    [0001] The present invention relates to the internal control of the speeds in a gearbox with assistance to the passage. More specifically, it relates to an internal gearbox control device comprising a rotary inter-locking key adapted to select one of at least two speed lines by simultaneously locking the unselected lines, and an axis of internal control immobilized in rotation with respect to the casing of the box and driven in axial translation under the control of an external passage control member to engage speeds on a selected gear line by moving a fork axis towards a committed gear position. This invention finds a preferred application, but not limited to, gearboxes comprising 20 hub / sliding assemblies which realize the interconnection of the pinions on their shaft (for example with jaw claws with square front or not), without means of mechanical synchronization but where the speed equalization of the gears and gear shafts prior to their coupling, can be entrusted to electrical machines and thermal engines. By the publication FR 2 988 800, there is known a device for assisting dog clutching, wherein a propellant device, consisting mainly of a spring, is interposed between a fork secured to its axis, and a dog clutch. Such a device can be used in several copies in gearboxes comprising at least two devices "fork assisted", each driving a group Walkman / clusters, under the control of an actuator. However, the increase in the number of parts of the box dedicated to the passage aid, has a negative impact on the total mass of it and on its - 2 - performances. The present invention aims to limit the mass of the internal elements of the box set in motion to assist the engagement of speeds, while limiting the operating sets of the control. For this purpose, it proposes to introduce into the internal control device of the box, a support trolley supported by the control shaft, and driven in translation by this axis during the engagement 10 of a speed while being slidable along the latter, and a spring wound around the axis, which is compressed by the displacement of the carriage by storing energy on a first part of its axis engagement stroke and releases its energy to assist the engagement of the gear on a second part of it. Preferably, the spring is mounted between two rings that slide along the axis, over a determined distance to limit the axial movement of the carriage. The present invention will be better understood on reading the following description of a nonlimiting embodiment thereof, with reference to the appended drawings, in which: FIG. 1 is a view of the proposed device; FIG. 2 is an overall view of the same device with its actuating means and the controlled gear lines; FIG. 3 shows its system for stopping the rotation of the axis of passage, FIGS. show the return means 30 for selecting the device, - Figures 6, 7, 8 and 9 describe the selection and interlock system, - Figures 10, 11, 12, 13, show other aspects of the device. FIG. 14 shows the interfaces with the casing, and FIGS. 15, 16, and 17 illustrate the principle of assisting and assisting shifting. The control device illustrated in FIG. 1 comprises a control shaft 1 driven in translation by a clutch 3, itself driven by an external actuator (see FIG. 2). The axis 1 is mounted in two bearings, and slides in the housing at both ends. It is locked in rotation at one of its ends (on the left in FIG. 1) by a flat surface la, and by an external support element D3 visible in FIG.
    [0002] It also comprises an interlocking key 2, composed of an actuating arm 2a, an angular indexing sector 2b, two angular interlocking sectors 2c, and a tab hold 2d for the recall of the assembly in its central selection position. The interlocking angular sectors 2c are arranged to lock the fingers of the unselected speed lines. The key 2 is free to rotate about the axis 1. The actuating arm 2a is driven by an electromagnet (shown in Figure 2) to move the key 2 in rotation. The angular sector 2b has a hole 2nd oblong circular, visible in Figure 3. A shouldered screw 5, mounted in the housing, is a stop element for the sector 2b, which limits the rotation of the key 2. It cooperates with the tab 2d and the spring 4 , to ensure the recall in selection. The screw 5 also makes it possible to lock the key 2 in translation. In summary, this internal control device comprises a rotary interlocking key 2 adapted to select one of at least two speed lines by simultaneously locking the unselected lines, an internal control pin 1 immobilized in rotation the box housing and driven in axial translation under the control of an external passage control member for engaging speeds on a selected speed line by moving a fork axis to an engaged speed position. A rigid passage carriage 6 is mounted around the axis 1 on bearings 6a, mounted on rings 6e, for example of the "PTFE" type. This carriage has two selection fingers 6b, only one of which is visible in this figure. The carriage 6 is rotated about the passage axis by the interlocking key 2, with which it is in contact with the fingers (see FIGS. 7 and 9). Each finger 6b corresponds to a line of speeds to be actuated. The carriage 6 is supported by the control pin 1. It is driven in translation by this axis during the engagement of a speed, while being able to slide along it. A spring 8, wound around the axis 1, is compressed by the displacement of the carriage by storing energy on a first part of the engagement race of the axis 1. It releases its energy to assist the engagement speed, on a second part of this race. Figure 2 describes in a non-limiting manner the main functional organs of the gearbox cooperating with the proposed control device. The selection actuator is constituted for example by an electromagnet 11, driving the arm 2a in rotation about the passage axis. The passage actuator, driving the clutch 3, may be constituted by a motor 12 driving a trolley by a nut / worm system, or by any other equivalent actuating system. In this figure, there are also: - a shaft line A and a shaft line B, each equipped with a walkman / clabots assembly; a set C composed of a fork C1, an axis C2 and a pin C3, actuating the slider of the shaft line A; - A tilting assembly D consisting of an arm D1 connecting the pin C3 and one of the fingers 2c, a tilting axis D2, and a support D3 (non-limiting form) fixed to the housing; a set E composed of an axis E1, a fork E2 and a clutch E3, actuating the slide of the shaft line B. In FIG. D3 rotation of the axis 1, engaged around the end flat la of the axis 1. This part, which also appears in Figure 2, is the rocker support D which ensures the blocking. However, without departing from the scope of the invention, other types of parts can also ensure the locking in rotation of the axis 1. We also see the sector 2b of the interlocking key, and the second light, limiting the travel of the key 2 around the screw 5.
