Abstract: A transfer case for use with four-wheel drive vehicles incorporates a pass-through power takeoff shaft to drive remote secondary implements or accessory devices. The power takeoff shaft delivers rotational power from the vehicle transmission to the remote implement or accessory by passing through the housing of the transfer case to improve ground clearance and minimize driveline angles. The housing for the transfer case can mount bearings that rotatably support the power takeoff shaft. Alternatively, a tubular member can be mounted in the transfer case to provide a passageway through which the power takeoff shaft can pass through the transfer case. The points of engagement of the power takeoff shaft and the transfer case housing are sealed to prevent the loss of lubricating fluid from the transfer case. In each embodiment, the power takeoff shaft passes through the transfer case without engagement of or interference with the drive components therein.

Abstract translation: 用于四轮驱动车辆的分动箱包括一个直通动力输出轴，以驱动远程二次工具或附件装置。 动力输出轴通过穿过转移箱的壳体将车辆变速器的旋转动力传递到远程工具或附件，以提高离地间隙并最小化传动系统的角度。 用于转移箱的壳体可以安装可旋转地支撑动力输出轴的轴承。 或者，管状构件可以安装在转移箱中以提供通道，动力输出轴可以通过该通道通过转移箱。 动力输出轴和分动箱壳体的接合点被密封以防止来自转移壳体的润滑流体的损失。 在每个实施例中，动力输出轴穿过转移壳体而不与其中的驱动部件接合或干涉。
