Description

A brake system for traffic holdups

The present invention relates to a braking device for an automatic transmission vehicle, and more particularly, to a traffic jam brake device used when the vehicle is congested due to a traffic jam.

A brake system is an important device used to keep a car parked at the same time as decelerating or stopping a driving car. In general, a brake system converts the kinetic energy of the car into thermal energy using a friction force and releases it into the atmosphere. Friction brakes with braking action are used.

In addition, various types are used for the braking device, and there are a main brake for braking when driving and a parking brake for parking. The main brake is called a foot brake because it is operated by the driver's foot, and the parking brake is also called a hand brake because it is mainly operated by hand.

Depending on how the brake is operated, there are mechanical methods using hydraulic loads and wires and hydraulic types using hydraulic pressure. In general, the foot brake is hydraulic and the parking brake is mechanical.

According to the type of hydraulic brake, drum type brake and disc type brake are mainly used, and drum type brake consists of wheel cylinder, brake shoe, back plate and brake drum. The brake is pressed by the cylinder.

On the other hand, the drum-type brake is composed of a wheel cylinder, a brake shoe, a back plate and a brake drum, and the brake brake wheel cylinder is installed to both sides toward the circumferential inner surface of the brake drum to brake the brake is made.

1 shows a configuration of a general hydraulic brake system. For convenience of illustration, only the wheels on one side of the front and rear wheels are illustrated.

As shown, when the brake pedal 1 is operated, the piston 2a in the master cylinder 2 is advanced by the push rod 1b connected to the pedal arm 1a, thereby compressing the brake oil in the cylinder 2. The brake oil is compressed through the brake lines 3 and 4 on the front and rear wheels, and the wheel cylinder 6 of the caliper (front wheel side) or brake shoe (rear wheel side) communicating with the ends of the brake lines 3 and 4. 8) by supplying high pressure brake oil, the lining or the pad is pressed against the brake drum 10 (internal extension type) or the disc (caliper type, front wheel side) to brake by friction. In addition, when the brake pedal is released, the brake oil that has been compressed returns to the master cylinder 2 and the brake is released.

However, the conventional hydraulic brake system configured as described above has to repeatedly operate the brake pedal when the traffic jam is formed due to the traffic jam.

Therefore, the driver feels fatigue of the ankle by repeated operation of the brake pedal, which causes a problem in safe driving of the vehicle.

In order to solve this problem, an object of the present invention is to maintain the distance between vehicles by operating the switch by hand instead of operating the brake pedal by foot when the traffic jam is formed due to the traffic jam. It is to provide a brake device for traffic jams.

1 is a configuration diagram showing a conventional general hydraulic brake system.

Figure 2 is a block diagram showing a traffic jam brake device of the present invention.

In order to achieve the above object, the present invention provides a power supply, an overdrive switch and a braking mode switch connected in parallel to the power supply, a relay switch connected to the overdrive switch and a braking mode switch, and an over connection connected to the relay switch in parallel. Provided is a brake device for a traffic jam, comprising a driver control circuit and a braking operation part.

Hereinafter, with reference to the accompanying drawings, the configuration of the brake device for a traffic jam of the present invention in detail as follows.

Figure 2 is a block diagram showing a traffic jam brake device of the present invention. As shown, the traffic jam brake device of the present invention power source 10, the over-driver switch 11 and the braking mode switch 12 connected in parallel to the power source 10, the over-driver switch 11 and The relay switch 13 is connected to the brake mode switch 12, and the over driver control circuit 14 and the brake operating unit 15 are connected to the relay switch 13.

The overdriver switch 11 is installed at the shift lever of the automatic transmission, and the overdriver switch 11 is connected to the relay switch 13. In addition, the braking mode switch 12 is installed where the driver's hand easily reach, the braking mode switch 12 is also connected to the relay switch (13).

The relay switch 13 is in a normal state, i.e., connected to the overdrive control circuit 14 which will be described later, and when the braking mode switch 12 is switched on to the actuator 16 which will be described later. The switch is on.

The actuator 16 is configured to operate by an overdrive switch when the relay switch 13 is turned on by the operation of the braking mode switch 12, and the actuator 16 is braked. It is formed to operate the piston of the master cylinder 2 which comprises an apparatus.

Next, the operation of the traffic jam brake device of the present invention configured as described above is as follows.

As shown in FIG. 2, when the traffic jam is formed due to a traffic jam, the driver repeatedly operates the braking mode switch 12 by hand to turn on the relay switch 13. Is switched on. At this time, when the over driver switch 11 is turned on, the power supply 10 is applied to the actuator 16. When the power source 10 is applied to the actuator 16, the actuator 16 operates while operating the piston inside the master cylinder 2 to obtain a braking force to stop the vehicle.

When the vehicle that has stopped has to start again, when the switch is turned off by operating the overdrive switch 11 by hand, the power supply 10 is not applied to the actuator 16 and the actuator 16 is returned to its original position. Release the brake unit while returning to the state. In addition, when the braking mode switch 12 is turned off, the relay switch 13 is turned off and the overdriver control circuit 14 is operated by the operation of the overdriver switch 11.

Accordingly, the present invention is the power supply 10, the overdrive switch 11 and the braking mode switch 12 connected in parallel to the power supply 10, the overdrive switch (11) and the braking mode switch 12 Is connected to the relay switch 13, the overdrive control circuit 14 and the actuator 16 connected in parallel to the relay switch 13, and the braking operation unit 15 to which the actuator 16 operates. By constitution, when a traffic jam is formed due to a traffic jam, the traffic jam can be provided by maintaining a distance between vehicles by operating a switch by hand instead of operating a brake pedal by foot. Will be.

Therefore, it is possible to provide a traffic jam brake device that reduces fatigue accumulated on the driver's ankle and contributes to driving.
