  • Publication number: 20240030537
    Abstract: A battery box for a hybrid or electric vehicle, the battery box including a pair of longitudinal walls and a pair of lateral walls that cooperate with a drop-in floor to define an interior compartment of the battery box for holding one or more batteries. The battery box includes corner junctions where the lateral walls are attached to the longitudinal walls and further includes corner shields that are placed over the corner junctions. The corner shields are externally mounted outside of the interior compartment and provide fluid tight sealing over the corner junctions. The longitudinal and lateral walls are made of dual phase steel. The corner shields have complex corners and are therefore made of draw steel.

  • Publication number: 20240025273
    Abstract: A battery box for a hybrid or electric vehicle, the battery box including two longitudinal walls and two lateral walls that cooperate with a floor to define an interior compartment of the battery box for holding batteries. The battery box includes a mounting bracket that has a raised base, an upright segment, and a curved transition segment extending from the raised base to the upright segment. A portion of the raised base is spaced above the floor and the raised base includes a peripheral rim that is attached to the floor by spot welds. The mounting bracket includes one or more depressions that extend in a continuous manner from the raised base, across the transition segment of the mounting bracket, and across at least a portion of the upright segment. The depression(s) are designed to be spot welded to the floor and one of the longitudinal walls.

  • Patent number: 11041459
    Abstract: An exhaust gas heat recovery system includes a housing, a heat exchanger and a valve assembly. The valve assembly is disposed within the housing and includes a monolithic valve body, a moveable valve plate and a rotatable valve shaft. The valve body includes a bore, a valve seat surrounding the bore and trunnions integrally formed with the valve seat. The trunnions are diametrically opposed to each other and laterally extending outside of the housing. The valve plate coupled for rotation with the valve shaft between a first position allowing exhaust gas flow through the bore and the first exhaust gas passageway, and a second position allowing exhaust gas flow through the second exhaust gas passageway and preventing exhaust gas flow through the bore and the first exhaust gas passageway. The valve shaft being supported for rotation by the trunnions.

  • Patent number: 11022069
    Abstract: An exhaust gas heat recovery system includes a housing assembly, a valve assembly and a heat exchanger. The valve assembly is disposed within the housing assembly and includes a shaft and a plate. The plate is rotatable between a first position whereat exhaust gas flow through a first fluid passageway is allowed and exhaust gas flow through a second exhaust gas passageway is prevented, and a second position whereat exhaust gas flow through the second fluid passageway is allowed and exhaust gas flow through the first gas passageway is prevented. The heat exchanger assembly includes a heater core having a working fluid circulating therein. The working fluid is in thermal communication with fluid in the heater core. The housing assembly includes first and second shells attached to each other at a joint. An axis of the shaft being at the joint of the first and second shells.

  • Patent number: 10344646
    Abstract: An exhaust gas burner assembly includes a body, an inlet opening, an outlet opening, a first chamber, a second chamber, and an intermediate opening. The exhaust gas burner assembly also includes a perforated pipe disposed between the first chamber and the second chamber, a fluid injector adapted to discharge a combustible mixture, and an igniter adapted to ignite the combustible mixture to generate combustion products. The perforated pipe allows at least a portion of the exhaust gas to flow therethrough from the first chamber to the second chamber such that the exhaust gas exiting the outlet opening has a higher temperature than the exhaust gas entering through the inlet opening.
