Abstract: A UTV portal axle system is disclosed, including a spindle with a housing for housing input and output drive gears coupled by one or more idler gears. The output drive gear is disposed lower than the input drive gear to provide additional ground clearance to the UTV. The king pin axis angle is substantially the same as that of a stock UTV, while maintaining a scrub radius of substantially one inch or less. This is accomplished by the lower control arm ball joint being located within a recess of the output drive gear. This allows the UTV to be properly controlled when driven at high speeds over rough or uneven terrain. The gears may be interchangeable to allow the gear ratio to be adjusted to be more suitable for use at various driving speeds. A method of changing the gear ratio is also disclosed.

Abstract: Methods and systems for controlling a hydromechanical transmission are proposed. In one example, a control method for a hydrostatic unit of a hydromechanical variable transmission (HVT) is presented, comprising controlling the hydrostatic unit via a feedforward control architecture including a non-linear, multi-coefficient model, wherein the hydrostatic unit comprises a hydrostatic pump and a hydrostatic motor. A desired differential pressure of the hydrostatic unit or a desired hydraulic pump displacement may be used as inputs for the model, where the model's output is a pressure difference for a pump control piston coupled to a swash plate of the hydrostatic unit. Use of the non-linear model permits the hydrostatic unit to be controlled based on load, speed, and/or torque, thereby increasing the adaptability of the control system.
