  • Patent number: 8707826
    Abstract: An axle having a variable volume sump. The axle includes an axle housing that defines a gear chamber and a separate reservoir. The gear chamber and the reservoir are in fluid communication with each other via an opening. A regulator is located adjacent the opening. The regulator is operable to assume a first closed position that obstructs the opening when a temperature in the axle is below a predetermined value, and is also operable to assume a second open position that places the gear chamber and the reservoir in fluid communication via the opening when the temperature is above the predetermined value.

  • Publication number: 20040150208
    Abstract: A vehicle structure includes a combination of hydro-formed, generally tubular shaped rails joined by an overlapping joint to a two-piece cross member. The overlapping joint is formed between a rail aperture and the cross member. To retain the structural strength lost by removing material from the rails, a weld joint is formed about the total perimeter of contact between the rail aperture and the cross member. The cross member includes a shoulder area formed to nest within the rail aperture. The two-piece cross member assembly reduces total parts while providing a plurality of cross member geometries and the necessary tolerance flexibility at the rail connections. The cross member is formed of two generally C-shaped members having butted or overlapping mating surfaces joined by a perimeter weld joint.
