摘要:
The present invention is a configurable trailer hitch that provides an extended towing position for transferring a tractor force to a load, and a retracted storage position for safely stowing the hitch under a towing vehicle. The trailer hitch has a spring loaded retaining pin which engages a hitch receiver when the trailer hitch is placed in the towing position, and a storage latch adapted to hold the hitch receiver when the trailer hitch is placed in the storage position.

A wind turbine includes a closed loop hydrostatic transmission. The rotor is directly coupled to a low-speed high torque hydraulic motor, which is pressure-reversible to act as a pump. A variable displacement, pressure compensated hydrostatic transmission receives the hydraulic fluid output and drives a generator. The hydrostatic transmission and the generator may be compactly located in the nacelle of wind turbine tower.
