Abstract:
1. A transmission for use in mobile power equipment, the transmission comprising: a housing having a first housing member connected to a second housing member along a joint to form a sump; an input shaft extending into the first housing member; a hydraulic mounting member disposed in the sump and comprising a first running surface having a first pair of ports and a second running surface having a second pair of ports in fluid communication with the first pair of ports; a pump rotatably disposed on the first running surface and engaged to and driven by the input shaft; a motor rotatably disposed on the second running surface of the hydraulic mounting member and in fluid communication with the pump, wherein the second running surface of the hydraulic mounting member is generally perpendicular to the first running surface of the hydraulic mounting member and lies between the pump and the motor, the second running surface having at least a first portion located above the first running surface; a pump displacement control mechanism rotatably supported in part by the hydraulic mounting member and in part by the first housing member, wherein the hydraulic mounting member rotatably supports the pump displacement control mechanism in a support surface formed opposite the first portion of the second running surface; and a motor shaft driven by the motor and having a proximal end rotatably supported by the second running surface and extending therethrough to overlap the support surface in the axial direction of the motor shaft, and a distal end.
