A variable speed V-belt transmission in which the axially movable pulley half has fixed to it a cap that defines an internal cavity in which the speed responsive mechanism is incorporated for axially moving this pulley half. The cap is formed with a plurality of apertures that pass a portion of the transmission when the axially movable pulley half is in one of its extreme positions for cooling the transmission.

In a V-belt automatic transmission comprising a shaft, a pair of spaced pulley halves one of which is axially affixed to said shaft and the other of which is axially movable relative to said shaft, said pulley halves being adapted to receive a V-belt therebetween, a cap fixed to one of said pulley halves on the side opposite the other of said pulley halves and defining with said one pulley half an internal cavity, a spider member rotatably coupled with said shaft and contained within said cavity, said spider member and said one pulley half being supported for axial movement relative to each other, and speed responsive means for effecting relative axial movement between said spider member and said one pulley half and for applying said relative axial movement into axial movement of the axially movable pulley half in response to the speed of said shaft, the improvement comprising said cap having at least one opening formed therein sized to pass a projecting portion of said spider member when said spider member and said one pulley half are in an extreme axial position for cooling of said transmission, said projecting portion being contained completely within the internal cavity when said spider and said one pulley half are in the opposite extreme axial position.
