Publication number: 20200116164Abstract: An electric submersible pump (ESP) with reduced vibration is provided. In an implementation, an ESP section has radial bearings placed at shaft locations of reduced vibration to reduce wear. The locations of reduced vibration are selected to avoid areas of high vibration and vibrational waves that reinforce each other due to structure resonance and natural excitation frequencies. In an implementation, a radial bearing is positioned at a node of reduced vibration of a standing vibrational wave. In an implementation, a succession of multiple radial bearings are spaced at different intervals from each other to avoid conventional even spacing of the bearings that causes standing waves, resonance waves, and vibrational waves at natural excitation frequencies. In an implementation, a span between adjacent radial bearings is selected to spare other adjacent bearings at different spans the effects of vibrations that may extend over a range of excitation frequencies in the ESP section.Type: ApplicationFiled: August 19, 2019Publication date: April 16, 2020Inventors: Hao Lam, Arthur I.

Publication number: 20200116204Abstract: A dual plunging constant velocity (CV) drive shaft is provided for communicating rotational forces from a transaxle to a drive wheel of a vehicle. The dual plunging CV drive shaft comprises a drive shaft that transfers torque from the transaxle to the drive wheel. An inboard plunging CV joint is coupled between the transaxle and the drive shaft, and an outboard plunging CV joint is coupled between the drive shaft and the drive wheel. The inboard and outboard plunging CV joints each comprises an elongate housing that receives a CV joint coupled with the drive shaft. The inboard and outboard plunging CV joints communicate rotational forces from the transaxle to the drive wheel during vertical pivoting of a trailing arm coupled with the outboard plunging CV joint. The elongate housings allow the drive shaft to “float” longitudinally, as needed, during extreme pivoting motion of the suspension.Type: ApplicationFiled: December 13, 2019Publication date: April 16, 2020Inventor: Robby Gordon

Publication number: 20200116207Abstract: A friction plate includes a core plate defining a bore. The core plate includes an interior core surface defining the bore, an exterior core surface radially spaced from the interior core surface, a first clutch face extending between the interior core surface and the exterior core surface and facing a first direction, and a second clutch face extending between the interior core surface and the exterior core surface and facing a second direction opposite the first direction. The friction plate also includes a friction material disposed on at least one of the first and second clutch faces. The core plate also includes a fluid directing portion. A first plate thickness is defined between the first and second clutch faces. A second plate thickness is defined at the fluid directing portion. The second thickness is greater than the first thickness.Type: ApplicationFiled: October 12, 2018Publication date: April 16, 2020Inventors: Benjamin A. Siegel, Paul H. Elsesser, Richard W.

Publication number: 20200116208Abstract: An inner disc carrier (LT) for a wet-type friction clutch (K0) may have a driving toothing including ridges (S, SX) and grooves (N) for the form-locking accommodation of discs (L) of the friction clutch (K0). Each of a first group of the ridges (S) has a first opening (A1) produced in a chip-less shaping process and a section (ST) extending radially inwardly at the first opening (A1) and created during production of the first opening (A1). Hydraulic fluid supplied radially from inside the inner disc carrier (LT) from a first axial position is guided through the first openings (A1) to the discs (L). Hydraulic fluid supplied radially from inside the inner disk carrier (LT) from a second axial position is guided past the discs (L). The sections (ST) of the ridges (S) act as a damming contour for hydraulic fluid supplied radially from the second axial position.Type: ApplicationFiled: October 3, 2019Publication date: April 16, 2020Inventors: Thomas Riedisser, Steffen Einenkel, Christian Dönges, Klemens Adamski

Publication number: 20200116209Abstract: The present invention provides a self-aligning clutch release bearing in which consideration is taken for a fiber flow in a steel sheet of which a side plate is made. Specifically, the side plate is formed with cutout portions at locations where an imaginary line passing through the cutout portions and the center of an inner-diameter portion is across the fiber flow in the steel sheet of which the side plate is made. With this arrangement, the present invention makes it possible that cracks do not develop easily from the cutout portions when a flange portion is formed by means of burring process after the side plate is punched by means of blanking process. This leads to improved yield and increased strength of the side plate.Type: ApplicationFiled: June 8, 2018Publication date: April 16, 2020Inventor: Shohei FUKAMA
