Abstract

The invention discloses an air suspension for a trailer capable of improving the anti-roll capability. The air suspension is characterized in that: both sides of a vehicle frame are provided with two guide arm assemblies (3); a reinforcing beam(16) is welded between a left bracket assembly (18) and a right bracket assembly (14); the upper ends of a left reinforcing plate (17) and a right reinforcing plate (15) are welded on a beam of the vehicle frame; the two guide arm assemblies (3) are arranged on inner openings of the left bracket assembly (18) and the right bracket assembly (14) respectively; the left bracket assembly (18) and the right bracket assembly (14) are in bolt connection with the two guide arm assemblies (3) by an eccentric sleeve (1); and the upper ends of both sides of a cap-shaped beam are provided with two gas bag assemblies (9) to bear the vertical load, and the lower ends are fixedly connected with the back ends of the two guide arm assemblies (3) arranged on both sides. The air suspension has the advantages of having good ride comfort and stable operation, and overcoming the defect of poor anti-roll capability existing in the air suspension of the common semi-trailer.

Description

technical field [0001] The invention relates to an air suspension for a trailer. Background technique [0002] At present, most of the trailers produced in our country adopt the leaf spring structure, and its disadvantages are ride comfort, poor stability and serious damage to the road surface. With the improvement of laws and regulations, the country has stricter and stricter restrictions on overloading of transport vehicles, and more and more attention has been paid to the maintenance of expressways. Under such circumstances, trailers with air suspension gradually become the first choice of logistics companies, which promotes the rapid development of trailer air suspension structures. [0003] Ordinary air suspensions for trailers are mainly composed of guide arms and their brackets, airbags and their brackets, shock absorbers and their brackets. The bearing capacity is mainly borne by the airbags, and all lateral forces are borne by the guide arms. Ideal, but average ro...
