Definitions
- the invention relates to a throttle valve assembly, in particular for an internal combustion engine of a motor vehicle, with a continuous throttle opening for a throttle valve pivotally arranged on a throttle valve shaft and with a housing, the housing comprising a housing cover and a housing body, in the housing for pivoting the throttle valve shaft an electric actuator and a first electronics are arranged.
- the invention further relates to an electronics module that includes electronics for a motor vehicle and a base element that can be closed by a cover element, the motor vehicle having a large number of electrical devices and a throttle valve assembly, the throttle valve assembly being a housing with a continuous throttle opening for a throttle valve shaft pivotally arranged throttle valve and an electric actuator arranged in the housing for pivoting the throttle valve shaft.
- Throttle valve connectors are usually used to control the amount of fresh gas to be supplied to the internal combustion engine of a motor vehicle.
- Throttle valve bodies comprise a housing with a continuous throttle opening and a throttle element arranged in the throttle opening.
- the throttle element assumes a certain position in the throttle opening for the passage of a certain amount of fresh gas.
- the throttle element can be controlled mechanically or electronically.
- the throttle valve of a throttle valve connector can be moved by an actuator in a partial area, for example the idling area, and can be moved in the remaining area with the aid of a wire cable coupled to the gas pedal of the motor vehicle. Alternatively, the throttle valve can also be moved by an actuator in its entire adjustment range.
- throttle valve bodies in which the control unit for the actuator is integrated in the housing of the throttle valve body.
- the control unit can be integrated into electronics arranged in the housing.
- the electronics are provided for further functions of the throttle valve body, for example for the control of a position control of the throttle valve shaft and the acquisition and storage of data of the throttle valve body.
- An integration of electronics in the housing of the throttle valve assembly is often associated with a particularly large manufacturing and assembly effort, since the housing must also have a receptacle for the electronics.
- an additional assembly step is required to assemble the throttle valve assembly, in which the electronics are integrated into the housing of the throttle valve assembly.
- a connection of the electronics of the throttle valve assembly to the other electronics of the motor vehicle is required, for example, to coordinate the position of the throttle valve with the operation of an ignition device and / or an injection device.
- This connection of the electronics of the throttle valve assembly with other electronics, in particular control electronics, of the motor vehicle requires a particularly high amount of assembly work when installing the throttle valve assembly or E-gas system in a motor vehicle.
- the further electrical devices controlled by the other electronics of the motor vehicle can be arranged both inside and outside the internal combustion engine in the motor vehicle.
- the signals to be exchanged between the electronics of the throttle valve assembly and the other electronics can be falsified due to interference pulses, which can lead to faulty and, in extreme cases, no signal transmission at all.
- each cable to be laid in the motor vehicle means additional assembly effort.
- the invention is therefore based on the object of specifying a throttle valve connector of the type mentioned above, the electronics of which can be connected in a particularly simple manner to other electronics of the motor vehicle with a particularly low manufacturing and assembly expenditure. Furthermore, an electronics housing of the type mentioned above is to be specified, which can be arranged in the motor vehicle, in particular in the space of the internal combustion engine, with particularly little production and assembly effort.
- the object is achieved according to the invention by a common arrangement of the first electronics of the throttle valve assembly and second electronics for a number of electrical devices arranged outside the housing in the housing cover of the throttle valve assembly, both the first electronics of the throttle valve assembly and the second electronics of the electrical devices can be contacted via electrical connection means arranged at least partially in the housing cover with the electrical devices arranged outside the housing.
- the invention is based on the consideration that a throttle valve assembly that can be produced with particularly low manufacturing and assembly costs can be connected particularly easily to other electronics of the motor vehicle if the electrical connecting lines from the throttle valve assembly to these other electronics are particularly short.
- the sensor system of the motor vehicle in particular the internal combustion engine, has to be arranged at certain locations in the motor vehicle, for example in order to record specific data such as an oil temperature and / or an oil level, the remaining electronics of the motor vehicle cannot necessarily be arranged in the immediate vicinity of the throttle valve body , The arrangement of the other electronics of the motor vehicle in locations other than that of the throttle valve assembly can lead to errors in the signal transmission.