    [0003] Figures 4 and 5 show the principle of recall in selection. In the rest position of the electromagnet 11 (FIG. 4), the inter-locking key assembly 2 and carriage 6 is in position opposite a selection line, thanks to the spring 4, linked to the key 2 by the tab 2d, and the housing by the shouldered screw 5. When the electromagnet 11 pushes the arm 2a, the key-carriage assembly 2, 6 is driven in rotation about the axis of passage (FIG. ), thus selecting the desired gear line. The angular sector 2b provides the stop function with the shoulder screw 5. The spring 4, driven by the leg 2d, allows the assembly to return to its initial position when the electromagnet no longer acts. During this operating phase, the axis 1 remains motionless in rotation. The carriage 6 carries the selection fingers 6b, visible in FIGS. 6 and 7. These fingers cooperate with the interlocking key 2. The carriage is rotated about the axis 1 by the key 2 of inter -lock 2, when selecting a gear line. Its displacement is ensured by the thrust of the sectors 2c of the key 2, on the fingers 6b. These figures represent the system for selecting speeds in a first selection position. The lower finger 6b is engaged in the clutch E3 to drive it. Adjacent latch area 2c is clear. At the same time, the dog clutch D1 is locked by the other angular sector 2c, while the right finger 6b is free, and can not engage speed. In FIGS. 8 and 9, the same system is in its second selection position: the right finger 6b is arranged to drive the clutch D1, while the adjacent locking sector 2c is disengaged. The clutch E3 is locked by the angular sector 2c of the bottom, while the finger 6b adjacent is free and can not engage speed. Figures 10, 11, 12 and 13 show the control device in front view, and in axial section. FIG. 14 shows the arrangement of the device with respect to the casing of the box, and its interfaces with the casing, in particular at the level of the axis 1 which is supported by two bearings 13, and the shoulder screw 5, screwed into the casing mass. The carriage 6 constitutes a rigid bridge consisting of two end bearings 6a engaged around the axis 1 connected by rigid axial uprights 6d, which allow its axial displacement on the axis 1. A shim 10 is interposed between the passage aid and the carriage 6. The spring 8 is mounted between the two rings 7, which slide along the axis by a determined distance to limit the axial movement of the carriage. The rings 7 are arranged around the axis 1, inside the carriage 6. The spring 8, wound around the axis 1, bears on the rings 7. Each ring has a slot, or slot 7a, cooperating with a pin 9, to limit its sliding on the axis 1. The holes 7a are cut in the material of the rings. The pins are fixed on the shaft (see Figure 15). The pins pass through the lights 7a. When the axis 1 is moved to a gear position engaged, under the control of the electromagnet 12, they allow the carriage to slide on the axis 1, with limited axial movement. The operation of this passage aid system is illustrated in Figures 16 and 17. The carriage 6 is moved under the control of the electromagnet 12. The axis 1, driven by the clutch 3, compresses the spring 8 through the rings 7 and the pins 9. The slot 7a allows the spring 8 to compress. When the spring 8 expands, the assembly 6 is propelled, in addition to performing a race similar to that of the axis. Once the assembly 6 actuated in translation, the speed previously selected and engaged, in one direction or the other. In the rest position, there is contact between the pins 9 and the oblong hole of the rings. This contact is maintained by the spring 8. The shim 10, interposed between one of the rings 7 and the carriage 6, allows to control the clearance between these two elements. By maintaining a small clearance between these two elements, it is possible to suppress the screen forces that may result from the selection movement, if the rings 7 are pushed by the spring 8 and rest on the carriage 6 in the rest position.
    [0004] In conclusion, the invention makes it possible to take advantage of an internal control shaft comprising an interlocking key, and a return device in selection, thanks to the integration of a carriage ensuring the assistance of the assembly. fork claws of the gearbox.
