The present disclosure relates to durability enhancement techniques for a dry-clutch vehicle transmission. A cooling system that provides a direct convective cooling path to friction surfaces is disclosed. Also disclosed is a continuously variable clutch wear compensation assembly configured to adjust the position of clutch assembly components on-demand or as needed.

Transmission with durability enhancement techniques

A system for controlling temperature of a transmission clutch includes a housing containing the clutch, a fan for circulating air through the housing and over the clutch, and a controller configured to determine an inferred temperature at a reference surface on the clutch and to actuate the fan in response to the inferred temperature.

Temperature control of dual input clutch transmission

A rotary clutch assembly for a geared power transmission mechanism comprising a friction disc clutch with driving and driven friction clutch plates, the driving plates being connected to a torque input element of the clutch assembly and the driven plates being connected to a torque output element of the clutch assembly, the clutch assembly providing a torque flow path to multiple-ratio gearing, a pressure actuator comprising first and second annular cylinder members and a movable piston member located in one of the cylinder members and cooperating with each member to define a pressure release chamber and a pressure apply chamber, the second clutch member being held axially fast on a torque input shaft for the transmission, the geometry of the cylinder members and the movable piston being sized to effect a centrifugal balance so that the clutch gain is essentially determined by the clutch commanded pressure to produce a relatively speed-independent net clutch-apply force, regardless of clutch cylinder speed.

Centrifugally balanced, pressure-operated clutch assembly

A clutch divider plate having a pair of outer plates and a pair of inner rings or members . Rings or members include several notches which allow cooling fluid or oil to pass through the plate , thereby cooling plate

Clutch divider plate

A turbine wheel for a torque converter for an automatic transmission is formed of fiber-reinforced plastic resin molded about a powder metal hub having a disc formed with corrugations extending radially from a central axis, and slots extending through the thickness of the disc at angularly spaced intervals. The plastic resin of the turbine wheel fills the spaces between the tabs, extends through the slots formed through the disc, and forms a bond to the surfaces of the disc on which it is molded.

Composite wheel and metal hub for a torque converter or fluid coupling

A turbine wheel of a torque converter for an automatic transmission is formed of fiber-reinforced plastic resin molded about a powder metal hub having a disc formed with tabs extending radially from a central flange, and openings extending through the thickness of the disc at angularly spaced intervals. The plastic resin of the turbine wheel fills the spaces between the tabs, extends through the holes formed through the disc, and forms a bond to the surface of the disc on which it is molded.
