Definitions

  • the invention relates to a throttle valve for an internal combustion engine according to the preamble of claim 1.
  • Such a throttle valve is described in DE-A 37 11 779.
  • This known throttle valve is controlled by an actuator between the fully closed position (0 ° position) and the maximum open position, which is specified by a mechanical encoder.
  • the mechanical transmitter specifies the full closed position of the throttle valve, so the safety of a mechanical accelerator pedal is achieved when the possibilities of regulating an electronic accelerator pedal are exercised.
  • the maximum stop point for the opening of the throttle valve is mechanically predetermined, while the electronically controlled Servomotor keeps the opening angle of the throttle valve smaller than mechanically specified due to an association between the opening angle and the accelerator pedal position.
  • the stop pin assigned to the throttle valve an extension of the shaft that supports the throttle valve, can only come into contact with the stop point when emergency operation is activated. According to the invention it is provided that when the system is reached the parts are mechanically connected to one another, for example locked, and then the throttle valve is moved directly mechanically by the cable and is no longer set by the servomotor.
  • a spring is provided as an example of the snap-in connection mentioned above, but any other snap-in connections from the prior art are also possible.
  • a connection via magnets is also conceivable.
  • the first stop plate is known from EP-A 389649 mentioned above. When pressurized, it limits the mechanical resetting of the throttle valve to approximately 10-11 °, corresponding to a mixture throughput of approximately 60 kg / h. In the range between 0 and 11 °, the throttle valve is controlled solely by the servomotor. B. an idle charge control possible.
  • a second stop actuator which in the normal case has retracted its stop when pressure is applied and thus does not define a stop, ie it has no task.
  • the first stop actuator is deactivated and retracted due to a lack of pressure, so that the throttle valve is mechanical can also close below the 10-11 °, while the second stop actuator extends due to a lack of pressure and limits the closing angle of the throttle valve to an emergency running gap of approximately 5 °, corresponding to a pressure rate of approximately 15 kg / h. Mechanical idling is thus maintained, and at the same time there is contact and locking of the parts of the attachment point at this point.
  • the reference numeral 10 denotes a throttle valve which is installed in an intake manifold of an internal combustion engine, which in the illustration provided here would have to run vertically.
  • the throttle valve 10 is shown in the open state, it can be pivoted about a shaft 12, wherein a pivoting in the direction of arrow 100 would bring the throttle valve 10 into its open position.
  • the shaft 12 is bent at one end at an angle to a radial extension 16 which is positively connected in terms of movement to the throttle valve 10, in the continuation of its axis 14 the shaft of an actuating element 18 is provided coaxially, which has a drive lever 22 and an output lever 28.
  • the pivoting of the actuating part 18 is set via the drive lever 22, the output lever 28 transmits this pivoting in a manner to be described to the extension 16 which is positively connected in terms of movement to the throttle valve 10.
  • a return spring 24 also acts, the other end of which is articulated at point 26 on the motor side, this return spring 24, which is designed as a double spring for safety reasons, acts on the throttle valve 10 in its closed position.
  • the output lever 28 has a driving pin 30 which runs parallel to the axis 14 and is in contact with the extension 16.
  • a servomotor 42 is provided for regulating or controlling the throttle valve opening.
  • This servomotor 42 is controlled by electronics. This can be a slip control, for example.
  • the driving electronics further takes into account consumption-optimized characteristic curves and thus keeps the opening angle of the throttle valve 10 smaller than is mechanically possible, as will be explained in detail in connection with FIG. 2.
  • the electric motor 42 is activated. It actuates a shaft 40 which rotates in the opposite direction of the arrow 100.
  • a driver 38 is in abutment with a radial pin 36 and also rotates the shaft 12 in the direction of arrow 100.
  • the radial pin 36 and the driver 38 are connected to one another via a spring 32, which in normal operation contacts the pin 36 with the driver 38 holds.
  • the spring 32 can expand accordingly; this emergency operation is explained further below.
