Definitions
- the invention relates to a direct drive for a throttle valve shaft in a throttle valve assembly.
- Direct drives are known. As a rule, this involves the arrangement of a coil which is supplied with electrical current and a rotor which is arranged in its area of action and which is provided with permanent magnets and is set into a rotary movement by the coil induction.
- the invention has for its object to provide a direct drive for a throttle valve shaft in a throttle valve assembly, with which a position detection of the throttle valve is continuously possible and which only requires a relatively small amount of space.
- a direct drive for a throttle valve shaft in a throttle valve connector which consists of a coil and a rotor arranged directly next to the coil, in which the rotor consists of a steel ring, in which a first inner magnetic shell and one inside the second inner magnetic shell lie opposite one another and on the outside there is a first outer magnetic shell and a second outer magnetic shell lying opposite one another and 0 in which the steel ring is connected to the throttle valve shaft at its end facing the throttle valve, and in the region of the one facing away from the throttle valve In the middle of the steel ring a sensor for position detection of the Throttle valve is arranged. The rotor is located right next to the coil.
- the inner circumferential surface of the steel ring, which is connected to the throttle valve shaft consists of a non-magnetic material is particularly advantageous.
- An intermediate layer made of plastic can be provided.
- commercially available AMR sensors anisotropy magnetoresistor sensors
- the first inner magnetic shell and the second inner magnetic shell serve for position detection with respect to the
- the first outer magnetic shell and the second outer magnetic shell serve to drive the rotor via the coil. It has surprisingly been found that with the direct drive for a throttle valve shaft in a throttle valve connector, position detection of the position of the throttle valve in the throttle valve connector is possible in a relatively simple manner, with only relatively little installation space being required, since the sensor is arranged over a partial area of the valve Coil is realized.
- the arrangement of the steel ring has the advantage that the magnetic fields, caused by the first inner magnetic shell and the second inner magnetic shell on the one hand and the first outer magnetic shell and the second outer magnetic shell on the other hand, do not adversely affect one another, so that the sensor provides precise information about the actual position of the throttle valve in the throttle valve connector is supplied, which can then be passed on to the control units. Is to it is advantageously not necessary to arrange the sensor outside the rotor of the direct drive in order to detect an accurate detection of the position of the throttle valve in the throttle valve connector, which would require a larger installation space.
- a preferred embodiment of the invention consists in that the first inner magnetic shell and the first outer magnetic shell and the second inner magnetic shell and the second outer magnetic shell are each arranged parallel to one another on the same half of the steel ring. This advantageously facilitates the manufacture of the direct drive rotor for a throttle valve shaft.
- the first inner magnetic shell and the first outer magnetic shell and the second inner magnetic shell and the second outer magnetic shell each have the same magnetic polarity. In this way, the course of the magnetic lines in the area of the steel ring can be optimized, as a result of which the quality of the information that is fed to the sensor can also be optimized.
- a further preferred embodiment of the invention consists in that the steel ring has an annular groove in the region of the end facing away from the throttle valve, in which the first inner magnetic shell and the second inner magnetic shell rest on the steel ring.
- the first inner magnetic shell and the second inner magnetic shell can be securely fixed in the steel ring in a relatively simple manner, at the same time preventing the first inner magnetic shell and the second inner magnetic shell from extending over the entire width of the steel ring extend. It is advantageous that the first inner magnetic shell and the second inner magnetic shell are only in the area of the sensor, and thus the smallest disruptive influences on the actual drive are avoided.
- a further embodiment of the invention consists in that the first inner magnetic shell or the second inner magnetic shell are arranged at a distance a of 1 mm to 3 mm from the stop of the steel ring delimiting the annular groove. In this way, the shielding effect of the steel ring can be optimized, which has an advantageous effect on the position detection of the throttle valve.
- Magnetic shell or the first outer magnetic shell and the second outer magnetic shell each arranged as a single part.
- the item thus acts as a ring magnet. This facilitates the manufacture of the direct drive for a throttle valve shaft, since the number of individual parts that are in the
- Fig. 2 shows the cross section of the direct drive for a throttle valve shaft in a throttle valve assembly according to
- 3 a), b) shows the direct drive for a throttle valve shaft in a throttle valve connector in a three-dimensional form in an exploded view.
- Fig. 1 the direct drive for a throttle valve shaft in a throttle valve neck is shown in side view and in cross section according to section A-A. It consists of a coil 1 and a rotor 2 arranged directly next to the coil 1, the rotor 2 consisting of a steel ring 3, in which a first inner magnetic shell 5a and a second inner magnetic shell 5b lie opposite one another. On the outside of the steel ring 3, a first outer magnetic shell 4a and a second outer magnetic shell 4b are arranged opposite one another, which serve to generate the rotary movement via the coil 1.
- the steel ring 3 is connected to the throttle valve shaft (not shown) and has a sensor in the center (not shown) for detecting the position of the throttle valve. It is clear from FIG. 1 b) that the width of the coil 1 extends over the entire width of the rotor 2.
- FIG. 2 the direct drive for a throttle valve shaft in a throttle valve neck according to section AA in FIG. 1 is shown enlarged.
- the steel ring 3 has a sensor (not shown) in the center 6 of the end 3 ′′ facing away from the throttle valve (not shown) for detecting the position of the throttle valve.
- the steel ring 3 In the region 6 of the end 3 ′′ facing away from the throttle valve, the steel ring 3 has an annular groove 3 ′′ ′′, in which the first inner magnetic shell 5 a and the second inner magnetic shell 5 b rest on the steel ring 3.
- the first inner magnetic shell 5a and the second inner magnetic shell 5b are at a distance a of 1 mm to 3 mm from that which defines the annular groove 3 ''' Stop 3 * of the steel ring 3 arranged.
- the steel ring 3 is connected at its end 3 ′ facing the throttle valve to the throttle valve shaft (not shown).
- the first inner magnetic shell 5a and the second inner magnetic shell 5b are arranged opposite one another in the steel ring 3 in the direction of the arrow.
- the sensor 10 is arranged in the area 6 of the end 3 ′ 1 (not shown) of the steel ring 3 facing away from the throttle valve 9 in the center for position detection of the throttle valve 9.
- the sensor 10 is a commercially available position sensor, for example AMR sensors
- the steel ring 3 has a shielding effect and prevents mutual negative influence of the first inner magnetic shell 5a and the second inner magnetic shell 5b on the one hand and the first outer magnetic shell 4a and the second outer magnetic shell 4b on the other hand.
- the first inner magnetic shell 5a and the second inner magnetic shell 5b or the first outer magnetic shell 4a and the second outer magnetic shell 4b can also be manufactured as individual parts.
- the arrangement of the sensor 10 in the center of the interior of the rotor 2 is particularly advantageous, as a result of which the required installation space can be minimized.
