摘要： A coil assembly for a solenoid valve includes a bobbin formed from an electrically insulative material. A bore extends axially through the bobbin. A first flux ring having a sleeve extending axially from an annular base is mounted upon a first end of the bobbin with the sleeve extending into the bobbin bore. Similarly, a second flux ring also having a sleeve extending from an annular base is mounted upon a second end of the bobbin that is opposite from the first flux ring with its sleeve extending into the bobbin bore. The flux rings are formed from a magnetically permeable material that has a high heat conductivity. Magnet wire is wound upon the assembled bobbin and flux rings to form the coil assembly.

摘要： A brake booster for a brake system of a vehicle, wherein the brake booster is in fluid communication with a source of pressurized fluid. The brake booster includes a housing having a bore formed therein and a conduit formed therein being in fluid communication with the bore and the source of pressurized fluid. The brake booster includes first and second pistons slidably disposed within the bore of the housing. The bore, the first piston, and the second piston define a fluid chamber in fluid communication with the conduit formed in the housing, wherein the volume of the chamber is defined by the position of the first piston relative to the second piston. The brake booster further includes a valve selectively preventing fluid flow in a direction from the chamber to the source of pressurized fluid via the conduit.

摘要： A control valve includes a magnetic pole member. An armature is slidably supported relative to the magnetic pole member for movement between a fully open position and a closed position. A biasing spring is disposed between the magnetic pole member and the armature for forcing the armature away from the magnetic pole member. A coil is placed about the magnetic pole member and the armature for inducing a magnetic field for moving the armature toward the magnetic pole member. One of either of the magnetic pole member or the armature has a recess for non-contactingly receiving the other when the armature moves between the fully open and closed positions. The control valve can be embodied as a normally open valve or a normally closed valve. The use of dual lateral poles and triple lateral poles create a flat magnetic force versus travel curve thereby allowing for greater proportional control of the valve. Additionally, the use of double lateral gaps and triple lateral gaps respectively results in force increases of 21% and 12% respectively. Compounding the force increases results in a net additional force of 36%.

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.
