Speed reducer shell with external idling start-stop energy accumulator control oil way

The invention discloses a speed reducer shell with an external idling start-stop energy accumulator control oil way, and belongs to the technical field of speed reducers. A valve body control oil way and an energy accumulator actuator oil way are arranged in the shell body, the valve body control oil way and the energy accumulator actuator oil way are communicated through an external oil way, and the external oil way is fixed to the outer wall of the shell body. Detection sensors are arranged at the communication position of the external oil way and the valve body control oil way and the communication position of the external oil way and the energy accumulator actuator oil way. According to the idling start-stop energy accumulator, the control oil way of the idling start-stop energy accumulator is guided to the outer side of the shell, the complexity of the interior of the shell is simplified, the mold design and manufacturing difficulty in the casting process is reduced, and casting defects and extra machini
