. In particular, this prevents corrosion from occurring.
- Resistance housing should also be open.
- This open configuration of the resistance housing has the advantage that gases, liquids or moisture as well as solids which have already undesirably entered the resistance housing during the production process and during use can also be removed from it in a simple manner ,
- the invention relates to a brush system that can be used in an electric motor drive.
- the brush system has a base body, brush support elements and interference suppression elements attached to the base body. Furthermore, current guides are provided on the base body, via which the necessary electrical connections are made.
- a resistance unit which contains a flat resistor arranged in a resistance housing, is inserted into the base body, fastened to it and with it contacted the current leads.
- the resistance housing has air outlet openings that promote an air flow that is due to the rotation of a fan wheel. This air flow effectively dissipates any heat generated, in particular heat generated by the flat resistor during operation.