  • the spring 32 has a smaller spring force characteristic than the return spring 24, that is, it is softer.
  • An extension 50 of the output lever 28 of the actuator 18 has at its end 58 an adjustable stop screw 82, which comes into contact with a stop actuator bolt 56 of a stop actuator 54 during normal operation when the accelerator pedal is not actuated and thus limits the pivoting of the actuating part 18 in the closing direction of the throttle valve 10.
  • the stop actuator 54 can be designed as an electric motor or as a pressure can, its bottom 56 is extended when activated.
  • the actuating lever 18 is rotated in the direction of the open position of the throttle valve 10, that is to say in the direction of rotation of the arrow 100, by a pivot part 60 which can be pivoted by actuating a cable 20 which is connected to an accelerator pedal (not shown).
  • the shaft 12 of the throttle valve 10 the axis of rotation of the adjusting part 18 and the axis of rotation of the pivoting part 60 are aligned coaxially with one another.
  • a counter arm which is designed as an actuating lever 64, can be pivoted about this axis 14 with the aid of a pulley 62 which is engaged by the cable 20.
  • the actuating lever 64 has a driver 66 which presses on one side of the drive lever 22 of the actuating part 18 and thus moves this actuating part 18 in the direction of the open position.
  • a return spring 70 is provided which ensures that when the accelerator pedal is not actuated and thus when the cable 20 is loose, the pivoting part 60 is moved into its zero position.
  • a setpoint generator 72 which, as a sensor, emits an electrical signal that is representative of the load request that is generated by the driver when the accelerator pedal is actuated.
  • An actual value transmitter 68 which determines the actual degree of closure of the throttle valve 10, is assigned to either the shaft 12 or the shaft 40 and provides a value for the actual degree of throttle valve opening.
  • a disadvantage of this arrangement is that in emergency operation the servomotor must work against a strong return spring that maintains the system between the extension 16 and the driving pin 30.
  • the extension 16 is connected at one end to an extension arm 106, which comes into contact with the extended setting pin 104 of a second stop actuator 102.
  • the bolt 56 of the stop actuator 54 is extended and the bolt 104 of the stop actuator 102 is retracted, for example by hydraulic control.
  • the bolt 56 of the stop actuator 54 is retracted and the bolt 104 of the stop actuator 102 is extended.
  • extension 16 On its other side at the attachment point 90, the extension 16 carries a detent spring 101 which locks with the driver pin 30 when it comes into contact with the extension 16. Thus, extension 16 and driver pin 30 are connected to each other.
  • the first stop actuator 54 is deactivated, so that the output lever 28 could move to a position that corresponds to a throttle valve opening angle of 0 °.
  • the servomotor 42 is brought into its open position, it is not supplied with current.
  • the throttle valve 10 is now closed mechanically by releasing the accelerator pedal and moving the cable 20 and actuating the spring 24, the extension 16 and the driving pin 30 come into contact with one another at the attachment point 90, and the detent spring 101 wedges the two components.
  • the throttle valve is now pivoted purely mechanically through the now rigid connection in the attachment point 90 in the range between approximately 5 ° throttle valve angle (caused by the stop divider 102) and 90 ° throttle valve shaft angle (with the accelerator pedal fully depressed), the servomotor is no longer active.
  • the servomotor 42 sets the throttle valve 10 as a function of parameters between 0 ° and the angle specified by ⁇ 10.
  • the respective specifications apply to normal operation, that is to say extended stop plate 54 and retracted stop plate 102.
  • the output lever 28 is lifted off the bolt 56, the setting angle setting via the rope pulley 62, which is recorded via the setpoint potentiometer 72, corresponds to the angular position of the intermediate part 18. According to the predetermined characteristic curves, the actual position of the throttle valve 10 remains below this Angular value.
  • the actual opening angle ⁇ 10 of the throttle valve is in the range below 11 ° and is predetermined by the electronics.
