摘要： An object of the present invention is to provide a brake device in which brake feeling can be improved. In response to depression of a brake pedal 6, an electric brake 5 mounted on the rear side starts to generate a braking force at the time of stroke h1 before a fluid pressure brake 4 mounted on the front side starts to generate a braking force when the stroke reaches stroke h2. In the conventional art, the braking force on the rear side is set according to the fluid pressure on the front side, and braking can be controlled only by the response of the fluid pressure. In the conventional art, an invalid stroke is long, and when the stroke enters a braking force zone where a braking force is generated according to a pedal stroke, the braking force suddenly increases relative to an advance of the stroke (rigid impression), whereby the driver often feels discomfort and pedal feeling is deteriorated. On the other hand, in the present invention, the rear side can generate a braking force prior to the front side, whereby it is possible to reduce rigid feeling, and therefore improve pedal feeling.

摘要： When a stroke speed exceeds a reference value of a stroke speed threshold value, a solenoid is energized to tract an armature, thereby opening an atmospheric valve independently of the position of a plunger. Consequently, power pistons, together with an output rod, are moved forward by a thrust corresponding to a pressure difference between a constant-pressure chamber and a variable-pressure chamber to perform a full-power braking operation. A reaction-adjusting mechanism contributes to an improvement in safety by functioning in such a way that when the part of the reaction force from the output shaft that is transmitted to an input rod reaches a predetermined value, a boosting ratio is increased, so that the reference value of the stroke speed threshold value can be set high to prevent unnecessary braking.

摘要： The present invention provides a booster in which magnitude of output can be adjusted also by an operation of a solenoid mechanism. An armature (13) is shifted to the right (in FIG. 1) in opposition to a returning spring by applying electricity to a solenoid (39), with the result that a space (80) on one end of the armature is communicated with a constant pressure chamber (5) through a passage (T3). When an electromagnetic force acting on the armature (13) exceeds a predetermined value, a distal end of a valve member (28) is shifted to the right (in FIG. 1) via a cylindrical member (31) to open an atmospheric valve (34), thereby introducing the atmosphere into a variable pressure chamber (6). The pressure in the variable pressure chamber is applied to the other end of the armature and the difference in the pressure tends to move the armature toward its home position.

摘要： In a cylinder body of a cylinder apparatus of the present invention for a brake fluid pressure control system, primary and secondary pistons having different pressure-receiving areas are provided. A pressure chamber between the primary and secondary pistons is communicated with a reservoir through flow passages formed between the cylinder body and a sleeve and between the sleeve and the secondary piston. In normal operation of the brake fluid pressure control system, the cylinder apparatus serves as a stroke simulator by releasing the fluid in the pressure chamber through the flow passages to the reservoir and contracting a spring in the pressure chamber. In the event of a failure of the system, the cylinder apparatus serves as a tandem master cylinder in which the flow passages are closed by a seal member in accordance with movement of the secondary piston, and the primary and secondary pistons move, while substantially no contraction of the spring in the pressure chamber occurs.

摘要： The present invention provides a brake booster that, although simple in construction, capable of adjusting the braking force derived by operation of a solenoid mechanism without worsening the braking response. In the brake booster according to the present invention, when a movable member (34) is shifted toward the rear side by electromagnetic force of a solenoid (31), the shifting movement is transmitted to a valve seat member (21) through pins (50) to open an atmospheric valve (27) through which air is introduced into a variable pressure chamber (9,10), whereby a pressure difference is created between the variable pressure chamber and a constant pressure chamber and generates booster output (thrust output force). In the present invention, pressure in the constant pressure chamber is introduced into a chamber (54) formed at one end of the movable member (34) through a passage (56), and atmosphere is introduced into a chamber (55) formed at the other end of the movable member (34) through a passage (57), thereby exerting on the movable member (34) a reaction force caused by the pressure difference between the variable pressure chamber and the constant pressure chamber. Thus, the booster output becomes proportional to the electric current supplied to the solenoid (31). Further in the present invention, the size of the passage (57) is determined properly so as to limit air introduced therethrough into the chamber (54) and keep the reaction force small until the booster output reaches an adequately level, thereby preventing the breaking response from deteriorating.

摘要： A load-responsive hydraulic control apparatus includes a valve operating member for opening a valve portion capable of permitting and preventing a master cylinder from communicating with the rear wheel cylinders of a rear wheel brake system. A plunger is provided for receiving hydraulic pressure from a branch path branched from the rear wheel brake system between the valve portion and the master cylinder and for opening the valve portion via the valve operating member when the received hydraulic pressure reaches predetermined hydraulic shifting pressure. An inertia valve blocks the branch path when predetermined deceleration is achieved.

摘要： The present invention relates to a brake fluid pressure control apparatus in which a casing contains a pump communication port separately from a master cylinder communication port. A spool is also provided which limits the communication between the pump communication port and the master cylinder communication port in a manner such that the discharge pressure from the pump is not added directly to the master cylinder. Additionally, in the intake and discharge sides of the pump, a bypass channel is provided. In this bypass channel, a relief valve is provided which allows the escape of pressure force to the intake side of the pump in the case when the pressure force between the discharge side of the pump and the flow control increases to a high pressure. Furthermore, because the brake fluid is normally designed to be discharged from the pump to the flow control valve at approximately a fixed flow rate by means of the relief valve, there is no return of brake fluid to the master cylinder via the flow control valve, and stroke fluctuations of the master cylinder can be eliminated. Additionally, the necessity for providing an orifice between a pump communication port and the master cylinder communication port disappears.
