A portable information handling system includes a motorized hinge that rotates first and second housing portions between open and closed positions and a clutch hinge that manages torque during rotation of the first and second housing portions. A clutch of the clutch hinge couples to an axle with a compressive mechanism and a clamping mechanism that combine to apply a total torque that resists rotation of the first and second housing portions. The clamping mechanism couples to the axle from within a clutch housing and the compressive mechanism inserts over the axle to compress at opposing sides of the clutch housing.

In examples, a cone clutch assembly includes an inner cone member rotationally coupled to a first shaft, the inner cone member defining a first friction surface; and an outer cone member rotationally coupled to a second shaft, the outer cone member defining a second friction surface opposing the first friction surface. The inner cone member and outer cone member may be selectively engaged and disengaged from another. When the inner cone member is engaged with the outer cone member, the first friction surface of the inner cone member frictionally engages the second friction surface of the outer cone member such that rotational motion is transferred between the inner cone member and the outer cone member. The inner cone member includes at least one hole including an inlet near a front edge of the inner cone member and that extends through the inner cone member adjacent to the first friction surface.

A synchronizer is provided for torsionally connecting a gear to an axially aligned shaft. The synchronizer includes a hub connected with the shaft, a sleeve having an inner diameter with spline teeth for torsional connection with the hub being axially movable upon the hub, a blocking ring torsionally connected on the hub having an angular lost motion relationship with the sleeve, the blocking ring having at least a first annular conical friction surface orientated radially inward and axially toward the hub and a second annular conical friction surface oriented radially inward and axially outward from the hub, the blocking ring having blocking cogs preventing axial movement of the sleeve toward the gear when the gear is in a non-synchronous condition, and an engagement ring for fixed connection with the gear, the engagement ring having a complementary annular conical friction surfaces.

A drive system for a hybrid vehicle having an internal combustion engine includes an electric motor and a clutch device which has a frictional locking element and a positive locking element that is connected parallel to the frictional locking element. The clutch device is configured to couple the internal combustion engine into the drive system and to be switched into at least the following states: a) open positive locking element and closed frictional locking element when starting and/or synchronization of the internal combustion engine, b) closed positive locking element and closed frictional locking element or closed positive locking element and open frictional locking element when the internal combustion engine is running and synchronized such that an internal combustion engine drive output action is generated, and c) open positive locking element and open frictional locking element when the internal combustion engine is stopped such that purely electric motor drive of the vehicle is provided.

A hybrid module for a vehicle arranged in a drivetrain between a drive unit, particularly an internal combustion engine, and an output, wherein an electric machine is provided, a rotor of the electric machine is connected to the output, and a clutch is provided between the drive unit and the electric machine, characterized in that the clutch is formed as a cone clutch.

A friction surface clutch having two conical friction surface pairs each with an inner friction surface element and an outer friction surface element, wherein the inner friction surface element is mounted axially displaceable with respect to a rotational axis, and wherein a frictionally locking connection is set up and canceled in a manner which is dependent on the axial displacement position of the inner friction surface element. The inner friction surface element is coupled to a separate transmission element such that the inner friction surface element and the transmission element can be rotated jointly about the rotational axis, with the coupling being set up via a bearing contact between a guide surface on the inner friction surface element and a countersurface on the transmission element.
