摘要： A brake apply system includes a pressure charging module having a bore carrying a pumping piston that has a base piston surface and an augmentation piston surface. The pressure charging piston separates the bore into an input chamber adjacent the base piston surface and an output chamber adjacent the augmentation piston surface. A suspension damper is hydraulically connected to the input chamber of the pressure charging module, preferably through a continuously open fluid communication circuit. A wheel brake is hydraulically connected to the accumulator output chamber through a selectively open fluid communication circuit. An accumulator is interconnected in the selectively open fluid communication circuit and maintains a pressure charge that is generated by movement of the pumping piston as effected by operation of the damper and that is delivered to the wheel brake through the selectively open fluid communication circuit Through this mechanism the initial pressurization rate of the brake apply system is increased.

摘要： A brake system includes a pedal feel emulator and a master cylinder with a damping mechanism having a damping piston. When the emulator piston is moved from the at-rest position, fluid is displaced from the emulator through a compensation port and through a flow restrictive orifice in the damping piston to the reservoir. Flow rate of the fluid is dependent on the apply rate of the brake pedal. When the brake pedal is applied relatively slowly, sufficient flow volume will occur through the flow restrictive orifice and the damping piston will remain unmoved. As apply rates increase, a sufficient pressure differential will eventually be established across the damping piston to cause it to move. Damping piston movement compensates for rapid fluid displacement out of the variable chamber and enables a desirable pedal feel characteristic where pedal force increases relatively slowly as pedal velocity increases relatively rapidly. As the damping piston movement provides increasing volume, the pressure differential drops across the damping piston and it will cease to move as flow is accommodated solely through the flow restrictive orifice. As this occurs, pedal force will increase more rapidly providing a two-stage damping characteristic.
摘要翻译： 制动系统包括踏板感觉模拟器和具有阻尼机构的主缸，该阻尼机构具有阻尼活塞。 当仿真器活塞从静止位置移动时，流体从仿真器通过补偿端口并通过阻尼活塞中的限流孔移动到储存器。 流体的流速取决于制动踏板的施加率。 当制动踏板相对缓慢地施加时，通过限流孔会发生足够的流量，并且阻尼活塞将保持不动。 当施加率增加时，将最终在阻尼活塞上建立足够的压力差，以使其移动。 阻尼活塞运动补偿了可变腔室中的快速液体位移，并且能够提供令人满意的踏板感觉特性，其中踏板力相对较慢地增加，因为踏板速度相对快速地增加。 随着阻尼活塞的运动提供增加的体积，压力差通过阻尼活塞而下降，并且当流仅容纳通过限流孔口时，其将停止移动。 当发生这种情况时，踏板力将增加更快，提供两级阻尼特性。

摘要： Improved control for a hydraulic system useful in automotive braking applications, particularly in dry interface automotive braking applications, includes the use of a valve for holding pressure in a hydraulic system constant while relieving the pressure load on the pressure source. Preferably, the valve is a normally-open solenoid valve that is closed and opened in response to a desired pressure being sensed at a pressure actuated mechanism, such as a brake caliper. The use of the improved control for a hydraulic system improves brake response times during ABS applications, and increases the energy efficiency and life expectancy of the pressure providing motor.

摘要： An electro-hydraulic brake apply system includes an emulator that effects pedal feel simulation by allowing compliance at a selective variable rate. This provides a vehicle driver with the preferred pedal travel and feedback characteristics of a conventional master cylinder/power booster apply system. As a secondary function, the emulator is utilized to latch the modulator. This locks the modulator apply piston in place when electrical power is removed from the drive motor. Further, the emulator operates to hydraulically isolate the master cylinder from the wheel brakes during normal system operation.

摘要： A rotary actuated braking system includes a motor driven shaft that operates two pairs of piston pumps and an allocation valve which, in combination with a single solenoid valve, effects ABS operation of the braking system. A combination of pressure operated control valves and pressure operated release valves for each control wheel brake respond to operation of the rotary actuator and solenoid valve to effect ABS pressure release and reapply from the corresponding wheel brake. A power boosted master cylinder provides base brake operation independent of the rotary actuator effected ABS operation.

摘要： A power brake apply system includes a master cylinder having a piston for generating fluid pressure within a braking circuit. A boost valve assembly is mounted adjacent the master cylinder and carries a slidable spool that selectively closes off a normal path of communication between a fluid reservoir and the boost chamber of the master cylinder in response to the manual actuation of the master cylinder's piston as effected through a pressurized braking circuit. After closure of communication between the reservoir and the boost chamber a power fluid supply is opened to the boost chamber to provide power assist in the actuation of the master cylinder's piston.

摘要： A polygonal device for teaching students who prefer kinesthetic learning methods is presented in which the polygonal device can represent two-dimensional polygons of varying shapes and sizes. One or more of the sides, or legs, of the polygonal device are extendable, and the angles of the polygonal device may be manipulated to a desired angle. The devices presented include, but are not limited to, triangles, quadrilaterals, parallelograms, rectangles, squares, trapezoids, and kites. In each of these devices, the legs of the device are non-detachable, i.e. the device does not come apart during normal manipulation and operation.

摘要： An electro-hydraulic actuator for a motor vehicle brake-by-wire brake system including a housing, a piston bore in the housing, a T-shaped piston in the piston bore, and an electric motor connected to the piston through a speed reducer. The T-shaped piston includes a disc-shaped head in the piston bore and a tubular stem perpendicular slidable in and out of the piston bore through a sealed guide in the bottom of the piston bore. The top side of the piston head opposite the stem constitutes a large effective area of the piston for rapidly expelling a relatively large volume of fluid from the piston bore in a low pressure interval of operation the actuator. When the fluid pressure in the piston bore exceeds a transition pressure, a transition valve opens a bypass passage to the piston bore behind the piston head so that the same fluid pressure reacts against the bottom side of the piston head around the stem. A high pressure interval of operation of the electro-hydraulic actuator then ensues in which the effective area of the piston is reduced to the area of the cross-sectional profile of the stem.
