The invention discloses a four-wheel-drive limited slip differential with an electric control differential lock, which belongs to the technical field of differentials and comprises a differential shell, an inner shell, a planetary gear train, a four-wheel-drive clutch, a four-wheel-drive actuator, a locking clutch and a locking actuator. The inner shell is rotatably arranged in the differential outer shell in a supported mode, the planetary gear train is connected with the inner shell, and the four-wheel-drive actuator acts to drive the four-wheel-drive clutch piece to act so that the differential outer shell and the inner shell can be combined to achieve switching from two-wheel drive to four-wheel drive. The locking actuator acts to drive the locking clutch piece to act so that the differential mechanism shell and the right half axle gear can be combined to achieve differential locking. The differential mechanism further comprises a slip limiting friction plate set arranged between the differential mechanism shell and the right half axle gear, and a pre-tightening spring is arranged between the left end face of the right half axle gear and the planet wheel shaft. The differential mechanism is high in integration level and small in size, the two-wheel-drive and four-wheel-drive switching and differential locking functions can be achieved, and the requirements for rapid turning and low-difficulty escaping can be met without switching operation.

    本发明公开了一种带电控差速锁的四驱限滑差速器,属于差速器技术领域,其包括差速器外壳、内壳体、行星轮系、四驱离合件、四驱致动器、锁止离合件、锁止致动器;内壳体可旋转地承设于差速器外壳内,行星轮系与内壳体连接,四驱致动器作用可带动四驱离合件动作致使差速器外壳与内壳体结合实现二驱到四驱的切换,锁止致动器作用可带动锁止离合件动作致使差速器外壳与右半轴齿轮结合实现差速锁止;还包括设于差速器外壳与右半轴齿轮之间的限滑摩擦片组,右半轴齿轮的左端面与行星轮轴之间设有预紧弹簧。本发明的差速器集成度高,体积小,不仅能实现二驱四驱切换和差速锁止功能,而且无需切换操作就能满足快速过弯和低难度脱困需求。
