Definitions

  • the invention relates to a device for controlling the driving speed and regulating the idling speed in motor vehicles with a gasoline engine, having an actuator which adjusts the position of the actuator for vehicle speed control as a function of the position of a setpoint generator and the passage cross section of the area in front of the actuator with the area behind the actuator connecting by-passes determining closing element that is adjustable by a controller-controlled actuator.
  • the idle speed control and the vehicle speed control are carried out with two mutually independent devices. That is, the idle speed control and the vehicle speed control each have their own actuator or closing element, which is each adjustable by its own actuator.
  • Such a structure is very component-based agile and requires a large installation space. This is particularly disadvantageous if the device is installed in a motor vehicle, since there is little installation space available here.
  • a single actuator common to the vehicle speed control and the idle speed control by means of which the closing element for regulating the idle speed can be actuated in a first working area and the actuator of the vehicle speed control can be actuated in a second working area.
  • the common actuator for the vehicle speed control and the idle speed control means that a device is achieved which, in addition to saving installation space, also brings a substantial reduction in cost compared to conventional devices.
  • the actuator in the idle position of the setpoint generator can be controlled by an idle speed electronics and when the setpoint generator is adjusted from its idle position by the setpoint generator, common electronics can be used for both functions, which also leads to a simplification and approval of the device. It is particularly advantageous if the setpoint generator is a transmitter that emits an electrical signal.
  • the closing element for idle speed control and, in turn, the actuator for vehicle speed control can be actuated, it being advantageous if the closing element for idling speed control in its open end position can be brought into operative connection with the closing member for vehicle speed control.
  • This enables in a simple manner that in the idle position of the setpoint generator, only the closing element for idle speed control is actuated by the actuator, while when the setpoint generator is actuated, the actuator actuates the actuator for vehicle speed control via the closing element for idle speed control.
  • Special drive assemblies for transmitting the drive movement are not required.
  • the actuator for vehicle speed control is a throttle valve fixedly arranged on a shaft which can be rotated about its longitudinal axis
  • the shaft is a hollow shaft through which an actuating shaft connected to the closing element for regulating the idling speed is passed, which can be rotated by the actuator is drivable.
  • the hollow shaft can be biased by a spring into the end position corresponding to the rotational position that limits the closed position of the throttle valve. This means that uncontrolled adjustment of the throttle valve is not possible.
  • a coupling is advantageously arranged between the actuating shaft and the hollow shaft, by means of which a rotary movement of the actuating shaft after its rotation can be transmitted from the position corresponding to the closed position of the closing element for idle speed control to the position corresponding to the open position on the hollow shaft.
  • a simple design of such a coupling consists in that a radially directed stop is arranged on the actuating shaft or the hollow shaft, which engages in a groove of the hollow shaft or the actuating shaft, which extends in the circumferential direction with an angle corresponding to the opening cross section of the closing element for idle speed control.
  • the actuating shaft has a recess which extends from the area in front to the area behind the throttle valve and which consists of a through the inner wall of the hollow shaft completely closed position by relative rotation of the actuating shaft and hollow shaft can be brought into overlap with a recess running from the area in front to the area behind the throttle valve.
  • the passage cross section is different in size.
  • the actuating shaft can also be a tubular shaft, the coaxial bore of which can be connected to the area in front of the throttle valve and to the area behind the throttle valve.
  • the hollow shaft and the tubular shaft can each have a radially continuous recess leading to the area in front of or behind the throttle valve, which can be made to overlap by relative rotation of the two shafts about their longitudinal axis, and the coaxial bore of the tubular shaft is connected to the area behind or in front of the throttle valve.
  • This configuration creates a device which, on the one hand due to the elimination of components that have been required since then and on the other hand due to the largely integrated structure of the actuating and closing element, has a compact and compact structure, by means of a common electronics can be controlled and requires little installation space.
  • an intake port 1 is shown at the location of the throttle valve 2 in section.
