Device for operating the throttle valve "or the handlebar of the injection pump from Brennkraftmas chinen

The! Inflation relates to a device for actuation the throttle valve or the sail rod of the injection pump of internal combustion engines, with one next to the gas lever of Hand-operated control element which, together with an electromagnet, is in a circuit, the armature of which is the Dros selector flap or the control rod adjusted.

In motor vehicles and motor boats, it is known (German Patent 831 195) to provide a twist grip on the steering wheel, by means of which a resistor located in it and lying in an electrical circuit is displaced in the axial direction, on which a contact spring slides. In that of the The battery-powered circuit also includes an electromagnet, through whose armature the throttle valve in the intake port the internal combustion engine is adjusted. Lifting this hand throttle twist grip is provided with a foot throttle that is independent can be operated by the twistgrip.

In contrast, the innovation is that on or on the transmission lever an electrical switch for Opening and closing the circuit is provided and that also the hub for the armature of the electromagnet and the

subsequent transmission elements are designed so that the throttle valve or the control rod when switched on Circuit can be adjusted by a corresponding angle or distance from the closed position to the open position, so that this generates the amount of double-declutching gas required for rapid switching.

The! Inflation was based on the task of the driver of vehicles with non-automatic clutch and transmission on occasions where rapid shifting and simultaneous braking technical support is required, e.g. at sporting events. Braking is part of the sporty driving style a curve, i.e. the driver brakes his car from the highest possible speed before the curve to one permissible speed for the curve. This braking process can extend to the beginning of a curve. At the same time, in many cases (e.g. hairpin bends) it is necessary to shift down to the next lower gear, in order to be able to accelerate to the maximum immediately after the end of the braking process in the curve (power slide). This downshift is done with double-declutching, so that on the one hand the synchronization time is shortened and on the other hand When the clutch is engaged, the braking deceleration does not increase due to the drag torque of the motor, which is the case with a an already initiated emergency braking can lead to the locking of the rear wheels} but this can lead to the car breaking away to lead. The driver is therefore forced to brake with his right foot and, at the end of the braking process, double-declutching at the same time admit. In addition to a favorable arrangement and design of the foot throttle and the brake lever, this requires and their footplates a great skill of the driver and on top of that harbors the great danger that the driver an operator error can occur with his right foot.

The "well-known, initially mentioned device in the form of a hand throttle grip on the steering wheel, is to master the aforementioned driving situation far nieht to the extent suitable as fuel. Once is" forced in the known device the driver in addition to the dedicated service of the steering wheel Susz " at an extreme angle of inclination - to perform other operations with both hands, namely to switch the gearbox with one hand and double-declutching with the other, and on the other hand, he has to make sure that the correct amount of double-declutching is generated .

The control avoids these disadvantages. It bears the one that occurs during the driving situation in question Requirements in full account. The driver can fully concentrate on braking the car with his right foot focus, one hand is free to hold the steering wheel firmly and with the other hand he can shift gears and at the same time simply double-declutch, e.g. with your thumb. The dosage of the amount of intermediate gas is a function of the time in which the driver presses the button. The throttle or control rod position itself is a parameter of this function.

In an embodiment of the control, it is expedient to switch the throttle valve through the Aj
to open automatically.

flap through the armature of the electromagnet to about 45 ° auto-

The control can be used with injection and carburetor engines. With the former, the air throttle is opened and at the same time the control rod of the injection pump is adjusted and, in the case of carburetor engines, the carburetor throttle is pivoted.

In the drawing is an embodiment of the innovation shown. The figure schematically shows the structure of the actuating device.

A push-button switch 12 is mounted on the manual gearshift lever 11, with which an electrical circuit 13 is and can be switched off in that an electromagnet 14 is provided. The anchor 14 * guided in this is if the driver in the idle switch position on switch 12 pushes, tightened and opens via a linkage 15 and 16 and an intermediate shaft 17 brings the air flap 22 to approximately 45 ° line on the armature 14 'acting return spring 18 after opening the switch 12, the throttle valve is in the closed position again. About the intermediate shaft 17 is simultaneously the handlebar 19 driven in the fuel injection pump causes a corresponding increase in the amount of fuel injected compared to the idle amount.

lit 20, the foot throttle is referred to, which has a linkage 21 is coupled to the intermediate shaft 17.
