    PRIOR ART
    In general, when a rolling machine is equipped with a transmission for rotating at least one pair of wheels of the machine with each wheel driven independently of the other, the assembly is in accordance with Figure 1 which represents the state of the art. Thus, the drive shaft of the wheels, also called output shaft of the transmission, is formed of two half-shafts each housed at least partially in a housing. Each housing houses a motor with a motor shaft meshing directly with the drive output half-shaft of a wheel of the machine. In such an assembly, under the effect of the weight of the chassis of the machine, there is a significant risk of misalignment of the output half-shafts as shown in Figure 1. This misalignment can have adverse consequences for driving the vehicle. gear.

    DETAILED DESCRIPTION
    As mentioned above, the transmission 1, which is the subject of the invention, is more particularly intended to enable the moving workout of a rolling machine, such as a plow, a mowing tractor, a golf cart or others.
    This transmission 1 comprises a housing 2 delimiting an enclosure. This housing 2, preferably of synthetic material, is formed of two half-shells assembled by a joint plane. This housing 2 is generally filled with a lubricant. Inside this housing, partially fits the output shaft of the transmission, which here forms the drive shaft of the wheels of a pair of wheels of the machine. This output shaft is formed of a first output shaft section 31 and a second output shaft section 32 interconnected freely relative to one another by at least one a connecting piece 6 disposed inside the casing 2.
    This connecting piece 6 between output shaft sections 31, 32 has the shape of a sleeve, preferably of metal, inside which the end of each output shaft section faces the other section. output shaft, is nested. The end of each shaft section opposite to that fitted to the connecting piece 6 protrudes from the housing and is equipped with a drive wheel in movement of the machine. Thus, the force generated by the frame of the machine does not cause a deflection of the output shaft and limits the risk of deformation of the housing.
    The transmission 1 further comprises a first motor 41 and a second motor 42. These motors 41 and 42 are arranged outside the housing. In the example shown, the first motor 41 and the second motor 42 are carried by the housing 2 and the first and second motors 41, 42 are electric motors with reversing direction and variable speed. These first and second motors have a maximum rotational speed of at least 10,000 rpm.
    Thanks to the design of the rest of the transmission, these motors are small motors, that is to say at relatively high speed of rotation and low torque so that the cost is reduced. It should be noted that, alternatively, the motors could have been housed outside the housing, but remotely with respect to said housing.
    These first and second motors are each equipped with a motor shaft whose rotational movement is adapted to be transmitted to an input shaft of the transmission. Thus, the drive shaft of the first motor 41 is able to transmit, its rotational movement to the first input shaft 51 of the transmission, while the drive shaft of the second motor 42 is able to transmit its rotational movement to the second input shaft 52 of the transmission. These first and second input shafts extend parallel to the output shaft.
    In the example shown, to allow such a transmission of movement, the drive shaft of each motor 41, 42 is equipped with an epicyclic gear train 15, 16 known per se, and which will not be described in detail.
    The output of this planetary gear train is coupled, via an endless transmission, in this case a chain transmission, to the input shaft. Thus, the drive shaft of the first motor 41 is able to transmit, via the epicyclic gear train 15 and an endless transmission 191, its rotational movement to the first input shaft 51, while the drive shaft of the second motor 42 is able to transmit, via the epicyclic gear train 16 and an endless transmission 192, its rotational movement to the second input shaft 52. In the example shown, the first and second input shafts are housed at least partially in the inside the case 2.
    The transmission further comprises two intermediate shafts 101 and 102, extending inside the housing, parallel to the first and second input shafts 51, 52. Thus, the rotational movement of the first input shaft 51 is suitable for be transmitted to the intermediate shaft 101, while the rotational movement of the second input shaft 52 is adapted to be transmitted to the intermediate shaft 102. These intermediate shafts 101, 102 also extend parallel to the first and second sections 31, 32 output shaft. Each intermediate shaft transmits its rotational movement to the associated output shaft section via a gear.
    To allow such a transmission of movement between the input shaft and the intermediate shaft, there is provided a clutch mechanism carried either by the input shaft or by the intermediate shaft, and at least one gear train. comprising at least two gear meshes meshingly and mounted, one on the input shaft, the other on the intermediate shaft.
    In the example shown in Figure 3, the clutch mechanisms are carried by the intermediate shafts, while in the example shown in Figure 4, the clutch mechanisms are carried by the input shafts.
    Thus, in the example shown in Figure 4, a first clutch mechanism shown at 71 is carried by the first input shaft 51, while a second clutch mechanism shown at 72 is carried by the second shaft 52.
    In the example shown in Figure 3, a first clutch mechanism shown at 71 is carried by the intermediate shaft 101, while a second clutch mechanism shown at 72 is carried by the other intermediate shaft 102.
    In the examples shown, there are provided two gear trains shown at 13 and 14 in the figures, between each input shaft and the associated intermediate shaft. These gear trains have a reduction ratio different from one gear to another gear. Each gear train comprises, as mentioned above, at least two gear meshing meshes and mounted, one on the input shaft, the other on the intermediate shaft.
