Abstract: A vehicle braking apparatus that can exert high braking performance during vehicle braking is implemented by a control mode that can be realized in a braking apparatus (10) of usual hardware. In controlling the braking apparatus (10) of a vehicle, a climb rate of a wheel cylinder braking oil pressure (Pw) is decreased smaller than a climb rate corresponding to a climb rate of a master cylinder oil pressure (Pm) from a time point at which the wheel cylinder braking oil pressure (Pw) reaches a predetermined threshold value. The time point at which the wheel cylinder braking oil pressure (Pw) reaches the predetermined threshold value (P3) is estimated based on the climb process of the master cylinder oil pressure (Pm) or directly detected.

Abstract: A method and system for measuring pressure in a pressure regulation unit of a motor vehicle braking system, without using pressure sensors and having a motor pump unit with an electric motor and a hydraulic pump. The steps include producing a relative motor characteristic diagram for a series of the units. The diagram includes the data of motor-rotational-speed-dependent parameters, intensity of the motor actuation, and parameters relating to the level of the motor load. Further steps include; determining individual motor characteristic variables, determining a current rotational-speed-dependent parameter of an individual motor during the operation of the pump, and calculating a pressure which is characteristic of the braking system, by means of the diagram parameter of the individual motor and the value of the current motor actuation which determines the intensity of the motor actuation, wherein the individual motor characteristic variables are taken into account.

Abstract: The present invention relates to an electromechanical actuator comprising an electric motor (11) for driving an output shaft (4) in rotation via a reduction gear (20) and passive regulation means (30) allowing for control of the speed of rotation of the output shaft, and comprising a braking member (30), arranged between an output of the reduction gear and the output shaft to be driven, said braking member being arranged to ensure two different braking levels depending on the direction of rotation of the shaft, characterized in that the braking member is of hydraulic type and comprises fluid decantation means (33) between two chambers (34, 35) decanting under the effect of the rotation of the output shaft through a selective drawing member (41) which, depending on the direction of rotation of the actuator, opposes two distinct resistances to the decantation of the fluid from one chamber to the other.

Abstract: An ABS brake system employs two axially slidable brake discs and four brake pads that are biased to have floating light random contact therebetween in the off brake position. The ABS controller operates the brake pads with about one half of the usual brake pressure and about double the number of the usual braking and release cycles. The floating axially slidable brake discs and four brake pads have reduced residual torque drag during the brake release cycle and have reduced hystersis. The result is operation at a higher frequency and with less amplitude, than the usual sliding caliper and fixed brake system, and a resolution of a modulating scale for cycling that is usually associated with a much lower coefficient of friction surface than is actually present.

Abstract: A dynamic damper mounted on a rod-shaped oscillating member is disclosed which includes: a cylindrical metallic mass member formed of sintered metal or forging and disposed radially outwardly of the oscillating member; two elastic support members formed on axially opposite sides of the metallic mass member to elastically support the metallic mass member; and an elastic covering layer integrally formed with the elastic support member and fixed in close contact with the substantially entire area of the surface of the metallic mass member. The metallic mass member has bevels in the form of tapered cylindrical surfaces formed at radially inner edges of axially opposite end faces of said metallic mass member, respectively. Each of the bevels extends over a corresponding one of the axially opposite end faces and an inner circumferential surface of the metallic mass member to thereby chamfer the corresponding one of the radially inner edges.

Abstract: In a brake system, the actuating force of a pneumatic brake power booster, which is adapted to be independently activated, is indirectly determined. For this purpose, there is provided a pressure sensor which senses hydraulic pressure introduced into a master brake cylinder connected downstream of the brake power booster, and a differential pressure sensor which senses the pneumatic differential pressure which prevails in the housing of the brake power booster. An electronic controller calculates from both sensor signals the actuating force acting at an actuating pedal.

Abstract: A brake assembly with hydraulic boosting, comprises at least one disk brake having a fixed part (1), a caliper (3), a brake motor (82) actuated by a fluid under pressure, a master cylinder (48) and a device (15) for recovering the energy dissipated during braking. The device (15) comprises at least one energy-recovering cylinder (21) with its piston (19) which is associated with the fixed part (1) and with the caliper (3) and the working chamber of which is connected fluidly to the brake motor (82). A hydraulic booster/limiter is connected between the energy-recovering cylinder (15) and the brake motor (82), the hydraulic booster/limiter being controlled by the pressure of the fluid generated in the master cylinder (48).

Abstract: A mechanical arrangement to provide power assistance for the application of vehicle brakes with a positive shut-off of power assistance immediately upon release of the brake control by the user. The shut-off is achieved mechanically by providing pressure relief from the power assist pressure chamber by connecting a pressure relief channel between the power assist chamber and the brake fluid reservoir or by disconnecting the power piston in the power assist chamber from the main piston as soon as the brake control is released by the user.

Abstract: A brake system utilizes an auxiliary chamber defined by a control rod to control a brake assembly. The auxiliary chamber supports braking during a normal brake application and relieves the brake application forces in response to a skidding condition for a wheel assembly associated with the brake assembly.
