Patent number: 11725716Abstract: An actuator has an actuator housing engaged to a portion of a transaxle housing to define a space. A clutch assembly has a support shaft extending through the actuator housing and rotatably supporting gears in the space. At least one pin extends through one gear and a spring urges the pin into engagement with a second gear. An adjustment nut extends through the actuator housing and engages the support shaft to adjustably compress the spring. The actuator may further have an actuator housing forming a motor chamber and a gear chamber. A mounting plate detachably couples the actuator and pump housings, and the plate defines an opening through which a pump control shaft extends. A worm drive is disposed in the gear chamber and driven by an electric motor shaft, and drives a spur gear reduction, the pump control shaft being controlled by the spur gear reduction.Type: GrantFiled: October 10, 2022Date of Patent: August 15, 2023Assignee: Hydro-Gear Limited PartnershipInventors: Ivan E. Fox, Austin J. Templin, Jesse L. Probst
