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 a servomotor 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 object of the invention is to develop a generic throttle valve in such a way that an idle charge control via the servomotor is possible and emergency running properties are maintained.
- a stop actuator is provided which, even when the accelerator pedal is not actuated and the corresponding target value is set, ensures that the stop point of the throttle valve does not completely close the throttle valve, but rather provides an angular range of approximately 10 ° in which the position of the servomotor can be obtained Throttle valve can be regulated.
- 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 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 steep 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.
- the drive lever 22 or, as shown here, the output lever 28 continues to engage a return spring 24, 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 stop spring 32 biases the throttle valve 10 into its open position and thus the extension 16 into its contact position with the driving pin 30 of the actuating element 18. It is essential that the spring 32 has a smaller spring force characteristic than the return spring 24, that is to say it is softer.
- the spring 32 can connect the extension 16 directly to the output lever, but it can also, as shown in the drawing, exert a torque on the axis 12 with one end and be firmly articulated on the motor side with its other end 80.
- 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 and thus limits the pivoting of the actuator 18 in the closed position of the throttle valve 10.
- the stop actuator 54 can be designed as an electric motor or as a pressure cell.
- 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 with the aid of a cable lever 62 which is engaged by the cable 20.
- the actuating lever 64 has a driver 66 which on one Side of the drive lever 22 of the actuator 18 presses and this actuator 18 thus moves 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.
- the servomotor 42 is controlled by electronics. This can be a slip control, for example.
- the controlling electronics also take into account consumption-optimized characteristics, according to which the electric motor can be controlled to open or close the throttle valve. Measures to dampen the load change shock when the throttle valve suddenly opens can also be taken into account here.
- the throttle valve In order to counteract sudden slippage, a load change or also excessive consumption, the throttle valve should be acted on in the direction of its closed position.
- the electric motor 42 is actuated and it actuates a shaft 40 which rotates in the opposite direction to the arrow 100.
- a driver 38 comes into abutment with a radial pin 36 and also rotates the shaft 12 in the direction of arrow 100.
- the extension 16 at the stop point 90 disengages from the driver pin 30 of the actuating element 18, which stresses the spring 32 against its direction of action and the throttle valve around by the elec tronic logic predetermined amount closed.
- 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.
- the swivel part 60 By pulling the accelerator pedal 20, the swivel part 60 is rotated about its axis and presses via the driver 66 in the stop 52 onto the drive lever 22 of the actuating part 18.
- the actuating part 18 is pivoted clockwise in the drawing, with swiveling over the dimension, which is predetermined by the pivoting of the pivoting part 60, is also quite possible, in this case the drive lever 22 would no longer come into contact with the driver 66 of the pivoting part 60 at point 52.
- the return spring 24 holds the drive lever 22 and its extension 50 in contact with the point 52, provided that no further resistances prevent this.
- the pivotal movement of the actuator 18 is transmitted via the driver pin 30 of the actuator 18 to the extension 16 which is connected to the shaft 12 of the throttle valve 10, since the spring 32 presses the extension 16 into contact with the driver pin 30 as long as no further forces Influence throttle valve 10.
- the maximum opening angle of the throttle valve 10 is predetermined, whereas the throttle valve 10 can close against the arrow direction 100 as long as the closing force overcomes the spring constant of the spring 32.
- the closing of the throttle valve between the maximum degree of opening, which is predetermined by the position of the gas cable 20 and the completely closed position tion is set by the servomotor 42.
- the parameters for controlling the motor 42 are determined by correspondingly predetermined parameters stored in memories as well as by vehicle operating parameters (speed, speed, accelerator pedal characteristics and the like) and the values which the sensors 68 and 72 deliver, namely 68 for the actual position of the throttle valve 10 and 72 for the target position of the throttle valve 10, as is predetermined via the load request, which is determined by the accelerator pedal.
- An essential feature of the present invention is the stop actuator 54, which prevents the throttle valve from closing completely due to the mechanical specification. Even if the pivoting part 60 is rotated into its full closed position by an accelerator pedal that is not actuated, the abutment screw 82 against the stop actuator bolt 56 prevents the pivoting lever 18 from being reset to 0 ° by the return spring 24; the stop actuator 54 holds the adjusting lever 18 typically in a position that corresponds to an opening angle of approximately 10 ° of the throttle valve 10.
- the throttle valve is set between 0 and 10 ° solely via the servo motor 42, which is controlled by an idle charge control and thus ensures a constant idle speed.
- the setpoint generator 72 is not held, but can also assume values between 0 and 10 ° as a typical load requirement, in this area, however, the swivel part 60 does not actuate the control part 18, but the power control of the internal combustion engine takes place solely via the setpoint generator 72 and the servomotor 42 instead.
- the lower value for the opening angle set via the stop plate 54 is selected so that the necessary There is scope for the idle charge control.
- the power output of the internal combustion engine can be kept within limits via a further position, whereby on the one hand an emergency operation is possible but on the other hand a dangerous operating state such as sudden, uncontrolled acceleration cannot occur.
- An important area for the application of the invention is the damping of the so-called load change shock. If the accelerator pedal is suddenly depressed, the swivel part 16 and the actuating part 18 are turned suddenly and thus the maximum opening angle is adjusted upward, but the servomotor 42 adjusts the actual opening of the throttle valve 10 with a time delay in order to achieve a softer response behavior, which is not noticeable Reduced performance increases acceleration comfort.
- a speed control system can advantageously be connected to the stop actuator 54.
- the control part 18 is actuated by the cruise control system and specifies the maximum opening angle of the throttle valve 10. Due to the fact that the stop 52 only acts on one side on the drive lever 22 while the drive lever 22 is freely movable to the other side, the pivoting lever 60 is not moved by the pivoting of the actuating part 18 and accordingly the accelerator pedal is not pulled. The speed is then set via the servomotor 42.
