The invention discloses a redundant novel ring and ball type electric steering gear which comprises a turbine, a main worm, an auxiliary worm, a main motor and an auxiliary motor, the main worm is arranged on one side of the turbine, and the main worm is meshed with the turbine; the auxiliary worm is arranged on the other side of the turbine, and the auxiliary worm is also meshed with the turbine; the main motor is connected with the main worm, and the main motor drives the main worm to rotate; the auxiliary motor is connected with the auxiliary worm, and the auxiliary motor drives the auxiliary worm to rotate. The two motors are arranged to control the two worms to be engaged with the turbine so that the steering device can be independently controlled, and the situation that operation cannot be conducted when one electric controller breaks down is prevented.
本发明公开了一种冗余新型环球式电动转向器,包括:涡轮、主蜗杆、副蜗杆、主电机和副电机,所述主蜗杆设于所述涡轮的一侧,所述主蜗杆和所述涡轮相啮合;所述副蜗杆设于所述涡轮的另一侧,所述副蜗杆也和所述涡轮相啮合;所述主电机和所述主蜗杆连接,所述主电机驱动所述主蜗杆转动;所述副电机和所述副蜗杆连接,所述副电机驱动所述副蜗杆转动。本发明设置两个电机控制分别控制两个蜗杆分别与涡轮啮合进而可以独立控制转向装置,以防止出现一个电动控制器出现故障就无法操作的情况。
