The utility model is described in further detail in conjunction with the accompanying drawings below by embodiment:
As shown in Figure 1, two circular arc elastic press types surmount differential mechanism and comprise that belleville spring 7 between outer 1, two positioning ring 2 of hub of axle shape of a band hub bore and 3, two star-wheels 5, roller 6, two star-wheels and pressure spring 8 pads 9 and two end caps 4 form.Two end cap outer stopper 18 connects by outer hub hub bore 10 location and with bolt, and star-wheel cylindrical 19 can be relatively rotated by end cap inner stopper 17 location, and circle 14 cooperates also and can relatively rotate with star-wheel 5 cylindricals in the positioning ring 2,3.As shown in Figure 2, be evenly equipped with curve bath 20 on star-wheel 5 cylindricals 19, the number of curve bath is the multiple that is loaded on the roller 6 in the restraining groove 13 of positioning ring 2 or 3, positioning ring 2,3 is placed on the star-wheel 5, be provided with it at the positioning ring cylindrical and be complementary, have the outer hub 1 of axle shape of hub bore, be provided with 1-2 millimeter gap between hub bore and the positioning ring, interfere in order to prevent that positioning ring and hub bore from producing, the location and the generation that influence roller 6 are skidded.Be evenly equipped with two circular arcs 11 and 12 on the wall of outer hub hub bore 10 in order to hold roller 6 outstanding positioning rings 2 or 3 part in addition, the diameter of circular arc 12 is equal to or slightly greater than the diameter of roller 6, diameter less than circular arc 11, circular arc 12 is located at the top of circular arc 11 and circular arc 11 is divided into symmetrical two sections, circular arc 11, the axis of circular arc 12 and outer hub 1 is parallel to each other and in same plane, the place is provided with radial hole on circular arc 12 summits, be provided with pressure spring 8 and pad 9 in the hole, its axial position is in the centre or the inboard, two ends of roller 6, roller 6 is pressed in the cylindrical curve bath 20 of star-wheel 5 with it, also can establishes an elastic pressing plate and finish on the restraining groove side of positioning ring.Setting up circular arc 12, is in order to reduce orientation angle as far as possible, alleviating the impact of roller and arc groove 11, and roller and the disengagement of star-wheel cylindrical curve bath when guaranteeing differential.Extremely shown in Figure 6 as Fig. 3, positioning ring 2 is evenly equipped with identical with the roller number with 3 one ends, bi-side are parallel to each other and be symmetrical in the restraining groove 13 of axis, and slot length is equal to or slightly greater than the length of roller 6, and the positioning ring 2 and 3 the other end are respectively equipped with a pair of or several to double wedge 15 or recessed tooth 16.Protruding, recessed tooth bi-side extensions all are not pass through the positioning ring axis by protruding, the recessed tooth of the existing positioning ring bi-side extensions of positioning ring shaft axis, because fast limit positioning ring rotates an orientation angle during differential, protruding, recessed tooth becomes the line contact, very easily distortion, both influenced Location accuracy, and produced with outer hub bore easily again and interfere, aggravation causes skidding, and model utility can guarantee that convex and concave teeth makes contact to the face contact, has eliminated the drawback of prior art.The width of convex and concave teeth represents that with angle the recessed tooth 16 wide double wedges 15 that equal add the twice orientation angle, and definite corner that touches in the circular arc 12 according to roller 6 and circular arc 11 of this angle determines that positioning ring thickness is the 1/2-2/3 of roller 6 diameters.Positioning ring 2 and 3 chimeric mutually by the convex and concave teeth of an end separately.
By following operating analysis, the purpose of this utility model can realize as can be known.
The moment of torsion that the motor vehicle transmission axle transmits, pass to outer hub 1 by the main reducing gear bevel gear pair, make outer hub 1 change a very small angle along the axle center, by arc groove 11 1 sides roller 6 is pushed down again, so outer hub moment of torsion passes to semiaxis by roller 6, star-wheel 5, orders about wheel, thereby Motor Vehicle is advanced or retreat, because the pad at two arc grooves 12 tops of outer hub 1 is controlled in roller 6 in the arc groove of star-wheel 5 cylindricals in advance, so transmitting torque is very reliable.If there is not pad control, often because of roller 6 self gravitations, factors such as centrifugal force and frictional force, Motor Vehicle often makes roller 6 break away from the arc groove of star-wheel cylindricals by state of rest to transmitting torque or by getting back to behind the differential in the transmitting torque process, occur skidding and producing impact, can't transmitting torque.Thereby pressure spring 8 and pad 9 all be in the star-wheel external arc groove can guarantee roller 6 except that differential the time, makes transmitting torque very reliable, perfectly safe.When the motor vehicle straight-line travelling, outer hub clockwise rotates, and drives left and right sides semiaxis and wheel by roller, star-wheel, vehicle is advanced, otherwise then fall back.At this moment the positioning ring double wedge is in the neutral position of recessed tooth, when Motor Vehicle is turned since outside wheel speed fast, interior wheel speed is slow, fast steamer drives fast limit star-wheel roller by semiaxis, positioning ring is with respect to orientation angle of the many commentaries on classics in slow limit, the convex-concave flank of tooth contact of two positioning rings, at this moment outer hub orthodrome 11 is only pushed down the roller transmitting torque on slow limit, and the positioning ring on fast limit is limited to the roller on fast limit the neutral position of the two circular arcs of outer hub just, fast limit star-wheel then ejects its roller when fast steamer continues fast the commentaries on classics, and make it become freewheel, realize differential, in fact, as long as the roller on fast limit leaves outer hub orthodrome wall, fast steamer becomes freewheel immediately, so the utility model differential does not have the sideslip phenomenon flexibly.When driving wheel of Motor Vehicle is in good road surface, and another driving wheel is when falling into pitfall or slippery ground, the countertorque that the wheel that fall into pitfall or slippery ground this moment acts on differential mechanism is very little, so the moment that it only is assigned to is seldom kept wheel slip, most moment loading goes to the driving wheel that is in good road surface, the defective that this has just overcome present differential mechanism moment of torsion mean allocation makes vehicle climb out of pitfall, and the advantage that overcomes wheel-slip is very remarkable.For overcome vehicle starting, fall back and running process in step under the situation such as clutch, the existence of twice orientation angle is arranged to right side nip drum post because of outer hub orthodrome left side nip drum post, cause roller when contact vehicle of orthodrome 11 that more weak impact takes place, the utility model adopts increases belleville spring between two star-wheels, make star-wheel give end cap an axial force, when outer hub is rotating a small angle, when its orthodrome contacts with roller, end cap and star-wheel produce relative rotation simultaneously, axial force then is converted into friction torsion, play buffer function, thereby overcome shock problem.From above-mentioned situation as can be known the utility model designs simplification, make easily, cost is low, reliable performance is a kind of novel differential mechanism that surmounts of practicality.
