The invention discloses an any tooth difference type internal shock automobile differential provided with a double-roller block and belongs to the technical field of mechanical transmission. According to the novel automobile differential, a bevel gear is arranged outside an outer tooth internal retainer, and a sleeve structure is arranged in the outer tooth internal retainer; power is input through the bevel gear outside the outer tooth internal retainer and transmitted to the double-roller block through the sleeve structure of the outer tooth internal retainer, and then the double-roller block transmits the power to a left half axle central wheel fixedly connected with left wheels and a right half axle multi-phase internal cam fixedly connected with right wheels, so that the speed difference between the left wheels and the right wheels is achieved. According to the differential, a planetary gear system in a traditional automobile differential is omitted, and the double-roller block is in multi-tooth engagement with the left half axle central wheel, the outer tooth internal retainer and the right half axle multi-phase internal cam and is also in rolling engagement with the outer tooth internal retainer, so that the differential is compact in structure, small in size, low in weight, capable of achieving multi-tooth engagement, large in overlap ratio, high in bearing capacity, high in transmission efficiency and can be widely applied to various wheeled vehicles, such as automobiles and engineering vehicles, needing differentials.
