Definitions

  • the present disclosure relates to a vehicle driveline component having a friction clutch.
  • Friction clutches are commonly employed in various vehicle driveline components, such as transfer cases, electric drive units, power takeoff units, torque transfer couplings, and axle assemblies to selectively transfer rotary power between two components of the vehicle driveline component.
  • Such friction clutches commonly include a clutch hub, a clutch drum, a clutch pack and a pressure plate.
  • the clutch pack includes first clutch plates, which are axially slidably but non-rotatably coupled to the clutch hub, and a plurality of second clutch plates that are interleaved with the first clutch plates and axially slidably but non-rotatably coupled to the clutch drum.
  • Each of the first clutch plates and/or each of the second clutch plates can include an annular steel plate and a friction material that is adhered to the annular steel plate.
  • the pressure plate can be axially slidably but non-rotatably coupled to either the clutch hub or the clutch drum and can be translated along the rotational axis of the friction clutch to selectively compress the clutch pack to permit torque transmission between the first and second clutch plates.
  • the torque curve associates the position of the pressure plate (relative to a kiss point) with the amount of torque that the friction clutch is able to transmit.
  • the friction clutch can be integrated into the vehicle driveline component without a need for empirically determining the actual torque curve of the friction clutch and thereafter calibrating the controller that operates the actuator of the friction clutch to compensate for differences between the actual torque curve and the design target torque curve.
  • FIG. 1 an exemplary prior art friction clutch 2 is illustrated in cross-section and under a predetermined load. Bending of various components within the friction clutch 2, including a conventional pressure plate 4, can cause some of the clutch plates 6a, 6b in the friction clutch 2 to bind rather than slide in an axial direction. When such binding occurs, the clutch plates 6a, 6b that experience binding transmit relatively less torque than the clutch plates 6a, 6b that do not experience binding so that the actual torque curve of the friction clutch 2 deviates from the design target torque curve.
  • the present disclosure provides a vehicle driveline component that includes a friction clutch.
  • the friction clutch has a clutch hub, a clutch drum, a clutch pack and a pressure plate.
  • the clutch hub defines a plurality of first spline teeth while the clutch drum defines a plurality of second spline teeth.
  • the clutch pack has a plurality of first clutch plates and a plurality of second clutch plates. The first clutch plates engage the first spline teeth to axially slidably but non-rotatably couple the first clutch plates to the clutch hub.
  • the second clutch plates are interleaved with the first clutch plates and engage the second spline teeth to axially slidably but non-rotatably couple the second clutch plates to the clutch drum.
  • the pressure plate is non-rotatably but axially slidably engaged to one of the clutch hub and the clutch drum.
  • the pressure plate has a hub portion and a flange that extends radially outwardly from the hub portion.
  • the pressure plate is movable along a rotational axis of the one of the clutch hub and the clutch drum to compress the clutch pack to frictionally engage the first and second clutch plates to one another.
  • a plurality of apertures are formed in the flange.
  • the present disclosure provides a method for forming a friction clutch.
  • the method includes: developing a first friction clutch having a clutch hub, a clutch drum, a clutch pack and a first pressure plate, the clutch hub defining a plurality of first spline teeth, the clutch drum defining a plurality of second spline teeth, the clutch pack having a plurality of first clutch plates and a plurality of second clutch plates, the first clutch plates engaging the first spline teeth to axially slidably but non-rotatably couple the first clutch plates to the clutch hub, the second clutch plates being interleaved with the first clutch plates and engaging the second spline teeth to axially slidably but non- rotatably couple the second clutch plates to the clutch drum, the first pressure plate being non-rotatably but axially slidably engaged to one of the clutch hub and the clutch drum, the first pressure plate having a first hub portion and a first flange that extends radially outwardly from the first
