Abstract: The present invention relates to an air foil thrust bearing including a bump foil and a top foil stacked at a position corresponding to the bump foil to cover the bump foil, in which an outer diameter of the top foil is larger than an outer diameter of the bump foil in a radial direction, and the bump foil and the top foil are formed and disposed so that a portion where pressure of an air film between a thrust runner and the top foil is high when a rotor rotates is consistent with a region in which the bump foil exists, such that friction in an outermost peripheral region of the top foil based on the radial direction is reduced, durability is improved, the pressure of the air is relatively uniformly dispersed, and a load supporting force is improved.

Abstract: The present invention relates to an air foil journal bearing including a bump foil having a plurality of elastic bumps and provided and coupled inside a bearing housing, a mid-foil provided inside the bump foil, formed in a circumferential direction, and having at least one circumferential end coupled to the bearing housing, and a top foil provided inside the mid-foil, formed in the circumferential direction, and having at least one circumferential end coupled to the bearing housing, in which a stepped portion is formed as a radius of an inner peripheral surface of a partial circumferential region of the mid-foil is smaller than a radius of an inner peripheral surface of the remaining region, such that an additional pressure is generated in a section in which a maximum positive pressure is applied when a rotor rotates at low speed, such that the rotor may float at a relatively low rotational speed, and friction and vibration between the rotor and the top foil may be reduced.

Abstract: The present invention relates to an air compressor for a vehicle and, more specifically, to an air compressor for a vehicle wherein the entire operation of the air compressor may be stabilized by a cooling unit in which a portion of the compressed air that moves through a connection pipe conveying primarily compressed air exchanges heat with a cooling water flowing part to cool the driving unit.
