Described bracing or strutting arrangement comprises the support air bag being arranged on and vehicle frame laying respectively at both sides before and after described drive axle or floating axle, and described support air bag lower end is connected with equalizer, connects described drive axle or floating axle in the middle part of described equalizer;
Described bracing or strutting arrangement also comprises the upper thrust rod structure and lower thrust rod structure that are arranged at described vehicle frame, described lower thrust rod structure comprises the lower thrust rod support being separately positioned on described vehicle frame both sides, described lower thrust rod pedestal lower end is connected with lower thrust rod separately, and the described lower thrust rod other end all connects and composes V-shaped with middle side part under described drive axle or floating axle;
Described upper thrust rod structure comprises the upper thrust rod being connected to described vehicle frame be positioned at above described lower thrust rod, and the described upper thrust rod other end all connects and composes V-shaped with middle side part on described drive axle or floating axle, thus, part between upper and lower sides in the middle part of described upper thrust rod, drive axle or floating axle, lower thrust rod, lower thrust rod prop up and are configured to two to be placed on the following track bar bracket intersected in the middle part of drive axle or floating axle be the four-bar linkage of fixed link;
Described bracing or strutting arrangement also comprises stabilizator rod structure, and the relatively described four-bar linkage of described stabilization rod mechanism is positioned at the opposite side of described drive axle or floating axle, and described stabilization rod mechanism is connected with described equalizer;
Described bont comprises the fixed support be arranged on vehicle frame, and described fixed support lower end is connected with lower bracket, and described lower bracket is connected with lifting air bag, and described lifting air bag upper end is connected with upper bracket, and described upper bracket connects described floating axle.
Wherein, described vehicle frame is provided with bumper, and described bumper lower end is connected with described equalizer.
When car load is unloaded, the axle load of drive axle and floating axle is less, at this moment floating axle promotes airbag aeration, support air bag is exitted, and along with the height promoting air bag increases, floating axle will be departed from ground by lifting, the axle load of drive axle is increased, thus increase propulsive effort, front tyre wearing and tearing after reducing, are conducive to the economy and the tractive performance that promote car load.
The beneficial effect of this programme can be learnt according to describing of such scheme, structure is simple, reasonable in design, heavy duty truck bridge air suspension device adopts full-floating four gasbags, vehicle frame and bridge bracket are not rigidly connected, air suspension apparatus can reach the vibration of vehicle frame in effective attenuation ground, and ride comfort is good; Drive axle and floating axle are all equipped with Panhard rod, can increase the roll angular rigidity of car load, make vehicle keep lateral stability when turning; Floating axle has lifting air bag, can be promoted to certain altitude, depart from ground completely, can reduce wear on tyres, reduces oil consumption, increases the propulsive effort of drive wheel.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model detailed description of the invention;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the structural representation of floating axle;
In figure, 101 stabilization rod mechanisms, 102 support air bag, 103 balanced fine strains of millet, 104 drive axles, 105 shock absorbers, 106 lower thrust rod supports, 107 lower thrust rods, 108 lifting force pole sockets, 109 upper thrust rods, 110 deep beams, 201 promote air bag, 202 upper brackets, 203 lower brackets, 204 fixed supports, 205 floating axles, 206 lifting force pole socket mounting brackets
Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by detailed description of the invention, this programme is set forth.
As Figure 1-3, the utility model is a kind of heavy duty truck air hanger bracket device for floating axle, comprises drive axle suspension, is provided with floating axle suspension on rear side of drive axle suspension, drive axle suspension comprises bracing or strutting arrangement, and floating axle suspension comprises bracing or strutting arrangement and bont; Bracing or strutting arrangement comprises the support air bag 102 being arranged on and vehicle frame laying respectively at both sides before and after drive axle 104 or floating axle 205, and support air bag 102 lower end is connected with equalizer 103, connects drive axle 104 or floating axle 205 in the middle part of equalizer 103; Bracing or strutting arrangement also comprises the upper thrust rod structure and lower thrust rod structure that are arranged at vehicle frame, lower thrust rod structure comprises the lower thrust rod support 106 being separately positioned on vehicle frame both sides, lower thrust rod support 106 lower end is connected with lower thrust rod 107 separately, and lower thrust rod 107 other end all connects and composes V-shaped with drive axle 104 or floating axle 205 times middle side parts; Upper thrust rod structure comprises the upper thrust rod 109 being connected to vehicle frame be positioned at above lower thrust rod 107, and upper thrust rod 109 other end all connects and composes V-shaped with the lifting force pole socket 108 on the lifting force pole socket mounting bracket 206 of middle side part on drive axle 104 or floating axle 205, thus, in the middle part of upper thrust rod 109, drive axle 104 or floating axle 205, between upper and lower sides, part, lower thrust rod 107, lower thrust rod support 106 form two and are placed on the four-bar linkage that the following track bar bracket 106 intersected in the middle part of drive axle 104 or floating axle 205 is fixed link; Bracing or strutting arrangement also comprises stabilizator rod structure 101, and stabilization rod mechanism 101 relatively four-bar linkage is positioned at the opposite side of drive axle 104 or floating axle 205, and stabilization rod mechanism 101 is connected with equalizer 103; Bont comprises the fixed support 204 be arranged on vehicle frame, and fixed support 204 lower end is connected with lower bracket 203, and lower bracket 203 is connected with and promotes air bag 201, and promote air bag 201 upper end and be connected with upper bracket 202, upper bracket 202 connects floating axle 205.Vehicle frame is provided with bumper 105, and bumper 105 lower end is connected with equalizer 103.