- both the first electronics for the electric drive and the second electronics for a number of electrical devices of the motor vehicle are arranged directly in the housing cover of the housing of the throttle valve connector.
- both the first and the second electronics can be contacted via electrical connection means arranged in the housing cover with electrical devices arranged outside the housing of the throttle valve assembly.
- the electrical devices are advantageously arranged in an internal combustion engine of a motor vehicle.
- a throttle valve assembly is a conventional component for a motor vehicle, which is often arranged outside the internal combustion engine.
- the other electrical devices of the internal combustion engine of the motor vehicle also need a central unit, via which data from electrical devices of the internal combustion engine can be read in and via the control signals to the electrical see devices of the internal combustion engine can be output.
- a common arrangement of both the first electronics for throttle valve connector and the second electronics for other electrical devices centrally in the housing cover of the throttle valve connector ensures a compact design of the electronics of the motor vehicle, as a result of which the manufacturing and assembly costs for the electronics of the motor vehicle in question are particularly low.
- the electronics for the electrical devices arranged outside the housing of the throttle valve assembly advantageously comprise a control unit, a data acquisition unit and a data storage unit. These three units ensure, in a particularly reliable and particularly simple manner, the acquisition and storage of data from the electrical devices, it being possible for one or more electrical devices to be controlled by means of recorded or stored data.
- the electrical devices are advantageously an ignition device and / or an injection device and / or an oil level measuring device and / or an air mass regulating device. Additionally or alternatively, the electrical devices can also be engine control electronics and / or an electromechanically integrated throttle valve connector. These electrical devices directly control the combustion of the fuel in the internal combustion engine and are therefore directly connected to the position of the throttle valve in the throttle opening of the throttle valve body. Therefore, the readout, control and / or regulating electronics in the throttle valve assembly should be arranged together with the electronics for the throttle valve assembly, particularly in the aforementioned electrical devices.
- the housing cover is advantageously made of plastic, with the electrical connection means at least are partially embedded in the plastic.
- An integration of the electrical connection means in the plastic further reduces the assembly effort of the throttle valve connector, since the electrical connection means integrated in the housing cover only have to be connected to the first and / or second electronics of the housing cover.
- the electrical connection means can be integrated into the housing covers, for example, by injection into the plastic during the manufacture of the housing cover using the injection molding process.
- the housing cover can also be made of a metal-containing plastic or else entirely of metal.
- the housing cover is made of metal, for example aluminum, the electrical connection means must be inserted into the housing cover afterwards and additionally insulated in order to avoid an electrical short circuit to the housing cover. This involves an additional assembly effort, which proves to be uneconomical in the production of the throttle valve assembly.
- Both the first electronics for the throttle valve assembly and the second electronics for the electrical devices arranged outside the housing are advantageously arranged in a region of the housing cover which is delimited by a cover element.
- This cover element can be made of metal, plastic or ceramic.
- the cover element particularly reliably separates the first electronics and the second electronics from the remaining inner region of the housing of the throttle valve assembly. This separation particularly reliably prevents foreign particles from penetrating into the first electronics and the second electronics from the remaining inner region of the housing of the throttle valve assembly.
- the first electronics for the throttle body and the second electronics for the extra Electrical devices arranged half of the housing of the throttle valve assembly are arranged on a common printed circuit board in the housing cover of the housing of the throttle valve assembly.
- the common arrangement of the first electronics and the second electronics on a common printed circuit board requires a particularly low production outlay both for the first electronics and for the second electronics, since these can be brought together on a printed circuit board in one manufacturing process.
- the assembly effort of the throttle valve assembly is simplified since only a single printed circuit board is to be inserted into the housing cover of the housing of the throttle valve assembly.
- the printed circuit board is advantageously arranged on a heat-conducting plate, in particular a metallic plate.
