Abstract: The linear sensor 1 for measuring an axial path L0 of a part 2 sliding in an axial direction 20 in a frame 3 comprises a mobile part 4 cooperating with a fixed part 5, said mobile part 4 comprising: a longitudinal element 40 cooperating at one end 400 with said part 2, any translation of said part 2 in said axial path causing a corresponding displacement of its other end 401; and a magnetic field source 41 integral with the end 401, said fixed part 5 comprising a receiving means 50 for said magnetic field. The linear sensor is characterized in that said fixed part 5 comprises an angular redirection means 53 cooperating with said longitudinal element 40 and thus transforming said axial path of the end 400 into a radial path of the other end 401.

Abstract: A hydraulic braking assembly (14) for a vehicle comprising an electric servomotor (15), a master cylinder (16), a hydraulic fluid tank (17) mounted on the master cylinder, a hydraulic fluid level sensor (25) situated inside the fluid tank and monitoring the hydraulic fluid level inside the tank. The fluid level sensor is connected from the tank to the computer of the electric servomotor by a cable (26).

Abstract: The present invention relates mainly to a brake booster that is adjustable, notably in terms of the value of the jump. Advantageously, according to the invention, the “target” value for equilibrium of operation of the booster actuator is altered. A target value of a signal delivered by a position sensor is defined either by programming the electronic control unit or by selecting a coefficient in a program as a function of the braking characteristic or characteristics that it is desired to implement. Once the setpoint value has been determined, the electronic control unit commands the actuator using a setpoint value so that the actuator permanently and dynamically works toward achieving the previously defined and/or selected target value. The setpoint may be calculated as a function of torque, force, position or some other parameter. The invention applies notably to the automotive industry. The invention applies mainly to the braking industry.

Abstract: The present invention relates mainly to a braking system comprising a master cylinder comprising means of connection to a hydraulic braking circuit and means of connecting at least one chamber of the master cylinder to means of injecting brake fluid into said chamber. The main subject of the invention is a master cylinder (48) comprising at least one variable-volume chamber and one moving piston (207), the movement of which causes the volume of said chamber to vary, and means of connecting said chamber to a hydraulic braking circuit, characterized in that it further comprises means (217) of connection to a source (116) of pressurized brake fluid. The invention applies notably to the motor industry. The invention applies mainly to the braking industry.

The invention applies notably to the automotive industry. The invention applies mainly to the braking industry.

Abstract: Brake installation consisting of a master cylinder associated with a brake booster furnished with a motor driving an actuator piston and acting on the primary piston of the master cylinder by means of a reaction disk against which the piston rests. For a safety operation, the hydraulic actuator connected to the control rod actuated by the brake pedal rests on the rear face of the reaction disk. The actuator piston is combined with an auxiliary piston in order to interact with the reaction disk and it is guided by its sleeve-shaped portion in a bore of the body of the brake booster. An adapting shim is supported by the auxiliary piston in order to receive as a support the end of a rear rod, secured to the primary piston of the master cylinder. The thickness of the assembly formed by the adapting shim and the auxiliary piston is defined on mounting of the master cylinder and of the brake booster as a function of the free travel measured previously.

Abstract: The three-way valve simulator (100) for a vehicle brake servo comprises: a control piston (106); and a reaction piston (140) remote from the control piston when the simulator is at rest. It is arranged such that the control piston, under the effect of a command transmitted from outside the simulator, can be moved over a predetermined travel in the direction of the reaction piston without transmitting stress to the latter.
