Abstract
A bi-directional torque transmission unit (1) comprises an input shaft (2) connectable to a prime mover and provided with an input drive gear wheel (3), first and second driven shafts (4, 4A) each having a driven gear (5, 5A) constantly in mesh with the input drive gear wheel (3), so that they are rotatable in the same direction, a hydraulically actuated and modulated clutch (7, 7A) interconnecting each driven shaft (4) with an intermediate, output shaft (6, 6A) and a final, output shaft (11) connectable to a load, and both the first and the second output shafts (6, 6A) having an output gear (12, 12A) whereby selective or simultaneous engagement of one or other of the modulated clutches (7, 7A) transmits torque to the final output shaft (11).
Claims11
A bi-directional torque transmission unit comprising an input shaft connectable to a prime mover, an input drive gear wheel provided on said input shaft, first and second driven shafts, a driven gear wheel provided on said first and second driven shafts, said driven gear wheels being in mesh with said input drive gear wheel, such that said first and second driven shafts are rotatable only in the same direction;
- first and second intermediate output shafts, geared together and, in their respective drive modes, rotatable in the same direction;
- first and second hydraulically actuated and modulated clutches interconnecting said first and second driven shafts, respectively, with said first and second intermediate output shafts, with said clutches engageable selectively;
- and a final output shaft in drivable relationship with both said first and second intermediate output shafts, whichever clutch is selected for engagement determining the direction of rotation of said final output shaft, and said first and second modulated clutches being sequentially engageable for simultaneous engagement to provide regenerative retarding of the rotation of said final output shaft in either of said directions.
