Abstract: A method for controlling a process for manufacturing a bevel gear includes forming, via a first process, a ring gear and determining a first set of parameters associated with the ring gear, and forming, via a second process, the pinion gear, and determining a second set of parameters associated with the pinion gear. The ring gear and the pinion gear are paired, and a single-flank test is executed on the paired ring gear and pinion gear to determine a third set of parameters. The paired ring gear and pinion gear are assembled into a final assembly, and an end-of-line noise/vibration analysis of the final assembly is executed. The noise/vibration analysis, the first set of parameters, the second set of parameters, and the third set of parameters are evaluated, and one of the first process, the second process, the pairing process, and the assembly process are adjusted based thereon.

Abstract: A brake component for retarding a rotor includes a wearable friction segment having a thickness, wherein the friction segment is configured to be pressed into contact with the rotor. The brake component also includes a first resistive sensor having an electric resistance and a feature determinative of the electric resistance. The first resistive sensor is mounted on the friction segment and includes an electric connection for communication with an external device. The feature is configured to wear along with the friction segment thereby increasing the electric resistance of the first resistive sensor. A braking system employing the friction brake component to retard rotation of a wheel and for decelerating a motor vehicle is also disclosed.

Abstract: A mechanism to vary the duration and lift of a valve in an internal combustion engine, wherein a lever engaging a camlobe is rotated about a fulcrum by rotation of the camlobe; the lever possessing a member to actuate a valve; the member to engage a valve being articulated with respect to the lever, and the fulcrum possessing means to displace the valve actuating member when the lever is rotated; the displacement of the valve actuating member actuating a valve. Rotation of the fulcrum of the lever alters the point in lever rotation at which the valve actuating member is displaced to actuate the valve, and determines the extent of that displacement, so that the duration and lift of the vlave may be varied relative to duration and lift of the camlobe.

Abstract: A mechanism for combining, so as to reconcile in a dynamically acceptable manner, the valve actuating displacement of a pair of camlobes rotating at variable relative phasings so as to vary the duration of a valve; the mechanism comprising a first lever having a first cam follower to engage a first camlobe, a second cam follower to engage a second camlobe, and a fulcrum to rotatably engage a means to actuate a valve; the means to actuate a valve comprising variously i) a bucket tappet having a fulcrum to rotatably locate the first lever, ii) a second lever rotating about a fulcrum, having a fulcrum to locate rotatably the first lever, and extension/s to engage operatively a valve/s.

Abstract: A device for varying steplessly, throughout the operating range of an internal combustion engine, the duration of the processes of induction and exhaust, and the lift of the valves associated with these processes; the device employing, within a four valve combustion chamber, a pair of valves for each of the functions of induction and exhaust; each pair of valves being driven by a different camshaft; for each valve, a rotatable drum of common axis with the camshaft, and having a valve actuating rocker arm pivoted at one end within the drum; wherein angular rotation of the drum causes the cam to reciprocate the rocker arm, and therefore, the valve, at a point earlier or later in cam rotation; the combination, for instance, of an advanced opening point of the first valve, and a retarded closing point of the second valve, giving an extended duration of the process associated with the two valves.

Abstract: A device for varying optimally, throughout the operating range of an internal combustion engine, the duration of the processes of induction and exhaust. The device employing, within a common combustion chamber, two valves for each of the processes of induction and exhaust; each of the two valves being driven by a different camshaft; the two camshafts so employed being capable of variable angular indexing with respect to each other, and with respect to crankshaft revolution, by means of a camshaft indexing variator; the variable indexing so achieved causing variable indexing of the two valves relative to each other, whereby, for instance, one valve of a pair may be caused to open at an advanced indexing, relative to crankshaft revolution, and the other valve to open at a retarded indexing, relative to crankshaft revolution; the advanced opening point of one valve, and the retarded closing point of the other valve defining an extended duration of the process associated with the two valves.
