    专利说明:

    The invention relates to transpor Nome mechanical engineering, in particular to samoblokiruk tsims differentials driving axles of vehicles known samoblokirukvdiys differential driving of the vehicle axle, comprising a conical pinion gear in the housing, multiplate friction clutch discs which are biased relative to the gear housing, and reversion hydrochloric overrunning clutch leading and the driven elements of which are kinematically connected with the gearbox housing and one of the half-axle gears tlj. A disadvantage of the known differential is the proportionality of the additional moment of friction to the torque of the main gear. This leads to a low efficiency of this kind of solutions in conditions of poor adhesion of the drive wheels, when the moment on the mechanism case is of little importance, driving in an arc. It occurs with an asymmetrical distribution of moments on the drive wheels, which makes it difficult to control the car. The purpose of the invention is to increase efficiency by increasing the internal friction torque in the differential. The goal is achieved by the self-locking rudder differential of the vehicle drive axle containing a bevel gear reducer in the housing, a multi-plate friction clutch, the discs of which are spring-loaded relative to the gearbox housing / and the reversing overhang clutch, velocities and driven elements of which are kinematically connected with the gearbox housing and one of the semi axle gears, fitted with mounted on the floor an additional cone friction clutch, the leading and driven elements of which are connected respectively to the differential casing and the separator of the rolling elements of the reversible bgon clutch, and the pusher cam mechanism, the cam of which is connected with the axle casing and joined in the form of a disk with an end profile surface pits, and the pushers are spring-loaded relative to the differential case to interact with the cam surface, the pushers being connected with the other end to the vedomel1 conical element the friction clutch, the number of pushers is equal to the number of recesses of the profile surface of the cage and the driving element of the reverse free-wheel clutch is connected with the driven disks of the friction clutch. FIG. 1 schematically shows a differential mechanism, an axial section; in FIG. 2 shows section A-A in FIG. one; in fig. 3 - node I in figure 1. The differential contains a multi-plate friction clutch, the outer hub 1 of which, being part of the body of this mechanism, is connected to the inner hub 2 through the inner friction discs 3 and the outer friction discs 4, outside of which are located the helical pressure springs 5. Inside the inner hub 2 on the half-axis 6, a polygonal sleeve 7 is fixedly mounted in such a way that rolling bodies 8 in the form of rollers 8, which are straight, are placed between its walls and the cylindrical surface of the inner hub 2 with some radial clearance and the aid of the separator 9 and its centering device 10 are kept in a symmetric position relative to the walls of the polygonal sleeve 7. In addition, the separator 9 is equipped with a friction part with a flange, preferably shaped as a cone, which is planted in the conical hole of the differential housing. The flange of the separator 9 is in contact with the pressure disk 11, which is in contact with the pushers 12, preferably two, preferably two, the second ends of which are in contact with the end cam 13, fixedly mounted on the body of the bridge 14, and the end surface of the cam has recesses evenly spaced around the perimeter, the number of which is equal to the number of pushers 12. A disk 15 is connected to the pushers 12, and tension springs 16 are placed between it and the body. During driving along a straight line, the mechanism body and The semi-axis 6 rotates at the same speed, at which the polygonal sleeve 7, the rollers 8, the separator 9 and the pressure disk 11 also rotate, the latter performing small axial movements in addition to the rotational movement, caused by the interaction of the pushers 12 with the face surface of the cam 13. These movements cause periodically frictional adhesion of the separator to the housing. When driving in an arc, due to the occurrence of a periotic friction moment, the separator 9 together with the rollers 8 periodically rotate at a certain angle relative to the polygonal sleeve 7, and the shape and dimensions of the cam 13 and the size of the radial clearance of the rollers 8 are selected in such a way that their angle of rotation too small for the rollers to jam. 8. In case of exceeding the limit value of the ratio of rotational speeds
    drive axles, which can take place only with significant slipping of one of the wheels, the separator 9 together with the rollers 8 rotates relative to the polygonal sleeve 7 to an angle at which the rollers 8 are jammed and connected through the half-axle semi-axle friction clutch that is unambiguous with a significant increase in the moment of internal friction of this mechanism.
    The separation of the axle shaft 6. and the hub 2 occurs as a result of a change in the direction of torque transmission by the rollers 8, i.e. in the case of the disappearance of forces, keeping them in a wedged state. After release of the rollers 8, they are installed in a position that is symmetrical relative to the planes of the polygonal sleeve 7, which occurs under the influence of the spring centering device 10. The differential works when slipping any of the drive wheels when moving forward or backward.
    The differential has the merit of a typical differential mechanism, i.e. gives approximately the same tractive force on both under normal operating conditions, and also has the property of significantly increasing internal friction in the event of loss of adhesion by one of the wheels, due to the sudden increase in the internal friction torque, which gives better use of the adhesion of the drive wheels. The very same temporary increase in internal friction causes a slight wear on the device itself, which increases internal friction and low tire wear. In addition, the advantage of the proposed mechanism is the good controllability of the vehicle, as well as the fact that the differential mechanism performs its function when slipping any of the wheels, both when driving forward and when moving backward.
