Abstract: A monitoring and protecting circuit for an electronic antiskid braking system of a vehicle having a plurality of wheels, each wheel having a speed sensor unit providing a direct-current speed signal representative of the rotational speed of this wheel. The circuit includes means for selecting the speed signal having the higher level, apparatus for selecting the speed signal having the lowest level and apparatus for comparing these levels. The output of the comparing apparatus is transmitted through time-delay apparatus to a switching device controllable for inhibiting the operation of the antiskid braking system, whereby this system is inhibited when the comparing apparatus delivers an output for a time duration exceeding a predetermined amount. Apparatus are provided for preventing the inhibition of the antiskid braking system when the brakes of the vehicle are being applied, and when the discrepancies between the rotational velocities of the wheels are due to skidding during acceleration of the vehicle above a predetermined rate.

Abstract: The hydraulic power control device comprises a boost piston whose movements depend on the pressure of fluid contained in an actuating chamber, said pressure being controlled by a distributing valve connected to a pressure fluid source and to a reservoir. The valve is operated by a push rod through the intermediary of a lever connected to a double sensor responsive to the relative movement of the valve and of the boost piston. The lever presents a first end on which the sensor is pivoted and a second end pivotably secured to a sliding pin mounted in housing of the control device.

Abstract: The invention relates to an operating device for a vehicle braking system comprising a master-cylinder and a set of wheel brakes. The device comprises a hydraulic portion having an annular boost piston and a mechanical portion connected to an energy accumulator device having a coil spring. The mechanical portion includes two pivoting arms, one of which cooperates with said boost piston by the intermediary of a rod whose free end projects through an annular unlocking piston. When pressure in the master-cylinder reaches a predetermined value, the unlocking piston shifts towards the left of the figure thereby causing fluid-tight engagement between boost piston and a shoulder provided on the rod, and unlocking the energy accumulator device by rotation of the arms. Upon release of the master-cylinder, fluid flowing back from the wheel brakes biases the boost piston to the right until the different parts of the device reach a position in which the energy accumulator device is again locked.

Abstract: An adaptive braking system for a set of vehicle wheels, of the type comprising a fluid pressure source, braking apparatus associated with the set of wheels, and control apparatus for controlling the fluid pressure acting on the braking apparatus. The fluid pressure supplied to the braking apparatus is automatically controlled by the control apparatus in successive stages of pressure increase and pressure decrease separated from one another by intervals during which the pressure is kept constant. More particulary, a stage of pressure increase is controlled after an interval whenever the deceleration of a wheel has been decreasing or has remained constant during this interval, and a stage of pressure decrease whenever the deceleration has been increasing during the interval.

Abstract: A constant-velocity joint of the type having torque transmitting members in the form of two interlacing forks and bearing balls situated between the prongs of the fork, the balls being movable in grooves provided in the mutually opposite surfaces of the fork prongs. To prevent relative axial motion of the forks, a flexible tie has each of its ends connected to a respective fork in the central region of the joint. In a preferred embodiment, the tie is a spring steel wire coiled to have closely wound turns. When the joint is bent, the tie is curved in the region of its center with sufficient flexibility to prevent jamming of the joint. The flexible tie is more economical to manufacture than the prior art connecting means such as those including a ball and socket device whose center acurately coincides with the joint''s bending center.
