CONSTITUTION:A solenoid valve for pressure increasing 31, a restrictor 32, a pressure sensor 33, and a solenoid valve for antiskid 34 are provided in a brake line 30 for connecting a brake 11 which gives control force to a wheel 10 to a hydraulic pressure source 20 in order from the hydraulic pressure source 20 to the brake 11. Also a relief line 40 is branched from the brake line 30 at a position between the restrictor 32 and the pressure sensor 33, and a pressure reducing solenoid valve 42 is provided in the course of the relief line 40. Then output signals from the pressure sensor 33 and a rotating speed sensor 12 are inputted into a controller 50. Thus a braking pressure at which an actual deceleration rate calculated according to the output signals from the rotating speed sensor 33 meets a target deceleration rate selected by deceleration rate selecting signals is calculated by the controller 50, and the solenoid valves 31 and 42 are controlled according to a deviation from the actual pressure.

1 Problems to be solved by the invention: The electrohydraulic servo valve used in conventional autobrake control devices has a response frequency as high as 1.001-1 z or more, and the adjustment is approximately proportional to the input current. It has many advantages, such as being able to obtain pressure, but it also has many disadvantages. For example, the unit price of the product is high. Weak against hydraulic fluid contamination. There is no knee magnetic resistance as the torque motor section is operated by weak magnetic force. It requires a constant supply of hydraulic oil, consumes a large amount of oil, and requires a hydraulic pump. There is a large hysterinos between the input current and the regulated pressure.

Conventional autobrake control devices inherit various drawbacks of electrohydraulic servo valves, and are therefore expensive and have low durability. Furthermore, when used as an emergency brake, it is unreasonable to constantly circulate hydraulic oil using a hydraulic pump. Therefore, its use was limited to some expensive systems such as braking systems for large passenger aircraft.

Simultaneously with the start of autobrake operation, the pressure increase solenoid valve 31 is switched from the off state to the on state. Thereby, pressure oil from the hydraulic power source 20 is sent to the brake 11 through the brake line 30. However, at the beginning of operation, the brake pressure does not increase by 2.

This is because a certain amount of hydraulic oil needs to flow into the brake cylinder in order to bring the brake disc, which is in a non-contact state, into a contact state and generate braking torque. When the brake discs come into contact, the brake pressure increases suddenly. Then, when the brake pressure exceeds the target brake pressure, the pressure increase solenoid valve 31 returns to the OFF state. When the target brake pressure increases and exceeds the brake pressure again, the pressure increase solenoid valve 31 is opened. While repeating this, brake pressure control is continued until the target brake pressure reaches the maximum value.

When the target brake pressure starts to decrease and becomes excessive with respect to the target brake pressure, the pressure reducing solenoid valve 42 is switched from the OFF state to the ON state. This causes the brake pressure to drop significantly. Then, when the brake pressure matches the target brake pressure, the pressure reducing solenoid valve 42 returns to the OFF state. By repeating this, the brake pressure follows the decrease in the target brake pressure.

When skid is detected during braking, the anti-skid solenoid valve 34 is activated. This releases brake pressure little by little to prevent skidding. In addition, during this time, the pressure increasing solenoid valve 31 and the pressure reducing solenoid valve 4 are closed.
2 is activated, a surge is generated in the pressure of the pressure sensor section, so the controller 50 functions to stop these operations.

According to the autobrake control device shown in FIG. 1, by optimizing the line resistance of the strifter 41 and the like provided in the relief line 40, autobrake control with accuracy equivalent to that of an electro-hydraulic servo valve becomes possible. In addition, because it uses a solenoid valve, it is inexpensive, resistant to contamination and magnetic fields, consumes little oil, and has high hydraulic pressure! 20 does not require a pump and can use an accumulator, making it a reasonable structure for emergency use.

3. Effects of the Invention As is clear from the above explanation, the autobrake control device of the present invention has braking performance equivalent to that of the conventional device using a servo valve, and has the following advantages compared to the conventional device. It has many advantages. It is possible to construct an autobrake system that is inexpensive, has high magnetic resistance and resistance to hydraulic oil contamination, and consumes less oil. Since the brake pressure is fed, brake control without hysteresis is possible. Since it consumes less oil, a small accumulator can be used as a hydraulic power source, resulting in a rational configuration for an emergency brake system. Because it has magnetic resistance,
It can also be used in strong magnetic field environments such as those in linear motor cars.
