Hydrostatic drive losses can be significant, In wheel drives are the best option and reduce the inefficiency in a swashpalte type axial pump significantly, if compared to propshaft speeds of 3 to 4 times the RPM of wheel speeds. At speeeds below 1000 RPM and lower hydraulic drive efficiencies can exceed manual transmissions. The limked reference is a fixed displacement in wheel drive with a transformer to control pressure and volume.
We are getting a little ahead of ourselves here. Let's let the hydraulic discussion wait a while until after the dual clutch 6 speed automated manuals are presented. Thanks for the interest and responses.
