Detailed description of the invention
As depicted in figs. 1 and 2: a kind of heavy motor vehicle air suspension, comprising: symmetrically before and after two equalizer assemblies, 1, Panhard rod, 2, two propelling rods, 3, four air bags, 4, four bumpers 5 and two fixed mounts, 6, two equalizer assemblies 1 to place; Equalizer assembly 1 is C type, comprises arm-tie assembly 11, air bag mounting seat 12 and bumper mount pad 13; Arm-tie assembly 11 is arranged on the middle part of equalizer assembly 1 and wraps equalizer assembly 1 in " mouth " font, arm-tie assembly 11 upper end is provided with Panhard rod mount pad 7, the two ends of Panhard rod 2 are arranged on the Panhard rod mount pad 7 of two equalizer assemblies 1 respectively, thus realize the connection of two equalizer assemblies 1; The upper end of arm-tie assembly 11 is also provided with the adapter plate 6 for fixed car axletree, and the lower end of arm-tie assembly 11 is provided with propelling rod mount pad 8, and propelling rod mount pad 8 realizes the installation with propelling rod 3 by boatswain chair 9; Air bag mounting seat 12 is arranged on the two ends of equalizer assembly 1, air bag mounting seat 12 comprises spacer 122 and disk 121, spacer 122 one end is welded with disk 122, the other end welds with equalizer assembly 1, disk 122 offers tapped bore, offer the outside thread suitable with disk 122 upper screwed hole bottom air bag 4, air bag 4 is threaded connection, and is fixed on air bag mounting seat 12; The front end of bumper mount pad 13 is protruding from the both ends horizontal of equalizer assembly 1, and rear end is arranged on equalizer assembly 1, and the front end of bumper mount pad 13 offers the hole for mounting shock absorber 5, and bumper 5 realizes axle with bumper mount pad 13 and is connected.
Principle of work of the present utility model and using method are: as shown in Figure 3 and Figure 4, Automobile shaft 100 is through two adapter plates 6, and with bolt, adapter plate 6 and Automobile shaft 100 being fixed on arm-tie assembly 11, the two ends of Automobile shaft 100 are all provided with automotive hub 101; One end of propelling rod 3 is connected with the propelling rod mount pad 12 on equalizer assembly 1 by bolt, and the other end and automobile chassis frame 102 are bolted; One end of air bag 4 is arranged on the air bag mounting seat 12 on equalizer assembly 1, and the other end is arranged on automobile chassis frame 102; One end of bumper 5 is arranged on the bumper mount pad 13 on equalizer assembly 1, and the other end is arranged on automobile chassis frame 102; Automobile chassis frame 102 is provided with height-control valve 103, one end of height-control valve 103 is connected with Automobile shaft 100 by connecting rod.
When there are vibrations in vehicle, the automobile chassis frame 102 that height-control valve 103 is housed will move down, the connecting rod connecting vehicle bridge and height-control valve 103 can rotate, and drive cam shaft to carry out rotating and then make piston and push rod to move up, now, the inlet valve of air bag 4 is opened, pressurized air enters air bag 4 from admission port, make the air pressure of air bag 4 increase, the height of air bag 4 increases, and automobile chassis frame 102 is also elevated; After automobile chassis frame 102 is elevated, connect Automobile shaft 100 and can rotate backward with the connecting rod of height-control valve 103, make the Intake Valve Closes of air bag 4, now height-control valve 103 is in the state of a balance; When automobile chassis frame 102 is subject to larger vibrations, its descending speed can accelerate, and the aeration speed of air bag 4 is slow, cannot play the effect of damping at once, now, the bumper 5 be connected with automobile chassis frame 102 plays a role, and automobile chassis frame 102 is played to the effect of support, to reduce the descending speed of automobile chassis frame 102, when air bag 4 is inflated to a certain degree, together with bumper 5, support automobile chassis frame 102, until automobile chassis frame 102 gets back to settling position; When automobile turning, vehicle body can roll, and the suspension of both sides is beated inconsistent, the suspension in outside can apply certain power to Panhard rod 2, now, Panhard rod 2 will distortion, and the elastic force of its shaft can stop lifting of wheel, and then make vehicle body keep balance, thus play laterally stable effect as far as possible.
Comprehensive above feature can be found out, the utility model structure is simple, and adopts air bag to be used for buffering automobile vibrations, because air bag has variable rigidity, thus the stationarity of running car can well be improved, but also the noise produced in vehicle operating can be reduced.
The utility model is not limited to above-mentioned embodiment, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these changes and distortion.
