。 An air spring interposed between the rear axle and the chassis frame, an air suspension tank that supplies compressed air to the air spring, and fluid pressure that operates the rear wheel brake in response to the air pressure in the air spring. A load sensing proportioning valve that controls the load sensing, an auxiliary air tank that stores compressed air inside, and an air suspension that is installed between the auxiliary air tank and the load sensing proportioning valve, and is normally closed. An air suspension comprising an emergency normally closed valve that opens when the air pressure in the auxiliary air tank drops below a set value and supplies compressed air in the auxiliary air tank to the load sensing proportioning valve. Brake control device for cars.
