  • Publication number: 20080142290
    Abstract: A vehicle drive system including: a front drive unit in a front part of a vehicle, which has an engine and a torque converter integrally assembled to one another; a rear drive unit in a rear part of the vehicle, which has a transmission and a differential integrally assembled to one another; and a drive shaft connecting the torque converter of the front drive unit and the transmission of the rear drive unit. The drive shaft is configured to be elastically twistable for damping vibration transmission between the front and rear drive units.

  • Patent number: 6435298
    Abstract: A rear underside structure of a vehicle as a rear undercover main body, an air flow path, an air intake opening, and an air exhaust opening. The rear undercover main body has an inclined planar part that rises toward the rear of the vehicle, and is disposed further to the rear of than the fuel tank, between the front and rear axles, so as to cover a drive element of the vehicle. The air flow path is disposed between the rear undercover main body and the drive element. The inclined planar part delineates at least a rear part of the air flow path. The air intake opening is disposed further to the front than the drive element, and the air exhaust opening is disposed to the rear of the inclined planar part. Air which flows in from the air intake opening passes through the air flow path, and is exhausted from the exhaust opening.

  • Patent number: 4424986
    Abstract: Side members which extend along each side of an engine compartment are designed and arranged so that they will buckle out sideways during a frontal collision to absorb initial impact energy. This prevents the engine from being pulled upwardly in the vehicle and allows same to be driven rearwardly to stagewisely crush structual panels to absorb further impact energy. The movement of the engine directly rearwardly also allows for the cross member/side sill chassis construction to receive and dissipate the energy not absorbed through panel deformation. Accordingly, the forward bulkhead is not directly deformed by the engine which would otherwise occur if the engine were forced upwardly by the impact.
