Description
The differential mechanism that the utility model automobile is used is a kind of balance antiskid differential mechanism.
At present, automobile is a lot of with the differential mechanism kind, as People's Transportation Press's the 145th to 155 page of principle and some differential mechanisms of having put down in writing differential mechanism of automobile construction volume two in publication in 1997, 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, 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.
In view of the problem of above-mentioned existence, the purpose of this utility model is to design a kind of balance antiskid differential mechanism of torque type such as can prevent that wheel-slip has again.
The purpose of this utility model realizes by following measure: this balance antiskid differential mechanism comprises differential carrier, planetary pinion, planetary wheel carrier, semiaxis and power input gear, and on the axle of planetary wheel carrier, be set with planetary pinion, be fixedly mounted on the differential carrier after two planetary wheel carrier butt joints, be installed with semiaxis circular cone arc spiral lamination wheel on the power input head of semiaxis, and two semiaxis circular cone arc spiral lamination wheels are installed in the differential carrier symmetrically, and planetary pinion is engaged between two semiaxis circular cone arc spiral lamination wheels.Between semiaxis circular cone arc spiral lamination wheel and the differential carrier Thurst washer is installed.Between planetary pinion and the planetary wheel carrier spherical pad is installed.Planetary wheel carrier is fixedly mounted on the differential carrier by fixed hole.
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 the main TV structure sectional view of the utility model most preferred embodiment,
Accompanying drawing 4 is the side-looking sectional structure schematic representation of accompanying drawing 3,
Coding in the accompanying drawing is respectively: 1 is planetary pinion, and 2 is semiaxis circular cone arc spiral lamination wheel, and 3 and 6 is semiaxis, and 5 is differential carrier, and 7 is power input gear, and 8 is planetary wheel carrier, and 9 and 10 is Thurst washer, and 11 is spherical pad, and 12 and 13 is fixed hole.
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 that existing symmetric type bevel differential is promptly waited the torque type bevel differential, this balance antiskid differential mechanism comprises differential carrier 5, planetary pinion 1, planetary wheel carrier 8, semiaxis 3 and 6, power input gear 7, and on the axle of planetary wheel carrier 8, be set with planetary pinion 1, be fixedly mounted on the differential carrier 5 after two planetary wheel carrier 8 butt joints, be installed with semiaxis circular cone arc spiral lamination wheel 2 on semiaxis 3 and 6 the power input head, and two semiaxis circular cone arc spiral lamination wheels 2 are installed in the differential carrier 5 symmetrically, and planetary pinion 1 is engaged between two semiaxis circular cone arc spiral lamination wheels 2.
During work: power is exported to driving wheel through differential carrier 5, planetary wheel carrier 8, planetary pinion 1, semiaxis circular cone arc spiral lamination wheel 2, semiaxis 3 and 6 successively from power input gear 7; When both sides wheel during with identical rotational speed, planetary pinion 1 is around the rotational-revolution of semiaxis 3 and 6; When both sides resistance wheel difference, then planetary pinion 1 is when making above-mentioned revolution motion, and also around self rotational-rotation, thereby semiaxis circular cone arc spiral lamination 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 planetary pinion 1 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 planetary pinion 1 interacts with a left side and right two semiaxis circular cone arc spiral laminations wheel 2; So just realized antiskid.
In order to reduce friction and the adjusting play, shown in accompanying drawing 3 and 4, between semiaxis circular cone arc spiral lamination wheel 2 and the differential carrier 5 Thurst washer 9 and 10 are installed, between planetary pinion 1 and the planetary wheel carrier 8 spherical pad 11 is installed.Shown in accompanying drawing 3 and 4, planetary wheel carrier 8 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.
The utility model simple and compact structure utilizes this balance antiskid differential mechanism 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.
