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.

摘要： A brake pedal for a motor vehicle brake-by-wire brake system including a pedal lever pivotally supported on a body of the motor vehicle, a foot pad on the pedal lever, and a compliant member having a plurality of parallel beams defining cantilever springs. A pedal force on the foot pad effects pedal travel of the pedal lever from a release position toward a brake full apply position. The parallel beams defining cantilever springs are arrayed in series between the pedal lever and the motor vehicle body and engage is series so that the effective stiffness of the compliant member increases during pedal travel. The stiffness of each of the parallel beams and the magnitudes of a plurality of clearance spans therebetween are “tuned” to yield a pedal force which initially increases slowly relative to pedal travel and then increases exponentially relative to pedal travel thereby emulating the relationship between pedal force and pedal travel of a brake pedal in a traditional motor vehicle brake system. Elastic pads on the parallel beams cushion the successive engagements of the parallel beams and blend the corresponding changes in stiffness of the compliant member.

摘要： A brake pedal for a motor vehicle brake-by-wire brake system including a pedal lever resiliently flexible in beam bending, a foot pad on the pedal lever, and a mounting for the pedal lever on a body of the motor vehicle which constitutes the pedal lever a variable stiffness cantilever spring. The mounting for the pedal lever includes a socket for an inboard end of the pedal lever, a stationary reaction surface on the body of the motor vehicle, and a pedal lever reaction surface on the pedal lever which faces and diverges from the stationary reaction surface in a release position of the pedal lever. The stationary reaction surface and the pedal lever reaction surface become progressively engaged concurrent with resilient flexure of the pedal lever in cantilever spring bending to vary the stiffness of the cantilever spring. The stationary and pedal lever reaction surfaces are contoured or “tuned” to yield a pedal force which initially increases slowly relative to pedal travel and then increases exponentially relative to pedal travel thereby emulating the relationship between pedal force and pedal travel of a brake pedal in a traditional motor vehicle brake system.

摘要： A brake pedal feel emulator includes a piston that is movable against the force of a compressible elastomeric body and fluid force. The emulator supplies conventional pedal feel and travel characteristics when the primary and secondary pistons of the brake system's master cylinder are substantially movable due to isolation of the master cylinder from the wheel brakes. The fluid force is supplied by controlling the flow of fluid from behind the emulator piston through a flow restrictive orifice to a conventional fluid reservoir on the master cylinder assembly. The emulator is operable with electric or electro-hydraulically controlled braking system.

摘要： A brake pedal assembly for a vehicle equipped with an electronic or “brake-by-wire” braking system includes a brake pedal feel emulator which mimics or emulates the pedal feel of a conventional hydraulic braking system. The brake pedal feel emulator includes a single cantilever spring which reacts against a shaped surface and is mounted such that the free end thereof applies a force to the brake pedal which varies as the point at which the spring diverges from the shaped surface changes in response to movement of the brake pedal. The free length of the spring is therefor varied as the pedal is depressed as a function of the shape of the shaped surface, so the force applied to the pedal may be designed to vary to emulate the feel of a conventional braking system.

摘要： A disc brake caliper with an integral parking brake includes a caliper housing defining a cavity therein and a piston axially translatable within the cavity and having an internal bearing surface. At least one brake pad is affixed to either the piston or the caliper housing. A parking brake mechanism is mounted within the cavity and is interposed between a portion of the housing and the piston. The parking brake mechanism includes a thrust pin substantially axially aligned with the piston and rotatable within the housing. A first radial clutch is engageable with the thrust pin, and a second axial clutch is operable upon the piston. Rotation of the thrust pin in a first direction causes engagement of the first radial clutch and of the second axial clutch causing axial displacement of the piston. Rotation of the thrust pin in an opposite direction causes disengagement of the first and said second clutches.

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.
