The invention belongs to the technical field of mechanical transmission and provides a novel pure rolling type automobile differential mechanism. A straight tooth bevel gear is arranged outside an outer tooth inner cam, and a biphase inner cam is arranged in the outer tooth inner cam. Power is input through the bevel gear outside the outer tooth inner cam and transmitted to a movable type sleeve roller through the biphase inner cam of the outer tooth inner cam, and then the movable type sleeve roller transmits the power to a left half axle frame fixedly connected with a left wheel and a right half axle center wheel fixedly connected with a right wheel, so that a differential speed between the left wheel and the right wheel is achieved. According to the pure rolling type automobile differential mechanism, a planetary gear system in a traditional automobile differential mechanism is omitted, and the movable type sleeve roller is connected with the left half axle frame, the outer tooth inner cam and the right half axle center wheel in a rolling contact mode, so that the structure is more compact, the size is small, and the weight is light; multiple teeth are engaged, the contact ratio is large, the bearing capability is high, and transmission efficiency is high; the pure rolling type automobile differential mechanism can be widely applied to various wheeled vehicles needing differential mechanisms, for example, common automobiles and engineering vehicles.