  • the throttle valve 2 is fixedly connected to a hollow shaft 3 which extends centrally through the intake port 1 and is rotatably supported with its free ends in corresponding bores in the wall of the intake port 1.
  • the throttle valve 2 is prestressed into its closed position by springs 4 and 5, which act on the one free end of the hollow shaft and on the housing 6 of the intake manifold 1.
  • a tubular shaft 7 is arranged coaxially in the hollow shaft 3 and is rotatable about its longitudinal axis relative to the hollow shaft 3. This relative rotation is limited by a radially directed stop 8 fastened to the tubular shaft 7, which protrudes into a groove 9 in the circumferential direction of the hollow shaft 3.
  • the extent and the position of the groove 9 is such that a radially continuous recess 10 of the hollow shaft 3 and a radially continuous recess 11 of the tubular shaft 7 in one contact position of the stop 8 at one end of the groove in complete overlap and in the contact position of the stop on the other Groove ends are in no coverage.
  • the recesses 10 and 11 each lead in the axial bores of the hollow shaft 3 and the tubular shaft 7 to the area of the intake manifold 1 in front of the throttle valve 2, the coaxial bore 12 of the tubular shaft 7 is connected to the area by relative rotation of the two shafts 3 and 7 the throttle valve 2 can be manufactured or locked.
  • a by-pass is by the relative rotation of the shafts 3 and 7 via the recesses 10 and 11 Connection of the area in front of the throttle valve 2 to the area behind the throttle valve 2 can be established, the passage cross section being determined by the degree of coverage of the two recesses 10 and 11.
  • This actuator is controlled by control electronics 15, to which, in addition to the measurement control connections (not shown) for the measured values required for the idling speed, a setpoint generator 16 for controlling the vehicle speed is connected.
  • the actuator 14 is controlled in such a way that, in the idle position of the setpoint generator 16, it operates only in a work area 17 in which the tubular shaft 7 can be rotated.
  • Characterized the 'air flow cross-section of the recesses 10 and 11 is carried out by more or foundedes opening from the region before to the region behind the closed throttle valve 2, an idle speed control of the gasoline engine.
  • the actuator 14 is controlled by the control electronics 15 in such a way that the tubular shaft 7 rotates further beyond its open end position, whereby the hollow shaft 3 rotates from the stop 8 against the force of the springs 4 and 5 becomes. This also rotates the throttle valve 2 and thus opens a direct passage on the intake manifold 1.
  • This working area of the device according to the invention is designated by 18 in FIG.
  • the device in FIGS. 5 and 6 also has a throttle valve 2 which can be driven rotatably in an intake port 1 with a hollow shaft 3.
  • a shaft 7 which can be rotatably driven by an actuator 14 is arranged coaxially and, as in FIGS. 1 to 3, the hollow shaft 3 with the hollow shaft 7, is connected to the hollow shaft 3. This connection is not shown in Figures 5 and 6.
  • the throttle valve 2 has a coaxial opening 19 which can be closed by an idle valve 20 which is firmly connected to the shaft 7 and which has the same size as the coaxial opening 19.
  • the actuator 14 is controlled in such a way that, in the idle position of the setpoint generator, which is also not shown, it only operates in a work area 17, as shown in FIG. Only rotation of the shaft 7 is possible in this working area 17.
  • a Luf t telllisterquerêt is opened or closed at the coaxial opening 19 accordingly. Accordingly, air can flow from the area in front to the area behind the throttle valve 2 and effect idle speed control of the engine.
  • the actuator 14 is activated so that the shaft 7 rotates further in such a way that the shaft 7, as described in FIGS. 1 to 3, comes into operative connection with the hollow shaft 3 and rotates the same.
  • the cross section of the intake manifold 1 closed by the throttle valve 2 is opened to a greater or lesser extent, so that a direct flow of air from the side in front to the side behind the throttle valve 2 is made possible.
  • This work area corresponds to the area designated by 18 in FIG.
