Abstract
The utility model discloses a composite air suspension system for a commercial vehicle. The composite air suspension system comprises a bottom Z-shaped variable-cross-section steel plate spring. The front end of the Z-shaped variable-cross-section steel plate spring is connected with a vehicle frame, an air spring and a shock absorber are arranged at the rear end of the Z-shaped variable-cross-section steel plate spring, and the upper end of the air spring and the upper end of the shock absorber are respectively connected with the vehicle frame; the air spring is a diaphragm type air spring and comprises an upper cover plate, a rubber air bag and a plunger from top to bottom, the rubber air bag is divided into an inner covering layer, double cord fabric layers and an outer covering layer from the inside to the outside, and the outer covering layer is a butadiene rubber layer. The composite air suspension system has the advantages that the comfort and the operational stability of the suspension system can be improved owing to an air spring structure; the steel plate spring is used as a guiding dowel bar system and can realize effects of a transverse stabilizer bar, accordingly, guiding and carrying effects and effects of a stabilizer can be realized, and the structure of the composite air suspension system can be greatly simplified.
Description
Technical field
The utility model relates to air suspension of automobile field, is specifically related to a kind of commercial vehicle/comm..vehicle Combined air suspension system.
Background technology
Domestic commercial vehicle is such as the drive axle suspension of autotruck, passenger vehicle still adopts traditional plate spring suspension system substantially at present, it makes full use of the elasticity of leaf spring, although there is good skew back, but because vertical load is all born by leaf spring, under different load, can there is different bendings in leaf spring, cause vehicle frame always changing to the distance on ground, the vibration isolation of this suspension system is poor in addition, and ride comfort is bad; Also have at present part autotruck to adopt full AIRMATIC Dual Control, the normal load of automobile mainly contains air bag and bears, and have lightweight, traveling comfort and the good advantage of operational stability, but the ability of the anti-inclination of this suspension is poor.
Utility model content
The purpose of this utility model is exactly the defect existing for prior art, a kind of commercial vehicle/comm..vehicle Combined air suspension system is provided, it is by being integrated in steel spring and air bellow in same suspension system, the vibration isolation that has solved plate spring suspension system is poor, the poor defect of ability of the defect that ride comfort is bad and the complete anti-inclination of AIRMATIC Dual Control.
Its technical scheme is: comprise the Z-shaped variable-section steel sheet spring of bottom, its front end connecting vehicle frame, rear end are provided with air bellow and bumper, and described air bellow and the upper end of bumper be connecting vehicle frame respectively; Described air bellow is diaphragm type air spring, and it comprises upper cover plate, rubber pneumatic bag and plunger from top to bottom, and described rubber pneumatic bag is divided into internal coating, Double-layer curtain layer of cloth and external coating from inside to outside, and described external coating is butadiene rubber layer.
Described bumper is bitubular oil pressure damper or monotubular pneumatic bumper.
The thickness of described Z-shaped variable-section steel sheet spring first half section diminishes from back to front gradually, is linear change.
The utility model is simple in structure, easy to manufacture, with low cost, reliable and stable, air bellow structure wherein can improve traveling comfort and the operational stability of suspension system, the front end of steel spring plays elastic element simultaneously, rear end is connected with air bellow, because its rigidity is much larger than spring, can regard stiffener as, mainly play power transmission, supporting role, steel spring can play the effect of Panhard rod as power transmission guiding leverage itself, be used for bearing side force, have the effect of guiding, carrying and stabiliser concurrently, greatly simplify the structure.
Accompanying drawing explanation
Fig. 1 is the connection diagram of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of Fig. 1 light plate spring;
Fig. 3 is the structural representation of air bellow in Fig. 1;
In figure: 1, Z-shaped variable-section steel sheet spring, 2, bumper, 3, vehicle frame, 4, longitudinal rod, 5, air bellow, 5.1, upper cover plate, 5.2, external coating, 5.3, the 2nd layers of cord, 5.4, ground floor cord, 5.5, internal coating, 5.6, flange, 5.7 plungers.
The specific embodiment
With reference to Fig. 1-3, a kind of commercial vehicle/comm..vehicle Combined air suspension system, comprise the Z-shaped variable-section steel sheet spring 1 of bottom, the thickness of first half section diminish gradually from back to front (referring to Fig. 1), be linear change, and its front end connecting vehicle frame 3, rear end are provided with air bellow 5 and bumper 2, the upper end of air bellow 5 and bumper 2 is connecting vehicle frame 3 respectively; Air bellow 5 is diaphragm type air spring, and it comprises upper cover plate 5.1, rubber pneumatic bag and plunger 5.7 from top to bottom, and rubber pneumatic bag is divided into internal coating 5.5, Double-layer curtain layer of cloth 5.3-5.4 and external coating 5.2 from inside to outside; The bottom of rubber pneumatic bag is provided with the flange 5.6 for connecting plunger 5.7, and external coating 5.2 is butadiene rubber layer.Bumper 2 is bitubular oil pressure damper or monotubular pneumatic bumper.
Air bellow structure during this use is novel can improve traveling comfort and the operational stability of suspension system, the front end of Z-shaped variable-section steel sheet spring plays elastic element simultaneously, the effect of Panhard rod can be played in rear end as power transmission guiding leverage itself, be used for bearing side force, have the effect of guiding, carrying and stabiliser concurrently, greatly simplify the structure.
Claims (3)
