摘要： A braking force control apparatus has an upstream braking actuator for generating an upstream pressure common to four wheels, a downstream braking actuator individually controlling braking pressures supplied to braking force generating devices of the wheels using the upstream pressure, and a control unit. When the downstream braking actuator is abnormal and the upstream pressure can be supplied to the braking force generating devices, but a braking pressure of any one of the wheels cannot be normally reduced, the control unit selects higher one of the target braking pressures of the left and right front wheels and higher one of the left and right rear wheels, determines lower one of the two selected target braking pressures as a backup target upstream pressure, and controls the upstream braking actuator such that the upstream pressure becomes the backup target upstream pressure.

摘要： A cylinder apparatus for a brake may include: a piston configured to reciprocate in a cylinder body; a rod coaxially coupled to the piston; a stopper disposed in the cylinder body with the rod penetrated and inserted into the stopper; and an elastic member disposed between the piston and the stopper and configured to elastically support the piston in a direction away from the stopper. The piston and the rod may be integrally formed by injection molding.

摘要： Provided is an electric booster which can be downsized by enhancing space efficiency while reducing the effect of a magnetic field from outside on a magnetic sensor by means of a magnetic shield. The stroke amount of an input plunger 29 connected to a brake pedal 6 is detected by a stroke detection sensor. The operation of an electric motor is controlled by controller on the basis of the stroke amount of the input plunger to thrust a primary piston through a ball screw mechanism, and brake fluid pressure is thus generated by a master cylinder 4. The stroke detection device uses a Hall IC to detect magnetic flux densities from first and second magnet members mounted on the input plunger to obtain the stroke of the input plunger. The first and second magnet members and the Hall IC are disposed inside a linear-motion member formed of a cylindrical magnetic body of the ball screw mechanism to be magnetically shielded.

摘要： A modular non-linear spring system capable of simulating traditional brake pedal feel when incorporated into a hydraulic and/or electro-hydraulic vehicle braking system. The system can include a first spacer having a top surface and a bottom surface and an optional second spacer having a top surface and a bottom surface. In one arrangement, a first mechanical spring is in abutting engagement with the top surface of said first spacer, a second mechanical spring is in abutting engagement with the bottom surface of said first spacer and the top surface of said second spacer, and an optional third mechanical spring is in abutting engagement with the bottom surface of said second spacer. The springs are arranged to be progressively compressed using a brake pedal of the braking system.

摘要： 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.

摘要： A hydraulic operating device comprises a base member, an operating member, and a piston. The base member includes a first end portion, a second end portion, a cylinder bore, a first hose-attachment hole, and a second hose-attachment hole. The second end portion is opposite to the first end portion. The first hose-attachment hole is configured to be in fluid communication with the cylinder bore. The second hose-attachment hole is configured to be in fluid communication with the cylinder bore. The operating member is pivotally coupled to the base member at the first end portion about a pivot axis. The first hose-attachment hole and the second hose-attachment hole are provided closer to the pivot axis than the second end portion.
