Definitions

  • the invention relates to a device according to the preamble of patent claim 1.
  • the invention has for its object to provide a device of the type mentioned, which ensures effective slip prevention in all cases in which undesirable high slip occurs. An intervention in the transmission path between the power control element and the power control element should be avoided.
  • the driver Due to the direct effect of the stop on the power control element, even if the motor vehicle is accelerated negatively, the driver himself receives information about an inadmissible slip of the driven wheels which may occur. Since the stop indicates the point at which the slip just has the maximum permissible value, the driver can then set the power output of the internal combustion engine to the extremely possible value in each traffic situation. The motor vehicle can thus always be operated with the optimal propulsion or with the optimal deceleration.
  • the design of the invention can be different.
  • the stop can also be actuated hydraulically. This has the advantage that relatively high forces can be transmitted to the power control element without any problems even with long-term use.
  • the power control element can be adjusted both in the direction of a reduction in power and an increase in power of the internal combustion engine. This is achieved, for example, with the aid of a double-acting cylinder that is non-positively connected to the power control element.
  • the stop can also be overridden. In terms of design, this can be achieved, for example, with the aid of a resilient mounting of the stop, which allows the stop to be overpressed.
  • the device shown in FIG. 1 contains, as an essential element, a stop 1 for the accelerator pedal 2 of a schematically shown internal combustion engine 3, which has a control element in the form of a throttle valve 4.
  • a schematically illustrated transmission linkage 5 converts the position of the accelerator pedal 2 serving as a power control element into a corresponding position of the throttle valve 4.
  • the stop 1 consists of a bellows 6, which is connected via a valve 7 and a feed line 8 to a reservoir 9 for hydraulic oil.
  • the memory 9 is part of a cylinder 10 in which a piston 11 can be displaced on both sides by a drive, not shown.
  • the drive for the piston 11 and the valve 7 are controlled as a function of the slip of the driven wheels of the motor vehicle.
  • the speed of a non-driven wheel 13, for example on the front axle and a driven wheel 14 on the rear axle is compared in a comparator 12 and control signals for the drive of the piston 11 and the valve 7 are output at a predetermined speed difference that is typical of a slip.
  • the piston 11 is moved to the right in the figure.
  • the bellows 6 is filled via the valve 7 in the position shown and adjusts the accelerator pedal 2, which is deflected against the force of a conventional return spring 15, in the direction in which the throttle valve 4 reduces the performance of the internal combustion engine 3. This adjustment takes place until the slip is below its limit value.
  • the comparator 12 then controls the valve 7 to the other position and switches the drive of the piston 11 so that the bellows 6 is now emptied under its own spring action and the piston 11 is moved in the opposite direction.
  • the throttle valve 4 can now be adjusted in the sense of increasing the power of the internal combustion engine 3. If excessive slip now occurs again, the process described above is triggered again and the accelerator pedal 2 is reset using the stop 1.
  • the device according to FIG. 2 is only modified in two ways compared to that of FIG. 1.
  • the stop 1 ' only acts on the accelerator pedal with the aid of a piston, i. H. the self-restoring force is missing.
  • this can be achieved by controlling the drive for the piston 11 in the figure to the left following the reduction of the slip.
  • the piston 16 is mounted elastically.
  • a kick-down spring 17 is used for this purpose, which exerts a smaller force on the accelerator pedal 2 than the piston of the cylinder 16. This makes it possible to override the stop 1 '.
  • FIG. 3 shows a device in which slip limitation is ensured even in overrun mode.
  • a double-acting cylinder 19, non-positively connected to the accelerator pedal 2 is used, with the aid of which a defined movement of the accelerator pedal can be generated both in the sense of reducing the power of the internal combustion engine when the drive torque is too great and in the sense of increasing the power when the brake torque is too great.
  • the cylinder 19 is controlled with the aid of a valve 20.
  • the piston 11 is driven in such a way that a force is applied to it when an impermissible slip occurs. Depending on the cause of the slippage, this force is transmitted to one or the other side of the piston 21 in the cylinder 19.
