TH100386A - Cooling construction for a continuously variable power transmission, belt type. - Google Patents

Abstract

DC60 to provide a cooling structure for a highly variable power transmission unit. Continuous belt type With a small number of parts to work with and are easily and easily built Compact to offer a distinctive appearance At the same time, it can prevent the entry of water, dust, and powder. A cooling structure is provided for the variable transmission. The belt-type 46 is assembled in a 20 power pack that is mounted on the motorcycle. The 20 power pack contains a 46C transmission cavity that has been formed by 36 driver unit enclosures placed on top. 31L drive cab from one side to continuously cover the variable transmission belt type; The 48F cooling fan has been placed on the tip of the crankshaft 40; 36i cooling air inlet molded into 36i driver unit cladding at position opposite to 48F cooling fan 36i cooling air inlet for air intake for cooling Into the cavity of the 46C transmission unit; And side hood assembly 92 for side hood cover, air inlet for cooling 36i in driver hood 36 and the same enclosing area in this 20 power unit, side muffler 92. A top-exit 95 external air inlet is provided at part of the Cover assembly pieces Where the end face of the perimeter of the side cover assembly 92 will be matched with the driver unit 36 to provide a cooling structure for the variable power transmission unit.
