The invention provides a load sensing proportional valve body and a load sensing proportional valve. The load sensing proportional valve body comprises a valve body, wherein the valve body comprises a back axle brake liquid inlet, an oil pressure adjusting cavity and a brake liquid outlet which are sequentially communicated. The load sensing proportional valve body is characterized in that the valve body also comprises a bypass hole which is used for communicating the back axle brake liquid inlet and the brake liquid outlet; when the brake force of a front axle is not reduced, the bypass hole is sealed, and the back axle brake liquid inlet and the brake liquid outlet are not communicated; when the brake force of the front axle is reduced, the bypass hole is opened, and the back axle brake liquid inlet and the brake liquid outlet are communicated. The load sensing proportional valve body has the advantage that when the brake force of the front axle is reduced, the bypass hole is opened, the back axle brake liquid directly flows from the back axle brake liquid inlet to the brake liquid outlet, and does not flow into the oil pressure adjusting cavity, and the oil pressure of the back axle brake liquid is not reduced, so the brake force of a whole automobile is guaranteed, and the driving safety of the automobile is improved.
