Abstract (en)

[origin: WO2009076999A1] The invention relates to a continuously variable transmission comprising two pulleys, each defining an effectively V-shaped circumference groove of variable width, a drive belt that is wrapped around the pulleys and that comprises a large number of case hardened steel transverse elements provided on an endless tensile means of the belt, and a cooling device for cooling the belt during operation of the transmission by supplying a cooling agent to the belt in a re-circulating manner. According to the invention the transmission does not comprise a component for enhancing, or otherwise specifically aimed at, the cooling of the cooling agent itself.
