The invention relates to the technical field of power takeoff devices, in particular to a power takeoff device driving circuit structure. Comprising a gearbox controller; the power takeoff switch is controllably connected between the first input end of the gearbox controller and a power supply voltage; the first end of a coil of the first relay is grounded, and the second end of the coil of the first relay is controllably connected with the power supply voltage through the power takeoff switch; the first end of a coil of the second relay is connected with the output end of the gearbox controller, and the second end of the coil of the second relay is connected with the power supply voltage; and the power takeoff actuator is connected with the output end of the driving valve body. The power takeoff driving circuit structure is optimized by additionally arranging the relay, current intervention between the power takeoff switch and the control valve body is avoided, and the service life of the power takeoff switch is prolonged.

    本发明涉及取力器技术领域,具体涉及一种取力器驱动电路结构。包括,变速箱控制器;取力器开关,可控制地连接在所述变速箱控制器的第一输入端和一供电电压之间;第一继电器,所述第一继电器的线圈第一端接地,所述第一继电器的线圈第二端通过所述取力器开关可控制地连接所述供电电压;第二继电器,所述第二继电器的线圈第一端连接所述变速箱控制器的输出端,所述第二继电器的线圈第二端连接所述供电电压;取力器执行器,连接所述驱动阀体的输出端。本发明通过增设继电器优化取力器驱动电路结构,避免取力器开关和控制阀体之间的电流干预,提高取力器开关的使用寿命。
