Description

Apparatus for measuring brake-oil of vehicle

The present invention relates to a brake fluid measuring apparatus of a vehicle, and more particularly, to a brake fluid measuring apparatus of a vehicle so that the state of the brake fluid used in the vehicle can be accurately confirmed by a separate measuring mechanism.

In general, when checking the state of brake fluid used in a vehicle, uncertainty is determined by judging whether to replace the oil by visually seeing the color and turbidity of the oil state and subjecting it to a subjective judgment (experience). The exchange is made more than necessary, which causes a lot of waste and does not give consumers the reliability of the exchange cycle.

If you continue to use the brake fluid after the replacement cycle or if you use excessive brakes, the brake may not work properly due to the phenomenon of vapor lock, which causes the accident of the vehicle. It is a situation that is required to be.

After 1 year of replacing the brake fluid, 3 ~ 3.5% of water will be generated, and 4 ~ 5% of water will be generated after 2 years. Vapor-lock occurs in midsummer because of this increased moisture in the brake fluid. Excessive use of brakes on long downhill roads in vapor lock vaporizes oil in the wheel cylinders and brake pipes due to frictional heat in the wheels, and bubbles are formed as if air is introduced into the brake circuit. At this time, even if you step on the brake, the sponge goes off completely as if you step on the sponge, and the brake is not working.

The heating temperature is checked and operated for a predetermined time until the maximum temperature is reached.

At this time, if the brake fluid is not confirmed, the progression to the heating step is not made, since the heater 230 may malfunction when the heating unit is operated in the absence of the brake fluid.

When the maximum temperature is reached, the heater 230 is stopped and the measured maximum temperature is displayed on the display unit 140.

In addition, by outputting to the printer 131 on the upper portion of the enclosure (A) through the print output unit 130 can report the brake fluid state to the evidence or the consumer.

The above output is for knowing the oil condition and oil type, and each brake fluid displays the oil type on the lid of the brake fluid container of the vehicle, and the oil type is Dot3, Dot4, Dot5, Dot5.1. It is possible to select an exchange time since the state of oil can be accurately identified according to how much the temperature is indicated by the numerical table which displays and stores the highest temperature and the lowest temperature for each dot in the microcomputer 190 of the main board.

By experience, the operator can check the condition of the brake fluid according to the temperature, and also check the oil type (the oil type is indicated on the vehicle but can be checked by temperature if it is unknown).

In addition, the display unit 140 may display each operation state by letters or numbers, and an alarm buzzer 180 for outputting a warning sound may be installed to display each operation step as a sound.

After the measurement is completed, the user presses the pump switch 270 formed on the housing A, the brake fluid temporarily stored in the brake fluid input container 300 by the operation of the pump 260 is the brake fluid recovery The tube 301 is recovered and stored in the storage container 310.

According to the brake fluid measuring apparatus of the vehicle according to the present invention configured as described above, the state of the brake fluid of the vehicle can be measured to determine the normal operation of the oil and its replacement time accurately by measuring the maximum temperature, using a test rod It is convenient to take out the brake fluid, and it is convenient to use the printer and battery in the device, and it is possible to protect the environment by using the storage container to recover the brake fluid remaining after the test.

On the other hand, by adding a brake fluid changer to the brake fluid measuring device of the present invention, it is possible to accurately check whether the oil is operating normally and the time of replacement by measuring the brake fluid condition, and at the same time perform the operation of replacing the brake fluid of the vehicle. can do.
