Definitions
- the invention is based on an ignition distributor according to the preamble of claim 1.
- Such an ignition distributor is known from AU-A-509798.
- the insulation shield provided there has the task of avoiding voltage discharges via a shunt by extending the distance between the potentials.
- an intermediate flange is connected between the housing of the ignition distributor and the end cap made of insulating material, which has a central opening through which the rotor can be inserted and connected to the shaft of the ignition distributor.
- This is an ignition distributor of a known type, in which the rotor is only plugged onto the end of the shaft of the distributor. In such a case, the rotor can be dismantled without great effort by removing the end cap from the intermediate flange and pulling off the ignition distributor.
- the object of the invention is to further develop the generic ignition distributor in such a way that a structural unit consisting of a rotor and an aperture-type transmitter element can remain unchanged when assembled or disassembled as a structural unit.
- the ignition distributor according to the invention for solving the specified object has the advantage that a minimum distance between the electrode of the rotor and the signal transmitter is maintained to prevent electrical flashovers and that a very low overall height of the ignition distributor can nevertheless be achieved.
- the rotor and the signal transmitter can remain unchanged as a structural unit during assembly or disassembly of the insulation shield. This has significant advantages, especially when servicing or repairing the distributor.
- FIG. 1 shows the partially sectioned side view of an ignition distributor according to the invention
- FIG. 2 shows an insulation screen for the ignition distributor according to FIG. 1
- FIG. 3 shows an insulation screen that is somewhat modified compared to FIG.
- the ignition distributor shown in Figure 1 is intended for an internal combustion engine, not shown, of a motor vehicle, also not shown.
- This ignition distributor has a base plate 1, which comprises a bearing 2 for a shaft 3 in its central region.
- the shaft 3, which is rotatably mounted in the bearing 2 carries, on its end section protruding from the base plate 1, a coupling piece 4 which is intended for connection to the camshaft, not shown, of the internal combustion engine.
- the inner end portion of the shaft 3 is provided with a flange 5 to which a rotor 6 is screwed.
- the rotor 6 consists of an insulating body 7, from which a distributor finger 8 projects radially.
- a distributor electrode 9 protrudes from the free end of the distributor finger 8 and can be moved past fixed electrodes at a certain distance.
- One of the fixed electrodes is shown and designated 10.
- the fixed electrodes 10 are connected to spark plugs in the cylinders of the internal combustion engine via high-voltage connections 11, not shown.
- ignition voltage pulses are transmitted to the fixed electrodes 10, these ignition pulses being taken from an ignition coil (not shown) and fed via a high-voltage connection 12 and a sliding contact 13 to a contact plate 14 which is in electrical connection with the distributor electrode 9.
- a diaphragm-like sensor element 15 is clamped between the flange 5 and the insulating body 7 and, together with a Hall barrier 16, forms a signal generator 17 that delivers signals for triggering the ignition.
- the rotor 6 and the signal generator 17 are covered by a cap 18 made of insulating material, with which the high-voltage connections 11, 12 form a structural unit.
- the connection cap 18 is fastened to the base plate 1, and in the preferred case screwed, as is indicated by the dash-dotted line 19.
- an insulation screen 20 engages in the space between the rotor 6 and the signal transmitter 17. So that the assembly consisting of the rotor 6 and the signal generator 17 can remain unchanged during assembly and disassembly of the insulation screen 20, this screen 20 is composed of at least two individual parts 21, 22 (FIG. 2), these individual parts 21, 22 having a shell shape . This assembly takes place in such a way that the individual parts are put together. This can be done in such a way that one individual part has labyrinth-shaped grooves on the parting surfaces, which are the cross section of the parting surface of the other Item are adjusted. This also results in good dielectric strength at the parting surfaces.
- a hinge-like connection 24 appears to be particularly suitable for this purpose. This also simplifies the manufacture of the insulation shield 20 in terms of production technology.
- the distributor finger 8 can also be provided with a protruding bead 26 which runs along the distributor finger 8 and lies below the distributor electrode 9.
