  • Patent number: 11047427
    Abstract: The disclosure relates to a disk (38) for a disk clutch (26) comprising an annular base element (76) which has a toothing (78) with multiple teeth (80) for achieving a rotary driving engagement with a disk carrier (34), wherein the base element (76) has at least one hardened region (96) in which the base element (76) is designed as harder than in the tooth flank regions (98, 100) of the teeth (80). In addition, the disclosure relates to a disk clutch (26) with such a disk (38), a double clutch device (2) with such a disk clutch (26), and a method for producing such a disk (38).

  • Publication number: 20130237352
    Abstract: A transmission mechanism with a pair of selectively engageable clutch systems is disclosed that has an upstream gear ratio and a downstream gear ratio that combine to provide an effective gear ratio. A different clutch drive member is associated with an input side of each of the pair of clutch systems. The clutch drive members are driven for rotation by an engine input member. The upstream gear ratio is determined by the gear ratio between the engine input member and one of the clutch drive members. Output sides of each of the clutch systems drive an associated one of a pair of non-coaxial layshafts. Pinions are located on and selectively driven by the layshafts. A countershaft is spaced from both of the layshafts, and has a plurality of gears. Each of the gears is driven for rotation by one of the pinions of the layshafts. The downstream gear ratio is determined by the gear ratio between the selected pinion and the intermeshed gear.

  • Publication number: 20100288592
    Abstract: The present disclosure sets forth a one-way clutch. The one-way clutch can function with one or no races as opposed to conventional prior art one-way clutches. In so doing, the overall size and weight requirements of the one-way clutch are drastically reduced, which in turn drastically reduces the overall size and weight requirements of the transmission and vehicle employing the transmission as well. The present disclosure also provides a one-way clutch having an outer race provided by axially spaced plates. An inner race is rotatably mounted with respect to one of the plates and the inner race has a ratchet surface. Ratchet pawls are pivotably mounted with respect to the plates and have unidirectional engagement with the ratchet surface of the inner race. In addition to reducing material and labor production costs, such lessened size and weight penalties translate into higher transmission efficiency and better vehicle fuel economy.

  • Publication number: 20100092297
    Abstract: A synergistic blade and hub structure for a cooling fan. Helical gussets are provided which proceed from the central hub member adjacent one blade member to the trailing edge of an adjacent blade member. The helical gussets provide structural load paths as well as aerodynamic flow guides. The helical gussets extend axially rearwardly to the trailing edges of preceding blade members and provide structural attachments between the leading and trailing edges of adjacent blade members. Hollow triangular structures are also provided on the rear of the fan structure and the triangulation area provides superior stiffness.
