BUSHING ASSEMBLY, CONTROL ARM, AND VEHICLE

WIPO Patent Application WO/2023/093459

A1

A bushing assembly (100), a control arm (200) and a vehicle. The bushing assembly (100) comprises an inner tube (1), an outer tube (2), an elastic support portion (3) and an airbag (4). The inner tube (1) is provided with a connecting through hole (11), and the outer tube (2) is sleeved on the outer side of the inner tube (1) and is coaxially arranged with the inner tube (1). The elastic support portion (3) fills a space between the inner tube (1) and the outer tube (2), and an accommodating space (31) is formed on the elastic support portion (3). The airbag (4) is arranged in the accommodating space (31). Such a design enables the airbag (4) to bear a radial acting force when a vehicle is accelerated or braked, thereby avoiding stretching and abrasion of the elastic support portion (3) from an external load, and then improving the durability and prolonging the service life of the bushing assembly (100). In addition, the airbag (4) improves a shock-absorbing effect of the bushing assembly (100), thus improving the comfort of the vehicle.
