Abstract
The utility model relates to an automatic clutch differential mechanism. The utility model is characterized in that the inner part of a casing 3 is provided with a star wheel 4, a holding ring 5 and a roller 6, and the roller and the holding ring are positioned between the star wheel and the casing; the inner wall of the casing is provided with a concave arc groove face; the cross section of the inner ring of the star wheel is a splined face, and the cross section of the outer ring is a convex-concave interphase arc face; the roller is arranged in the locating groove of the holding ring and limited in a concave arc groove of the inner ring of the casing. The utility model changes the cone tooth meshing into the automatic clutch of the roller. The structure is compact and simple, and the use is safe and reliable. The utility model can overcome the phenomenon that the driving force is decreased because of the slippage on the pavement, and can realize the safe and steady running of the automobile on the bad pavement or when turning at high speed.
Description
The utility model relates to a kind of vehicle planetary compensating gear, particularly a kind of differential gear of automatic clutch.
Continuous development along with modern industry, automobile is the most general transport facility in the world today, and present automobile all is to adopt four intermeshing satellite differentials of angular wheel basically, and the constant speed or the differential that satisfy automobile with this differential mechanism travel.Because the torque distribution of the wheeled differential mechanism of common conical tooth is even, and condition each other, thereby, when descending, the adhesion on the driving wheel of automobile one side and road surface produces when skidding, the driving wheel of opposite side also is affected thereupon, the moment that is obtained is not enough to drive automobile running, and therefore, the ability that automobile runs over bad road surface is restricted.In addition, when automobile high-speed is turned, trackslip owing to weight offset forms the decline of interior wheel adhesion, thereby cause the automobile driving force to weaken, energy loss increases, and the maneuverability of automobile is interfered.
This practical purpose provides a kind of differential gear of automatic clutch, and the engagement of screwdriver tooth overcomes the phenomenon that reduces driving force because of slipperiness on roads for the roller automatic clutch, realizes that the safety and steady of automobile on bad road surface travels.
The purpose of this utility model is achieved in that in comprising the differential mechanism of big flange plate, removes angular wheel, increases star-wheel, positioning ring, roller etc., and its structure outline is: 1. big flange plate is positioned at of housing, and small flange plate is arranged in the other end of housing; 2. two groups of star-wheels, positioning ring and rollers are installed in housing, and wherein roller and positioning ring are between star-wheel and housing; 3. the concave arc groove face is arranged on the inwall of housing; 4. the interior ring cross-section of star-wheel is a spline surface, and outer ring cross-section is the alternate cambered surface of convex-concave; 5. roller is installed in the locating slot of positioning ring, is limited in the inner walls concave arc groove.
Big flange plate of the present utility model is connected with retarder driven gear on the automobile, and the left and right sides semiaxis on the automobile in the ransaxle inserts respectively in two star-wheels of the present utility model, and the spline surface of star-wheel inner ring meshes with semiaxis.When motor spreads out of moment of torsion and delivers to driven gear on the retarder, driven gear drives big flange plate rotation, big flange plate drives housing again and rotates, the inwall concave arc groove face of housing promotes roller and rotates, roller drives star-wheel again and rotates, star-wheel drives semiaxis and rotates in the lump, and the wheel that is installed on the semiaxis rotates thereupon, thereby realizes the constant-speed driving of automobile.When the wheel of automobile one side and the adhesion between ground descend and when skidding, its rotating speed of automobile axle shaft high speed rotating is greater than the rotating speed that transmits from big flange plate, at this moment, semiaxis drives the star-wheel high speed rotating, with the contacted roller of star-wheel, under star-wheel promotes, jack-up, fall into the gap of housing intrados, roller leaves inner walls (not amplexiforming mutually) at this moment, and it produces instantaneous rotation with star-wheel.Therefore, housing can be because of wheel-slip change rotating speed, and it only is subjected to the influence of engine speed.On the other hand, two groups of star-wheels are arranged in the housing, and the wheel semiaxis is inserted in respectively in separately the star-wheel, therefore, when single wheel skids, opposite side wheel and unaffected, the torque force effect that it is spread out of by motor still, this has just overcome the opposite side that skids of satellite differential single wheel in the prior art and just has been not enough to the shortcoming of travelling.
Adopt such scheme, compact structure, simple, safe and reliable, constant speed and differential that it can satisfy automobile travel, and can reduce the energy loss in the vehicle transmission again, improve cross country power.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 1, Fig. 2 also are embodiments of the present utility model.
As seen from Figure 1, Figure 2: the utility model is made up of small flange plate 1, big flange plate 2, housing 3, star-wheel 4, positioning ring 5, roller 6, and their annexation is: 1. big flange plate 2 is positioned at of housing 3, in the other end of housing 3 small flange plate 1 is arranged; 2. two groups of star-wheels 4, positioning ring 5 and roller 6 are installed in housing 3, and wherein roller 6 and positioning ring 5 are between star-wheel 4 and housing 3; 3. the concave arc groove face is arranged on the inwall of housing 3; 4. the interior ring cross-section of star-wheel 4 is a spline surface, and outer ring cross-section is the alternate cambered surface of convex-concave; 5. roller 6 is installed in the locating slot of positioning ring 5, is limited in the concave arc groove of housing 3 inwalls.
As shown in Figure 2,6 rollers 6 are installed in one group of star-wheel 4 and positioning ring 5.In conjunction with Fig. 1 as can be known, two groups of star-wheels 4 and positioning ring 5 are installed in the housing 3, so, 12 rollers 6 are installed altogether in housing 3.
