The invention relates to the technical field of vehicles, and particularly discloses an overload alarm exhaust device, an overload prevention alarm control method and a vehicle, the overload alarm exhaust device comprises a connecting valve body, and a first communication hole and a second communication hole are formed in the outer side wall of the connecting valve body at intervals; one end of the bypass pipeline is communicated with the first communication hole, the other end of the bypass pipeline is blocked to form a buffer cavity in the pipeline, and a sounding part is arranged on one side close to the buffer cavity. One end of the second pipeline is communicated with the second communication hole, and the other end hermetically wraps the sounding part and is hermetically communicated with the bypass pipeline; the airflow control assembly comprises a butterfly plate arranged in the connecting valve body, a valve plate connected with the side end face of the butterfly plate and a motor in transmission connection with the butterfly plate, and when the motor drives the butterfly plate to rotate, the valve plate selectively closes or opens the second communicating hole; the device can give out specific warning sound in the overload transportation state to effectively recognize whether the vehicle is in the overload state or not, increase exhaust back pressure in the overload transportation state and reduce the active intention of overload of a driver.

    本发明涉及车辆技术领域,具体公开了一种超载报警排气装置、预防超载的报警控制方法及车辆,包括连接阀体,连接阀体外侧壁间隔开设有第一连通孔及第二连通孔;旁通管道,一端与第一连通孔连通,其另一端封堵使管内形成缓冲腔,靠近缓冲腔的一侧设置有发音部。第二管道,一端与第二连通孔连通,其另一端密封包裹发音部与旁通管道密封连通;气流控制组件,包括设于连接阀体内的蝶板、与蝶板侧端面连接的气门板、及与蝶板传动连接的电机,当电机带动蝶板旋转时,气门板选择性关闭或打开第二连通孔,该装置可以在超载运输状态发出特定的警示声音有效的识别车辆是否处于超载状态,以及在超载运输状态增大排气背压,降低驾驶员超载的主动意愿。