    In the example shown in FIG. 3, the gears of the gear trains mounted on the first and second input shafts are mounted integral in rotation with the said first and second input shafts, whereas the gear wheels of the trains mounted on the intermediate shafts 101, 102 are rotatably mounted on said shafts, each carrying a clutch mechanism to enable transmission of the movement of the input shaft to the intermediate shaft in the engaged state of the clutch mechanism .
    In the example shown in FIG. 4, the gears of the gear trains mounted on the first and second input shafts are rotatably mounted on the first and second input shafts, whereas the gear wheels of the trains mounted on the intermediate shafts 101, 102 are mounted integral in rotation with said shafts. The first and second input shafts each carry a clutch mechanism to enable the movement of the input shaft to be transmitted to the clutch engagement gear shaft.
    In the examples shown, the first and second clutch mechanisms 71, 72 are identical and each form a clutch mechanism by interconnection. Each clutch mechanism by interconnection comprises two jaws 18, 19 said fixed mounted axially fixed and free to rotate on the shaft 51, 101; 52, 102 carrying the clutch mechanism 71,72 and, interposed between said jaws 18, 19 fixed, a clutch 17 movable mounted on the shaft 51, 101; 52, 102 carrying said clutch mechanism 71, 72, integral in rotation and axially displaceable via the clutch control member 81, 82 of said clutch mechanism 71, 72 for a displacement of said clutch 17 movable between a disengaged position spaced apart from said jaws 18, 19 fixed, a first engaged position engaged with one 18 of the fixed jaw and a second engaged position engaged with the other 19 fixed jaw.
    The mobile clutch is in the form of a wheel slipped on the shaft that carries it. This wheel is integral in rotation with the shaft which carries it, by pinning or by means of splines or others. This wheel is provided on each of its faces with so-called axial dog teeth.
    Each fixed clutch is formed by a pinion threaded onto the shaft which carries it and rotatably mounted on said shaft, but fixed axially on said shaft. Each fixed clutch is equipped on its face facing the movable clutch, axial clutch teeth which interpenetrate with the clutch of the dog teeth clutch engaged clutch mechanism.
    To allow the passage of the disengaged position to one of the engaged positions, the operator, namely here the driver of the machine, actuates the clutch control member. In the examples shown, the clutch control members 81, 82 of the first and second clutch mechanisms 71, 72 affect the form of pivoting levers protruding from the same face of the housing 2. In particular, each control member clutch is formed of a fork with two branches. Each branch is provided with an internal radial tooth which fits into an outer peripheral annular groove of the mobile clutch. This fork is angularly displaceable and causes, during its angular displacement, an axial displacement of the movable clutch.
    Each fixed dog forms one of the pinions of the gear train mentioned above and which extends between the input shaft and the intermediate shaft. This pinion engages meshing with a second pinion carried by the intermediate shaft or input, which does not carry the clutch mechanism. In this case, in Figure 3, the input shaft. Thus, in the example shown in FIG. 3, the movement transmission between the input shaft and the intermediate shaft can take place as described below. This description can be made on the first input shaft, knowing that it applies similarly to the second input shaft.
    The first input shaft thus carries two pinions mounted integral in rotation with the shaft and each engaged by meshing with a fixed clutch 18, 19 of the first clutch mechanism 71 carried by the intermediate shaft 101. In the disengaged position of the first clutch mechanism 71, the rotational movement of the first input shaft is transmitted to the fixed jaws mounted free to rotate on the intermediate shaft 101. The intermediate shaft 101 is not rotated. In the first engaged position of the first clutch mechanism, the mobile clutch 17 engages, for example, with the fixed clutch 18. As a result, the rotational movement of the first input shaft is transmitted via the train 14. gearing including the fixed claw 18 and via the movable clutch, to the intermediate shaft 101 which itself engages via meshing with the first output shaft section 31 for rotational drive of the first output shaft section 31 at a speed depending on the reduction ratio of the gear train including the fixed clutch 18. In the second engaged position of the first clutch mechanism, the mobile clutch 17 engages, for example with the fixed dog 19. As a result, the rotational movement of the first input shaft is transmitted via the gear train 13 including the fixed dog 19 and via the mobile dog to the shaft 101. intermediate , which itself meshingly engages a gear with the first output shaft section 31 for rotational drive of the first output shaft section 31 at a speed dependent on the gear reduction ratio of the gear. gears including fixed clutch 19.
    The gear trains 13, 14 having different gear ratios, the first output shaft section 31 can be driven at different rotational speeds depending on the selected gear train. It should be noted that in the disengaged position of the clutch mechanism, the first output shaft section is free to rotate in one or other of its directions of rotation, which corresponds to the freewheeling of the gear wheel associated with the first output shaft section.
