A cooler for a belt type stageless transmission in a vehicle in which a transmission casing is provided on one side of an engine body, and a belt type stageless transmission for operatively connecting between a crank shaft of the engine body and an output shaft supported in the transmission casing is housed in the transmitted casing, wherein a centrifugal fan for sucking the open air into the transmission casing is provided on either one of a pair of pulley halves of a variable diameter pulley of the transmission and an axial flow fan for guiding the sucked-in open air in the axial direction of the variable diameter pulley is provided on the other pulley half; wherein an air intake port is opened in the front portion of the transmission casing in the vicinity of the centrifugal fan and an air exhaust port is in the rear portion of the transmission casing, and a guide plate for guding the air flowing along the lower surface of the transmission casing so as to peel it off from the lower surface is further provided on the rear portion of the transmission casing below the air exhaust port; and further wherein an air passage through which the running air can flow is defined between the engine body and the transmission casing.
A cooler for a belt type stageless transmission in a vehicle in which a transmission casing is provided on one side of an engine body, and a belt type stageless transmission for operatively connecting a crank shaft of said engine body and an output shaft supported in said transmission casing is housed in said transmission casing, wherein a centrifugal fan for sucking open air into said transmission casing is provided on either one of a pair of pulley halves of a variable diameter pulley of said transmission, and an axial flow fan for guiding the air drawn in by said centrifugal fan in an axial direction of said variable diameter pulley is provided on the other pulley half.
A cooler for a belt type stageless transmission in a vehicle in which a transmission casing is provided on one side of a engine body, and a belt type stageless transmission for operatively connecting a crank shaft of said engine body and an output shaft supported in said transmission casing is housed in said transmission casing, wherein an air intake port is provided in a front portion of said transmission casing and an air exhaust port is provided in a rear portion thereof, and an exterior guide plate for guiding air flowing along a lower surface of said transmission casing so as to peel the air flow off from said lower surface is provided on the rear portion of said transmission casing below and spaced from said air exhaust port.
A cooler for a belt type stageless transmission in a vehicle in which a transmission casing is provided on one side of an engine body, and a belt type stageless transmission for operatively connecting a crankshaft of said engine body and an output shaft supported in said transmission casing is housed in said transmission casing, wherein an air induction passage through which running air flows is defined between said engine body and said transmission casing, and said transmission casing has an air intake port in a front portion thereof and an exhaust port in a rear portion thereof for guiding outside air through the air intake port into an interior of said casing and allowing the induced air to be discharged outside from the air exhaust port, and wherein said air induction passage is separated from the interior of the transmission casing connecting the air intake and exhaust ports.
