Abstract: The load sensing brake proportioning valve of a vehicle comprises a first piston (14) sliding in a stepped bore made in a body, and carrying a normally open shutter (18) arranged between a source of fluid under pressure and the associated brake circuit, the first piston (14) being moveable counter to a spring (16) under the effect of the pressure of the fluid which tends to close the shutter (18), a sliding rod (24) normally bearing between a pusher (20), the position of which is a function of the load of the vehicle, and the shutter (18). The proportioning valve comprises a locking mechanism immobilizing the sliding rod (24) as soon as the pressure of the fluid in the associated brake circuit exceeds a specific threshold.

Abstract: A primary brake system operated by either one of a hand operated means and a foot operated system is mounted on one of the front and rear wheels, and a secondary brake system operated in response to the operation of the primary brake system is mounted on the other wheel. Consequently, it is possible to provide a braking-force distribution for the front and rear wheels with a predetermined common characteristic, leading to an improved brake feel. A braking-force control is provided for controlling the braking-force distribution to the front and rear wheels in accordance with the operating forces of a first input operated by the hand operated element and a second input operated by the foot operated element, so that an ideal distribution characteristic falls within a region between a first braking-force distribution characteristic for the front and rear wheels by the hand operated element and a second braking-force distribution characteristic for the wheels by the foot operated element, such region being a braking-force distribution characteristic region at a time when the hand and foot operated elements are operated simultaneously.

Abstract: A hydraulic pressure control device of a load sensing type is provided. The hydraulic pressure control device includes a spring support disposed on a vehicle body side or wheel side for supporting a suspension spring, a support member tiltably disposed in the spring support for supporting a load of the suspension spring at three support portions, and a hydraulic pressure control valve mounted on the support member for controlling hydraulic pressure supplied to a braking unit mounted on a wheel from a source for generating hydraulic braking pressure. Thus, at least a portion of the force applied to one of the support portions can be applied to a control piston of the hydraulic pressure control valve.

Abstract: A load-responsive brake pressure control device for vehicle brake systems includes a control valve actuatable by a stepped piston. The stepped piston has one surface of a larger axially effective area which is acted upon in the valve closing direction by the pressure prevailing downstream of the valve, and another surface of a smaller axially effective area which is acted upon in the valve closing direction by the pressure prevailing upstream of the valve. A load-responsive spring acts in the opening direction of the valve on a movable component of a cylinder-and-piston unit, especially on a flange of a cylinder component of such a unit, to urge the same into its initial position in which it abuts a stop surface of a support. The cylinder and piston components of the unit together define a chamber which communicates with a flow path having a stationary portion accommodating a sealing element bounding a passage of a reduced cross section. The stepped piston carries a plunger which penetrates into the passage after a predetermined amount of movement of the stepped piston in the closing direction, so as to entrap the fluid present in the chamber of the unit. Thereafter, further movement of the stepped piston in the closing direction is hindered by the pressure of the entrapped fluid, until this pressure rises to a level at which the movable component of the unit yields in opposition to the spring force. Then, the valve will close and the pressure downstream thereof will be maintained at a level determined by the ratio of the axially effective areas of the aforementioned surfaces of the stepped piston.

Abstract: A load weighing device compressively interposable between a sprung portion and an unsprung portion of a vehicle and subjectable to a compressive force of a degree corresponding to the load condition of the vehicle. The weighing device, which is adapted for interposition in a fluid pressure circuit, includes means for converting the compressive force to a proportionally reduced force and valve means operable by the reduced force for effecting transmission of a fluid pressure control signal of a degree inversely proportional to the degree of the compressive force. The weighing device may be modified to transmit a fluid pressure control signal directly proportional to the compressive force reflecting the load condition.
