The invention discloses an air supply device for an air brake, which can automatically sense the pressure change in an air tank and can automatically shut down an inflating pump when the air pressure reaches a threshold value. The air supply device for the air brake comprises the air tank, the inflating pump and a driving motor thereof, wherein an air inlet and an air outlet are respectively arranged at two ends of the air tank; the air outlet of the inflating pump is communicated with the air inlet of the air tank; the air supply device for the air brake further comprises a pressure control circuit and a driving motor control device; a pressure sensor is arranged on the air tank close to the air outlet; an output end of the pressure sensor is connected with an input signal end of the pressure control circuit; a linked switch controlled by the pressure control circuit is serially connected with an output control loop of the driving motor control device; and the output end of the driving motor control device is respectively connected with the corresponding input end of the driving motor. The air supply device for the air brake is mainly applied to load-carrying vehicles, such as various passenger cars, trucks, and the like.
Description
technical field [0001] The invention relates to an automobile air brake control system, in particular to an air brake air supply device in the automobile air brake control system. Background technique [0002] In modern passenger cars, the electro-pneumatic brake system and its supporting air supply device mainly composed of an electric air pump and an air storage tank are widely used. At present, the constant pressure air pressure control method is adopted, that is, when the air pressure in the air storage tank is ≥0.8MPa, the unloading valve at the lower end of the air storage tank is opened to release the pressure, so that the air pressure in the air storage tank is maintained at 0.8MPa. The disadvantage of the above-mentioned air supply device is that the electric air pump is always in working condition, which wastes energy. In addition, the electric air pump runs continuously and is prone to strain, which shortens its service life and increases the operating cost of th...
