摘要： A system suitable for positively holding an earthmover in a fixed position during excavating or loading operation, comprising a first air reservoir in communication with a parking brake via a parking control valve. A second air reservoir communicates with front and rear wheel brake cylinders via a dual brake control valve assembly and pneumatic-to-hydraulic converters. A pilot-operated source selector valve coacts with shuttle valves to normally allow communication between the brake control valve assembly and the converters and, upon application of the parking brake by the parking control valve, to place the first air reservoir in communication with the converters. Thus the actuation of the parking control valve results in the application of not only the parking brake but also the service brakes. Interposed between the converters and the brake cylinders, pilot-operated brake locking valves also respond to the actuation of the parking control valve for holding the service brakes applied by permitting fluid flow only in a direction from the converters to the brake cylinders.

摘要： A control valve for use with a force-reversing modulator in a vehicle adaptive braking system is disclosed. The valve includes a housing divided into a first section connected to one side of the modulator, a second connected to engine manifold vacuum, and a third section connected to the other side of the modulator. A solenoid valve controls communication between the first section and air at atmospheric pressure. Upon actuation of the solenoid valve, the first section is communicated to air at atmospheric pressure to thereby communicate the one side of the modulator to atmospheric air. The high pressure air in the first section acts against a piston reciprocal within the housing to open another valve connecting the third section with the second section, to thereby communicate the other side of the modulator with engine manifold vacuum. Upon deenergization of the solenoid valve, a flow-restricting orifice communicates the first and second chambers to thereby communicate the one side of the modulator with engine manifold vacuum, and the other side of the modulator is connected with atmospheric air through a bleed orifice communicating the third section with the atmosphere.

摘要： A vehicle braking system including a controller, in an initial anti-skid cycle, performs a first determination to select a high or a low control mode in accordance with wheel speed parameters. The controller in a second, or subsequent anti-skid cycle, performs a second determination to determine whether a near &mgr; test is to be performed in accordance with wheel speed parameters. The controller consequent upon selection of low control mode performs a near &mgr; test. The near &mgr; test includes performing a rise in the brake pressure and then selecting a high or low mode in accordance with the speed of the wheels resulting from the rise in brake pressure in the near &mgr; test.

摘要： An anti-lock control device of a hydraulic brake system which enables a rapid building up of braking hydraulic pressure during normal braking but, once an anti-lock control is commenced, reduces the rise of the recovery of the braking hydraulic pressure so as to optimize the same for anti-lock control. The hydraulic braking system having a pneumatic pressure source, a brake valve, converting device for receiving the pneumatic pressure supplied from the pneumatic pressure source through the brake valve and converting the received pneumatic pressure into braking hydraulic pressure, wheel cylinders for receiving the braking hydraulic pressure, and pneumatic pressure control valves for controlling the pneumatic pressure in a pneumatic pressure chamber of the converting means so as to control the braking hydraulic pressure. The anti-lock control device has a comparator for comparing the pneumatic pressure in the pneumatic pressure chamber with the output pneumatic pressure of the brake valve, and an orifice valve which is put into a passage of pressurized air between the brake valve and the pneumatic pressure control valves when the comparator has judged that the pneumatic pressure in the pneumatic pressure chamber has come down below the output pneumatic pressure of the brake valve by a predetermined value. The orifice valve reduces the rate of rise of the pneumatic pressure in the pneumatic chamber so as to correspondingly reduce the rate of increase of the braking hydraulic pressure.

摘要： Disclosed is an anti-lock control apparatus for an air over hydraulic brake system having a first air pressure line leading from a brake valve to an air master cylinder as well as a second air pressure line branching from the first air pressure line and leading to a modulator. The second air pressure line is provided with an exhaust-side check value for exhausting air from a pneumatic chamber of the modulator and an air-supply side check valve for supplying air to the pneumatic chamber. The pneumatic chamber of the modulator and the second air pressure line are adapted to hold residual pressure, thereby increasing the rising gate of the braking hydraulic pressure during braking and the falling rate of the braking hydraulic pressure during release of braking, and reducing the amount of air consumed.
