Abstract: Disclosed herein is an air compressor. The air compressor may include: a compressor unit including a front housing having a front inlet and a compressor scroll, and a compressor impeller configured to transfer the air drawn through the front inlet toward the compressor scroll; a motor unit including a motor housing coupled with the front housing, a stator disposed along an inner circumferential surface of the motor housing, and a rotor disposed to pass through the stator and coupled with the compressor impeller by a rotating shaft; a turbine unit including a rear housing coupled with the motor housing, a turbine impeller coupled with the rotating shaft, and a turbine blower formed in the rear housing and configured to exhaust air that has passed through the turbine impeller to the outside; and an air cooling unit coupled with the compressor scroll to cool the stator and the rotating shaft.

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.

Abstract: Disclosed herein is an air foil bearing capable of adjusting stiffness of single bumps by varying widths of the single bumps. Since the bumps have the same height in an initial stage, a wedging effect is implemented only when a load is applied thereto by an oil film. Therefore, the air foil bearing is advantageous in terms of height management thereof. In addition, it is possible to stably dampen shocks applied in the direction of rotation of a rotor, to improve a support capability, and to reduce shocks due to damping. Therefore, it is possible to enhance durability of the air foil bearing.