- the arrangement of the printed circuit board on a heat-conducting plate ensures particularly reliably that heat of the electronics which arises during operation of the throttle valve body can be reliably removed from the housing of the throttle valve body via the particularly large area of the heat-conducting plate. With a suitable design of the heat-conducting plate, this reliably prevents excessive heating of the electronics. Excessive heating of the electronics should be avoidable to reliably prevent damage to the electronics or, in extreme cases, complete failure of the electronics. Since the housing cover of the housing of the throttle valve assembly is generally made of plastic and not of metal for reasons of cost, it can usually not dissipate heat.
- the heat-conducting plate ensures in a simple manner that the heat generated by the electronics can be removed from the area of the electronics during operation of the throttle valve assembly.
- the heat-conducting plate in particular a metallic plate, is advantageously fastened with means for fastening both to the housing cover and to the housing body.
- the heat-conducting plate is advantageously fastened with screws, which mainly consist of metal. The heat of the heat-conducting plate can then be transferred via the screws to the housing body, which thus represents a heat sink. As a result, overheating of the electronics arranged in the housing cover of the throttle valve assembly is avoided in a particularly reliable manner.
- the housing body advantageously consists predominantly of metal, in particular aluminum.
- a housing body made of metal dissipates the heat transferred to it by means of the screws particularly well, so that overheating of the electronics is also particularly reliably avoided.
- Aluminum has the advantage that it is particularly easy to process using the injection molding process.
- the electric actuator of the throttle valve shaft is advantageously connected to the first electronics of the throttle valve connector via an electrical plug connection.
- the electrical actuator can be contacted particularly easily with the electronics by means of an electrical plug connection. As a result, the assembly effort for connecting the first electronics to the electric actuator is particularly low.
- a return spring device for returning the throttle valve to an initial position is advantageously arranged in the housing. In the event of a failure of the electric actuator of the throttle valve shaft, this return spring device ensures that the throttle valve can be reset to an initial position even without the electric actuator. This is the starting Position often not the closed position of the throttle valve but a position with a small opening angle of the throttle valve in order to ensure that the driver of the motor vehicle can still reach a repair shop even if the electric actuator of the throttle valve shaft fails.
- a device for detecting the position of the throttle valve shaft is advantageously arranged in the housing. This device for detecting the position of the throttle valve shaft ensures that when the electric drive of the throttle valve shaft is actuated accordingly, it is also brought into a well-defined position. If a signal from the device for detecting the position of the throttle valve shaft indicates that the throttle valve shaft does not assume the desired position despite proper electrical control, an error signal is produced which signals to the driver of the motor vehicle that the accelerator pedal is not functioning properly.
- first electronics for the throttle valve connector and second electronics for a number of electrical devices of the motor vehicle are arranged in the cover element, the first electronics of the throttle valve connector and the second electronics of the electrical devices being arranged via electrical devices
- Connecting means can be connected to the electrical devices of the throttle valve connector and the electrical devices of the motor vehicle, the connecting means being arranged at least partially in the cover element.
- the invention is based on the consideration that the electronics for a motor vehicle can be divided into the electronics of the throttle valve assembly and a second electronics for the other electrical devices of the power unit. vehicle.
- the first electronics for the throttle valve assembly and the second electronics for the large number of electrical devices of the motor vehicle should be arranged close to one another.
- the first electronics and the second electronics can then be arranged particularly close to one another if they are combined in a common electronics module.
- the assembly of the electronics module proves to be particularly simple, since only a single module has to be mounted in the motor vehicle instead of a first electronics for the throttle valve assembly and a second electronics for the large number of electrical devices of the motor vehicle.
- an electronics module that combines the first electronics for the throttle valve assembly with the second electronics of the other electrical devices of the motor vehicle has the advantage that this electronics module can be arranged anywhere in the motor vehicle, and thus the electronics module can also be mounted in so-called blind spots ,
- the electrical devices are advantageously an ignition device and / or an injection device and / or an oil level measuring device and / or an air mass regulating device. These electrical devices are in an operative connection with the position of the throttle valve in the throttle valve connector and should therefore have electronics to avoid transmission errors, which is arranged in the immediate vicinity of the first electronics of the throttle valve connector.
- the housing cover is advantageously made of plastic, the electrical connection means being at least partially embedded in the plastic. If, for example, the housing cover is made of plastic using the injection molding process, the electrical ones can be Embed the lanyard into the plastic during the injection molding process. As a result, the cover element has a particularly low manufacturing cost.
