| 摘要 |
The present invention relates to a hydraulic power transmission constituted by two groups of hydraulic motors by at least one source of pressurized fluid feeding the motors of the first group, while, concomitantly, the motors of the second group are driven by their shaft, and by a first speed limiter arranged on the delivery conduit of the first group of motors, wherein the motors of the second group having a "free wheel" function and being connected to ensure this function, a conduit connects the delivery of the first group of motors to the feed of the second group of motors and is connected upstream of the first speed limiter, while a second speed limiter is arranged downstream of the point of connection of the conduit, in the irrigation circuit of the motors of the second group.
