The invention particularly discloses a differential mechanism, a driving system and an automobile. The differential mechanism comprises a differential assembly and two speed limiting assemblies, the differential assembly comprises an input end and an output end, and the input end is used for being connected with a driving device; the speed limiting assembly comprises an input gear set, an output gear set and a speed limiting device, the input gear set is connected to the input end, the output gear set is connected to the output end, the speed limiting device comprises a locking piece, a speed limiting rotating piece and a chasing rotating piece, the input gear set is connected with one of the speed limiting rotating piece and the chasing rotating piece, and the output gear set is connected with the other one of the speed limiting rotating piece and the chasing rotating piece; when the rotating speed of the input gear set is the same as that of the output gear set, the locking piece can lock the speed limiting rotating piece and the chasing rotating piece. The rotating speed between the output ends is kept within a certain range, so that the output end corresponding to the non-slip side can keep a certain rotating speed, the influence of wheel slip on an automobile is reduced, and meanwhile the normal steering capacity of the automobile can be kept.
本发明具体公开了一种差速器、驱动系统和汽车。差速器包括差速组件、两组限速组件,差速组件包括输入端和输出端,输入端用于与驱动装置连接;限速组件包括输入齿轮组、输出齿轮组和限速装置,输入齿轮组连接于输入端,输出齿轮组连接于输出端,限速装置包括锁止件、限速转动件和追及转动件,输入齿轮组与限速转动件和追及转动件的其中一个连接,输出齿轮组与另一个连接;其中,当输入齿轮组和输出齿轮组的转速相同时,锁止件能够锁止限速转动件和追及转动件。本发明使输出端间的转速保持在一定范围内,从而让非打滑侧对应的输出端能够保持一定的转速,进而减少汽车受车轮打滑的影响,同时能使汽车保持有正常转向的能力。
