    Auxiliary Rotating Brake System
    The present invention relates to a brake device of a vehicle, and more particularly, by using the air pressure of the air conditioner compressor to perform a braking action in particular at high speeds, thereby reducing the initial braking time and thus improving the braking performance. A secondary rotating brake device.
    The braking device of a vehicle is a very important device used to decelerate or stop a driving car and maintain a parking state at the same time. Usually, the brake device is used to convert the kinetic energy of the car into thermal energy using a friction force to brake.
    The braking device includes a foot brake operated by the driver's foot and a hand brake operated by hand.
    Foot brakes are used during driving and use wheel brakes to brake the wheels directly.
    Hand brakes are often used for parking purposes or for emergency use in the event of a brake failure.
    As the operating mechanism, there are a mechanical type using a rod or a wire and a hydraulic type using a hydraulic pressure. In addition, there are a servo brake using a negative pressure or compressed air of an engine, and an air brake using only compressed air.
    The hydraulic brake is based on the principle of Pascal, which is a master cylinder that generates hydraulic pressure including the brake body, a wheel cylinder that receives the hydraulic pressure and presses the brake shoe to the drum to generate braking force, and connects these two parts to form a flow path. It consists of brake pipe and hose.
    The brake main body receives a hydraulic pressure from the master cylinder to generate a braking force. The brake main body is divided into a drum brake and a disk brake.
    The drum brake consists of a wheel, a drum mounted on the wheel, a wheel cylinder installed in the drum, a brake shoe, lining, a return spring, a brake pipe and a brake hose, and the like. There are ring shoe type and two leading shoe type.
    The brake drum rotates at high speed together with the wheel wheels and generates braking force under friction of the shoe.
    The wheel cylinder receives hydraulic pressure from the master cylinder and pushes the brake shoe to the drum.
    The brake shoe is pushed to the left and right by receiving the hydraulic pressure of the wheel cylinder to open and press the brake drum, has a T-shaped cross section and is installed on the back plate pressed steel sheet, but the cam for adjusting the gap between the drum and the shoe Some are installed on this back plate.
    Brake lining is attached to the surface of the brake shoe in contact with the drum, there are woven lining and mold lining by friction material to increase the friction force with the brake drum.
    The return spring returns the open brake shoe when the brake pedal is released.
    The brake pipe introduces the brake fluid from the master cylinder to the wheel cylinder. The brake hose connects the pipe mounted on the frame with the axle or wheel, and is also called a flexible hose.
    When the brake pedal is pressed in such a configuration, the piston in the master cylinder presses the brake fluid to the wheel cylinder, and the wheel cylinder receives the hydraulic pressure and presses the piston to the left and right to squeeze the brake shoe to the drum to cause a brake action.
    On the other hand, when the brake pedal is released, the hydraulic pressure of the master cylinder is lowered, so the brake shoe is returned to its original position by the force of the return spring, and the brake fluid in the wheel cylinder is returned to the master cylinder to release the brake action.
    At this time, when the brake is operated, severe friction and heat are generated due to the contact between the lining and the drum.
    In this case, the life of the parts is reduced due to the wear of the contact portion, and for these reasons, the braking force is not smoothly secured, so the braking distance is lengthened, and further, there is a concern that an unforeseen traffic accident may occur.
    If the heat is severely affected by the tires adjacent to the brakes will have problems such as damaging the tires.
    In addition, depending on the driver's intention during braking, the braking is not immediately applied, but the hydraulic pressure is generated and the braking is applied by the propagation of the hydraulic pressure.
    In other words, braking is only applied when the foot brake pedal is pressed. At this time, the braking action is not immediately performed because the hydraulic path is applied. Therefore, the braking effect is expected immediately as it causes some princess distance. In this case, the braking distance becomes long. In this case, the braking distance is increased during braking at high speed, and the braking distance is increased by the heat generated by the continuous friction of the brake mechanism. There is a problem such as the risk of collision accident due to the sliding phenomenon between the tire and the road surface.
    The present invention has been made to solve the conventional problems as described above, the object of the present invention by using a pneumatic air pressure of the air conditioner compressor to perform a braking action, especially in a high-speed driving state, thereby reducing the initial braking time Accordingly, the present invention provides an auxiliary rotating brake device for improving braking performance.
    Auxiliary rotating brake device according to the present invention for achieving the above object, a plurality of actuators installed on the drive shaft and a brake pad attached to the front end, air conditioner compressor, air conditioner to operate by applying air pressure to each of the plurality of actuators The brake pedal piston sensor that reads the brake force value according to the vehicle speed, the braking force according to the vehicle speed, and sends the signal to the ECU. When the value of the brake pedal piston sensor exceeds the reference value, a relay is connected to send air pressure of the air conditioner compressor to multiple actuators simultaneously. If you press the accelerator pedal to release the check valve 1 and brake, the relay will be disconnected to turn off the air compressor. At the same time, when the air conditioner is pressed, the relay is connected to operate the air compressor. Shiki Is characterized in that consisting of a check valve 2.
    According to the above features, the device according to the present invention first brakes the drive shaft first, and the wheel wheels are braked secondly by the existing brake device to shorten the initial braking time due to the rapid braking action, thereby improving the braking performance. Let's go.

    Reference numeral 12 is a piston, and reference number 13 is a return spring.
    The operation and effects of the present invention having such a configuration will be described.
    When the brake pedal piston sensor 16 senses the speed of stepping on the brake pedal 3 and sends the signal to the ECU 15, the ECU 15 reads the braking force value corresponding to the vehicle speed to determine that it is above the reference value. In this case, the relay 17 is connected to send the air pressure of the air conditioner compressor 14 to the respective actuators 10 through the check valve 1 19.
    Accordingly, the brake pads 11 attached to the pistons 11 of the respective actuators 10 move forward to closely contact the drive shafts 1 to perform pre-braking.
