摘要： A hydraulic fluid circuit for a power transmission device includes a first hydraulic circuit segment fluidly decoupled from a second hydraulic circuit segment. A hydraulic pump includes a first fluidic pumping element and a second fluidic pumping element. The first fluidic pumping element fluidly communicates with the first hydraulic circuit segment. The second fluidic pumping element fluidly communicates with the second hydraulic circuit segment. The first fluidic pumping element is controllable to a first pump operating point to achieve a preferred high fluidic flow rate in the first hydraulic circuit segment. The second fluidic pumping element is controllable to a second pump operating point to achieve a preferred high fluidic pressure in the second hydraulic circuit segment.

摘要： In transmissions having input clutches, a lever arm configured as a second class lever is pivoted at one end, applies force to a clutch bearing near its middle and is acted upon by a linear actuator at its opposite end. The present invention relates to mechanisms for adjusting the location of the pivot to compensate for clutch wear. The fixed pivot is replaced by a linear one way clutch mechanism. As the clutch facing wears and the clutch is activated, an extension of the actuating lever arm abuts a stationary stop beyond the one way clutch pivot which translates the pivot point provided by the one way clutch mechanism toward the clutch to reduce pre-travel and compensate for clutch facing wear. Hydraulic and spring biasing of the pivot point are also disclosed.
