Electromagnetic lock-up differential

The invention relates to a differential, in particular to an electromagnetic lock-up differential, comprising a left shell, a right shell, a left axle shaft gear, a right axle shaft gear, a first planetary gear, a second planetary gear, a differential lock, a wave spring, a cam, an electromagnetic generator, a mounting rack and a pusher. The electromagnetic lock-up differential has small axial size, which overcomes the defect of conventional differential utilizing external differential lock has large axial size; the electromagnetic lock-up differential is convenient to control since no hydraulic or pneumatic mechanism is used; development cost is reduced as small modification to the original structure of the differential is needed and most of parts of the conventional differential are kept. 本发明涉及种差速器，尤其是种电磁锁止差速器。其包括:左壳体、右壳体、左半轴齿轮、右半轴齿轮、第行星齿轮、第二行星齿轮、差速锁、波形弹簧、凸轮、电磁发生器、安装架和推杆。它轴向尺寸小，以往采用外置差速锁，轴向尺寸偏大，避免采用液压或气动机构，控制方便；对差速器原有结构改动小，大部分零件可以借用原有差速器零件，降低了开发成本。
