  • Patent number: 11236734
    Abstract: This Angular Momentum Engine 2 in this patent application uses three simple systems: angular momentum, centripetal force, and relative motion to convert a rotational centripetal force to a linear centripetal force. This Angular Momentum Engine 2 is an ‘add-on’ to any existing vehicles propulsion system. Centripetal force cannot accelerate a vehicle as once this centripetal force reaches a vehicles ‘net force resistance’, the resistance of a physical object to any change in velocity, the centripetal force becomes tangential. This Angular Momentum Engine centripetal force can only equal a vehicles' ‘net force resistance’, therefore acceleration is left to the exiting propulsion system, such as a series or parallel automotive hybrid systems, or electric vehicles as examples. Centripetal forces are exponential, as its force is proportional to the square of the speed, while acceleration forces are linear giving this patent design an exponential edge over existing propulsion systems.

    Abstract: A clutch assembly for disposition in a motor vehicle drive line includes an internal reaction force circuit. The clutch assembly includes a multiple disc friction clutch disposed adjacent an operator assembly which selectively applies force to the friction clutch to selectively transfer torque therethrough. The clutch components are disposed between fixed stops on an elongate member which functions as a reaction force member to self-contain the reaction force from the clutch operator. The clutch finds application in motor vehicle drive line components such as a rear (secondary) axle in which it is disposed in pairs to independently control torque supplied to each axle and in applications where it is advantageous to contain or ground the reaction force generated by and associated with the clutch operator compactly within the clutch structure rather than its housing.

  • Patent number: 5445546
    Abstract: A shift assistor for a shifting mechanism of a watercraft outboard drive provides a simply structured and compact device which establishes engagement of the transmission under a resilient force and disengagement under a positive force. The shift assistor includes a shift plunger which is coupled to a shift operator and an actuator casing which is coupled to the transmission. A detent coupling is directly operable between the plunger and the casing to couple the plunger to the casing when the transmission is engaged either in the forward or reverse drive directions, and to release the plunger from the casing when the transmission is disengaged.

For driving the two winding spindle wheels (22, 23) peripherally, the apparatus (1) has a drive wheel (21) which can be motor-driven in opposite directions of rotation. For alternatively driving the two winding spindle wheels (22, 23) the drive wheel is displaceable between two operating positions. When its direction of rotation is changed, the drive wheel is automatically displaced from one to the other operating position, whereby for its displacement the drive wheel (21) rolls peripherally along an associated rolling surface (73) which is provided on a roller member (51).
