摘要： In a brake booster of the present invention, by depression of a brake pedal 3, an input shaft 4 travels to the left, a pedal input converter generates thrust, and a valve element 5a moves to the left. A valve passage 5a1 is shut off from a valve passage 5b1 and a valve passage 5a2 is connected to a valve passage 5b2 so as to develop output pressure Pr at an output port 5c of a control valve 5 because of the pressure of a pressure source. The output pressure Pr is supplied to a wheel cylinder 7, thereby actuating the brake. At this point, since the displacement of the input shaft 4 required for operating the control valve 5 is defined only by the converter 6, the input side is not affected by the brake rigidity of a circuit from the control valve 5 to the wheel cylinder 7. The output pressure Pr of the control valve 5 acts on the valve element 5a through a first reaction receiving portion 8 and is regulated to pressure proportional to the thrust of the converter 6. The second reaction force is transmitted to a driver through a second reaction receiving portion 9. The control of the output can be conducted during the operation regardless of the input of the input side and the respective characteristics can be varied without being affected by the output side.
摘要翻译：在本发明的制动助力器中，通过按压制动踏板3，输入轴4向左行驶，踏板输入转换器产生推力，阀元件5a向左移动。阀通道5a1从阀通道5b1截止，阀通道5a2连接到阀通道5b2，以便由于压力源的压力而在控制阀5的输出端口5c处产生输出压力Pr。输出压力Pr被提供给轮缸7，从而致动制动器。此时，由于仅通过转换器6来限定操作控制阀5所需的输入轴4的位移，所以输入侧不受从控制阀5到轮缸7的回路的制动刚度的影响控制阀5的输出压力Pr通过第一反应接收部8作用在阀体5a上，并被调节成与转换器6的推力成正比的压力。第二反作用力通过第二反应传递给驾驶员输出的控制可以在操作期间进行，而与输入侧的输入无关，并且可以改变各个特性而不受输出侧的影响。

摘要： A brake system 1 of the present invention comprises a brake operating means 2 such as a brake pedal for carrying braking operation, a fluid variable stroke means 3 which variably controls the stroke of the brake operating means 2 by using fluid, and a braking force output means 4 which is actuated by the operation of the brake operating means 2 to produce braking forces. By manipulating the brake operating means 2, the braking force output means 4 performs the braking operation. The traveling rang of the brake operating means 2 i.e. the stroke can be changed variously by the fluid variable stroke means 3 using fluid. Since the stroke of the brake pedal can be changed as mentioned above, a proper pedal stroke can be obtained.

摘要： In a brake boosting system the present invention, as it is decided that brake assist is necessary, a pump 53 is driven, and a solenoid valve 72 is switched to its communication position, and a solenoid shut-off valve 75 is opened. Then, the pump 53 sucks brake fluid from a reservoir 9 through the solenoid valve 72 and sends out the brake fluid to the pressure intensifying chamber 21 through the solenoid shut-off valve 75. At this point, an output shaft 11 has already advanced and a radial hole 38 is positioned ahead of a seventh cup sealing member 31 so that the pressure intensifying chamber 21 and the reaction chamber 33 are shut off from the reservoir 9 so as to be in the sealed state. Therefore, pump discharge pressure is supplied to the pressure intensifying chamber 21 and the reaction chamber 33 so that the pressure in these chambers is intensified. Since the intensified pressure acts on the primary piston 12, the master cylinder pressure is intensified to a value greater than that of normal braking. As mentioned above, by intensifying the master cylinder pressure when necessary, large braking force can be obtained with a simple structure.

摘要： A tubular member 18 is slidably fitted into a valve body, and is formed with a vacuum valve seat 21. The tubular member 18, a valve plunger 16 and the valve body 3 are maintained in their inoperative positions shown by abutment against a key member 13. A holder 14 is formed with a tapered surface 14a to assist in allowing an elastic deformation of a reaction disc 15. Immediately after the commencement of operation of a valve mechanism 7 as an input shaft 8 is driven forward, the input shaft 8 and the tubular member 18 are maintained in their inoperative positions until a rear end face of a variable pressure passage 28 abuts against the key member 13. The operating stroke of an input shaft 6 can be chosen to be less than the operating stroke of an output shaft 11 while preventing the jumping value from increasing to an excessively high value.

摘要： In a negative pressure booster of the present invention, a threshold line for starting a BA operation at a pedal step-in speed equal to or more than a predetermined speed is set, an inclination of the threshold line is set to a value equal to a servo ratio SR2 smaller than a servo ratio SR1 during a usual braking operation in a low input region (a small pedal step-in region) and is set to a value equal to the servo ratio SR1 during the usual braking operation in a high input region (a large pedal step-in region). That is, the threshold line for starting the BA operation is adjustable between the high input time and the low input time. Further, even when a brake pedal is stepped in at the step-in speed equal to or more than the predetermined speed in spite of a fact that the time when the braking is performed is not an emergency time, the BA operation is not performed and hence, an undesired BA operation can be prevented. In emergency and, at the same time, when the brake pedal is stepped in at the step-in speed equal to or more than the predetermined speed and with a step-in force equal to or more than a predetermined step-in force, the BA operation is started.
摘要翻译：在本发明的负压增压器中，设定用于以等于或大于预定速度的踏板踏入速度开始BA操作的阈值线，将阈值线的倾斜度设定为等于或等于在低输入区域（小踏板踏入区域）中的通常制动操作期间的伺服比SR 2小于伺服比SR 1，并且在通常的制动操作期间被设置为等于伺服比SR 1的值高输入区域（大踏板踏入区域）。也就是说，用于启动BA操作的阈值线在高输入时间和低输入时间之间是可调节的。此外，即使制动踏板以等于或大于预定速度的踏入速度进入步进，尽管执行制动的时间不是紧急时间，但是不执行BA操作，因此，可以防止不期望的BA操作。在紧急情况下，同时，当制动踏板以等于或大于预定速度的踏入速度并以等于或大于预定踏入力的踏入力进入步进时， BA操作开始。

摘要： In an automatic brake booster, a sleeve 18 constituting a valve mechanism 15 has a drive portion 50 disposed on the front side, a valve portion 51 forming a second valve seat 19, a mating portion 52 for mating with a valve seat portion when the drive portion is moved forward, and a conical spring 53 disposed between the drive portion and the valve seat portion and used for separating both members from each other. The conical spring is compressed during the normal braking operation so as to make the opening amount of the second valve seat greater than that during the automatic braking operation. Moreover, a plate plunger 40 for transmitting braking counterforce is relatively displaceably provided and a first member 71 and a second member 71 for mutually contacting a reaction disc 41 is also provided, so that the braking counterforce of the first member is transmitted to the sleeve during the automatic braking operation.

摘要： A brake system contains a safety mechanism which terminates an automatic brake upon detecting that unnecessary braking force is developed as a result of a failure in an automatic brake controller. In the event a braking output is developed when neither a brake pedal nor the automatic brake controller is operated, the safety mechanism determines the occurrence of an abnormality, and interrupts a communication between the master cylinder and the wheel cylinder while decompressing the oil pressure in the wheel cylinder by discharging it into a low pressure accumulator. The safety mechanism allows the automatic braking to be terminated, thus allowing a risk of a collision by a succeeding vehicle to be avoided and allowing a vehicle to continue running.
