  • Patent number: 10151353
    Abstract: A mechanical clutch such as a dog clutch includes a plurality of balls or rollers disposed in a carrier and positioned between opposed sets of straight cut teeth extending from opposed drive and driven elements. A ball or roller is positioned between each adjacent pair of teeth such that the torque load is transferred from the tooth on a first or drive element, through the ball or roller, to an adjacent projection or tooth on a second or driven element. The balls or rollers are maintained in position by the carrier having an inner ring and a concentric outer ring. Greatly reduced disengagement force, even under load, is exhibited by a clutch of this configuration.

  • Patent number: 10153499
    Abstract: A bipolar plate assembly and fuel cell stack with reduced leakage and a method of assembling a bipolar plate and fuel cell stack. The bipolar plates include—in addition to reactant channels and coolant channels that are fluidly coupled to inlet and outlet flowpaths, integrally-formed seals to help reduce leakage by maintaining fluid isolation of the reactants and coolant as they flow through their respective channels and flowpaths. The size and shape of the seals promotes secure plate-to-plate contact, even during plate side-to-side misalignment that can occur when arranging the various plates into the stack.

  • Patent number: 10150463
    Abstract: A system according to the principles of the present disclosure includes a power determination module and a powertrain control module that includes a state selection module. The power determination module can estimate power required to travel at a desired speed on a roadway segment located in an anticipated path of a vehicle based upon an estimated slope of the roadway segment. The powertrain control module can control operational states of a hybrid powertrain. The powertrain control module includes a state selection module that can determine whether a current operational state is capable of producing the estimated power based upon a state of charge of a vehicle battery. The state selection module can also switch to another operational state that is capable of producing the estimated power if the current operational state is incapable of producing the estimated power.
