The actuating device for a vehicle brake system comprises a force input member, which can be coupled to a brake pedal, and a brake master cylinder. The brake master cylinder has at least one force transmission member. The force transmission member is coupled to the force input member in an articulating fashion. The force transmission member is positioned to transmit a force, which has been exerted onto the force input member, to the brake master cylinder. The actuating device has at least one elastically deformable positioning element. The at least one positioning element produces a holding force with which the at least one positioning element holds the at least one force input member in an installation position relative to the brake master cylinder.

An emergency stop apparatus includes a detecting device for detecting an obstacle intruding into a predetermined area around a working machine, an actuator fixed to a vehicle body of the construction machine or a member attached to the vehicle body, a coupling member for coupling an output shaft of the actuator with a brake pedal, and an electronic control unit. When the obstacle is detected by the detecting device, the electronic control unit actuates the actuator to move the brake pedal in an actuation direction of the service brake.

A remote braking assembly for facilitating a passenger to apply brakes in a vehicle includes a roller unit that is coupled to a floorboard of a vehicle. The roller unit is aligned with a brake pedal of the vehicle. A handle is movably positioned within the vehicle. The handle is directed toward a passenger seat of the vehicle such that the handle is accessible to a passenger in the vehicle. A cable is coupled between the handle and the brake pedal of the vehicle. The cable draws the brake pedal into a depressed position when the handle is urged into a braking position. In this way the passenger can remotely apply the brakes of the vehicle.

An operation apparatus includes a supporting element, an operation element including an arm whose basal end is rotatably supported by the supporting element and whose tip is provided with an acting element, and a return spring provided between the supporting element and the operation element, in which the return spring is housed in a compact manner without inviting an increase in the number of components. A return spring is provided between a first spring holder and a second spring holder. A supporting element is provided with a first side wall opposing the return spring in the lateral direction. An arm is provided with a second side wall opposing the first side wall and surrounding the return spring in conjunction with the first spring holder, the second spring holder, and the first side wall.

An electric booster for a vehicle including: a disc holder accommodating a reaction disc, a screw nut rotated in conjunction with an operation of a motor, a screw bolt linearly moved in conjunction with a rotation of the screw nut, a boosting block disposed between the reaction disc and the screw bolt, and contacting a radially outer portion of the reaction disc when the screw bolt moves, a pedal rod contacting a radially central portion of the reaction disc through the screw bolt and the boosting block, a disc holder pressing hole connected to the screw bolt, and disposed to face the disc holder, and a first breakage prevention gap part formed between the disc holder and the disc holder pressing hole.

A master cylinder includes: a cylinder body; an isolation wall provided inside the cylinder body, arranged between a first chamber and a second chamber to isolate the first chamber and the second chamber, wherein, the isolation wall is integrally formed with the cylinder body; a first piston; a second piston; a first rod provided in connection with the first piston; a second rod provided inside the cylinder body, being in connection with the first piston, wherein, the second rod is supported in the isolation wall; and a cap provided at a first opening of the cylinder body, the first opening is at an end of the second chamber along the axial direction. A brake-by-wire system including the master cylinder is also disclosed herein.

An installation structure of a pedal stroke sensor of an integrated dynamic brake (IDB) system is disclosed. The IDB system includes a hydraulic block, a hydraulic pressure generator, and an electronic control unit (ECU). The hydraulic block includes not only a master cylinder connected to a brake pedal but also a plurality of passages and valves needed to adjust a brake hydraulic pressure. The hydraulic pressure generator includes a motor that is connected to the hydraulic block and operates by an output signal of a detection sensor for sensing displacement of the brake pedal, thereby generating brake hydraulic pressure. The ECU controls the motor and the valves based on pressure information and pedal displacement information. The installation structure of the pedal stroke sensor includes a magnet installed in a piston that slidably moves within the master cylinder by interacting with the brake pedal. The detection sensor includes a first sensor and a second sensor that are spaced apart from each other by a predetermined distance in a movement direction of the piston in a manner that the first and second sensors detect a magnetic flux density of the magnet in response to movement of the piston.
