Abstract: The present invention relates to a compressor and, more specifically, to an air compressor for a vehicle, which can support a rotor disk and form a cooling flow channel by a first cover and a second cover, and thus can improve cooling efficiency while increasing manufacturability.

Abstract: The present invention relates to an air foil journal bearing in which air is introduced between a foil and a rotor rotating at high speed and generates pressure to support a radial load of the rotor and allow the rotor to rotate smoothly, and more particularly, to a housing fixing structure of an air foil journal bearing that improves durability against external impact or vibration by restricting an axial movement of a bump by means of two opposite ends of the bump and a top foil fixing portion.

Abstract: An air compressor according to an aspect of the present invention comprises: a housing; a rotating shaft which is disposed in the housing; a compression unit which is connected to the rotating shaft to compress and discharge inlet air; a motor unit which drives the rotating shaft; a control board which controls the motor unit; and a filter unit which filters out noise from external power and supplies the external power to the control board, wherein the housing includes a first cooling flow channel for cooling the motor unit and a second cooling flow channel for cooling the filter unit, and the first cooling flow channel communicates with the second cooling flow channel.

Abstract: The present invention relates to an air compressor which improves the space utilization of a filter unit, and reduces the number of constituent parts constituting the filter unit, thereby improving assemblability, reducing manufacturing costs, and minimizing the size of the air compressor itself. The air compressor comprises: a housing; a rotating shaft extending in the longitudinal direction inside the housing; a compression unit disposed in front of the rotating shaft and rotated by the rotating shaft to compress and discharge air that flows in; a motor unit which rotates the rotating shaft; a control board which controls the motor unit; a filter unit which supplies external electrical power to the control board and filters the noise of the electrical power; and a bus bar assembly which transfers the electrical power from the control board to the motor unit.

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.

Abstract: A vehicle air compressor including a shaft provided with an impeller disposed at one side thereof and a runner disposed at the other side thereof, a motor configured to rotate the shaft, a trust bearing which supports the shaft in a longitudinal direction of the shaft and of which a surface is disposed adjacent to a surface of the runner, wherein a cooling hole for cooling air between the trust bearing and the runner is disposed in the trust bearing.
