Latest Patents

One of his latest patents is titled "Controls for combined hydrostatic and multiple speed range transmission." This innovative drive train includes a hydrostatic transmission unit and a multiple speed range transmission unit arranged in series between a prime mover and a primary output shaft. The variable displacement and torque transmitting capacity of the hydrostatic transmission unit are adjusted by hydraulic controls. These controls include a speed control valve for developing a differential pressure signal proportional to a desired rate of operation, a modulating valve for regulating the differential pressure signal corresponding to accelerating and decelerating operation of the transmission, a directional control valve for determining the direction of operation of the hydrostatic transmission unit, and a range selector valve for shifting the operating speed range of the multiple speed range transmission. The displacement of the hydrostatic transmission is automatically reset in response to shifting of the multiple speed range transmission. Additionally, operating speed limits are established for the drive train by an override speed control valve, which manually adjusts the differential pressure signal for reduced torque transmission when the prime mover operates below a minimum speed. A speed limiting control valve responds to operation of the prime mover above a maximum selected speed, automatically applying a brake within the drive train to supplement dynamic braking capacity.