- the first electronics for the throttle valve assembly and the second electronics for the electrical devices of the internal combustion engine are advantageously arranged on a common printed circuit board in the cover element.
- a common circuit board for the first electronics of the throttle valve assembly and the second electronics of the electrical devices of the motor vehicle enables the first electronics and the second electronics to be applied to the circuit board in a single production step, which means that the circuit board is produced with particularly little effort ,
- the printed circuit board is advantageously arranged on a heat-conducting plate, in particular a metallic plate.
- a heat-conducting plate in particular a metallic plate.
- Aluminum is suitable as a metal due to its easy workability. Since, for reasons of cost, the housing cover will generally be made of plastic, the heat-conducting plates ensure that the heat generated during operation of the throttle valve body is transported away from the electronics particularly well via the heat-conducting plate.
- the heat-conducting plate in particular metallic plate, is advantageously fastened with means for fastening both to the cover element and to the base element.
- the means for fastening screws which consist predominantly of metal.
- a heat bridge to the base element can be produced using the screws, and the heat generated by the operation of the electronics can be dissipated particularly easily.
- the base element advantageously consists predominantly of metal, in particular of aluminum.
- the base element guides then the heat of the first electronics and the second electronics transmitted to the base element by the screws is transferred particularly reliably to the surroundings, as a result of which an excessive heating of the first electronics and the second electronics arranged on the printed circuit board is avoided in a particularly reliable manner.
- a central element is created by integrating the electronics required for the motor vehicle and the electronics for the throttle valve assembly into a single common printed circuit board and the arrangement of this printed circuit board in the housing cover of the throttle valve assembly or in the electronics module is the heart of the electronics of the motor vehicle.
- the central element which can be arranged either in the housing of the throttle valve connector or as an electronics module anywhere in the motor vehicle, the entire electronics of the motor vehicle can be arranged in a particularly simple manner in a single assembly step in the motor vehicle.
- the arrangement is particularly flexible when the electronics module is used. Even if the central element is defective, only a single printed circuit board has to be examined for defects and, if necessary, can also be brought back into a functional state by replacement.
- Fig. 3 shows an electronic module.
- the throttle valve assembly 10 according to FIG. 1 is used to supply an air or a fuel / air mixture to a consumer (not shown), for example an injection device of a motor vehicle (also not shown), the fresh gas quantity to be supplied to the consumer being controllable by means of the throttle valve assembly 10.

- the throttle valve shaft 18, the fastening means 20 and the throttle valve 22 are shown in FIG. 1 in an explosive representation.
- a rotation of the throttle valve shaft 18 simultaneously causes the throttle valve 22 arranged on the throttle valve shaft 18 to pivot.
- a pivoting of the throttle valve 22 causes the opening of the throttle opening 16 to be enlarged or reduced. This allows the amount of the flow medium passing through the throttle opening 16 to be adjusted. Movement of the throttle valve 22 thus regulates the throughput of the air or fuel-air mixture through the throttle opening 16 of the throttle valve connector 10.
- the throttle valve shaft 18 can be connected to a rope sheave, not shown, which in turn is connected via a Bowden cable to an adjusting device for a power request.
- the adjusting device can be designed as an accelerator pedal of a motor vehicle, so that this adjusting device is actuated
- the throttle valve 22 can be moved by the driver of the motor vehicle from a position of minimal opening, in particular a closed position, to a position of maximum opening, in particular an open position, in order to thereby control the power output of the motor vehicle.
- the throttle valve shaft 18 of the throttle valve connector 10 shown in FIG. 1 can either be adjusted in a partial area by an actuator and otherwise by means of the accelerator pedal, or the throttle valve 22 can be adjusted by an actuator over the entire adjustment range.
- the mechanical power control for example depressing an accelerator pedal, is converted into an electrical signal. This signal is in turn fed to a control unit, which generates a control signal for the actuator. In these systems, there is no mechanical coupling between the accelerator pedal and the throttle valve 22 in normal operation.
