The transmission ratio change unit having permanent stepped meshing and perpetual power transmission having the changeable variable speed gear in an unstable operation mode characterised by, having an element, preferably with the taper outline, wherein on the outer surface of the element there is the spiral outline of the gear ring (1) placed on the intermediate motion shaft (2) rotating along the circumference of the clutch shaft (3) and it has the gear-box shaft (4) with sliding gear wheel (5) which is meshed with the gear ring (1) having the spiral outline and the lower gear-box shaft (6) has the sliding gear wheel (7) meshed with gear ring (1) having the spiral outline wherein gear wheel (5) slides towards the gear wheel (7) and the gear wheel (7) slides towards the gear wheel (5). The transmission ratio change unit having permanent stepped meshing and perpetual power transmission having a clutch integrated with the multistage mechanical transmission unit with permanent meshing in the stable operation mode, wherein the mechanical gear has two parallel shafts; the driving shaft and the driven shaft, where the driven shaft or the driving shaft forms the monolithic unity with the gears having different number of teeth and is independently mounted on bearings in the gearbox housing and is permanently meshed with the driving gears or the driven gears, characterised by having slidingly displaced clutch (7) placed inside or outside the driven gears (4) where the clutch is displaced along the driven multispline shaft (8) transferring the turning moment via the frictional surfaces (5, 6) which are perpendicular to the longitudinal axis of the shafts (1, 2) of the gear box and inside or outside driving wheels (14) there is placed sliding clutch (17) moving along the driving multispline shaft (18) transferring the turning momemt via the frictional surfaces (15, 16) pependicular to the longitudinal axis of the shafts (11, 12) of the gear box. The transmission ratio change unit having permanent stepped meshing and perpetual power transmission having the clutch with the frictional working surface (5, 6, 15, 16) transferring the turning moment and forming a side surface with any outline preferably with the cylindrical outline. |
