An angle drive socket tool that provides interchangeable multi-angular socket for inserting a tool. A drive shaft has a driver engagement end and a magnetic enabled concave fastener receiving end with retainment and drive engagement pins. A driver component having a spherical insert end with a drive pin engagement channel extending there about an oppositely disposed drive configured input end, such as a hex socket suitable to drive a fastener of choice as illustrated in the preferred embodiment.

A shaft-hub connection system with angular play for bidirectional transmission of driving torque, comprising a shaft, a hub provided with a hole inside which the shaft is accommodated, and elements for connection which are interposed between the hub and said shaft. The connection elements comprise at least one functional assembly which comprises a slot in which a corresponding coupling element is accommodated so that it can move and is adapted to assume alternately a first position, in which it is retracted within the slot, a second position, in which it protrudes partially with respect to it along a first orientation, and a third position, in which it protrudes partially with respect to it along a second orientation, elastic compression elements interposed between the slot and the coupling element, a first seat and a second seat for the abutment of the coupling element.

A phase adjuster assembly configured to adjust a phase between a driving component and a driven component of an internal combustion engine is generally provided. The assembly includes an input gear assembly comprising an input gear configured to engage a driving component, and a spline carrier. An output gear assembly includes an output gear configured to engage a driven component, and a drive plate configured to drivingly engage with the spline carrier. Various components disclosed herein are formed as stamped sheet metal components. Additionally, various connections between adjacent components are provided via relative uncomplicated processes, such as welding.

A phaser system is provided. The system includes a first gear connected to a first plate, and a second gear connected to a second plate. A phaser assembly includes at least one piston plate, and axial displacement of the at least one piston plate is configured to adjust a phase between the first gear and the second gear. A hydraulic fluid actuator assembly is also provided that includes a hydraulic fluid circuit including an advance chamber defined on a first side of the at least one piston plate and a retard chamber defined on a second side of the at least one piston plate. A valve selectively pressurizes the advance chamber or the retard chamber such that the at least one piston plate is axially displaced.

In a vehicle cam damper structure, a drive shaft includes a cam damper at a midway portion thereof. The cam damper integrates a cam reception portion with a cam via a shaft member. The cam reception portion is connected relatively rotatably with the shaft member. The cam and the shaft member, while being integrally rotatable, are connected with each other axially slidably. The shaft member includes an enlarged-diameter portion. An elastic member that presses the cam toward a side of the cam reception portion is disposed between the enlarged-diameter portion and the cam. An outer cylinder extends across the cam reception portion and the shaft member. A drive-side shaft and a driven-side shaft of the drive shaft are each connected with corresponding one of the cam reception portion and the shaft member.

A connection unit connected to a rotation body by fitting to transmit a rotation force includes a rotation shaft, having a width across flat portion; and a core member, having fitting portions fitted to the rotation body in a direction perpendicular to the width across flat portion and an annular portion that the width across flat portion are slidably fitted, and held on the rotation shaft to be capable of moving relatively in two dimensions along the width across flat portion while rotating integrally with the rotation shaft. Accordingly, generation of vibration or noise can be prevented, and easiness of assembly work, cost reduction, miniaturization and the like can be achieved.
