Description
Technical field
The utility model relates to a kind of draft hitch of automobile-use.
Background technology
In order to improve the automobile ride energy, many automobiles have all adopted the air suspension structure, the air suspension structure that different automobile types adopts is also inequality, the many traditional air suspension structure of employing on light bus and SUV car, traditional every side of air suspension of making guiding mechanism with steel spring all is to make elastic element with an air bellow.Constructional feature is: make guiding mechanism with 1/4 oval steel spring, make elastic element with 2 air bellows, air bellow is placed on the bridge or is placed on the vehicle bridge back.
Conventional air suspension arrangement scheme is used for front suspension more, and air bellow is arranged in the vehicle bridge top.Because the air bellow size is bigger, brings certain difficulty to suspension design.In traditional suspension frame structure, the elastic element effect of having held concurrently of steel spring guide arm, therefore this suspension is called combined type air suspension again, and suspension rate is bigger.
The utility model content
The purpose of this utility model provides a kind of novel guiding mechanism four gas spring air suspensions, makes suspension frame structure more simple, and reduces production costs, thereby satisfy the stability requirement of automobile ride and automobile operation better.
For achieving the above object, the utility model adopts following technical scheme: this novel guiding mechanism four gas spring air suspensions, comprise the steel spring guide arm, air bellow, lateral rod and electric air pump compressed air source unit, the front end of described steel spring guide arm has grasswort, spring carrier on this grasswort and the vehicle frame is hinged, the stage casing of steel spring guide arm is connected with rear driving axle by bolt, the leading portion of every steel spring guide arm and be equipped with an air bellow above the back segment respectively, the upper end of each air bellow is connected with automobile longitudinal girder by the gas spring bracket, and the lower bottom base of air bellow is connected with the steel spring guide arm.Lateral rod one end is connected with the rear driving axle of a side, and the automobile longitudinal girder of the other end and offside is hinged.
Can be connected with Panhard rod between the automobile longitudinal girder of described rear driving axle and homonymy.
The stage casing shape of described steel spring guide arm can be arch or straight shape.
Described steel spring guide arm can be the variable section single-leaf spring, and the thickness of variable-section steel sheet spring guide arm is uniform thickness with two air bellows and three junctions of rear driving axle wherein from grasswort thickening gradually along its length backward.
The utility model has overcome the shortcoming of conventional air suspension, guarantees that automobile has good smooth-going performance and operation stabilization performance, and suspension frame structure is more simple, and productive costs is lower.
The utility model can directly be arranged this kind air suspension structure not changing under the former car front spring spring eye support situation, realizes many kinds, and General design is accomplished conllinear production in the production, can be widely used in the car production.
