    摘要： A brake booster 1 of tandem type includes a solenoid 16 within a valve body 6. The solenoid 16 is provided with a forwardly disposed holder 42 and a rearwardly disposed yoke 43, with a spool 44 held sandwiched therebetween and with a piston 56 disposed to be moveable around the inner periphery. A tubular guide 56A is formed on the front portion of the piston 56 while an annular guide 56B is formed on the rear portion of the piston 56. The tubular guide 56A is slidably fitted into the inner periphery of the holder 42 while the annular guide 56B is slidably fitted into the inner periphery of the yoke 43. When the solenoid 16 is energized to cause the piston 56 to move back and forth relative to the holder 42 and the yoke 43, this movement is guided by the both guides 56A, 56B. This arrangement permits a smooth back-and-forth movement of the piston 56 as compared with the prior art.

    摘要： The invention relates to a brake system including a brake booster. A pneumatic pressure operated brake booster VBB or a liquid pressure operated brake booster includes a valve mechanism which is urged by a force of depression applied to a brake pedal BP to switch a flow path to cause the brake booster to develop an output which depends on the magnitude of the force of depression. A solenoid SOL urges the valve mechanism in the same direction as or in the opposite direction from the force of depression. A controller ECU is responsive to a braking effort increase/decrease demand signal to increase or decrease the urging force which is applied by the solenoid to the valve mechanism, thus increasing or decreasing the output from the brake booster. An output from the brake booster can be freely controlled independently from the force of depression applied to the brake pedal in response to a braking effort increase/decrease demand. The arrangement is applicable to a wide variety of brake systems onboard a vehicle such as a regenerative brake unit, an engine brake or an exhaust gas brake unit or a brake assisting apparatus.

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.

    摘要： A brake system including a negative pressure booster, a master cylinder of tandem type and an intensifying arrangement. The intensifying arrangement defines an intensifying chamber disposed rearward of a primary piston, a pump for supplying a braking liquid to the intensifying chamber, and a reaction piston and a sleeve for controlling the pressure of the braking liquid which is supplied to the intensifying chamber. As a brake pedal is depressed and the intensifying arrangement is actuated, a sum of an urging force from the negative pressure booster and an urging force from the intensifying arrangement operates the primary piston to develop a master cylinder pressure. The sum is proportional to the input or a force depressing the brake pedal. In this manner, a simple arrangement assures a satisfactory booster function even after the negative pressure booster has reached a full load point or the limit of its assistance or in the event of the failure of a source of a negative pressure for the negative pressure booster.

    摘要： A tandem brake booster includes a solenoid within a valve body, and the solenoid may be energized to move a first tubular member disposed on the valve body rearward. When an input shaft is driven forward in the inoperative condition of the brake booster, a vacuum valve is closed while an atmosphere valve is opened in the similar manner as occurs in the prior art, thus actuating the tandem brake booster 1. When an input or the force of depression applied to a brake pedal rises to a given value X during the operative condition of the brake booster, the solenoid is energized, whereupon the first tubular member is moved rearward relative to the valve body, and the valve element is also moved rearward. This opens the atmosphere valve which has been closed during the servo balance condition, allowing a further introduction of the atmosphere into variable pressure chambers B, D, enabling a rise in the output even though the input remains unchanged. In this manner, the invention provides a functioning which is equivalent to a brake booster which is arranged to provide a variable servo ratio.

    摘要： A master cylinder which includes a primary piston and a thrust piston disposed within a housing, and defines an intensifying chamber at a location rearward of the thrust piston. An input shaft has a front end which is disposed within the intensifying chamber. The thrust piston is formed with a communication path (discharge passage), and a control valve is disposed between the thrust piston and the front end of the input shaft to open or close the communication path (discharge passage). When the input shaft is driven forward under the inoperative condition shown and the pump is operated to introduce a discharge pressure from the pump into the intensifying chamber, a liquid pressure is generated in the intensifying chamber and drives the primary piston forward, generating a liquid pressure in a liquid pressure chamber. In this manner, a master cylinder can be provided which has a simple and inexpensive construction with a reduced number of parts and which is compact in size. The master cylinder is capable of providing an increased braking force as required by intensifying a master cylinder pressure.
