摘要： A vehicle braking system master cylinder that can handle pressure pulses within the brake fluid of a vehicle braking system without the destruction of components internal to a master cylinder. A vehicle braking system master cylinder that allows for component subassembly external to the master cylinder and is self-aligning when assembled. Finally, a vehicle braking system master cylinder that allows for variable travel of the primary piston and the secondary piston within the master cylinder and greater fluid flow in the vehicle braking system.

摘要： The present invention provides a sensor system for detecting lining wear and fluid level in a dry interface corner actuator for a single wheel brake including a reservoir assembly. The reservoir assembly includes a reservoir for containing fluid for the actuator and a sensor assembly positioned in the reservoir having a single set point to indicate both low reservoir fluid level and a need for brake lining replacement.

摘要： A brake master cylinder-sensor system and method are provided. The system includes a master cylinder, a piston slidably positioned in the master cylinder, a magnet positioned on the piston, and a sensor disposed on the master cylinder. A change of piston linear position causes a linear change in a magnetic field position sensed by the sensor, and a brake control signal proportional to the change of piston linear position is generated. A method of operating a brake master cylinder-sensor system includes applying a brake pedal force, changing a piston linear position within a master cylinder, determining a change in a linear magnetic field position proportional to the change of the piston linear position, and generating a brake control signal based on the change in the linear magnetic field position.

摘要： A brake master cylinder reservoir diaphragm has a vent slit therein to operate as a vent valve to equalize air pressure when a pressure differential is impressed across the diaphragm as the brake fluid level in the reservoir changes. The vent slit has an omega or bell curve shape so that the movable valve member is the tongue-like part formed on the inner curvilinear part of the curved vent slit. The tongue valve member acts as a cantilever supported valve which bends at its base to open in either direction under a differential pressure acting on one side or the other of the diaphragm. The opening and closing action of the tongue valve member can be fine tuned by modifying the bending resistance of the base of that member. Such modifications can include a partial base slit extending only part way into the thickness of the base to form a groove in alignment with the straight ends of the omega slit and located between them. Such a groove may be provided on one or both sides of the base, and the depth and length of any such groove can be controlled to fine tune the bending characteristics of the base. The base slit may also be formed entirely through the diaphragm material. The length of the straight ends of the omega slit may also be changed to have a modifying effect on the base bending characteristics.

摘要翻译： 制动主缸储存器隔膜具有一个通气孔，用于作为排气阀工作，以当储层中的制动液液位变化时跨越隔膜施加压力差来平衡空气压力。 排气狭缝具有ω或钟形曲线形状，使得可动阀构件是形成在弯曲排气狭缝的内曲面部分上的舌状部分。 舌阀构件用作悬臂支撑阀，其在其基部处弯曲，在作用在隔膜的一侧或另一侧上的压差下沿任一方向打开。 舌阀构件的打开和关闭动作可以通过改变该构件的底座的抗弯曲性来微调。 这样的修改可以包括仅部分地延伸到基座的厚度中的部分基部狭缝，以形成与欧米茄狭缝的直端对准并位于它们之间的凹槽。 这样的槽可以设置在基座的一侧或两侧上，并且可以控制任何这种槽的深度和长度以微调底座的弯曲特性。 基座狭缝也可以完全通过隔膜材料形成。 欧米茄狭缝的直端的长度也可以改变为对基底弯曲特性具有修改效果。
