摘要： In a vehicle brake system including a pneumatic force multiplier apparatus in which a power piston moves by virtue of a pressure difference between atmospheric and negative pressure, a manual brake switch is provided to apply braking force without need for depressing the brake pedal. A controller includes a deceleration calculating circuit reading vehicle speed for every specified number of seconds and calculating the amount of deceleration. The deceleration is compared with a predetermined value and braking force is increased, maintained, or decreased depending on whether the vehicle is running on a downwardly sloping, level, or unwardly sloping road.

摘要： A valve body 2 is connected to a power piston, which divides a housing into a constant pressure chamber (negative pressure) and a variable pressure chamber. In the valve body 2, there is provided a brake assisting mechanism 10 between a reaction disk 3 and a plunger 9. A poppet seal 12 is opened by movement of the plunger 9, to thereby introduce atmospheric air into the variable pressure chamber and generate a thrust force in the power piston. During rapid braking, a plunger rod 23 advances relative to a sleeve 21, and balls 30 shift outward and the plunger rod 23 directly abuts against a reaction rod 22, resulting in contraction of the brake assisting mechanism 10. Therefore, the amount of movement of the plunger 9 can be increased without being affected by a reaction force from the reaction disk 3, thus enabling rapid development of servo power.

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： A brake fluid pressure control system includes an external source of fluid pressure, a wheel cylinder, and a fluid pressure control valve disposed between the external source of fluid pressure and the wheel cylinder. A controller is operable to control the fluid pressure control valve whereby fluid pressure under control is fed from the external source of fluid pressure to the wheel cylinder. When a change in pressure within the wheel cylinder occurs, a fail safe valve is operable to disconnect the wheel cylinder from the fluid pressure control valve and instead, connect the wheel cylinder to a master cylinder. Inspection of the fail safe valve is carried out by disconnecting the wheel cylinder from the control valve when no brake is applied, feeding fluid pressure from the external source of fluid pressure to the wheel cylinder, and detecting a change in pressure within the wheel cylinder. An alert device is provided to give a warning in the event of a system failure.

摘要： The present invention relates to an improved antiskid control apparatus for vehicles. When the front wheel on either one of the right and left sides is antiskid-controlled, this apparatus detects whether the road surface is in the condition of split .mu. in which the road surface friction coefficient is different between the right and left wheels by more than the prescribed value. When the road surface is found to have a split .mu. condition, antiskid control should be implemented on the front wheel mentioned above. To control the rise in brake fluid pressure, the other front wheel must then be shifted in whatever direction facilitates control of the threshold value. In other words, even if a wheel does not attain a sufficient coefficient of surface friction, antiskid control is needed to control easily the rise in brake fluid pressure. A large side force is applied continuously to the vehicle, thereby reducing slippage and cancelling the yaw moment.

摘要： The present invention provides an electric disk brake which enables an operation for wiring the harness to be easily conducted without the risk of lowering production efficiency. A caliper body-side connector 26 which, together with a harness-side connector 24 of a harness 23, forms a connector 25, is provided in a caliper body 3. In the caliper body-side connector 26, first to fourth lead-out terminals 30a to 30d connected to an electric portion for an electric motor are arranged in this order from a first side portion 20a towards a third side portion 20c of a cover 20. In the harness-side connector 24, a first set of first to fourth harness-side terminals and a second set of first to fourth harness-side terminals independently connected to the first to fourth lead-out terminals 30a to 30d are arranged in reverse order. When an electric disk brake 1 is used for each of the left rear wheel and the right rear wheel, one of the first set of first to fourth harness-side terminals and the second set of first to fourth harness-side terminals is used for the left rear wheel while the other is used for the right rear wheel, and the first to fourth lead-out terminals and the first to fourth harness-side terminals are connected. The harnesses 23 extend in the same direction relative to the vehicle, thus ensuring ease of operation for wiring the harnesses 23.
