#CMT# #/CMT# The unit has a belt transmission (9) between two pulleys (1, 11), where each pulley including variably-spaced flanges (4, 5) is mounted on a shaft (2). One flange is equipped with a loading device that tends to permanently exert an axial effort in a direction in which the flanges move toward one pulley to clamp the belt transmission between the flanges. One of the pulleys has a manual control element (19) that draws together or separates the flanges that are able to exert a slight control effort essentially corresponding to a difference in power of loading devices on the flanges. #CMT#USE : #/CMT# Used for variable-speed drive device e.g. riding mower and lawnmower (claimed), and for a vehicle. #CMT#ADVANTAGE : #/CMT# The manual control element draws together or separates the flanges that are able to exert the slight control effort essentially corresponding to the difference in power of the loading devices on the flanges, thus reducing the control effort to be produced by an operator with the ensured speed variation, and hence facilitating the driving of the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cutaway view of a variable-speed drive unit. 1, 11 : Pulleys 2, 12 : Shafts 3, 13 : Opposite parts(4, 5, 14, 15) Flanges 6, 16 : Springs 9 : Belt transmission 19 : Manual control element 20 : Rolling element. |
