Abstract: A transmission housing (1) which can be coupled to the drive shaft (21) of an electric motor (20) to form a gearbox (22), the transmission housing (1) comprising a housing body (2) defining a cavity (4), and housed at least partially inside the cavity (4)—a rotary drive member (5),—an output shaft (6) and,—a device (7) for transmitting the rotational movement of the rotary drive member (5) to the output shaft (6), characterised in that the rotary drive member (5) is supported inside the cavity (4) of the housing body (2) by one or more guide members (8) and comprises a wall (9) and two coaxial helical teeth (10) created from a single part with the wall (9) and arranged on either side of the wall (9), the helical teeth (10) being configured to generate axial forces in opposite directions.

Abstract: Gear box (1) comprising a gearbox body (2) defining a cavity (3) and, housed inside the cavity (3), an output shaft, and a braking device mounted on a rotating shaft (9), this braking device comprising two activatable brakes (61, 62), two stops (71, 72) mechanically coupled to one another and surrounding the brakes (61, 62), and a control member (8) for moving the brakes (61, 62), common to the two brakes (61, 62), and mounted to move between an inactive braking position and an active braking position, at least one of the stops (71, 72) forming an end-of-travel stop limiting the movement of the brakes (61, 62) in the active braking position of the control member (8).

Abstract: The invention relates to a transmission device (1) comprising a housing (2), two electric motors (3) arranged outside the housing (2) and each provided with a motor shaft (4) projecting at least partially into the housing (2), an output shaft (5) formed by at least two shaft sections (51, 52) which are coaxial and mounted freely rotatable relative to one another, a motion transmission mechanism (6) configured to transmit the rotational motion of one of the motor shafts (4) to one of the shaft sections (51, 52) of the output shaft (5) and the rotational motion of the other of the motor shafts (4) to the other of the shaft sections (51, 52) of the output shaft (5), the transmission mechanism (6) and the output shaft (5) being housed at least partially within the housing (2).

Abstract: A transmission housing (1) comprising a shaft (2) housed at least partially inside the housing (1) and, mounted on said shaft (2), at least one rotary element (3) and a rolling bearing (4), the rolling bearing (4) comprising an inner ring (5) and an outer ring (6) that are coaxial, separated from each other by rolling members (7). The housing (1) further comprises a blind or through tubular body (8) mounted on the shaft (2) and interposed at least partially between the shaft (2) and the rotary element (3), the rotary element (3) being mounted rotatably secured to the tubular body (8), and the tubular body (8) being kept rotatably secured to the shaft (2) by the inner ring (5), referred to as the constriction ring, of the rolling bearing (4), force-fitted onto said tubular body (8).

Abstract: A transmission assembly for a self-propelled machine includes a transmission housing fitted with an input shaft and an output shaft, a so-called drive shaft linked to the input shaft by an endless belt transmission and, arranged between the drive shaft and the output shaft, transmission elements including a control mechanism for reversing the rotational drive direction of the output shaft, and a clutch control mechanism, the direction reversing and clutch controls carried by the housing being mounted respectively movable, one between at least three positions: a neutral position, a forward position and a reverse position, the other between at least an engaged position and a disengaged position. The direction reversing control forms, in the neutral position, an element for blocking the clutch control in the disengaged position, and the clutch control forms, in the engaged position, an element for locking the direction reversing control in the forward or reverse position.