    The rotational speed of the first output shaft section can be further varied by varying the rotational speed of the motor shaft of the first motor. Similarly, the direction of rotation can be reversed, depending on the direction of rotation of the first motor.
    As mentioned above, the operation of the second transmission assembly 112 formed of the second motor 42, the second input shaft 52, the second clutch mechanism 72 carried by the second input shaft 52 or an intermediate shaft 102 mounted rotatably connected to the second input shaft 52, the second output shaft section 32 and the gearbox 92 disposed at least partially between the second motor 42 and the second output shaft section 32 is similar to that of the first set 111 of transmission formed of the first motor 41, the first input shaft 51, the first clutch mechanism 71 carried by the first input shaft 51 or an intermediate shaft 101 to which the rotational movement of the first input shaft is able to be transmitted, the first output shaft section 31 and the gearbox 91 disposed at least partially between the first motor 41 and the first shaft section 31 of the output shaft 31. tie, as described above.
    Figure 4 differs from Figure 3 only in that the clutch mechanisms are carried by the input shafts. Thus, the motion transmission between the input shaft and the intermediate shaft can take place as described below. This description will be made for the first input shaft, knowing that it applies similarly to the second input shaft.
    The first input shaft thus carries the fixed jaws 18, 19 and the clutch 17 mobile first clutch mechanism 71. The fixed jaws 18, 19 each mesh with a pinion carried by the intermediate shaft 101 and rotatably mounted to said intermediate shaft. It should be noted that the same numerical references were used for similar parts.
    In the disengaged position of the first clutch mechanism, the rotational movement of the first input shaft is not transmitted to the intermediate shaft. It should be noted that the rotational movement of the intermediate shaft can be transmitted to the first output shaft section via a gear between the intermediate shaft and the first output shaft section. In the first engaged position of the first clutch mechanism, the movable clutch engages the fixed clutch 18 and the rotational movement of the first input shaft is transmitted via the movable clutch to the fixed clutch 18 which itself transmits its rotational movement to the intermediate shaft 101 by meshing with a pinion carried integrally in rotation on the intermediate shaft 101. This rotational movement of the intermediate shaft 101 is then transmitted via a gear, to the first section of output shaft.
    In the second engaged position of the first clutch mechanism, the movable clutch engages the fixed clutch 19, and the rotational movement of the movable clutch of the first input shaft is transmitted to the fixed clutch 19 which itself transmits its rotational movement to the intermediate shaft 101 by meshing with a pinion carried by and mounted integral in rotation with the intermediate shaft 101. This rotational movement of the intermediate shaft 101 is then transmitted via a gear which may be common to that used in first engaged position at the first output shaft section. Again, the rotational speed of the countershaft is a function of the reduction ratio of the gear train between input shaft and intermediate shaft.
    The operation of the second transmission assembly formed of the second motor, the second input shaft, the second clutch mechanism carried by the second input shaft or an intermediate shaft to which the rotational movement of the second input shaft is fit. to be transmitted, the second output shaft section and the gearbox disposed at least partially between the second motor and the second output shaft section is similar to that of the first transmission assembly formed of the first motor, the first drive shaft, and the first drive shaft. input, of the first clutch mechanism carried by the first input shaft or an intermediate shaft to which the rotational movement of the first input shaft is transferable, the first output shaft section and the gearbox disposed at least partially between the first motor and the first output shaft section, as described above.
    Note that, in the embodiments described above, the gearbox disposed between the first motor and the first output shaft section and the gearbox disposed between the second motor and the second output shaft section comprise, level of the portion of the gearbox disposed between the input shaft and an intermediate shaft to which the movement of the input shaft is adapted to be transmitted at least one, here two gear trains, each gear train being formed of at least two pinions, one of which is carried by the input shaft and the other or another by the output shaft, one of the pinions forming the fixed clutch mechanism clutch.
    Of course, a combination of the two embodiments described above can also be envisaged, with for example a first transmission assembly according to Figure 3 and a second transmission assembly according to Figure 4, housed in the same housing.
    It may also be envisaged, in a variant, and in a manner not shown, to replace the two gear trains arranged between the input shaft and the intermediate shaft of each transmission assembly by a single gear train. . In this case, the clutch mechanism of the transmission assembly has a disengaged position and an engaged position, and the output shaft section of said transmission assembly is rotatably mounted in the disengaged position of the clutch mechanism and engaged with the input shaft of said transmission assembly via the gear train, in the engaged position of the clutch mechanism.
    For the control of the clutch mechanism by the operator, in this case the driver of the machine, it can operate in different ways. In the example shown, the clutch control member 81 of the first clutch mechanism 71 is mounted integral in displacement with the clutch control member 82 of the second clutch mechanism 72. clutch control can be independent on the move, without departing from the scope of the invention.
    It is thus possible to obtain for each selection of the output shaft, a direction of rotation and / or a speed different from the other section of the output shaft thus offering a large number of control possibilities and consequently maneuvering the craft.
