  • Patent number: 7171867
    Abstract: A transmission system is provided utilizing multiple sets of clutch friction elements, each engaged to transfer torque from a torque input, such as an engine, to different gear ratios. The sets of clutch friction elements are operated simultaneously to provide a blended, gear ratio to a drivetrain. By varying the engagement of the clutch elements, and thus the proportion of the torque transferred to the gear ratio associated with each set of friction elements, an intermediate, effective gear ratio is developed. This effective gear ratio can be increased or decreased in response to external stimuli, such as vehicle and/or engine sensors, by modifying the degree of engagement of each set of clutch friction elements, and thus the proportion of torque transferred by each set of elements to its associated gear ratio.

  • Patent number: 7143882
    Abstract: Disk (1, 11) for a force transmitting aggregate, in particular for wet disk clutch, with a core plate (2, 12) exhibiting a front side (V) and a backside (R), wherein the front side (V) and/or the backside (R) exhibits a friction lining (3v, 3r, 13v) which may be provided with grooves (4a, 4b, 5a, 5b, 5c, 14a, 14b, 15a, 15b, 15c). In accordance with the invention, in the case of a friction lining with an essentially planar surface (O3v, O3r, O13v) at least one surface area (6) is provided which is raised in comparison to this planar surface (O3v, O3r, O13v) and exhibits a spring characteristic. Alternatively thereto, it is envisioned in accordance with the invention that the cross-sectional area of the lining increases or decreases in the radial direction.

  • Patent number: 6910562
    Abstract: A torsional-vibration damper includes at least one primary element and a secondary element that can be coupled to each other by a spring device, are limited in movement in relation to each other about a rotational axis, and can be brought into frictional contact with each other by a friction device. The friction device has at least two friction-surface-carrying elements rubbing against each other to which a contact-pressure force, generated by a force-generating device, can be applied to produce a frictional engagement between the two elements. The force-generating device has a mechanical actuating mechanism for generating an actuating force and a hydraulic actuating mechanism for generating a counterforce, wherein the contact-pressure force is a vector sum of the actuating force and the counterforce.
