The invention relates to a motorized road vehicle having a braking system for actuating braking elements assigned to the wheels of said vehicle, and control elements for controlling the operation of the braking system, which system includes a hydraulic manual braking circuit. The invention is characterized in that the braking system comprises a complementary, electrically controlled, hydraulic circuit, and the control elements comprise an electric automatic braking control system for generating main or complementary braking set values, which are transmitted to the complementary hydraulic circuit.

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.

A vehicle braking control device is capable of further raising the speed at which vehicle vehicle-body deceleration increases when automatic braking processing implementation begins. Provided as a braking control device is a control device comprising: an acquisition unit that acquires an indicator; and a braking control unit that starts the implementation of automatic braking processing if a determination is made, on the basis of the indicator, that an automatic braking condition has been established. In the automatic braking process, the braking control unit restricts the supply of brake fluid to wheel cylinders corresponding to the rear wheels, and supplies brake fluid to wheel cylinders corresponding to the front wheels to increase the pressure of the wheel cylinders, thereby increasing the braking power for the front wheels and also giving the rear wheels braking power corresponding to the driving amount of a motor for parking.

A first valve module (4000) includes a valve block and circuits for controlling hydraulic pressure to parking brake and differential lock actuation circuits of a vehicle. An extension flowpath (4010) has an extension inlet and outlet opening respectively through an interface surface and further external surface of the valve block. A second module (1000) may be connected to supply a first service brake circuit, the circuits of the first module, and, via a second service brake outlet communicating with the extension inlet, a second service brake circuit. In a method, first and second valve blocks with internal flowpaths formed respectively by machining and by casting are assembled together with valves to define valve modules (4000, 1000) having respective, first and second functional circuits. The first valve block includes an extension flowpath. The second module supplies pressure to the first functional circuit and the extension flowpath of the first module.

A brake system for a motor vehicle, having a first hydraulic brake device configured to brake wheels on a first axle of the motor vehicle, a first control unit configured to control the braking operation of the wheels on the first axle; and a second hydraulic brake device configured to brake the wheels on a second axle of the motor vehicle, and a second control unit configured to control the braking operation of the wheels on the second axle. The first control unit is coupled with the second control unit via a communication channel. The first control unit and the second control unit are each configured to receive data that are relevant for the control of the braking operation, the first control unit furthermore being configured to transmit a data signal on the basis of the received data via the communication channel to the second control unit.

A braking system for use with a dual landing gear aircraft. The braking system pairs outboard brake control into an outboard brake system control unit (BSCU) and inboard brake control into a second inboard brake system control unit (BSCU). Each BSCU is designed with two independent control lanes in which the forward wheel set is paired in one control lane and the aft wheels are paired onto the other. Alternate braking is provided via an alternate brake module installed in a fore-aft wheel pairing.

A brake pedal unit includes a housing defining a bore formed therein. An input piston is slidably disposed in the bore. The input piston is connected to a brake pedal such that engagement of the brake pedal causes movement of the input piston within the bore of the housing of the brake pedal unit. The brake pedal unit is defined to be in an at rest position when the brake pedal in not engaged causing movement of the input piston. A primary piston is slidably disposed in the bore for pressurizing a primary chamber. A primary passageway permits fluid communication between the primary chamber and the reservoir, wherein fluid flow through the primary passageway is blocked when the brake pedal unit is in the rest position. A secondary piston is slidably disposed in the bore for pressurizing a secondary chamber. A secondary passageway permits fluid communication between the secondary chamber and the reservoir, wherein fluid flow through the secondary passageway is blocked when the brake pedal unit is in the rest position

In order to offer an improved brake device without vacuum booster, in the case of which brake device the zero point of the cylinder piston remains as far as possible permanently within defined narrow tolerances and at the same time the impact noise is reliably reduced, it is proposed that the stop disk is elastically reversibly compressible in an axial direction over a defined compression travel and has the compression travel delimited, the delimitation being defined in a travel-controlled manner.
