The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1 to Figure 3, the AIRMATIC Dual Control of multi-axle smei-trailer of the present invention, comprise load-carrying air bag 1, swing arm 3 and the first permanent seat 4, the middle part of swing arm 3 is fixedly connected with vehicle bridge 6 by U-bolt 8, the first permanent seat 4 is bolted in the below of vehicle frame (not shown), and one end of swing arm 3 is articulated with on the first permanent seat 4.Load-carrying air bag 1 is installed between the other end and vehicle frame of swing arm 3, and specifically, the lower end of load-carrying air bag 1 is fixedly connected with swing arm 3 by bolt, and the upper end of load-carrying air bag 1 is fixedly connected with vehicle frame by bolt.AIRMATIC Dual Control is also equiped with for promoting the lift system of vehicle bridge 6, this lift system comprises the second permanent seat 5 that promotes air bag 2 and be fixedly connected with vehicle frame, the second permanent seat 5 is positioned at the below of swing arm 3, and promoting air bag 2 is installed between the second permanent seat 5 and swing arm 3, specifically, the lower end that promotes air bag 2 is fixedly connected with the second permanent seat 5 by bolt, the affixed upper cover plate 21 in upper end that promotes air bag 2, upper cover plate 21 for example, is fixedly connected with swing arm 3 by fastener (combination of bolt and back plate).Above-mentioned load-carrying air bag 1 and lifting air bag 2 all adopt the existing air bag for vehicle air suspension.
The AIRMATIC Dual Control of multi-axle smei-trailer of the present invention by lift system is set, can promote unnecessary vehicle bridge 6 to make tire depart from ground, and then reduce rolling resistance under superimposed trailer light condition, reduces oil consumption, has also reduced the wearing and tearing of tire, has extended service life; The main function components of the lift system that the present invention adopts consists of the second permanent seat 5, lifting air bag 2 and upper cover plate 21, the upper cover plate 21 that promotes air bag 2 is fixedly connected with swing arm 3 by fastener, centre does not arrange other guiding mechanisms, without relative sliding, with respect to the lift system of existing superimposed trailer, there is the advantages such as simple and compact for structure, stable working, lightweight, reasonable in design, stressed property be better, convenient for installation and maintenance.It is the multi-axle smei-trailer of 9 to 13 tons that this AIRMATIC Dual Control is particularly useful for single shaft axle load.
In the present embodiment, promote air bag 2 between the first permanent seat 4 and vehicle bridge 6, the first permanent seat 4, lifting air bag 2, vehicle bridge 6 and load-carrying air bag 1 are connected on swing arm 3 successively, make like this hoisting depth of vehicle bridge 6 larger.
