Abstract
A limited slip differential for a motor vehicle having a hydraulic medium plenum and pickup tube assembly which draws hydraulic medium from an axle sump by a vacuum generated by a hydraulic pump and transports the hydraulic medium to a hydraulic pump intake sump reservoir, the hydraulic medium plenum pickup tube assembly having a cross-sectional configuration which maintains the desired hydraulic medium flow rate, while being “thin” in at least one direction to filter out particulate contamination.
Claims17
A hydraulic medium plenum and pickup tube assembly for hydraulic medium filtering for a motor vehicle limited slip differential, said hydraulic medium plenum and pickup tube assembly comprising a hydraulic medium pickup tube having a cross-sectional configuration which has a cross-sectional dimension in a first direction which is significantly less than a second cross-sectional dimension in a second direction which is substantially perpendicular to said first direction to filter particulate contamination from the hydraulic medium while maintaining the desired hydraulic medium flow rate.
A hydraulic medium plenum and pickup tube assembly for hydraulic medium filtering for a motor vehicle limited slip differential, the motor vehicle limited slip differential having a hydraulic medium sump containing hydraulic medium, the hydraulic medium plenum and pickup tube assembly comprising:
- a hydraulic medium pickup tube having a cross-sectional configuration which has a cross-sectional dimension in a first direction which is significantly less than a second cross-sectional dimension in a second direction which is substantially perpendicular to the first direction to filter particulate contamination from the hydraulic medium while maintaining the desired hydraulic medium flow rate, the pickup tube having an inlet end and an outlet end, the inlet end being submerged in the hydraulic medium.
A hydraulic medium plenum and pickup tube assembly for hydraulic medium filtering for a motor vehicle limited slip differential, the motor vehicle limited slip differential having a hydraulic medium sump containing hydraulic medium, the hydraulic medium plenum and pickup tube assembly comprising:
- a plenum portion having a central aperture therein;
- and
- a hydraulic medium pickup tube having a cross-sectional configuration which has a cross-sectional dimension in a first direction which is significantly less than a second cross-sectional dimension in a second direction which is substantially perpendicular to the first direction to filter particulate contamination from the hydraulic medium while maintaining the desired hydraulic medium flow rate, the pickup tube having an inlet end and an outlet end, the inlet end being submerged in the hydraulic medium, the pickup tube extending outwardly from the plenum portion.
