Abstract

PURPOSE:To supply higher pressure and improve the safety by providing a valve to shut the connection passage between an entrance to the pressure generating source and an exit to a brake device and a one-way valve to allow the liquid movement only from the entrance to the exit. CONSTITUTION:Pressure liquid from a master cylinder 1 is supplied to a wheel cylinder via an entrance 16, a passage 17-21 and an exit 20. A car is sufficiently decelerated and electric current is sent from a control device to a bobbin 10 of a valve unit 1 according to a disconnection of a clutch and the like to close a valve 23. Thereby, the pressured liquid at the wheel cylinder side is enclosed to retain the brake force according to the liquid pressure. In order to increase the enclosed liquid pressure, a higher liquid pressure than this is generated at the master cylinder to open a one-way valve composed of a sealing member 29 and supplied to the wheel cylinder via this one-way valve, passages 26, 27 and 21, and the exit 20 for enclosing the higher pressure.

Conventionally, these devices include an inlet connected to a braking pressure generation source, an outlet connected to a brake actuating device, a passage connecting the outlet and the inlet, and a passage provided in the passage connecting the inlet and the outlet. A valve device capable of cutting off communication, a movable plunger arranged to enable the valve device to operate, and a bobbin arranged around the outer periphery of the plunger and energized in response to a command from an external control device. It is known that it has
The valve device is opened and closed in response to commands from the control device to maintain and release brake pressure.

In particular, C in the control device receives signals from various sensors (electrical and mechanical ones are installed as necessary) installed on the vehicle, etc., and detects when the vehicle, etc. has stopped on the boarding road. When the brake pressure that is being generated at that time is maintained as it is, and the vehicle remains stopped even if the driver releases the brake operation, and then when the driver attempts to start on the boarding road, the brake pressure from various sensors is maintained. With human power, the brake pressure is released in response to the clutch engagement operation, allowing the vehicle to easily start on the boarding road without the need to operate the handbrake.

However, in these conventional systems, the valve device is simply opened and closed, and once the valve is closed, the pressure on the braking action device side is only constant, and the slope becomes large on the uphill road. If the solenoid valve device is installed only on one side of the two-brake system, it may not be possible to contain enough pressure to keep the vehicle in a stopped state. Accidents occur in which a vehicle or the like backs up against the wishes of the driver who is in the vehicle and collides with a vehicle or the like behind the vehicle. In other words, even if the driver applies the brakes strongly to prevent the vehicle from moving backwards, the pressure on the actuating device remains constant, so accidents like this occur.

The only command given to such a device 1 is whether or not to energize the bobbin 10 from the control device, and when the bobbin 10 is energized, the plunger 14 acts against the valve spring 15 to cause the valve to open. The valve body 13 is seated on the seat 24 and the valve device 2

When the valve device 1 is demagnetized, the valve device 23 remains open, so that liquid can freely move from the mask cylinder to the wheel cylinder or vice versa.

Suppose that a vehicle or the like is running in this state without applying the brakes. Assume that a vehicle or the like is traveling on a boarding road and applies the brakes in order to stop for a traffic light or a railroad crossing.

When the brake is applied by the pressure fluid supplied to the wheel cylinder and the vehicle is sufficiently decelerated, the device 23 consisting of a control device closes, for example in response to the disengagement of the clutch.

これにより、ホイールシリンダ側へ供給されている圧液
は封し込められ、その圧液に応した制動力が保持される
As a result, the pressure fluid being supplied to the wheel cylinder side is sealed, and a braking force corresponding to the pressure fluid is maintained.

その後、車両等か完全に停止し、運転手がブレーキを解
除したとしても、上記制動力は停止状態を保持される。
Thereafter, even if the vehicle or the like comes to a complete stop and the driver releases the brake, the braking force is maintained at the stopped state.

At this time, if the sealed fluid pressure is low, the vehicle will try to move backwards, but the driver will apply the brakes again.
When a hydraulic pressure higher than the sealed hydraulic pressure is generated, the sealing member 29 is deformed by the pressure difference and the one-way valve opens, so that higher pressure can be sealed on the wheel cylinder side.

In this state, the driver performs the necessary operations to start (shifting gears, pressing the accelerator, releasing the clutch pedal)
When the valve device 1 is demagnetized in response to, for example, the clutch becoming in a so-called half-clutch state, the plunger 14 is effectively moved to open the valve device 23. Then,
The pressure fluid that has been confined in the wheel cylinder side moves toward the mask cylinder side not suddenly but gradually, mainly due to the throttling effect of the throttling passage 17, so that the braking force that was being held gradually decreases. As a result, the braking force gradually decreases and the driving force is gradually transmitted to the wheels in the half-clutch state, so that the vehicle can reliably start on the road without operating the handbrake.

After the vehicle or the like starts running, it starts running normally and the device 1 remains demagnetized.

■In addition to the valve device 23, it has a one-way valve that allows liquid to move to the wheel cylinder side, so even after the valve device 23 is closed, pressure fluid can be supplied to the wheel cylinder side, and the necessary braking force can be maintained. It can be confirmed and safety can be improved. In addition, the valve device 23
Since pressurized liquid can be supplied even after the valve is closed, a sufficiently high pressure can be contained even if the timing of excitation of the valve device 1 is advanced, and the operating characteristics tend to be safe.

■Because it has the throttle passage 17, the braking force that was maintained does not decrease suddenly but gradually, so even if the slope of the climbing road is large, the braking force will decrease before the braking force decreases completely. This provides enough time to transmit sufficient driving force to the wheels, allowing smooth and safe start-up.
