Abstract: A variable camshaft timing system for an internal combustion engine comprising a housing having an outer circumference for accepting drive force, a rotor for connection to a camshaft coaxially located within the housing capable of rotation to shift the relative angular position of the housing and the rotor, a locking pin, and a centrifugal valve. The locking pin is slidably located and radially moveable in a radial bore from a locked position in which the inner end fits into the recess defined by the housing, locking the relative angular position of the rotor and housing, to an unlocked position in which the inner end does not engage the receiving hole defined by the housing. The centrifugal valve is in fluid communication with an inlet line coupled directly to an engine oil supply controlling flow of oil to the locking pin.

Abstract: In a variable cam timing (VCT) system that has a crank shaft coupled to at least one cam shaft. The system has at least one timing gear associated with the crank shaft or a cam shaft. The timing gear includes at least two groups of toothlike projections including a first group having a first distance to the center of the wheel, and a second group having a second distance to the center of the wheel. The first distance is different from the second distance. Whereby torsional energy for torque actuated purposes is increased for the VCT system. The system may further include a resonator which is positioned upon the at least one cam shaft, the resonator including at least one mass and at least one elastic element. Whereby torsional oscillation of the at least one cam shaft at a predetermined engine speed range is increased.

Abstract: A hydraulic rack-style tensioner includes two concentric pistons in the bore of a tensioner housing. The lower piston which occupies a generally lower position in the housing has conventional ratchet teeth on an outside surface. The ratchet teeth form a rack which are engaged by a pawl. An upper piston occupies a generally upper protruding position in the housing. A chamber is defined between the upper piston and the housing, or between the upper piston and lower piston. Pressurized fluid in the chamber between the upper and lower pistons act to cushion impact of the rack and pawl mechanism when high loads from an associated tensioner arm and chain cause the upper and the lower pistons to be forced back toward the tensioner housing.

Abstract: The present invention relates to a torsionally compliant sprocket system which absorbs crankshaft torsional vibrations and minimizes their transfer to other components in the engine system. In particular, the present invention includes a sprocket formed with an elastomeric member located between hub and rim portions. The hub has splines which cooperatively engage with keyways formed in the rim portion through the elastomeric member. A method of forming the compliant sprocket includes forming the hub and rim portions and injection molding an elastomeric material into a gap between the hub and rim portions. While in the mold, heat is applied to the sprocket assembly. The elastomeric member is thus vulcanized in place, creating a one-piece compliant sprocket.

Abstract: A hydraulic tensioner is designed for low cost and ease of manufacturing. A piston housing has a bore and a bore cup member received within the bore. A piston is slidably received within the bore cup member, forming a high pressure fluid chamber with the bore cup member. The piston housing can be constructed of inexpensive materials such as aluminum or plastic. The piston and bore cup member are constructed of drawn metal. A single channel connects the pressure chamber to an external source of fluid, and a single valve system regulates the flow of fluid into the pressure chamber. The inexpensive materials and simple design provide for a low cost hydraulic tensioner.

Abstract: An on demand vehicle 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.

Abstract: A variable valve timing system includes a toothed rotating sleeve, a rack, and an actuator. The rack has a first end, a second end with a plurality of teeth in meshing contact with the teeth of rotating sleeves of the valve and being linearly moveable to rotate the sleeves. The actuator includes a housing, a control valve, and at least one check valve. The housing slidably receives a piston coupled to the rack separating a chamber in the housing into first and second chambers. The control valve selectively directs fluid from the first to the second chamber or vice versa. When the rack is shifted linearly by vibrational impulses from the engine, the piston moves linearly within the housing, pressurizing the first or the second chamber and under control of the control valve, fluid recirculates from the first or the second chamber to the other chamber.
