Claim:
A continuously variable transmission ( 1 ; 31 ) to transfer a relative rotary motion between at least one first driven rotary part ( 2 ; 32 ) and a housing on at least a second driving rotary part ( 3 ; 33 ), the transmission comprising: a) the first driven rotary part ( 2 ; 32 ) or the housing being coupled with a first guide module ( 5 , 5 ′; 35 ); b) a second guide module ( 14 ) being provided; c) the two guide modules ( 5 , 5 ′, 14 ; 35 ) being connected with the housing of the transmission ( 1 ; 31 ) or with an adjacent part rotatably or swivelably mounted thereon, such that the second guide module ( 14 ) can be displaced with respect to the first guide module ( 5 , 5 ′; 35 ); d) the two guide modules ( 5 , 5 ′, 14 ; 35 ) being coupled with one another by means of at least two coupling mechanisms, each consisting of a first coupling module ( 7 a - 7 d ) and a second coupling module ( 8 a - 8 d ), which are mounted on one another or mesh with one another; e) the first coupling module ( 7 a - 7 d ) of each coupling mechanism being coupled with the first guide module ( 5 , 5 ′; 35 ), such that the first coupling module is rotatable around one of several rotational axes (M 1 ,M 2 ,M 3 ,M 4 ) which are parallel to its rotational straight line but excentric or fixed to one of several fastening points which are excentric to its rotational straight line; f) the second coupling module ( 8 a - 8 d ) of each coupling mechanism is coupled with the second guide module ( 14 ), independent of the second coupling modules ( 8 a - 8 d ) of the remaining coupling mechanisms, mounted such that it can rotate around an axis common to all connected second coupling modules ( 8 a - 8 d ), the common axis not revolving excentrically during operation; g) and the first coupling module ( 7 a - 7 d ) of each coupling mechanism being mounted on a rotational axis (M 1 , M 2 , M 3 , M 4 ), whose distance from the point of rotation with the associated second coupling module ( 8 a - 8 d ) exhibits a specified radius (d 1 -d 4 ); h) the first or second coupling module ( 7 a - 7 d ; 8 a - 8 d ) of each coupling mechanism being coupled with at least a first rotary connection of a freewheel ( 16 a - 16 d ), whose other rotary connection is coupled with a third rotary part ( 18 ), such that a transport movement of the deflection angle of the rotary movement of the relevant first or second coupling module ( 7 a - 7 d , 8 a - 8 d ) is cyclically transferred to the third rotary part ( 18 ), and the rotary axes of the rotary connections of the freewheel ( 16 a - 16 d ) being aligned with one another; i) and the third rotary part ( 18 ) and the first driven and second driving rotary parts ( 2 , 3 ; 32 , 33 ) being coupled each to different connections ( 19 , 23 , 25 ) of a differential transmission module ( 20 ).
