Abstract

PURPOSE:To save fuel consumption and reduce harmful exhaust gas by taking out anti-braking energy, converting air into compressed air energy with an air compressor, and recycling the air as auxiliary power with an air pressure motor. CONSTITUTION:Anti-braking energy due to inertia and produced in wheels at the time of braking of an automobile is taken out from a power transmission device with a mechanism operated with interlocking with a brake pedal, and air is compressed with an air compressor 4 to be accumulated in an air tank 9. The air pressure motor 8 is driven with the mechanism operated with interlocking with an acceleration pedal by utilizing this air energy, and output of the air pressure motor 8 is transmitted to wheels via the power transmission device, that is, whenever the brake pedal is operated, the mechanism of the compressor 4 is operated, and the air pressure motor 8 and an auxiliary power output mechanism are operated when the acceleration pedal is operated.

2. Description of the Related Art When a vehicle runs downhill, it does not stop easily, and when it is tried to decelerate or stop while traveling at high speed,
A large braking force is required. This happens when driving,
Inertia (physically, gravity, inertia due to acceleration) is due to anti-braking energy, which is sometimes more powerful and may damage the institutional device, causing a major accident. The method of using this anti-braking energy has been considered for a long time, but it was only used in rubber and springs to store and use it again, downhill and uphill, toy cars and trains. It was However, when the train develops, the train uses a DC motor, so the property of generating electricity when the DC motor is rotated by external force is applied.
At the time of the system, a method is used in which an electric motor is caused to generate power by a reverse load of anti-braking energy, and the generated power is reversely transmitted by a transmission line. In automobiles, a method of extracting this anti-braking energy as electric energy by a generator, storing it in a storage battery and using it as auxiliary power by an electric motor when necessary is possible. Since the volume and weight are large, it is difficult to implement, and it is not easy to install the device especially for small cars.

[0003]

[Problems to be Solved by the Invention]

I. The anti-braking energy due to the inertia of the car can be easily extracted. B. Can convert energy easily and can store a relatively large amount. C. Being able to easily output and convert energy again. D. Easy to operate.

[0004]

[Means for Solving the Problems]

I. It can be easily installed on the power transmission device of a car. B. Since an air compressor and an air tank are used and the material of the air tank is a light alloy and it can be installed under the seat, under the floor, etc., it is possible to have a relatively lightweight and large capacity. C. The pneumatic motor is used and the output can be easily adjusted by the control valve. D. Since the mechanism is linked to the brake petal and accelerator petal, the operation is exactly the same as the non-device vehicle.

[0005]

[Operation] Each time the brake petal is operated, the compressor mechanism is activated, and when the accelerator petal is operated, the pneumatic motor and the auxiliary power output mechanism are activated.

EXAMPLE An energy output pulley (2) or a gear is fixed on a propeller shaft (1) of a power transmission device of an automobile using an internal combustion engine as a prime mover, and an electromagnetic clutch (3) and pressure are fixed by a belt or a gear. Connect the air compressor (4) with valve. Similarly, fix the pulley (5) or gear for the auxiliary power output mechanism on the propeller shaft,
A pneumatic motor (8) having an electromagnetic clutch (6), a control valve, and an air opening / closing valve (7) is connected by a belt or a gear. Connect the air piping from the compressor to the air tank (9) and from the air tank to the pneumatic motor. In operation, the operation of the energy extraction mechanism depends on the brake petals. When the brake petal is stepped on while the vehicle is running, the switch (10) provided near the brake petal support shaft becomes "on", and the current from the power switch (11) flows to the electromagnetic clutch of the air compressor to connect the clutch. The rotation of the pro-hera shaft rotates the compressor and compresses the air. The compressed air passes through the piping and accumulates in the air tank. When you release your foot from the brake petal, the electromagnetic clutch disengages and the compressor stops. The operation of the auxiliary power output mechanism is automatically activated by the accelerator pedal. By pressing the accelerator pedal lightly, a switch (1
2) becomes "ON" and the electromagnetic clutch of the pneumatic motor is connected, and at the same time, the electromagnetic air opening / closing valve (7) attached to the control valve is opened and the motor rotates. The accelerator petal is a mechanism that is linked to the control valve of the pneumatic motor by a link mechanism and is linked to the output of the prime mover to adjust the output. By strongly stepping on the accelerator pedal, the control valve opens wide, and the output of the pneumatic motor also increases as the output of the prime mover increases. When you release your foot from the accelerator petal, the motor clutch disengages, the air on-off valve closes, and the motor stops rotating. The pressure valve of the air compressor is provided so as to apply a constant load to the compressor regardless of the air pressure in the air tank and to obtain a braking effect similar to that of engine braking. A pressure detection switch (13), a safety valve, and an excess air release valve are installed in the air tank so that the motor does not operate below a certain pressure. The electric circuit has a parking brake switch (14) and a back range switch (15).
The structure is such that the entire mechanism does not operate when parking or moving backward.

[0007]

According to the present invention, a relatively large amount of anti-braking energy due to inertia of a vehicle is compressed by an air compressor to be converted into air energy, which is reused as an auxiliary power by a pneumatic motor. However, relatively simple and reliable output can be obtained, fuel efficiency can be saved, harmful exhaust gas can be reduced, and the braking effect due to the load of the compressor can improve driving safety.
