Active roll vehicle safety redundancy mechanism and roll motion power-off locking device

The invention relates to an active roll vehicle safety redundancy mechanism and a roll motion power-off locking device, belongs to the technical field of vehicle chassis, is applied to the roll motion control technology of an active roll vehicle, in the driving process of the active roll vehicle, the transverse posture of the vehicle is kept by a roll motor, and the safety redundancy mechanism and the roll motion power-off locking device can be locked when a battery is used up to be powered off or a fault occurs instantly. According to the technical scheme, the vehicle roll movement must be quickly locked to guarantee the personal safety of a driver and passengers, and the adopted key technical measures are that a roll motor is connected with an actuating rod through a speed reducer and an electromagnetic power-off brake to drive the vehicle to roll, so that the roll motor actuation and the vehicle roll movement are realized; when power is cut off, energy application of the roll motor fails, the electromagnet
