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 vehicle braking system includes a wheel cylinder, a master cylinder including a master cylinder piston operable to translate between an unactuated position and an actuated position in a first mode of operation, a brake pedal operable to transition between an extended position corresponding to the unactuated position of the master cylinder and a retracted position corresponding to the actuated position of the master cylinder, and a booster located between the master cylinder and the brake pedal. The master cylinder is operable to selectively transfer a braking force from the brake pedal to the wheel cylinder in the first mode of operation. The booster is operable to hold the brake pedal in the retracted position in a second mode of operation without user input and without associated braking.

摘要： A pedal assembly comprises a pedal arm; a pedal plate provided on a second end of an elongated lever structure of the pedal arm; a vehicle mounting bracket; and a retainer. The retainer is installed on the pedal arm and is configured to operatively connect the pedal arm and an end portion of an operating member so as to transmit the movement of the pedal arm between a first and a second arm position to a functional system. The retainer is in an open position for insertion of the end portion of the operating member therein. The retainer is configured to move or to be movable from the open position to a closed position in which the retainer retains the end portion of the operating member received therein. The retainer is movable from the open position to the closed position by insertion of the operating member therein.

摘要： An electromechanical brake assist system driven by an electric motor cooperating with a master cylinder and having, along the axis of actuation, a helper piston in the shape of an axial sleeve solidly connected with a guide bracket and having a threaded surface. A nut, fixed in translation but free to rotate, has interior threads that complement those of the helper piston, which it receives, and exterior teeth that cooperate with the drive motor. A plunger piston carries a drive base so it can be pushed by the piston. Its other extremity is connected to the control rod, formed from a body and a head. The body has a crimping area and the head has a sleeve with an extremity that can be crimped along the crimping area.

摘要： 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.

摘要： A brake device and an automatic driving vehicle using the same are provided. The brake device includes an electrically controlled brake assembly, a mechanically controlled brake assembly and a shaft. The electrically controlled brake assembly has a main body and a brake control link. The shaft is connected between the electrically controlled brake assembly and the mechanically controlled brake assembly. The mechanically controlled brake assembly includes a pedal, an elbow, a brake link group and a brake pump. The first end is connected to the pedal, and the fulcrum is between the first end and the second end and is located close to the second end. The brake link group is connected between the elbow and the brake control link. The brake pump has an adjustable rod, and one link of the brake link group is connected to the adjustable rod.

摘要： A brake operating device to improve a brake feeling by a simple structure without a hydraulic source or an electric power source. A first reaction force establishing mechanism as an elastic member establishes the reaction force against the pedal force applied to the brake pedal. A second reaction force establishing mechanism increases the reaction force when depressing the brake pedal. The first reaction force establishing mechanism and the second reaction force establishing mechanism are arranged coaxially in series.

摘要： A hydraulic master apparatus for a hydraulic brake or clutch of handlebar-guided vehicles having a handlebar tube includes a support, a lever pivotally connected to the support, a hydraulic cylinder sized to fit in the handlebar tube and having a piston, and a pulling device configured to exert a pulling force on the piston when the lever is actuated. The apparatus also includes a grip width adjusting apparatus, by which a distance between the support for the lever and the hydraulic cylinder is adjusted to adjust a grip width. Also included is a cover that, responsive to being connected in the handlebar tube, defines with the hydraulic cylinder in the handlebar tube a compensating chamber therebetween.

摘要： A braking device for a hydraulic motor vehicle braking system having an electromechanically driven booster stage and a ball screw drive. In order to provide a braking device which is of particularly compact, cost-effective and weight-saving construction and has short pedal strokes, and an easily adjustable pedal characteristic curve, at the same time enabling effective direct action in case of failure of the booster stage and comfortable haptic feedback at the pedal during normal operation, the actuating force from a piston rod is introduced into the spindle, wherein the piston rod can be moved axially to a limited extent relative to the spindle and a spring element is inserted in the flow of force of the actuating force between the piston rod and the spindle, which spring is compressed axially when the actuating force is introduced.

摘要： Provided is a braking device capable of suppressing an overshoot or undershoot in output pressure. This vehicle braking device is configured such that a pressure adjustment unit has a piston which is driven by the difference between force corresponding to pilot pressure and force corresponding to output pressure, and a control unit estimates, on the basis of a stroke-related value regarding the amount of movement of the piston, the amount of change of the output pressure that changes even after switching from pressure increase control or pressure reduction control to holding control of the output pressure, and controls a valve unit on the basis of the estimated amount of change of the output pressure.
