Abstract: A motor vehicle vacuum driven hydraulic balance system includes a housing. A shaft rotatably supported in the housing has a longitudinal bore to deliver oil flow to a plurality of ports created in the shaft. A vacuum flow passage communicates with both the longitudinal bore and an oil sump. A first delivery passage is created in a portion of the housing, the first delivery passage in direct communication with the longitudinal bore. An electrical oil pump pumps oil from the oil sump to the longitudinal bore through the first delivery passage. Axial rotation of the shaft creates a partial vacuum in the longitudinal bore acting to vacuum drag oil from the oil sump through the vacuum flow passage to the longitudinal bore in addition to a volume of the oil delivered to the longitudinal bore by the electrical oil pump.

Abstract: A weld joint includes a first component of a first material and a second component of a ductile second material dissimilar from the first material. A planar face of the first component abuts a planar face of the second component. A “V” shaped weld groove is created in the first component defining a first groove end where a substantially planar groove face of the first component intersects a plane defined by the planar face of the second component below an end face of the second component. A slot is created below the groove end in the planar face of the second component having a closed end facing toward the end face of the second component and extending away from the planar face of the second component at an angle measured with respect to a central longitudinal axis of the slot.

Abstract: A drive unit, method, and control system are provided that warm drive unit fluid in a drive unit having a main pump, a scavenge pump, and an electric motor for powering an axle of a vehicle. The control system and method are configured to fill a main sump of the drive unit with drive unit fluid to a predetermined fill level. In a warm-up mode, the method and control system operate the electric motor to heat the drive unit fluid within the main sump while the vehicle is stationary and the electric motor is at least partially disposed in the drive unit fluid within the main sump. Further in the warm-up mode, the method and control system are configured to operate the scavenge pump to pump the drive unit fluid from the main sump into an auxiliary reservoir after the drive unit fluid has been heated by the electric motor.
