Abstract
The utility model provides an air spring suspension for an automobile. The air spring suspension comprises an air spring and an airbag mounting beam. The air spring consists of a first air spring and a second air spring. The bottom of the first air spring is connected with a first end of an airbag supporting beam by virtue of a bolt, and the bottom of the second air spring is connected with a second end of the airbag supporting beam by virtue of a bolt. The top parts of the first air spring and the second air spring are connected with an automobile frame by virtue of a bolt. As an airbag is in a dual-airbag structure, the loading capacity is large. A trust rod is inversely arranged, so that the use ratio of the space at the inner side of the automobile frame is higher. Under the same loading requirement, the system pressure in the airbag is smaller. The diameter of the airbag can be reduced at the same pressure, so that the air spring suspension can be conveniently mounted in an entire automobile. The cross section of the air supporting beam is in an 'H'-shaped structure, so that the rigidness and the loading capacity are better. The bottom of the airbag is connected with the supporting beam by virtue of one bolt, so that the air spring suspension is convenient to mount and dismount.
Description
Technical field
The utility model relates to and a kind ofly being used for, the suspension of heavy motor vehicle, relates in particular to a kind of automobile and uses air spring suspension.
Background technology
Be used for now, the air spring suspension of heavy motor vehicle, its air bag all adopts one, its load-carrying capacity a little less than; And the propelling rod that is used for drive axle guiding is employed in the pattern of vehicle frame disposed inboard, and vehicle frame inner space degree of utilization is lower.
The utility model content
The purpose of the utility model is to provide a kind of automobile to use air spring suspension, the load-carrying capacity of increase suspension system, propelling rod employing side pattern, raising vehicle frame inner space degree of utilization.
The automobile of the utility model comprises air bellow and air bag mounting rail with air spring suspension; Said automobile is characterised in that with air spring suspension: said air bellow is made up of first air bellow and second air bellow; In first end of said air bag support beam, bolted connection is passed through in second end of said air bag support beam in the bottom of said second air bellow through bolted connection in the bottom of said first air bellow; The top of said first air bellow and second air bellow is connected with the vehicle frame of automobile through bolt.
The utility model has the advantages that: air bag adopts the structural shape of two air bags, and load-carrying capacity is big; Propelling rod adopts the side pattern, and vehicle frame inner space degree of utilization is higher; Under same load required, system pressure was less in the air bag; With the diameter that can reduce air bag under the equipressure, be convenient in car load, install; Air bag supports beam section and adopts " worker " font structure, and rigidity and load-carrying capacity are better; A bolted connection, easy accessibility are adopted with being connected of support beam in the air bag bottom.
