摘要: A variable valve actuation assembly (41) to be mounted about a camshaft (43) including a concentric portion (47) and an eccentric portion (49) which orbits the axis of rotation (A1) of the camshaft and defines an axis (A2). The assembly (41) includes a secondary cam member (51) surrounding the concentric portion (47) and including a cam surface (59,59L). The assembly (41) also includes an arm assembly (61) which surrounds the eccentric portion (49), and defines a longitudinal axis (A3) perpendicular to, and intersecting the axis (A2). The arm assembly (61) can pivot about a pin (71), and at the opposite axial end is pivotally connected to the secondary cam member (51) by means of a pin (75). Rotation of the camshaft (43) causes the arm assembly (61) to pivot about the pin (71) in one direction, rotating the cam member (51) to lift the valve (17), then pivot in the other direction, rotating the cam member (51) in the opposite direction.

摘要: A ball ramp mechanism is used to apply an axial force in the same regardless of the direction of the flow of torque whenever there is relative rotation between an input shaft and an output hub using unidirectional grooves in both a control ring and an activation ring where a first index plate limits the rotation of the activation ring and a second index plate limits the rotation of the control ring relative to the input shaft. An electrical coil is used to induce a magnetic field in a coil pole to magnetically couple a coil armature to an intermediate plate and the intermediate plate to an activation plate to energize the ball ramp mechanism.

摘要: A compression release engine brake assembly adapted for use with an internal combustion engine, and an exhaust valve (29) operable to open in a normal exhaust lift event (FIG. 9) and in a brake lift event (FIG. 15). The engine includes an exhaust valve actuating mechanism (23,31,37) for imparting reciprocal movement to said exhaust valve (29) in response to rotation of a cam shaft (11) including a cam profile (13), a normal lift portion (17) and a brake lift portion (19). The assembly includes a lost motion device (75) moveable between a normal lost motion condition (FIG. 4) and an actuated condition (FIG. 14) in response to movement of an input member (91). An energy storage spring (117) is operable, after being compressed to an energy storage condition (FIG. 12) to be able to bias the input member (91) toward a second position, effecting the actuated condition of the lost motion device (75). A latching mechanism (99,103-113,129,131) is operable to first displace the energy storage spring (117) to a compressed condition, and then release it just before the cam follower (21) traverses the brake lift portion (19), in response to the pivotal movement of the rocker arm assembly (23) which comprises part of the exhaust valve actuating mechanism.

摘要: A vehicle driveline clutch using a ball ramp actuator supplying a clamping force on a clutch disc in response to an electromagnetic field where the clutch clamping force is maintained and increased with clutch slip using a plurality of one-way clutches acting in a pair of planetary gearsets with a one-way clutch acting on each planet gear and supported on a carrier ring which is frictionally connected to a ball ramp control ring upon energization by a clutch coupling with an electrical coil thereby creating relative rotational motion between the control ring and an actuation ring causing a plurality of rotational elements to travel along identical opposed variable depth ramps thereby creating an axial separation force between the control ring and the actuation ring generating the clamping force on the clutch disc. The clutch coupling includes a cone clutch where the clutch extension portion of the cone clutch has a plurality of drive flanges thereon that engage mating drive channels formed in the control ring to transfer rotational motion from an output element to the control ring through the clutch coupling without misalignment of the cone clutch.

摘要: A closed hydraulic system (22) is provided for transmitting steering movement to a rear wheel steering assembly (16) in response to steering movement of a front wheel steering assembly (14). The front wheel steering assembly is controlled by a steering wheel (18) and a power steering assembly (20). The closed hydraulic system (22) includes a pump assembly (56) and an actuator assembly (58) connected together by conduits (60,62) to define closed fluid flow branches (164,166) for moving a piston (112) in the actuator assembly in response to movement of a piston (78) in the pump assembly. Movement of the actuator piston is transmitted to the rear wheel steering assembly via first and second cam assemblies (122,124) which effect same direction rear wheel steering for rather small front wheel steering angles and which effect opposite direction rear wheel steering for greater front wheel steering angles. Pump assembly (56) includes first and second neutral valves (92,94) for intercommunicating opposite sides of the pump piston (78) with a chamber ( 83) when the piston is in a neutral position. System (22) also includes a reservoir (68) disposed above the normal fluid level of the system and exposed to atmospheric pressure.

摘要: A ball ramp mechanism is used to apply a clamping load to a clutch pack to rotationally couple an input shaft to an output shaft. The ball ramp mechanism is comprised of a control plate having a control extension radially extending therefrom and an activation plate having an activation extension radially extending therefrom and an intermediate plate disposed between the control extension and the activation extension where the control extension and the activation extension and the intermediate plate are frictionally rotationally coupled upon application of an electromagnetic field generated by a stationary coil acting through a rotating coil armature to activate the ball ramp mechanism. A gap sleeve contacts the control plate and the activation extension to limit the separation between the control extension, the intermediate plate and the activation extension. The activation plate is mounted to the input shaft through a first one-way clutch and the coil armature is mounted to the input shaft through a second one-way clutch when the first one-way clutch is oriented opposite to the second one-way clutch.
