Abstract: The disclosure relates to an air spring for a vehicle and a vehicle. The disclosure aims to solve the problems of, in an existing air spring for a vehicle, a poor filtering effect and frequent replacement of a filter screen. To this end, an air spring for a vehicle according to the disclosure comprises a dust-proof shade, an inner core and a bladder, wherein the inner core is in the shape of an upwardly open barrel, the dust-proof shade surrounds an outer side of a sidewall of the inner core, the dust-proof shade encloses a chamber with the sidewall of the inner core, and the bladder is arranged inside the chamber; and the sidewall of the inner core is provided with a first breathing hole and a second breathing hole, an inner side of the inner core is in communication with the outside through the first breathing hole, the inner side of the inner core is in communication with the chamber through the second breathing hole, and the first breathing hole and the second breathing hole are both arranged away from a bottom portion of the inner core. The dust and sand is prevented from entering the chamber together with the air, the filtering effect is improved, the bladder arranged inside the chamber is protected from being damaged, and the service life of air spring is increased.

Abstract: The disclosure relates to a vehicle, and an air spring assembly (10) and an upper support (300) thereof. By means of forming an air passing channel (330) in the upper support, pressurized air can flow to an upper surface (320) of the upper support, so as to achieve the balance of air pressure on two sides of the upper support and thus achieve the force balance to avoid receiving force on one side, thereby preventing offset of the stiffness curve of the upper support and prolonging the service life of the upper support.
