摘要： An internal combustion engine has an enclosure mounted therearound comprising an outer enclosure having a horizontally disposed hood positioned over a top of the engine and a pair of vertically disposed sidewalls positioned on either side thereof. An inner enclosure, disposed within the outer enclosure, comprises a horizontally disposed upper wall which is spaced vertically between the top of the engine and the hood to define first and second airflow passages therewith, the second airflow passage being further defined in part by the sidewalls. The inner enclosure further comprises a vertically disposed forward wall positioned adjacent to the front of the engine. An airflow guide means is secured internally on each of the sidewalls to define a passage therebetween which communicates with the second airflow passage defined about the engine. A first outlet means is defined rearwardly on each of the sidewalls to communicate airflow from the first airflow passage to ambient whereas a second outlet is defined at the bottom of the enclosure and beneath the engine for communicating the second airflow passage to ambient. The hood, sidewalls and upper and forward walls of the inner enclosure each have a layer of sound absorbing material secured thereon.

摘要： A wheel assembly comprises an axle housing secured to the frame of a vehicle, a spindle secured to the axle housing and a wheel rotatably mounted on the spindle. The axle housing and wheel spindle are secured together at radial flanges thereof by a plurality of circumferentially disposed bolts. A concavity is formed on the inner face of each of the flanges to impose compressive forces on radially inner portions thereof when the flanges are drawn and secured together by the bolts.
