Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an accelerator cable disconnecting device developed for the purpose of preventing an accident due to a pedal depression between a brake pedal and an accelerator pedal.

[0002]

[Prior art]

 In new news, etc., it is often the case that a large accident occurs due to the difference between the brake pedal and the accelerator pedal. There is no means other than rational judgment to prevent the difference between the two functions, braking and acceleration. Even if a high-level preventive measure by incorporating a computer is considered, it must be expensive and complicated, and we have not heard of any cases where such measures have been implemented.

[0003]

[Problems to be solved by the device]

 The present invention is a mechanism that is not complicated enough to be implemented, and that a mechanism that does not cause acceleration even if the accelerator pedal is misstepped when there is a danger of stepping on the brake pedal, and in a panic.

[0004]

[Means for Solving the Problems]

 As a result of studying the above-mentioned problems, a device for interposing an accelerator cable between an automobile engine and an accelerator pedal, in which a partition wall 3 is provided at an intermediate portion of a cylinder 2 and one engine side is provided with a packing 4 for a piston shaft 1b. The oil pump chamber 5 is separated by the oil pump chamber 5. The oil pump chamber 5 communicates with the oil tank 12 with the check valve 11 interposed therebetween, and the other accelerator pedal side is at the tip of the piston shaft 1b protruding beyond the partition wall. An accelerator cable breaker has been developed which is characterized in that the attraction plate 6 is provided, and the magnet plate 7 is connected to the accelerator pedal side cable 8a facing the attraction plate 6 and is provided on the shaft 1a having the biasing spring 9.

[0005]

With such a structure, when the accelerator pedal is operated in a normal state, the suction plate 6 and the magnet plate 7 are in close contact with each other, and the piston shaft 1b and the packing 4 provided thereon are After moving in the cylinder, oil flows from the oil pump chamber 5 in the cylinder into the oil tank 12 through the check valve 11. The reverse is also possible. When the operating force of the accelerator decreases, the magnet disc 7 moves backward together with the adsorption disc 6 by the biasing spring 9, and the oil also returns from the oil tank 12 into the cylinder.

However, if the accelerator pedal is accidentally depressed with a sudden and strong force such as sudden braking, the check valve is closed and the oil cannot flow into the oil tank 12. Therefore, the packing 4 and the suction plate 6 coaxial with the packing 4 stop in the cylinder. Therefore, even if the accelerator pedal is further depressed, the suction plate 6 and the magnet plate 7 are separated from each other, and the engine side. The operating force (tension) of the cable becomes zero and the engine brake is applied to prevent runaway.

【Example】

 FIG. 1 is a sectional view of the device under consideration when the accelerator pedal is not depressed when the vehicle is stopped or idling. This device is located in the middle of the accelerator cable between the automobile engine and the accelerator pedal. A partition wall 3 is provided at an intermediate portion of a cylinder 2 supported by a bracket 10 on the vehicle body to form an oil pump chamber 5 which is separated from one engine side by a packing 4. The oil pump chamber 5 communicates with an oil tank 12 with a check valve 11 interposed therebetween. At the end of the cylinder 2 on the engine side, there is an air passage hole 13 through which air flows in and out as the packing 4 moves. The check valve 11 has a structure in which a valve 11a capable of closing the valve seat 5b around the oil passage hole 5a between the oil pump chamber 5 and the oil tank 12 is biased to a normally open state by a spring 11b. The check valve can be adjusted by the adjuster screw 11c holding the spring 11b on the oil tank side.

The shaft 1b provided with the packing 4 extends through the partition wall 3 of the cylinder to reach the other accelerator pedal side, and a metal suction plate 6 is provided at the tip thereof. A magnet plate 7 is provided so as to face the attraction plate 6 so as to move back and forth in the cylinder by means of a shaft 1a. The shaft 1a is connected to the accelerator pedal side cable 8a, and the biasing spring 9 is externally attached to keep the magnet board 7 always in the returning direction.

FIG. 2 shows a state in which the accelerator pedal is operated in a normal state. When the accelerator pedal side cable 8a is pulled, it is pulled by the suction board 6 and the magnet board 7 so that the shaft 1b and the packing 4 provided thereon also move in the cylinder. Along with that, oil is flowing from the oil pump chamber 5 in the cylinder through the check valve 11 into the oil tank 12. Of course, the reverse is also possible, and when the operating force of the accelerator decreases, the magnet disc 7 moves backward together with the adsorption disc 6 by the biasing spring 9, and the oil also returns from the oil tank 12 into the cylinder.

FIG. 3 is an enlarged view showing a state in which the accelerator pedal is accidentally depressed when the brake must be depressed. Since the shaft 1a connected to the accelerator pedal side cable 8a is pulled with a sudden and strong force such as stepping on the brake, the check valve 11 is closed due to the rapid movement of the packing 4 in the cylinder, and as a result, the oil pump The oil in the pump chamber 5 cannot flow into the oil tank 12. As a result, the suction plate 6 at the tip of the piston shaft 1b becomes stuck in the cylinder, and when the accelerator pedal is further depressed, the suction plate 6 and the magnet plate 7 are separated as shown in the figure. That is, the tension of the shaft 1b connected to the cable on the engine side becomes zero, which prevents runaway.

[0011]

[Effect of device]

 As described above, the present invention can prevent a runaway due to a wrong step of the brakes and can achieve the safety of the vehicle.
