The invention relates to a fluid driven transmission means comprising a fluid pressure source (1) and a motor (5, 5a) connected thereto for rotating a secondary shaft (9). The invention also relates to a process for the realization and control of a transmission and further to a trailer (32) connectable to a tractor (36) and having wheel boggies (34). According to the invention the differences in pressures and counter pressures depending on and/or indicating stress and/or rotation of the motor (5, 5a) are detected in fluid conduit means (6, 7) extending between the pressure source (1) and the motor (5, 5a) and a detected pressure difference is used for connecting and disconnecting a secondary shaft (9) to and from the motor (5, 5a). Means (13, 14, 15) for controlling the clutching function are connected to conduit means (3, 6, 7) extending between the pressure source (1) and a gearing unit (5-12). The clutching functions are controlled in such a way that secondary shaft means (9) are disconnected and move freely and independently from the gearing (12), or are in a torsion transmissive connection with the motor (5, 5a). The trailer (32) comprises a transmission/clutching arrangement and further means (33) for adjusting the angle of the boggie (34) with respect to the body (35) of the trailer (32). |
