Abstract

PURPOSE:To prevent a creep phenomenon in an automatic car from occurring, by installing a brake locking device. CONSTITUTION:When a car stop is detected, a switch 15 comes into a state of being turned on to a normal contact, and a exciting coil 6 is energized with a continuous rating current whereby a moving iron core 7 is attracted toward a fixed iron core 4. After contact with the fixed iron core, a plunger 17 is kept at that position by dint of attraction due to a magnetic field of a permanent magnet 5. Thus, tip end 18 of the plunger 17 is closely fitted in an inner hole of packing 13. When a driver foot comes off a brake pedal, the packing 13 is pushed to the side of an inflow passage 8 by hydraulic pressure at the side of an outflow passage 9 and its escape passage 19 is also intercepted whereby braking pressure added in time of a car stop is left locked intact. With an accelerator pedal operated when one wants to start, the switch 15 comes ON to a revers contact and thereby diamagnetism is produced in the exciting coil 6 so that the attraction to the moving iron core by the permanent magnet 5 is thus released.

Description

【発明の詳細な説明】 主粟上皇■且分■ 本発明はオートマチック車のプレーキロ・ツク装置に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a play kilometer drive device for an automatic vehicle.

ｌ米且■ 乗用車にはクラッチ操作をなくし、アクセルとブレーキ
のみで運転できる所謂オートマチ・ツク車が多く利用れ
れるようになったことは周知の通りである。It is well known that so-called automatic cars, which do not require clutch operation and can be driven using only the accelerator and brakes, have become popular among passenger cars.

起こす危険性がある。Solution" ≧ "1" 1 point In an automatic car, when the switching lever is in the drive D state, there is a phenomenon called "creep" in which the car starts moving at a low speed even when the engine is idling. To prevent the car from moving while stopped, it is necessary to keep pressing the brake pedal, pull the parking brake, or switch the switch lever to neutral N or park P. Without such complicated operations, it is impossible to prevent the vehicle from starting to move due to creep while the vehicle is stopped. If you are careless and forget to do this, there is a risk that the car will start moving unexpectedly and cause an accident.

動きうる状態にあることと、切換レバーがＤのときには
ブレーキが作動していないことより生ずる。The above-mentioned drawback of conventional automatic 1-matic vehicles is that the engine and transmission are always connected through a fluid coupling.
This occurs because the brake is in a state where it can move at any time depending on the rotational speed of the engine and the magnitude of the load, and because the brake is not operating when the switching lever is in the D position.

る。この場合パツキンは逆止弁の機能を果たす。This device detects the stoppage of the wheel and instantaneously energizes the solenoid to hold the movable core in the switching position.The valve body is moved in accordance with the movement of the movable core, and the valve body is inserted into the seal and connected to the inflow path. In other words, the oil passage between the master cylinder and the brake cylinder of the brake device is shut off. This allows the hydraulic pressure in the brake cylinder to remain locked even if the driver takes his or her foot off the brake pedal. The gasket is arranged in the annular groove of the valve body and is formed to be slightly movable.As long as the pressure on the valve outflow path side is high, the gasket blocks the flow of fluid, but when the pressure on the valve inflow path side increases, the gasket blocks the fluid flow on the inflow path side. It is moved slightly by the pressure, allowing pressure oil to flow toward the outflow path through the escape path of the seal. Therefore, the voluntary brake pressure can be increased. In this case, the seal acts as a check valve.

いう利点を有する。Thanks to the present invention, the brake pressure is maintained even when the foot is released from the brake pedal, so the vehicle can be reliably stopped even when the switching lever is in the D position.
Not only can this phenomenon be prevented, but also in a stopped state,
This has the advantage that when the brake pressure is insufficient, it is possible to increase the brake pressure at will by stepping on the brake pedal.

Therefore, it is possible to prevent the wear and tear of the bathody. In addition, since a monostable solenoid valve is used, there is no disconnection in the electrical system, TDCB connection, etc.
A stable state can be achieved without the valve switching unexpectedly due to an accident such as a defective switch.

状は図の例に限定されない。The gasket 13 has at least one escape passage 19 extending over the entire outer peripheral surface from one side surface, the left side in the figure, on the outlet side, and the escape passage 19 is constantly in communication with the valve chamber 10. Escape route 19 is on the side of Patsukin and is almost half-i.
It is formed as a groove extending in the direction, and on the outer peripheral surface as a swamp extending in the axial direction. The other side surface of the packing, that is, the side surface on the right side of the inflow path in the figure, is formed so as to completely block the valve chamber 10 and the escape path 19 when it comes into contact with the side surface of the annular groove. Even if the internal hole of the gasket 13 is sealed by the valve body 17, the gasket 13 blocks the fluid when it comes into contact with the right side of the annular WJ12, and allows the fluid to flow when it comes into contact with the left side, so the gasket 13 acts as a check valve. It has the following functions. The shape of the gasket is not limited to the example shown in the figure as long as it has the function of this check valve.

遮断される。Since the plunger 17 of the valve 3 is fixed to the movable core 7 or is brought into contact with the movable core 7 by the action of the spring 14, the movable core 7 is held in the operating position shown in FIGS. 2 and 3. During this period, the tip 18 of the plunger 17 is in close contact with the internal hole of the gasket 13, thereby blocking the inflow path 8 side and the outflow path 9 side of the valve chamber 10. As a result, the brake pressure oil when the vehicle is stopped is prevented from returning from the outflow passage 9 to the inflow passage 8, and the brake pressure applied when the vehicle is stopped is generally locked and maintained as it is. When the foot is released from the brake pedal, the hydraulic pressure acting on the inflow passage 8 decreases, and the seal 13 is pushed toward the inflow passage 8 by the hydraulic pressure on the outflow passage 9 side, as shown in FIG. 3, and escapes. Route 19 is also blocked.

シリンダの圧力油をロックする。When the brake pressure applied during stopping is small and the braking force is insufficient on a slope, etc., when the brake pedal is depressed, brake oil is supplied from the master cylinder through the inlet passage 8. At this time, the gasket 13 is pushed toward the outflow path 9, and a gap is created between the side surface of the annular groove 12 and the inflow side surface of the gasket 13, and the gasket 19 is opened, allowing the fluid to flow freely. The brake fluid is supplied to the brake cylinder through the valve chamber 10 and the outflow passage 9. The braking force can therefore be increased at will. When the brake pedal is released, the pressure in the inlet passage 8 decreases, and the gasket 13 returns to the state shown in FIG. 3, locking the pressure oil in the brake cylinder in the increased pressure state.

バッテリーの消耗の恐れがない。When you press the accelerator pedal when you want to start, or when you pull the parking brake to park, the switch 15 turns on to the reverse contact, and the reverse magnetic field is stopped in the excitation coil 6 compared to when it is activated as shown in Figure 2. , the attractive force of the permanent magnet 5 on the movable iron core is released. As a result, the movable core 7 is returned to the state shown in FIG. 1 by the action of the spring 10 via the plunger 17. By connecting a brake locking device formed as a monostable solenoid valve to the flow path between the master cylinder and the brake cylinder, it is possible to prevent the creep phenomenon of automatic vehicles, and furthermore, since it is a monostable solenoid valve, The solenoid only needs to be energized for a very short time.
There is no fear of battery consumption.
