Embodiment Construction
[0020] first reference figure 1 , a transmission system according to the invention is indicated generally at 100 .
[0021] The transmission system 100 includes a torque converter 1 of known type, which is connected in the region of the input 11 to a drive shaft, not shown in the figure. drive shaft from e.g. figure 2 An irreversible endothermic engine M of the internal combustion type shown schematically in , receives a rotary motion.
[0022] still refer to figure 1 , the torque converter comprises a frame, which is shown in the figure only in a schematic manner and defines an annular chamber in which a centrifugal pump P is accommodated, which also acts on the converter 1 itself In this way the operating fluid present in the system is fixedly connected to the input 11 as well as to the drive shaft.
[0023] The converter 1 also comprises a turbine T, to which the operating fluid generates energy in order to rotate an output 12 of the converter fixedly connected to the ...

A transmission system for hybrid propulsion vehicles comprises a torque convertor, an external output shaft of the torque convertor which is rigidly connected to the output of the convertor and an internal output shaft which is rigidly connected to the input of the convertor, a gearbox which can be selectively connected to drive wheels of the vehicle, a main coupling member for selectively transmitting the movement of the external shaft to the gearbox, an electric motor which can be selectively operated as a motor and as anelectrical generator. The transmission system further comprises a downstream coupling member and an upstream coupling member which are arranged upstream and downstream of the torque convertor, respectively, and which are capable of selectively connecting the rotor element to the external shaft and the internal shaft, respectively. The electric motor further comprises a rotor element which is arranged at an opposite distal end of the external shaft with respect to thetorque convertor, with the main coupling member being arranged in an intermediate position between the torque convertor and the distal end.
Description
technical field [0001] The invention relates to a transmission system for hybrid traction vehicles, in particular vehicles of the industrial and agricultural type, of the type comprising a torque converter and an electric motor which can be selectively activated as an engine and as a generator. Background technique [0002] Recently, in the field of industrial and agricultural vehicles, the use of hybrid propulsion systems, in which an irreversible endothermic engine, usually an internal combustion engine, is combined with an electric type that can operate as both an engine and a generator has also become common. associated with reversible motors. [0003] Typically, industrial vehicles use a torque converter actuated by an endothermic engine that transmits motion to the vehicle through a gearbox. More specifically, the endothermic engine is connected to the pump of the torque converter while the transmission portion associated with the vehicle is connected to the turbine. ...
