A transmission for vehicles with hybrid propulsion systems. In particular agricultural or industrial vehicles, wherein the propulsion system comprises a motor of the non-regenerative type, a motor of the regenerative type which is associated with an energy accumulator and with a generator. The transmission includes an input shaft which is connected to the motor of the non-regenerative type and to which the generator is connected, a low-speed shaft and a high-speed shaft which can be selectively coupled to the input shaft by respective clutches, a movement combination device, an output shaft which is connected to the movement combination mechanism, and a blocking element which is configured to block the low-speed shaft or the high-speed shaft.

Transmission for agricultural and industrial vehicles

A gearbox () for agricultural and industrial motor vehicles comprises an input shaft () and an output shaft (), a first clutch () and a second clutch () arranged in a position between the first and second transmission shafts (), the first and second transmission shafts both being hollow. The gearbox further comprises a first intermediate shaft () and a second intermediate shaft (), the first intermediate shaft extending coaxially inside the second intermediate shaft. A first engaging device () is capable of selectively connecting the first intermediate shaft to the output shaft, a second engaging device () is capable of selectively connecting the second intermediate shaft to the output shaft and a third engaging device () alternately connects the second intermediate shaft to the first intermediate shaft or to the output shaft. The first engaging device and second engaging device are coaxial with the output shaft. The third engaging device is coaxial with the first and second intermediate shafts and is interposed in an axial position between the first and second engaging devices.

Gearbox for agricultural and industrial vehicles

A hydraulic circuit for the transmissions of industrial and agricultural vehicles. The circuit comprises a feed pump driven by an internal combustion engine; a lubricating circuit; a main pressure regulator capable of bringing about a first change in the pressure of the working fluid in the circuit, this change in pressure being capable of regulation in relation to a first regulation pressure; a maximum pressure regulator for the lubrication circuit capable of bringing about a second change in pressure of the working fluid depending upon a second regulating pressure; and means for regulating regulation of the first and second regulating pressures.
