    The invention relates to a transport mechanical engineering, in particular, to drives of driving axles of vehicles.
    A device is known for simultaneously controlling the differential lock and the drive of the driving front axle, comprising an axially movable clutch mounted on the front drive axle drive shaft in the form of a sleeve with splines on the outer surface for communication with the elements of the center differential and clutch controls ζΐ].
    The disadvantages of the known device are the complexity of the design and the inconvenience of control for the driver, which consists in the fact that the inclusion of the front axle and the differential is provided by two different mechanisms, and with the help of the first, the coupling is shifted to engage
    FOR SIMULTANEOUS MANAGEMENT OF DIFFERENTIAL AND THE FRONT AXLE DRIVE · the middle bridge, and the second - blocking of interaxal differential.
    The purpose of the invention is to simplify the design and facilitate control of the driver.
    This goal is achieved in that the device is equipped with an additional sleeve. with splines on the outer surface mounted on said shaft by means of splined connection, while the inner surface of the coupling in its middle part is smooth, and at its ends with splines, between which there are splines of the outer surface of the additional sleeve.
    In FIG. 1 shows a device, a longitudinal section; in FIG. 2 - node 1 in figure 1 (in the neutral position).
    A drive gear 1 is installed in the crankcase of the bridge, mounted on the shaft 2, which is placed in two tapered bearings relative to the crankcase. The shaft 2 is connected with splines
    939308 4 housing 3 interaxle differential mounted in the crankcase of the bridge on the ball bearing 4, and transmits rotation from the gear 1. The housing 5 of the front axle drive is fixed in- ! 5 crankcase bridge. In the support 6, a front drive leash 7 is fixed, connected by internal splines to the shaft 8, by means of which the axial differential of the front axle not shown is actuated. On the leash there are external slots 9 and a sleeve 10 along which the coupling 11 with the spline surfaces moves.
    and 13 · This coupling interacts 15 using a well-known mechanism 14 through the pin 15, the guide pin 16 and the plug 17 · The coupling 11 is connected to the slots 18 of the housing 3 of the center differential via splines 19 The sun gear 20 of the center differential is also connected by means of splines to the hollow shaft 21, which passes through shaft 2 and is connected at its opposite end to the axle 25 differential of the first rear axle (not shown). The sun gear 22 of the center differential has external splines 23, which are connected through internal splines 24 and a shaft 25, 30 connected to the axial differential of the second rear axle (not shown).
    The device operates as follows.
    The control mechanism 14 via the HA 35 directs trunnions 15 and 16 and the fork 17 acts on the coupling 11, which through the hub 10 is moved so that the slots 13 are introduced into the slots 23. on the sun gear 40 of the 22 inter-differential, and as a result, it ceases to function - it is blocked. With further displacement of the clutch 11 in the same way, the splines 12 are connected with the splines 9 of the front drive 7 lead 7, as a result of which the drive is turned on. ·
    The invention allows one body to simultaneously control both the differential lock clutch and the front axle drive, which greatly facilitates the work of the driver.

    body 3 of the center differential installed in the crankcase of the bridge on a ball bearing, and transmits it to the rotation of gear 1. The housing 5 of the front axle drive is fixed in the crankcase of the bridge. In support 6, a front-wheel drive driver 7 is fixed, connected by internal splines to shaft 8, by means of which a not shown axial differential of the front axle is actuated. On the leash there are external splines 9 and a bushing 10, along which the coupling 11 with the splined surfaces moves. 12 and 13. This clutch communicates via a known mechanism 14 through a trunnion 15, guiding trunnion 1 and a plug 17. Coupling clutch 11 is connected with splines 18 of housing 3 of the center differential through splines 19 Sun gear 20 of the center differential also using splines St. A hollow shaft 21 that passes through the shaft 2 and its opposite end is connected with the axial differential of the first rear axle (not shown). The sun gear 22 of the center differential has external splines 23 which are connected through internal splines 24 and a shaft 25 connected with an axial differential of a second rear axle (not shown). The device works as follows. way .. The control mechanism 14 through the guide pins 15 and 16 and the plug 17 acts on the coupling 11, which moves along the sleeve in such a way that the splines 13 are inserted into the splines 23 on the sun gear 22 of the differential gear, and as a result ceases to function - is blocked. With further displacement of the coupling 11 in the same way, the splines 12 are connected to the splines 9 of the driver 7 of the front drive, as a result of which the drive is activated. The invention allows one body to control both the differential lock clutch and the middle axle drive, which greatly simplifies the driver’s work. Apparatus of the Invention A device for simultaneous control of a differential lock and drive of a leading front axle, comprising an axially movable coupling mounted on a drive shaft of a front drive axle in the form of a sleeve with slots on the outer surface for coupling with elements of an axial differential and coupling controls different so that, in order to simplify the design and facilitate driver control, it is equipped with an additional sleeve with slots on the outer surface mounted on the m shaft through a spline connection, while the inner surface of the coupling in its middle part is made smooth, and at its ends - with slots, between which are the splines of the outer surface of the additional sleeve.
