Abstract: A hydraulic tensioner is provided with a plunger slidably fitted in a cavity in the tensioner housing and biased in a protruding direction by a spring and fluid. An integral inlet check and pressure relief valve is positioned in the cavity and permits fluid to only flow into the cavity and thereby protrude the plunger but not out of the cavity until a high pressure condition is reached whereupon fluid is relieved out of the cavity back to the fluid source. The integral inlet check and pressure relief valve includes a check spring biasing a valve member a against a pressure relief disk that is biased against the valve member by a pressure relief spring.

Abstract: A transmission for an engine or motor with a reduced package size and increased efficiency comprising: an input sprocket, an output sprocket, a chain, and a planetary gear set. The output sprocket is drivingly connecting to the input sprocket through the chain. The output sprocket has a hollow center portion that receives the sun gear of the planetary gear set. The planetary gear set also includes at least two planet gears meshed with the sun gear which are mounted to a fixed planet carrier for driving a differential with a ring gear portion. When the input sprocket is rotated in a first direction, the chain drives the output sprocket and the sun gear in the first direction, and the sun gear drives the planet gears to rotate in a second direction, opposite the first direction, driving the ring gear portion and differential in the second direction.

Abstract: A phaser for an engine having at least one camshaft comprising a housing, a rotor, a control valve, an actuator, and a pulse wheel. The rotor connects to a camshaft coaxially located within the housing. The housing and the rotor define at least one vane separating a chamber in the housing. The vane is capable of rotation to shift the relative angular position of the housing and the rotor. The control valve is received by the rotor and directs fluid to the chambers of the phaser. The actuator positions the control valve and has at least one integrated position sensor, such that electrical connections for the actuator and the integrated position sensor are made through one connection, decreasing leakage of fluid from the phaser. A pulse wheel is mounted on the phaser for rotation therewith and in alignment with the integrated position sensor of the actuator.

Abstract: A hydraulic tensioner includes a plastic cap vent or check valve at the top of the piston. Oil and air that pass through the top end of the piston accumulate in the space between the plastic cap and the piston. The plastic cap moves small distances in the axial direction to permit the escape of air and oil through the plastic cap to atmosphere. A low rate spring may be used to cause the plastic cap to move away from the piston.

Abstract: An on demand venicle drive system monitors vehicle performance and operating conditions and controls torque delivery to the vehicle wheels. The system includes a plurality of speed and position sensors, a transfer case having primary and secondary output shafts driving primary and secondary axles and a microcontroller. The sensors include a vehicle speed sensor, a pair of primary and secondary drive shaft speed sensors, and brake and driveline status sensors. The transfer case includes a modulating electromagnetic clutch controlled by the microcontroller which is incrementally engaged to transfer torque from the primary output shaft to the secondary output shaft. When the speed of either the front or the rear drive shafts overruns, i.e., exceeds, the speed of the other drive shaft by a predetermined value related to the vehicle speed, indicating that wheel slip is present, clutch current is incrementally increased to increase clutch engagement and torque transfer to the secondary axle. When wheel slip is reduced below the predetermined value the current to the clutch is incrementally reduced. The method of operating such a system is also described.
