ELECTRIC HYDROSTATIC DRIVE MODULES FOR VEHICLES Abstract An electric-hydrostatically powered vehicle has an electric motor connected through a gear box to a hydro- static pump which powers the vehicle. The vehicle chassis includes a main frame portion and a removable subframe portion which is resiliently mounted in spaced-apart, overlying relationship on the main frame portion. The subframe provides a platform for mounting the motor, gear box and pump independently of the main frame of the vehi- cle to define a removable drive module. The subframe provides planar mounting surfaces that enable transla- tional and angular positioning of the motor and gear box in three dimensions to align their shafts. The module is preassembled by mounting the motor and gear box on the platform, aligning and connecting their shafts, and securing the motor and gear box to the platform. There- after, the module is installed as a unit into the vehi- cle, the alignment of the shafts being undisturbed. A three-point resilient mount isolates the subframe from shock and vibrations imparted in the main frame.
