A planetary tapered spiral wheel is arranged on a planetary tapered spiral shaft; the planetary tapered spiral shaft is fixed on the differential shell; the power input head of the half shaft is provided with a half-shaft tapered spiral wheel; two half-shaft tapered spiral wheels are symmetrically arranged in the differential shell and the planetary tapered spiral wheel is meshed between two half-shaft tapered spiral wheels. The utility model has the advantages of simple and compact structure as well as convenient production and installation. The balanced antiskid differential mechanism can not only achieve the antiskid effect but also have equal torque, thus being applied in rear-wheel differential, front-wheel differential and even jackshaft differential.
Description
One, technical field:
The utility model relates to for motor vehicle differential mechanism, is a kind of balance limited slip differential.
Two, background technique:
At present, automobile is a lot of with the differential mechanism kind, as People's Transportation Press's the 156th to 171 page of principle and some differential mechanisms of having put down in writing differential mechanism of automobile construction volume two in 2003 the 4th time publication, Hyundai Motor adopts compensating gear more, as shown in Figures 1 and 2, disclose a kind of symmetric type (promptly waiting torque type) bevel differential of non-antiskid, it comprises differential carrier, planetary pinion, planetary wheel carrier axle, semiaxis and power input gear; When the condition of adhering between left and right or forward and backward driving wheel and the road surface of running into differs bigger situation, use compensating gear, wheel easily skids, and can not guarantee automobile to obtain enough tractive force and advance.And existing antiskid differential mechanism all is asymmetric formula (promptly not waiting torque type), thereby is unfavorable for the differential of f-w-d vehicle.
Two, summary of the invention:
The utility model provides a kind of balance limited slip differential with symmetric type of skid resistance, and it has solved the problem of torque types such as can preventing that wheel-slip has again.
The technical solution of the utility model realizes by following measure: a kind of balance limited slip differential, comprise differential carrier, semiaxis and power input gear, planet cone screw line wheel is installed on planet cone screw line wheel shaft, planet cone screw line wheel shaft is fixedly mounted on the differential carrier, be installed with semiaxis tapered auger line wheel on the power input head of semiaxis, and two semiaxis tapered auger line wheels are installed in the differential carrier symmetrically, and planet cone screw line wheel is engaged between two semiaxis tapered auger line wheels.
Between above-mentioned semiaxis tapered auger line wheel and planet cone screw line wheel and differential carrier, thrust washer can be installed.
Between above-mentioned planet cone screw line wheel and planet cone screw line wheel shaft, spherical pad can be installed.
Above-mentioned planet cone screw line wheel shaft can be fixedly mounted on the differential carrier by fixed hole.
That above-mentioned planet cone screw line wheel shaft can be direct shaft type or Cardon universal joint.
The utility model simple and compact structure is convenient to make and is installed, and utilizes this balance limited slip differential not only can realize antiskid, but also torque such as has, and so both can be used for the trailing wheel differential, also can be used for the front-wheel differential, also can be used for the jackshaft differential.
Four, description of drawings:
Accompanying drawing 1 is the structure sectional view of existing symmetric type compensating gear,
Accompanying drawing 2 is existing symmetric type bevel differential parts explosion;
Accompanying drawing 3 is for the master of most preferred embodiment of the present invention looks the broken section structural representation,
Accompanying drawing 4 is the side-looking assembly structure schematic representation that takes down a side differential carrier in the accompanying drawing 3,
Coding in the accompanying drawing is respectively: 1 is planetary pinion, 2 is semiaxis tapered auger line wheel, 3 and 6 is semiaxis, and 5 is differential carrier, and 7 is power input gear, 8 is planetary wheel carrier, 9 and 10 is thrust washer, and 11 is spherical pad, and 12 and 13 is fixed hole, 14 is planet cone screw line wheel, and 15 is planet cone screw line wheel shaft.
Five, embodiment:
The utility model is not subjected to following embodiment's restriction, can determine concrete mode of execution according to the technical solution of the utility model and actual conditions.
Below in conjunction with most preferred embodiment and accompanying drawing the utility model is further described:
Shown in accompanying drawing 1 to 4, the utility model is the improvement to existing symmetric type (promptly waiting torque type) bevel differential, make it have cling property, this balance limited slip differential comprises differential carrier 5, semiaxis 3 and 6, power input gear 7, take turns 14 and be set with planet cone screw line on the planet cone screw line wheel shaft 15, planet cone screw line wheel shaft 15 is fixedly mounted on the differential carrier 5, be installed with semiaxis tapered auger line wheel 2 on semiaxis 3 and 6 the power input head, and two semiaxis tapered auger line wheels 2 are installed in the differential carrier 5 symmetrically, and planet cone screw line wheel 1 is engaged between two semiaxis tapered auger line wheels 2.
During work: power is exported to driving wheel through differential carrier 5, planet cone screw line wheel shaft 15, planet cone screw line wheel 14, semiaxis tapered auger line wheel 2, semiaxis 3 and 6 successively from power input gear 7; When both sides wheel during with identical rotational speed, 14 the rotational-revolution of planet cone screw line wheel around semiaxis 3 and 6; When both sides resistance wheel difference, then planet cone screw line wheel 14 is when making above-mentioned revolution motion, and also around self rotational-rotation, thereby semiaxis tapered auger line wheel 2 drive both sides wheels rotate with different rotating speeds; When the condition of adhering between left and right or forward and backward driving wheel and the road surface of running into differs bigger situation, as left side wheel unsettled or enter road surfaces such as mire, ice and snow and right side wheels in frictional force preferably during the road surface, then planet cone screw line wheel 14 is when making above-mentioned revolution motion, also around self rotational-rotation, and, make right side wheels that enough tractive force still be arranged and automobile is advanced because planet cone screw line wheel 14 interacts with a left side and right two semiaxis tapered auger lines wheel 2; So just realized antiskid.
In order to reduce friction and the adjusting play, shown in accompanying drawing 3 and 4, between semiaxis tapered auger line wheel 2 and the differential carrier 5 thrust washer 9 and 10 are installed, between planet cone screw line wheel 14 and planet cone screw line wheel shaft 15 and the differential carrier 5 spherical pad 11 are installed.Shown in accompanying drawing 3 and 4, planet cone screw line wheel shaft 15 is fixedly mounted on the differential carrier 5 by fixed hole 12 and 13, also can select other means of fixation according to actual needs.Shown in accompanying drawing 1 to 4, planet cone screw line wheel shaft can be direct shaft type, also can be Cardon universal joint, and is selected according to actual needs.
The most preferred embodiment of the present utility model that above technical characteristics has constituted, it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characteristics according to actual needs.
