Definitions
- the invention relates to a load adjustment device with a throttle valve arranged in a throttle valve housing for controlling the power of an internal combustion engine according to the preamble of patent claim 1.
- a load adjustment device is known from DE 38 15 735 A1, in which a throttle valve is rotatably mounted in a throttle valve housing.
- the throttle valve is set as a function of predefinable parameters by an actuating device, in particular an electric motor, for controlling the output of the internal combustion engine.
- an actuating device in particular an electric motor, for controlling the output of the internal combustion engine.
- a throttle valve potentiometer with its own wiring and also the electric motor with its own wiring, which must be individually led out of the throttle valve housing, are arranged separately in the throttle valve housing.
- This arrangement has the disadvantage that the assembly effort is considerable due to a large number of components and there is a risk of a cable break due to the use of the wiring.
- the invention is therefore based on the object of designing a load adjustment device of the type mentioned at the outset such that maintenance of the compact design of the assembly effort is simplified and the risk of line breaks is avoided.
- a carrier plate with electrically conductive areas has the advantage that the wiring can be omitted, in particular if the electrically conductive areas are connected to the electrical connection (plug).
- Another advantage is that when assembling the load adjustment device, the support plate only has to be inserted into the throttle valve housing, so that additional handles such as e.g. There is no need to lay the cables or solder them or the like. This is of particular advantage in the case of series production of load adjustment devices, since this results in a considerable time advantage in production.
- the actuating device which is designed as an electric motor, has, in a manner known per se by means of springs, coals connected to a collector of the electric motor, at least the coals and the springs being arranged on and / or in the carrier plate.
- This has the advantage that elements of the electric motor can also be preassembled in the carrier plate, so that the wiring of the electric motor is also eliminated.
- the carrier plate accommodates interference suppression means, for example interference suppression chokes, interference suppression capacitors or the like, for the actuating device.
- interference suppression means for example interference suppression chokes, interference suppression capacitors or the like.
- the carrier plate has an electrical connector, a plug or a socket, the plug and / or the socket being configured in one or more parts, in particular in two parts.
- the plug or socket can form a unit with the carrier plate, which is particularly advantageous in the manufacture of the carrier plate, or can be designed as a separate component, which then has the advantage that different types of plugs or sockets, which can have different shapes, for example depending on the respective manufacturer, and can be attached to the carrier plate, for example by means of screwing, gluing or the like.
- a seal is provided between the plug or the socket or the parts of the plug or the socket and the throttle valve housing.
- a plurality of path regions of a throttle valve potentiometer are arranged on the carrier plate for detecting the position of the throttle valve, the carrier plate extending around a region of a throttle valve shaft and the plurality of path regions being arranged concentrically around the throttle valve shaft.
- a discharge resistor is connected between a connection, in particular between an electrical connection connected to a carbon of the electric motor and the throttle valve housing.
- a connection in particular between an electrical connection connected to a carbon of the electric motor and the throttle valve housing.
- the electrically conductive areas of the carrier plate are designed as conductor tracks arranged on the carrier plate.
- the conductor tracks can be produced, for example, by etching away the entire, electrically conductive areas on the carrier plate that are not required.
- the carrier plate has a multilayer structure, the electrically conductive regions being inserted between an electrically non-conductive upper and lower layer. This is particularly advantageous if, for example, high currents flow to the electric motor for which the conductor tracks would not have been designed.
- the carrier plate is formed in several parts and an electrical transition of the respective electrically conductive regions is provided in the connection area, in particular the end faces, of the plurality of carrier plate parts. This advantageously allows several carrier plate parts to be joined together in a kind of modular system, which can differ according to their geometric extension or other specifications.
- a base carrier plate which, on the one hand, receives the electrical connection and the springs of the electric motor and, on the other hand, an additional carrier plate can be connected to it, which receives the multiple path areas of the throttle valve potentiometer.
- the plurality of carrier plate parts can, for example, accommodate bores, engage in the pins of the throttle valve housing after assembly and fix the position of the carrier plate parts.
- the carrier plate or the plurality of carrier plate parts can be fixed by the throttle valve housing and a cover or other cover closing the throttle valve housing.
- the invention allows a variety of configurations, in particular with regard to the geometric configuration of the carrier plate, a preferred embodiment, without the invention being restricted to this embodiment, being described below and explained with reference to the figures. Show it:
- FIGS. 1 to 3 different side views of a carrier plate
- Figure 4 the structure of a multi-part connector.
- FIGS. 1 to 3 show different views of a carrier plate 1 which can be inserted into a throttle valve housing of a throttle valve connector, the same components having been given the same reference numbers.
- the carrier plate 1 is designed as a flat plate, but can also have complex geometric contours, as are shown, for example, in FIGS. 1 to 3.
- the carrier plate 1 consists of a first layer 2 and a second layer 3, a plurality of insert sheets 4, which represent the electrically conductive region, being inserted insulated from these two layers 2 and 3.
- the two layers 2 can be connected to one another by appropriate measures such as gluing, but it is also conceivable that the carrier plate 1 is cast in one piece with the insert of the electrically conductive areas.
- FIG. 2 additionally shows a fastening bore 11 with which the carrier plate 1 is fixed in position, for example by means of at least one screw, and connected to the throttle valve body in a vibration-proof manner.
- a cable harness 16 with a plurality of cables is arranged on further contacts of the plug 5, which leads to a throttle valve potentiometer (not shown) in this embodiment.
- the cables of the cable harness 16 are arranged as rigid, electrically conductive areas in or on the carrier plate 1 and the carrier plate 1 also accommodates the throttle valve potentiometer in a unit or external part.
- the coals 13 are connected to the electrically conductive area (insert plate 4) via a connecting wire 17.
- FIG. 4 shows an electrical connection in the form of a plug 5, the electrical connection can of course also be designed as a socket.
- the partially illustrated housing of the throttle valve assembly, in which the carrier plate 1 is inserted is shown with the reference number 18.
- the connector 5 shown has a first part 19, which is either arranged on the carrier plate 1 or with the carrier gerplatte 1 forms a structural unit (for example, is cast).
- the second part 20 of the plug 5 is located with the interposition of a circumferential seal 21 in an advantageous manner over the first part 19, the second part 20 of the plug 5 being advantageously adapted to the requirements of the motor vehicle manufacturer in which the load adjustment device is installed .
- a plurality of contact pins 22 are sealingly led out of the first part 19 and are surrounded by the second part 20 in a protective manner.
- a socket contact 23 is provided, which is either connected to the insert plate 4 (looking at FIG. 4, the right contact pin 22), is connected to a cable of the cable harness 16 (looking at FIG. 4 the middle contact pin 22) or is soldered to a conductor track 24, which is located on the upper side of the carrier plate 1 (when looking at FIG. 4, the left contact pin 22).
- a socket contact 23 is provided, which is either connected to the insert plate 4 (looking at FIG. 4, the right contact pin 22), is connected to a cable of the cable harness 16 (looking at FIG. 4 the middle contact pin 22) or is soldered to a conductor track 24, which is located on the upper side of the carrier plate 1 (when looking at FIG. 4, the left contact pin 22).
- only one of the mentioned contacts or a combination thereof is possible.
