摘要： A control valve for controlling fluid flow in a hydraulic control unit of a vehicular brake system includes a flux tube having an end cap, a thick tube section, and a thin tube section defining an interior volume. An armature is slidably received in the interior volume of the flux tube. A coil is provided about the flux tube. A collar covers a portion of the thin tube section and is spaced from the thick tube section so that an air gap is provided between the coil and the portion of the thin tube section not covered by the collar.

摘要： This invention relates to an electro-hydraulic brake-by-wire system including a hydraulic pump and a plurality of valves to achieve a demanded braking force, and to achieve a desired brake pedal feel. The brake system includes a plurality of wheel brakes, a reservoir of hydraulic fluid, and a pump for selectively pumping hydraulic fluid from the reservoir and supplying pressurized hydraulic fluid to the wheel brakes for applying a braking force. The pump acts as a source of pressurized hydraulic fluid to the wheel brakes during normal brake apply, as well as during advanced braking functions as Antilock Braking (ABS), Traction Control (TC), or Vehicle Stability Control (VSC). An apply valve is associated with each of the wheel brakes for selectively permitting flow of pressurized hydraulic fluid from the pump to the associated wheel brake. A dump valve is associated with each of the wheel brakes for selectively permitting flow of pressurized hydraulic fluid from the associated wheel brake to the reservoir. A master cylinder is operated by a brake pedal for pressurizing hydraulic fluid. An isolation valve is associated with each of the wheel brakes for selectively preventing flow of pressurized hydraulic fluid from the master cylinder to the associated wheel brake. A sensor senses the position of the brake pedal and generates a pedal position signal representative of the position of the brake pedal. An electronic control unit receives the pedal position signal, which signal is utilized to determine a brake demand. The electronic control unit controls the operation of the pump, and the apply, dump, and isolation valves associated with each wheel brake to achieve a desired braking force at each wheel brake based on the brake demand and to regulate pressure generated by the master cylinder to achieve a predetermined relationship between the pressure generated by the master cylinder and the position of the brake pedal, whereby a desired pedal feel is achieved.

摘要： A mounting bracket for an anti-lock brake/traction control system control valve including a three point suspension. The bracket includes a base portion adapted for attachment to a vehicle. Three supporting members extend perpendicularly from the base portion. Resilient annular isolators are disposed within apertures formed through two of the supporting members. Mounting pins for securing the control valve to the bracket are carried by the isolators. A third resilient isolator having a recess formed therein is carried by the third supporting member. An extended portion of the control valve is received in the isolator recess and supported thereby. The isolators cooperate with the mounting pins and the control valve extended portion to absorb acoustical and vibrational noise.

摘要： A method for assembling a hydraulic control unit of a vehicular brake system includes the following steps of: providing a sleeve having a closed end; sliding a spring over an armature to form an armature/spring subassembly; orientating the armature subassembly to produce a normally open valve or a normally closed valve; sliding the oriented armature/spring subassembly into the sleeve; sliding a valve seat into the sleeve; crimping a portion of the sleeve onto the valve seat to form a sleeve/valve seat subassembly; inserting the sleeve/valve seat subassembly into a bore of a housing. Two additional steps can be combined with the above listed steps to provide a method of assembling the control valve subassemblies described above on a hydraulic control unit. The additional steps include: inserting the sleeve/valve seat subassembly into a bore in a housing; and pressing a coil assembly about the sleeve.
