Abstract: A continuously variable transmission housing including an inner cover and an outer cover that define an interior chamber that is structured and operable to enclose a continuously variable transmission primary pulley, secondary pulley and pulley belt. The housing includes a duct panel mounted to the inner cover such that when the primary pulley is disposed within the interior chamber, the duct panel is disposed between an outer face of the primary pulley and the inner cover. An air duct is defined between the inner cover and the duct panel, wherein the air duct is fluidly connected to ambient air from an ambient environment external to the housing. The duct panel forms at least a portion of an ambient air inlet of the housing and includes a center opening that structured and operable to allow the ambient air to be drawn through the air duct and into the housing interior chamber.

Abstract: An off-highway recreational vehicle includes side-by-side passenger and driver seats held within a chassis. The seats sit low in the chassis and are covered by a roll-over protection system (ROPS). The vehicle is powered by an engine rearward of the seats that utilizes a continuously variable transmission (CVT) to provide power to the ground engaging members, wherein the CVT is cooled via air captured by a CVT intake body located adjacent the driver-side seat, between the frame and external panels of the utility vehicle.
