专利摘要:
A locking means fitted within a conventional automotive vehicle type differential housing assembly normally couples the wheel axles to the power rotated housing so that the axles are driven by and rotate with the housing. When either axle rotates faster than the other axle and the housing, the locking means momentarily uncouples the faster rotating axle so that it freewheels, while the other axle continues to be driven. The locking means includes a pair of axially aligned, closely spaced apart coupling rings, each of which surrounds a bushing-like hub mounted upon and axle end portion located within the housing. A diametrically arranged, drive rod of hexagonal cross-section is positioned between the rings and extends through opposite pairs of aligned V-shaped notches formed in the facing ends of the rings. The outer ends of rod are fastened to the housing for rotating therewith. The walls of the notches are parallel to, but slightly spaced from, their adjacent rod faces. Thus, when the rod rotates with the housing, it engages the notch forming walls in its rotational path to rotate the coupling rings and simultaneously wedge them outwardly apart. The coupling rings are connected to the hubs by clutches that engage when the rod moves the rings apart and disengage when the rings move inwardly towards each other. When one axle rotates faster than the housing, its coupling ring advances angularly relative to the rod to disengage its notch forming walls from the rod, which results in its ring moving inwardly towards the other ring to disengage its clutch for freewheeling until its speed returns to housing speed. A limit means keeps the rod centered within the notches when the coupling ring is angularly advanced.

The invention relates to mechanical engineering and can be used as a free-run differential in vehicle transmissions.
The purpose of the invention is to obtain a compact} structure that can be placed in the case of a conventional non-self-locking differential.
FIG. 1 schematically shows the free-run differentiation, transverse JO having a high speed, automatic section; in fig. 2 - the knot, which includes disengaging from the rod, one of the pressure rings with two rod 2, as shown in FIG. 8, where I am; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. 3; in fig. 5 - pressure ring, cross section 15; in fig. 6 - driven sleeve, cross section; in fig. 7 - arrangement of elements when the rod interacts with both pressure collars with the rod and the pressure ring 6. As in this case the load from the rod to the pressure ring 6 is not transmitted, the friction clutch 8 will disengage, which will result in free unloaded rotation of the shaft 4. When this sun load
tsami; in fig. 8 - the location of the elements-20 from the rod 2 will be transmitted through
the pressure ring 5 and the friction clutch 9 to the shaft 3. A limiting device, including studs 16 and sockets 10 and 11, limits the angle of relative rotation of the pressure rings 5 and 6 when one of them disengages from rod 2, due to the Y-shaped notches 12 the disengagement of the corresponding wheels occurs as
in the interaction of the rod with one of the pressure rings.
The freewheel differential comprises a leading body 1, a carrier rigidly connected to it, made in the form of at least one rod 2 with a hexagonal cross section, 25, output shafts 3 and 4 connected to them by splined joints, driven by two coaxial pressure rings 5 and 6, 30 when the car is moving forward, so are the elastic elements backwards that are associated with the latter.

The pressure rings 5 and 6 allow it to be made more compact on the end surfaces reflected to each other, nests 10 and 11 and coaxial Y-shaped grooves 12 and 13, which are joined to the faces of the rod 2, and are connected by means of friction couplings 8 and 9 with driven sleeves 14 and 15.

Invention Formula
The freewheel differential, containing the leading body, is rigidly connected. The differential also contains the means, / jg the carrier with it, output shafts.
A limiting relative angular displacement of the pressure rings 5 and 6, made in the form of studs 16, one end 17 of each of which is fixed to one of the pressure rings, and the other end 18 is freely placed in the corresponding slot of the opposite pressure ring.
Differential free wheeling works as follows .50
the two coaxial pressure rings driven by them through spline joints and elastic elements connected with pressure rings, which are connected with the fact that, with the purpose of obtaining a compact design, are equipped with friction clutches, the carrier is made in the form of at least one rod with a hexagonal cross section, the pressure rings on the face surfaces facing one another have nests and coaxial Y-shaped grooves conjugated to the face of the rod, and are connected by the driven bushing. Rotation of the housing 1 and rigid rods connected to it. s 2 through the surface of the U-shaped recesses 12 is transmitted the pressure ring 5 and 6. When driving the vehicle wheels with the same speed shaft 2 has the same pressure on the pressure rings 5 and 6, as shown in FIG. 7. From push rings
through the friction clutches 8 and 9, the rotation is transmitted to the driven sleeves 14 and 15 and the output shafts 3 and 4 associated with them.
If the rotational speeds of the wheels of the car are not identical, when turning the car or different conditions of adhesion of wheels to the road, the pressure ring associated with the wheel,
having a high speed, automatically disengages from the pin 2, as shown in FIG. 8 where
the pressure ring 6 is disengaged from the rod. Since in this case the load from the rod to the pressure ring 6 is not transmitted, the friction clutch 8 will disengage, resulting in a free unloaded shaft 4. In this case, the load
the pressure ring 5 and the friction clutch 9 to the shaft 3. A limiting device, including studs 16 and sockets 10 and 11, limits the angle of relative rotation of the pressure rings 5 and 6 when one of them disengages from rod 2, due to the Y-shaped notches 12, the disengagement of the respective wheels occurs as
when driving forward, so back.
