Definitions

the invention relates to a throttle valve device according to the preamble of patent claim 1.
Such a device is published in DE-A1-38 11 892 and has an electric motor drive there, which enables the throttle valve to be adjusted independently of the accelerator pedal position set by the engine operator.
the electric motor is driven by an electric motor, which acts on the throttle valve shaft via a gear.
an emergency driving device in which an electric clutch connects the throttle valve shaft directly to the accelerator pedal, projecting claws should snap into corresponding recesses.
This device has the disadvantages that the electric clutch has movable electrical connection lines and, depending on how the claws engage, the accelerator pedal can be incorrectly assigned to the throttle valve position.
the object of the invention is to design a specified device such that static electrical connecting lines can be used and the accelerator pedal is precisely assigned to the throttle valve position when there is an emergency operation situation.
FIG. 1 This shows schematically a throttle valve device 1 according to the invention with walls of a housing 2 and a throttle valve 5 fastened on a throttle valve shaft 3 and arranged in an air intake duct 4.
a potentiometer 6 and a throttle lever 7 are fastened to the throttle valve shaft 3, with an electric motor 8 on this attacks, either directly or via a gear.
An actuating lever 9 is connected to an accelerator pedal 10 and can be adjusted in accordance with an engine operator. When the accelerator pedal is released, the actuating lever 9 bears under the force of a return spring 11 against an idle stop formed by an adjusting screw 12.
the position of the actuating lever 9 is detected by a potentiometer 13 connected to the lever 9.
An electrical magnetic actuator 14 is connected to the housing 2 by a coil system 15 and has an actuator 16 that has two lever projections 17, 18.
a lever extension 17 is connected to the throttle lever 7 in such a way that a clamp element 22 formed from two elements 19, 20 and a spring 21 holding together both detects and aligns them with one another. The same clamp element 22 detects the other lever shoulder 18 and the actuating lever 9.
the actuator 16 When the magnetic actuator 14 is activated, the actuator 16 is held in a predetermined position, so that when the actuating lever 9 and also the throttle lever 7 are actuated, the clamp element 22 by adjusting an element 19, 20 is expanded against the force of the spring 21, this element 19, 20 then lifting off the lever shoulder 17, 18 and the other being supported on the lever shoulder 17, 18, the throttle lever 7 or the actuating lever 9 being supported by the supporting element 19 , 20 takes off.
the potentiometers 6, 13 and the electric motor 8 are connected to an electronic control unit via electrical lines (not shown).
the actuating lever 9 is not actuated so that it bears against the adjusting screw 12.
the control unit is supplied with operating values for engine load, speed, temperature, etc. and is processed in the control unit according to predetermined programs in connection with the potentiometer signals to control signals for the electric motor 8.
the throttle lever 7 is pivoted to the right by the electric motor 8 until a throttle valve opening indicated by the potentiometer 6 on the throttle valve shaft 3 is reached.
the throttle lever 7 When the internal combustion engine is started, the throttle lever 7 is reset with increasing engine temperature, so that speed control can take place.
the potentiometer 6 reports to the control device that a throttle valve opening is desired. This predetermined throttle valve opening is only achieved when the throttle lever 7 by the electric motor 8 is lagged to the right in time lag.
This adjustment of the throttle lever 7 following the actuating lever 9 is also provided for the closing process of the throttle valve 5 (closing damping).
the throttle valve device 1 With the throttle valve device 1 according to the invention, a filling control / regulation has become possible which has no effect on the accelerator pedal operated by the engine operator. It has become possible to perform opening and closing damping. In addition, this has the advantage that the throttle valve can be actuated in its entire adjustment range and the electric motor itself can always correct the throttle valve position in the respective relative position, even in the case of a speed control.
the device has static electrical lines. A position control of the throttle lever 7 is possible by the arrangement of the second potentiometer 13. The device can be created with simple design effort and forms a compact design.
the function of the device according to the invention can be compared with a known system for electrical / electronic control of the throttle valve, in which the accelerator pedal and the throttle valve actuation are only connected via electrical lines, with this system having considerable safety potential compared to this system, since the proven mechanical actuation is still present.
the electric motor 8 is switched off by the control electronics and at the same time the energization of the magnetic actuator.
the actuator can be connected directly to the magnetic armature of the magnetic actuator 14 or locked by a locking element 23 (indicated by dash-dotted lines) connected to the magnetic armature.
