At present in motor drive system work process, it is common that by planetary gear in differential assembly and differential carrier
The assembly synergistic such as body and travelling gear coordinates the transport conditions such as straight line or the turning to realize vehicle, when beating occurs in unilateral wheel
Time sliding, the most more widespread practice is to suppress wheel spin by assembling torsional differential gear or clutch-plate anti-sideslip differential mechanism
Skid, it is ensured that normal vehicle operation.But, although above two differential mechanism can solve the problem that the problem that wheel spin is skidded, but holds in the palm
The use cost of gloomy differential mechanism itself is higher, and the internal circuit of clutch-plate anti-sideslip differential mechanism control assembly is more, uses wind
Danger and use cost are higher, the phenomenon such as easily occur clutch-plate overheated in work process, constrain the service life of differential assembly
And service behaviour.
Therefore, a kind of differential assembly how is provided so that it is be prevented from wheel spin and skid, and cost is relatively low, performance
It is stably those skilled in the art's important technological problems that solution is presently required.
Utility model content
The purpose of this utility model is to provide a kind of differential assembly, and this differential assembly is prevented from wheel spin and beats

Motor-car.
For solving above-mentioned technical problem, this utility model provides a kind of differential assembly, including the drivewheel cooperated,
Driven pulley and housing, described enclosure interior is provided with two differential gears, and differential gear described in two is the most corresponding
Be arranged at the both sides of described drivewheel axis；
Described differential gear includes the planetary gear matched with described housing, also includes and described planetary gear phase
The travelling gear coordinated and fixed gear, the outside of described differential gear is additionally provided with matches with described travelling gear
Power transmission shaft.
Preferably, described fixed gear is positioned at the inner side of described differential gear.
This utility model also provides for a kind of motor vehicles, including car body, is provided with differential assembly, described difference in described car body
Speed device assembly is specially the differential assembly as described in above-mentioned any one.
The most above-mentioned background technology, differential assembly provided by the utility model, in its work process, drivewheel drives
Driven pulley rotates, and driven pulley drives planetary gear to rotate around the axis of travelling gear by housing, and now fixed gear does not rotates,
Planetary gear band nutating gear rotates, and travelling gear drives power transmission shaft to rotate, and power transmission shaft band motor car wheel rotates.Owing to being provided with
Two differential gears, will not influence each other between two differential gears, when unilateral wheel generation skid phenomenon, separately
The differential gear that single wheel matches normally works, and the wheel of the side that makes not skid normally works, it is ensured that vehicle is normal
Travel.
