Abstract: A transmission system efficiently performs efficiently and also provides the ability to perform full-power shifts. For example, a secondary clutch actuator, independent of fluid actuation, may eliminate the need for a pump to continuously provide high pressure during regular vehicle operation such that high pressures are only required during a shift event. This eliminates the need for energy at the pump to maintain application of the clutch, thereby allowing such energy to be used of other systems in the EV or to facilitate increased vehicle range.

Abstract: A transmission utilizes oscillating torque to vary the mechanical power transmitted to a load. The transmission has a rotatable input member and a rotatable mass. The transmission also has a member with an eccentric offset, with the rotatable mass rotatably coupled to the offset and being eccentric with respect to the offset. The input member is coupled to the rotatable mass by a linkage so that the rotation of the input member causes the rotatable mass to rotate and apply centrifugal force to the member with the eccentric offset. First and second one-way clutches are coupled between the eccentric offset member and an output member. The first one-way clutch drives the output member in one direction and the eccentric offset member is driven in the one direction and the second one-way clutch prevents the output member from rotating in the other direction.

Abstract: A torque transmission device for providing steplessly variable torque conversion. The torque transmission device has a set of unidirectionally-rotatable, slotted levers radiating from a first axis, capable of engaging a torque output ring which is also rotatable on the first axis. An abaxial ring, which has studs that operate in the slots of the levers, is rotatable on a parallel second axis which can orbit the first axis. Torque input induces the second axis to orbit the first, and the force of orbital motion bears, through the abaxial ring, on at least one lever in a direction opposite its rotatable direction, holding it fixed, and also bears on at least one other lever in a direction that coincides with its rotatable direction, causing it to rotate. The fastest-rotating lever engages and drives the torque output ring. Varying the distance between the first and second axes varies the torque conversion ratio.

Abstract: A constant power mechanical transmission with seamless, ripple free, infinitely variable torque multiplying outputs comprises an input shaft and an output shaft. The input shaft is coupled to a pair of oscillating levers whereby rotation of the input shaft causes oscillation of the oscillating levers in opposite directions. The oscillating levers are linked to the output shaft with one-way clutches in order to cause rotation of the shaft upon movement of the oscillating levers. The rotational speed of the output shaft can be infinitely varied by changing the throw of the oscillating levers.

Abstract: A transmission has only a single, minimal orbiter in which an input gear and an output gear, each being connected to separate input and output shafts, are interconnected through an orbiting cluster gear that meshes with only the input and output gears. The cluster gear is carried by a web that is itself rotated by a hydraulic control motor through a first clutch. When rotation of the web is prevented, rotation of the input gear produces rotation of the output gear at a predetermined reduction of the input drive, this gear reduction being continuously diminished proportional to the speed of rotation of the web in a first direction. When the vehicle reaches highway speeds, the control motor is disconnected and a second clutch is activated to connect a predetermined overdrive that is located between the engine drive and the transmission rather than being conventionally positioned between the transmission and the final output shaft.

Abstract: A variable-ratio transmission device. A first translational member is pivotally intercoupled to a first rotational member by at least one connecting arm. The connecting arm has a first portion pivotally connected to the first translational member at a first pivot point, and a second portion pivotally and adjustably connected to the first rotational member at a first radial attachment point removed from the center of rotation of the first rotational member. The first radial attachment point and the center of rotation thereby define a first attachment radius. The location of the first radial attachment point with respect to the first rotational member is variable to thereby increase and decrease the first attachment radius, which in turn modifies a ratio of movement between the first rotational member and the first translational member.
