  • Patent number: 10316901
    Abstract: According to one or more embodiments, a clutch pack includes a first set of clutch plates arranged in an alternating configuration with a second set of clutch plates. The first set of clutch plates has a plurality of friction pads made of friction material and defining channels in the friction material. The channels are configured to allow lubricant to flow between the friction pads. Each of the friction pads defines a groove in the friction pad. The groove is disconnected from the channels. The groove thereby creates a flow induced high pressure region forcing the first set of clutch plates to a center between the second set of clutch plates.

  • Patent number: 10309467
    Abstract: A clutch is controlled to increase torque capacity of the clutch when fluctuations in torsional torque generated in a power transmission route between the clutch and a drive wheel are larger than a specified value during deceleration traveling. Accordingly, engine brake whose magnitude corresponds to an increased amount of the torque capacity of the clutch is actuated. Therefore, the fluctuations in the torsional torque can be suppressed by the engine brake.
